At present, crosvm can support handle RDMSR in userspace by read MSR of Host directly. This is the RDMSR passthrough in userpace. This patch adds more MSR handler support, including: - WRMSR passthrough: write the corresponding MSR of Host directly in userspace; The control of MSR will work on host; - RDMSR emulation: crosvm uses a dummy MSR value to let Guest reads on. This value can be different with real MSR of Host; - WRMSR emulation: crosvm uses a dummy MSR value to let Guest writes into. This means the control of MSR won't really work (on Host). BUG=b:225375705 TEST=Set `--userspace-msr=0x1a2,type=r,action=pass,from=cpu0` Change-Id: I3276dd651464ef7b695e2ddd433793d59128af9b Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3575508 Reviewed-by: Junichi Uekawa <uekawa@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Junichi Uekawa <uekawa@chromium.org>
