Subject: [PATCH RFC v2 0/3] Move RTC interrupt injection back into the vpt code.
Date: Fri, 14 Feb 2014 19:51:58 +0000 [thread overview]
Message-ID: <1392407521-19884-1-git-send-email-andrew.cooper3@citrix.com> (raw)
Hi,
This series implements the most recent idea Tim was proposing about
reworking the RTC PF interrupt injection.
Patch 1 switches handling the !PIE case to calculate the right answer
for REG_C.PF on demand rather than running the timers.
Patch 2 switches back to the old model of having the vpt code control
the timer interrupt injection; this is the fix for the w2k3 hang.
Patch 3 is just a minor cleanup, and not particularly necessary.
v2 now appears to work correctly, given my dev testing. I am setting XenRT up
over the weekend to give it some thorough testing.
~Andrew
