If k_thread_join() was passed with an actual timeout value,
and not K_FOREVER, the blocking thread was not being properly
woken up when the target thread exits. The timeout itself
was never aborted, causing the joining thread to remain
un-scheduled until the timeout expires.
Amend the k_thread_join() test cases to check that the join
completed before the provided timeout period expired.

This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this

used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of

The test of the absolute timeout feature was a simple whitebox test
that inspected the generated ticks field of different constructors for
identity. But it wasn't simple enough, because it was doing a
ticks->ms->ticks conversion (at compile time, sigh) on the input data,
which is obviously lossy on platforms where ticks are shorter than
milliseconds by non-integral factors.
Fix to do the conversion in just one direction.

This test sets a timer, busy waits for half the duration, and then
checks the remaining time is correct. And it correctly does all its
math in tick precision and aligns to a timer interrupt to eliminate
aliasing due to the tick stride.
But it's waiting using k_busy_wait(), not a timer: "half the duration"
in MICROSECONDS (for k_busy_wait()) is not necessarily representable
as an integer number of TICKS on all platforms. Because k_busy_wait()
always rounds up, we need one extra tick of buffer on those platforms.

These five tests (mbox_api, mheap_api_concept, msgq_api, pipe_api and
queue) all had test cases where they needed a mem_pool allocation to
FAIL. And they are all written to assume the behavior of the original
allocator and not the more general k_heap code, which actually
succeeds in a bunch of these cases.
* Even a very small heap saves enough metadata memory for the very
small minimum block size, and this can be re-used as an allocation.
So you can't assume a small heap is full.
* Calculating the number of blocks based on "num_blocks * max size /
minimum size" and allocating them does not fill the heap, because
the conservative metadata reservation leaves some space left over.
So these have all been modified to "fill" a heap by iteratively
allocating until failure.
Also, this fixes a benign overrun bug in mbox. The test code would
insert a "big" message by reading past the end of the small message
buffer. This didn't fail because it happened to be part of an array
of messages and the other ones defined contained the memory read. But
still.

The original k_mem_pool tests were a mix of code that tests routine

specific memory layout of the original allocator, which doesn't run
out of memory in exactly the same way.
Adjust the expectations as needed for the backend. A few test cases
were skipped if they were too specific. Most have been generalized
(for example, iteratively allocating to use up all memory instead of
assuming that it will be empty after N allocations).

k_ticks_t used in timeout computations pervasively 64 bit. This will

upcoming commit.

Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument. Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created. This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.
The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.
The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.
Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.
For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided. When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.
Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions. These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig. These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.
k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.
Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate. Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure. But k_poll() does not fail
spuriously, so the loop was removed.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

The current nested interrupt test implementation is both buggy and
fundamentally flawed because it does not trigger a higher priority
interrupt from a lower priority interrupt context and relies on the
system timer interrupt, which is not fully governed by the test;
moreover, the current implementation does not properly validate the
test results and can report success if no interrupt is triggered and
serviced at all.
This commit reworks this test to have the following well-defined
and logical procedure:
1. [thread] Trigger IRQ 0 (lower priority)
2. [isr0] Set ISR 0 result token and trigger IRQ 1 (higher priority)
3. [isr1] Set ISR 1 result token and return
4. [isr0] Validate ISR 1 result token and return
5. [thread] Validate ISR 0 result token
The reworked test scenario ensures that the interrupt nesting works
properly and any abnormal conditions are detected (e.g. interrupts not
triggering at all, or ISR 1 not being nested under ISR 0).

ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.
This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).
So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.

The minimum possible mempool block size is either 8 or 16 for 32-bit or
64-bit targets respectively. Defining BYTES_TO_WRITE to 4 and using that
with K_MEM_POOL_DEFINE() won't produce the expected result i.e. only 1
block at any time could be allocated instead of 4.
Yet, the test does run successfully regardless of the block allocation
loop in tpipe_block_put().
It turns out that the pipe buffer is large enough to consume all the
block data synchronously, meaning that the mempool block is freed right
away and available for the next loop iteration. This also means that the
asynchronous delivery mechanism is never exercized.
Fix both issues by defining PIPE_LEN and BYTES_TO_WRITE in terms of
_MPOOL_MINBLK with the expected factor of 4, and adding a new test
using the half-sized pipe where the pipe buffer gets saturated and
mempool memory blocks are actually queued for asynchronous consumption.

This test has a problem, specifically in the scenario for
test_mem_domain_remove_partitions. A low priority thread (10)
is created which is expected to produce an exception. Then
the following happens:
- The thread indeed crashes and ends up in the custom fatal
error handler, on the stack used for exceptions
- The call to ztest_test_pass() is made
- ztest_test_pass() gives the test_end_signal semaphore
- We then context switch to the ztest main thread which is
higher priority, leaving the thread that crashed context
switched out *on the exception stack*
- More tests are run, and some of them also produce exceptions
- Eventually we do a sleep and the original crashed thread is
swapped in again
- Since several other exceptions have taken place on the
exception stack since then, resuming context results in
an unexpected error, causing the test to fail
Only seems to affect arches that have a dedicated stack for
exceptions, like x86_64. For now, increase the priority of
the child thread so it's cleaned up immediately. Longer-term,
this all needs to be re-thought in the test case to make this
less fragile.

This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.
The refactoring strategy used in this commit is detailed in the issue
This commit introduces the following major changes:
1. Establish a clear boundary between private and public headers by
removing "kernel/include" and "arch/*/include" from the global
include paths. Ideally, only kernel/ and arch/*/ source files should
reference the headers in these directories. If these headers must be
used by a component, these include paths shall be manually added to
the CMakeLists.txt file of the component. This is intended to
discourage applications from including private kernel and arch
headers either knowingly and unknowingly.
- kernel/include/ (PRIVATE)
This directory contains the private headers that provide private
kernel definitions which should not be visible outside the kernel
and arch source code. All public kernel definitions must be added
to an appropriate header located under include/.
- arch/*/include/ (PRIVATE)
This directory contains the private headers that provide private
architecture-specific definitions which should not be visible
outside the arch and kernel source code. All public architecture-
specific definitions must be added to an appropriate header located
under include/arch/*/.
- include/ AND include/sys/ (PUBLIC)
This directory contains the public headers that provide public
kernel definitions which can be referenced by both kernel and
application code.
- include/arch/*/ (PUBLIC)
This directory contains the public headers that provide public
architecture-specific definitions which can be referenced by both
kernel and application code.
2. Split arch_interface.h into "kernel-to-arch interface" and "public
arch interface" divisions.
- kernel/include/kernel_arch_interface.h
* provides private "kernel-to-arch interface" definition.
* includes arch/*/include/kernel_arch_func.h to ensure that the
interface function implementations are always available.
* includes sys/arch_interface.h so that public arch interface
definitions are automatically included when including this file.
- arch/*/include/kernel_arch_func.h
* provides architecture-specific "kernel-to-arch interface"
implementation.
* only the functions that will be used in kernel and arch source
files are defined here.
- include/sys/arch_interface.h
* provides "public arch interface" definition.
* includes include/arch/arch_inlines.h to ensure that the
architecture-specific public inline interface function
implementations are always available.
- include/arch/arch_inlines.h
* includes architecture-specific arch_inlines.h in
include/arch/*/arch_inline.h.
- include/arch/*/arch_inline.h
* provides architecture-specific "public arch interface" inline
function implementation.
* supersedes include/sys/arch_inline.h.
3. Refactor kernel and the existing architecture implementations.
- Remove circular dependency of kernel and arch headers. The
following general rules should be observed:
* Never include any private headers from public headers
* Never include kernel_internal.h in kernel_arch_data.h
* Always include kernel_arch_data.h from kernel_arch_func.h
* Never include kernel.h from kernel_struct.h either directly or
indirectly. Only add the kernel structures that must be referenced
from public arch headers in this file.
- Relocate syscall_handler.h to include/ so it can be used in the
public code. This is necessary because many user-mode public codes
reference the functions defined in this header.
- Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
necessary to provide architecture-specific thread definition for
'struct k_thread' in kernel.h.
- Remove any private header dependencies from public headers using
the following methods:
* If dependency is not required, simply omit
* If dependency is required,
- Relocate a portion of the required dependencies from the
private header to an appropriate public header OR
- Relocate the required private header to make it public.

