config CONFIG_HISI_PMU for kunpeng920

Hi,

I believe you are suggesting merging patch 97807325a02b ("drivers/perf: hisi: Permit modular builds of HiSilicon uncore drivers") and CONFIG_HISI_PMU=m.

Is there any testcase for PMU driver that we can verify driver is good?

hi
you can refer to this following guide from linus kernel doc：
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/admin-guide/perf/hisi-pmu.rst?h=v5.16-rc8

In both focal-ga and focal-hwe, CONFIG_HISI_PMU is set to =y

Patch 97807325a02b ("drivers/perf: hisi: Permit modular builds of HiSilicon uncore drivers") hits mainline kernel since v5.8 and can be clean cherry-pick to focal-ga.

Is there any reason you need CONFIG_HISI_PMU=m not =y?

Marking as "incomplete" while waiting for the rationale for the change (note that a rationale is essential for an SRU).

we can use this new pmu ko instead of old pmu ko if this system ko exist some bug.

The advantage of build-as-module is 1) Downsize kernel image, 2) Can be removed, 3) Can replace updated driver if needed

The advantage of build-in is 1) Can find rootfs, 2) For early debug

IMO, I will run PMU testcase. If nothing needed for build-in, I will send the patch to build it as module.

Patch 97807325a02b ("drivers/perf: hisi: Permit modular builds of HiSilicon uncore drivers") has been merged into Ubuntu 5.13 and 5.15 kernel but CONFIG_HISI_PMU is =y. Let me try test build with =m and test the driver.

This bug is awaiting verification that the linux/5.13.0-42.47 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-impish' to 'verification-done-impish'. If the problem still exists, change the tag 'verification-needed-impish' to 'verification-failed-impish'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
