Subject: [PATCH] Avoid save/restoring AMX registers to avoid a SPR erratum
|
||||
|
||||
Intel SPR erratum SPR4 says that if you trip into a vmexit while
|
||||
doing FPU save/restore, your AMX register state might misbehave...
|
||||
and by misbehave, I mean save all zeroes incorrectly, leading to
|
||||
explosions if you restore it.
|
||||
|
||||
Since we're not using AMX for anything, the simple way to avoid
|
||||
this is to just not save/restore those when we do anything, since
|
||||
we're killing preemption of any sort across our save/restores.
|
||||
|
||||
If we ever decide to use AMX, it's not clear that we have any
|
||||
way to mitigate this, on Linux...but I am not an expert.
