| === 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. |
