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.
