Shahbaz Youssefi 203154b5 2021-01-18T10:43:07 Vulkan: Remove swiftshader workaround for missing gl_Position The following line was added by the translator to work around a swiftshader bug where no gl_PerVertex declaration (and hence no gl_Position) would fail an assertion: gl_Position = gl_Position; The swiftshader bug is fixed, so this line can be removed.

Shahbaz Youssefi ea71c6b6 2021-01-12T14:13:35 Vulkan: Emulate R32F images with R32UI GL requires that imageAtomicExchange be supported for r32f formats. However VK_FORMAT_FEATURE_STORAGE_*_ATOMIC_BIT is nearly unsupported everywhere without some Vulkan extension that brings in unnecessary support. This GL feature is emulated by transforming the shader to use r32ui for all images that originally specified r32f. floatToUintBits and uintBitsToFloat is used to maintain correct usage of the image* builtin functions.

The first transformation solely takes out the samplers out of structs, and potentially generates array of array of samplers. A second transformation is added that takes any array of array of opaque uniforms and flattens it.

Shahbaz Youssefi dc99fc40 2021-01-13T00:21:41 Vulkan: Translator pass to monomorphize problematic functions With array of array of samplers and images, we currently require the shader*ArrayDynamicIndexing Vulkan features. With atomic counters, we require the shaderStorageBufferArrayDynamicIndexing feature. The above features are required to enable passing opaque uniforms to functions. This change introduces a translator pass that monomorphizes functions that receive atomic counters, or partially subscripted array of array of samplers or images, etc by removing those arguments and using the opaque uniform directly. Follow up changes will include: - Great simplification to RewriteStructSamplers, and removal of RewriteStructSamplersOld. This will drop dependency to shaderSampledImageArrayDynamicIndexing and shaderStorageImageArrayDynamicIndexing. - Great simplification to RewriteAtomicCounters. This will drop dependency to shaderStorageBufferArrayDynamicIndexing. - Emulation of imageAtomicExchange for r32f formats, but changing the qualifier to r32ui. Note that parts of RewriteStructSampler are obsolete with this change, but will be refactored as a follow up.

An alternative solution would be to generate this transformation in the translator in every geometry stage, each controlled by a separate specialization constant. This change avoids unnecessary modifications to earlier stages. Additionally, the transformer is already modifying gl_Position.xy for pre-rotation, so the addition of a small transformation of gl_Position.z in the same spot is rather trivial.

An alternative solution would be to generate pre-rotation code in the translator in every geometry stage, each controlled by a separate specialization constant. This change avoids unnecessary modifications to earlier stages. The generated shaders are also smaller, as they don't contain a mat2[8] pre-rotation constant matrix. The SPIR-V transformer knows the pre-rotation at transformation time, so it can simply use swizzles to achieve the same results. This also ties in with upcoming changes which move gl_Position.z correction to the last geometry shader stage, which is trivially done piggy-backing on the infrastructure in this change.

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.

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.

Currently, descriptor set and binding indices are set by the transformer. The shader translator outputs arbitrary set and binding indices. Once compiled by glslang, the SPIR-V transformer modifies these decorations. The ultimate goal is to be able to modify the SPIR-V again when program pipeline objects decide a different set/binding is necessary.

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.

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.

At the same time, built-in `atomicCounter*` functions are replaced with a corresponding `atomic*` function and `memoryBarrierAtomicCounter` is replaced with `memoryBarrierBuffer`.

Shahbaz Youssefi f92fc916 2019-07-15T22:39:23 Vulkan: Compute shader support A DispatchHelper class is created as the equivalent of FramebufferHelper as a command graph resource. There's currently a single dispatcher and all dispatch calls are recorded on that. Context dirty bits are set up in such a way that graphics and compute workloads are independently handled, so that issuing a dispatch call wouldn't cause a framebuffer's render pass to rebind resources.

Shahbaz Youssefi 0bfa5504 2019-06-03T10:40:10 Vulkan: Emulate Transform Feedback with vertex shader output In ES 3.0 and 3.1, only non-indexed GL_POINTS, GL_LINES and GL_TRIANGLES is supported for transform feedback. Without tessellation and geometry shaders, we can calculate the exact location where each vertex transform output should be written on the CPU, and have each vertex shader invocation write its data separately to the appropriate location in the buffer. This depends on the vertexPipelineStoresAndAtomics Vulkan feature.
