 |
|
Has anybody managed to get powernow(-k8) working on a Abit AV8 motherboard? My processor is a Athlon64 3000+ Venice (90nm). I've got the latest BIOS version (1.9) with Cool'n'Quiet enabled, but powernow-k8 fails with
| Code: | powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.50.3)
powernow-k8: BIOS error - no PSB or ACPI _PSS objects
|
I am using gentoo-sources 2.6.13-r3:

I hope I did not forget anything important. Is there a problem with those settings? Are there special settings in the BIOS (other than enabling C'n'Q) that I should look at?
Thanks! |

| I think it's a kernel bug. 2.6.0 - 2.6.13 worked for me with powernow and now suddenly 2.6.14 won't. |

Thank you for your reply but I don't even have 2.6.14 yet. Got 2.6.13-r3 and this is the first kernel I tried on this board. I've already been searching the kernel changelog on kernel.org for something that might help but didn't find anything. I also looked through powernow-k8.h and find_psb_table where the error message comes from. There is the following advice:
| Code: | /*
* If you see this message, complain to BIOS manufacturer. If
* he tells you "we do not support Linux" or some similar
* nonsense, remember that Windows 2000 uses the same legacy
* mechanism that the old Linux PSB driver uses. Tell them it
* is broken with Windows 2000.
*
* The reference to the AMD documentation is chapter 9 in the
* BIOS and Kernel Developer's Guide, which is available on
* www.amd.com
*/
printk(KERN_INFO PFX "BIOS error - no PSB or ACPI _PSS objects\n");

I've been too lazy to install windows, but I could also not find anything about Abit & powernow not working on my board (Abit AV8) - thus, I assume that it should work and I would like to know why I don't get it to work. |

I have the same exact board and am running bios version 24 which is the latest for that board from Abit web site. I dont know where you got version 1.9.
I am running 2.6.13-r3 and it works fine for me. The only difference is that my processor is a 3000+ Winchester. So, maybe it is processor related...

Thanks a lot for this hint! I must have been on an old mirror for the driver. Updated to 24 and now the output is
| Quote: | powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.50.3)
powernow-k8: 0 : fid 0xa (1800 MHz), vid 0x6 (1400 mV)
powernow-k8: 1 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV) |
Great! |
