Subject: [PATCH V4 0/7] Clean up perf mem

From: Kan Liang <[email protected]>

Changes since V3:
- Fix the powerPC building error (Kajol Jain)
- The s390 does not support perf mem. Remove the code. (Thomas)
- Add reviewed-by and tested-by from Kajol Jain for patch 1 and 2
- Add tested-by from Leo

Changes since V2:
- Fix the Arm64 building error (Leo)
- Add two new patches to clean up perf_mem_events__record_args()
and perf_pmus__num_mem_pmus() (Leo)

Changes since V1:
- Fix strcmp of PMU name checking (Ravi)
- Fix "/," typo (Ian)
- Rename several functions with perf_pmu__mem_events prefix. (Ian)
- Fold the header removal patch into the patch where the cleanups made.
(Arnaldo)
- Add reviewed-by and tested-by from Ian and Ravi

As discussed in the below thread, the patch set is to clean up perf mem.
https://lore.kernel.org/lkml/[email protected]/

Introduce generic functions perf_mem_events__ptr(),
perf_mem_events__name() ,and is_mem_loads_aux_event() to replace the
ARCH specific ones.
Simplify the perf_mem_event__supported().

Only keeps the ARCH-specific perf_mem_events array in the corresponding
mem-events.c for each ARCH.

There is no functional change.

The patch set touches almost all the ARCHs, Intel, AMD, ARM, Power and
etc. But I can only test it on two Intel platforms.
Please give it try, if you have machines with other ARCHs.

Here are the test results:
Intel hybrid machine:

$perf mem record -e list
ldlat-loads : available
ldlat-stores : available

$perf mem record -e ldlat-loads -v --ldlat 50
calling: record -e cpu_atom/mem-loads,ldlat=50/P -e cpu_core/mem-loads,ldlat=50/P

$perf mem record -v
calling: record -e cpu_atom/mem-loads,ldlat=30/P -e cpu_atom/mem-stores/P -e cpu_core/mem-loads,ldlat=30/P -e cpu_core/mem-stores/P

$perf mem record -t store -v
calling: record -e cpu_atom/mem-stores/P -e cpu_core/mem-stores/P


Intel SPR:
$perf mem record -e list
ldlat-loads : available
ldlat-stores : available

$perf mem record -e ldlat-loads -v --ldlat 50
calling: record -e {cpu/mem-loads-aux/,cpu/mem-loads,ldlat=50/}:P

$perf mem record -v
calling: record -e {cpu/mem-loads-aux/,cpu/mem-loads,ldlat=30/}:P -e cpu/mem-stores/P

$perf mem record -t store -v
calling: record -e cpu/mem-stores/P

I think this is ready to land in perf-tools-next, multiple Tested-by
or Reviewed-by.

Sure, queued for a local testing.

Applied to perf-tools-next, thanks!