This patch is a preparatory step in enabling the MMU in
long mode; no steps are taken to implement long mode support.
We introduce struct x86_page_tables, which represents the
top-level data structure for page tables:
- For 32-bit, this will contain a four-entry page directory
pointer table (PDPT)
- For 64-bit, this will (eventually) contain a page map level 4
table (PML4)
In either case, this pointer value is what gets programmed into
CR3 to activate a set of page tables. There are extra bits in
CR3 to set for long mode, we'll get around to that later.
This abstraction will allow us to use the same APIs that work
with page tables in either mode, rather than hard-coding that
the top level data structure is a PDPT.
z_x86_mmu_validate() has been re-written to make it easier to
add another level of paging for long mode, to support 2MB
PDPT entries, and correctly validate regions which span PDPTE
entries.

mmustructs.h.

Disabling SMP mode for certain tests was a one-release thing, done to
avoid having to triage every test independently (MANY are not
SMP-safe), and with the knowledge that it was probably hiding bugs in
the kernel.
Turn it on pervasively. Tests are treated with a combination of
flagging specific cases as "1cpu" where we have short-running tests

setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still
runs the full SMP kernel config, but with only one CPU available).

This test was testing for an undocumented and somewhat hyperspecific
behavior: when a process reaches a reschedule point and yields to a
higher priority thread, and there is another equal priority thread
active, which thread gets to run when the higher priority thread
finishes its work? The original scheduler (because it leaves the
older thread in place in the list) implements the preemption like an
interrupt and returns to the original thread, despite the fact that
this then resets is time slice quantum unfairly. In SMP mode, where
the current threads cannot live in the active list, the thread gets
added back to the end of the queue and the other thread runs. In
effect, in UP mode "yield" and "reschedule" mean very slightly
different things where in SMP they act the same.
We don't document either behavior, as it happens. Relax the test
constraints by adding a single deliberate k_yield() to unify behavior.

System call arguments, at the arch layer, are single words. So
passing wider values requires splitting them into two registers at
call time. This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.
Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths. So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.
Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types. So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*(). The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function. It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.
This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs. Future commits will port the less testable code.

XIP support in x86 was something of a mess. This
patch does the following:
- Generic ia32 SOC no longer defines a "flash" region
as generic X86 devices don't have a microcontroller-
like concept of flash. The same has been done for apollo_lake.
- Generic ia32 and apollo_lake SOCs starts memory at 1MB.
- Generic ia32 SOC may optionally have CONFIG_XIP enabled.
The board definition must provide a flash region definition
that gets exposed as DT_PHYS_LOAD_ADDR.
- Fixed definitions for RAM/ROM source addresses in ia32's
linker.ld when XIP is turned off.
- Support for enabling XIP on apollo_lake SOC removed, there's
no use-case.
- acrn and gpmrb boards have flash and XIP related definitions
removed.
- qemu_x86 has a fake flash region added, immediately after system
RAM, for use when XIP is enabled. This used to be in the ia32 SOC.
However, the default for qemu_x86 is to now have XIP disabled.
- Fixed tests/kernel/xip to run by default on boards that enable
XIP by default, plus an additional test to exercise XIP on
qemu_x86 (which supports it but has XIP switched off by default)
The overall effect of this patch is to:
- Remove XIP configuration for SOC/boards where it does not make
any sense to have it
- Support testing XIP on qemu_x86 via tests/kernel/xip, but leave
it off by default for other tests, to ensure it doesn't bit-rot
and that the system works in both scenarios.
- XIP remains an available feature for boards that need it.

Nordic platforms measure ticks in cycles of a 32 KiHz clock for which
the minimum compare delay is 2 ticks. The test assumed an upper bound
of four ticks delay per loop iteration, resulting from alignment at
various layers. This delay is met on Nordic for tick rates at or below
16384, but is too short for the default 32768 Hz tick rate.
Instrumentation confirms that the usleep test loop body on Nordic at 32
KiHz ticks takes 3 ticks as the optimum delay, only when a debug probe
is active. In other circumstances it can take either 5 or 6 ticks,
depending on timer alignment and stability.
Relax the upper bound for platforms using this system timer at the
highest rate.

Platforms which use the GEN_SW_ISR mechanism for interrupt handling
can make use of a really simple whitebox trick for verifying that it
worked (i.e. that the pointer and argument get placed in the table
correctly).
Easy and simple way to get some coverage for dynamic IRQs, which is
currently entirely missing. Long term we'll want to replace this with
a test that uses the API directly and chooses an arch-specific vector
to set, and triggers it using arch-specific code, but that's quite a
bit more effort and for now we need to land patches to
z_irq_connect_dynamic() which show test coverage.

here the value is just regular memory marked volatile for

doesn't know that).
Refactor a little so we always read the variable in a way the tool can

Previously, context switching on x86 with memory protection
enabled involved walking the page tables, de-configuring all
the partitions in the outgoing thread's memory domain, and
then configuring all the partitions in the incoming thread's
domain, on a global set of page tables.
We now have a much faster design. Each thread has reserved in
its stack object a number of pages to store page directories
and page tables pertaining to the system RAM area. Each
thread also has a toplevel PDPT which is configured to use
the per-thread tables for system RAM, and the global tables
for the rest of the address space.
The result of this is on context switch, at most we just have
to update the CR3 register to the incoming thread's PDPT.
The x86_mmu_api test was making too many assumptions and has
been adjusted to work with the new design.

Existing test checking value returned by k_delayed_work_remaining_get()

1) The k_delayed_work_remaining_get() should return 0 for non-submitted

2) The k_delayed_work_remaining_get() should return value greater or
equal to the timeout value of just submitted work.
Unfortunately, the second check is not correct. The value returned
by the k_delayed_work_remaining_get() just after submitting delayed
work should be:
- Equal to timeout of the submitted work if no timer interrupt was
executed between submitting work and checking remaining time.
OR
- Less than timeout of the submitted work if a timer interrupt was

This test was written to properly align its millisecond-measured wait
time and assumed that there would be no other overhead. In fact on
fast tick rate systems (or even ones where the alignment computation
doesn't provide the needed padding as "slop") that's not quite enough
time to complete the full test. There are cycles between the sleep
calls that need to be accounted for, and aren't.

