This bug is awaiting verification that the linux/5.4.0-112.126 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
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.

There is no way to replace with a updated module unless we build it as module. It also wastes memory on arm64 systems based on other SoCs. [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 To manage notifications about this bug go to: https://bugs.launchpad.net/kunpeng920/+bug/1956086/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
