## 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_EXT_custom_resolve with VK_KHR_dynamic_rendering or VK_VERSION_1_3
        VK_RENDERING_FRAGMENT_REGION_BIT_EXT = 0x00000040,
      // Provided by VK_EXT_custom_resolve with VK_KHR_dynamic_rendering or VK_VERSION_1_3
        VK_RENDERING_CUSTOM_RESOLVE_BIT_EXT = 0x00000080,
      // Provided by VK_KHR_maintenance10 with (VK_VERSION_1_4 or VK_KHR_dynamic_rendering_local_read) and (VK_VERSION_1_3 or VK_KHR_dynamic_rendering)
        VK_RENDERING_LOCAL_READ_CONCURRENT_ACCESS_CONTROL_BIT_KHR = 0x00000100,
      // 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;

    // Provided by VK_KHR_dynamic_rendering
    // Equivalent to VkRenderingFlagBits
    typedef VkRenderingFlagBits VkRenderingFlagBitsKHR;

## Description

- VK_RENDERING_CONTENTS_SECONDARY_COMMAND_BUFFERS_BIT specifies that contents for the render pass instance will be recorded in secondary command buffers, and vkCmdExecuteCommands is the only valid command in the command buffer until vkCmdEndRendering2KHR or vkCmdEndRendering. If the `nestedCommandBuffer` feature is enabled, the contents 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 contents 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 contents 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.

- VK_RENDERING_LOCAL_READ_CONCURRENT_ACCESS_CONTROL_BIT_KHR specifies that VK_RENDERING_ATTACHMENT_INPUT_ATTACHMENT_FEEDBACK_BIT_KHR will always be specified for any attachment which invokes the behavior described by that flag.

- VK_RENDERING_FRAGMENT_REGION_BIT_EXT specifies that the render pass can access samples which are not covered in its `SampleMask`.

- VK_RENDERING_CUSTOM_RESOLVE_BIT_EXT specifies that the render pass contains a custom resolve. When this bit is set, vkCmdBeginCustomResolveEXT can be called.

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.
