8.1 IrDA in the Kernel

Most modern kernels have all the support that you
need to get infrared to work. If you build your own kernel, make sure
that you've enabled infrared support. Most of the
infrared support is configured under the IrDA (Infrared) Support
section that appears in the kernel configuration. Figure 8-2 shows the make menuconfig
kernel configuration screen open to the IrDA Support section. (You
may need to select Prompt for development and/or incomplete
code/drivers under the top-level Code maturity level options section
of the kernel configuration to see all the available options.)

Figure 8-2. Configuring IrDA support with make menuconfig

You'll definitely want to configure
IrDA Subsystem
Support (CONFIG_IRDA) as well as the
IrCOMM Protocol
(CONFIG_IRCOMM), which lets you use the IrDA port as a serial port
via one of the /dev/ircommN ports. We suggest
that you compile these as modules and go into Infrared-port Device
Drivers and select every driver that it offers you, configuring each
as a module.
