The SPIR-V extension allows shader modules to use -- invocation-private pointers into uniform and\/or storage buffers, where -- the pointer values can be dynamic and non-uniform. -- -- The @SPV_KHR_variable_pointers@ extension introduces two capabilities. -- The first, @VariablePointersStorageBuffer@, /must/ be supported by all -- implementations of this extension. The second, @VariablePointers@, is -- optional. -- -- == Promotion to Vulkan 1.1 -- -- All functionality in this extension is included in core Vulkan 1.1, with -- the KHR suffix omitted, however support for the -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#features-variablePointersStorageBuffer variablePointersStorageBuffer> -- feature is made optional. The original type, enum and command names are -- still available as aliases of the core functionality. -- -- == New Structures -- -- - Extending -- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2', -- 'Vulkan.Core10.Device.DeviceCreateInfo': -- -- - 'PhysicalDeviceVariablePointerFeaturesKHR' -- -- - 'PhysicalDeviceVariablePointersFeaturesKHR' -- -- == New Enum Constants -- -- - 'KHR_VARIABLE_POINTERS_EXTENSION_NAME' -- -- - 'KHR_VARIABLE_POINTERS_SPEC_VERSION' -- -- - Extending 'Vulkan.Core10.Enums.StructureType.StructureType': -- -- - 'STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES_KHR' -- -- - 'STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES_KHR' -- -- == New SPIR-V Capabilities -- -- - <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#spirvenv-capabilities-table-VariablePointers VariablePointers> -- -- - <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#spirvenv-capabilities-table-VariablePointersStorageBuffer VariablePointersStorageBuffer> -- -- == Issues -- -- 1) Do we need an optional property for the SPIR-V -- @VariablePointersStorageBuffer@ capability or should it be mandatory -- when this extension is advertised? -- -- __RESOLVED__: Add it as a distinct feature, but make support mandatory. -- Adding it as a feature makes the extension easier to include in a future -- core API version. In the extension, the feature is mandatory, so that -- presence of the extension guarantees some functionality. When included -- in a core API version, the feature would be optional. -- -- 2) Can support for these capabilities vary between shader stages? -- -- __RESOLVED__: No, if the capability is supported in any stage it must be -- supported in all stages. -- -- 3) Should the capabilities be features or limits? -- -- __RESOLVED__: Features, primarily for consistency with other similar -- extensions. -- -- == Version History -- -- - Revision 1, 2017-03-14 (Jesse Hall and John Kessenich) -- -- - Internal revisions -- -- == See Also -- -- 'PhysicalDeviceVariablePointerFeaturesKHR', -- 'PhysicalDeviceVariablePointersFeaturesKHR' -- -- == Document Notes -- -- For more information, see the -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_KHR_variable_pointers Vulkan Specification> -- -- This page is a generated document.
