Description:
The CEC Framework allows for CEC error injection commands through
debugfs. Drivers that support this will create an error-inj file through which the error injection commands can be given.
The basic syntax is as follows:
Leadingspaces/tabs are ignored. If the nextcharacteris a '#'or the endof the line was reached, then the whole lineis ignored. Otherwise
a command is expected.
It isupto the driver to decide what commands to implement. The only exceptionis that the command 'clear' without any arguments must be
implemented and that it will remove all current error injection
commands.
This ensures that you can always do 'echo clear >error-inj'to clear any error injections without having to know the details of the driver-specific
commands.
Note that the outputof'error-inj' shall be valid as inputto'error-inj'.
So this must work::
Otherthan these basic rules described above this ABI isnot considered
stable and may change in the future.
Drivers that implement this functionality must document the commands as
part of the CEC documentation and must keep that documentation uptodate when changes are made.
The following CEC error injection implementations exist:
