From f5bfa23f576fdcc8e0b7fbff44cf70bd69ff9bdb Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Fri, 18 Feb 2022 16:46:54 -0800 Subject: RISC-V: Add a perf core library for pmu drivers Implement a perf core library that can support all the essential perf features in future. It can also accommodate any type of PMU implementation in future. Currently, both SBI based perf driver and legacy driver implemented uses the library. Most of the common perf functionalities are kept in this core library wile PMU specific driver can implement PMU specific features. For example, the SBI specific functionality will be implemented in the SBI specific driver.
