computers are a fuck huh
somewhere a AMD engineer is smiling very smugly
LB:
"AMD processors are not subject to the types of attacks that the kernel
page table isolation feature protects against. The AMD microarchitecture
does not allow memory references, including speculative references, that
access higher privileged data when running in a lesser privileged mode
when that access would result in a page fault."
jesus Tom have some mercy
@staticsafe the speculative references bit is terrifying
@hirojin @staticsafe no, /that's/ understandable, the implication that speculative references can access higher privileged data from a lower privileged mode
@er1n @staticsafe i have just one thing to say about that
oops
@er1n @staticsafe it's nothing too unusual, how else would you keep all those pipelines constantly filled and flowing?
