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 Signed-off-by: Kan Liang <Kan.liang@xxxxxxxxx> Cc: Alexander Shishkin <alexander.shishkin@xxxxxxxxxxxxxxx> Cc: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> Cc: Jiri Olsa <jolsa@xxxxxxxxxx> Cc: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx> Cc: Peter Zijlstra <peterz@xxxxxxxxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: eranian@xxxxxxxxxx Link: http://lkml.kernel.org/r/20170619142609.11058-1-kan.liang@xxxxxxxxx Signed-off-by: Ingo Molnar <mingo@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- arch/x86/events/intel/core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/arch/x86/events/intel/core.c +++ b/arch/x86/events/intel/core.c @@ -431,11 +431,11 @@ static __initconst const u64 skl_hw_cach [ C(DTLB) ] = { [ C(OP_READ) ] = { [ C(RESULT_ACCESS) ] = 0x81d0, /* MEM_INST_RETIRED.ALL_LOADS */ - [ C(RESULT_MISS) ] = 0x608, /* DTLB_LOAD_MISSES.WALK_COMPLETED */ + [ C(RESULT_MISS) ] = 0xe08, /* DTLB_LOAD_MISSES.WALK_COMPLETED */ }, [ C(OP_WRITE) ] = { [ C(RESULT_ACCESS) ] = 0x82d0, /* MEM_INST_RETIRED.ALL_STORES */ - [ C(RESULT_MISS) ] = 0x649, /* DTLB_STORE_MISSES.WALK_COMPLETED */ + [ C(RESULT_MISS) ] = 0xe49, /* DTLB_STORE_MISSES.WALK_COMPLETED */ }, [ C(OP_PREFETCH) ] = { [ C(RESULT_ACCESS) ] = 0x0, Patches currently in stable-queue which might be from Kan.liang@xxxxxxxxx are queue-4.11/perf-x86-intel-add-1g-dtlb-load-store-miss-support-for-skl.patch
