C Specification
The VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
structure is
defined as:
typedef struct VkPhysicalDeviceSubgroupSizeControlFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 subgroupSizeControl;
VkBool32 computeFullSubgroups;
} VkPhysicalDeviceSubgroupSizeControlFeaturesEXT;
Members
The members of the VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
structure describe the following features:
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 VkPhysicalDeviceFeatures2, it is
filled with values indicating whether the feature is supported.
VkPhysicalDeviceSubgroupSizeControlFeaturesEXT
can also be used in
the pNext
chain of VkDeviceCreateInfo to enable the feature.
