* nir: Move V3D's "the shader was TGSI, ignore FS output types" flag to NIR.Eric Anholt2019-02-051-0/+19
| | | | | | | | | | | | | | Ken's rework of mesa/st builtins to NIR means that we'll have more NIR shaders with color output types that are mismatched with the render target types. Since this is behavior that GLSL doesn't require, add it as a shader_info option so the driver can know that it needs to ignore the FS output's base type in favor of the actual render target's. This prevents needing additional variants in several mesa/st paths (clear, pbo upload, pbo download), given that the driver already has to handle the variants for any TGSI being passed to it (from u_blitter, for example).

* spirv: Rework handling of spec constant workgroup size built-insJason Ekstrand2019-02-012-4/+14
| | | | | | | | | | | Instead of handling it as part of the handling of constant instructions, just stash the vtn_value when we see the decoration and handle it explicitly later. This will let us re-order handling of constant instructions without breaking the Vulkan SPIR-V requirement that decorating a specialization constant as the WorkgroupSize built-in overrides the workgroup size set as an execution mode.

* spirv: Don't use special semantics when counting vertex attribute sizeNeil Roberts2019-01-281-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under Vulkan, the double vertex attributes take up the same size regardless of whether they are vertex inputs or any other stage interface. Under OpenGL (ARB_gl_spirv), from GLSL 4.60 spec, section 4.3.9 Interface Blocks: "It is a compile-time error to have an input block in a vertex shader or an output block in a fragment shader. These uses are reserved for future use." So we also don't need to check if it is an vertex input or not, and use false in any case. v2: (changes made by Alejandro Piñeiro) * Update required after "spirv: Handle location decorations on block interface members" own updates (original patch was sent several months ago) * After Neil suggesting it, confirm that this change can be also done for OpenGL (ARB_gl_spirv).

* spirv/nir: handle location decorations on block interface membersNeil Roberts2019-01-282-9/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the code was taking any location decoration on the block and using that to calculate the member locations for all of the members. I think this was assuming that there would only be one location decoration for the entire block. According to the Vulkan spec it is possible to add location decorations to individual members: “If the structure type is a Block but without a Location, then each of its members must have a Location decoration. If it is a Block with a Location decoration, then its members are assigned consecutive locations in declaration order, starting from the first member which is initially the Block. Any member with its own Location decoration is assigned that location. Each remaining member is assigned the location after the immediately preceding member in declaration order.” This patch makes it instead keep track of which members have been assigned an explicit location. It also has a space to store the location for the struct as a whole. Once all the decorations have been processed it iterates over each member to fill in the missing locations using the rules described above. So, this commit is needed to get working a case like this, on both Vulkan and OpenGL using SPIR-V (ARB_gl_spirv): out block { layout(location = 2) vec4 c; layout(location = 3) vec4 d; layout(location = 0) vec4 a; layout(location = 1) vec4 b; } name; v2: (changes made by Alejandro Piñeiro) * Update after introducing struct member splitting (See commit b0c643d) * Update after only exposing interface_type for blocks, not to any struct * Update after last changes done for xfb support v3: use "assign" instead of "add" on the new method added (Tapani) Signed-off-by: Neil Roberts <[email protected]> Signed-off-by: Alejandro Piñeiro <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>
* glsl: fix block member alignment validation for vec3Niklas Haas2019-01-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 7.6.2.2 (Standard Uniform Block Layout) of the GL spec says: The base offset of the first member of a structure is taken from the aligned offset of the structure itself. The base offset of all other structure members is derived by taking the offset of the last basic machine unit consumed by the previous member and adding one. The current code does not reflect this last sentence - it effectively instead aligns up the next offset up to the alignment of the previous member. This causes an issue in exactly one case: layout(std140) uniform block { layout(offset=0) vec3 var1; layout(offset=12) float var2; }; As per section 7.6.2.1 (Uniform Buffer Object Storage) and elsewhere, a vec3 consumes 3 floats, i.e. 12 basic machine units. Therefore, `var1` in the example above consumes units 0-11, with 12 being the first available offset afterwards. However, before this commit, mesa incorrectly assumes `var2` must start at offset=16 when using explicit offsets, which results in a compile-time error. Without explicit offsets, the shaders actually work fine, indicating that mesa is already correctly aligning these fields internally.

| | | | | | | | | | | | | | | | | | | | | | | | | | | In order to allow nir_gather_xfb_info to be used on OpenGL, specifically ARB_gl_spirv. So, from OpenGL 4.6 spec, section 11.1.2.1, "Output Variables": "outputs specifying both an *XfbBuffer* and an *Offset* are captured, while outputs not specifying both of these are not captured. Values are captured each time the shader writes to such a decorated object." This implies that are captured if both are present, and not if one of those are lacking. Technically, it doesn't explicitly point that having just one or the other is a mistake. In some cases, glslang is adding some extra XfbBuffer without XfbOffset around, and mentioning that technically that is not a bug (see issue#1526) And for the case of Vulkan, as the same glslang issue mentions, it is not clear if that should be a mistake or not. But even if it is a mistake, it is not really needed to be checked on the driver, and we can let the validation layers to check that. v2: simplify explicit_xfb_buffer and explicit_offset checks (Jason).
