AMD Dev Proposes Dynamic Mitigations For Linux: Run-Time Toggling Of CPU Mitigations

A big patch series was posted today for the Linux kernel that would allow enabling/disabling CPU security mitigations at run-time rather than the current handling that can only be managed at boot-time via various Linux kernel command-line arguments. Thus due to changing security needs, differing workloads mandating different CPU security concerns and the like, this proposed feature would allow Spectre, Meltdown, and other CPU security mitigations to all be toggled at run-time...
