"Ask ATI" dev thread

[BlackStar]

Oops, wrong thread.

Anyway, two questions for bridgman:

1. Will fglrx RDR use the DRI2 and GEM/TTM infrastructure or will it take nvidia's route and rip everything out?

2. Can we expect OpenCL on Linux?

ow, just deleted my message because I found myself being unconstructive... but since you already replied on my post:

After battling with 9.1, I have another question: Why don't you sell ATI to someone who has a clue about writing drivers? No, no, I'm not joking. That would really help.

They opensourced it... THINK about this... read back your posts... stupid right?

1. Will fglrx RDR use the DRI2 and GEM/TTM infrastructure or will it take nvidia's route and rip everything out?

We were planning to use DRI2, but as I understand it current thinking is to bypass it and do our own implementation. We already have a good memory manager and do not plan to replace that with GEM/TTM.

2. Can we expect OpenCL on Linux?

I don't know for sure but I expect so. Linux is an important part of our Stream solutions and we expect OpenCL to become a core part of Stream.

There is no support for a1 surfaces in the open drivers & EXA, and seemingly won't be for months. Does frglx support it?

If we are already at it, are you planning to enable KMS in fglrx in the same way or will that remain an OSS-only feature?

[bridgman]

Yeah, that makes sense. AFAIK we are currently supporting 8.10 but not the prerelease 9.04 versions yet. For pre-release distros you are probably better off pulling the latest open source drivers.

[bridgman]

OK, maybe I'm confused. Your post said a Kubuntu 9.04 backport, what am I missing ?

[enderandrew]

Hybrid Crossfire

Bridgman, which cards specifically support Hybrid Crossfire?

[bridgman]

Ahh, ok, just the kernel is a backport. Got it.

Next dumb question... isn't Debian 5 Lenny, not Sid these days ? I still find that confusing, some folks talk about Sid as "master", Lenny as "testing" and Edge as "stable" on a permanent basis, but it seems more like releases flow through those branches, ie testing = Lenny today but a year from now testing might be something different. You guys probably understand that way better than I do.

There don't seem to be any inherent incompatibilities between radeon/radeonhd and Sid or Lenny; is there any chance your versions were just too old and the 6.10 patch was simply getting you a sufficiently recent driver to support your card ?

EnderAndrew; AFAIK it's just cards which have a similar 3D core, so with a 780 I think HD2400 definitely, HD34xx almost definitely, anything else probably not. The 43xx and 45xx have roughly twice the shader power of a 24xx/34xx so I don't think they would work well in Crossfire with a 780.
