|---|---|---|
| mjg59 | popey: Like I said, the lack of throttling isn't a problem | 12:49 |
| mjg59 | So regardless of anything else, the bug is mistitled :) | 12:50 |
| popey | heh | 12:50 |
| popey | suggestions welcome then | 12:51 |
| mjg59 | But yeah, the scaling stuff looks utterly funted | 12:53 |
| mjg59 | What hardware is this? | 12:53 |
| popey | tosh tablet laptop | 12:53 |
| mjg59 | Other than that, the failures are fairly harmless | 12:53 |
| mjg59 | Does Windows scale it correctly? | 12:53 |
| popey | it doesnt feel quick though | 12:54 |
| popey | dunno, dont use windows | 12:54 |
| mjg59 | Right, the scaling brokenness is probably killing performance | 12:54 |
| mjg59 | If you run something cpu intensive, do the values in /proc/cpuinfo rise? | 12:54 |
| popey | it always sits at 2GHz | 12:55 |
| popey | never changes | 12:55 |
| mjg59 | Yeah, that's fucked | 12:55 |
| popey | my apologies if i disappear.. on ropey wifi at UDS | 12:55 |
| mjg59 | Also, don't use powernowd directly - the init script should just be setting up ondemand and leaving it up to the kernel | 12:56 |
| popey | ok | 12:56 |
| mjg59 | Can you try unloading speedstep_centrino and load acpi-cupfreq instead? | 12:56 |
| popey | sure | 12:57 |
| popey | speedstep_centrino isnt currently loaded | 12:57 |
| mjg59 | ... | 12:57 |
| mjg59 | Ok, so that's a pretty poor sign to begin wth | 12:57 |
| popey | acpi_cpufreq is | 12:57 |
| mjg59 | Ok, that might explain it | 12:57 |
| mjg59 | In that case, try unloading acpi-cpufreq and load speedstep-centrino | 12:57 |
| popey | ok | 12:58 |
| popey | FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.20-15-generic/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device | 12:58 |
| mjg59 | Anything appear in dmesg then? | 12:58 |
| popey | no, but I get a lot of these all the time:- | 12:58 |
| popey | [ 5424.824000] APIC error on CPU0: 40(40) | 12:59 |
| popey | [ 5424.824000] APIC error on CPU1: 40(40) | 12:59 |
| mjg59 | Ok. I think you'll need to work with Ben to figure out why speedstep-centrino isn't working. In theory, the acpi_cpufreq stuff should work. | 01:00 |
| popey | heh, spoke to ben the other day, he said "it's broken" | 01:00 |
| mjg59 | Well, that's the obvious conclusion | 01:00 |
| popey | well, actually said "sounds liek hardware failure" | 01:00 |
| mjg59 | What was the bios option that you changed actually called? | 01:01 |
| popey | sorry, can't remember, it was something about cpu scaling | 01:01 |
| popey | but not the word scaling | 01:01 |
| popey | will check in the morning when i reboot | 01:02 |
| mjg59 | It may be that that needs to be enabled | 01:02 |
| popey | is this the kind of thing that might be fixed by a bios update or is it more likely to be a kernel thing do you think? | 01:02 |
| mjg59 | Sounds like a bios thing | 01:02 |
| popey | ok, will re-enable when i boot in the morning and try the speedstep_centrino module, thanks | 01:03 |

| popey | meh, couldn't waity | 01:11 |
| popey | it is called "Dynamic CPU Frequency Scaling" - I had it set to "Always high", now it is "Dynamically Switchable" | 01:11 |
| mjg59 | Ok | 01:11 |
| popey | (last option is "always low") | 01:11 |
| mjg59 | "Dynamically Switchable" sounds like the right value | 01:12 |
| popey | cpuinfo says 1GHz | 01:12 |
| mjg59 | Ok. If you do something that loads the CPU (like dd if=/dev/zero of=/dev/null) does that rise? | 01:12 |
| popey | alan@mother:/proc/acpi/processor/CPU0$ cat throttling | 01:12 |
| popey | <not supported> | 01:12 |
| popey | one mo | 01:12 |
| popey | yes | 01:13 |
| popey | cpuinfo says 2GHz now | 01:13 |
| mjg59 | Ok. So that works. | 01:13 |
| mjg59 | throttling isn't the same thing as frequency scaling | 01:13 |
| popey | and back to 1Ghz | 01:13 |
| popey | ah, ok | 01:13 |
| mjg59 | Throttling just drops the clock rate of the processor. It doesn't drop the voltage. As a result, it's entirely useless for anything other than emergency limitation, and even then scaling is preferable. | 01:14 |
| popey | right | 01:14 |
| mjg59 | So don't worry about the lack of throttling | 01:14 |
| popey | wilco | 01:14 |
| mjg59 | Based on your descriptions, everything now sounds fine except for the oddly low performance | 01:14 |
| mjg59 | Which is somewhat trickier to track down... | 01:15 |
| mjg59 | Your laptop probably has less cache than the desktop machine, but I would expect that to make a huge difference in the case you're describing | 01:15 |
| popey | kind of a bummer when i was hoping to do some cpu intensive stuff with this thing :( | 01:15 |
| mjg59 | I'd recommend some more solid benchmarking | 01:15 |
| popey | ok, the unix bench thing? | 01:16 |
| popey | Byte Unix Benchmark | 01:16 |
| mjg59 | For instance | 01:16 |
| mjg59 | I've never done any heavy CPU benchmarking, so... | 01:16 |
| popey | http://hants.lug.org.uk/cgi-bin/wiki.pl?ByteUNIXBenchmark is the kind of thing | 01:16 |
| popey | which seems relatively comprehensive | 01:17 |
| popey | thanks for the time spent on this mjg59, another beer in the nudge bank | 01:19 |

| Fahuadai | I have heard that 7.04 has inproved support for broadcom wireless cards including the bcm43** series. I've been trying for a while to get wpa2 working on a university network with no luck so far. | 12:58 |
| Fahuadai | would upgrading to 7.04 help? | 12:59 |

| elcuco | hi | 06:53 |
| elcuco | I am using Kubuntu 6.10 (in 2 hours 7.04) on a Lenovo 3000 N100, and found this site: | 06:54 |
| elcuco | https://wiki.ubuntu.com/LaptopTestingTeam/Lenovo3000N100 | 06:54 |
| elcuco | some things are not exactly corrent in that wiki page. | 06:55 |
| elcuco | for example external monitor did not work for me on the 7.04 livecd | 06:55 |
| elcuco | screen is not detected out of the box (915 resolution) | 06:55 |
| === elcuco is editing the page | ||
| crimsun | elcuco: you need to use xserver-xorg-video-intel, of coure. | 08:46 |
| crimsun | course ^ | 08:46 |
| crimsun | forget xserver-xorg-video-i810 + 915resolution | 08:46 |
