Hi, all.

We noticed that below 2 tests passed on linux/master v5.7-rc6 but failed on v4.19 stable.

Maybe we should do a backport. ;-)

Backport of what exactly?

...

Test on v4.19.124

selftests: kvm: platform_info_test

Are these new features that the new tests are running for, or is this a regression from older 4.19.y releases?

thanks,
