When in Sharing Floating Point Services mode we want to
dynamically save and restore the FP registers in thread
context switch, depending on whether the swapped-in and
swapped-out threads are currently using the FP registers.
This commit adds this functionality to the ARM context
switch mechanism. The logic consists of inspecting the
corresponding status flag (present in thread.arch.mode)
to decide whether to save or restore the FP registers.

Only a single bit of the 4-byte internal (thread.arch) status
variable 'mode' is currently used, when we build with User mode
support (CONFIG_USERSPACE=y). In this commit we extend the usage
of 'mode' variable, adding an additional bit-flag to track the
status of the floating point context in a particular thread,
i.e. to track whether FP context is active or not. The status
bit is meant to be used in context-switch, to restore the FP
register context when required.

The initial carved stack frame only needs to contain the basic
stack frame (state context), because:
- under No/Unshared FP Services mode no FP context is stacked.
- under FP Sharing mode FP context is cleared upon thread
creation.
This commit removes the unnecessary stacking of the FP context
during thread initialization. This results in reduced stack
usage under the Shared FP Services mode (CONFIG_FP_SHARING=y).
Also, we do not need to initialize the FPSCR, because there is
no FP stack frame carved.

In FP Sharing mode we enable both automatic and lazy state
preservation of the FP context. This configuration improves
interrupt latency. Under this configuration the FP registers
will only be stacked when the thread is swapped out during
context-switch. Before jumping to main() we clear the FPCA
flag of the CONTROL register, so the FP context can be used
by the main thread.

on non-XIP system, SRAM is the default region, and relocated .data
section and .bss section of SRAM shouldn't be inserted between
_image_rom_start and _image_rom_end, because the memory region between
_image_rom_start and _image_rom_end will construct the mpu ro region.
Also for the newly added memory region on non-XIP system, the
relocated .text secition and .rodata section should also be mpu aligned.

This commit consolidates the temperature conversion into a single
location and subtracts the bias from the measurement using values from
the datasheet. Also magic numbers have been replaced with more
descriptive macros.
Signed-off-by: Brett Witherspoon <spoonb@cdspooner.com>
This driver uses magic numbers which are incorrect. A correct conversion
is done using the LSB/g scale factors given by Table 1 in the
specifications section of the ADXL362 (Rev. F) datasheet. The entire
conversion has also been consolidated into a signal function.
The sensitivity and offset of the accelerometer values actually vary
with the supply voltage and temperature. Using datasheet provided values
for 25 C and 2.0 V is the best we can do. Users will need to apply
sensitivity and offset corrections for their application.

We generated some alias defines for children of a bus in which we had a

When Zephyr crashes immediately QEMU reports an error immediately. This
is immediately reported by "make run". Then sanitycheck points the user
at the output of "make run". However the error message(s) are in QEMU's
output which is in a different .log file.
To address this situation point the error message at handler.log
instead of run.log if and only if handler.log is not empty.
To reproduce here's an artificial but very simple crash:
sanitycheck --extra-args=CONFIG_TEST_USERSPACE=n \
-p qemu_x86 -T tests/kernel/mem_protect/stackprot/

Previous version calculated rt_clock_base incorrectly by subtracting
clock_gettime from the specified time. Effectively the following
formula was used.
rt_clock_base := new_time - clock_gettime()
This is clearly incorrect when we consider what should happen if we
call clock_settime with the result of clock_gettime. It ought to be
approximately a no-op, but instead we end up zeroing the clock.
rt_clock_base := clock_gettime() - clock_gettime() = 0
This patch fixes clock_settime by instead using k_uptime_get to
calculate rt_clock_base, like so:
rt_clock_base := new_time - k_uptime_get()
Trying the earlier thought experiment we get:
rt_clock_base := clock_gettime() - k_uptime_get()
Using the definition of clock_gettime this expands to:
rt_clock_base := (rt_clock_base + k_uptime_get()) - k_uptime_get()
The two k_uptime_get() terms cancel out, leaving:
rt_clock_base := rt_clock_base
I.e. the no-op that we expect when calling clock_settime with
the result of clock_gettime.
Note: The bug is only observable when rt_clock_base is non-zero.
So when clock_settime is called for the first time, it will appear
to work correctly since rt_clock_base is initialized to 0.
