 Posted: Mon May 22, 2006 7:23 pm Post subject: Trouble getting powernow to work.. |
 |
|
I have a HP Pavilion ze4423ea. I haven't used it in quite a while, but I distinctly remember having run cpufreq on it approx 1.5 years ago. After that I had the bios updated and added a wlan mini-pci card, but that's it for hw changes.
Now I can't get the kernel to use my powernow hardware. Here's a snippet from /var/log/messages
| Code: | May 22 22:11:53 laptop TCP bic registered
May 22 22:11:53 laptop NET: Registered protocol family 1
May 22 22:11:53 laptop NET: Registered protocol family 17
May 22 22:11:53 laptop powernow: PowerNOW! Technology present. Can scale: frequency
and voltage.
May 22 22:11:53 laptop Using IPI Shortcut mode
May 22 22:11:53 laptop EXT3-fs: mounted filesystem with ordered data mode. |
Aka. just one row telling me that I have powernow, but then nothing, not even an error about missing PST tables. As far as I know, I have all the necessary stuff in my kernel:
| Code: | [*] CPU Frequency scaling
<*> 'powersave' governor
<*> 'userspace' governor for userspace frequency scaling
<*> 'ondemand' cpufreq policy governor
<*> 'conservative' cpufreq governor
<*> ACPI Processor P-States driver
<*> AMD Mobile Athlon/Duron PowerNow! |
Any idea what I'm doing wrong? |

How do you know your kernel doesn't use the PowerNow feature?

When I try to add the CPU Scaling Monitor Applet to the Gnome Panel I get this message: "You will not be able to modify the frequency of your machine. Your machine may be misconfigured or not have hardware support for CPU frequency scaling.". Also, I cant find a cpufreq-directory under/sys/devices/system/cpu/cpu0/, which would indicate that stuff isn't working correctly. |

Thanks, but I was already working according to that one. I changed powernow_k7 into a module, and when I try to load it I get the following:
| Code: | laptop ~ # modprobe powernow-k7
FATAL: Error inserting powernow_k7 (/lib/modules/2.6.16-gentoo-r8/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k7.ko): No such device |
When I do that I always get the following row into /var/log/messages:
| Code: | | powernow: PowerNOW! Technology present. Can scale: frequency and voltage. |
I'm guessing that I don't have some important drivers built, but I don't really know which ones to focus on. I added i2c-drivers for ALi1535 and watchdog drivers for ALi M7101, but that didn't seem to help any. Here's my lspci:
| Code: | laptop ~ # lspci
00:00.0 Host bridge: ATI Technologies Inc AGP Bridge [IGP 320M] (rev 13)
00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 320M] (rev 01)
00:02.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
00:06.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link Controller Audio Device (rev 02)

00:12.0 Ethernet controller: National Semiconductor Corporation DP83815 (MacPhyter) Ethernet Controller
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility U1 |
Any ideas where I should be looking? Getting ready to throw in the towel here.. |

could be a defection in the CPU, not very common but possible.
