What: /sys/bus/pci/drivers/pciback/quirks
Date: Oct 2011
KernelVersion: 3.1
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.
