| 5 | Description: |
| 6 | If the permissive attribute is set, then writing a string in |
| 7 | the format of DDDD:BB:DD.F-REG:SIZE:MASK will allow the guest |
| 8 | to write and read from the PCI device. That is Domain:Bus: |
| 9 | Device.Function-Register:Size:Mask (Domain is optional). |
| 10 | For example: |
| 11 | #echo 00:19.0-E0:2:FF > /sys/bus/pci/drivers/pciback/quirks |
| 12 | will allow the guest to read and write to the configuration |
| 13 | register 0x0E. |
