C Specification
The VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
structure is
defined as:
// Provided by VK_EXT_subgroup_size_control
typedef struct VkPhysicalDeviceSubgroupSizeControlFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 subgroupSizeControl;
VkBool32 computeFullSubgroups;
} VkPhysicalDeviceSubgroupSizeControlFeaturesEXT;
Description
-
subgroupSizeControl
indicates whether the implementation supports controlling shader subgroup sizes via theVK_PIPELINE_SHADER_STAGE_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT_EXT
flag and the VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT structure. -
computeFullSubgroups
indicates whether the implementation supports requiring full subgroups in compute shaders via theVK_PIPELINE_SHADER_STAGE_CREATE_REQUIRE_FULL_SUBGROUPS_BIT_EXT
flag.
If the VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
structure is included in the pNext
chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
can also be used in the pNext
chain of
VkDeviceCreateInfo to selectively enable these features.
