C Specification

Bits which can be set in VkRenderingInfo::flags describing additional properties of the render pass are:

// Provided by VK_VERSION_1_3
typedef enum VkRenderingFlagBits {
    VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT = 0x00000001,
    VK_RENDERING_SUSPENDING_BIT = 0x00000002,
    VK_RENDERING_RESUMING_BIT = 0x00000004,
  // Provided by VK_VERSION_1_3 with VK_EXT_legacy_dithering, VK_KHR_dynamic_rendering with VK_EXT_legacy_dithering
    VK_RENDERING_ENABLE_LEGACY_DITHERING_BIT_EXT = 0x00000008,
    VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT_KHR = VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT,
    VK_RENDERING_SUSPENDING_BIT_KHR = VK_RENDERING_SUSPENDING_BIT,
    VK_RENDERING_RESUMING_BIT_KHR = VK_RENDERING_RESUMING_BIT,
} VkRenderingFlagBits;

or the equivalent

// Provided by VK_KHR_dynamic_rendering
typedef VkRenderingFlagBits VkRenderingFlagBitsKHR;

Description

  • VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT specifies that draw calls for the render pass instance will be recorded in secondary command buffers.

  • VK_RENDERING_RESUMING_BIT specifies that the render pass instance is resuming an earlier suspended render pass instance.

  • VK_RENDERING_SUSPENDING_BIT specifies that the render pass instance will be suspended.

  • VK_RENDERING_ENABLE_LEGACY_DITHERING_BIT_EXT specifies that Legacy Dithering is enabled for the render pass instance.

The contents of pRenderingInfo must match between suspended render pass instances and the render pass instances that resume them, other than the presence or absence of the VK_RENDERING_RESUMING_BIT, VK_RENDERING_SUSPENDING_BIT, and VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT flags. No action or synchronization commands, or other render pass instances, are allowed between suspending and resuming render pass instances.
