VkPhysicalDeviceShader64BitIndexingFeaturesEXT - Structure describing 64-bit indexing features that can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceShader64BitIndexingFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceShader64BitIndexingFeaturesEXT, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.

VkShaderCreateFlagBitsEXT - Bitmask controlling how a shader object is created

Description

• SHADER_CREATE_LINK_STAGE_BIT_EXT specifies that a shader is linked to all other shaders created in the same createShadersEXT call whose ShaderCreateInfoEXT structures' flags include SHADER_CREATE_LINK_STAGE_BIT_EXT.

• SHADER_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT_EXT specifies that the SubgroupSize may vary in a task, mesh, or compute shader.

• SHADER_CREATE_REQUIRE_FULL_SUBGROUPS_BIT_EXT specifies that the subgroup sizes must be launched with all invocations active in a task, mesh, or compute shader.

• SHADER_CREATE_NO_TASK_SHADER_BIT_EXT specifies that a mesh shader must only be used without a task shader. Otherwise, the mesh shader must only be used with a task shader.

• SHADER_CREATE_DISPATCH_BASE_BIT_EXT specifies that a compute shader can be used with cmdDispatchBase with a non-zero base workgroup.

• SHADER_CREATE_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_EXT specifies that a fragment shader can be used with a fragment shading rate attachment.

• SHADER_CREATE_FRAGMENT_DENSITY_MAP_ATTACHMENT_BIT_EXT specifies that a fragment shader can be used with a fragment density map attachment.

• SHADER_CREATE_INDIRECT_BINDABLE_BIT_EXT specifies that the shader can be used in combination with https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#device-generated-commands.

• SHADER_CREATE_OPACITY_MICROMAP_DISALLOW_MIXED_SPECIAL_INDEX_BIT_EXT specifies that shader objects cannot be used with acceleration structures which are built with geometry that have an index buffer including both special indices and indices pointing to an associated micromap array. Geometry which has an index buffer using only special indices without an associated micromap array can be used with this flag.

• SHADER_CREATE_INDEPENDENT_SETS_BIT_KHR specifies that implementations must ensure that the properties and/or absence of a particular descriptor set do not influence any other descriptor sets for the shader. This allows shader objects to be created with a subset of the total descriptor sets.

• SHADER_CREATE_64_BIT_INDEXING_BIT_EXT specifies that the shader enables 64-bit indexing.

• SHADER_CREATE_DESCRIPTOR_HEAP_BIT_EXT specifies that the shader will use descriptor heap mappings instead of descriptor set layouts.
