I think you must set PcdFSBClock for this to work properly. When using kvm (which cloudhv does as far I know) this is simple as the frequency is fixed then, see microvm dsc file. With xen this is dynamic so the xen platform init has some code to figure the frequency and set the pcd. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
