From 2b4825a8694018901e641ccc2eafd0fff58d1415 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 30 Mar 2023 18:47:44 +0100 Subject: KVM: arm64: timers: Use CNTPOFF_EL2 to offset the physical timer With ECV and CNTPOFF_EL2, it is very easy to offer an offset for the physical timer. So let's do just that. Nothing can set the offset yet, so this should have no effect whatsoever (famous last words...).
