  625. ----------------------
  626. * lazy_clear_resource_on_first_use:
  627. (https://crbug.com/dawn/145):
  628. Clears resource to zero on first usage. This initializes the resource so
  629. that no dirty bits from recycled memory is present in the new resource.
  630.  
  631. * use_temporary_buffer_in_texture_to_texture_copy:
  632. (https://crbug.com/dawn/42):
  633. Split texture-to-texture copy into two copies: copy from source texture
  634. into a temporary buffer, and copy from the temporary buffer into the
  635. destination texture when copying between compressed textures that don't
  636. have block-aligned sizes. This workaround is enabled by default on all
  637. Vulkan drivers to solve an issue in the Vulkan SPEC about the
  638. texture-to-texture copies with compressed formats. See #1005
  639. (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more
  640. details.
  641.  
  642. * vulkan_use_d32s8:
  643. (https://crbug.com/dawn/286):
  644. Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When
  645. available the backend will use D32S8 (toggle to on) but setting the toggle
  646. to off will make it use the D24S8 format when possible.
  647.  
  648. * vulkan_use_s8:
  649. (https://crbug.com/dawn/666):
  650. Vulkan has a pure stencil8 format but it is not universally available.
  651. When this toggle is on, the backend will use S8 for the stencil8 format,
  652. otherwise it will fallback to D32S8 or D24S8.
  653.  
  654. * disallow_spirv:
  655. (https://crbug.com/1214923):
  656. Disallow usage of SPIR-V completely so that only WGSL is used for shader
  657. modules. This is useful to prevent a Chromium renderer process from
  658. successfully sending SPIR-V code to be compiled in the GPU process.
  659.  
  660. * use_placeholder_fragment_in_vertex_only_pipeline:
  661. (https://crbug.com/dawn/136):
  662. Use a placeholder empty fragment shader in vertex only render pipeline.
  663. This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and
  664. serves as a workaround by default enabled on some Metal devices with Intel
  665. GPU to ensure the depth result is correct.
  666.  
  667. * timestamp_quantization:
  668. (https://crbug.com/dawn/1800):
  669. Enable timestamp queries quantization to reduce the precision of timers
  670. that can be created with timestamp queries.
  671.  
  672. * use_vulkan_zero_initialize_workgroup_memory_extension:
  673. (https://crbug.com/dawn/1302):
  674. Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan
  675. extension VK_KHR_zero_initialize_workgroup_memory is supported.
  676.

  678. -----------------------------------
