[Mesa-dev] [PATCH 0/4] Add ETC2 block patching for HALTI0

[Christian Gmeiner]

HALTI0 GPUs have broken ETC2 support (for RGB and RGBA)
formats. The blob driver does per-block patching. The patching
is quite simple: color swaping.

This patch series adds support for the needed block patching
and enabled ETC2 support for HALTI0.

Passes all tested formats of the following piglit:
 spec/!opengl es 3.0/oes_compressed_etc2_texture-miptree_gles3

Christian Gmeiner (4):
  etnaviv: implement ETC2 block patching for HALTI0
  etnaviv: keep track of mapped bo address
  etnaviv: hook-up etc2 patching
  etnaviv: enable ETC2 texture compression support for HALTI0 GPUs
