Bug ID: 87611
Summary: Exercise gl_VertexID corner cases in i965 driver
Product: piglit
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: tests
Assignee: [email protected]
Reporter: [email protected]

CC: [email protected], [email protected]
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.
