Video Output Switcher Control
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2006 luming.yu@intel.com
The output sysfs class driver provides an abstract video output layer that
can be used to hook platform specific methods to enable/disable video output
device through common sysfs interface. For example, on my IBM ThinkPad T42
laptop, The ACPI video driver registered its output devices and read/write
method for 'state' with output sysfs class. The user interface under sysfs is:
linux:/sys/class/video_output # tree .
