[Xen-devel] Return the PCIBACK device and script on power_off
Dear all:
There is a script to hide device and bind to pciback driver on the
Xen wiki
and it is usually used for pci passthrough.
I have two questions as follow.
1) But sometimes I want to return these (hidden) device to the original
driver,
how can I do?
For example, I have a intel audio device which is using "HDA Intel"
driver in original.
I try to echo device to the files under the driver directory, i.e.
new_slot and bind,
but there is no "new_slot" under the directory.
(/sys/bus/pci/drivers/HDA Intel/)
2) When a domain is power_off, can I do any script ?
There are only some options under the domain script, e.g. destroy,
restart, preserve, etc.
I want to return the hidden device after the domain destroy or poweroff.
Best Regards,
Tang-Hsun
