[PATCH V4] perf vendor events riscv: add T-HEAD C9xx JSON file
From: Inochi Amaoto
Date: Sat Aug 26 2023 - 04:44:50 EST
Add json file of T-HEAD C9xx series events.
The event idx (raw value) is summary as following:
event id range | support cpu
0x01 - 0x2a | c906,c910,c920
The event ids are based on the public document of T-HEAD and cover
the c900 series.
These events are the max that c900 series support.
Since T-HEAD let manufacturers decide whether events are usable,
the final support of the perf events is determined by the pmu node
of the soc dtb.

Change from V3:
1. fix some typo in json file
2. correct the event id range in commit
3. rename directory to c900-legacy to identify the old T-HEAD cpus
This patch need the following patches for opensbi to function normaly:

The dtb patch:

A test result on D1 board with mainline opensbi and mainline kernel:
