From: Kan Liang Date: Fri, 1 May 2020 12:54:42 +0000 (-0700) Subject: perf/x86/intel: Add more available bits for OFFCORE_RESPONSE of Intel Tremont X-Git-Tag: v5.4.47~91 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d872f174218de94d99a6d1d1910dbf960bbe48f5;p=platform%2Fkernel%2Flinux-rpi.git perf/x86/intel: Add more available bits for OFFCORE_RESPONSE of Intel Tremont commit 0813c40556fce1eeefb996e020cc5339e0b84137 upstream. The mask in the extra_regs for Intel Tremont need to be extended to allow more defined bits. "Outstanding Requests" (bit 63) is only available on MSR_OFFCORE_RSP0; Fixes: 6daeb8737f8a ("perf/x86/intel: Add Tremont core PMU support") Reported-by: Stephane Eranian Signed-off-by: Kan Liang Signed-off-by: Peter Zijlstra (Intel) Cc: stable@vger.kernel.org Link: https://lkml.kernel.org/r/20200501125442.7030-1-kan.liang@linux.intel.com Signed-off-by: Greg Kroah-Hartman --- diff --git a/arch/x86/events/intel/core.c b/arch/x86/events/intel/core.c index c531e3f32..0461ab257 100644 --- a/arch/x86/events/intel/core.c +++ b/arch/x86/events/intel/core.c @@ -1892,8 +1892,8 @@ static __initconst const u64 tnt_hw_cache_extra_regs static struct extra_reg intel_tnt_extra_regs[] __read_mostly = { /* must define OFFCORE_RSP_X first, see intel_fixup_er() */ - INTEL_UEVENT_EXTRA_REG(0x01b7, MSR_OFFCORE_RSP_0, 0xffffff9fffull, RSP_0), - INTEL_UEVENT_EXTRA_REG(0x02b7, MSR_OFFCORE_RSP_1, 0xffffff9fffull, RSP_1), + INTEL_UEVENT_EXTRA_REG(0x01b7, MSR_OFFCORE_RSP_0, 0x800ff0ffffff9fffull, RSP_0), + INTEL_UEVENT_EXTRA_REG(0x02b7, MSR_OFFCORE_RSP_1, 0xff0ffffff9fffull, RSP_1), EVENT_EXTRA_END };
