TEE proposal for M-mode SMEP/SMAP via PMP


Andrew Waterman
 

PrivArch folks,

The TEE TG has proposed additional PMP functionality to mitigate some forms of security attack against M-mode.  A description of the threat model and the proposed augmentation is at the link below.  Please review and provide feedback on this thread; I'll do the same shortly.


Thanks,
Andrew

I’ve been keeping track of it, and I’m pretty happy with it.
