2010-12-17pci: add ich9 pci idAlexander Graf
We need a PCI ID for our new AHCI adapter. I just picked an ICH-9 because that's the one in the Q35 chipset. This patch adds a PCI ID define for an ICH-9 AHCI adapter. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-12-09pci: untangle pci/msi dependencyMichael S. Tsirkin
msi depends on pci but pci should not depend on msi. The only dependency we have is a recent addition of pci_msi_ functions, IMO they add little enough to open-code in the small number of users. Follow-up patches add more cleanups. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
2010-12-09pci: make command SERR bit writableIsaku Yamahata

2010-01-26PCI: Convert pci_info() to QObjectLuiz Capitulino
The returned QObject is a QList of all buses. Each bus is represented by a QDict, which has a key with a QList of all PCI devices attached to it. Each device is represented by a QDict. As has happended to other complex conversions, it's hard to split this commit as part of it are new functions which are called by each other. IMPORTANT: support for printing PCI bridge attached devices is NOT part of this commit, it's going to be added by the next commit, as it's untested.

2009-12-18pci romfiles: add property, add default to PCIDeviceInfoGerd Hoffmann
This patch adds a romfile property to the pci bus. It allows to specify a romfile to load into the rom bar of the pci device. The default value comes from a new field in PCIDeviceInfo. The property allows to change the file and also to disable the rom loading using an empty string. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-18Support PCI based option rom loadingAnthony Liguori
Currently, we preload option roms into the option rom space in memory. This prevents DDIM from functioning correctly which severely limits the number of roms we can support. This patch introduces a pci_add_option_rom() which registers the PCI_ROM_ADDRESS bar which points to our option rom. It also converts over the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this new mechanism. The result is that PXE boot functions even with three unique types of cards.
