           Summary: Instanced drawing: not implemented
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: s3734770@mail.zih.tu-dresden.de


The follwing output is from the Unigine Heaven Demo:

0:171(53): error: `gl_InstanceID' undeclared
0:171(76): error: Operands to arithmetic operators must be numeric

(This also occurs on software rendering)

I know that instancing is not implemented in mesa yet. Can you please start
designing the interface for mesa/gallium's drivers to enable starting to write
the drivers for it?

The PipeCap for instanced drawing is available, the drivers implement them,
TGSI has the construct TGSI_SEMANTIC_INSTANCEID.

The only component that does not support instanced drawing is the GLSL
compiler.

So can please any of the GLSL guys implement the gl_InstanceID uniform?

Probable patch

This patch works for me, but i dont know if it fits the coding style, so take
the best bytes of it to fix the problem
