| What:           /sys/bus/pci/drivers/pciback/quirks
 | |
| Date:           Oct 2011

| KernelVersion:  3.1
 | |
| Contact:        xen-devel@lists.xenproject.org
 | |
| Description:
 | |
|                 If the permissive attribute is set, then writing a string in
 | |
|                 the format of DDDD:BB:DD.F-REG:SIZE:MASK will allow the guest
 | |
|                 to write and read from the PCI device. That is Domain:Bus:
 | |
|                 Device.Function-Register:Size:Mask (Domain is optional).
 | |
|                 For example:
 | |
|                 #echo 00:19.0-E0:2:FF > /sys/bus/pci/drivers/pciback/quirks
 | |
|                 will allow the guest to read and write to the configuration
 | |
|                 register 0x0E.
