Message-ID: <1436156141-3674-1-git-send-email-jszhang@marvell.com> Date: Mon, 6 Jul 2015 12:15:39 +0800 From: Jisheng Zhang <jszhang@...vell.com> To: <tglx@...utronix.de>, <jason@...edaemon.net>, <linux@....linux.org.uk> CC: <linux-kernel@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, Jisheng Zhang <jszhang@...vell.com> Subject: [PATCH v3 0/2] irqchip: dw-apb-ictl: add irq_set_affinity support On Marvell Berlin SoCs, the cpu's local timer is shutdown when the cpu goes to a deep idle state, then the timer framework will be notified to use a broadcast timer instead. In our case, the broadcast timer uses dw-apb-ictl as the interrupt chip. These patches try to add irq_set_affinity support so that the going to deep idle state cpu can set the interrupt affinity of the broadcast interrupt to avoid unnecessary wakeups and IPIs. Changes since v2: - Add a DT option to indicate whether we want to set the irq affinity. Changes since v1: - Add a simple test and its result into the second patch's commit msg.
