Open the GPU.
Call lv1_gpu_close to close the GPU.
status = lv1_gpu_open( /*IN*/ p1 );
| Inputs | |
|---|---|
| Register | Description |
| R3 | p1 - Unknown, Kernel only ever passes 0, though other randomly chosen values seem to succeed. |
| Outputs | |
| Register | Description |
| R3 | status: 0 = LV1_SUCCESS, -6 = LV1_NO_ENTRY |
Notes:
When called from Kernel module init function, if GPU is already open, subsequent calls to lv1_gpu_open return LV1_NO_ENTRY (-6). Closing the GPU and re-opening succeeds.
