EXA on R600 (AGP)

[PuckPoltergeist]

Is EXA available on R600 chips with AGP interface now? There was something on radeonhd ML, but how is the status now? Is there something where I can help to get it work, testing, error reports? I've tried it with actual git tree of radeonhd, but only got a black screen with

II) RADEONHD(0): Mapped IO @ 0xff3f0000 to 0x7ff84b449000 (size 0x00010000)
(II) RADEONHD(0): Mapped FB @ 0xd0000000 to 0x7ff837787000 (size 0x10000000)
(WW) RADEONHD(0): RHDCSInit: No CS for R600 and up yet.

this in the X-log.

AGP support still needs some additional coding in the driver, mostly a bunch of new code in drm AFAIK. Alex is trying to get the EXA corruption issues worked out on PCIE first.

Tested the initial AGP support that got into r6xx-r7xx-support, but this results in a black screen when I start kdm (mouse is visible) and X consumes 100% CPU.

OK, thanks. Could I ask you to post x log and dmesg output on pastebin or something ?

Since the logs normaly are to long to paste:

In the meantime you can use the PCIE gart if you apply this patch to the rhd driver:

Ok, I'll try. I've also tested Christians patches (http://lists.opensuse.org/radeonhd/2.../msg00350.html) but this led to screen corruptions. Will take a screenshot if it happens again.

Ok, I still get these screen corruptions:

Also X didn't survived switching to console and back. After switching back, I got a black screen again with 100% CPU used by X.

This is from the first try:

Second try I didn't switched to console but logged in to get the screenshot. After this, I removed radeon and drm kernel module and switched back to fglrx:

Those screen corruptions is not because of using AGP, but just the state of r600 support. I get the same corruptions on PCIE.

FYI agd5f just pushed fixes for all the known corruption issues.
