[PATCH v7 28/28] coresight: Add support for v8.4 SelfHosted tracing

2021-01-10 Thread Suzuki K Poulose
From: Jonathan Zhou v8.4 tracing extensions added support for trace filtering controlled by TRFCR_ELx. This must be programmed to allow tracing at EL1/EL2 and EL0. The timestamp used is the virtual time. Also enable CONTEXIDR_EL2 tracing if we are running the kernel at EL2. Cc: Catalin Marinas
