After some more extensive testing I cannot confirm the regression anymore on my Panasonic CF-T5: forcing pcie_aspm and manually setting powersave: echo powersave /sys/module/pcie_aspm/parameters/policy solves the problem for me as well. From /proc/cpuinfo: vendor_id : GenuineIntel cpu family : 6 model : 14 model name : Genuine Intel(R) CPU U1400 @ 1.20GHz I made a script for pm-powersave, attached as pcie_aspm, and put it in /etc/pm/power.d I made a table to summarize the results of the tests, reporting powertop results on 4 hours Wakeups/s (lower=better), C3% (perc. of time in higest C state, higher=better), PLow% (perc. of time at lowest CPU freq, higher=better), battery duration (hh:mm, based on battery-stats log), avg temperatures of the two available sensors (estimate based on collectd graphs). All tests were run with screen brightness 10/21, dpms on (switching off the screen after 10min), wifi off (in normal conditions the battery lasts less then half the times obtained in the tests, but it's still pretty good). Kernel | Wakeups/s | C3% | PLow% | Power | Battery | Temp0 C | Temp1 C | 2.6.35-28.50 +aspm 50.7 93.6 77.0 5.8W 15:15 38 39 2.6.38-11.50 +aspm 53.7 94.4 81.8 4.0W 16:23 37 38 2.6.38-12.51 +aspm a 47.2 94.1 84.6 8.7W 8:57 38 42 2.6.38-12.51 +aspm b 46.1 93.2 70.24.8W 14:52 38 39 The thing I realized running the tests is that acpi estimate of battery state (and power) is not so reliable, therefore I had very different results with when starting the tests as soon as the charge was 100%, and when it was left powered for a few hours while at 100%. That was the only difference among the two runs with 2.6.38-12.51, marked a and b in the table. As you can see, repeating the test after some time with the ac adapter plugged in gave me results which are comparable to maverick.

Current way of rendering the GUI is dependent on CPU power, so battery on stronger processors runs longer, why, because the stronger CPU needs less time to render the GUI, it's just like in vehicles, as vehicle has more horsepower it consumes less fuel, because it takes less time to achieve the speed, and because GPU is 10 times stronger than CPU, battery on Windows lasts more.

Hello, I have a thinkpad x200 (sandy bridge), and I don't think my experience is very typical, but: I saw some of the same power regressions people are talking about, but I stuck with the latter kernels (I'm using 3.0.4 from the mainline site) because the older, energy-saving kernels had some trouble with the sandy bridge chip. In any case, I was using Natty+Gnome Classic, but a few days I decided to take the plunge and update to Oneiric+Unity, and low and behold, I'm seeing *much better* power performance *with the same kernel I was using before*. With Natty, I could barely get power consumption down to maybe 13 W (no bluetooth or network, etc). As I write this, with bluetooth off but wifi on, the laptop is drawing ~9W, and I still have 6h to go with 65% battery. Suffering occasional unity freezes, so not everything is sunny, but... One difference is that I set all the tunables using PowerTop, and the version that comes with Oneiric has more tunables than the previous one.

[Bug 760131] Re: Power consumption raised significantly in natty
@Julian - There are actually 3 power regressions discussed in this bug. The biggest one seems to have occurred between the 2.6.37 kernel and Natty's 2.6.38 kernel, when Active-State Power Management (ASPM) was disabled. This was done as some BIOS's have broken support for ASPM and linux will hang on those machines when trying to use ASPM. It was therefore decided to play it safe and disable ASPM in linux for all hardware. This power regression is not very hardware specific at all - it affects any machine with a PCI Express motherboard. You can force ASPM by adding pcie_aspm=force to your GRUB boot command line. This should work for many systems, but if your system's BIOS/hardware is in bad shape, you may get system hangs. The fix in comment #164 (on the basis of which this bug was marked as fixed, in combination with comment #168) corrects a much smaller power regression in EPB (energy/performance bias), specfically the value of MSR_IA32_ENERGY_PERF_BIAS. This in fact may not even be a regression, but simply a new addition of support for an energy-saving feature. It is very hardware specific - MSR_IA32_ENERGY_PERF_BIAS was only introduced in the recent Intel Westmere Xeon CPUs and the even more recent Intel Sandy Bridge CPUs. Older Intel hardware and non-Intel hardware does not use this MSR. You can also check whether your system supports this feature by looking for the epb flag in /proc/cpuinfo. Within the dmesg output should also be ENERGY_PERF_BIAS messages, if being used. It is worth noting that the original reporter of this bug has an older CPU that does not support the energy performance bias MSR. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 760131] Re: Power consumption raised significantly in natty
@ Tim Gardner and Leann Ogasawara - further to comment #209, particularly the last sentence, I have reviewed this bug. The author of comment #168 has not tested the patch from comment #164 which you refer to in comment #201. They performed a package-upgrade to linux-image 2.6.38-11 (which version we are not sure) before the patch was even in natty-proposed. Comment #195 is vague, and comment #196 is about hardware which does not support the energy performance bias MSR. Therefore, given the large number of subsequent comments stating that the patch has not reduced power consumption, and given the original reporter (I am led to believe they are a Canonical employee)'s hardware, can we really mark this bug as Fix Released, or even as Fix Committed? However, marking as verification done for the SRU for the energy performance bias MSR seems appropriate - I agree with comment #200. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

