perf/uapi: Clean up a bit

2025-05-22T09:03:41+00:00

When applying a recent commit to the header I noticed that we have accumulated quite a bit of historic noise in this header, so do a bit of spring cleaning: - Define bitfields in a vertically aligned fashion, like perf_event_mmap_page::capabilities already does. This makes it easier to see the distribution and sizing of bits within a word, at a glance. The following is much more readable: __u64 cap_bit0 : 1, cap_bit0_is_deprecated : 1, cap_user_rdpmc : 1, cap_user_time : 1, cap_user_time_zero : 1, cap_user_time_short : 1, cap_____res : 58; Than: __u64 cap_bit0:1, cap_bit0_is_deprecated:1, cap_user_rdpmc:1, cap_user_time:1, cap_user_time_zero:1, cap_user_time_short:1, cap_____res:58; So convert all bitfield definitions from the latter style to the former style. - Fix typos and grammar - Fix capitalization - Remove whitespace noise - Harmonize the definitions of various generations and groups of PERF_MEM_ ABI values. - Vertically align all definitions and assignments to the same column (48), as the first definition (enum perf_type_id), throughout the entire header. - And in general make the code and comments to be more in sync with each other and to be more readable overall. No change in functionality. Copy the changes over to tools/include/uapi/linux/perf_event.h.

perf/uapi: Fix PERF_RECORD_SAMPLE comments in

2025-05-22T08:01:34+00:00

AAUX data for PERF_SAMPLE_AUX appears last. PERF_SAMPLE_CGROUP is missing from the comment. This makes the comment match that in the perf_event_open man page.
