Description

This extension adds some more dynamic state to support applications that need to reduce the number of pipeline state objects they compile and bind.

New Commands

• vkCmdSetDepthBiasEnableEXT
• vkCmdSetLogicOpEXT
• vkCmdSetPatchControlPointsEXT
• vkCmdSetPrimitiveRestartEnableEXT
• vkCmdSetRasterizerDiscardEnableEXT

New Structures

• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDeviceExtendedDynamicState2FeaturesEXT

New Enum Constants

• VK_EXT_EXTENDED_DYNAMIC_STATE_2_EXTENSION_NAME
• VK_EXT_EXTENDED_DYNAMIC_STATE_2_SPEC_VERSION
• Extending VkDynamicState:
  • VK_DYNAMIC_STATE_DEPTH_BIAS_ENABLE_EXT
  • VK_DYNAMIC_STATE_LOGIC_OP_EXT
  • VK_DYNAMIC_STATE_PATCH_CONTROL_POINTS_EXT
  • VK_DYNAMIC_STATE_PRIMITIVE_RESTART_ENABLE_EXT
  • VK_DYNAMIC_STATE_RASTERIZER_DISCARD_ENABLE_EXT
• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTENDED_DYNAMIC_STATE_2_FEATURES_EXT

Promotion to Vulkan 1.3

This extension has been partially promoted. The dynamic state enumerants VK_DYNAMIC_STATE_DEPTH_BIAS_ENABLE_EXT, VK_DYNAMIC_STATE_PRIMITIVE_RESTART_ENABLE_EXT, and VK_DYNAMIC_STATE_RASTERIZER_DISCARD_ENABLE_EXT; and the corresponding commands in this extension are included in core Vulkan 1.3, with the EXT suffix omitted. The enumerants and commands for dynamic logic operation and patch control points are not promoted, nor is the feature structure. Extension interfaces that were promoted remain available as aliases of the core functionality.
