Charlie Lao 24f64249 2020-11-16T17:55:02 Vulkan: Track specialization constant usage bit and feedback to ctx Right now context does not know which specialization constant is used by the shader. Whenever a specialization constant changes, we assume shader program is using it, we always reach into vulkan driver to ask for a new program. Instead we can track shader's usage of specialization constant so that context can utilize this information to avoid recompile pipeline program if an unused specialization constant has changed. This CL implements the plumbing the usage bits form compiler to program object, it does not actually utilize the usage bits to avoid unnecessary compilation yet.

Charlie Lao 3f18ad09 2020-11-11T14:12:18 Vulkan: Factor out DriverUniform code to tree_utils/DriverUniform.cpp The driver uniform code is used by various tree_ops functions. But all driver uniform code are defined and implemented in the TranslatorVulkan.cpp file. There is dependency rule that tree_ops code can not call into vulkan specific function. Right now we are working around this problem by always having TranslatorVulkan creates uniform and pass it down to tree_ops. This creates inefficiency for cases that dFdy/dFdx where we don't know if we will need the driver uniform or not, until we walk the tree and see the dFdx node. This CL refactors driver uniform code into its own file and class under tree_utils so that everybody can use. Mean time we can also make it much easier for metal to expand it to have its own uniform structure.

Mohan Maiya 7bbe497a 2020-10-16T14:46:45 Vulkan: Implement EXT_texture_sRGB_decode Implement EXT_texture_sRGB_decode. This builds on the existing functionality from EXT_texture_sRGB_override, with 2 major edge cases: 1. sRGB_decode allows the texture state to be overridden by sampler state, which is implemented by forcing a a texture state sync during updateActiveTextures if a texture is bound to the same unit as a sampler with that state 2. texelFetch calls require us to reenable decoding, regardless of decode state. We add a new compiler pass (FlagSamplersWithTexelFetch) to mark samplers that are used with texelFetch in order to support this. This change also re-enables EXT_texture_sRGB_R8, which was disabled due to a dEQP bug that this change will bypass.

Ian Elliott e488d8b8 2020-02-26T16:11:29 Vulkan: Implement Android pre-rotation As an Android GLES driver on top of Vulkan, ANGLE must pre-rotate rendering on behalf of the application. This involves modifying the vertex shader to multiply gl_Position with a mat2 "rotation matrix". Not doing so means that SurfaceFlinger (SF) will perform a costly rotation blit before presenting every image. Setting WindowSurfaceVk::mPreTransform to mCurrentTransform tells SF to not do the blit. When the surface is rotated 90 or 270 degrees, the width and height must be swapped for: - The swapchain images, and for any depth, stencil, and/or multisample attachments used with the swapchain image. - The viewport, scissor, and render area. Because the Metal back-end shares the TranslatorVulkan, it will define the same preRotation (mat2) DriverUniform that is used for Vulkan.

According to the spec this is allowed. From GLSLangSpec 4.50 section 4.7 "Precision and Precision Qualifiers": For the purposes of determining if an output from one shader stage matches an input of the next stage, the precision qualifier need not match. However, when converted to SPIR-V and run through the shader validation any mismatches will cause shader validation errors. Initially just ignoring those errors with this commit.

Shahbaz Youssefi 453926f5 2020-01-19T14:49:32 Vulkan: Remove inactive shader inputs in the translator Inactive vertex attributes are harmless to remove. Between two consecutive stages, the input varyings must be a subset of the previous stage's output varyings. This means removing inactive input varyings is also harmless. Removing inactive output varyings is not possible though. GLSL allows a varying to not be written by the previous stage even if it's used in the current stage (values will be undefined, but it's not an error). This means that an inactive output varying may still need to exist as part of the shader interface in case the following stage has that varying as input (and is active).

This was due to glslang compile failures in some shaders that included mixed row- and column-major fields in interface blocks. However, the failures were only in the case the interface block is inactive, in which case glslang wrapper previously replaced the layout/qualifier of the interface block with |struct|, which left the shader with an unused struct definition with fields that have layout qualifiers; an invalid shader. The change introduced in https://chromium-review.googlesource.com/c/angle/angle/+/1951523 removes inactive shader interface declarations. The above scenario thus never occurs, rendering the row- to column-major transformation unnecessary.

