Description Timo Aaltonen 2011-08-15 07:28:18 UTC
Created attachment 50234 [details] X log I've got a striped screen with a CAICOS 6779 (HD6450), running on kernel 3.0.1 or 3.1rc2, both are the same. Userland is Ubuntu Oneiric devel series, with xserver 1.10.3 and -ati snapshot from last week. Here's a call trace from dmesg (one of several identical ones): [ 10.633032] WARNING: at /home/tjaalton/linux/drivers/gpu/drm/radeon/radeon_gart.c:177 radeon_gart_bind+0x1ac/0x1c0 [radeon]() [ 10.633034] Hardware name: P5K [ 10.633034] trying to bind memory to unitialized GART !

Comment 1 Michel Dänzer 2011-08-15 07:39:14 UTC
(II) RADEON(0): GPU accel disabled or not working, using shadowfb for KMS Check the drm/radeon initialization messages in dmesg. Usually this is due to failing to load a firmware file. I guess we should handle the failure more gracefully though...
Comment 2 Timo Aaltonen 2011-08-15 07:39:22 UTC
Created attachment 50236 [details] screenshot I should probably add that the mouse cursor is a "box" which moves, so the server appears working fine. A photo attached to prove it.

Comment 5 Patrik Kullman 2011-09-06 03:20:02 UTC
I get the exact same behaviour, with pretty much the same setup. 64-bit Ubuntu Oneiric Beta1, 3.0 kernel, xorg-edgers PPA for latest drivers.
Comment 7 Patrik Kullman 2011-09-07 05:21:25 UTC
Created attachment 50959 [details] dmesg with ttm dma pool 1.7 patchset After discussion with Dave Airlie he concluded that the chipset (Intel G31 in my case) doesn't have DMAR / IOMMU and that systems with 4GB or more memory enabled SWIOTLB in those cases, which was the problem. However, booting with mem=3G or with physical memory below 4GB did not solve the problem. Disabling iommu with iommu=off only disabled the SATA-support without solving the Radeon-issue. Booting with less than 4GB of memory and iommu=off did not disable SATA-support but did not solve the issue either. I finally tried compiling the Oneiric kernel with the TTM DMA Pool 1.7 patchset from Konrad for Xen, but the ring test still failed. Reading the source I can conclude that the test writes "0xDEADBEEF" but reads "0xCAFEDEAD". Not sure how to proceed. Attaching dmesg from boot with TTM DMA Pool 1.7 patchset.
Comment 8 Alex Deucher 2011-09-07 23:07:10 UTC
Does this patch: http://lists.freedesktop.org/archives/dri-devel/2011-August/013591.html adapted for evergreen/ni chips help?
Comment 9 Patrik Kullman 2011-09-08 01:09:05 UTC
I'm not sure how to adapt it for evergreen/ni. If you'd send me such a patch I'd be happy to try it out and report back.

Sounds like the change did make a difference though... can you attach dmesg for that?

Created attachment 50969 [details] [review] Don't read from CP ring write pointer registers This patch goes further and removes any reliance on reads from those registers. Does it help?
Comment 13 Timo Aaltonen 2011-09-08 05:53:58 UTC
Created attachment 50974 [details] dmesg with the patched kernel unfortunately no, VT's still look corrupted, and starting X hangs the machine.

Created attachment 51806 [details] [review] workaround debugged on my caicos please test this patch and tell me if it works for you. If it does AMD will have to debug things from here, I just got this using old fashion if 0 bisection.
Comment 15 Patrik Kullman 2011-10-02 02:06:34 UTC
This patch, applied to latest Ubuntu Oneiric kernel, works perfectly! Performance blows fglrx out of the water and the display management is way better than the AMD CCCLE. Finally a usable desktop, thank you so much!
Comment 16 Patrik Kullman 2011-10-02 02:20:16 UTC
I have some strange issue with XVideo, though. I started playing a video with Totem and the colors were off and way too dark. Then I tried playing it with VLC and mplayer with the same result. But then I tried to play the video with the x11 output (mplayer -vo x11) which showed the correct colors, and the next try with mplayer -vo xv also had the right colors. This can be better compared in gstreamer-properties, where the test-stream for x11 looks like it should, but for xv, everything white or black is black and the rest of the colors are too dark. I had similar issues with XVideo on fglrx, where XVideo could turn completely black from time to time.
Comment 17 Alex Deucher 2011-10-02 05:54:22 UTC
(In reply to comment #16) > I have some strange issue with XVideo, though. Make sure your Xv attributes aren't adjusted strangely. Some apps set strange default values.
