             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

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.

So is it a missing functionality? Thank you. Sorry if I've wasted your time.

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.

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:
