vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI

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:

VkResult vkGetDeviceSubpassShadingMaxWorkgroupSizeHUAWEI(
    VkDevice device,
    VkRenderPass renderpass,
    VkExtent2D* pMaxWorkgroupSize);

• 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.
