* intel/isl: Rename supports_lossless_compression to supports_ccs_eJason Ekstrand2017-02-021-2/+2
| | | | | | | | | | | | | The term "lossless compression" could potentially mean multisample color compression, single-sample color compression or HiZ because they are all lossless. The term CCS_E, however, has a very precise meaning; in ISL and is only used to refer to single-sample color compression. It's also much shorter which is nice.

* intel/isl: Add support for RGB formats in X and Y-tiled memoryJason Ekstrand2016-09-121-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 should be more compact than the enum isl_channel_select[4] that we were using before. It's also very convenient because we already had such a structure in the Vulkan driver we just needed to pull it over.

* intel/isl: Treat 3-D textures as 2-D arrays for renderingJason Ekstrand2016-09-121-0/+6
| | | | | | | | | | In particular, this means that isl_view::base_array_layer and isl_view::array_len get applied to 3-D textures but only when rendering. We were already applying isl_view::base_array_layer for rendering into 3-D textures so this isn't a huge deviation.

* isl: Rework the way we define tile sizes.Jason Ekstrand2016-07-131-4/+33
| | | | | | | | | | | This is based on a very long set of discussions between Chad and myself about how we should properly represent HiZ and CCS buffers. The end result of that discussion was that a tiling actually has two different sizes, a logical size in elements, and a physical size in bytes and rows. This commit reworks ISL's pitch and size calculations to work in terms of these two sizes. Reviewed-by: Chad Versace <[email protected]>
