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 config VCHIQ_CDEV 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'. endif source "drivers/staging/vc04_services/bcm2835-audio/Kconfig" source "drivers/staging/vc04_services/bcm2835-camera/Kconfig" source "drivers/staging/vc04_services/vchiq-mmal/Kconfig" endif |
