|
In order to support very low power operation, the XO laptop uses a
|
|
secondary Display CONtroller, or DCON. This secondary controller
|
|
is present in the video pipeline between the primary display
|
|
controller (integrate into the processor or chipset) and the LCD
|
|
panel. It allows the main processor/display controller to be
|
|
completely powered off while still retaining an image on the display.
|
|
This controller is only available on OLPC platforms. Unless you have
|
|
one of these platforms, you will want to say 'N'.

Enable support for the DCON in XO-1 model laptops. The kernel
|
|
communicates with the DCON using model-specific code. If you
|

have an XO-1 (or if you're unsure what model you have), you should
|
|
say 'Y'.

Enable support for the DCON in XO-1.5 model laptops. The kernel

communicates with the DCON using model-specific code. If you
