Adding Intel DATALA memory events into
perf mem record command:
$ perf mem record -e list
[ok] ldlat-loads
[ok] ldlat-stores
stlb-miss-loads
stlb-miss-stores
lock-loads
split-loads
split-stores
all-loads
all-stores
l1-hit
l2-hit
l3-hit
l1-miss
l2-miss
l3-miss
lfb
snp-miss
snp-hit
snp-hitm
snp-none
local-dram
All events from above lists are compiled in, but only
those with [ok] are supported by kernel/HW. You need
previous DATALA patch to support all of them.
