Hello,
Now that Xen 4.0.0 is out and has support for primary graphics passthru
and many people have been using it already and asking for a status update
for secondary adapter passthru I thought of opening a new thread about this.
What are the actual issues that need to be resolved to get the
secondary graphics passthru working? Probably related to VGA BIOS execution
in the guest?
How about the vBAR=pBAR stuff required for some (Nvidia) cards?
How do we get that functionality integrated so people don't need additional
patches?
Was there also a problem that a working VGA BIOS cannot be copied from some
cards
and they need to use/load it from a file?
Thanks!

btw. I've created a wiki page where we can list all the tested/working graphics
adapters:
http://wiki.xensource.com/xenwiki/XenVGAPassthroughTestedAdapters
I already added that suggestion to the 4.1 suggested features some days
ago and planned to rebase the patches to 4.0 if they need any adjustments.
One major change I'd like to see is dynamic (and thus optional)
configuration of the mem space to be mapped and the BIOS file to be used
Could you explain "dynamic configuration of the mem space to be mapped"?
do you mean MMIO memories?
(instead of configuration at compile time).
Also afair the previous patch set also had a maximum size (correct me if
I'm wrong) for the BIOS size that was to small for recent (HD4800+) ATI
devices.
What is the size of HD4800 bios? It can adjust memory map address
definitions in hvmloader to solve it.
