[Mesa-dev] [PATCH v4 0/6] Add support for ARB_transform_feedback_overflow_query.

[Rafael Antognolli]

This patch series implements the ARB_transform_feedback_overflow_query
extension for i965.

Changes for v4:
    - Reuse of MI_MATH calcs from hsw_queryobj.c in brw_conditional_render.c
    - Renamed a couple functions as suggested by Kenneth
    - Fallback to CPU-side conditional rendering if MI_MATH is not available.

The series is available on github here:

https://github.com/rantogno/mesa/tree/review/overflow_query-v04

There are also piglit tests available for it here:

Regards,
Rafael