This test was written to assume ~100 Hz ticks in ways that are
difficult to fix. It wants to sleep for periods on the order of the
TICKLESS_IDLE_THRESH kconfig, which is extremely small on high tick
rate systems and (on nRF in particular) does not have a cleanly
divisible representation in milliseconds.
Fixing precision issues by cranking the idle threshold up on a
per-system basis seems like an abuse, as that is what we want to be
testing in the first place. Just let the test run at the tick rate it
has always expected.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The logic about minimal sleep sizes due to "tick" aliasing was
correct, but drivers also have similar behavior with "cycle" aliasing
too. When cycles are 3-4 orders of magnitude faster than ticks, it's
undetectable noise. But now on nRF they're exactly the same and we
need to correct for that, essentially doubling the number of ticks a
usleep() might wait for.
The logic here was simply too strict, basically. Fast tick rates
can't guarantee what the test promised.
Note that this relaxes the test bounds on the other side of the
equation too: it's no longer an error to usleep() for only one tick
(i.e. an improved sleep/timeout implementation no longer gets detected
as a test failure).
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The sleep test was checking that the sleep took no longer than "2
ticks" longer than requested. But "2 ticks" for fast tick rate
configurations can be "zero ms", and for aliasing reasons it's always
possible to delay for 1 unit more than requested (becuase you can
cross a millisecond/tick/whatever boundary in your own code on either
side of the sleep). So that "slop" value needs to be no less than
1ms.

The test for the k_uptime_delta utilities was calling it in a loop and
waiting for the uptime to advance. But the code was specifically
wanting it to advance 5ms or more at one go, which clearly isn't going
to work for a tick rate above 200 Hz.
The weird thing is that the test knew this and even commented about
the limitation. Which seems silly: it's perfectly fine for the clock
to advance just a single millisecond. That's correct behavior too.
Let's test for that, and it will work everywhere.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
When ticks are sub-millisecond, the math produces minimum and maximum
values for the slice duration test that are equal. But because of
aliasing across tick boundaries, it's always possible (for any time
period, nothing specific to time slicing here) to measure one tick
more than an intended duration. So make sure there's always at least
a range of 1ms.

Tick rate is becoming a platform tunable in the tickless world. Some
apps were setting it due to requirements of drivers or subsystems (or
sometimes for reasons that don't make much sense), but the dependency
goes the other way around now: board/soc/arch level code is
responsible for setting tick rates that work with their devices.
A few tests still use hard-configured tick rates, as they have
baked-in assumptions (like e.g. "a tick will be longer than a
millisecond") that need to be addressed first.

If maxsize is smaller than _MPOOL_MINBLK, then Z_MPOOL_LVLS() will be 0.
That means the loop in z_sys_mem_pool_base_init() that initializes the
block free list for the nonexistent level 0 will corrupt whatever memory
at the location the zero-sized struct sys_mem_pool_lvl array was
located. And the corruption happens to be done with a perfectly legit
memory pool block address which makes for really nasty bugs to solve.
This is more likely on 64-bit systems due to _MPOOL_MINBLK being twice
the size of 32-bit systems.
Let's prevent that with a build-time assertion on maxsize when defining
a memory pool, and adjust the affected test accordingly.

This mechanism had multiple problems:
- Missing parameter documentation strings.
- Multiple calls to k_thread_name_set() from user
mode would leak memory, since the copied string was never
freed
- k_thread_name_get() returns memory to user mode
with no guarantees on whether user mode can actually
read it; in the case where the string was in thread
resource pool memory (which happens when k_thread_name_set()
is called from user mode) it would never be readable.
- There was no test case coverage for these functions
from user mode.
To properly fix this, thread objects now have a buffer region
reserved specifically for the thread name. Setting the thread
name copies the string into the buffer. Getting the thread name
with k_thread_name_get() still returns a pointer, but the
system call has been removed. A new API k_thread_name_copy()
is introduced to copy the thread name into a destination buffer,
and a system call has been provided for that instead.
We now have full test case coverge for these APIs in both user

Unfortunately this seems to have introduced spurious failures on (at
least) qemu_x86 and qemu_xtensa.
The change limits the timeslice tolerance to +/- 1ms, which isn't
necessarily correct when the tick rate is less than 1ms (though it
will probably work on deterministic hardware as long as the system is
hitting the target at exactly the right tick), and isn't even
theoretically achievable on emulation environments where timing
granularity is limited by the host scheduling quantum.
What this needs to do is check the deadline is off by at most one
tick, and trust the platform integration to have set the tick rate
appropriately.
(I do worry that the earlier version of the test was trying to set the
limit at half the TICKLESS_IDLE_THRESHOLD, though -- that seems weird,

YAML document separators are needed e.g. when doing
$ cat doc1.yaml doc2.yaml | <parser>
For the bindings, we never parse concatenated documents. Assume we don't
for any other .yaml files either.
Having document separators in e.g. base.yaml makes !include a bit
confusing, since the !included files are merged and not separate
documents (the merging is done in Python code though, so it makes no
difference for behavior).
The replacement was done with
$ git ls-files '*.yaml' | \
xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//'
First pattern removes ... at the end of files, second pattern clears a
line with a lone --- on it.
Some redundant blank lines at the end of files were cleared with
$ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}'

Using void pointers as universal arguments is widely used. However, when
compiling a 64-bit target, the compiler doesn't like when an int is
converted to a pointer and vice versa despite the presence of a cast.
This is due to a width mismatch between ints (32 bits) and pointers
(64 bits). The trick is to cast to a widening integer type such as
intptr_t and then cast to
void*.
When appropriate, the INT_TO_POINTER macro is used instead of this
double cast to make things clearer. The converse with POINTER_TO_INT
is also done which also serves as good code annotations.
While at it, remove unneeded casts to specific pointer types from void*
in the vicinity, and move to typed variable upon function entry to make
the code cleaner.

The NSIM emulator has severe performance issues when

Disable runtime reprogramming of the MPU for these

is disabled.
I have assurances from the ARC team that the tests run fine

For 1.15, this will be completely resolved by optimizing
MPU region gap-filling to not take place during context
switch time, which will drastically reduce the number of
MPU registers poked during context switch on nsim_sem.

Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
For obvious performance reasons, scheduler state changes (other than
aborting a thread) do not cause synchronous interrupts on the other

synchronously if it's high priority, but if you want to see it run on
the other cores you need to wait for them to reach a scheduling point
on their own.
The test was written to assume that k_thread_wakeup() is synchronous,

Most CPUs have instructions like LOCK, LDREX/STREX, etc which
allows for atomic operations without locking interrupts that
can be invoked from user mode without complication. They typically
use compiler builtin atomic operations, or custom assembly
to implement them.
However, some CPUs may lack these kinds of instructions, such
as Cortex-M0 or some ARC. They use these C-based atomic
operation implementations instead. Unfortunately these require
grabbing a spinlock to ensure proper concurrency with other
threads and ISRs. Hence, they will trigger an exception when
called from user mode.
For these platforms, which support user mode but not atomic
operation instructions, the atomic API has been exposed as
system calls.
Some of the implementations in atomic_c.c which can be instead
expressed in terms of other atomic operations have been removed.
The kernel test of atomic operations now runs in user mode to

Qemu just can't handle 1000 Hz ticks. On our CI machines, CONFIG_HZ
on the host (which is the limit of timing precision for things like
idle wakeups and signal delivery, both of which qemu seems to use for
timing) is 250. When the mismatch gets this large, we start seeing
artifacts like interrupts being delivered "in the past" (i.e. code
sees a z_clock_elapsed() value of "2" ticks before getting a
z_clock_announce() call for "1").
As it happens, this test doesn't actually require timing with that
precision, it just wants "lots of context switching" to exercise the
threadsafety of the mem_pool APIs. So decrease the tick rate to the
100Hz default, but put a loop counter in the worker threads to force
them to do 10x more work, keeping the number of preemptions constant.

