|
|
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.

|
|
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'.
