Why is this a different interface than the existing ones we have today
(i.e. usbip?) Where is it documented? Do the Xen developers /
The interface definition is living in the Xen git repository for several
years now:
git://xenbits.xen.org/xen.git -> xen/include/public/io/usbif.h
That's header file, not a document describing the api here.
I suppose you want to tell me I should add something like:
Documentation/DocBook/usb/API-struct-urb.html
I can do this, of course.
It is used e.g. in SUSE's xen kernel since 2.6.18.
I am very aware of the amount of Xen crap in SuSE's kernel, don't use
that as an excuse for me to merge it to mainline :)
:-)
Wasn't meant as an excuse, just a hint why the interface can't be the
same as for usbip. We have to ensure compatibility with those kernels
and possibly other operating systems (BSD?, Windows?) which already
might be using pvUSB with a Dom0 based on the SUSE xen kernel.
