Start using the upstream Kconfig from LVGL and move the glue code out
of the zephyr tree and put it under lvgl/zephyr/ in modules.
Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@huawei.com>
This updates the lvgl in-tree glue code to work with version v8.1.0 and
bumps the west manifest accordingly.
The following are the most significant changes:
- The logging callback has changes in lvgl and no longer provides the
caller with an integer log level code. We now need to parse the log
string's prefix to determine the level.
- Several Kconfig options (mostly for default values of various settings)
have been removed because these values are no longer configurable in
lvgl.
- The library no longer performs a deep copy of the display and input
device driver structs, so these must no longer be allocated on the
stack in the init func.
Other than that it's mostly about renaming of various structures and
functions and adjusting the calls if function's signatures have changed.
This patch allows all in-tree users to work correctly but it's likely
it doesn't support all new widgets and layouts added in lvgl v8. These
however can be added gradually once this is upstream.

In order to support lvgl v8, we need to provide a realloc() implementation
in our custom sys_heap allocator. This uses sys_heap_realloc() internally
and exposes traditional realloc() semantics.

Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@huawei.com>
Current lvgl code allows to use the kernel heap for dynamic memory
allocation. The k_heap API doesn't however provide k_realloc() which
will be needed in order to update lvgl to v8. Nico suggested there's
no good reason for lvgl to use k_heap and it should stick to either
the libc's allocator or depend on its own private sys_heap.
The alternative would be to extend the k_heap API to provide k_realloc()
but this may be tricky for several reasons and for now there would
be a single user anyway.
This removes the choice of using k_heap for lvgl and renames the user
pool to SYS_HEAP in Kconfig and makes it the default option.
The prj.conf for the lvgl sample is modifed to specify the number of
memory pool blocks instead of the total size as the default block
size is 2048 and it results in the same size of memory.

Added locking to posix read(), write(), close()

In read() missing lock would create uneven calls to locking
mechanism in sockets.c after k_condvar_wait().
That results in socket lock not ever being unlocked

It was noted that `pthread_cond_wait()` would always return
ETIMEDOUT, even when successful (and no timeout should ever
occur with `K_FOREVER`).
The z_sched_wake() / z_sched_wake_all() / z_sched_wait() API
are used here with a swap return value of 0 to indicate

As described in #42403, there was an issue with the existing crc16_ansi()
implementation, since it was not calculating the CRC-16-ANSI (aka
CRC-16-MODBUS). This is because the existing crc16() function only
supported non-reflected input and output (and the CRC-16-ANSI requires
reflection on both) and also it did not seem to support correctly inial
seeds different from 0x0000 (and, again, the CRC-16-ANSI requires 0xffff
as an initial seed).
This commit replaces the existing crc16() with a functional pair,
crc16() and crc16_reflect(), that also work with any poly, any initial seed
and allow to select whether reflection is performed.
It also adapts crc16_ansi() so that it actually returns the correct CRC.
Fixes#42403.

MIPS (Microprocessor without Interlocked Pipelined Stages) is a
instruction set architecture (ISA) developed by MIPS Computer
Systems, now MIPS Technologies.
This commit provides MIPS architecture support to Zephyr. It is
compatible with the MIPS32 Release 1 specification.
Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com>
It's not uncommon to have Zephyr running in environments where it
shares a memory bus with a foreign/non-Zephyr system (both the older
Intel Quark and cAVS audio DSP systems share this property). In those
circumstances, it would be nice to have a utility that allows an
arbitrary-sized chunk of that memory to be used as a unidirectional
buffered byte stream without requiring complicated driver support.
sys_winstream is one such abstraction.
This code is lockless, it makes no synchronization demands of the OS
or hardware beyond memory ordering[1]. It implements a simple
file/socket-style read/write API. It produces small code and is high
performance (e.g. a read or write on Xtensa is about 60 cycles plus
one per byte copied). It's bidirectional, with no internal Zephyr
dependencies (allowing it to be easily ported to the foreign system).
And it's quite a bit simpler (especially for the reader) than the
older cAVS trace protocol it's designed to replace.
[1] Which means that right now it won't work reliably on arm64 until
we add a memory barrier framework to Zephyr! See notes in the code;
the locations for the barriers are present, but there's no utility to
call.

This adds similar ability of sys_multi_heap to the memory blocks
allocator, where a choice function can be used to select
which allocator (of a group) is used for memory block allocation.
Signed-off-by: Daniel Leung <daniel.leung@intel.com>
This introduces yet another memory blocks allocator where:
() All memory blocks have a single fixed size.
() Multiple blocks can be allocated or freed at the same time.
() A group of blocks allocated together may not be contiguous.
This is useful for operations such as scatter-gather DMA
transfers.
() Bookkeeping of allocated blocks is done outside of
the associated buffer (unlike memory slab). This allows
the buffer to reside in memory regions where these can be
powered down to conserve energy.

However, referencing these global variables directly is not thread
safe. In order to get the state of the getopt function for the thread
that is currently using it, call: getopt_state_get();
