Hello!
Qiao Zhao (CC'd) has found out that there are no hwcache events available
on an Arrowlake system he was testing perf on. We have found out that it
does not work even on 6.12.0-rc6+. Are there still drivers that haven't
been merged yet?
Happens that nothing matches in this loop:
int print_hwcache_events(const struct print_callbacks *print_cb, void *print_state)
[...]
305 for (int type = 0; type < PERF_COUNT_HW_CACHE_MAX; type++) {
306 for (int op = 0; op < PERF_COUNT_HW_CACHE_OP_MAX; op++) {
307 /* skip invalid cache type */
308 if (!evsel__is_cache_op_valid(type, op))
309 continue;
310
311 for (int res = 0; res < PERF_COUNT_HW_CACHE_RESULT_MAX; res++) {
312 char name[64];
313 char alias_name[128];
314 __u64 config;
315 int ret;
316
317 __evsel__hw_cache_type_op_res_name(type, op, res,
318 name, sizeof(name));
319
320 ret = parse_events__decode_legacy_cache(name, pmu->type,
321 &config);
322 if (ret || !is_event_supported(PERF_TYPE_HW_CACHE, config))
323 continue;
Thanks,
Michael

There are several variants for Arrowlake.
#define INTEL_ARROWLAKE_H IFM(6, 0xC5)
#define INTEL_ARROWLAKE IFM(6, 0xC6)
#define INTEL_ARROWLAKE_U IFM(6, 0xB5)
The INTEL_ARROWLAKE should be supported in 6.10 and later.
The INTEL_ARROWLAKE_H was just merged and should be available in the
upcoming 6.13-rc.
https://lore.kernel.org/lkml/20240808140210.1666783-1-dapeng1.mi@linux.intel.com/
The patch to support INTEL_ARROWLAKE_U hasn't been posted yet.
Which system were you testing?

The HW cache events are usually model specific events. You cannot see it
unless there is specific support.
You may also get more clues via dmesg | grep PMU.
If you see "generic architected perfmon", it means the specific support
isn't ready in the kernel.

Thanks for the confirmation.
I will find a machine and post a patch to fix it ASAP.

Isn't it ArrowLake-H ?

Good catch. :)
For ARL-H, it should be ready with the upcoming 6.13-rc.

Good to know that. Thank you!
Maybe the machine name is displayed incorrectly in our system. I will
discuss this with our IT.
