Ioannis Glaropoulos a7a4c89579 bluetooth: controller: conditionally define NRF_RADIO_TXPOWER_POS4DBM
nRF5340 does not support a Radio TX power of 4dBm, so we
introduce a dependency for the respective Kconfig option
for TX power, so the option is never defined for nRF5340.

The Company ID concept is not restricted to the controller, and should

Ioannis Glaropoulos 73483094da bluetooth: controller: nrf5: simplify preprocessor conditionals
We make a minor simplification in the way we define
RADIO_PDU_LEN_MAX in Nordic nRF LE radio driver; as
nRF51 SoC series is the only series where the LL PDU
max length representation is limited to a 5-bit field,
we simplify the conditional preprocessor expression,
to avoid having to list all nRF5x SoCs with PDU LEN
MAX is represented by an 8-bit integer field.

In addition, we modify the preprocessor conditional,
that compiles in the CCM support for 8-bit length field,
PDUs to be an #ifndef CONFIG_SOC_SERIES_NRF51X, instead
of #ifdef CONFIG_SOC_COMPATIBLE_NRF52X; this will
simplify the expression when adding nRF53X series
support.

Fix ticker previous slot value with elapsed ticks value from

Vinayak Kariappa Chettimada aa38b2298c Bluetooth: controller: split: Fix for Tx Buffer Overflow error
When more than one simultaneous connections are active,
transmitting data packets to peer, a termination causes
host to use the flushed pending number of completed packets
count for other active connections. This is on reception
of HCI disconnection complete event. But the controller has
not yet released any of the pending enqueued Tx buffers
which was happening after the disconnection event was
dispatched to HCI layer.

The fix here is to dispatch the disconnection complete event
from the LLL context after pending Tx buffers have been
flushed and the buffers get returned to Tx pool in the ULL
context. This way buffers are in the Tx pool before host
get to process the disconnection complete event.

considers discardable. Examples of such events could be e.g.
Advertising Reports. The benefit of having such a pool means that the
if there is a heavy inflow of such events it will not cause the
allocation for other critical events to block and may even eliminate
deadlocks in some cases.

Also update all mesh samples not to specify explicit RX buffer counts
anymore. Instead, create appropriate defaults in Kconfig so that we

This event is a priority one, so it's not safe to have it use the RX

advertising events). Since the event is consumed synchronously it's
safe to have a single-buffer pool for it. Also introduce a new
bt_buf_get_evt() API for HCI drivers to simplify the driver-side code,
this effectively also deprecates bt_buf_get_cmd_complete() which now
has no in-tree HCI driver users anymore.

mem_pdu_rx is not runtime resized meaning PDU_RX_SIZE_MIN is no longer
relevant.

Dynamic resizing was a left-over from the old bt controller.
Its size field was only ever set to PDU_RX_SIZE_MIN.
PDU_RX_SIZE_MIN only accounted for advertise PDUs.
So we remove size field from mem_pdu_rx.

However, the rest of the BT controller expects to be able to pull
RX_CNT-number of valid nodes from the pool at init/reset (rx_alloc)
time. This will fail unless we inflate the capacity by one.

To avoid inflation-by-one, mem_* would have to be rewritten to avoid
always-one-extra pattern.

There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when

This is because there are actual C++ functions called min and max

By changing the macros to UPPERCASE, which is consistent with almost all

All files that use these macros have been updated.

Vinayak Kariappa Chettimada 1475402d41 Bluetooth: controller: Introduce ULL LLL architecture
This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.

This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.

The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.

In simulation with the POSIX arch a WFE was added to avoid that

But this function is called with the ECB interrupts disabled.
In normal builds other interrupts will awake the CPU very soon
after entering into that WFE, and the problem was not discovered.

But, in controller only builds, during some conformance tests,
the loop will hang as no other interrupts are coming.

of the freely programmable ones that are used currently. This commit
makes such replacements where possible so that the universal channels
can be left available for other purposes.

This commit also removes macros used previously in calls to functions
enabling and disabling particular PPI channels (as it is sufficient
to use the BIT macro to set bits corresponding to the channel numbers)
to prevent such problems like the one introduces by commit
9d1ca9c390 (channel 18 changed to 17
but the related macro definition not updated).

Sebastian Bøe 5e23278bab Bluetooth: Controller: Use a different flag for speed optimization
The bluetooth controller has been using the flag '-Ofast' to keep
within a real-time limit. There are two problems with this; firstly,
when a project should be optimized for size it is standard to use -O2,
not -Ofast.

Secondly, optimization flags have been deemed to be non-portable, so
instead of directly using "-Ofast" we should use the intent-macro
OPTIMIZE_FOR_SPEED_FLAG to ensure toolchain portability.

Testing has shown that we are still within the real-time limit when
changing from -Ofast to -O2. -Ofast is about 1us and 1% faster, but
increases the code size by 13kB (5% of the available flash on a
nRF51).

Since the slowdown is comparatively small compared to the code size
increase we have decided to use -O2 in place of -Ofast.

Other optimization combinations were also measured and their results
can be seen below:

-Ofast in BLE Controller and in #pragma in entropy driver.
