Subject: perf/x86/intel: Add 1G DTLB load/store miss support for SKL
From: Kan Liang <[email protected]>
commit fb3a5055cd7098f8d1dd0cd38d7172211113255f upstream.
Current DTLB load/store miss events (0x608/0x649) only counts 4K,2M and 4M page size.
Need to extend the events to support any page size (4K/2M/4M/1G).
The complete DTLB load/store miss events are:
DTLB_LOAD_MISSES.WALK_COMPLETED 0xe08
DTLB_STORE_MISSES.WALK_COMPLETED 0xe49
