[edk2-devel] [PATCH 0/5] OvmfXen: Set PcdFSBClock at runtime

Posted by Anthony PERARD 4 years, 2 months ago

Patch series available in this git branch:
git://xenbits.xen.org/people/aperard/ovmf.git br.apic-timer-freq-v1

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.

Cheers,
