perf thread_map: Remove uid options

2025-06-09T18:18:18Z

Now the target doesn't have a uid, it is handled through BPF filters, remove the uid options to thread_map creation. Tidy up the functions used in tests to avoid passing unused arguments.

perf thread_map: Reduce exposure of libperf internal API

2022-11-16T15:17:15Z

Remove unnecessary include of internal threadmap.h and refcount.h in thread_map.h. Switch to using public APIs when possible or including the internal header file in the C file. Fix a transitive dependency in openat-syscall.c broken by the clean up.

perf test: Use skip in openat syscall

2022-05-23T13:01:57Z

Failures to open the tracepoint cause this test to fail, however, typically such failures are permission related. Lower the failure to just skipping the test in those cases and add a skip reason. Committer testing: Before: $ perf test "openat syscall" 2: Detect openat syscall event : FAILED! 3: Detect openat syscall event on all cpus : FAILED! $ After: $ perf test "openat syscall" 2: Detect openat syscall event : Skip (permissions) 3: Detect openat syscall event on all cpus : Skip (permissions) $ Signed-off-by: Ian Rogers Tested-by: Arnaldo Carvalho de Melo Cc: Alexander Shishkin Cc: Carsten Haitzler Cc: Ingo Molnar Cc: Jiri Olsa Cc: John Garry Cc: Marco Elver Cc: Mark Rutland Cc: Michael Petlan Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Riccardo Mancini Cc: Sohaib Mohamed Cc: Stephane Eranian Link: https://lore.kernel.org/r/20220518042027.836799-4-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo

perf test: Rename struct test to test_suite

perf test: Move each test suite struct to its test

2021-11-13T13:30:58Z

Rather than export test functions, export the test struct. Rename with a suite__ prefix to avoid name collisions. Committer notes: Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when cross building to arm (32-bit).

perf debug: Remove needless include directives from debug.h

2019-08-31T22:10:19Z

All we need there is a forward declaration for 'union perf_event', so remove it from there and add missing header directives in places using things from this indirect include.

perf tests: Add missing counts.h

2019-08-22T20:16:57Z

Those are getting counts.h via evsel.h, that don't strictly need counts.h, just forward declarations for some structs, so add it here before we remove it from there.
