Tristan Honscheid 082ca85b7c ztest: bug: Add friendly name helper function for all phases
The `handle_signal()` function in the new ztest API (`ztest_new.c`) uses
an array of strings to lookup a friendly name for each test phase, but
the array only has three elements despite there being six test phases.
This can lead to an out-of-bounds issue. Replace the array with a helper
function and switch statement.

Enjia Mai 2b1bccde07 tests: testsuite: add emulating send IPI in X2APIC mode
We emulate the interrupt by sending the IPI to core itself by
the local APIC for x86 platfrom.

But in X2APIC mode, this no longer works. So we emulate the
interrupt the by writing the IA32_X2APIC_SELF_IPI MSR to send
IPI to the core itself via LOAPIC also. According to SDM vol.3
chapter 10.12.11.

Andy Ross adc901aa6a subsys/ztest: Make 1cpu tests run on CPU 0 specifically
Some hardware has "interesting" configuration like asymmetric default
interrupt masking (the intel_adsp devices in particular, but x86's
IO-APIC driver has tripped over this in the past too) that needs
special treatment if you want to run something on "core 1"
specifically, and 1cpu test cases pretty much by definition are going
to have been written without SMP details in mind.  Switch the logic
around a tiny bit such that these test cases always run on CPU ID zero
explicitly.

Actually in practice this was ALMOST guaranteed to be true already,
because test setup and happens serially, having been started on the
main thread, which starts on CPU 0 by definition.  Then the test
teardown aborts all the spawned threads that might have been running
on CPUs 1+, so those reach idle, and the next test case starts
syncronously on the same thread (and thus CPU) where it started.  But
nonetheless that wasn't actually enforced, and we've found at least
one simulation environment where timing conspires to break things.

Yuval Peress ab1caef8c3 ztest: Update ztest with more powerful testing APIs
1. Test suites in prior ztest serve no purpose other than logical
ordering of tests into a named-group. Move the construct of setup and
teardown into the test suite and away from individual tests.
Additionally, add the constructs of before/after to the test suites.
This model more closely resembels other testing frameworks such as gTest
and Junit.
2. Test can be added to a suite by using ZTEST() or ZTEST_F() where _F
stands for fixture. In the case where _F is used, the argument `this`
will be provided with the type `struct suite_name##_fixture*`. Again,
this models other modern testing frameworks and allows the test to
directly access the already set up data related to the test suite.
3. Add the concept of test rules (from Junit). Rules are similar to the
before/after functions of the test suites but are global and run on all
suites. An example of a test rule can be to check that nothing was
logged to ERROR. The rule can cause the test to fail if anything was
logged to ERROR during an integration test. Another example would be a
rule that verifies that tests ran within some defined timeout.

Yuval Peress dee79d2b66 ztest: Add register functionality
Add new functionality to ztest to improve test modularity. The two
primary new entry points are:
* ztest_register_test_suite
* ztest_run_registered_test_suites

When registering a new test suite, users provide the name as well as
an optional predicate used to filter the tests for each run. Using NULL
as the predicate ensures that the test is run exactly once (after which
it is automatically filtered from future runs).

Calls to ztest_run_registered_test_suites take a state pointer as an
argument. This allows the the pragma functions to decide whether the
test should be run.

The biggest benefit of this system (other than the ability to filter
tests and maintain a larger test state) is the ability to better
modularize the test source code. Instead of all the various tests
having to coordinate and the main function having to know which tests
to run, each source file manages registering its own test
suite and handling the conditions for running the suite.

Nicolas Pitre f1f63dda17 arm64: FPU context switching support
This adds FPU sharing support with a lazy context switching algorithm.

Every thread is allowed to use FPU/SIMD registers. In fact, the compiler
may insert FPU reg accesses in anycontext to optimize even non-FP code
unless the -mgeneral-regs-only compiler flag is used, but Zephyr
currently doesn't support such a build.

It is therefore possible to do FP access in IRS as well with this patch
although IRQs are then disabled to prevent nested IRQs in such cases.

Because the thread object grows in size, some tests have to be adjusted.

Paul Sokolovsky 92ba428626 testsuite: Factor out suite header/footer to tc_util.h
We have a few remaining tests where ztest module is not used directly,
and instead lower-level tc_util.h is used (where ztest also uses that
header). Supposedly, there're good reasons for that. However, tc_util.h
tests have output which is somewhat inconsistent with ztest output,
which may be a problem with automated parsing of test results, e.g. in
CI systems.

So, factor out code to mark testsuite start/end from ztest.c to
tc_util.h as TC_SUITE_START() and TC_SUITE_END() macros, to allow
tc_util.h based tests to produce output fully consistent with
ztest, while avoiding duplicate of code. TC_SUITE_END() accepts
result code (TC_PASS/TC_FAIL), similar to existing TC_END_REPORT().