The various tests would all do a "wait for threads to exit" step
before checking the results, but this was implemented with a simple
busy wait that turns out to need careful tuning (because there was
busy waiting in the threads).
Rather than try to synchronize this, white box the issue (it's a low
level SMP test, after all) by spinning on the thread states directly
watching for the kernel to flag them dead. The downside here is that
if the process fails for some reason we'll get a hang and a timeout
reported from sanitycheck and not a synchronous ztest assertion. But
in return, successful tests run much faster and I don't need to worry
about how to tune them for IPI latency on different platforms.

This case was predicated on a mistake. The behavior of k_wakeup() has
always been NOT to wake up threads that are "pending" on a wait queue,
only ones blocked on a timeout in k_sleep(). As written, this test
case could never pass.
(Really there's no good reason for that. It seems reasonable to me to
expect wakeup to work symmetrically, and the docs are sort of
ambiguous on the subject. But the code in k_wakeup() is clear:
threads flagged pending get an early exit and the call becomes a

in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

In some circumstances (e.g., a tickless kernel), k_timer_remaining_get()
would not account for time passed that didn't involve clock interrupts.
This adds a simple fix for that, and adds a test case. In addition, the
return value of k_timer_remaining_get() is clamped at 0 in the case of
overdue timers and the API description is adjusted to reflect this.

This test was written to wait on a fifo with a timeout, return, and
check the timing between the start and end using k_cycle_get_32() to
see that it didn't run long. But timeouts expire on tick boundaries,
and so if tick expires between the start of the test and the entry to
k_fifo_get(), the timeout will take one full tick longer than expected
due to aliasing.
As it happened this passed everywhere except nRF (whose cycle timer is
32 kHz and thus more susceptible to coarser aliasing like this), and
even there it passed for a while until the spinlock validation layer
went in and added just enough time to the userspace code paths
(i.e. the code between the start time fetch and the point where the
fifo blocks takes longer) to open the window and push us over the
limit.
The workaround here is just to add a k_sleep(1) call, which is
guaranteed to block and wake up synchronously at the next tick.

Zephyr has always been a uniprocessor system, and its kernel tests are

MISRA rules (see #9892) forbid alloca() and family, even though those
features can be valuable performance and memory size optimizations
useful to Zephyr.
Introduce a MISRA_SANE kconfig, which when true enables a gcc error
condition whenever a variable length array is used.
When enabled, the mempool code will use a theoretical-maximum array
size on the stack instead of one tailored to the current pool
configuration.
The rbtree code will do similarly, but because the theoretical maximum
is quite a bit larger (236 bytes on 32 bit platforms) the array is
placed into struct rbtree instead so it can live in static data (and
also so I don't have to go and retune all the test stack sizes!).
Current code only uses at most two of these (one in the scheduler when
SCHED_SCALABLE is selected, and one for dynamic kernel objects when
USERSPACE and DYNAMIC_OBJECTS are set).
This tunable is false by default, but is selected in a single test (a
subcase of tests/kernel/common) for coverage. Note that the I2C and
SPI subsystems contain uncorrected VLAs, so a few platforms need to be
blacklisted with a filter.

This commit simplifies OS <-> Application interface controlling power

This commit changes this scheme: The sys_suspend() and sys_resume()

The sys_dlist_insert_*() functions had a behavior where a NULL
argument for the insertion position to sys_dlist_insert_after/before()
was interpreted as "the end of the list". We never used that
convention (except in one spot internal to dlist.h which was not
itself used anywhere), and of course already have an API for appending
and prepending to a list.
In practice this was a performance disaster. The NULL check is
virtually never provable statically by the compiler, so that test and
branch is present always. And worse, the check and call to another
function was pushing this beyond the complexity limit for gcc to
inline a function (at -Os optimization anyway), forcing us to use
function calls for what should be a ~8 instruction sequence. The
upshot is that dlist insertions were 2-3x slower than they needed to
be.

Follow Linux in invalidating the link pointers in a removed node. Add

There is actually nothing wrong with this test code idiom. But it's
tickling a qemu emulator bug with the hpet driver and x86_64[1]. The
rapidly spinning calls to k_uptime_get_32() need to disable
interrupts, read timer hardware state and enable them. Something goes
wrong in qemu with this process and the timer interrupt gets lost.
The counter blows right past the comparator without delivering its
interrupt, and thus the interrupt won't be delivered until the counter
is next reset in idle after exit from the busy loop, which is
obviously too late to interrupt the timeslicing thread.
Just replace the loops with a single call to k_busy_wait(). The
resulting code ends up being much simpler anyway. An added bonus is
that we can remove the special case handling for native_posix (which
was an entirely unrelated thing, but with a similar symptom).

This patch adds a x86_64 architecture and qemu_x86_64 board to Zephyr.
Only the basic architecture support needed to run 64 bit code is
added; no drivers are added, though a low-level console exists and is
wired to printk().
The support is built on top of a "X86 underkernel" layer, which can be
built in isolation as a unit test on a Linux host.
Limitations:
+ Right now the SDK lacks an x86_64 toolchain. The build will fall
back to a host toolchain if it finds no cross compiler defined,
which is tested to work on gcc 8.2.1 right now.
+ No x87/SSE/AVX usage is allowed. This is a stronger limitation than
other architectures where the instructions work from one thread even
if the context switch code doesn't support it. We are passing
-no-sse to prevent gcc from automatically generating SSE
instructions for non-floating-point purposes, which has the side
effect of changing the ABI. Future work to handle the FPU registers
will need to be combined with an "application" ABI distinct from the
kernel one (or just to require USERSPACE).
+ Paging is enabled (it has to be in long mode), but is a 1:1 mapping
of all memory. No MMU/USERSPACE support yet.
+ We are building with -mno-red-zone for stack size reasons, but this
is a valuable optimization. Enabling it requires automatic stack
switching, which requires a TSS, which means it has to happen after
MMU support.
+ The OS runs in 64 bit mode, but for compatibility reasons is
compiled to the 32 bit "X32" ABI. So while the full 64 bit
registers and instruction set are available, C pointers are 32 bits
long and Zephyr is constrained to run in the bottom 4G of memory.

The test_timer_periodicity test is racy and subject to initial state
bugs. The operation of that test is to:
1. Start a timer with a known period
2. Take the current time with k_uptime_get()
3. Wait for the timer to fire with k_timer_status_sync()
4. Check that the current time minus start time is the period
But that's wrong, because a tick expiring between any of the first
three steps is going to skew the math (i.e. the timer will have
started on a different tick than the "start time").
And taking an interrupt lock around the process can't fix the issue,
because in the tickless world we live in k_uptime_get() is actually a
realtime quanity based on a hardware counter and doesn't rely on
interrupt delivery.
Instead, use another timer object to synchronize the test start to a
driver tick, ensuring that even if the race is unfixable the initial
conditions are always correct.

k_busy_wait() call used in test expects time in us, but the test
is specifying wait in ms.
Also the test fails on NRF5 platform as the test hardcodes the
interrupts priority to 0 and 1 and assumes system timer to be of
priority 0 which is not the case in NRF5 platforms as per
@pizi-nordic where system timer is at priority 1. Hence changing
test interrupts to 1 and 2.

