Le Quyen a48f95ab 2019-10-14T14:49:49 Move Vulkan GlslangWrapper code to a shared location. Metal backend will reuse Vulkan's GlslangWrapper code. The Metal backend will use this code to translate glsl to spirv then cross compile to Metal Shading Language using spirv-cross. So the source code of GlslangWrapper should be moved outside vulkan folder.

Jamie Madill f10bf6bf 2019-09-26T10:27:18 Vulkan: Implement multi-threaded GL. The main component of this change is to make vk::BufferHelper, vk::ImageHelper and vk::SyncHelper use a common path. We introduce a new "vk::SharedGarbage" helper class that stores small lists of garbage from individual objects like an ImageHelper or BufferHelper. The SharedGarbage is stored in the RendererVk with the ResourceUse of the helper object. The ResourceUse tells RendererVk when it is safe to destroy the GarbageObjects. New "onGraphAccess" commands are added in a few places to enable the common garbage collection path. A couple Context-only resources like default attributes now are referenced where they were not before. Also reorganizes some functions so we can add a few helpful ASSERTs to our graph dependencies. Added "updateCurrentAccessNodes" for this. Also adds a "RendererScoped" helper to replace many uses of "ContextScoped". The multithreading EGL tests mostly pass but have some remaining flakiness so cannot yet be enabled.

Jamie Madill b540da89 2019-09-19T14:19:12 Vulkan: Use ResourceUse to track object lifetime. With the new resource tracking scheme the CommandGraph, tracking a "Context serial" aka "current" serial is no longer necessary for CommandGraphResources. Serial tracking has been moved to the shared ResourceUse struct that gets updated on a command submission. Thus we don't need to store the serial as a current separate piece of info in BufferHelper/ImageHelper. Will lead to further redesign for the multi-threading support for Vulkan.

James Dong 1d5aaa6c 2019-08-06T11:20:13 Vulkan: support dynamic indices in array of arrays Expands existing struct-sampler rewrite to flatten arrays of arrays. This allows us to support dynamically-uniform array indexing, which is core in ES 3.2. Samplers inside (possibly nested) structs are broken apart as before, and then if the type resulting from merging the array sizes of the field and its containing structs is an array of array, the array is flattened. Also adds an offset parameter to functions taking in arrays to account for this translation. As a result of outer array sizes leaking into function signatures, functions taking arrays of different sizes are duplicated according to how the function is invoked.

When samplers are dirty, a corresponding Vulkan sampler object will be created with associated state and textures are flagged as dirty anytime sampler bindings change. Then when handling textures dirty, any bound sampler objects are pulled from active texture units. When sampler objects are bound, their state is used instead of the built-in texture's sampler state. This change also adds a test that uses the same texture object with different sampler objects to test a corner case that dEQP misses.

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.

Buffers are added to the free list when the retained buffers are released. They are taken from the free list when we allocate a new buffer. We only allocate a new buffer in the ring when we run out of free buffers. This reduces the amount of time we spend in allocation for frequent updates. Now that we're recycling buffers inside of DynamicBuffer we also need to be a bit more careful about when we allow ourselves to reuse them. If they're still in use by the GPU we should not try to modify them.

Jamie Madill 88596bea 2019-06-13T14:17:48 Vulkan: Implement a texture descriptor cache. We noticed a significant hotspot in vkAllocateDesctiptorSets. The app was repeatedly cycling through a few combinations of active textures. For each state change in ANGLE we were allocating a new desctiptor set. This in turn would trigger internal driver memory allocation and cause jank. Using a cache avoids allocations entirely since the application is rotating through a stable set of textures. The descriptor cache is stored in each program. It is indexed by a set of 32-bit serials. Each texture generates a unique serial for every combination of VkImage and VkSampler that the texture owns. The texture descriptor is refreshed every time a texture changes or is rebound. The descriptor cache is accessed via an unoredered map with the texture serial sets as the hash key. We also store the maximum active texture index in the cache key so we don't need to hash and memcmp on all 64 active textures. This will currently fail if more than MAX_UINT serials are generated. But that number is high enough that it shouldn't be possible to hit in practice in a practical amount of time. Requires shifting the texture sync to ContextVk so we can get the new serial after the textures are updated. And to make sure to update the image layouts even if the descriptors are not dirty. Improves performance of the T-Rex demo. Also improves the score of the texture state change microbenchmark by about 40%.

