Public bug reported:
Hi there!
CPU frequency scaling doesn't work on my HP Pavilion dv6258eu notebook,
powernow-k8 seems to have problems with my BIOS, first some information:
Notebook Model: HP Pavilion dv6258eu
BIOS version: F.1A
System Board ID: 30B8
Processor Type: AMD Turion 64 X2 Mobile Technology TL-50 (1600MHz)
Memory: 2048 MB
(for full dmesg output see attached dmesg.out)
$ cat dmesg |grep powernow
[ 29.996000] powernow-k8: Found 2 AMD Turion(tm) 64 X2 Mobile Technology
TL-50 processors (version 2.00.00)
[ 29.996000] powernow-k8: MP systems not supported by PSB BIOS structure
[ 30.000000] powernow-k8: MP systems not supported by PSB BIOS structure
Probably it has to do with the missing/incomplete processor section of my
BIOSes ACPI-Table (see attached dsdt.dsl):
[...]
Scope (\_PR)
{
Processor (CPU0, 0x00, 0x00001010, 0x06) {}
Processor (CPU1, 0x01, 0x00001010, 0x06) {}
}
[...]
but I'm not sure how to fix that. I know about
http://acpi.sourceforge.net/dsdt/view.php, but there is no fixed DSDT
for my notebook.
Thanks in advance!
