No known fixed tests, but it looks like a typo from:

isl: prefix non-static API with isl_

The rest of ISL already follows this approach. Be consistent and resolve
the final references.

intel/isl: Handle HiZ and CCS tiling more directly

2016-10-03T21:53:01+00:00

The HiZ and CCS tiling formats are always used for HiZ and CCS surfaces
respectively.  There's no reason why we should go through filter_tiling and
it's much easier to always get HiZ and CCS right if we just handle them
directly.

intel/isl: Allow multisampling with ISL_FORMAT_HiZ

2016-10-03T21:53:01+00:00

HiZ buffers can be multisampled and, on Broadwell and earlier, simply using
interleaved multisampling with a compression block size of 8x4 samples
yields the correct HiZ surface size calculations.  Unfortunately,
choose_msaa_layout was rejecting multisampled HiZ buffers because of format
checks.  Now that we have a simple helper for determining if a format
supports multisampling, that's an easy enough issue to fix.

intel/isl: Allow creation of 1-D compressed textures

2016-10-03T21:53:01+00:00

Compressed 1-D textures are not well-defined thing in either GL or Vulkan.
However, auxiliary surfaces are treated as compressed textures in ISL and
we can do HiZ and CCS with 1-D so we need to be able to create them.  In
order to prevent actually using them (the docs say no), we assert in the
state setup code.

intel/isl: Fix up asserts in calc_phys_level0_extent_sa

2016-10-03T21:53:01+00:00

The assertion that a format is uncompressed in the multisample layouts
isn't quite right.  What we really want to assert is that the format
supports multisampling which is a bit more complicated query.  We also want
to assert that it has a block size of 1x1 since we do nothing with the
block size in the phys_level0_sa assignment.

isl: Finish tiling filtering for Gen6.

2016-09-16T04:21:50+00:00

Gen6 only has one additional restriction over Gen7+, so we just add it
to the existing gen7 function (which actually covers later gens too).

This should stop FINISHME spew when running GL on Sandybridge.

v2: Fix bytes per block vs. bits per block confusion (Jason) and
    rename function to gen6_filter_tiling (Jason and Chad).
