From 76602f45dcd92c6684ca08e7e0ae302fb832790b Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 8 Sep 2021 11:01:10 +0200 Subject: [PATCH] OvmfPkg/Microvm: use XenTimerDxe (lapic timer) Microvm has no acpi timer, so go use XenTimerDxe which uses the local apic instead. Set PcdFSBClock to 1000 MHz, which is the lapic timer frequency used by KVM.
