[Mesa-dev] AMD RS780 please help

[EoD]

 I can confirm those results on the IGP on my M4A78T-E. I can see the
GL_EXT_transform_feedback in glxinfo.

 Hi,

would somebody with an RS780 be so kind as to test and see if
transform feedback (GL3.0 feature) works for him with r600g?

If the GL_EXT_transform_feedback extension is not exposed, you need a
newer version of kernel and/or Mesa.

To test transform feedback, run this in the piglit/bin directory:

./ext_transform_feedback-position -auto

You can get piglit here: http://cgit.freedesktop.org/piglit/

I have a fix for broken transform feedback on RS880. I just need to
know if RS780 is broken in the same way. There's a pretty high
probability that if it's broken, the cause is the same as on RS880.

Thanks.

Marek
