[Xen-users] GPU passthrough into linux guest / Unable to locate a BIOS ROM

[Patrick Proniewski <patpro@xxxxxxxxxx>]

Hello,

I apologize for this message, it's a bit off-topic. I'm posting here because I 
can't find a solution to my problem, and because I might find here some clever 
people to help.

I'm running a PC on VMware ESXi 5.5, running a bunch of VMs (OSX, Windows, 
Linux, FreeBSD, …). I have 3 graphics cards into that PC, all ATI Radeon, 
because Nvidia won't let you passthrough their mainstream GPUs from ESXi to a 
VM (you must buy very expansive "pro" GPU if you want to use passthrough).

GPU passthrough works very nicely in OSX and Windows, because those two OSes 
have proprietary drivers. And now you see me coming : GPU passthrough does not 
work on recent Linux, because official ATI drivers (fglrx) are no longer 
supported. The card is here, detected, but the OS fails to initialize it and of 
course to use it.

So I wonder if there is something in XEN that I could try & implement on my 
Linux guest to make things work.

I've even tried a kernel patch that is supposed to load the graphics card BIOS 
from a file in the system, but it failed (may be my BIOS dump was not good, I 
have no clue).

You'll find my adventures here:

Again, sorry for the off-topic, I hope some of you with deep knowledge of 
kernel/drivers/passthrough will be able to help.

thanks,
patpro