Andrew Boie acda9bf9ce linker-tool-gcc: revise for MMU support
We need to do a few things differently if we are to support
a virtual memory map, i.e. CONFIG_MMU where CONFIG_KERNEL_VM_BASE
is not the same as CONFIG_SRAM_BASE_ADDRESS.

 - All sections must be specified with a VMA and LMA, where
   VMA is the virtual address and LMA is the physical memory
   location.
 - All sections must be specified with ALIGN_WITH_INPUT to
   keep VMAs and LMAs synchronized

To do this, the existing linker macros need some adjustment:

 - GROUP_LINK_IN undefined when CONFIG_KERNEL_VM_BASE is not
   the same as CONFIG_SRAM_BASE_ADDRESS.
 - New macro GROUP_ROM_LINK_IN for text/rodata sections
 - New macro GROUP_NOLOAD_LINK_IN for bss/noinit sections
 - Implicit ALIGN_WITH_INPUT for all sections

GROUP_FOLLOWS_AT is unused anywhere in the kernel for years
now and has been removed.

Andrew Boie b0c155f3ca kernel: overhaul stack specification
The core kernel computes the initial stack pointer
for a thread, properly aligning it and subtracting out
any random offsets or thread-local storage areas.
arch_new_thread() no longer needs to make any calculations,
an initial stack frame may be placed at the bounds of
the new 'stack_ptr' parameter passed in. This parameter
replaces 'stack_size'.

thread->stack_info is now set before arch_new_thread()
is invoked, z_new_thread_init() has been removed.
The values populated may need to be adjusted on arches
which carve-out MPU guard space from the actual stack
buffer.

thread->stack_info now has a new member 'delta' which
indicates any offset applied for TLS or random offset.
It's used so the calculations don't need to be repeated
if the thread later drops to user mode.

CONFIG_INIT_STACKS logic is now performed inside
z_setup_new_thread(), before arch_new_thread() is called.

thread->stack_info is now defined as the canonical
user-accessible area within the stack object, including
random offsets and TLS. It will never include any
carved-out memory for MPU guards and must be updated at
runtime if guards are removed.

Available stack space is now optimized. Some arches may
need to significantly round up the buffer size to account
for page-level granularity or MPU power-of-two requirements.
This space is now accounted for and used by virtue of
the Z_THREAD_STACK_SIZE_ADJUST() call in z_setup_new_thread.

Andrew Boie 1ff066548a ztest: end tests more robustly
If a ztest test case creates child thread(s), and one of the
descendent threads invokes ztest_test_pass(), ztest_test_fail(),
or ztest_thread_skip(), only that descendent thread will be
aborted.

Then ztest will try to run the next scenario on the ztest_thread
which is already in use. This was causing corruption issues on
SMP systems, and possibly other subtle, hard-to-debug
situations.

This patch ensures that ztest_thread is always dead before
re-using it, as run_test() now attempts to join on it instead
of using a semaphore.

The ztest_test_* functions now ensure that the ztest_thread
is always aborted, in addition to the current thread.

This isn't perfect. If the testcase spawned other threads,
they will keep running. The most robust way to fix this is to
iterate over all non-essential threads in the system and abort
them. Unfortunately, Zephyr doesn't have a facility to do
this safely.

It would also be simpler to re-use thread objects if
k_thread_create() could detect whether the thread was already
active and abort it, but this is currently not possible
since k_thread_create() can be used with uninitialzed
thread object memory and no checks are possible. This
may be improved in the future, see #23030.

Andy Ross 32bb2395c2 timeout: Fix up API usage
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.

Stephanos Ioannidis a033683783 arch: arm: aarch32: Rename cortex_r to cortex_a_r
This commit renames the `cortex_r` directory under the AArch32 to
`cortex_a_r`, in preparation for the AArch32 Cortex-A support.

The rationale for this renaming is that the Cortex-A and Cortex-R share
the same base design and the difference between them, other than the
MPU vs. MMU, is minimal.

Since most of the architecture port code and configurations will be
shared between the Cortex-A and Cortex-R architectures, it is
advantageous to have them together in the same directory.

Ulf Magnusson eddd98f811 kconfig: Replace some single-symbol 'if's with 'depends on'
I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.

There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.

The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).

Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.

Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.

Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.

The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.

(Everything above is true for choices, menus, and comments as well.)

Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

Stephanos Ioannidis 2d7460482d headers: Refactor kernel and arch headers.
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 commit supersedes #20047, addresses #19666, and fixes #3056.

