From 23fe2b3f9e7df8da53ac1bc32c6875254911d7f4 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Sun, 1 Sep 2013 11:03:45 +0300 Subject: virtio_pci: fix level interrupts with irqfd commit 62c96360ae7f2c7a8b029277fbb7cb082fdef7fd virtio-pci: fix level interrupts only helps systems without irqfd: on systems with irqfd support we passed in flag requesting irqfd even when msix is disabled. As a result, for level interrupts we didn't install an fd handler so unmasking an fd had no effect. Fix this up. Cc: qemu-stable@nongnu.org Signed-off-by: Michael S.
