Commit Message

Inochi Amaoto Nov. 22, 2023, 12:41 p.m. UTC 
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:
https://lists.infradead.org/pipermail/opensbi/2023-August/005500.html

The dtb patch:
https://lists.infradead.org/pipermail/linux-riscv/2023-August/039040.html

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