15 tristate "BCM2835 VCHIQ"
19 Broadcom BCM2835 and similar SoCs have a VPU called VideoCore.
20 This config enables the VCHIQ driver, which implements a
21 messaging interface between the kernel and the firmware running
22 on VideoCore. Other drivers use this interface to communicate to
23 the VPU. More specifically, the VCHIQ driver is used by
24 audio/video and camera drivers as well as for implementing MMAL
25 API, which is in turn used by several multimedia services on the
26 BCM2835 family of SoCs.
28 Defaults to Y when the Broadcom Videocore services are included
29 in the build, N otherwise.
34 bool "VCHIQ Character Driver"
36 Enable the creation of VCHIQ character driver. The cdev exposes
37 ioctls used by userspace libraries and testing tools to interact
38 with VideoCore, via the VCHIQ core driver (Check BCM2835_VCHIQ
41 This can be set to 'N' if the VideoCore communication is not
42 needed by userspace but only by other kernel modules
45 If not sure, set this to 'Y'.
