[Kernel-packages] [Bug 1840454] Re: kernel 5.2 disallows thermald's direct MSR writes
The patch for changing TCC offset can only be in for 5.4 kernel. Then there will be no MSR access. So the option is to take out of mainline kernel patch to avoid this or avoid workaround option.

No I think it's because kernel lockdown: commit 708822cdbcd3faab40e83a79b71617e1812a1b06 Author: Matthew Garrett Date: Mon Feb 18 12:44:59 2019 + UBUNTU: SAUCE: (efi-lockdown) x86/msr: Restrict MSR access when the kernel is locked down Writing to MSRs should not be allowed if the kernel is locked down, since it could lead to execution of arbitrary code in kernel mode. Based on a patch by Kees Cook. MSR accesses are logged for the purposes of building up a whitelist as per Alan Cox's suggestion.