One more data point. On my Lenovo ThinkPad T410 (so, same as in comment #168) I was able to recover most of the Maverick-like battery life by updating to the newest BIOS. Before the upgrade powertop showed ~25W of battery drain w/o tuning, with pcie_aspm=force and all powertop suggestions done it went down to ~20W, and after the BIOS upgrade it is 16-17W, which is only slightly worse than with Maverick. It can be further improved, now powertop shows the soundcard x2 taking 1.7W and used 100% (when no sound is played), that I will report separately. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 760131] Re: Power consumption raised significantly in natty
Aside from the fact that this is unrelated to a power regression: Is the ubuntu/linux power consumption bug really device-specific? On my Thinkpad X60s, ubuntu uses at least 4 Watts more as Windows does: roughly 12W instead of 8W (thats 50%) . I haven't seen a single device since my good old T40, which actually consumes LESS OR EQUAL power when running linux. Note the fact that Thinkpads are probably the best supported notebooks.. Now Intel claims to care about this (you all know powertop from http://www.lesswatts.org), but nothing seems to change. I think, as some people already mentioned, as the ubuntu-community seems to care about mobile devices (it seems they do), they should care more about power consumption. Closing a bug without a solution doesn't do it for me. Sorry for polluting this bug even more. And btw, if anybody knows a (sub-)notebook (preferably featuring a trackpoint) with minimal power consumption on linux , please tell me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Maybe this issue would need special attention from Apport application, an if in it's code, to be able to add multiple sets of attachments on the same bug (attachments from different people; as it is now, if the bug is there already you cannot automatically attach your logs). I think it will also be easier for developers to have it all in one place than having hundreds of separate bugs.

Apparently, there is no fix for this bug yet, proof is here: http://www.phoronix.com/scan.php?page=articleitem=ubuntu_linux_epbnum=1 Quoting the article: What Canonical's kernel team says is the fix to LP #760131 is an unrelated power fix done upstream to ensure that the MSR_IA32_ENERGY_PERF_BIAS register is set to normal rather than performance mode. The hardware in the original posting to the aforementioned bug report does not even support EPB and is about ASPM and other power changes causing the significantly higher power usage. As these latest tests from the Sandy Bridge notebook show, the 3.0.1+ kernels can improve the power efficiency without degrading the system performance, but will only help you if running the latest Intel hardware that supports the energy performance bias feature.

Just to add a counterpoint, I've found that things are more or less working well for me with the new kernel - it's definitely better then the earlier versions.

If you have a power consumption which is good/expected with 2.6.38-11.50 kernel, and it's bad with 2.6.38-12.51 kernel, likely there is a regression, in this case please report here. Regressions from another natty versions should be in a separate bug report. In case none of the kernels since natty release had good/expected power consumption on your machine, likely you have a different bug from this one (typically hardware specific requiring different fixes). It's hard to isolate problems with all mixed reports here. In this case please open a new bug as already requested. ** Tags added: verification-needed-natty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The patch noted in comment #164 was applied to Oneiric when the Oneiric kernel was rebased to upstream stable v3.0.1. It was subsequently uploaded and available in Oneiric as of linux-3.0.0-8.10. I'm therefore marking the Oneiric task Fix Released.

[Bug 760131] Re: Power consumption raised significantly in natty
SRU Justification: Impact: Since 2.6.36 (23016bf0d25), Linux prints the existence of epb in /proc/cpuinfo, Since 2.6.38 (d5532ee7b40), the x86_energy_perf_policy(8) utility has been available in-tree to update MSR_IA32_ENERGY_PERF_BIAS. However, the typical BIOS fails to initialize the MSR, presumably because this is handled by high-volume shrink-wrap operating systems... Linux distros, on the other hand, do not yet invoke x86_energy_perf_policy(8). As a result, WSM-EP, SNB, and later hardware from Intel will run in its default hardware power-on state (performance), which assumes that users care for performance at all costs and not for energy efficiency. While that is fine for performance benchmarks, the hardware's intended default operating point is normal mode... Initialize the MSR to the normal by default during kernel boot. x86_energy_perf_policy(8) is available to change the default after boot, should the user have a different preference.

