There are still something already committed to mainline but missed on the list. I have to include also IceLake support for CometLake backports to D/OEM-OSP1-B, but `perf list` doesn't give PC8-10 for IceLake platforms. However, by installing v5.4-generic kernel from https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable, they're back.
