[PATCH v5 0/9] Add per-core RAPL energy counter support for AMD CPUs
Posted by Dhananjay Ugwekar 2 months, 2 weeks ago
Currently the energy-cores event in the power PMU aggregates energy
consumption data at a package level. On the other hand the core energy
RAPL counter in AMD CPUs has a core scope (which means the energy 
consumption is recorded separately for each core). Earlier efforts to add
the core event in the power PMU had failed [1], due to the difference in 
the scope of these two events. Hence, there is a need for a new core scope
PMU.

This patchset adds a new "power_per_core" PMU alongside the existing
"power" PMU, which will be responsible for collecting the new
"energy-per-core" event.

Tested the package level and core level PMU counters with workloads
pinned to different CPUs.

Results with workload pinned to CPU 1 in Core 1 on an AMD Zen4 Genoa 
machine:

$ perf stat -a --per-core -e power_per_core/energy-per-core/ -- sleep 1

 Performance counter stats for 'system wide':

S0-D0-C0         1          0.02 Joules power_per_core/energy-per-core/
S0-D0-C1         1          5.72 Joules power_per_core/energy-per-core/
S0-D0-C2         1          0.02 Joules power_per_core/energy-per-core/

v4 Link: https://lore.kernel.org/all/20240711102436.4432-1-Dhananjay.Ugwekar@amd.com/

v5 changes:
* Rebase on top of Kan Liang's "PMU scope" patchset [2]
* rapl_cntr_mask moved to rapl_pmus struct in patch 8
* Patch 1 from v4 is merged separately, so removed from this series
* Add an extra argument "scope" in patch 5 to the init functions
* Add an new patch 2, which removes the cpu_to_rapl_pmu() function

Base: tip/perf/core(currently has just 1-5 patches from [2]) + patch 6 from [2] + 
      diff [3] + patch 7 from [2] + revert [4] + apply [5]

The patch LGTM. But they don't apply to latest upstream because
https://lore.kernel.org/all/20240910085504.204814-1-Dhananjay.Ugwekar@amd.com/
and the upstream version diverges.

will you rebase your patches so that I can give them a try on my Intel
testbox?

thanks,
rui

Thanks for taking a look. 
Yes, I will be rebasing on top of upstream and posting v6, mostly by monday.

Energy reported by core 9 is considerably higher than other cores, which is as expected.

However, can you please post the core_id for CPU 9 just to be sure, also I see that other 
cores are also showing considerable energy consumption(e.g. core 11), are there some other 
tasks running in the background?

Thanks for testing!
