| help |
| Broadcom BCM2835 and similar SoCs have a VPU called VideoCore. |
| This config enables the VCHIQ driver, which implements a |
| messaging interface between the kernel and the firmware running |
| on VideoCore. Other drivers use this interface to communicate to |
| the VPU. More specifically, the VCHIQ driver is used by |
| audio/video and camera drivers as well as for implementing MMAL |
| API, which is in turn used by several multimedia services on the |
| BCM2835 family of SoCs. |
| |
| Defaults to Y when the Broadcom Videocore services are included |
| in the build, N otherwise. |

| bool "VCHIQ Character Driver" |
| help |
| Enable the creation of VCHIQ character driver. The cdev exposes |
| ioctls used by userspace libraries and testing tools to interact |
| with VideoCore, via the VCHIQ core driver (Check BCM2835_VCHIQ |
| for more info). |
| |
| This can be set to 'N' if the VideoCore communication is not |
| needed by userspace but only by other kernel modules |
| (like bcm2835-audio). |
| |
| If not sure, set this to 'Y'. |
