2010-12-22pcie: add flr supportIsaku Yamahata
Support flr: trigger device reset on flr config write. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Michael S. Tsirkin <mst@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>

2010-10-27pcie: update satus on resetMichael S. Tsirkin
Reset never triggers a new event, so it's enough to update status. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-10-27pcie: clean up hot plug notificationMichael S. Tsirkin
Simplify logic for hotplug notification, by tracking state of the logical interrupt condition. We then simply use this variable to make the interrupt decision, according to spec. API is made cleaner as we no longer force users to pass in old slot control value. Includes fixes by Isaku Yamahata. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>

2010-10-27Introduce range.hBlue Swirl
Extract range functions from pci.h. These will be used by later patches by non-PCI devices. Adjust current users. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> (cherry picked from commit bf1b00712375bea65f2254dea8281fa646eebbd5)
