| 0x0302 | `nx_drv_create_command_buffer` | This has to be called from a driver. Registers _addr_ as command queue buffer with the length _len_, which has to be greater or equal 16384. If _addr_ is NULL or not aligned to 32 bytes or _len_ is less than 16384, the kernel will map a command queue buffer into the drivers address space, which is of length _len_ but at least 16384. The address to the registered buffer will be returned. | addr | len | | | addr | N/A | | 0x0302 | `nx_drv_init` | This has to be called from a driver. This can only be called once per driver. Initializes the calling driver process with the configuration _conf_. The format of the conf struct can be found below. | *conf | | | | status | N/A |
