kellis Posted July 21, 2010 Share Posted July 21, 2010 Hi guys, i have been trying to understand the ACPI specs, and analyzing my dsdt. I am starting to understand a few things, but i do have a few question. How does one actually know how to use ioreg and extract the values to then use that info and able to populate the dsdt accordingly. What are the steps in the whole process. What i am trying to do is that i have fixed my dsdt to have something pretty good, but i am investigating the backlight of the LCD in my laptop, now i don't want someone to actually just to do it for me, but to explain what the basic steps are, for example, grep this value using this tool, then convert to Xwhatever, then create a new method/device in the dsdt. (see i have no idea what that really involves as far as the steps go). Then, question about "actions": For example, if i wanted to let's say have the blutooth LED turn on or off, or even flash everytime i press the POWER button instead of bringing the Sleep popup. how does one would go about that? Also, I can't seem to find the FN keys in my dsdt, are they not reassignable from the dsdt? why is my ioreg showing P0P2 instead of GFX0? i know, so many questions, but after a few weeks of research, i don't think i am making that much progress, especially that my dsdt is not even close to what you guys have and the Intel ACPI specs help only up to a certain point. any help appreciated!!!!