[Bug 760131] Re: Power consumption raised significantly in natty
Even if that were so, when my laptop goes into battery mode, with all of the aggressive power saving modes throttling the CPU, etc, it's unacceptable for it to be running so hot. I wouldn't normally care if it's plugged in and sucking up power, but when the power is supposed to be scaled back, it shouldn't be taking up more power ( even at the cost of decreased responsiveness.) In any case, as of yesterday, after a kernel update, my laptop is now consuming 14-17W of power when on battery, as opposed to the 19-25W it was taking last week. While not as good as the 11-14W range I had going with Maverick, it's an improvement. I don't recall seeing anything in the kernel changelog that would indicate a change to the power consumption, but I'm not a kernel expert. In any case, I have not altered any of my power saving optimizations between the two tests, and I had used the force acpi trick much earlier on. If it stays this way for now, that's not a bad sign. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 760131] Re: Power consumption raised significantly in natty
Yes, you got the right idea. I don't know that it is really dangerous - worst case would be your driver wouldn't load or lock up, a reboot would fix it. My scenario works for the iwlagn driver, I don't know if you have the same hardware. It does make a 2 - 3 watt difference in power usage for me. I don't know why this changed as it worked automatically in the 2.6.35 tree, but not now. I have a script manually perform the setpci mods before the kernel loads the iwlagn driver which takes care of it for now. On a different note, there have been a few posts for eepc's in the thread, the natty kernel didn't have the WMI modules enabled for them. Maverick did, there was a commit in the oneiric tree that put them back in - that should correct that issue. If you run one of those, try the current kernel, I think it is 3.0.0-8 right now.

[Bug 760131] Re: Power consumption raised significantly in natty
@Erwin - not sure if you have this same hardware as mine, but I did find what makes the difference for my laptop. Natty running 2.6.35 kernel, can idle at 18.5 watts - runs ok, but I find that power management screws up my primary drive when it goes to sleep, will not wake up the drive at all, system just locks hard - on Seagate Hybrid drive. On Western Digital drive - no issues with wake up. realtek based intel-hda shows ASPM unknown and disabled sudo lspci -vvv shows that most things run with ASPM enabled, iwlagn, usb ports, half of the PCIE ports, and the video (Nvidia-running binary blob) Natty running default kernel 2.6.38 - Even with pcie_aspm=force, iwlagn and the pcie root it sits on has ASPM disabled for some reason. intel- hda still not supporting ASPM - Idle with powertop shows my system it at 21.5 watts. Natty running current upstream oneiric builds, 3.0.0.8. ASPM is the same, the kernel tweaks found after 2.6.38 with the idle changes helps some, best idle level is about 20 watts Natty running upstream vanilla from git.kernel.org, ASPM works for the intel-hda card. iwlagn still is not enabling ASPM. Idle is at 19.8 watts found good info at http://linuxwireless.org/en/users/Documentation/ASPM using that page, I looked at the output from LSPCI for the wireless card and the PCIe root for it, found that the bits were not set for aspm (hex= 0x40) I unloaded the iwlagn driver and changed to 0x43 for the root and the iwlagn stuff, then modprobe iwlagn again.. ASPM then shows it is working, - and confirm it works with the 2.6.38 kernel all the way up to the upstream sources - 3.0.0.8 and the vanilla source. with the oneiric kernel, I seem to get the best results, 17.8 for idle wattage.. better than the maverick sources. the pcie_aspm=force is only a workaround needed if your bios isn't set up right. if you run 'dmesg | grep OSC' I see [2.061987] pci:00: Requesting ACPI _OSC control (0x1d) [2.061992] pci:00: ACPI _OSC request failed (AE_NOT_FOUND), returned control mask: 0x1d [2.061995] ACPI _OSC control for PCIe not granted, disabling ASPM on the laptop, where it helps, but on another desktop -- [0.716560] pci:00: Requesting ACPI _OSC control (0x1d) [0.717137] pci:00: ACPI _OSC control (0x15) granted where the pcie_aspm=force does nothing at all.. ** Attachment added: system testing info https://bugs.launchpad.net/ubuntu/+source/linux/+bug/760131/+attachment/2265178/+files/submission.xml -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
