[Mesa-dev] [PATCH v2 0/7] Split blorp blits; Enable 16k render target on gen7+

[Jordan Justen]

git://people.freedesktop.org/~jljusten/mesa split-blorp-blit-v2

(These patches have been applied on top of my ISL surface dumping
patches which are included in the branch above.)

v1:
 https://lists.freedesktop.org/archives/mesa-dev/2016-November/136235.html

v2:
 * Simplify the logic to shrink the surface by moving the RGB=>R
   conversion for blorp_copy to happen after the surface shrinking.
   (Jason)
 * Use doubles during the splitting calculations. (Jason)

This series allows large blorp blits to be split into multiple smaller
blits.

For Haswell, this fixes some OpenGL ES 3.1 CTS tests with stencil.

For gen7+ we also increase the maximum texture/render target size to
16k x 16k. (Up from 8k x 8k.) Related bugzilla:
