# VkRenderingFlagBits(3) Manual Page

## Name

VkRenderingFlagBits - Bitmask specifying additional properties of a dynamic render pass instance

Loading… please wait.

## 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_EXT_legacy_dithering with (VK_KHR_dynamic_rendering or VK_VERSION_1_3) and (VK_KHR_maintenance5 or VK_VERSION_1_4)
        VK_RENDERING_ENABLE_LEGACY_DITHERING_BIT_EXT = 0x00000008,
      // Provided by VK_KHR_maintenance7
        VK_RENDERING_CONTENTS_INLINE_BIT_KHR = 0x00000010,
      // Provided by VK_VALVE_fragment_density_map_layered
        VK_RENDERING_PER_LAYER_FRAGMENT_DENSITY_BIT_VALVE = 0x00000020,
      // Provided by VK_KHR_dynamic_rendering
        VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT_KHR = VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT,
      // Provided by VK_KHR_dynamic_rendering
        VK_RENDERING_SUSPENDING_BIT_KHR = VK_RENDERING_SUSPENDING_BIT,
      // Provided by VK_KHR_dynamic_rendering
        VK_RENDERING_RESUMING_BIT_KHR = VK_RENDERING_RESUMING_BIT,
      // Provided by VK_EXT_nested_command_buffer
        VK_RENDERING_CONTENTS_INLINE_BIT_EXT = VK_RENDERING_CONTENTS_INLINE_BIT_KHR,
    } 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. If the `nestedCommandBuffer` feature is enabled, the draw calls can come from both inline and vkCmdExecuteCommands.

- `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.

- `VK_RENDERING_CONTENTS_INLINE_BIT_KHR` specifies that draw calls for the render pass instance can be recorded inline within the current command buffer. This can be combined with the `VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT` bit to allow draw calls to be recorded both inline and in secondary command buffers.

- `VK_RENDERING_PER_LAYER_FRAGMENT_DENSITY_BIT_VALVE` specifies that the render pass can be used with layered fragment density maps.

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.
