Hi
This is my first post to the list. Hope I will find a solution.
I am trying to develop a new functionality using a Sun alonso Quad Core blade (x86_64) architecture.
The linux distribution which I am using contains a very old acpi driver (02/09/2005 probably acpi version 1 compliant)
Further, the BIOS I am using is an AMI BIOS. I am fairly certain that it is acpi version 3 compliant.
Now, I am facing two problems here.
1) I am trying to evaluate some namespace control methods which are setup in sytem DSDT.
Functions are :
\\_SB.PERB (should contain memory location address) and
\\_SB.PERL (should contain length)
This some information passed to us from BIOS which is required for my development.
I am using acpi_evaluate_object to evaluate these functions. I dont see any error in executing the evaluate
function call. But they evaluate to zero.
2) The second task I have is to put the system into S3 (suspend to ram) state.
While doing that I am experiencing a problem. Every time I write
echo mem > /sys/power/state
System hangs at METHOD_NAME__PTS method. There is a related bug in
new acpi driver related to this function. But since I am using a very old driver this should not have
happened.
Just for added information : I dont really care about resume from the S3 state. I dont have video card.
Any help in this regard is highly appreciated.
Thanks,
