Subject: [RFC PATCH v2 04/12] ARM: versatile: use remapped PPI interrupts for local timer
Date: Fri, 6 May 2011 11:33:09 +0100 [thread overview]
Message-ID: <1304677997-26947-5-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1304677997-26947-1-git-send-email-marc.zyngier@arm.com>
Use the normal interrupt scheme for the local timers by using
a remapped PPI interrupt.
Tested on VExpress and PB-11MP.
Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