Rewritten Xtensa CCOUNT driver along the lines of all the other new
drivers. The new API permits much smaller code.
Notably: The Xtensa counter is a 32 bit up-counter with a comparator
register. It's in some sense the archetype of this kind of timer as
it's the simplest of the bunch (everything else has quirks: NRF is
very slow and 24 bit, HPET has a runtime frequency detection, RISC-V
is 64 bit...). I should have written this one first.
Note also that this includes a blacklist of the xtensa architecture on
the tests/driver/ipm test. I'm getting spurious failures there where
a k_sem_take() call with a non-zero timeout is being made out of the
console output code in interrupt context. This seems to have nothing
to do with the timer; I suspect it's because the old timer drivers
would (incorrectly!) call z_clock_announce() in non-interrupt context
in some contexts (e.g. "expiring really soon"). Apparently this test
(or something in the IPM or Xtensa console code) was somehow relying
on that on Xtensa. But IPM is a Quark thing and there's no particular
reason to run this test there.

This test was written with an outrageously long timeout of 25 seconds.
That blows right through the 32 bit cycle counter on qemu_cortex_m3[1]
and produces an essentially random delay instead of the desired
number, causing a hang with the new SysTick driver in tickless mode.
Push the number down so it doesn't overflow. The root cause, though,
is that k_busy_wait() can take arguments it can't handle. It ought to
have an outer loop or something so that it can spin for INT_MAX
milliseconds correctly.

Qemu doesn't like tickless. By default[1] it tries to be realtime as
vied by the host CPU -- presenting read values from hardware cycle
counters and interrupt timings at the appropriate real world clock
times according to whatever the simulated counter frequency is. But
when the host system is loaded, there is always the problem that the
qemu process might not see physical CPU time for large chunks of time
(i.e. a host OS scheduling quantum -- generally about the same size as
guest ticks!) leading to lost cycles.
When those timer interrupts are delivered by the emulated hardware at
fixed frequencies without software intervention, that's not so bad:
the work the guest has to do after the interrupt generally happens
synchronously (because the qemu process has just started running) and
nothing notices the dropout.
But with tickless, the interrupts need to be explicitly programmed by
guest software! That means the driver needs to be sure it's going to
get some real CPU time within some small fraction of a Zephyr tick of
the right time, otherwise the computations get wonky.
The end result is that qemu tends to work with tickless well on an
unloaded/idle run, but not in situations (like sanitycheck) where it
needs to content with other processes for host CPU.
So, add a flag that drivers can use to "fake" tickless behavior when
run under qemu (only), and enable it (only!) for the small handful of
tests that are having trouble.
[1] There is an -icount feature to implement proper cycle counting at
the expense of real-world-time correspondence. Maybe someday we might
get it to work for us.

If the idle code was detecting that it needed to sleep for less than
CONFIG_SYS_TICKLESS_IDLE_THRESH, then it would never call
z_clock_set_timeout() at all, which means that the system would never
wake up unless it already had a timeout scheduled! Apparently we
lacked a test case to detect this condition.
Honestly this seems like a crazy feature to me. There's no benefit in
delivering needless tick announcements. If the system has the
capacity to enter deeper sleep for long timeouts, that's already
exposed via the PM APIs, the timer subsystem needn't be involved.

The system tick count is a 64 bit quantity that gets updated from
interrupt context, meaning that it's dangerously non-atomic and has to
be locked. The core kernel clock code did this right.
But the value was also exposed to the rest of the universe as a global
variable, and virtually nothing else was doing this correctly. Even
in the timer ISRs themselves, the interrupts may be themselves
preempted (most of our architectures support nested interrupts) by
code that wants to set timeouts and inspect system uptime.

The existing API defined sys_clock_{hw_cycles,ticks}_per_sec as simple

were a build constant.
Properly, these should be an API defined by the timer driver (who
controls those rates) and consumed by the clock subsystem. So give
them function syntax as a stepping stone to get there.

Summary: revised attempt at addressing issue 6290. The
following provides an alternative to using
CONFIG_APPLICATION_MEMORY by compartmentalizing data into
Memory Domains. Dependent on MPU limitations, supports
compartmentalized Memory Domains for 1...N logical
applications. This is considered an initial attempt at
designing flexible compartmentalized Memory Domains for
multiple logical applications and, with the provided python
script and edited CMakeLists.txt, provides support for power
of 2 aligned MPU architectures.
Overview: The current patch uses qualifiers to group data into
subsections. The qualifier usage allows for dynamic subsection
creation and affords the developer a large amount of flexibility
in the grouping, naming, and size of the resulting partitions and
domains that are built on these subsections. By additional macro
calls, functions are created that help calculate the size,
address, and permissions for the subsections and enable the
developer to control application data in specified partitions and
memory domains.
Background: Initial attempts focused on creating a single
section in the linker script that then contained internally
grouped variables/data to allow MPU/MMU alignment and protection.
This did not provide additional functionality beyond
CONFIG_APPLICATION_MEMORY as we were unable to reliably group
data or determine their grouping via exported linker symbols.
Thus, the resulting decision was made to dynamically create
subsections using the current qualifier method. An attempt to
group the data by object file was tested, but found that this
broke applications such as ztest where two object files are
created: ztest and main. This also creates an issue of grouping
the two object files together in the same memory domain while
also allowing for compartmenting other data among threads.
Because it is not possible to know a) the name of the partition
and thus the symbol in the linker, b) the size of all the data
in the subsection, nor c) the overall number of partitions
created by the developer, it was not feasible to align the
subsections at compile time without using dynamically generated
linker script for MPU architectures requiring power of 2
alignment.
In order to provide support for MPU architectures that require a
power of 2 alignment, a python script is run at build prior to
when linker_priv_stacks.cmd is generated. This script scans the
built object files for all possible partitions and the names given
to them. It then generates a linker file (app_smem.ld) that is
included in the main linker.ld file. This app_smem.ld allows the
compiler and linker to then create each subsection and align to
the next power of 2.
Usage:
- Requires: app_memory/app_memdomain.h .
- _app_dmem(id) marks a variable to be placed into a data
section for memory partition id.
- _app_bmem(id) marks a variable to be placed into a bss
section for memory partition id.
- These are seen in the linker.map as "data_smem_id" and
"data_smem_idb".
- To create a k_mem_partition, call the macro
app_mem_partition(part0) where "part0" is the name then used to
refer to that partition. This macro only creates a function and
necessary data structures for the later "initialization".
- To create a memory domain for the partition, the macro
app_mem_domain(dom0) is called where "dom0" is the name then
used for the memory domain.
- To initialize the partition (effectively adding the partition
to a linked list), init_part_part0() is called. This is followed
by init_app_memory(), which walks all partitions in the linked
list and calculates the sizes for each partition.
- Once the partition is initialized, the domain can be
initialized with init_domain_dom0(part0) which initializes the
domain with partition part0.
- After the domain has been initialized, the current thread
can be added using add_thread_dom0(k_current_get()).
- The code used in ztests ans kernel/init has been added under
a conditional #ifdef to isolate the code from other tests.
The userspace test CMakeLists.txt file has commands to insert
the CONFIG_APP_SHARED_MEM definition into the required build
targets.
Example:
/* create partition at top of file outside functions */
app_mem_partition(part0);
/* create domain */
app_mem_domain(dom0);
_app_dmem(dom0) int var1;
_app_bmem(dom0) static volatile int var2;
int main()
{
init_part_part0();
init_app_memory();
init_domain_dom0(part0);
add_thread_dom0(k_current_get());
...
}
- If multiple partitions are being created, a variadic
preprocessor macro can be used as provided in
app_macro_support.h:
FOR_EACH(app_mem_partition, part0, part1, part2);
or, for multiple domains, similarly:
FOR_EACH(app_mem_domain, dom0, dom1);
Similarly, the init_part_* can also be used in the macro:
FOR_EACH(init_part, part0, part1, part2);
Testing:
- This has been successfully tested on qemu_x86 and the
ARM frdm_k64f board. It compiles and builds power of 2
aligned subsections for the linker script on the 96b_carbon
boards. These power of 2 alignments have been checked by
hand and are viewable in the zephyr.map file that is
produced during build. However, due to a shortage of
available MPU regions on the 96b_carbon board, we are unable
to test this.
- When run on the 96b_carbon board, the test suite will
enter execution, but each individaul test will fail due to
an MPU FAULT. This is expected as the required number of
MPU regions exceeds the number allowed due to the static
allocation. As the MPU driver does not detect this issue,
the fault occurs because the data being accessed has been
placed outside the active MPU region.
- This now compiles successfully for the ARC boards
em_starterkit_em7d and em_starterkit_em7d_v22. However,
as we lack ARC hardware to run this build on, we are unable
to test this build.
Current known issues:
1) While the script and edited CMakeLists.txt creates the
ability to align to the next power of 2, this does not
address the shortage of available MPU regions on certain
devices (e.g. 96b_carbon). In testing the APB and PPB
regions were commented out.
2) checkpatch.pl lists several issues regarding the
following:
a) Complex macros. The FOR_EACH macros as defined in
app_macro_support.h are listed as complex macros needing
parentheses. Adding parentheses breaks their
functionality, and we have otherwise been unable to
resolve the reported error.
b) __aligned() preferred. The _app_dmem_pad() and
_app_bmem_pad() macros give warnings that __aligned()
is preferred. Prior iterations had this implementation,
which resulted in errors due to "complex macros".
c) Trailing semicolon. The macro init_part(name) has
a trailing semicolon as the semicolon is needed for the
inlined macro call that is generated when this macro
expands.
Update: updated to alternative CONFIG_APPLCATION_MEMORY.
Added config option CONFIG_APP_SHARED_MEM to enable a new section
app_smem to contain the shared memory component. This commit
seperates the Kconfig definition from the definition used for the
conditional code. The change is in response to changes in the
way the build system treats definitions. The python script used
to generate a linker script for app_smem was also midified to
simplify the alignment directives. A default linker script
app_smem.ld was added to remove the conditional includes dependency
on CONFIG_APP_SHARED_MEM. By addining the default linker script
the prebuild stages link properly prior to the python script running

