            Bug ID: 107669
           Summary: [bisected] wflinfo fails
                    ctx->Const.MaxCombinedTextureImageUnits assertion
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: maraeo at gmail.com
          Reporter: clayton.a.craft at intel.com
        QA Contact: mesa-dev at lists.freedesktop.org

$ wflinfo --platform=gbm -a gl
ERROR: command failed
STDERR: wflinfo: ../src/mesa/main/context.c:777: check_context_limits:
Assertion `ctx->Const.MaxCombinedTextureImageUnits <=
MAX_COMBINED_TEXTURE_IMAGE_UNITS' failed.


I've bisected this failure to this commit:

commit 45f87a48f94148b484961f18a4f1ccf86f066b1c (refs/bisect/bad)

    mesa: don't include compute resources in MAX_COMBINED_* limits

    5 is the maximum number of shader stages that can be used by 1 execution
    call at the same time (e.g. a draw call). The limit ensures that each
    stage can use all of its binding points.

    Compute is separate and doesn't need the 5x multiplier.
