Subject: [Qemu-devel] [PATCH 0/3] pci: disable intx on flr/bus reset
Date: Thu, 20 Jan 2011 16:21:37 +0900 [thread overview]
Message-ID: <cover.1295507931.git.yamahata@valinux.co.jp> (raw)
So far pci_device_reset() is used for system reset.
In that case, interrupt controller is also reset so that
all irq is are deasserted.
But now pci bus reset/flr is supported, and in that case irq needs to be
disabled explicitly.
Isaku Yamahata (3):
pci: deassert intx on reset.
msi: simply write config a bit.
msix: simply write config
