From mboxrd@z Thu Jan 1 00:00:00 1970 From: marc.zyngier@arm.com (Marc Zyngier) Date: Thu, 12 Mar 2015 08:40:37 +0000 Subject: [PATCH 2/2] ARM: imx6: Allow GPC interrupts affinity to be changed In-Reply-To: <1426149637-22062-1-git-send-email-marc.zyngier@arm.com> References: <1426149637-22062-1-git-send-email-marc.zyngier@arm.com> Message-ID: <1426149637-22062-3-git-send-email-marc.zyngier@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org While converting the GPC code to a stacked irqchip, we lost the possibility to change the CPU affinity of an interrupt routed through the GPC. This patch restore the expected behaviour by forwarding the affinity setup to the underlying irqchip (GIC).
