Description

These values all have the same meaning as the equivalently named values for VkPipelineStageFlags2.

  • VK_PIPELINE_STAGE_NONE specifies no stages of execution.

  • VK_PIPELINE_STAGE_DRAW_INDIRECT_BIT specifies the stage of the pipeline where VkDrawIndirect* / VkDispatchIndirect* / VkTraceRaysIndirect* data structures are consumed.

  • VK_PIPELINE_STAGE_VERTEX_INPUT_BIT specifies the stage of the pipeline where vertex and index buffers are consumed.

  • VK_PIPELINE_STAGE_VERTEX_SHADER_BIT specifies the vertex shader stage.

  • VK_PIPELINE_STAGE_TESSELLATION_CONTROL_SHADER_BIT specifies the tessellation control shader stage.

  • VK_PIPELINE_STAGE_TESSELLATION_EVALUATION_SHADER_BIT specifies the tessellation evaluation shader stage.

  • VK_PIPELINE_STAGE_GEOMETRY_SHADER_BIT specifies the geometry shader stage.

  • VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT specifies the fragment shader stage.

  • VK_PIPELINE_STAGE_EARLY_FRAGMENT_TESTS_BIT specifies the stage of the pipeline where early fragment tests (depth and stencil tests before fragment shading) are performed. This stage also includes render pass load operations for framebuffer attachments with a depth/stencil format.

  • VK_PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT specifies the stage of the pipeline where late fragment tests (depth and stencil tests after fragment shading) are performed. This stage also includes render pass store operations for framebuffer attachments with a depth/stencil format.

  • VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT specifies the stage of the pipeline after blending where the final color values are output from the pipeline. This stage includes blending, logic operations, render pass load and store operations for color attachments, render pass multisample resolve operations, and vkCmdClearAttachments.

  • VK_PIPELINE_STAGE_COMPUTE_SHADER_BIT specifies the execution of a compute shader.

  • VK_PIPELINE_STAGE_TRANSFER_BIT specifies the following commands:

  • VK_PIPELINE_STAGE_HOST_BIT specifies a pseudo-stage indicating execution on the host of reads/writes of device memory. This stage is not invoked by any commands recorded in a command buffer.

  • VK_PIPELINE_STAGE_ALL_GRAPHICS_BIT specifies the execution of all graphics pipeline stages, and is equivalent to the logical OR of:

    • VK_PIPELINE_STAGE_DRAW_INDIRECT_BIT

    • VK_PIPELINE_STAGE_VERTEX_INPUT_BIT

    • VK_PIPELINE_STAGE_VERTEX_SHADER_BIT

    • VK_PIPELINE_STAGE_TESSELLATION_CONTROL_SHADER_BIT

    • VK_PIPELINE_STAGE_TESSELLATION_EVALUATION_SHADER_BIT

    • VK_PIPELINE_STAGE_GEOMETRY_SHADER_BIT

    • VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT

    • VK_PIPELINE_STAGE_EARLY_FRAGMENT_TESTS_BIT

    • VK_PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT

    • VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT

    • VK_PIPELINE_STAGE_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_KHR

  • VK_PIPELINE_STAGE_ALL_COMMANDS_BIT specifies all operations performed by all commands supported on the queue it is used with.

  • VK_PIPELINE_STAGE_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_KHR specifies the stage of the pipeline where the fragment shading rate attachment is read to determine the fragment shading rate for portions of a rasterized primitive.

  • VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT is equivalent to VK_PIPELINE_STAGE_ALL_COMMANDS_BIT with VkAccessFlags set to 0 when specified in the second synchronization scope, but specifies no stage of execution when specified in the first scope.

  • VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT is equivalent to VK_PIPELINE_STAGE_ALL_COMMANDS_BIT with VkAccessFlags set to 0 when specified in the first synchronization scope, but specifies no stage of execution when specified in the second scope.
