Assuming that it will, can lockdown be disabled ?
AFAIK, only by disabling secure boot completely.
I have Secure Boot enabled. I do not absolutely need it so will be able to disable it. But there are people that really need Secure Boot and won't be able to disable it.
I need the write to MSR functionality to undervolt the CPU of my laptop.
How do you do that?
I use the intel-undervolt package that I maintain: https://build.openbuildservice.org/package/show/hardware/intel-undervolt Most undervolting tools do it by manipulating MSRs. Lockdown will break them.
