VkPhysicalDeviceShaderFmaFeaturesKHR

The VkPhysicalDeviceShaderFmaFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceShaderFmaFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 shaderFmaFloat16;
    VkBool32 shaderFmaFloat32;
    VkBool32 shaderFmaFloat64;
} VkPhysicalDeviceShaderFmaFeaturesKHR;

pub struct PhysicalDeviceShaderFmaFeaturesKHR {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    shader_fma_float16: vk::Bool32,
    shader_fma_float32: vk::Bool32,
    shader_fma_float64: vk::Bool32,
}

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• shaderFmaFloat16 indicates whether the implementation supports OpFmaKHR for Float16 types in shaders.
• shaderFmaFloat32 indicates whether the implementation supports OpFmaKHR for Float32 types in shaders.
• shaderFmaFloat64 indicates whether the implementation supports OpFmaKHR for Float64 types in shaders.

If the VkPhysicalDeviceShaderFmaFeaturesKHR 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 VkPhysicalDeviceShaderFmaFeaturesKHR, 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.