Jamie Madill 266a9e8d 2019-06-05T15:15:10 Vulkan: Move descriptor pools into ProgramVk. Previously ContextVk owned the descriptor pools. We were trying to maximize descriptor reuse to conserve memory. However the default uniforms would have no possible sharing. And because uniform buffers are usually unique to a program it's likely there would be less reuse. Image descriptors could be shared. But with the advent of a descriptor cache in the Program it becomes difficult to manage the cache through descriptor pool recycling. Moving the pools into the Program simplifies the cache management. We could look at adding back more reuse in the future. Also shifts driver uniforms back into the end of the descriptor sets to make indexing into the Program's descriptor pools simpler.

However, we store the uniform data transposed and row-major in d3d to accomodate the fact that matrix indexing in HLSL is the opposite of GLSL (mat[row][col] in HLSL as opposed to mat[col][row] in GLSL). There were two functions that copied the source matrix fields either as column-major or source-major (corresponding to `transpose` false or true respectively in glUniformMatrix*) into a row-major destination. These functions are refactored into one, which copies from any-major source to any-major destination. The HLSL backend uses the "to row-major" variant and the Vulkan backend uses the "to column-major" variant.

Additionally, the barrier access masks were inferred from the layout. This incurred two inefficiencies: - The src pipeline stage mask often included all stages, causing unnecessarily heavy barriers. - The access masks included all possible accesses by a layout, which in some cases was overkill, like VK_ACCESS_MEMORY_WRITE_BIT for VK_IMAGE_LAYOUT_GENERAL (which will eventually used for compute shader output). This change instead creates an enum where each element represents the layout, the stage and access masks when transitioning into the layout and the stage and access masks when transitioning out of that layout. The image will instead track a value of this enum (instead of VkImageLayout), which allows it to create the layout transition barriers as tight as possible, since it includes all the necessary information.

Jamie Madill 4e712be2 2019-01-03T13:53:59 Refactor BlockLayoutEncoder APIs for std430. This splits HLSL SSBO access into two steps. First we compute a mapping from the collected SSBO variable names to TField pointers. Then during tree traversal we use a block encoding visitor class that uses the shader names to store BlockMemberInfo structures for the structures and variables. Each nested structure is traversed separately so that the BlockMemberInfo offsets are relative to the structure start rather than the enclosing block. The array stride for a structure is the size of the struct after all the alignment is included. This gives the correct results for the SSBO access chain in the HLSL code. It also will allow us to use the same encoding and visiting logic for SSBOs on the API side.

First and foremost it reduces the size of the PipelineDesc, which is now 232 bytes. It also allows us to completely forego pipeline caches for compute shaders. We also allow sharing vertex and fragment shaders among multiple programs for internal shaders. This is good for memory savings. To allow this we keep the shaders as ref counted objects.

Jamie Madill 78bcd2be 2018-10-16T15:05:20 Vulkan: Fix deleting in-use descriptor sets. Sequences of many frames with uniform updates could lead to a bug where we attempt to delete descriptor sets that are still in use. To trigger the bug we need to write enough uniform data to trigger a descriptor set to be freed. This would correctly trigger refresh sets in the Program. But if there was a second program idle in the background that also allocated descriptors from the old pool, the bug would manifest. Fix this by storing a shared handle to the descriptor pool in the Program. The dynamic descriptor pool won't recycle descriptor pools internally unless there are zero outstanding references to the pool. We could also improve this in a resource sharing situation by keeping a single shared dynamic descriptor pool per share group. Includes a contribution from tobine@google.com that adds a test to cover the bug.

In addition, we prohibit parallel linking an active program, so that ProgramD3D does not have to worry about such similar conflicts.
