[Mesa-dev] [PATCH 39/84 v2] st/nine: Reimplement nine_context_apply_stateblock
Axel Davy

Thu Dec 15 23:54:18 UTC 2016
The new version uses nine_context functions instead of
applying the changes directly to nine_context.
This will enable it to work with CSMT.
v2: Fix nine_context_light_enable_stateblock.
The memcpy arguments were wrong, and the state
wasn't set dirty.
