tools headers UAPI: Sync perf_event.h with the kernel sources

2021-05-10T12:01:01+00:00

To pick up the changes in: 2b26f0aa004995f4 ("perf: Support only inheriting events if cloned with CLONE_THREAD") 2e498d0a74e5b88a ("perf: Add support for event removal on exec") 547b60988e631f74 ("perf: aux: Add flags for the buffer format") 55bcf6ef314ae8ba ("perf: Extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE") 7dde51767ca5339e ("perf: aux: Add CoreSight PMU buffer formats") 97ba62b278674293 ("perf: Add support for SIGTRAP on perf events") d0d1dd628527c77d ("perf core: Add PERF_COUNT_SW_CGROUP_SWITCHES event") Also change the expected sizeof(struct perf_event_attr) from 120 to 128 due to fields being added for the SIGTRAP changes.

perf tools: Add kernel AUX area sampling definitions

2019-11-21T13:54:20+00:00

Add kernel AUX area sampling definitions, which brings perf_event.h into line with the kernel version. New sample type PERF_SAMPLE_AUX requests a sample of the AUX area buffer. New perf_event_attr member 'aux_sample_size' specifies the desired size of the sample. Also add support for parsing samples containing AUX area data i.e. PERF_SAMPLE_AUX. Committer notes: I squashed the first two patches in this series to avoid breaking automatic bisection, i.e. after applying only the original first patch in this series we would have: # perf test -v parsing 26: Sample parsing : --- start --- test child forked, pid 17018 sample format has changed, some new PERF_SAMPLE_ bit was introduced - test needs updating test child finished with -1 ---- end ---- Sample parsing: FAILED! # With the two paches combined: # perf test parsing 26: Sample parsing : Ok # Signed-off-by: Adrian Hunter Tested-by: Arnaldo Carvalho de Melo Cc: Jiri Olsa Link: http://lore.kernel.org/lkml/20191115124225.5247-3-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf tests attr: Fix stat sample_type setup

2017-07-19T02:14:21+00:00

>From following commit: commit 4979d0c7d0c7 ("perf stat record: Add record command") we started to assign PERF_SAMPLE_IDENTIFIER to sample_type. Fixing the attr stat tests accordingly.

perf tests attr: Add 1s for exclude_kernel and task base bits

2017-07-19T02:14:17+00:00

There's an event open fallback which set exclude_kernel=1 in case use does not have enough privileges. Adding both 0|1 for this attribute, because we don't know what value it is.

perf tests: Fix exclude_guest|exclude_host checking for attr tests

2013-05-29T12:15:19+00:00

We have a one of the event open fallback case in __perf_evsel__open where we zero exclude_guest|exclude_host fields. This means there's no way for attr tests to find out what's the right value for those fields, so we need to check for both 0 and 1. Luckily we still have other event parsing tests for those fields.

perf tests: Make attr script test event cpu

2013-03-15T16:06:00+00:00

Make attr script to check for 'cpu' when testing event properties. This will allow us to check the '-C X' option for both record and stat commands.

perf tests: Removing 'optional' field

2012-11-05T17:03:59+00:00

Since we allow multiple values in event field assignment, there's no need for 'optional' field.. old version removal leftover. Adding some comments into attr.py script regarding the test event load.
