Description

This extension adds the device coherent and device uncached memory types. 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.

VkPhysicalDeviceCoherentMemoryFeaturesAMD - Structure describing whether device coherent memory can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceCoherentMemoryFeaturesAMD 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. PhysicalDeviceCoherentMemoryFeaturesAMD can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
