* intel/isl: Add a helper to get a subimage surfaceJason Ekstrand2017-07-221-0/+41
| | | | | | | We already have a helper for doing this in BLORP, this just moves the logic into ISL where we can share it with other components. Reviewed-by: Lionel Landwerlin <[email protected]>

* intel/isl: Tighten up restrictions for CCS on gen7Jason Ekstrand2017-07-221-7/+23
| | | | | | | | | | It may technically be possible to enable some sort of fast-clear support for at least the base slice of a 2D array texture on gen7. However, it's not documented to work, we've never tried to do it in GL, and we have no idea what the hardware does if you turn on CCS_D with arrayed rendering. Let's just play it safe and disallow it for now. If someone really cares that much about gen7 performance, they can come along and try to get it working later.

* Revert "intel/isl: Only create a CCS buffer if the image supports rendering"Nanley Chery2017-07-071-1/+1
| | | | | | | | | This reverts commit 8aaa13467dc289d35dc7900ab9fab9a7689c4178, which was based on an incorrect assumption. Unlike the restriction placed on image views in the Vulkan API, OpenGL allows you to render to texture views whose formats differ from the originals.

* intel/isl: Add a helper for getting the byte/tile offset of a subimageJason Ekstrand2017-06-011-0/+39
| | | | | | | | | Frequently, get_image_offset_sa is combined with get_intratile_offset_sa so it makes sense to have a single helper to do both. If the caller doesn't want the intratile offsets, it can simply pass NULL and ISL will assert that they are 0. Reviewed-by: Topi Pohjolainen <[email protected]>

| | | | | | | | | | The only surface layout for which slice0 makes any sense is GEN4_2D. Move all of the slice0 stuff into isl_calc_phys_total_extent_el_gen4_2d and make the others trivially return the total size in surface elements. As a side-effect, array_pitch_el_rows is now returned from these helpers as well. Reviewed-by: Topi Pohjolainen <[email protected]>

* intel/isl: Refactor isl_calc_array_pitch_el_rowsJason Ekstrand2017-06-011-47/+46
| | | | | | | | | | | Over 90% of the function only applies to ISL_DIM_LAYOUT_GEN4_2D anyway so we can just handle the other two as special cases at the top. The two "generic" cases below the switch only apply on gen9 and above and only to 3D or CCS surfaces. This implies that they only apply to surfaces with ISL_DIM_LAYOUT_GEN4_2D. Making them look generic is a lie. Reviewed-by: Topi Pohjolainen <[email protected]>
