Bug description:
[Impact]
We have Hisilicon PMU modules built-in and they can not be unloaded. There is
no way to replace with a updated module unless we build it as module.
[Test Plan]
`lsmod | grep hisi_uncore` shall see 4 modules loaded and they can be
unloaded.
[Regression Risk]
CONFIG_HISI_PMU shall be only affected Hisilicon platforms that HISI0213 is
found in ACPI tables. We shall have perf test run on these platforms and others
have lowest risk.
=================================
[Bug Description]
hisi pmu support x.ko module to use it for kunpeng920
[Steps to Reproduce]
1) cd /lib/modules/$(uname -r)/kernel/drivers/perf/hisilicon
2) check *.ko
3)
[Actual Results]
@ubuntu:~$ cat /boot/config-4.15.0-140-generic | grep -i CONFIG_HISI_PMU
CONFIG_HISI_PMU=y
[Expected Results]
@ubuntu:~$ cat /boot/config-4.15.0-140-generic | grep -i CONFIG_HISI_PMU
CONFIG_HISI_PMU=m
[Reproducibility]
100%
[Additional information]
(Firmware version, kernel version, affected hardware, etc. if required):
[Resolution]
drivers/perf: hisi: Permit modular builds of HiSilicon uncore drivers
