From a89248c87b1610a6ecd1d383e6f7890d4b27e5e6 Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Sat, 6 Apr 2013 08:48:26 -0700 Subject: [PATCH] perf: Power7: Make CPI stack events available in sysfs A set of Power7 events are often used for Cycles Per Instruction (CPI) stack analysis. Make these events available in sysfs (/sys/devices/cpu/events/) so they can be identified using their symbolic names: perf stat -e 'cpu/PM_CMPLU_STALL_DCACHE_MISS/' /bin/ls Signed-off-by: Sukadev Bhattiprolu Acked-by: Paul Mackerras Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Cc: linuxppc-dev@ozlabs.org Link: http://lkml.kernel.org/r/20130406164803.GA408@us.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- arch/powerpc/perf/power7-pmu.c | 73 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) diff --git a/arch/powerpc/perf/power7-pmu.c b/arch/powerpc/perf/power7-pmu.c index 3c475d6..13c3f0e 100644 --- a/arch/powerpc/perf/power7-pmu.c +++ b/arch/powerpc/perf/power7-pmu.c @@ -62,6 +62,29 @@ #define PME_PM_BRU_FIN 0x10068 #define PME_PM_BRU_MPRED 0x400f6 +#define PME_PM_CMPLU_STALL_FXU 0x20014 +#define PME_PM_CMPLU_STALL_DIV 0x40014 +#define PME_PM_CMPLU_STALL_SCALAR 0x40012 +#define PME_PM_CMPLU_STALL_SCALAR_LONG 0x20018 +#define PME_PM_CMPLU_STALL_VECTOR 0x2001c +#define PME_PM_CMPLU_STALL_VECTOR_LONG 0x4004a +#define PME_PM_CMPLU_STALL_LSU 0x20012 +#define PME_PM_CMPLU_STALL_REJECT 0x40016 +#define PME_PM_CMPLU_STALL_ERAT_MISS 0x40018 +#define PME_PM_CMPLU_STALL_DCACHE_MISS 0x20016 +#define PME_PM_CMPLU_STALL_STORE 0x2004a +#define PME_PM_CMPLU_STALL_THRD 0x1001c +#define PME_PM_CMPLU_STALL_IFU 0x4004c +#define PME_PM_CMPLU_STALL_BRU 0x4004e +#define PME_PM_GCT_NOSLOT_IC_MISS 0x2001a +#define PME_PM_GCT_NOSLOT_BR_MPRED 0x4001a +#define PME_PM_GCT_NOSLOT_BR_MPRED_IC_MISS 0x4001c +#define PME_PM_GRP_CMPL 0x30004 +#define PME_PM_1PLUS_PPC_CMPL 0x100f2 +#define PME_PM_CMPLU_STALL_DFU 0x2003c +#define PME_PM_RUN_CYC 0x200f4 +#define PME_PM_RUN_INST_CMPL 0x400fa + /* * Layout of constraint bits: * 6666555555555544444444443333333333222222222211111111110000000000 @@ -393,6 +416,31 @@ POWER_EVENT_ATTR(LD_MISS_L1, LD_MISS_L1); POWER_EVENT_ATTR(BRU_FIN, BRU_FIN) POWER_EVENT_ATTR(BRU_MPRED, BRU_MPRED); +POWER_EVENT_ATTR(CMPLU_STALL_FXU, CMPLU_STALL_FXU); +POWER_EVENT_ATTR(CMPLU_STALL_DIV, CMPLU_STALL_DIV); +POWER_EVENT_ATTR(CMPLU_STALL_SCALAR, CMPLU_STALL_SCALAR); +POWER_EVENT_ATTR(CMPLU_STALL_SCALAR_LONG, CMPLU_STALL_SCALAR_LONG); +POWER_EVENT_ATTR(CMPLU_STALL_VECTOR, CMPLU_STALL_VECTOR); +POWER_EVENT_ATTR(CMPLU_STALL_VECTOR_LONG, CMPLU_STALL_VECTOR_LONG); +POWER_EVENT_ATTR(CMPLU_STALL_LSU, CMPLU_STALL_LSU); +POWER_EVENT_ATTR(CMPLU_STALL_REJECT, CMPLU_STALL_REJECT); + +POWER_EVENT_ATTR(CMPLU_STALL_ERAT_MISS, CMPLU_STALL_ERAT_MISS); +POWER_EVENT_ATTR(CMPLU_STALL_DCACHE_MISS, CMPLU_STALL_DCACHE_MISS); +POWER_EVENT_ATTR(CMPLU_STALL_STORE, CMPLU_STALL_STORE); +POWER_EVENT_ATTR(CMPLU_STALL_THRD, CMPLU_STALL_THRD); +POWER_EVENT_ATTR(CMPLU_STALL_IFU, CMPLU_STALL_IFU); +POWER_EVENT_ATTR(CMPLU_STALL_BRU, CMPLU_STALL_BRU); +POWER_EVENT_ATTR(GCT_NOSLOT_IC_MISS, GCT_NOSLOT_IC_MISS); + +POWER_EVENT_ATTR(GCT_NOSLOT_BR_MPRED, GCT_NOSLOT_BR_MPRED); +POWER_EVENT_ATTR(GCT_NOSLOT_BR_MPRED_IC_MISS, GCT_NOSLOT_BR_MPRED_IC_MISS); +POWER_EVENT_ATTR(GRP_CMPL, GRP_CMPL); +POWER_EVENT_ATTR(1PLUS_PPC_CMPL, 1PLUS_PPC_CMPL); +POWER_EVENT_ATTR(CMPLU_STALL_DFU, CMPLU_STALL_DFU); +POWER_EVENT_ATTR(RUN_CYC, RUN_CYC); +POWER_EVENT_ATTR(RUN_INST_CMPL, RUN_INST_CMPL); + static struct attribute *power7_events_attr[] = { GENERIC_EVENT_PTR(CYC), GENERIC_EVENT_PTR(GCT_NOSLOT_CYC), @@ -411,6 +459,31 @@ static struct attribute *power7_events_attr[] = { POWER_EVENT_PTR(LD_MISS_L1), POWER_EVENT_PTR(BRU_FIN), POWER_EVENT_PTR(BRU_MPRED), + + POWER_EVENT_PTR(CMPLU_STALL_FXU), + POWER_EVENT_PTR(CMPLU_STALL_DIV), + POWER_EVENT_PTR(CMPLU_STALL_SCALAR), + POWER_EVENT_PTR(CMPLU_STALL_SCALAR_LONG), + POWER_EVENT_PTR(CMPLU_STALL_VECTOR), + POWER_EVENT_PTR(CMPLU_STALL_VECTOR_LONG), + POWER_EVENT_PTR(CMPLU_STALL_LSU), + POWER_EVENT_PTR(CMPLU_STALL_REJECT), + + POWER_EVENT_PTR(CMPLU_STALL_ERAT_MISS), + POWER_EVENT_PTR(CMPLU_STALL_DCACHE_MISS), + POWER_EVENT_PTR(CMPLU_STALL_STORE), + POWER_EVENT_PTR(CMPLU_STALL_THRD), + POWER_EVENT_PTR(CMPLU_STALL_IFU), + POWER_EVENT_PTR(CMPLU_STALL_BRU), + POWER_EVENT_PTR(GCT_NOSLOT_IC_MISS), + POWER_EVENT_PTR(GCT_NOSLOT_BR_MPRED), + + POWER_EVENT_PTR(GCT_NOSLOT_BR_MPRED_IC_MISS), + POWER_EVENT_PTR(GRP_CMPL), + POWER_EVENT_PTR(1PLUS_PPC_CMPL), + POWER_EVENT_PTR(CMPLU_STALL_DFU), + POWER_EVENT_PTR(RUN_CYC), + POWER_EVENT_PTR(RUN_INST_CMPL), NULL }; -- 2.7.4
