From: Chen Pei <cp0613@linux.alibaba.com>
Add PMU event descriptions for the C-SKY C930 core so perf can list and
select its hardware events by name instead of requiring raw event codes.
The events cover core counters, branch prediction, instruction fetch,
integer execution, load/store operations, vector and floating-point
execution, caches and TLBs.
Add a mapfile.csv entry matching mvendorid 0x5b7 and marchid
0x8000000009201600, allowing any mimpid, to select the C930 event table.
For example:
perf stat -e cache.l1d.rd.miss,tlb.l1d.miss ./workload

XuanTie is the RISC-V processor brand of C-SKY Microsystems Co., Ltd.
[2]. JEDEC JEP106AB lists C-SKY Microsystems Co., Ltd. as the manufacturer
associated with ID 0x5b7 [3]. Accordingly, use C-SKY in the patch title
and csky/ as the vendor directory.
This revision is limited to the PMU event descriptions from v2 3/4.
perf selects the event table by matching mvendorid, marchid and mimpid,
so the DT binding additions are not required for this patch. The
derived metrics patch is also omitted from this revision.
Changes in v3:
- Repost only the PMU event patch. Omit the DT binding patches
(v2 1/4 and 2/4) and the derived metrics patch (v2 4/4).
- Rename the vendor directory from xuantie/ to csky/ and update the
mapfile.csv entry accordingly.
- Change the patch title to "Add C-SKY C930 PMU events".
- Drop the topdown.* events, uop.spec, uop.ret, ieu.de.inst_cnt,
ieu.rn.inst_cnt and vfpu_ex1_rep.
Changes in v2:
v2: https://lore.kernel.org/linux-riscv/20251121063439.2545-1-cp0613@linux.alibaba.com/
- Vendor name update.
Previous versions:
v1: https://lore.kernel.org/linux-riscv/20250910121121.7203-1-cp0613@linux.alibaba.com/
