Subject: [PATCH 4/5] pci-ioda: Set PCI_BUS_FLAGS_MSI_REMAP for IODA host bridge
Date: Wed, 27 Apr 2016 20:43:29 +0800 [thread overview]
Message-ID: <1461761010-5452-5-git-send-email-xyjxie@linux.vnet.ibm.com> (raw)
In-Reply-To: <1461761010-5452-1-git-send-email-xyjxie@linux.vnet.ibm.com>
Any IODA host bridge have the capability of IRQ remapping.
So we set PCI_BUS_FLAGS_MSI_REMAP when this kind of host birdge
is detected.
