powerpc: Replace __ASSEMBLY__ with __ASSEMBLER__ in non-uapi headers2025-09-01T07:53:29+00:00Thomas Huththuth@redhat.com2025-08-01T08:20:07+00:00urn:sha1:74db6cc331b0da5c48c62b7af68d747ec9af1984
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembler code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This is bad since macros starting with two underscores are names
that are reserved by the C language. It can also be very confusing
for the developers when switching between userspace and kernelspace
coding, or when dealing with uapi headers that rather should use
__ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__
macro that is provided by the compilers.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), apart from tweaking two comments manually in
arch/powerpc/include/asm/bug.h and arch/powerpc/include/asm/kasan.h
(which did not have proper underscores at the end) and fixing a
checkpatch error about spaces in arch/powerpc/include/asm/spu_csa.h.

has been queued to arm64/for-next/pkey_unrestricted which is causing a build break
in the selftest/powerpc builds.
Commit 6d61527d931ba ("mm/pkey: Add PKEY_UNRESTRICTED macro") added a macro
PKEY_UNRESTRICTED to handle implicit literal value of 0x0 (which is "unrestricted").
Add the same to selftest/powerpc/pkeys.h to fix the reported build break.

auxv_generic_compat_pmu() utility function is to detect whether the
system is having generic compat PMU. The check is based on base platform
value from /proc/self/auxv. Update the comment with details on how auxv
is used to detect the platform.

The testcase uses check_extended_regs_support and
perf_get_platform_reg_mask function to check if the
platform has extended reg support. This will help to
check if sampling pmu selftest is enabled or not for
a given platform.

tools/testing/selftests/powerpc: Add check for power11 pvr for pmu selfests2025-02-11T06:03:51+00:00Athira Rajeevatrajeev@linux.vnet.ibm.com2025-01-13T07:58:55+00:00urn:sha1:520ee327c59d37c5520b177404f57c974cc098cc
Some of the tests depends on pvr value to choose
the event. Example:
- event_alternatives_tests_p10: alternative event depends
on registered PMU driver which is based on pvr
- generic_events_valid_test varies based on platform
- bhrb_filter_map_test: again its dependent on pmu to
decide which bhrb filter to use
- reserved_bits_mmcra_sample_elig_mode: randome sampling
mode reserved bits is also varies based on platform

Add check for power11 pvr in the selftest utility
functions. Selftests uses pvr value to check for platform
support inorder to run the tests. pvr is also used to
send the extended mask value to capture sampling registers.
Update some of the utility functions to use hwcap2 inorder
to return platform specific bits from sampling registers.
