Description Ian Romanick 2014-12-22 20:31:31 UTC

We need a test case to exercise a corner case recently fixed in the i965 driver by Ken.  To exercise the bug, the test needs to do 4 things:

1. Use user-allocated vertex arrays (NOT vertex buffer objects).

2. Use a glDrawArrays with a non-zero 'first'.

3. Use primitive restart to trigger multiple _mesa_prim without an intervening state change.

4. Validate the value of gl_VertexID in the vertex shader.

Once the fix lands in Mesa master, we'll update the bug with commit ID.  That way the test author will know when the bug is fixed.

Also... this is related to Mesa bug #85529.
