Hi!
I'm using linux on a old Arcer Aspire 5315. I replaced sometime ago the original CPU by a T8100
I know that this forum not is focused on linux, but is the best resource that I know about DSDT modifications.
This is my current DSDT
The computer works fine but the are some issues that maybe I can fix with a proper DSDT
The CPU is working at 2 Ghz but should be 2.1 Ghz
It's a BIOS limitation that I need to fix
root@antiX1:/home/Carlos/Bios# cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit
2001000
I found this during boot
[ 2.218733] [Firmware Bug]: ACPI: Invalid BIOS _PSS frequency found for processor 0: 0x0 MHz
[ 2.218904] [Firmware Bug]: ACPI: Invalid BIOS _PSS frequency found for processor 1: 0x0 MHz
I suppose that is due my DSDT
Scope (_PR)
{
Processor (CPU0, 0x01, 0x00000410, 0x06) {}
Processor (CPU1, 0x02, 0x00000410, 0x06) {}
}
In a correct system the CPU should work from 800 MHz to 2.10 GHz
I'm confused about how populate that section... looks like I need to put the values for my current CPU (T8100) but...
-BIOS is supposed to works with a full range of CPUs, why I need to put my current one a not something valid for a entire family of CPUs?
In any case... i have found come calculators to generate the section but all are for Mac SO.
There is some SpeedStep calculator that works on windows/Linux? if not... how can I calculate the correct values?
