Initialize the RSX context and the RSX memory manager.
The user must provide a 1 MB-aligned IO buffer allocated in main memory, which size is a multiple of 1 megabyte.
This function initializes a heap structure in RSX memory space, allowing dynamic memory allocation using rsxMalloc, rsxMemalign and rsxFree.
- Parameters
-
| context | Pointer to receive the address of the default command buffer |
| cmdSize | The command buffer size. |
| ioSize | The allocated IO buffer size. |
| ioAddress | Pointer to an allocated buffer of ioSize bytes. |
- Returns
- zero if no error occured, nonzero otherwise.
