Description of problem:
A user friendly way to easily understand and change the Symmetric MultiThreading hardware feature in RHEL systems is needed.
This may have dependencies on kernel parameter options yet to come, as well as additional guidance on the user interface design.
This will land in the upstream release 191. Note that the UI currently refers to https://access.redhat.com/security/vulnerabilities/L1TF , the ~ 1 year old Spectre variation. In case there will be a newer/more important variant, it's easy to change the URL to something else, of course.
I'm preparing a backport to RHEL 8.0, as Terry asked for that for z-stream: https://github.com/cockpit-project/cockpit/pull/11875
This still needs z-stream approval before the bug can be cloned for z-stream.
