- 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.
- if BCM2835_VCHIQ

- 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'.
