Xen 4.3.2 -- nvidia binary driver possible

Xen 4.3.2 -- nvidia binary driver possible

[Georg Bege]

Hello

I'd like to ask about the possible using of the nvidia binary driver,
along with Xen on Dom0.
It's obvious not working, there are a few hits on Google regarding this,
most are however outdated.
I didn't find a clear answer if this is possible to fix or not.

I can remember that I once had this setup in an older system,
maybe something like Linux 2.6 and much older binary driver.
There was the famous "IGNORE_XEN_PRESENCE" flag - these information
seems to be outdated.
The driver compiles fine, but if I want to startx:

My system is Gentoo Linux 3.12.21 (64bit), the nvidia driver is of
337.25 revision.
I found an older hit which similar error message, however it was from
2010 and ppl did workaround by adding nopat along with the kernel -
obviously on an 32bit host system.

Maybe this is an old tale, was asked a couple of times already - as said
I couldnt really discover a clear answer about this.

regards,
Georg

Ho much ram did you allocate to dom0. I have A8 6600K and I have no issue
running kde with ati videocard. I have 4 gb of ram allocated to dom0

The most recent driver that works for me is the 319.xx series (I think 
the current latest one of those is 319.82, which is what I'm using). 
Later drivers build but cause Xorg to fail with the error you pasted.

I mentioned something like this on one of the Xen lists about 2 weeks 
ago. Switch to 319.82 driver and it should work fine. IIRC, that 
compiles fine on 3.12.xx kernels. For later kernels you'll need some 
additional patches for the nvidia driver (I can provide a patch against 
3.13 and 3.14, I am currently running a 3.14 kernel.
