2025-05-21Bluetooth: btnxpuart: Implement host-wakeup featureNeeraj Sanjay Kale
This implements host wakeup feature by reading the device tree property wakeup-source and 'wakeup' interrupt, and nxp,wakeout-pin, and configuring it as a FALLING EDGE triggered interrupt. When host is suspended, a trigger from the WAKE_OUT pin of the controller wakes it up. To enable this feature, both device tree properties are needed to be defined.

2025-05-21KVM: arm64: np-guest CMOs with PMD_SIZE fixmapVincent Donnefort
With the introduction of stage-2 huge mappings in the pKVM hypervisor, guest pages CMO is needed for PMD_SIZE size. Fixmap only supports PAGE_SIZE and iterating over the huge-page is time consuming (mostly due to TLBI on hyp_fixmap_unmap) which is a problem for EL2 latency. Introduce a shared PMD_SIZE fixmap (hyp_fixblock_map/hyp_fixblock_unmap) to improve guest page CMOs when stage-2 huge mappings are installed. On a Pixel6, the iterative solution resulted in a latency of ~700us, while the PMD_SIZE fixmap reduces it to ~100us. Because of the horrendous private range allocation that would be necessary, this is disabled for 64KiB pages systems.

2025-05-21selftests: harness: Stop using setjmp()/longjmp()Thomas Weißschuh
Usage of longjmp() was added to ensure that teardown is always run in commit 63e6b2a42342 ("selftests/harness: Run TEARDOWN for ASSERT failures") However instead of calling longjmp() to the teardown handler it is easier to just call the teardown handler directly from __bail(). Any potential duplicate teardown invocations are harmless as the actual handler will only ever be executed once since commit fff37bd32c76 ("selftests/harness: Fix fixture teardown"). Additionally this removes a incompatibility with nolibc, which does not support setjmp()/longjmp().

2025-05-21selftests: harness: Ignore unused variant argument warningThomas Weißschuh
For tests without fixtures the variant argument is unused. This is intentional, prevent to compiler from complaining. Example warning: harness-selftest.c: In function 'wrapper_standalone_pass': ../kselftest_harness.h:181:52: error: unused parameter 'variant' [-Werror=unused-parameter] 181 | struct __fixture_variant_metadata *variant) \ | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~ ../kselftest_harness.h:156:25: note: in expansion of macro '__TEST_IMPL' 156 | #define TEST(test_name) __TEST_IMPL(test_name, -1) | ^~~~~~~~~~~ harness-selftest.c:15:1: note: in expansion of macro 'TEST' 15 | TEST(standalone_pass) { | ^~~~ Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Reviewed-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Acked-by: Shuah Khan <skhan@linuxfoundation.org> Link: https://lore.kernel.org/r/20250505-nolibc-kselftest-harness-v4-3-ee4dd5257135@linutronix.de Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>

2025-05-21tools/nolibc: implement wait() in terms of waitpid()Thomas Weißschuh
Newer architectures like riscv 32-bit are missing sys_wait4(). Make use of the fact that wait(&status) is defined to be equivalent to waitpid(-1, status, 0) to implement it on all architectures.

2025-05-21tools/nolibc: fall back to sys_clock_gettime() in gettimeofday()Thomas Weißschuh
Newer architectures (like riscv32) do not implement sys_gettimeofday(). In those cases fall back to sys_clock_gettime(). While that does not support the timezone argument of sys_gettimeofday(), specifying this argument invokes undefined behaviour, so it's safe to ignore.

This is used in various selftests and will be handy when integrating those with nolibc. Not all configurations support namespaces, so skip the tests where necessary. Also if the tests are running without privileges. Enable the namespace configuration for those architectures where it is not enabled by default.
