[Mesa-dev] [PATCH 00/29] blorp: Add support for more formats

[Jason Ekstrand]

This series adds additional format support to BLORP.  In particular,
BLORP's blit and copy functions now handle:

 * Source and destination swizzles on all gens
 * Blitting to RGB formats (previously we only supported copying to RGB)
 * Blitting to RGBX even if it's not supported for rendering
 * Blitting to more exotic formats such as D24_UNORM and RGB9_E5
 * Copying to and from 10_10_10_2 and 11_11_10 formats with CCS_E

As a side-effect of this, BLORP should now be capable of doing basically
all of OpenGL format conversion for texture upload.  There are still a few
edge-cases around packing and maybe luminance/alpha but most of it should
be possible.  I have no intentions of actually doing this but some
enterprising person could pick it up.

This series also does some refactoring and improving of ISL since that
seemed better than just extending everything inside blorp.  We also get a
little format conversion library for NIR out of the deal.  If we ever want
to do image_load_store lowering in NIR, most of the format conversion code
is now written.

Happy Friday!
