[PATCH for-4.17 v3 0/2] amd/virt_ssbd: refactoring and fixes

Posted by Roger Pau Monne 1 year, 6 months ago

Hello,

Just two patches remaining, and the last one is already Acked.

First patch deals with moving the switching of SSBD from guest
vm{entry,exit} to vCPU context switch, and lets Xen run with the guest
SSBD selection under some circumstances by default.

Thanks, Roger.

Roger Pau Monne (2):
  amd/virt_ssbd: set SSBD at vCPU context switch
  amd: remove VIRT_SC_MSR_HVM synthetic feature
