2 | Date: Oct 2011 | |
3 | KernelVersion: 3.1 | |

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. |
