I'm trying to run KMS (with Plymouth) and nouveau on dual 8800GTXs and not having much (any) luck, I think the message I get is "GPU deadlock".

To get SLI support, we would need to have a developer with SLI hardware. I do not think there is a developer even with any two cards, since the bug https://bugs.freedesktop.org/show_bug.cgi?id=16897 is still open. Someone with interest in multicard or SLI support should join the project and write the code. The current status is "not implemented" and as you found out, multicard really does not work at all. SLI is another story after multicard support. -- Pekka Paalanen http://www.iki.fi/pq/ ^ permalink raw reply [flat|nested] 4+ messages in thread

I got some comments on what's needed in irc: - POSTing cards (i.e. cold boot without executing the x86 BIOS code) - maybe not VGA arbiter, maybe yes... < airlied> the only thing nouveau needs t oworry about vgaarb is if you can't disable VGA decodes < airlied> or can't discover how to disable them < airlied> in that case you need to provide a callback to disable IRQs or have a very resilient IRQ handler < airlied> that can deal with memory/io space disappearing < darktama_> the BIOS parser can cope with earlier cards apparently, I started looking at making G8x work today < marcheu> yeah it works for resume, which is virtually the same < marcheu> but since we have other bugs, we can't have multi-card support ATM :) Since I'm not familiar with this topic, I leave the interpretation for you. You can poke these guys on irc :-) -- Pekka Paalanen http://www.iki.fi/pq/ ^ permalink raw reply [flat|nested] 4+ messages in thread
