C Specification

Bits which can be set in the VkPipelineDepthStencilStateCreateInfo::flags parameter are:

// Provided by VK_EXT_rasterization_order_attachment_access
typedef enum VkPipelineDepthStencilStateCreateFlagBits {
  // Provided by VK_EXT_rasterization_order_attachment_access
    VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_EXT = 0x00000001,
  // Provided by VK_EXT_rasterization_order_attachment_access
    VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_EXT = 0x00000002,
  // Provided by VK_ARM_rasterization_order_attachment_access
    VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_ARM = VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_EXT,
  // Provided by VK_ARM_rasterization_order_attachment_access
    VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_ARM = VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_EXT,
} VkPipelineDepthStencilStateCreateFlagBits;

Description

  • VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_EXT indicates that access to the depth aspects of depth/stencil and input attachments will have implicit framebuffer-local memory dependencies.

  • VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_EXT indicates that access to the stencil aspects of depth/stencil and input attachments will have implicit framebuffer-local memory dependencies.

When VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_EXT is included in a pipeline, it forms a framebuffer-local memory dependency for each fragment generated by draw commands for that pipeline with the following scopes:

  • The first synchronization scope includes VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT and VK_PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT pipeline stages executed by all previous fragments (as defined by primitive order) in the corresponding framebuffer regions including those generated by the same draw command.

  • The second synchronization scope includes VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT stage executed by the generated fragment.

  • The first access scope includes all writes to the depth aspect of depth/stencil attachments.

  • The second access scope includes all reads from the depth aspect of input attachments.

When VK_PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_EXT is included in a pipeline, it forms a framebuffer-local memory dependency for each fragment generated by draw commands for that pipeline with the following scopes:

  • The first synchronization scope includes VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT VK_PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT pipeline stages executed by all previous fragments (as defined by primitive order) in the corresponding framebuffer regions including those generated by the same draw command.

  • The second synchronization scope includes VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT and VK_PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT pipeline stages executed by the generated fragment.

  • The first access scope includes all writes to the stencil aspect of depth/stencil attachments.

  • The second access scope includes all reads from the stencil aspect of input attachments.
