Subject: [PATCH 0/4 v2] x86/hvm: RTC periodic timer adjustments
Date: Thu, 28 Mar 2013 16:09:26 +0000 [thread overview]
Message-ID: <1364486970-14990-1-git-send-email-tim@xen.org> (raw)
With these four patches, the time drift that was happening on Windows XP
guests goes away, at least in my testing. 3/4 is probably the most
important (with the other three, I still see slow drift), but the others
all seem like a good idea to me.
Changes since v1:
- moved the irq logic patch to the end of the queue so the others
can be applied independently
- in the irq logic, keep the strobing behaviour as before
- store period_code instead of period and pt_active
Cheers,
Tim.
