Subject: [PATCH 0/2] perf: add T-HEAD C9xx series cpu support
Date: Tue, 16 May 2023 10:37:12 +0800 [thread overview]
Message-ID: <IA1PR20MB49539201E93DE46A9A2A8E74BB799@IA1PR20MB4953.namprd20.prod.outlook.com> (raw)
The T-HEAD C9xx series cpu is a series of riscv CPU IP. As this IP was
proposed before the current riscv event standard. It has a non-standard
events encoding for perf events and unimplemented MARCH and MIMP CSR.
This patch add these events to support C9xx cpus.
AFAIK, at least the following chips used C9xx cpu.
* Allwinner D1 (C906)
* T-HEAD th1520 (C910)
* Sophgo mango (C920)
