perf mem: Add -e record option
Adding -e option for perf mem record command, to be able to specify
memory event directly.
Get list of available events:
$ perf mem record -e list
ldlat-loads
ldlat-stores
Monitor ldlat-loads:
$ perf mem record -e ldlat-loads true
Committer notes:
Further testing:
# perf mem record -e ldlat-loads true
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (10 samples) ]
# perf evlist
cpu/mem-loads,ldlat=30/P