The idea behind this test is to race two CPUs against each other,
validating that each is truly running simultaneously. But it just
assumed that the other thread/cpu would start synchronously as soon as
k_thread_create() returned.
Normally, that works fine. But while debugging I added some code that
was slowing down entry to the other thread (or maybe the return from
k_thread_create() into the main thread) long enough to allow one
thread to get a significant head start. That breaks the logic in the
test and things were inexplicably "failing".
Put a spin loop around the count so that the main thread can start
counting to within the memory system's ability to inform it of the
change from the other thread.

This test exaustively tests preemption points between threads of all
priority classes (cooperative, preemptible, and metairq), done both
from a synchronous reschedule (via k_sem_give() and from interrupt
context (via irq_offload()), and with and without the sched_lock()
held. It then detects the next thread that runs and validates vs. the
documented priority rules.
Note that there is a whitelisted case on ARM, where irq_offload()
seems not to be working like a true interrupt (it always returns to
the interrupted context and doesn't seem to hit the normal exception
return path which can context switch). And native_posix is excluded
because of failures and the fact that it's actually never possible to
truly preempt a thread there (they run to completion inside _Swap()
et. al. and then block themselves). Both of these should be fixable
in the future but don't (seem to) directly relate to this test.

The only difference between this call and k_thread_abort() (beyond
some minor performance deltas) is that "cancel" will act as a noop in
cases where the thread has begun execution and will return an error.
"Abort" always succeeds, of course. That is inherently racy when used
as a "stop the thread" API: there's no way in general (or at all in
SMP situations) to know that you're calling this function "early
enough" to catch the thread before it starts.
Effectively, all k_thread_cancel() gives you that k_thread_abort()
doesn't is an indication about whether or not a thread has started.
There are many other ways to get that information that don't require
dangerous kernel APIs.

The read/write_kernel_stack tests are confusingly named and incorrectly
implemented for ARM; they are intended to test that user mode threads
cannot read or write their privileged stacks. The privileged stacks
on ARM are not relative to the user stack, and thus their location
cannot be computed from the user stack. To find the privileged stack on
ARM, we have to use _k_priv_stack_find(), which we do during setup
in test_main() rather than from the usermode thread itself. Accessing
thread_stack directly from the test function requires making it
non-static in ztest, so we also give it a ztest_ prefix to avoid
collisions with other test programs. Rename the test functions and
global pointer variable to more accurately reflect their purpose.

Add tests of the ability to read or write the stack of another thread.
Use semaphores for explicit synchronization of the start and end of the
other thread to ensure that the attempted stack access occurs while the
thread is alive. This ensures that the MMU/MPU has been configured at
least once to allow userspace access to the stack, and that any
removal of access upon thread termination has not yet occurred. This
therefore should exercise changing the MMU/MPU configuration to remove
access to the other thread's stack when switching back to our
thread.
Tested on qemu_x86 (pass) and on frdm_k64f (with and without the ARM
userspace patches; with them, the tests pass; without, they fail as
expected). Also, as with most of the other tests, if you replace
ztest_user_unit_test() with ztest_unit_test(), then the tests fail as

This is still work-in-progress, but putting it up in case it is
helpful to people working in this area and for early comments.
Add a set of tests to validate the expected security properties
of threads created with K_USER when CONFIG_USERSPACE=y. This can
be used as a regression test for architectures that already implement
this support and as a validation test for others.
I considered incorporating these tests into the existing protection
test, but decided against it since protection does not enable or rely
upon CONFIG_USERSPACE for its existing tests and passes on everything
that provides MPU or MMU support, even without full userspace support.
I also considered incorporating these tests into the existing
obj_validation test, but decided against it since obj_validation only
tests the object validation/permission logic, does not run any user
mode threads (or strictly depend on that support), and passes
on both x86 and arm today, unlike these tests. That said, I have no
strong objections if it would be preferable to fold these into it
(and perhaps rename it to be more general).
The current tests implemented in this test program verify the following
for a thread created with K_USER:
is_usermode: is running in usermode
priv_insn: cannot invoke privileged insns directly
write_control: cannot write to control registers
disable_mmu_mpu: cannot disable memory protections (MMU/MPU)
read_kernram: cannot read from kernel RAM
write_kernram: cannot write to kernel RAM
write_kernro: cannot write to kernel rodata
write_kerntext: cannot write to kernel text
read_kernel_data: cannot read __kernel-marked data
write_kernel_data: cannot write __kernel-marked data
read_kernel_stack: cannot read the kernel/privileged stack
write_kernel_stack: cannot write the kernel/privileged stack
pass_user_object: cannot pass a non-kernel object to a syscall
pass_noperms_object: cannot pass an object to a syscall without a grant
start_kernel_thread: cannot start a kernel (non-user) thread
Some of the tests overlap and could possibly be dropped, but it
seems harmless to retain them. The particular targets of read/write
tests are arbitrary other than meeting the test criteria and can be
changed (e.g. in data, rodata, or text) if desired to avoid coupling
to kernel implementation details that may change in the future.
On qemu_x86, all of the tests pass. And, if you replace all
occurrences of ztest_user_unit_test() with ztest_unit_test(), then
all of the tests fail (i.e. when the tests are run in kernel mode,
they all fail as expected). On frdm_k64f presently (w/o the arm
userspace patches), all of the tests fail except for write_kernro and
write_kerntext, as expected.
ToDo:
- Verify that a user thread cannot access data in another memory domain.
- Verify that a user thread cannot access another thread's stack.
- Verify that a user thread cannot access another thread's kobject.
- Verify that k_thread_user_mode_enter() transitions correctly.
- Verify that k_object_access_revoke() is enforced.
- Verify that syscalls return to user mode upon completion.