Shahbaz Youssefi 93560ef5 2019-07-25T16:13:02 Vulkan: Seamful cube map emulation In GLSL, a cube texture is sampled with one of textureCube* functions. This function takes a 3D coordinate which is a vector from the center of the cube and identifies a direction to sample from. GLES2.0 has the following table that translates this 3D coordinate (Rx, Ry, Rz) to a face and ST coordinates within that face. This table can be found in Section 3.7.5 (Cube Map Texture Selection). A compiler pass is implemented in ANGLE that replaces samplerCube declarations with a sampler2DArray. The textureCube* functions are replaced with the corresponding texture* functions with the translated coordinates according to that table. Gradients provided to textureCubeGrad are translated using the same formulae, which is not precise but the spec specifies this projection to be implementation dependent. Helper invocations enabled through WQM (whole quad mode) cause a nuisance in that the extrapolated varyings used as coordinates in a textureCube call could have a different major axis (and therefore face) from the non-helper invocations that lie within the geometry. subgroupQuadSwap* operations are used in conjunction with gl_HelperInvocation to make sure the helper threads calculate texture UVs in the same face as the non-helper invocations.

Shahbaz Youssefi c13ca2af 2019-07-17T15:46:29 Vulkan: Allow more than one atomic counter buffer binding dEQP assumes there are more than one atomic counter buffers available. This is technically not a requirement by the standard, but nevertheless could be what applications expect as well. This change adds support for multiple atomic counter buffer bindings. This is done by declaring an array of storage buffers for the atomic counter buffers (instead of declaring only one) and passing the (binding, offset) pair around to functions instead of just the offset. The atomic counter is found by indexing `binding` into the storage buffer array first before indexing `offset` into its `uint[]`. ProgramVk's default uniform collection is also fixed not to include atomic counter uniforms. A remaining issue is that atomic counter buffer offsets don't have alignment requirements in GLES, but Vulkan does for storage buffers. Similar to emulated transform feedback buffer offsets, these should be sent to the shader through uniform values. This will be done in a follow up change.

Shahbaz Youssefi b82d8633 2019-07-15T11:23:08 Vulkan: Atomic counter buffer support Vulkan doesn't treat atomic counters especially, and they are emulated with atomic access to storage buffers. A single atomic counter buffer binding per pipeline is supported. All the atomic counters identify an offset within this buffer. The shader is modified to include a storage buffer definition with `uint counters[];` as the only field. A compiler pass replaces atomic counter definitions with variables that hold the corresponding offset parameter, as well as changing atomic_uint types to just uint (as the offset). Where an atomic counter variable is used, it is replaced with the offset variable (plus the array index, if array). At the same time, built-in `atomicCounter*` functions are replaced with a corresponding `atomic*` function and `memoryBarrierAtomicCounter` is replaced with `memoryBarrierBuffer`.

Jamie Madill 76e471e9 2017-10-21T09:56:01 Vulkan: Implement basic uniforms. This implementation adds one descriptor set with two bindings: one for default vertex uniforms and the other for fragment. It adds two corresponding uniform buffers, and the logic for updating the descriptor sets bound to Vulkan. It doesn't handle much in the way of synchronization and dependency management, or uniform update. If there are only vertex or fragment uniforms the empty uniform buffer is omitted from the descriptor set. If both are missing, there is no descriptor set bound. Note that as our implementation progresses we might not be able to initialize our descriptor sets at link time, due to streaming in uniform data.

Jamie Madill 6276b922 2017-09-25T02:35:57 Vulkan: Implement basic uniform shader parsing. This is a first step at implementing uniforms with descriptor sets. It does not actually bind uniforms and upload data, but it does implement uniform shader parsing. Uniforms are gathered into a single uniform block which is bound to set 0, with binding 0 for vertex uniforms and binding 1 for fragment uniforms. Also adds a ReplaceSubstring helper to string_utils. Also removes the precision writing from OutputVulkanGLSL since this was generating warnings with glslang.

Jamie Madill e794cd86 2017-01-13T17:29:51 Vulkan: Implement new GLSL translator back-end. The Vulkan GLSL translator back-end will handle validating and translating our WebGL/ESSL shaders into Vulkan-specific GLSL. glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders as inputs, and both the desktop and ESSL back-ends give incompleteness warnings when used. For now, use the desktop GL 450 as a target for Vulkan GLSL. The Vulkan-specific changes are currently only to add locations to every vertex input and fragment output.
