These control how the invocations are arranged in a CS when doing derivative and related operations (which are also enabled by the extension). Since we expect valid SPIR-V, we don't need to do more work at SPIR-V level to enable the derivative and related operations to be called.

* nir: Add ability for shaders to use window space coordinates.Timur Kristóf2019-03-051-0/+3
| | | | | | | | | | | | | This patch adds a shader_info field that tells the driver to use window space coordinates for a given vertex shader. It also enables this feature in radeonsi (the only NIR-capable driver that supported it in TGSI), and makes tgsi_to_nir aware of it.

* nir, glsl: move pixel_center_integer/origin_upper_left to shader_info.fsAlejandro Piñeiro2019-02-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On GLSL that info is set as a layout qualifier when redeclaring gl_FragCoord, so somehow tied to a specific variable. But in practice, they behave as a global of the shader. On ARB programs they are set using a global OPTION (defined at ARB_fragment_coord_conventions), and on SPIR-V using ExecutionModes, that are also not tied specifically to the builtin. This patch moves that info from nir variable and ir variable to nir shader and gl_program shader_info respectively, so the map is more similar to SPIR-V, and ARB programs, instead of more similar to GLSL. FWIW, shader_info.fs already had pixel_center_integer, so this change also removes some redundancy. Also, as struct gl_program also includes a shader_info, we removed gl_program::OriginUpperLeft and PixelCenterInteger, as it would be superfluous. This change was needed because recently spirv_to_nir changed the order in which execution modes and variables are handled, so the variables didn't get the correct values. Now the info is set on the shader itself, and we don't need to go back to the builtin variable to set it. Fixes: e68871f6a ("spirv: Handle constants and types before execution modes") v2: (Jason) * glsl_to_nir: get the info before glsl_to_nir, while all the rest of the info gathering is happening * prog_to_nir: gather the info on a general info-gathering pass, not on variable setup. v3: (Jason) * Squash with the patch that removes that info from ir variable * anv: assert that OriginUpperLeft is true. It should be already set by spirv_to_nir. * blorp: set origin_upper_left on its core "compile fragment shader", not just on some specific places (for this we added an helper on a previous patch). * prog_to_nir: no need to gather specifically this fragcoord modes as the full gl_program shader_info is copied. * spirv_to_nir: assert that we are a fragment shader when handling this execution modes. v4: (reported by failing gitlab pipeline #18750) * state_tracker: update too due changes on ir.h/gl_program v5: * blorp: minor change after change on previous patch * radeonsi: update due this change. v6: (Timothy Arceri) * prog_to_nir: remove extra whitespace * shader_info: don't use :1 on origin_upper_left * glsl: program.fs.origin_upper_left/pixel_center_integer can be move out of the shader list loop
* nir: Gather texture bitmasks in gl_nir_lower_samplers_as_deref.Kenneth Graunke2019-02-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Eric and I would like a bitmask of which samplers are used, similar to prog->SamplersUsed, but available in NIR. The linker uses SamplersUsed for resource limit checking, but later optimizations may eliminate more samplers. So instead of propagating it through, we gather a new one. While there, we also gather the existing textures_used_by_txf bitmask. Gathering these bitfields in nir_shader_gather_info is awkward at best. The main reason is that it introduces an ordering dependency between the two passes. If gathering runs before lower_samplers_as_deref, it can't look at var->data.binding. If the driver doesn't use the full lowering to texture_index/texture_array_size (like radeonsi), then the gathering can't use those fields. Gathering might be run early /and/ late, first to get varying info, and later to update it after variant lowering. At this point, should gathering work on pre-lowered or post-lowered code? Pre-lowered is also harder due to the presence of structure types. Just doing the gathering when we do the lowering alleviates these ordering problems. This fixes ordering issues in i965 and makes the txf info gathering work for radeonsi (though they don't use it). Reviewed-by: Eric Anholt <[email protected]>
* 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).

* compiler: Move double_inputs to gl_program::DualSlotInputsJason Ekstrand2018-09-061-3/+0
| | | | | | | | | | | | | | | | | | | | | | | Previously, we had two field in shader_info: double_inputs_read and double_inputs. Presumably, the one was for all double inputs that are read and the other is all that exist. However, because nir_gather_info regenerates these two values, there is a possibility, if a variable gets deleted, that the value of double_inputs could change over time. This is a problem because double_inputs is used to remap the input locations to a two-slot-per-dvec3/4 scheme for i965. If that mapping were to change between glsl_to_nir and back-end state setup, we would fall over when trying to map the NIR outputs back onto the GL location space. This commit changes the way slot re-mapping works. Instead of the double_inputs field in shader_info, it adds a DualSlotInputs bitfield to gl_program. By having it in gl_program, we more easily guarantee that NIR passes won't touch it after it's been set. It also makes more sense to put it in a GL data structure since it's really a mapping from GL slots to back-end and/or NIR slots and not really a NIR shader thing.

| | | | | | | | | | | | | | | | | | | | | | So now, during spirv_to_nir, it uses the capability instead of the extension. Note that we are really doing here is treating SPV_AMD_gcn_shader as other supported extensions. SPV_AMD_gcn_shader is not the first SPV extension supported. For example, the capability draw_parameters infers if the extension SPV_KHR_shader_draw_parameters is supported or not. This could be seen as counter-intuitive, and that it would be easier to define which extensions are supported, and based our checks on that, but we need to take into account that some capabilities are optional from core, and others came from new extensions. Also this commit would make the implementation of ARB_spirv_extensions easier. v2: AMD_gcn_shader capability renamed to gcn_shader (Daniel Schürmann) Reviewed-by: Daniel Schürmann <[email protected]> Reviewed-by: Bas Nieuwenhuizen <[email protected]>
