perf/x86/intel: Add Cannon Lake support for RAPL profiling This patch enables RAPL counters (energy consumption counters) support for Cannon Lake processors. ( ESU and power domains refer to Intel Software Developers' Manual, Vol. 4, Order No. 335592. ) Usage example: $ perf list $ perf stat -a -e power/energy-cores/,power/energy-pkg/ sleep 10 Tested-by: Puthikorn Voravootivat <[email protected]> Signed-off-by: Harry Pan <[email protected]> Reviewed-by: Benson Leung <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: Arnaldo Carvalho de Melo <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Linus Torvalds <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Cc: Thomas Gleixner <[email protected]> Cc: Vince Weaver <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ingo Molnar <[email protected]> --- arch/x86/events/intel/rapl.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/x86/events/intel/rapl.c b/arch/x86/events/intel/rapl.c index a2efb490f743..32f3e9423e99 100644 --- a/arch/x86/events/intel/rapl.c +++ b/arch/x86/events/intel/rapl.c @@ -774,6 +774,8 @@ static const struct x86_cpu_id rapl_cpu_match[] __initconst = { X86_RAPL_MODEL_MATCH(INTEL_FAM6_KABYLAKE_MOBILE, skl_rapl_init), X86_RAPL_MODEL_MATCH(INTEL_FAM6_KABYLAKE_DESKTOP, skl_rapl_init), + X86_RAPL_MODEL_MATCH(INTEL_FAM6_CANNONLAKE_MOBILE, skl_rapl_init), + X86_RAPL_MODEL_MATCH(INTEL_FAM6_ATOM_GOLDMONT, hsw_rapl_init), X86_RAPL_MODEL_MATCH(INTEL_FAM6_ATOM_DENVERTON, hsw_rapl_init),
