perf: tests: Adapt mmap-basic.c for riscv

2023-08-16T14:28:23+00:00

riscv now supports mmaping hardware counters to userspace so adapt the test to run on this architecture. Signed-off-by: Alexandre Ghiti Reviewed-by: Andrew Jones Reviewed-by: Atish Patra Reviewed-by: Ian Rogers

perf tests: Add missing event.h include

2022-10-31T14:07:08+00:00

It uses things like perf_event__name() but were not including event.h, where its prototype lives, fix it. Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Move 'struct perf_sample' to a separate header file to disentangle headers

2022-10-31T14:06:41+00:00

Some places were including event.h just to get 'struct perf_sample', move it to a separate place so that we speed up a bit the build. Signed-off-by: Arnaldo Carvalho de Melo

perf tests: Avoid pthread.h inclusion

2022-10-04T11:55:19+00:00

pthread.h is being included for the side-effect of getting sched.h and macros like CPU_CLR. Switch to directly using sched.h, or if that is already present, just remove the pthread.h inclusion entirely.

perf test: Add user space counter reading tests

2022-08-01T12:20:18+00:00

These tests are based on test_stat_user_read in tools/lib/perf/tests/test-evsel.c. The tests are modified to skip if perf_event_open fails or rdpmc isn't supported.

perf test: Basic mmap use skip

2022-05-23T13:03:39+00:00

If opening the event fails for basic mmap with EACCES it is more likely permission related that a true error. Mark the test as skip in this case and add a skip reason.

perf cpumap: Give CPUs their own type

2022-01-12T17:28:23+00:00

A common problem is confusing CPU map indices with the CPU, by wrapping the CPU with a struct then this is avoided. This approach is similar to atomic_t. Committer notes: To make it build with BUILD_BPF_SKEL=1 these files needed the conversions to 'struct perf_cpu' usage: tools/perf/util/bpf_counter.c tools/perf/util/bpf_counter_cgroup.c tools/perf/util/bpf_ftrace.c Also perf_env__get_cpu() was removed back in "perf cpumap: Switch cpu_map__build_map to cpu function".
