Marc Zyngier 9404673293 KVM: arm64: timers: Correctly handle TGE flip with CNTPOFF_EL2 ... Contrary to common belief, HCR_EL2.TGE has a direct and immediate effect on the way the EL0 physical counter is offset. Flipping TGE from 1 to 0 while at EL2 immediately changes the way the counter compared to the CVAL limit. This means that we cannot directly save/restore the guest's view of CVAL, but that we instead must treat it as if CNTPOFF didn't exist. Only in the world switch, once we figure out that we do have CNTPOFF, can we must the offset back and forth depending on the polarity of TGE.
