This is to align with kunit's terminology.

perf test: Make each test/suite its own struct.

2021-11-13T13:30:04Z

By switching to an array of pointers to tests (later to be suites) the definition of the tests can be moved to the file containing the tests. Committer notes: It's "&vectors_page", not "&vectors_pages", noticed when cross building to 32-bit ARM. Also the DEFINE_SUITE(vectors_page) should be done where its function is implemented, in tools/perf/arch/arm/tests/vectors-page.c, so that we can make it static, as we don't have anymore its declaration in tests.h.

perf tests: Consolidate test__arch_unwind_sample declaration

2021-05-21T19:57:43Z

There's no reason for making the test__arch_unwind_sample declaration per arch. Currently that's done 2 different ways either with a declaration in arch-tests.h or with an arch define. Unify all this with an unconditional declaration in tests.h.

perf tools arm64: Add libdw DWARF post unwind support for ARM64

2018-03-16T16:53:46Z

Based on prior work: https://lkml.org/lkml/2014/5/6/395 and on how other arches add libdw unwind support. Includes support for running the unwind test, e.g., on a system with only elfutils' libdw 0.170, the test now runs, and successfully: $ ./perf test unwind 56: Test dwarf unwind : Ok Originally-by: Jean Pihet Reported-by: Christian Hansen Signed-off-by: Kim Phillips Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20180308211030.4ee4a0d6ff6dc5cda1b567d4@arm.com Signed-off-by: Arnaldo Carvalho de Melo
