Hi, Here are 2 patches I am thinking of sending with next coresched series. Let me know what you think. These are for not slowing down certain AMD devices if they don't have vulnerabilities that require coresched.
1/2 - keep coresched disabled if device doesn't have vulnerability. 2/2 - add debug information.
In the future, if needed we could add more options to make it possible to force-enable coresched. But right now I don't see a need for that, till a usecase arises.
Joel Fernandes (Google) (2): x86/bugs: Disable coresched on hardware that does not need it sched/debug: Add debug information about whether coresched is enabled
