perf jevents: Add support for Hisi hip08 DDRC PMU aliasing
Add support for Hisi hip08 DDRC PMU aliasing. We can now do something like this: $perf list [snip] uncore ddrc: uncore_hisi_ddrc.act_cmd [DDRC active commands. Unit: hisi_sccl,ddrc] uncore_hisi_ddrc.flux_rcmd [DDRC read commands. Unit: hisi_sccl,ddrc] uncore_hisi_ddrc.flux_wcmd [DDRC write commands. Unit: hisi_sccl,ddrc] uncore_hisi_ddrc.flux_wr [DDRC precharge commands. Unit: hisi_sccl,ddrc] uncore_hisi_ddrc.rnk_chg [DDRC rank commands. Unit: hisi_sccl,ddrc] uncore_hisi_ddrc.rw_chg [DDRC read and write changes. Unit: hisi_sccl,ddrc] Performance counter stats for 'system wide': 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl1_ddrc0] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl3_ddrc1] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl5_ddrc2] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl7_ddrc3] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl5_ddrc0] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl7_ddrc1] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl1_ddrc3] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl1_ddrc1] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl3_ddrc2] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl5_ddrc3] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl3_ddrc0] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl5_ddrc1] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl7_ddrc2] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl7_ddrc0] 20,421 uncore_hisi_ddrc.flux_rcmd [hisi_sccl1_ddrc2] 0 uncore_hisi_ddrc.flux_rcmd [hisi_sccl3_ddrc3] 1.001559011 seconds time elapsed The kernel driver is in drivers/perf/hisilicon/hisi_uncore_ddrc_pmu.c Signed-off-by: John Garry <john.garry@huawei.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ben Hutchings <ben@decadent.org.uk> Cc: Hendrik Brueckner <brueckner@linux.ibm.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Shaokun Zhang <zhangshaokun@hisilicon.com> Cc: Thomas Richter <tmricht@linux.ibm.com> Cc: Will Deacon <will.deacon@arm.com> Cc: linux-arm-kernel@lists.infradead.org Cc: linuxarm@huawei.com Link: http://lkml.kernel.org/r/1561732552-143038-3-git-send-email-john.garry@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
