Subject: [Qemu-devel] [PATCH 5/6] hw/arm_gic: fix target CPUs affected by set enable/pending ops
Date: Tue, 11 Dec 2012 15:22:39 +0000 [thread overview]
Message-ID: <1355239360-29249-6-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1355239360-29249-1-git-send-email-peter.maydell@linaro.org>
From: Daniel Sangorrin <dsl@ertl.jp>
Fix a bug on the ARM GIC model where interrupts are not
set pending on the correct target CPUs when they are
triggered by writes to the Interrupt Set Enable or
Set Pending registers.
