About DSDT fixing and debugging

About DSDT fixing and debugging

[Gaetano Sferra]

Hello to all,
I'm reading the ACPI specification to try to fix my DSDT (Amilo D 7830) that
seems to be badly written
because there are several errors while comiling it with IASL (statements in
wrong place and poor control
methods definitions) but I've some questions about the DSDT functionality and
debugging.
a) Is there a debugger (something like gdb) or a sinulator to test the DSDT without
patching the kernel and load it?
b) Looking in the acpi log files (/proc/acpi) the cooling system reports <not
supported>, the
temperature stills on 75 C, and the processor state stills on C1 (12%). Can this
condition be fixed
throught the DSDT (eg. checking the _TZ notifies and the _AC methods)?

Thanks to all for the support and the great work...

just want to say that these are exactly the same problems i have with my fujitsu amilo D 7830!
no throttling (always C1 = 12%), no cooling (always 75° C). i have already disassembled with a few 
errors, but couldn't fix it correctly.

Gaetano, when you'll have fixed it, could you send me your dsdt? this would be very nice... 

thanks for your great job

about the C1 states: does your DSDT have a PBLK_lenght != [0|6]? Please
see post [1] on ACPI-devel (sorry, I don't know how you can see the
whole thread with gmane.com) and the first integration _CST method [2].

Thx, bye,

I think OP meant s/C1/T1 ;)

didn't find PBLK_length in my dsdt.dsl because...

yes, i've really meant T1 = 12%... i was talking about the throttling 
state.

question: does a pentium 4 (not mobile) in a laptop support C2/C3? (i 
mean the processor states  when the cpu doesn't have much work!)

thank you guys
