5Description:
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
12 #echo 00:19.0-E0:2:FF > /sys/bus/pci/drivers/pciback/quirks
13
14 will allow the guest to read and write to the configuration
15 register 0x0E.

21Description:
22 List of devices which can have interrupt control flag (INTx,
23 MSI, MSI-X) set by a connected guest. It is meant to be set
24 only when the guest is a stubdomain hosting device model (qemu)
25 and the actual device is assigned to a HVM. It is not safe
26 (similar to permissive attribute) to set for a devices assigned
27 to a PV guest. The device is automatically removed from this
28 list when the connected pcifront terminates.
