[edk2-devel] [PATCH v3 6/7] OvmfPkg/XenPlatformPei: Calibrate APIC timer frequency

Calculate the frequency of the APIC timer that Xen provides. Even though the frequency is currently hard-coded, it isn't part of the public ABI that Xen provides and thus may change at any time. OVMF needs to determine the frequency by an other mean. Fortunately, Xen provides a way to determines
