Subject: Missing PSB or _PSS in BIOS
Date: Sun, 19 Feb 2006 02:45:06 +0100 [thread overview]
Message-ID: <43F7CDA2.8030209@online.fr> (raw)
Hello,
I'm using an opteron 165 (dual-core) which frequency/voltage should
be able to be scaled, but unfortunately the latest BIOS for my motherboard
lacks the frequency transition tables needed by powernow-k8.c
as shown by the boot message:
powernow-k8: MP systems not supported by PSB BIOS structure
powernow-k8: BIOS error - no PSB or ACPI _PSS objects
Would it be possible to write suitable ACPI _PSS from AMD processor
documentation ?
Or take the infos from some other ACPI BIOS which has support, and put
it in mine ?
And use the "ACPI load custom DSDT" kernel option to get the patched one
used by the
powernow-k8 driver ?
I found a lot of infos about fixing glitches in DSDT but could not find
anything
about adding missing _PSS entries...
Would that be dangerous ?
Is there something else I could do ?
I don't think I'll get an answer from the vendor, even if I tried...
Please, keep me on the CC list
