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.

menuconfig RC_CORE
	tristate "Remote Controller support"
	depends on INPUT
	help
	  Enable support for Remote Controllers on Linux. This is
	  needed in order to support several video capture adapters,
	  standalone IR receivers/transmitters, and RF receivers.

	  Enable this option if you have a video capture board even
	  if you don't need IR, as otherwise, you may not be able to
	  compile the driver for your adapter.

	  Say Y when you have a TV or an IR device.

if RC_CORE

config BPF_LIRC_MODE2
	bool "Support for eBPF programs attached to lirc devices"
	depends on BPF_SYSCALL
	depends on RC_CORE=y
	depends on LIRC
	help
	   Allow attaching eBPF programs to a lirc device using the bpf(2)
	   syscall command BPF_PROG_ATTACH. This is supported for raw IR
	   receivers.

	   These eBPF programs can be used to decode IR into scancodes, for
	   IR protocols not supported by the kernel decoders.

config LIRC
	bool "LIRC user interface"
	help
	   Enable this option to enable the Linux Infrared Remote
	   Control user interface (e.g. /dev/lirc*). This interface
	   passes raw IR to and from userspace, which is needed for
	   IR transmitting (aka "blasting") and for the lirc daemon.

menuconfig RC_DECODERS
	bool "Remote controller decoders"

if RC_DECODERS

config IR_IMON_DECODER
	tristate "Enable IR raw decoder for the iMON protocol"
	help
	   Enable this option if you have iMON PAD or Antec Veris infrared
	   remote control and you would like to use it with a raw IR
	   receiver, or if you wish to use an encoder to transmit this IR.

config IR_JVC_DECODER
	tristate "Enable IR raw decoder for the JVC protocol"
	select BITREVERSE

	help
	   Enable this option if you have an infrared remote control which
	   uses the JVC protocol, and you need software decoding support.

config IR_MCE_KBD_DECODER
	tristate "Enable IR raw decoder for the MCE keyboard/mouse protocol"
	select BITREVERSE

	help
	   Enable this option if you have a Microsoft Remote Keyboard for
	   Windows Media Center Edition, which you would like to use with
	   a raw IR receiver in your system.
