From 3ed0b5123cd5a2a4f1fe4e594e7bf319e9eaf1da Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Sun, 12 Nov 2023 21:05:14 +0000 Subject: KVM: arm64: nv: Compute NV view of idregs as a one-off Now that we have a full copy of the idregs for each VM, there is no point in repainting the sysregs on each access. Instead, we can simply perform the transmation as a one-off and be done with it.
