From 61fb1c54853dda9a95b785f36220fa8ff39bac20 Mon Sep 17 00:00:00 2001 From: Oliver Upton Date: Thu, 16 Sep 2021 18:15:48 +0000 Subject: selftests: KVM: Add test for KVM_{GET,SET}_CLOCK Add a selftest for the new KVM clock UAPI that was introduced. Ensure that the KVM clock is consistent between userspace and the guest, and that the difference in realtime will only ever cause the KVM clock to advance forward.
