Subject: [Qemu-devel] [PATCH 0/2] hw/vfio/platform: irqfd setup changes
Date: Wed, 23 Sep 2015 00:00:28 +0100 [thread overview]
Message-ID: <1442962830-7437-1-git-send-email-eric.auger@linaro.org> (raw)
This series fixes a bug related to irqfd setup for edge sensitive IRQs
and proposes a new startup sequence for irqfd signaling.
The current startup sequence brings some issues with respect to the
oncoming ARM IRQ forwarding support. The new startup sequence starts
either irqfd signaling or eventfd signaling and there is no risk the
IRQ is active nor masked when irqfd/IRQ forwarding is setup.
