[Qemu-devel] [PULL 05/20] hw/intc/arm_gic: Actually set the active bits


From: Peter Maydell
Subject: [Qemu-devel] [PULL 05/20] hw/intc/arm_gic: Actually set the active bits for active interrupts
Date: Tue, 8 Sep 2015 17:51:17 +0100

Although we were correctly handling interrupts becoming active
and then inactive, we weren't actually exposing this to the guest
by setting the 'active' flag for the interrupt, so reads
of GICD_ICACTIVERn and GICD_ISACTIVERn would generally incorrectly
return zeroes. Correct this oversight.
