Sorry, i was totally out of line for a few days. clone the github code and edit the test-off.sh file to add the methods found in the DDST/SSDT.
A classical hacking would seems like : $ git clone https://github.com/peberlein/acpi_call.git $ cd acpi_call $ make $ sudo insmod acpi_call.ko $ $EDITOR test-off.sh # add one method in the methods list $ ./test-off.sh - test 1 per 1 your methods 1 per line after trying the next step. - After that, check the energy consumption. If no goods after each method call, you can try to read and demystify the SSDT/DDST to figure out if the methods can take paramters, refer you for example in the m11xr2.sh script which is in this case. In my SSDT2.dsl (i have an m11xr2 ;) ) i have the following code: Return (\_SB.PCI0.P0P2.PEGP.NVOP (Arg0, Arg1, Arg2, Arg3)) Which indicates that the method take some parameters. When you find that, you still have to determine the parameters to set :p Le 08/01/2011 21:55, Florian Mauracher a écrit : > Hi > > thanks for the hint with the SSDT. > I was successful in extracting it, but as you might have noticed I'm > completely new to this acpi issue. > > Here are all the DSDT and SSDT files, if you want to have a look at it: :-) > http://www.mauracher.eu/static/acpi/ > > Like that the only thing I could do was going through these files while > grepping for "Method". > > These are all calls I found working out of the SSDT1.dsl: > \_SB.PCI0.P0P2._STA 0xf > \_SB.PCI0.P0P2.PEGP._INI 0x51301558 > \_SB.PCI0.P0P2.PEGP._STA 0xf > \_SB.PCI0.P0P2.PEGP._ROM 2Args req?
