This is useful to prevent a Chromium renderer process from successfully sending SPIR-V code to be compiled in the GPU process. * use_placeholder_fragment_in_vertex_only_pipeline: (https://crbug.com/dawn/136): Use a placeholder empty fragment shader in vertex only render pipeline.

Scale the depth bias value by multiple 0.5 on certain backends to achieve conformant result. * enable_integer_range_analysis_in_robustness: (https://crbug.com/348701956): Compute the range of the index with Integer Range Analysis in the robustness transform and skip doing index clamping when the out of bound access cannot happen. * blob_cache_hash_validation: (https://crbug.com/429938352): Enable hash validation when loading/storing from/to the blob cache * decompose_uniform_buffers: (https://crbug.com/448452698): Decompose uniform buffers into arrays of vec4 on backends for Vulkan and OpenGL.

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_spirv: (https://crbug.com/1214923): Disallow usage of SPIR-V completely so that only WGSL is used for shader modules.

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_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. * vulkan_use_demote_to_helper_invocation_extension: (https://crbug.com/42250787): Sets the use of the vulkan demote to helper extension * use_placeholder_fragment_in_vertex_only_pipeline: (https://crbug.com/dawn/136): Use a placeholder empty fragment shader in vertex only render pipeline. This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and serves as a workaround by default enabled on some Metal devices with Intel GPU to ensure the depth result is correct. * timestamp_quantization: (https://crbug.com/dawn/1800): Enable timestamp queries quantization to reduce the precision of timers that can be created with timestamp queries. * 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. * vulkan_use_image_robust_access_2: (https://crbug.com/tint/1890): Disable Tint robustness transform on textures when VK_EXT_robustness2 is supported and robustImageAccess2 == VK_TRUE. * vulkan_use_buffer_robust_access_2: (https://crbug.com/tint/1890): Disable index clamping on the runtime-sized arrays on buffers in Tint robustness transform when VK_EXT_robustness2 is supported and robustBufferAccess2 == VK_TRUE. * use_vulkan_memory_model: (https://crbug.com/392606604): Use the Vulkan Memory Model if available. * enable_integer_range_analysis_in_robustness: (https://crbug.com/348701956): Compute the range of the index with Integer Range Analysis in the robustness transform and skip doing index clamping when the out of bound access cannot happen. * use_spirv_1_4: (https://crbug.com/422421915): Use SPIR-V 1.4 if available * blob_cache_hash_validation: (https://crbug.com/429938352): Enable hash validation when loading/storing from/to the blob cache * decompose_uniform_buffers: (https://crbug.com/448452698): Decompose uniform buffers into arrays of vec4 on backends for Vulkan and OpenGL. * vulkan_use_dynamic_rendering: (https://crbug.com/dawn/463893794): Makes use of VK_KHR_dynamic_rendering to implement WebGPU RenderPass. * enable_spirv_validation: (https://crbug.com/473526415): Enable validation of SPIR-V generated by Tint. * vulkan_use_create_render_pass_2: (https://crbug.com/chromium/463893793): Makes use of VK_KHR_create_renderpass2 when creating VkRenderPass objects. Ignored when vulkan_use_dynamic_rendering is enabled. * vulkan_use_rasterization_order_attachment_access: (https://crbug.com/42241389): Use VK_EXT_rasterization_order_attachment_access when it is available. * use_spirv_reconvergence_mode: (https://crbug.com/379673383): Use SPIR-V reconvergence execution mode if supported by the device. * vulkan_use_cooperative_matrix_robust_access: (https://crbug.com/548005877): Disable clamping of subgroupMatrixLoad/Store on storage buffers if cooperativeMatrixRobustBufferAccess == VK_TRUE * wait_is_thread_safe: (https://crbug.com/412761228): WaitFor* functions are thread-safe and can be called without the device-lock if implicit synchronization is enabled. [WebGPU Required 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. * timestamp_quantization: (https://crbug.com/dawn/1800): Enable timestamp queries quantization to reduce the precision of timers that can be created with timestamp queries.