The end_sema k_sem was only initialized on one of the several paths
that used it, leading to some crazy clobber-the-run-queue behavior

and the pipe object were made non-static..
Adding a k_sem_init() call fixes the corrupt issue, but really the
right thing is to use the DEFINE macro, so do that instead. Note that
that the initializer changes the linkage order too (by putting the
semaphore in a separate segment), so... yeah, it's actually impossible
to prove that this patch in isolation resolves the issue seen without
manual validation.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.

$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

Avoiding the use of system includes in these cases is beneficial
because;
* The source code will be easier to build because there will be fewer

Currently this is defined as a k_thread_stack_t pointer.
However this isn't correct, stacks are defined as arrays. Extern
references to k_thread_stack_t doesn't work properly as the compiler
treats it as a pointer to the stack array and not the array itself.
Declaring as an unsized array of k_thread_stack_t doesn't work
well either. The least amount of confusion is to leave out the
pointer/array status completely, use pointers for function prototypes,
and define K_THREAD_STACK_EXTERN() to properly create an extern
reference.
The definitions for all functions and struct that use
k_thread_stack_t need to be updated, but code that uses them should
be unchanged.

As luck would have it, the TSS for the main IA task has
all the information we need, populate an exception stack
frame with it.
The double-fault handler just stashes data and makes the main
hardware thread runnable again, and processing of the
exception continues from there.
We check the first byte before the faulting ESP value to see
if the stack pointer had run up to a non-present page, a sign
that this is a stack overflow and not a double fault for
some other reason.
Stack overflows in kernel mode are now recoverable for non-
essential threads, with the caveat that we hope we weren't in
a critical section updating kernel data structures when it
happened.

Historically, stacks were just character buffers and could be treated
as such if the user wanted to look inside the stack data, and also
declared as an array of the desired stack size.
This is no longer the case. Certain architectures will create a memory
region much larger to account for MPU/MMU guard pages. Unfortunately,
the kernel interfaces treat both the declared stack, and the valid
stack buffer within it as the same char * data type, even though these
absolutely cannot be used interchangeably.
We introduce an opaque k_thread_stack_t which gets instantiated by
K_THREAD_STACK_DECLARE(), this is no longer treated by the compiler
as a character pointer, even though it really is.
To access the real stack buffer within, the result of
K_THREAD_STACK_BUFFER() can be used, which will return a char * type.
This should catch a bunch of programming mistakes at build time:
- Declaring a character array outside of K_THREAD_STACK_DECLARE() and
passing it to K_THREAD_CREATE
- Directly examining the stack created by K_THREAD_STACK_DECLARE()
which is not actually the memory desired and may trigger a CPU
exception

Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.

Add a self-protection test suite with a set of tests
to check whether one can overwrite read-only data
and text, and whether one can execute from data,
stack, or heap buffers. These tests are modeled after
a subset of the lkdtm tests in the Linux kernel.
These tests have twice caught bugs in the Zephyr NXP MPU
driver, once during initial testing/review of the code
(in its earliest forms on gerrit, reported to the original
author there) and most recently the regression introduced
by commit bacbea6e21 ("arm: nxp: mpu: Rework handling
of region descriptor 0"), which was fixed by
commit a8aa9d4f3dbbe8 ("arm: nxp: mpu: Fix region descriptor
0 attributes") after being reported.
This is intended to be a testsuite of self-protection features
rather than just a test of MPU functionality. It is envisioned
that these tests will be expanded to cover a wider range of
protection features beyond just memory protection, and the
current tests are independent of any particular enforcement
mechanism (e.g. MPU, MMU, or other).
The tests are intended to be cross-platform, and have been
built and run on both x86- and ARM-based boards. The tests
currently fail on x86-based boards, but this is an accurate
reflection of current protections and should change as MMU
support arrives.
The tests leverage the ztest framework, making them suitable
for incorporation into automated regression testing for Zephyr.

This patch amounts to a mostly complete rewrite of the k_mem_pool
allocator, which had been the source of historical complaints vs. the
one easily available in newlib. The basic design of the allocator is
unchanged (it's still a 4-way buddy allocator), but the implementation
has made different choices throughout. Major changes:
Space efficiency: The old implementation required ~2.66 bytes per
"smallest block" in overhead, plus 16 bytes per log4 "level" of the
allocation tree, plus a global tracking struct of 32 bytes and a very
surprising 12 byte overhead (in struct k_mem_block) per active
allocation on top of the returned data pointer. This new allocator
uses a simple bit array as the only per-block storage and places the
free list into the freed blocks themselves, requiring only ~1.33 bits
per smallest block, 12 bytes per level, 32 byte globally and only 4
bytes of per-allocation bookeeping. And it puts more of the generated
tree into BSS, slightly reducing binary sizes for non-trivial pool
sizes (even as the code size itself has increased a tiny bit).
IRQ safe: atomic operations on the store have been cut down to be at
most "4 bit sets and dlist operations" (i.e. a few dozen
instructions), reducing latency significantly and allowing us to lock
against interrupts cleanly from all APIs. Allocations and frees can
be done from ISRs now without limitation (well, obviously you can't
sleep, so "timeout" must be K_NO_WAIT).
Deterministic performance: there is no more "defragmentation" step
that must be manually managed. Block coalescing is done synchronously
at free time and takes constant time (strictly log4(num_levels)), as
the detection of four free "partner bits" is just a simple shift and
mask operation.
Cleaner behavior with odd sizes. The old code assumed that the
specified maximum size would be a power of four multiple of the
minimum size, making use of non-standard buffer sizes problematic.
This implementation re-aligns the sub-blocks at each level and can
handle situations wehre alignment restrictions mean fewer than 4x will
be available. If you want precise layout control, you can still
specify the sizes rigorously. It just doesn't break if you don't.
More portable: the original implementation made use of GNU assembler
macros embedded inline within C __asm__ statements. Not all
toolchains are actually backed by a GNU assembler even when the
support the GNU assembly syntax. This is pure C, albeit with some
hairy macros to expand the compile-time-computed values.
Related changes that had to be rolled into this patch for bisectability:
* The new allocator has a firm minimum block size of 8 bytes (to store
the dlist_node_t). It will "work" with smaller requested min_size
values, but obviously makes no firm promises about layout or how
many will be available. Unfortunately many of the tests were
written with very small 4-byte minimum sizes and to assume exactly
how many they could allocate. Bump the sizes to match the allocator
minimum.
* The mbox and pipes API made use of the internals of k_mem_block and
had to be ported to the new scheme. Blocks no longer store a
backpointer to the pool that allocated them (it's an integer ID in a
bitfield) , so if you want to "nullify" them you have to use the
data pointer.
* test_mbox_api had a bug were it was prematurely freeing k_mem_blocks
that it sent through the mailbox. This worked in the old allocator
because the memory wouldn't be touched when freed, but now we stuff
list pointers in there and the bug was exposed.
* Remove test_mpool_options: the options (related to defragmentation
behavior) tested no longer exist.

