Description Tormod Volden 2011-01-09 15:02:28 UTC

It is a M26 (RV410) card using gallium.

$ bin/glx-make-current 
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  155 (GLX)
  Minor opcode of failed request:  11 (X_GLXSwapBuffers)
  Serial number of failed request:  44
  Current serial number in output stream:  45

This is with xserver 1.9.0.902 and mesa 7.9 (Ubuntu natty). Same with latest mesa git and xserver git on 1.9 branch 2010-11-29 (Ubuntu 10.10 + xorg-edgers). When using latest mesa git but older xserver 1.7.6, the xserver itself segfaults in libglx.so.

There have been similar, fixed bugs like bug 30234 on intel and swrast, and maybe bug 20291 on intel. The piglit test was written for bug 30457.

I have no idea about this one really. Reassigning to GLX.

Comment 2 Rahul 2016-08-25 18:47:51 UTC

Is there any update over this ?
I am also facing the same issue.

Comment 3 Marek Olšák 2016-08-26 09:20:32 UTC

It looks like this is indirect rendering. Generally, you shouldn't use indirect rendering, because it's slow and limited in everything, and it breaks from time to time.

Hi Marek,

But i am seeing this issue with same piglit test.
Is it expected.. ?
is there any suggestion what is causing it ?

Thanks,
Rahul

Comment 5 Marek Olšák 2016-08-26 09:26:33 UTC

No idea. I only know indirect rendering doesn't work on my machine and the piglit test fails too. Direct rendering has always worked.

Comment 6 Rahul 2016-08-26 09:31:04 UTC

Thanks Marek,
But i believe if we can debug it .. and fix it.
I am still learning driver and will try to understand it.
