C Specification

A subpass shading pipeline’s workgroup size is a 2D vector with number of power-of-two in width and height. The maximum number of width and height is implementation-dependent, and may vary for different formats and sample counts of attachments in a render pass.

To query the maximum workgroup size, call:

// Provided by VK_HUAWEI_subpass_shading
VkResult vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI(
    VkDevice                                    device,
    VkRenderPass                                renderpass,
    VkExtent2D*                                 pMaxWorkgroupSize);

Parameters

  • device is a handle to a local device object that was used to create the given render pass.

  • renderPass is a handle to a render pass object describing the environment in which the pipeline will be used. The pipeline must only be used with a render pass instance compatible with the one provided. See Render Pass Compatibility for more information.

  • pMaxWorkgroupSize is a pointer to a VkExtent2D structure.

Description

Valid Usage (Implicit)

  • VUID-vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI-renderpass-parameter
    renderpass must be a valid VkRenderPass handle

  • VUID-vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI-pMaxWorkgroupSize-parameter
    pMaxWorkgroupSize must be a valid pointer to VkExtent2D structures

  • VUID-vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI-renderpass-parent
    renderpass must have been created, allocated, or retrieved from device

Return Codes

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_SURFACE_LOST_KHR
