vkCmdSetCoverageReductionModeNV(3)

C Specification

To dynamically set the coverageReductionMode state, call:

// Provided by VK_EXT_extended_dynamic_state3 with VK_NV_coverage_reduction_mode, VK_EXT_shader_object with VK_NV_coverage_reduction_mode
void vkCmdSetCoverageReductionModeNV(
    VkCommandBuffer                             commandBuffer,
    VkCoverageReductionModeNV                   coverageReductionMode);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
coverageReductionMode specifies the coverageReductionMode state.

Description

This command sets the coverageReductionMode state for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_COVERAGE_REDUCTION_MODE_NV set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineCoverageReductionStateCreateInfoNV::coverageReductionMode value used to create the currently active pipeline.

Valid Usage

Either the extendedDynamicState3CoverageReductionMode feature or the shaderObject feature or both must be enabled

Valid Usage (Implicit)

VUID-vkCmdSetCoverageReductionModeNV-commandBuffer-parameter

VUID-vkCmdSetCoverageReductionModeNV-coverageReductionMode-parameter
coverageReductionMode must be a valid VkCoverageReductionModeNV value
VUID-vkCmdSetCoverageReductionModeNV-commandBuffer-recording
commandBuffer must be in the recording state
VUID-vkCmdSetCoverageReductionModeNV-commandBuffer-cmdpool
The VkCommandPool that commandBuffer was allocated from must support graphics operations
VUID-vkCmdSetCoverageReductionModeNV-videocoding

Host Synchronization

Host access to commandBuffer must be externally synchronized
Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
