Bug #: 49309 Summary: R600_STREAMOUT is broken Classification: Unclassified Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/R600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: nedanfor@gmail.com
Created attachment 60802 --> https://bugs.freedesktop.org/attachment.cgi?id=60802 glxinfo output
I use drivers from this PPA: https://launchpad.net/~oibaf/+archive/graphics-drivers/. xserver-xorg-video-ati version is 1204181041.0bda30, mesa version is 1204271238.6af4c9.
I don't know when it has started but yesterday I discovered that "OpenGL version string" reports OGL 2.1 instead of 3.0 while using R600_STREAMOUT and R600_GLSL130.
My GPU is a AMD Radeon HD6570 (TURKS Pro, Northern Islands). If you need other information, please let me know.

--- Comment #1 from Marek Olšák maraeo@gmail.com 2012-04-30 12:12:08 PDT --- So what's the issue? The GL version? There's a new requirement for GL3: 4x multisampling.

So what's the issue? The GL version? There's a new requirement for GL3: 4x multisampling.
If Matteo is interested, it's Mesa's commit 8e90913e9f99ff3296a3c3da36e73cd2d4730269 mesa: require GL_MAX_SAMPLES >= 4 for GL 3.0
As noted in commit i965: Claim to support 4 multisamples on gen6+., this was missing before.
NOTE: This is a candidate for the 8.0 branch.

So as you were pointing Marek, this is not a bug and it should be closed as so.

--- Comment #4 from Alex Deucher agd5f@yahoo.com 2012-04-30 16:34:16 PDT --- GL3 requires MSAA which is not yet supported. GL3 was mistakenly enabled without it initially. Dave has a branch with initial support which will be merged when ready: http://cgit.freedesktop.org/~airlied/mesa/log/?h=r600g-ms
