| '''OpenGL extension AMD.pinned_memory |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.AMD.pinned_memory to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension defines an interface that allows improved control |
| of the physical memory used by the graphics device. |
| |
| It allows an existing page of system memory allocated by the application |
| to be used as memory directly accessible to the graphics processor. One |
| example application of this functionality would be to be able to avoid an |
| explicit synchronous copy with sub-system of the application; for instance |
| it is possible to directly draw from a system memory copy of a video |
| image. |
| |
| The official definition of this extension is available here: |
