Hey,
This small series expands from v1 with one more patch:
Patch 1) Fix affinity changes to already-in-guest-mode IRTEs which would
otherwise be nops.
Patch 2) Handle the GALog overflow condition by restarting it
I have a follow-up 3-patch series but being an potential optimization[0]
I prefer making it separate. This series just tackles bugs.
Comments appreciated.
Thanks,
Joao
Changes since v1[1]:
