Subject: powernow-k8: missing p-state
Date: Sun, 7 Aug 2005 18:13:46 -0600 [thread overview]
Message-ID: <3f72be670508071713510f5697@mail.gmail.com> (raw)
I have an AMD 64 3200+ processor with 4 p-states (according to AMD
specs), with frequencies of 1.0, 1.8, 2.0, and 2.2 GHz. On boot
(Fedora Core 4, kernel 2.6.12), however, the powernow-k8 module only
recognises the highest three frequencies
powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.40.2)
powernow-k8: 0 : fid 0xe (2200 MHz), vid 0x2 (1500 mV)
powernow-k8: 1 : fid 0xc (2000 MHz), vid 0x6 (1400 mV)
powernow-k8: 2 : fid 0xa (1800 MHz), vid 0xa (1300 mV)
My guess is that this problem is due to a buggy BIOS. Are there any existing
solutions to this problem? Given the apparent number of AMD 64 motherboards
with similar problems, surely it would be useful to be able to specify
the p-state
table as a configuration option for the powernow-k8 module?
