There are two places pointing to an unexisting "m.chehab@kernel.org" email. I never had such email, so, I'm unsure how it ends there. Anyway, it is plain wrong. While here, use my canonical e-mail on a bunch of places that are pointing to another e-mail. The idea is that, from now on, all places will be pointing to the same SMTP server.

Reading this file returns a list of available protocols,
|
|
something like:
|
|
"rc5 [rc6] nec jvc [sony]"
|
|
Enabled protocols are shown in [] brackets.
|
|
Writing "+proto" will add a protocol to the list of enabled
|
|
protocols.
|
|
Writing "-proto" will remove a protocol from the list of enabled
|
|
protocols.
|
|
Writing "proto" will enable only "proto".
|
|
Writing "none" will disable all protocols.
|
|
Write fails with EINVAL if an invalid protocol combination or
|
|
unknown protocol name is used.

Sets the scancode filter expected value.

Use in combination with /sys/class/rc/rcN/filter_mask to set the

expected value of the bits set in the filter mask.
|
|
If the hardware supports it then scancodes which do not match
|
|
the filter will be ignored. Otherwise the write will fail with

an error.

This value may be reset to 0 if the current protocol is altered.

|
|
Use in combination with /sys/class/rc/rcN/filter to set the bits

|
of the scancode which should be compared against the expected

|
value. A value of 0 disables the filter to allow all valid
|
|
scancodes to be processed.

If the hardware supports it then scancodes which do not match

Description:
|
|
Reading this file returns a list of available protocols to use
|
|
for the wakeup filter, something like:
|
|
"rc-5 nec nec-x rc-6-0 rc-6-6a-24 [rc-6-6a-32] rc-6-mce"
|
|
Note that protocol variants are listed, so "nec", "sony",
|
|
"rc-5", "rc-6" have their different bit length encodings
|
|
listed if available.
|
|
The enabled wakeup protocol is shown in [] brackets.
|
|
Only one protocol can be selected at a time.
|
|
Writing "proto" will use "proto" for wakeup events.
|
|
Writing "none" will disable wakeup.
|
|
Write fails with EINVAL if an invalid protocol combination or
|
|
unknown protocol name is used, or if wakeup is not supported by
|
|
the hardware.

Use in combination with /sys/class/rc/rcN/wakeup_filter_mask to
