pvusb with kernel 3.4 / 3.6

[Alexandre Bezroutchko]

[-- Attachment #1.1: Type: text/plain, Size: 703 bytes --]

Hi Nathanael,

Is it possible to use your patch [1] on newer kernels? I've tried to use it
but most devices are not usable and some cause kernel crash. Detailed
description of an attempt on kernel 3.4 is at [2] and (somewhat less
detailed) with 3.6 is at [3]. I'm motivated to make it work, any ideas what
can be done to fix this issue? Please tell me if you need any additional
info.

I've added xen-devel and Pasi Kärkkäinen into Cc, hope this is ok.

Regards,
Alex

I think Konrad has the pvusb drivers in his git tree..

Konrad's repo seems to contain the same patch [1] as published by
Nathanael. It does not work for me. I've put Konrad in Cc, hope he can
comment...

Here is my original question, please tell me what additional info you need.

pvusb with kernel 3.4 / 3.6
Hi Nathanael, 

Is it possible to use your patch [1] on newer kernels? I've tried to use it 
but most devices are not usable and some cause kernel crash. Detailed 
description of an attempt on kernel 3.4 is at [2] and (somewhat less 
detailed) with 3.6 is at [3]. I'm motivated to make it work, any ideas what 
can be done to fix this issue? Please tell me if you need any additional 
info. 

I've added xen-devel and Pasi Kärkkäinen into Cc, hope this is ok.

Have I failed to provide enough information, or there is some gross mistake
in my setup?

Could you please describe a setup for pvusb which linux 3.4 kernel and xen
4.1 having good chance to work?

I hadn't had a chance to look at it - and the only persons who would have
the expertise to do so are the authors of said patches. They seemed to
have moved on, so I think to answer your questions you would have to
wrap up your sleves and dig in the code yourself.
