Re: [Xen-devel] [PATCH 2/2] x86/hvm: fix corrupt ACPI PM-Timer during live migration

Kouya, Jan,

In patch 1, pmt_update_time() calls the new function hvm_get_base_time()
which returns the frozen time when the vcpu is de-scheduled.
And I confirmed pmtimer_save() is surely called after pt_freeze_time()
from my test and review.
So, if both patches are applied, there is no difference in
delay_for_missed_ticks mode.

Okay, thanks for confirming!

Did this ever get committed? I can't immediately find a commit.

I am wondering if this is related to the ACPI timer issues we are seeing
on migration in qemu-upstream DM.
