            Bug ID: 91753
           Summary: r300g: XXX
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: stefandoesinger@gmx.at
        QA Contact: dri-devel@lists.freedesktop.org

When trying to run any GL application that renders something with r300g (e.g.
glxgears) fails with the message "radeon: command stream overflowed". This is a
regression caused by the following commit:

567394112d904096abff1d994ab952f475dfb444 is the first bad commit

    radeon/winsys: increase the IB size for VM

    Luckily, there is a kernel query, so use the size from that.
    It currently returns 256KB. It can be increased in the kernel.

    Reviewed-by: Michel Dänzer <michel.daenzer@amd.com>

I am running Linux 4.1.6 (+ some Gentoo patches) and libdrm 2.4.64. The X.org
server version is 1.16.4 and the DDX driver is xf86-video-ati-7.5.0.

This commit has already been reverted and will be part of 11.0.0-rc2.

commit a83c36b5c0c64c717ced76db89bab900006648aa

    Revert "radeon/winsys: increase the IB size for VM"

    This reverts commit 567394112d904096abff1d994ab952f475dfb444.

    It regressed performance. It looks like smaller IBs are better, because
    the GPU goes idle quicker and there is less waiting for buffers and fences.

Oh, sorry for the spam then. I bisected this on Sunday and forgot to file an
actual bug report until now. I'm comping the current git code at the moment to
re-test.
