What: /sys/class/rc/ |

|
Description: |
|
The rc/ class sub-directory belongs to the Remote Controller |
|
core and provides a sysfs interface for configuring infrared |
|
remote controller receivers. |

|
KernelVersion: 2.6.35 |
|
Contact: Mauro Carvalho Chehab <[email protected]> |
|
Description: |
|
A /sys/class/rc/rcN directory is created for each remote |
|
control receiver device where N is the number of the receiver. |
|

Description: |
|
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. |
|

What: /sys/class/rc/rcN/filter |
|
Date: Jan 2014 |
|
KernelVersion: 3.15 |
|
Contact: Mauro Carvalho Chehab <[email protected]> |
|
Description: |
|
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. |

Description: |
|
Sets the scancode filter mask of bits to compare. |
|
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 |
|
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. |

What: /sys/class/rc/rcN/wakeup_protocols |
|
Date: Feb 2017 |
|
KernelVersion: 4.11 |
|
Contact: Mauro Carvalho Chehab <[email protected]> |
|
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. |

Description: |
|
Sets the scancode wakeup filter expected value. |
|
|
|
Use in combination with /sys/class/rc/rcN/wakeup_filter_mask to |
|
set the expected value of the bits set in the wakeup filter mask |
|
to trigger a system wake event. |
|
|
|
If the hardware supports it and wakeup_filter_mask is not 0 then |
|
scancodes which match the filter will wake the system from e.g. |
|
suspend to RAM or power off. |
|
|
|
Otherwise the write will fail with an error. |
|
|
|
This value may be reset to 0 if the wakeup protocol is altered. |
