From 7517f08b9a5eef0fa683b976c97d6178d00e6a3d Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Wed, 7 Sep 2022 14:49:21 +0530 Subject: [PATCH] perf/core: Expand PERF_EVENT_FLAG_ARCH Two hardware event flags on x86 platform has overshot PERF_EVENT_FLAG_ARCH (0x0000ffff). These flags are PERF_X86_EVENT_PEBS_LAT_HYBRID (0x20000) and PERF_X86_EVENT_AMD_BRS (0x10000). Lets expand PERF_EVENT_FLAG_ARCH mask to accommodate those flags, and also create room for two more in the future.
