* glsl: add offset to glsl interface typeTimothy Arceri2016-03-054-0/+18
| | | | | | | | | | | | | | | | In this patch we also copy the offset value from the ast and implement offset linking rules by adding it to the record_compare() function. From Section 4.4.5 (Uniform and Shader Storage Block Layout Qualifiers) of the GLSL 4.50 spec: "Two blocks linked together in the same program with the same block name must have the exact same set of members qualified with offset and their integral-constant-expression values must be the same, or a link-time error results."

* glsl: apply compile-time rules for the offset layout qualifierTimothy Arceri2016-03-051-0/+49
| | | | | | | | | | | | | | | | | | | | | | | This implements the rules for the offset qualifier on block members. From Section 4.4.5 (Uniform and Shader Storage Block Layout Qualifiers) of the GLSL 4.50 spec: "The offset qualifier can only be used on block members of blocks declared with std140 or std430 layouts." ... "It is a compile-time error to specify an offset that is smaller than the offset of the previous member in the block or that lies within the previous member of the block." ... "The specified offset must be a multiple of the base alignment of the type of the block member it qualifies, or a compile-time error results." Reviewed-by: Edward O'Callaghan <[email protected]>

* i965: Only magnify depth for 3D textures, not array textures.Kenneth Graunke2016-03-041-1/+1
| | | | | | | | | | | | | | | | | When BaseLevel > 0, we magnify the dimensions to fill out the size of miplevels [0..BaseLevel). In particular, this was magnifying depth, thinking that the depth doubles at each level. This is perfectly reasonable for 3D textures, but dead wrong for array textures. Changing the depth != 1 condition to a target == GL_TEXTURE_3D check should make this only happen in the appropriate cases.

* i965/vec4: add opportunistic behaviour to opt_vector_float()Juan A. Suarez Romero2016-03-042-21/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | opt_vector_float() transforms several scalar MOV operations to a single vectorial MOV. This is done when those MOV covers all the components of the destination register. So something like: mov vgrf3.0.xy:D, 0D mov vgrf3.0.w:D, 1065353216D mov vgrf3.0.z:D, 0D is transformed in: mov vgrf3.0:F, [0F, 0F, 0F, 1F] But there are cases where not all the components are written. For example, in: mov vgrf2.0.x:D, 1073741824D mov vgrf3.0.xy:D, 0D mov vgrf3.0.w:D, 1065353216D mov vgrf4.0.xy:D, 1065353216D mov vgrf4.0.w:D, 0D mov vgrf6.0:UD, u4.xyzw:UD Nor vgrf3 nor vgrf4 .z components are written, so the optimization is not applied. But it could be applied anyway with the components covered, using a writemask to select the ones written. So we could transform it in: mov vgrf2.0.x:D, 1073741824D mov vgrf3.0.xyw:F, [0F, 0F, 0F, 1F] mov vgrf4.0.xyw:F, [1F, 1F, 0F, 0F] mov vgrf6.0:UD, u4.xyzw:UD This commit does precisely that: opportunistically apply opt_vector_float() when possible. total instructions in shared programs: 7124660 -> 7114784 (-0.14%) instructions in affected programs: 443078 -> 433202 (-2.23%) helped: 4998 HURT: 0 total cycles in shared programs: 64757760 -> 64728016 (-0.05%) cycles in affected programs: 1401686 -> 1371942 (-2.12%) helped: 3243 HURT: 38 v2: change vectorize_mov() signature (Matt). v3: take in account predicates (Juan). v4 [mattst88]: Update shader-db numbers.

* i965/formatquery: Add support for INTERNALFORMAT_PREFERRED queryEduardo Lima Mitev2016-03-031-0/+73
| | | | | | | | | | | | | | | | | | | | | | This pname is tricky. The spec states that an internal format should be returned, that is compatible with the passed internal format, and has at least the same precision. There is no clear API to resolve this. The closest we have (and what other drivers (i.e, NVidia proprietary) do, is to return the same internal format given as parameter. But we validate first that the passed internal format is supported by i965. To check for support, we have the TextureFormatSupported map'. But this map expects a 'mesa_format', which takes a format+typen. So, we must first "come up" with a generic type that is suited for this internal format, then get a mesa_format, and then do the validation. The cleanest solution here is to add a method that does exactly what the spec wants: a driver's preferred internal format from a given internal format. But at this point we lack a clear view of what defines this preference, and also there seems to be no API for it. Reviewed-by: Dave Airlie <[email protected]>

The possible values returned are IMAGE_CLASS_4_X_32, IMAGE_CLASS_2_X_32, IMAGE_CLASS_1_X_32, IMAGE_CLASS_4_X_16, IMAGE_CLASS_2_X_16, IMAGE_CLASS_1_X_16, IMAGE_CLASS_4_X_8, IMAGE_CLASS_2_X_8, IMAGE_CLASS_1_X_8, IMAGE_CLASS_11_11_10, and IMAGE_CLASS_10_10_10_2, which correspond to the 4x32, 2x32, 1x32, 4x16, 2x16, 1x16, 4x8, 2x8, 1x8, the class (a) 11/11/10 packed floating-point format, and the class (b) 10/10/10/2 packed formats, respectively. If the resource is not supported for image textures, or if image textures are not supported, NONE is returned. - IMAGE_PIXEL_FORMAT: The pixel format of the resource when used as an image texture is returned in <params>. This is the value from the /Pixel format/ column in Table 3.22. If the resource is not supported for image textures, or if image textures are not supported, NONE is returned. - IMAGE_PIXEL_TYPE: The pixel type of the resource when used as an image texture is returned in <params>. This is the value from the /Pixel type/ column in Table 3.22. If the resource is not supported for image textures, or if image textures are not supported, NONE is returned."

In this case the <internalformat> is the value of the <format> parameter that is passed to BindImageTexture. - SHADER_IMAGE_ATOMIC: The support for using the resource with atomic memory operations from shaders is written to <params>."
