Message-Id: <20210811024827.9483-1-yao.jin@linux.intel.com> Date: Wed, 11 Aug 2021 10:48:25 +0800 From: Jin Yao <yao.jin@...ux.intel.com> To: acme@...nel.org, jolsa@...nel.org, peterz@...radead.org, mingo@...hat.com, alexander.shishkin@...ux.intel.com Cc: Linux-kernel@...r.kernel.org, linux-perf-users@...r.kernel.org, ak@...ux.intel.com, kan.liang@...el.com, yao.jin@...el.com, rickyman7@...il.com, Jin Yao <yao.jin@...ux.intel.com> Subject: [PATCH v4 0/2] perf tools: Add PMU alias support A perf uncore PMU may have two PMU names, a real name and an alias name. With this patch set, the perf tool can monitor the PMU with either the real name or the alias. Use the real name, $ perf stat -e uncore_cha_2/event=1/ -x, 4044879584,,uncore_cha_2/event=1/,2528059205,100.00,, Use the alias, $ perf stat -e uncore_type_0_2/event=1/ -x, 3659675336,,uncore_type_0_2/event=1/,2287306455,100.00,, v4: --- 1. Fix memory leaks in pmu_lookup. 2. Rebase to perf/core. v3: --- 1. Use fgets() to replace fscanf(). 2. Resource cleanup. v2: --- Add test case to verify the real name and alias name having same effect.
