Any device accesses to device coherent memory are automatically -- made visible to any other device access. Device uncached memory -- indicates to applications that caches are disabled for a particular -- memory type, which guarantees device coherence. -- -- Device coherent and uncached memory are expected to have lower -- performance for general access than non-device coherent memory, but can -- be useful in certain scenarios; particularly so for debugging. -- -- == New Structures -- -- - Extending -- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2', -- 'Vulkan.Core10.Device.DeviceCreateInfo': -- -- - 'PhysicalDeviceCoherentMemoryFeaturesAMD' -- -- == New Enum Constants -- -- - 'AMD_DEVICE_COHERENT_MEMORY_EXTENSION_NAME' -- -- - 'AMD_DEVICE_COHERENT_MEMORY_SPEC_VERSION' -- -- - Extending -- 'Vulkan.Core10.Enums.MemoryPropertyFlagBits.MemoryPropertyFlagBits': -- -- - 'Vulkan.Core10.Enums.MemoryPropertyFlagBits.MEMORY_PROPERTY_DEVICE_COHERENT_BIT_AMD' -- -- - 'Vulkan.Core10.Enums.MemoryPropertyFlagBits.MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD' -- -- - Extending 'Vulkan.Core10.Enums.StructureType.StructureType': -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_COHERENT_MEMORY_FEATURES_AMD' -- -- == Version History -- -- - Revision 1, 2019-02-04 (Tobias Hector) -- -- - Initial revision -- -- == See Also -- -- 'PhysicalDeviceCoherentMemoryFeaturesAMD' -- -- == Document Notes -- -- For more information, see the -- -- -- This page is a generated document.
