Jamie Madill ce4918f1 2020-02-19T09:39:44 Vulkan: Sanitize Images & Buffers with non-zero values. Only enabled for specific tests at the moment. This CL allows our tests to sanitizes memory for the robust resource access extension. It is quite slow so should not be enabled by default. Only works for 1 level 2D color textures and buffers. Makes several flaky robust resource initialization tests consistently fail. Controlled via an angle::Feature in FeaturesVk. It works by initializing memory to an abitrary non-zero value: - if newly allocated memory is mappable, we map it in init and set it - if a buffer or texture can be a transfer destination, we use a staging resource - otherwise we don't attempt to initialize the resource.

Shahbaz Youssefi 6b275406 2020-01-09T11:14:47 Vulkan: Workaround vertex attributes vs stride issue on AMD Under robustBufferAccess, Vulkan states that: Vertex input attributes are considered out of bounds if the offset of the attribute in the bound vertex buffer range plus the size of the attribute is greater than either: - vertexBufferRangeSize, if bindingStride == 0; or - (vertexBufferRangeSize - (vertexBufferRangeSize % bindingStride)) The latter implies that if the buffer size is not a multiple of the vertex attribute stride, what lies beyond the last multiple of stride is considered out of bounds. It also says: Out-of-bounds buffer loads will return any of the following values: - Values from anywhere within the memory range(s) bound to the buffer (possibly including bytes of memory past the end of the buffer, up to the end of the bound range). - Zero values, or (0,0,0,x) vectors for vector reads where x is a valid value represented in the type of the vector components and may be any of ... The first bullet point indicates that the driver is allowed to load the attribute values from the buffer if its range still lies within the buffer size. Take the following example: - Buffer size = 12 - Attribute stride = 8 - Attribute offset = 0 - Attribute size = 4 Basically the buffer is thus laid out as follows: attr stride _________/\_________ / \ +----------+----------+----------+ | vertex 0 | padding | vertex 1 | +----------+----------+----------+ \___ ____/ V attr size In the above example, the attribute for vertex 1 is considered out of bounds, but the driver is allowed to either read it correctly, or return (0, 0, 0, 1) for it. Most drivers implement the former, while AMD implements the latter. This change introduces a workaround for AMD where GL_MAX_VERTEX_ATTRIB_STRIDE is limited to 2048 (the common value for it according to gpuinfo.org) and conservatively rounds up every buffer allocation to that size. While technically, this workaround should be applied on any device with the robustBufferAccess feature enabled, it is currently limited to AMD to avoid the inefficiency. A possible future revision of Vulkan may relax the above restrictions.

Kenneth Russell 7a37d3ac 2020-01-05T13:52:03 Work around Intel driver bug with CopyTex{Sub}Image2D/DeleteTextures. Dependencies seem to be incorrectly tracked in some Intel OpenGL drivers (on macOS specifically), causing crashes in glDeleteTextures if a GL command buffer is being constructed where those textures are destinations of CopyTexImage2D/CopyTexSubImage2D. Work around this bug by flushing before texture deletion if CopyTex{Sub}Image have been called recently. The tracking is only done on a per-context rather than a per-device basis, but seems sufficient to work around the problem as identified. Tested both with new ANGLE test on affected hardware, and in WebKit's ANGLE backend for WebGL. Works around the crash reported in https://bugs.webkit.org/show_bug.cgi?id=205707 .

Work around this by converting to DXT3 RGBA, adding an extra block of 1.0 alpha pixels for each color block. Mac Intel OpenGL requires additional workarounds to always sample 1.0 alpha.

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.

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.

Jonah Ryan-Davis 0716ce0a 2019-07-22T15:20:47 Re-add case to blitframebuffer workaround where src is outside of bounds. On Mac, blitFramebuffer calls fail if the source region is not enclosed by the framebuffer. In this case, we must naively clip the source region and adjust the dest region accordingly. This is slightly different behavior and may cause issues with scaling so we use a separate workaround. Also, Windows NVIDIA has a driver bug that affects Vulkan device creation after blitting large textures, so it should be included in the original workaround. This CL cleans up the workaround to use more helpers from ANGLE and to generally improve readability.

Shahbaz Youssefi 611bbaab 2018-12-06T01:59:53 Vulkan: Convert vertex attributes in compute In this commit, VertexArrayVk::convertVertexBuffer() is renamed to VertexArrayVk::convertVertexBufferCpu() to explicitly show it does a CPU readback. A new VertexArrayVk::convertVertexBuffer() function is added that has the same functionality in gpu (with some assumptions, where the CPU fallback is used should those assumptions fail). Currently, the only requirement is that buffer offset/stride are divided by the component size. ConvertVertex.comp is the shader responsible for this conversion, and it implements the functionality in renderer/copyvertex.inc, minus a few functions that are not used in the Vulkan backend.

This change unifies ANGLE EVENT* macro system so that at the base level in LoggingAnnotator class, systrace markers will be added by default. Modify the base DebugLogger to use char* by default and move any conversions to wchar_t to the Windows specializations where wchar is used. This limits type conversions to only where they're needed. This change also includes some new TRACE_EVENT() calls in the VK backend which will result in systrace markers for those calls on the Android platform.

Work around this by starting constant register allocations from 1. This should make sure that the bug doesn't trigger if the ordering of uniforms is changed on the D3D backend. The repro case seems to require some specific driver state to be set that's used inside Chromium. Because of this we have not been able to develop a standalone test case so far. The maximum number of available uniform slots is reduced accordingly. This should not take them below required minimums in the spec.

JiangYizhou 38d92b59 2017-09-13T13:47:52 Workaround Intel driver bug on D3D when renderering with no render target When rendering with no render target on D3D, two bugs lead to incorrect behavior on Intel drivers < 4815. The rendering samples always pass neglecting discard statement in pixel shader. Two bugs are listed bellow, 1. When a framebuffer has no attachments, the pixel shader will be recompiled to drop 'SV_TARGET'. On Intel drivers, when using a pixel shader with no 'SV_TARGET' in a draw, pixels are always generated even if they should be discard by 'discard' statements. 2. When a framebuffer has no attachments, ID3D11BlendState.RenderTarget [].RenderTargetWriteMask were set to 0 in angle. If RenderTargetWriteMask is 0 and rendertarget is not set, then rendering samples also pass neglecting discard statement in pixel shader on Intel. So we add a dummy texture as render target to workaround this issue.
