[Mesa-dev] [RFC 00/10] Enable support for 2D ASTC HDR and LDR formats

[Nanley Chery]

From: Nanley Chery <nanley.g.chery at intel.com>

This patch series adds support for the KHR_texture_compression_astc_{ldr,hdr}
extensions. The last two commits enable support for Skylake systems.

Some rendering issues were encountered during testing, so there is some more
work to be done on this feature. The Piglit tests for this extension can be 
found here: cgit.freedesktop.org/~nchery/piglit

Nanley Chery (10):
  mesa/formats: define the 2D ASTC formats
  glapi: add support for KHR_texture_compression_astc_ldr
  mesa: disable online compression for ASTC formats
  mesa: add ASTC extensions to the extensions table
  mesa/glformats: recognize ASTC formats as compressed
  mesa/texcompress: enable translation between MESA and GL ASTC formats
  mesa/teximage: return the base internal format of the ASTC formats
  mesa/formats: store whether or not a format is sRGB in gl_format_info
  i965/surface_formats: add support for 2D ASTC surface formats
  i965: enable ASTC support for Skylake
