From 53c218da220c3619b5befec4674ffa35d590092a Mon Sep 17 00:00:00 2001 From: Tuan Phan Date: Wed, 4 Nov 2020 11:30:43 -0800 Subject: driver/perf: Add PMU driver for the ARM DMC-620 memory controller DMC-620 PMU supports total 10 counters which each is independently programmable to different events and can be started and stopped individually. Currently, it only supports ACPI. Other platforms feel free to test and add support for device tree. Usage example: #perf stat -e arm_dmc620_10008c000/clk_cycle_count/ -C 0 Get perf event for clk_cycle_count counter. #perf stat -e arm_dmc620_10008c000/clkdiv2_allocate,mask=0x1f,match=0x2f, incr=2,invert=1/ -C 0 The above example shows how to specify mask, match, incr, invert parameters for clkdiv2_allocate event.
