Patch series available in this git branch: git://xenbits.xen.org/people/aperard/ovmf.git br.apic-timer-freq-v3
Changes in v3: - typos and codying style Changes in v2: - main change is to allow mapping of Xen pages outside of the RAM see patch: "OvmfPkg/XenPlatformPei: Map extra physical address" - that new function allows to map the Xen shared info page (where we can find information about tsc frequency) at the highest physical address allowed. Hi, OvmfXen uses the APIC timer, but with an hard-coded frequency that may change as pointed out here: https://edk2.groups.io/g/devel/message/45185 <20190808134423.ybqg3qkpw5ucfzk4@Air-de-Roger> This series changes that so the frequency is calculated at runtime. Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=2490 There is also one cleanup patch that has nothing to do with the rest.
