[Bug 109197] Re: kde-guidance-powermanager: support conservative CPUFreq gouvernor
The cpufreq developers disagree on that. And I strongly disagree on that. On my notebook, 1000MHz is a lot faster that 800MHz, because it makes the memory clock and access-time much faster. It's not just the CPU that scales up. But anyone should understand that conservative is still better that performance. At least when I filed the bug, either ondemand, userspace, performance or powersave was the cpufreq policy for dynamic in that order. -- kde-guidance-powermanager: support conservative CPUFreq gouvernor https://bugs.launchpad.net/bugs/109197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

David I share your view, but there seems to be much new information showing it other wise.

[Bug 109197] Re: kde-guidance-powermanager: support conservative CPUFreq gouvernor
The most important point of this bugreport was to get conservative support into guidance-power-manager, not necessarily as the preferred- over-ondemand one. But without ondemand, conservative should be the alternative, not powersave as that is not a dynamic cpufreq policy at all. -- kde-guidance-powermanager: support conservative CPUFreq gouvernor https://bugs.launchpad.net/bugs/109197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I was hesitating a bit, but apparently this bug has been fixed, conservative is now considered a dynamic cpufreq policy. ** Changed in: guidance-power-manager (Ubuntu) Status: Invalid = Fix Released -- kde-guidance-powermanager: support conservative CPUFreq gouvernor https://bugs.launchpad.net/bugs/109197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 109197] Re: kde-guidance-powermanager: support conservative CPUFreq gouvernor
I would agree that David's proposal is fine, so we would only redefine the meaning of Dynamic to try the following modes (in this order): - on AC: ondemand, conservative, userspace - on battery: conservative, ondemand, userspace I can work on this patch for Feisty+1 (probably in next day or two). -- kde-guidance-powermanager: support conservative CPUFreq gouvernor https://bugs.launchpad.net/bugs/109197 You received this bug notification because you are a member of Kubuntu Team, which is a bug contact for kde-guidance in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

that's fine with me. It wouldn't hurt either to use conservative in both situations, but I'd prefer to use ondemand on AC.

[Bug 109197] Re: kde-guidance-powermanager: support conservative CPUFreq gouvernor
Hi David, First, thanks for the patch. There are some tab/space issues in there, this *might* work, but it's broken -- don't mix space with tabs in python scripts. As to the actual functionality: I'm inclined to not merge it. Powermanager should be kept simple, we decided (together with usability folks) that we don't want a one-to-one mapping of cpufreq governors with cpu frequency policies. Instead, we decided to offer dynamic (basically what ondemand does), performance and powersave. I think adding conservative would be confusing to the user.

[Bug 109197] Re: kde-guidance-powermanager: support conservative CPUFreq gouvernor
Hi Sebas, Odd, kate shows no spaces/tabs inconsistencies at all... As a python hacker I know how important this is. Maybe a upload/download bug? (The only thing I can find is some trailing spaces on the original and existing trivial inconsistencies... ;-) ) Anyway, I agree Powermanager should be kept simple. However, I don't but that does not mean you should ignore the conservative governor. I propose this change: On AC, use ['dynamic', 'conservative', 'userspace'] in that order. On Battery, use ['conservative', 'dynamic', 'userspace'] in that order.

FYI, conservative is a dynamic governor optimized for battery usage. ondemand is a dynamic governor optimized for AC usage... IMHO, it's no loss using conservative on AC power.

Hi David, The lines starting with action use tabs (but as you state, there is some inconsistency in the released code as well (it's fixed in SVN already, that's also why I double-checked). I do not understand your rationale, however. For example: - Why should we use 'userspace' at all (there is no option to set the cpufrequency directly, which is the whole point of that governor) - What is the advantage of 'conservative' over 'powersave' (I guess that would be the easiest to follow path)?

[Bug 109197] Re: kde-guidance-powermanager: support conservative CPUFreq gouvernor
- We seem to be using userspace at the moment as a fallback for ondemand (see powermanage.py). Removing this is out of the scope of this bug/feature-request. - powersave is not a dynamic governor, it is plain the slowest frequency possible. (In contrary to Performance, which is plain the fastest frequency). See Documentation/cpu-freq/governors.txt in any recent kernel: -- The CPUfreq governor conservative, much like the ondemand governor, sets the CPU depending on the current usage. It differs in behaviour in that it gracefully increases and decreases the CPU speed rather than jumping to max speed the moment there is any load on the CPU. This behaviour more suitable in a battery powered environment. -- -- kde-guidance-powermanager: support conservative CPUFreq gouvernor https://bugs.launchpad.net/bugs/109197 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