Currently, a queue/fifo getter chooses how long to wait for an
element. But there are scenarios when putter would know better,
there should be a way to expire getter's timeout to make it run
again. k_queue_cancel_wait() and k_fifo_cancel_wait() functions
do just that. They cause corresponding *_get() functions to return
with NULL value, as if timeout expired on getter's side (even
K_FOREVER).
This can be used to signal out of band conditions from putter to
getter, e.g. end of processing, error, configuration change, etc.
A specific event would be communicated to getter by other means
(e.g. using existing shared context structures).
Without this call, achieving the same effect would require e.g.
calling k_fifo_put() with a pointer to a special sentinal memory
structure - such structure would need to be allocated somewhere
and somehow, and getter would need to recognize it from a normal
data item. Having cancel_wait() functions offers an elegant
alternative. From this perspective, these calls can be seen as
an equivalent to e.g. k_fifo_put(fifo, NULL), except that such
call won't work in practice.

That was an oversight that should not have caused any problem. However,

Current users of sys_bitfield*() are bending over backwards to cast
what is most of the times a pointer into an integer.
Bitfields can be better described with an void *, so
uint{8,16,32,64}_t or any other container can be used. Most
sys_bitfield*() operations, by extension, can do the same. Note void *
has byte arithmetic, like char *.
This change will also make it implicit, for any future split of the
address space between virtual (what the SW is seeing) and physical
(what the HW is seeing) way clearer, as the functions dealing with
physical, non directly referentiable/mappeable addreses to use an
integer type, like mem_addr_t.
- include/arch/ARCH/*asm_inline*:
- sys_bitfield*() all modified to take 'void *'
Note 'void *' arihtmethic is byte based, which makes some things
easier.
- include/sys_io.h:
- introduces DEFINE_BITFIELD
- update docs
- tests/kernel/bitfield: remove all the cast contortions, use DEFINE_BITFIELD
PENDING: update other TCs
- include/arch/nios/nios2.h, drivers/interrupt_controller/ioapic_intr.c:

except in cases of 32-bit integer overflow. Enforce this with a

We also check that the number of cycles elapsed after sleeping for 1

that use different timer sources for the system clock and timestamps.

Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu. Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom. Do not present pseudo generators if a true random generator
is presented.
This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.
In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.
Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

Revises the test to account for changes in LIFO object behavior
in the unified kernel.
Note: A LIFO object shouldn't really be used to try and pass
data items between two different threads in an ordered manner,
as this test is doing. Ordered behavior should only be expected
when a single thread is adding and removing items from a LIFO.
A LIFO is typically used to pass data items between different
threads when ordering doesn't matter -- for example, when using the
LIFO to implement a shared pool of data items that can be allocated
and returned by a bunch of threads. (A LIFO object is more efficient
than a FIFO object for implementing this kind of pool.)

Binutils ld has an annoying misfeature (apparently a regression from a
few years ago) that alignment directives (and alignment specifiers on
symbols) apply only to the runtime addresses and not, apparently, to
the load address region specified with the "AT>" syntax. The net
result is that by default the LMA output ends up too small for the
addresses generated in RAM. See here for some details:
https://sourceware.org/ml/binutils/2013-06/msg00246.htmlhttps://sourceware.org/ml/binutils/2014-01/msg00350.html
The required workaround/fix is that AFAICT any section which can have
inherit a separate VMA vs. LMA from a previous section must specify an
"ALIGN_WITH_INPUT" attribute. Otherwise the sections will get out of
sync and the XIP data will be wrong at runtime.
No, I don't know why this isn't the default behavior.
A further complexity is that this feature only works as advertised
when the section is declared with the "AT> region" syntax after the
block and not "AT(address)" in the header. If you use the header
syntax (with or without ALIGN_WITH_INPUT), ld appears to DOUBLE-apply
padding and the LMA ends up to big. This is almost certainly a
binutils bug, but it's trivial to work around (and the working syntax
is actually cleaner) so we adjust the usage here.
Note finally that this patch includes an effective reversion of commit
d82e9dd9 ("x86: HACK force alignment for _k_task_list section"), which
was an earlier workaround for what seems to be the same issue.

nanokernel. However, tcs.prio can be written to and this works without
issues. On unified kernel, this does not work however because the
thread has to move between linked lists representing each priority in
the ready queue.

Previously, exception stubs had to be declared in assembly
language files. Now we have two new APIs to regsiter exception
handlers at C toplevel:
_EXCEPTION_CONNECT_CODE(handler, vector)
_EXCEPTION_CONNECT_NOCODE(handler, vector)
For x86 exceptions that do and do not push error codes onto
the stack respectively.
In addition, it's now no longer necessary to #define around
exception registration. We now use .gnu.linkonce magic such that
the first _EXCEPTION_CONNECT_*() that the linker finds is used
for the specified vector. Applications are free to install their
own exception handlers which will take precedence over default
handlers such as installed by arch/x86/core/fatal.c
Some Makefiles have been adjusted so that the default exception
handlers in arch/x86/core/fatal.c are linked last. The code has
been tested that the right order of precedence is taken for
exceptions overridden in the floating point, gdb debug, or
application code. The asm SYS_NANO_CPU_EXC_CONNECT API has been
removed; it was ill- conceived as it only worked for exceptions
that didn't push error codes. All the asm NANO_CPU_EXC_CONNECT_*
APIs are gone as well in favor of the new _EXCEPTION_CONNNECT_*()
APIs.
CONFIG_EXCEPTION_DEBUG no longer needs to be disabled for test
cases that define their own exception handlers.

We have already done this on x86 and ARM. The policy is as follows:
* IRQ priority levels starting at 0 all have the same semantics and
do not have special properties. The priority level is either ignored
on arches which do not support programmable priority levels, or lower
priority levels take precedence over higher ones.
* Special-case priorty levels are specified via flags, in which case
the supplied priority level is ignored.

Having two parallel implementations is a maintenance issue, especially
when some strategically placed #ifdefs will suffice.
We prefer the ASM versions for SYS V, as we need complete control of
the emitted assembly for interrupt handling and context switching.
The SYS V code is far more mature. IAMCU C code has known issues with
-fomit-frame-pointer.
The only difference between the two calling conventions is that the
first three function arguments are provided in eax, edx, ecx instead
of on the stack.

We now allow use of -mgpopt=global and -mgpopt=data. The 'global'
option is now the default instead of compiler-default local, expanding
global pointer usage to all small data in the system.
For systems where all RAM is less than 64K, the 'data' option may be
appropriate.
Some fixes had to be made to the system in order to get around some
issues:
* prep_c.c no longer uses fake linker variables to figure out the size
of data or BSS, as these gave the linker fits as it tried to compute
relative addresses to them.
* _k_task_ptr_idle is create by sysgen and placed in a special section.
Any small data in a special section needs to be declared extern
with __attribute__((section)) else the compiler will assume it's in
.sdata.
* same situation with extern references to k_pipe_t (fixed pipe_priv
test)
For legacy applications being ported to Nios II which do things that
freak out global pointer calculation, it can be disabled entirely.
