irdm.conf has details of your SDR device. Full details can be found here. An example for using an RTL-SDR with max gain and bias-tee enabled:

[osmosdr-source]
sample_rate=2500000
center_freq=1625600000

# Uncomment to use the RTL-SDR's Bias Tee if available
device_args='rtl=0,bias=1'

# Automatic bandwidth
bandwidth=0

# LNA gain
gain=49.6
