Subject: [PATCH 15/16] xen/x86: set VIRQ_TIMER priority to maximum
Date: Wed, 2 Oct 2013 18:15:00 +0100 [thread overview]
Message-ID: <1380734101-2991-16-git-send-email-david.vrabel@citrix.com> (raw)
In-Reply-To: <1380734101-2991-1-git-send-email-david.vrabel@citrix.com>
From: David Vrabel <dvrabel@cantab.net>
Commit bee980d9e (xen/events: Handle VIRQ_TIMER before any other hardirq
in event loop) effectively made the VIRQ_TIMER the highest priority event
when using the 2-level ABI.
Set the VIRQ_TIMER priority to the highest so this behaviour is retained
when using the FIFO-based ABI.
