C Specification
The VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR
structure is
defined as:
// Provided by VK_KHR_compute_shader_derivatives
typedef struct VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR {
VkStructureType sType;
void* pNext;
VkBool32 computeDerivativeGroupQuads;
VkBool32 computeDerivativeGroupLinear;
} VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR;
or the equivalent
// Provided by VK_NV_compute_shader_derivatives
typedef VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR VkPhysicalDeviceComputeShaderDerivativesFeaturesNV;
Members
This structure describes the following features:
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
computeDerivativeGroupQuads
indicates that the implementation supports theComputeDerivativeGroupQuadsKHR
SPIR-V capability. -
computeDerivativeGroupLinear
indicates that the implementation supports theComputeDerivativeGroupLinearKHR
SPIR-V capability.
Description
See Quad shader scope for more information.
If the VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR
. 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.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR
., it must add an instance of the structure,
with the desired feature members set to VK_TRUE
, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
