* intel/isl: Allow multisampling with ISL_FORMAT_HiZJason Ekstrand2016-10-032-3/+12
| | | | | | | | | | | | | 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.

| | | | | | | | | | | 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. Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Nanley Chery <[email protected]>

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.

| | | | | | | | | This reverts commit 3943888c94beca69e575b8d3d1ec7a6cbf474ee4. It turns out that commit was pretty-much bogus since it breaks binding a 3-D texture as a 2-D storage image.

* intel/isl: Ignore base_array_layer and array_len for 3D storage surfacesJason Ekstrand2016-09-131-2/+6
| | | | | | | | | | | | | | The time we want to restrict the Z range of a 3-D surface is when rendering to it. For storage surfaces, we always want he full range. However, we still need to set MinimumArrayElement and RenderTargetViewExtent to sensible values so we'll just set them to the reasonable defaults we used before we started respecting the base_array_layer and array_len. This fixes a bunch of Vulkan CTS regressions caused by 48f195d7c6483ed.

* intel/isl: Add support for RGB formats in X and Y-tiled memoryJason Ekstrand2016-09-122-14/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, using a non-linear tiling format helps improve cache locality by ensuring that neighboring pixels are usually close-by in memory. For RGB formats, this still sort-of holds, but it can also lead to rather terrible memory access patterns where a single RGB pixel value crosses a tile boundary and gets split into two pieces in different 4K pages. It also makes for some rather awkward calculations because your tile size is no longer an even multiple of surface element size. For these reasons, we chose to simply never create tiled RGB images in the Vulkan driver. The GL driver, however, is not so kind so we need to support it somehow. I briefly toyed with a couple of different schemes but this is the best one I could come up with. The fundamental problem is that a tile no longer contains an integer number of surface elements. I briefly considered a couple other options but found them wanting: 1) Using floats for the logical tile size. This leads to potential rounding error problems. 2) When presented with a RGB format, just make the tile 3-times as wide. This isn't so nice because now our tiles are no longer power-of-two size. Also, it can force the row_pitch to be larger than needed which, while not strictly a problem for ISL, causes incompatibility problems with the way the GL driver chooses surface pitches. The chosen method requires that you pay attention and not just assume that your tile_info is in the units you think it is. However, it's nice because it provides a nice "these are the units" declaration in isl_tile_info itself. Previously, the tile_info wasn't usable as a stand-alone structure because you had to also know the format. It also forces figuring out how to deal with inconsistencies between tiling and format back to the caller which is good because the two different consumers of isl_tile_info really want to deal with it differently: Computation of the surface size wants the fewest number of horizontal tiles possible while get_intratile_offset is far more concerned with things aligning nicely.

This causes problems if ISL_FORMAT_R32G32B32_FLOAT is used because it requires valign == 2; this should be okay because you can't render to that format.
