[Mesa-stable] [PATCH] nv50, nvc0: fix buffer clearing to respect engine alignment requirements

Ilia Mirkin imirkin at alum.mit.edu
Sat Jan 30 16:10:07 CET 2016


It appears that the nvidia render engine is quite picky when it comes to
linear surfaces. It doesn't like non-256-byte aligned offsets, and
apparently doesn't even do non-256-byte strides.

This makes arb_clear_buffer_object-unaligned pass on both nv50 and nvc0.

As a side-effect this also allows RGB32 clears to work via GPU data
upload instead of synchronizing the buffer to the CPU (nvc0 only).
