There two important sysfs nodes that provide a mechanism to view specifics on
quirks and permissive devices:
- /sys/bus/drivers/pciback/permissive
Use cat on this file to view a list of permissive slots.
- /sys/bus/drivers/pciback/quirks
Use cat on this file view a hierarchical view of devices bound to the
PCI backend, their PCI vendor/device ID, and any quirks that are associated with
that particular slot.
You may notice that every device bound to the PCI backend has 17 quirks standard
"quirks" regardless of xend-pci-quirks.sxp. These default entries are
necessary to support interactions between the PCI bus manager and the device bound
to it. Even non-quirky devices should have these standard entries.
In this case, preference was given to accuracy over aesthetics by choosing to
show the standard quirks in the quirks list rather than hide them from the
inquiring user
