Subject: [RFC v5 0/5] HPET fix interrupt logic
Date: Wed, 5 Mar 2014 15:43:41 +0000 [thread overview]
Message-ID: <1394034226-14327-1-git-send-email-andrew.cooper3@citrix.com> (raw)
This is v5 of the HPET series. It comes with a folded bugfix which prevents
the use of the legacy channel spinlock before it is initalised, and
substantial reworking of the hpet selection logic in the case of no channels
being free. This avoids a possiblity of sleeping forever when using certain
cpu-idle routines. As a result, Reviewed-by tags for the main patch have been
dropped.
Patch 1 is some pre cleanup which was brought forward from the main patch.
Patch 2 is the main chunk of work.
Patch 3 is some post cleanup which could be deferred.
Patches 4 and 5 are just debugging code.
