[Mesa-dev] [PATCH 0/3] r600g removal of unnecessary cache flushes

[Grazvydas Ignotas]

I've patched the CS validator and there seem to be some regressions:

arb_map_buffer_range 11/11 5/11
copybuffersubdata decrement-offset
copybuffersubdata increment-offset
copybuffersubdata offset=0
map_invalidate_range_bit decrement-offset
map_invalidate_range_bit increment-offset
map_invalidate_range_bit offset=0
arb_texture_buffer_object 77/78 76/78
subdata-sync
arb_vertex_buffer_object 16/16 13/16
vbo-subdata-many drawarrays
vbo-subdata-many drawelements
vbo-subdata-many drawrangeelements

The "good" run was done on newer git master than what your
r600-opt-flushes branch is based on, don't know if it has any effect.
Should I attempt to bisect?
