[RFC PATCH 0/6] Support raw event and DT for perf on RISC-V

2020-06-28 Thread Zong Li
This patch set adds raw event support on RISC-V. In addition, we introduce the DT mechanism to make our perf more generic and common. Currently, we set the hardware events by writing the mhpmeventN CSRs, it would raise an illegal instruction exception and trap into m-mode to emulate event selector
