| |
The documented format of PERF_RECORD_SAMPLE does not match the actual format emitted by perf_output_sample:
* The cgroup field is missing entirely. * The data_page_size and code_page_size fields are output before the aux data, but are documented before.
Fixes: 6546b19f95ac ("perf/core: Add PERF_SAMPLE_CGROUP feature") Fixes: 8d97e71811aa ("perf/core: Add PERF_SAMPLE_DATA_PAGE_SIZE") Fixes: 995f088efebe ("perf/core: Add support for PERF_SAMPLE_CODE_PAGE_SIZE") Signed-off-by: Michael Pratt <mpratt@google.com> --- include/uapi/linux/perf_event.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
