DAWN Info Metal backend - Apple M1 [Default Toggle Names] always_resolve_into_zero_level_and_layer: https://crbug.com/dawn/56: When the resolve target is a texture view that is created on the non-zero level or layer of a texture, we first resolve into a temporarily 2D texture with only one mipmap level and one array layer, and copy the result of MSAA resolve into the true resolve target. This workaround is enabled by default on the Metal drivers that have bugs when setting non-zero resolveLevel or resolveSlice. lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource. metal_enable_vertex_pulling: https://crbug.com/dawn/480: Uses vertex pulling to protect out-of-bounds reads on Metal disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet. [WebGPU Forced Toggles - enabled] disallow_spirv: https://crbug.com/1214923: Disallow usage of SPIR-V completely so that only WGSL is used for shader modules. This is useful to prevent a Chromium renderer process from successfully sending SPIR-V code to be compiled in the GPU process. [Supported Features] texture-compression-bc texture-compression-etc2 texture-compression-astc depth-clip-control depth32float-stencil8 indirect-first-instance dawn-internal-usages multiplanar-formats dawn-native Vulkan backend - SwiftShader Device (LLVM 10.0.0) [Default Toggle Names] lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource. use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details. vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible. vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8. disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet. use_vulkan_zero_initialize_workgroup_memory_extension: https://crbug.com/dawn/1302: Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan extension VK_KHR_zero_initialize_workgroup_memory is supported.

forceNonCSBaseMipmapGeneration (Metal features): Disabled: isIntel() Turn this feature on to disallow Compute Shader based mipmap generation. Compute Shader based mipmap generation might cause GPU hang on some older iOS devices. hasBaseVertexInstancedDraw (Metal features): Enabled: isOSX || isCatalyst || supportsAppleGPUFamily(3) The renderer supports base vertex instanced draw hasCheapRenderPass (Metal features): Disabled: (isOSX || isCatalyst) && !isARM The renderer can cheaply break a render pass. hasDepthAutoResolve (Metal features): Enabled: supportsEitherGPUFamily(3, 2) The renderer supports MSAA depth auto resolve at the end of render pass hasEvents (Metal features): Enabled: isMetal2_1 && !isNVIDIA() The renderer supports MTL(Shared)Event hasExplicitMemBarrier (Metal features): Disabled: isMetal2_1 && (isOSX || isCatalyst) && !isARM The renderer supports explicit memory barrier hasNonUniformDispatch (Metal features): Enabled: isOSX || isCatalyst || supportsAppleGPUFamily(4) The renderer supports non uniform compute shader dispatch's group size hasShaderStencilOutput (Metal features): Enabled: isMetal2_1 && !isIntel() && !isNVIDIA() The renderer supports stencil output from fragment shader hasStencilAutoResolve (Metal features): Enabled: supportsEitherGPUFamily(5, 2) The renderer supports MSAA stencil auto resolve at the end of render pass hasTextureSwizzle (Metal features): Enabled: isMetal2_2 && supportsEitherGPUFamily(3, 2) && !isSimulator The renderer supports texture swizzle intelDisableFastMath (Metal workarounds): Disabled: isIntel() && GetMacOSVersion() < OSVersion(12, 0, 0) Disable fast math in atan and invariance cases when running below macOS 12.0 intelExplicitBoolCastWorkaround (Metal workarounds): Disabled: isIntel() && GetMacOSVersion() < OSVersion(11, 0, 0) Insert explicit casts for float/double/unsigned/signed int on macOS 10.15 with Intel driver limitMaxColorTargetBitsForTesting (Metal features) anglebug:7280: Disabled Metal iOS has a limit on the number of color target bits per pixel. limitMaxDrawBuffersForTesting (Metal features) anglebug:7280: Disabled Used to check the backend works when the device's advertized limit is less than the code's limit multisampleColorFormatShaderReadWorkaround (Metal workarounds) anglebug:7049: Disabled: isAMD() Add shaderRead usage to some multisampled texture formats rewriteRowMajorMatrices (Metal features): Enabled: true Rewrite row major matrices in shaders as column major. DAWN Info Metal backend - Apple M1 [Default Toggle Names] always_resolve_into_zero_level_and_layer: https://crbug.com/dawn/56: When the resolve target is a texture view that is created on the non-zero level or layer of a texture, we first resolve into a temporarily 2D texture with only one mipmap level and one array layer, and copy the result of MSAA resolve into the true resolve target. This workaround is enabled by default on the Metal drivers that have bugs when setting non-zero resolveLevel or resolveSlice. lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource. metal_enable_vertex_pulling: https://crbug.com/dawn/480: Uses vertex pulling to protect out-of-bounds reads on Metal disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet. [WebGPU Forced Toggles - enabled] disallow_spirv: https://crbug.com/1214923: Disallow usage of SPIR-V completely so that only WGSL is used for shader modules. This is useful to prevent a Chromium renderer process from successfully sending SPIR-V code to be compiled in the GPU process.

This initializes the resource so that no dirty bits from recycled memory is present in the new resource. use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details. vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible. vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8. disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet. use_vulkan_zero_initialize_workgroup_memory_extension: https://crbug.com/dawn/1302: Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan extension VK_KHR_zero_initialize_workgroup_memory is supported.
