[Mesa-dev] [PATCH 10/14] radeonsi: add new SDMA texture copy code
Marek Olšák
maraeo at gmail.com
Wed May 4 23:43:39 UTC 2016
From: Marek Olšák <marek.olsak at amd.com>
This implements:
- Linear-to-linear partial copies. (unaligned)
- Tiled-to-linear and linear-to-tiled partial copies.
(unaligned except 1-2 Bpp)
- Tiled-to-tiled partial copies aligned to 8x8.
