[PATCH v3 0/3] xen/pciback: support driver_override
From: Juergen Gross
Date: Thu Sep 22 2016 - 04:46:32 EST
Support the driver_override scheme introduced with commit 782a985d7af2
("PCI: Introduce new device binding path using pci_dev.driver_override")
Today you'd need something like:
echo 0000:07:10.0 > /sys/bus/pci/devices/0000\:07\:10.0/driver/unbind
echo 0000:07:10.0 > /sys/bus/pci/drivers/pciback/new_slot
echo 0000:07:10.0 > /sys/bus/pci/drivers_probe
while with the patch you can use the same mechanism as for similar
drivers like pci-stub and vfio-pci:
echo pciback > /sys/bus/pci/devices/0000\:07\:10.0/driver_override
echo 0000:07:10.0 > /sys/bus/pci/devices/0000\:07\:10.0/driver/unbind
echo 0000:07:10.0 > /sys/bus/pci/drivers_probe
Changes in V3:
- Added new patches 1 and 2 to do some cleanup and preparatory work.
- patch 3: Add an assigned device to the slot list
- patch 3: Move override check up in order not to miss the PCI_HEADER_TYPE
check.
Changes in V2:
- Removed now unused label.