Andy Ross efc1ec037b ztest: Add "1cpu" test variants for SMP
The test suite is filled with tests that make assumptions (e.g. about
exactly when other threads will be scheduled) that don't work when
there is another CPU available to handle the load.

Add a feature to the test suite that can "hold" all but one CPU while
the test executes, leveraging the very nice setup/teardown callbacks
to do it.  When there is only one CPU, this becomes a very fast noop
of course.

Note that the hold is done by disabling interrupts and spinning, so it
comes with significant CPU cost and tends to drive up the load on the
CI system (and cause other spurious failures on unrelated tests!), so
this can't be used for long-running test cases.

This commit adds basic userspace support to the logging subsystem.
With this change, the following API could be called from user mode:

- LOG_HEXDUMP_*(),
- LOG_HEXDUMP_INST_*(),
- LOG_PANIC(), LOG_PROCESS(),
- log_printk(), log_generic(), log_buffrered_cnt(),
- log_filter_set(NULL, ...)

With userspace disabled, the logger behavior and performance
is not affected. With userspace enabled, the calls from kernel
space have an additional overhead introduced by _is_user_context().

The logger behavior changes when it is called from the user context.
All strings logged using LOG_*() and LOG_INST_*() API from userspace
are rendered in place for security reasons and then placed in

Marc Herbert 4afcc0f8af sanitycheck: CONFIG_TEST_USERSPACE / userspace tag cleanup
- Delete CONFIG_TEST_USERSPACE=n no-ops because it's the default
since commit 7b1ee5cf13

- Some tests have a "userspace" tag pretending to TEST_USERSPACE but
don't and vice versa: fix missing or spurious "userspace" tags in
testcase.yaml files.

Tests have a _spurious_ "userspace" tag when they PASS this command
cause none should pass:

  ./scripts/sanitycheck --tag=userspace -p qemu_x86 \
      --extra-args=CONFIG_TEST_USERSPACE=n  \
      --extra-args=CONFIG_USERSPACE=n | tee userspace.log

All tests run by this command must either fail to build or fail to run
with some userspace related error. Shortcut to look at all test
failures:

 zephyr_failure_logs() {
     awk '/see.*log/ {print $2}' "$@"
 }

Tests _missing_ "userspace" tag FAIL to either build or to run with some
userspace related error when running this:

  ./scripts/sanitycheck --exclude=userspace -p qemu_x86 \
      --extra-args=CONFIG_TEST_USERSPACE=n  \
      --extra-args=CONFIG_USERSPACE=n | tee excludeuserspace.log

Note the detection methods above are not 100% perfect because some
flexible tests like tests/kernel/queue/src/main.c evade them with #ifdef
CONFIG_USERSPACE smarts. Considering they never break, it is purely the
test author's decision to include or not such flexible tests in the
"userspace" subset.

Andrew Boie fd49cf7d02 kernel: timeout: add syscall for runtime clk freq
If the system sets its clock frequency at runtime, this is
stored in a variable that can't be directly read by user
mode. For this case only, add a system call to fetch its
value and modify the definition of
sys_clock_hw_cycles_per_sec() to use it.

Since this is now a system call, store in a temporary variable
inside z_ms_to_ticks(). The syscall overhead only applies
when called from user mode, other contexts are completely
inlined.

Added stub syscall header for mocking framework, to get rid
of inclusion errors.

Andrew Boie 7b1ee5cf13 tests: CONFIG_TEST_USERSPACE now off by default
Unlike CONFIG_HW_STACK_PROTECTION, which greatly helps
expose stack overflows in test code, activating
userspace without putting threads in user mode is of
very limited value.

Now CONFIG_TEST_USERSPACE is off by default. Any test
which puts threads in user mode will need to set
CONFIG_TEST_USERSPACE.

This should greatly increase sanitycheck build times
as there is non-trivial build time overhead to
enabling this feature. This also allows some tests
which failed the build on RAM-constrained platforms
to compile properly.

tests/drivers/build_all is a special case; it doesn't
put threads in user mode, but we want to ensure all
the syscall handlers compile properly.

   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'

   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
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.

linker and usb files. These are
   drivers/serial/uart_handlers.c

Andrew Boie feab37096b libc: fix CONFIG_STDOUT_CONSOLE semantics
The intent of this Kconfig is to allow libc stdout
functions like printf() to send their output to the
active console driver instead of discarding it.

This somehow evolved into preferring to use
printf() instead of printk() for all test case output
if enabled. Libc printf() implementation for both
minimal libc and newlib use considerably more stack
space than printk(), with nothing gained by using
them.

Remove all instances where we are conditionally
sending test case output based on this config, enable
it by default, and adjust a few tests that disabled
this because they were blowing stack.

printk() and vprintk() now work as expected for
unit_testing targets, they are just wrappers for
host printf().
