Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  Enables a virtual video driver. This driver emulates a webcam,
	  TV, S-Video and HDMI capture hardware, including VBI support for
	  the SDTV inputs. Also video output, VBI output, radio receivers,
	  transmitters and software defined radio capture is emulated.

	  It is highly configurable and is ideal for testing applications.
	  Error injection is supported to test rare errors that are hard
	  to reproduce in real hardware.

	  Say Y here if you want to test video apps or debug V4L devices.
	  When in doubt, say N.

config VIDEO_VIVID_CEC
	bool "Enable CEC emulation support"
	depends on VIDEO_VIVID
	select CEC_CORE

	  When selected the vivid module will emulate the optional
	  HDMI CEC feature.

	help
	  This allows you to specify the maximum number of devices supported
	  by the vivid driver.
