There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such

The ARM Cortex-M 321 application note is stressing that if

requirement to add barrier instructions after disabling
interupts. However, in ARMv7-M (and ARMv8-M Mainline) we use
BASEPRI, instead. Therefore, if we need the effect of disabling
interrupts to be recongnized immediately we should add barrier
instructions. This commit adds DSB and ISB barriers when
disabling interrupt using BASEPRI in the generic

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
prove that this works.

If CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT is enabled,

due to the need for padding.
For example, tests/subsys/jwt and board mps2_an385:
z_test_mem_partition: addr 0x20000000, size 52
z_libc_partition : addr 0x20000040, size 4
k_mbedtls_partition : addr 0x20008000, size 32736
ending at 0x2000ffff, taking up 65536 bytes
With power-of-two size and alignment requirement,
k_mbedtls_partition takes up 32KB memory and needs to be
aligned on 32KB boundary. If the above partitions are
ordered as shown, there needs to be a lot of padding
after z_libc_partition before k_mbedtls_partition can
start. In order to minimize padding, these partitions
need to be sort by size in descending order.
After the changes here, the partitions are:
k_mbedtls_partition : addr 0x20000000, size 32736
z_test_mem_partition: addr 0x20008000, size 52
z_libc_partition : addr 0x20008040, size 4

There was a detected user error in the code where racing insertions of
k_delayed_work items into different queues would be detected and
flagged as an error (honestly I don't see much value there -- Zephyr
doesn't as a general rule protect against errors like this, and
work_q's are inherently kernel things that don't require
userspace-style checking).
This got broken with spinlockification, where each work_q object got
its own lock, so the single lock wouldn't protect against the other
insert function any more. As it happens, that was needless. The core
synchronization on a work_q is in the internal k_queue object anyway
-- the lock in this file was only ever used for (very fast,
noncontending) delayed work insertion. So go back to a global lock to
preserve the original behavior.

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.

The spinlock validation isn't super lightweight -- it adds only a few
tens of bytess per call, but there are a LOT of locking calls. On
smaller platforms with 32kb of flash, we're bumping into code size
limits on the bigger tests (tests/kernel/poll is a particular
offender).
Check the declared flash size before enabling it.

This adds another helper macro called BT_GATT_CCC_MANAGED which can be
used to set 2 new callbacks:
- cfg_write: Which application can set if it wants to manage writes to
CCC configuration.
- cfg_match: Which application can set if it wants to manage matching
CCC configuration when notifying/indicating.
BT_GATT_CCC_MANAGED retains the ability of saving peer configuration
on storage making it useful for clients which are only interrested in
managing the CCC configuration but not the storage itself.

In case newlib is enabled, but POSIX subsys isn't, there're adhoc
implementations of read() and write() which work only with adhoc
stdin/stdout emulation layer. These are backed by system calls named
like "read" and "write". Rename all these functions and syscalls to
explicitly mention stdin/stdout in the names, to free namespace
for the implementation of generic read/write syscalls which will
integrate with POSIX fdtable.

The phrase 'low power state' is often incorrectly used to indicate
'low power' or 'deep sleep' states. This commit fixes the ambiguities
by renaming 'low power state' to 'power state' where necessary.

CPU_LPS_n name used to indicate a low power state is cryptic and
incorrect. The low power states act on the whole SoC and not exclusively
on the CPU. This patch renames CPU_LPS_n states to LOW_POWER_n. Also
HAS_ pattern for Kconfig options is used in favor of a non standard
_SUPPORTED. Naming of deep sleep states was adjusted accordingly.
Following is a detailed list of string replacements used:
s/SYS_POWER_STATE_CPU_LPS_(\d)_SUPPORTED/HAS_STATE_LOW_POWER_$1/
s/SYS_POWER_STATE_CPU_LPS_(\d)/SYS_POWER_STATE_LOW_POWER_$1/
s/SYS_POWER_STATE_DEEP_SLEEP_(\d)_SUPPORTED/HAS_STATE_DEEP_SLEEP_$1/

Some older variants of newlib (like what we have on xtensa or riscv in
SDK 0.9.5) define timespec and itimerspec in sys/types.h. The timespec
can be handled by a check of __timespec_defined. However itimerspec
doesn't have anything similar so we have to do it by newlib version

Instead of having to enable ramfunc support manually, just make it
transparently available to users, keeping the MPU region disabled if not
used to not waste a MPU region. This however wastes 24 bytes of code
area when the MPU is disabled and 48 bytes when it is enabled, and
probably a dozen of CPU cycles during boot. I believe it is something
acceptable.
Note that when XIP is used, code is already in RAM, so the __ramfunc
keyword does nothing, but does not generate an error.

The linker file defines the __ramfunc_ram_size symbols to get the size

Both SDK 0.10.0-beta2 and the ARM gcc 2018q2 run into a build issue with
newlib and conflict definitions of mode_t type.
First we need to add some ifdef protection if mode_t is already defined
and set _MODE_T_DECLARED if we are the first to define it.
Secondarily, we rename include/posix/sys/types.h to
include/posix/posix_types.h so that we aren't getting a name collusion
with the system sys/types.h and that we can easily and clearily include
it (which we need to do to pull in the info from newlib).

This patch removes the free space calculation from nvs initialization.
The available space can be calculated if required using the routine
nvs_calc_free_space.
This patch also removes the locked state of nvs, it is not possible to
get in a locked state.
This patch adds an extra check on the sector_size configuration and only
allows operation on nvs when nvs has been initialized.
This patch also solves issue #13369, the usage of FLASH_ERASE_BLOCK_SIZE
has been replaced with the flash page api.
Changes:
Removed locked state and free_space from the nvs structure.
nvs_reinit(): has been replaced with by an internal only function
_nvs_startup().
nvs_write(): removed the possibility to place the file system in a
locked state, if to many gc operations are required it will return
-ENOSPC.
ssize_t nvs_calc_free_space(): introduced, calculates the free space
that is available in the nvs file system.
Removed define LOG_LEVEL.
