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.

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