           Summary: KMS regression in 2.6.35: Flicker and half-rendered
                    scenes in SDL games with Radeon RV770
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: marti@juffo.org


I am getting severe flickering in multiple SDL-based games with Radeon HD 4870
(RV770)

Games tested that have this problem:
* World of Goo (SDL, 32-bit)
* Frets on Fire (Python, SDL, true 3D, 64-bit)
* Aquaria (SDL, 32-bit)

----
* kernels 2.6.33.4 and 2.6.34.2 are good even with KMS enabled
* kernels 2.6.35.4 with KMS disabled is good
* kernels 2.6.35 and 2.6.35.4 with KMS enabled is bad

The problem manifests itself in substantial flickering; most frames seem to
render OK, but a couple of times every second there's an incomplete frame. The
incomplete frame looks like a half-rendered scene, with some objects missing.

Using xorg-server 1.9.0, mesa 7.8.2, xf86-video-ati-6.13.1
(also tried mesa from git)

Normally I have 2 screens attached, but this time I also tried disabling the
second screen and unplugged it entirely.

lspci:
01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4870]

glxinfo:
OpenGL renderer string: Mesa DRI R600 (RV770 9440) 20090101  TCL DRI2
OpenGL version string: 2.0 Mesa 7.8.2

This is probably vsync related.  Does updating to the latest ddx and mesa code
in git fix the issue?

Ok, I also built xf86-video-ati from git (in addition to dri2proto, libgl,
mesa) and I am still experiencing this problem.

Indeed, Mesa git fixes it; sorry I was using Mesa git with r600_dri.so from 7.8
before.
