Helper function bpf_rc_repeat
Definition
Copyright (c) 2015 The Libbpf Authors. All rights reserved.
This helper is used in programs implementing IR decoding, to report a successfully decoded repeat key message. This delays the generation of a key up event for previously generated key down event.
Some IR protocols like NEC have a special IR message for repeating last button, for when a button is held down.
The ctx should point to the lirc sample as passed into the program.
This helper is only available is the kernel was compiled with the CONFIG_BPF_LIRC_MODE2 configuration option set to "y".
