Whooo! With the latest package-upgrade (i.e. linux-image 2.6.38-11) for Natty, the Idle Power consumption reported by powertop on my TP T410 went down *more than 50%*: From around 25W to below 12W.

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.

Out of curiosity: Why Linux have this problem and Windows don't? This is not a troll.

This is a permanent condition because it is a new setting of the Linux kernel, and nobody in power considers it a bug, nor a very important issue. Sorry. There isn't any easy 'solution' to improve this situation beyond affected users forcing the PCI-E Active-State Power Management using the pcie_aspm=force kernel command line option. Jesse thinks that more Linux drivers will end up needing to set the ASPM bits directly as a long-term solution. There's just too many hardware devices that don't properly support the ASPM power-saving modes. The only alternative would be to create a big white-list of supported devices, but that comes down to being effectively the same large task as just having the driver set the appropriate bit. So there won't be any magic fix in the Linux 3.0 kernel nor will there likely be any major change in the Linux 3.1 kernel without suddenly a bunch of drivers handling the Active-State Power Management bit. For now, mobile users just need to know to force the PCI-E ASPM support if needed to maximize the Linux battery life. -- 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
that is the interesting question. There isn't really a large discrepancy for the most part. Phoronix did a piece comparing ubuntu to windows 7, and they actually were rather close. http://www.phoronix.com/scan.php?page=articleitem=windows_ubuntu_pownum=1 that said, there are a few reasons why Natty ends up using more power than previous versions.. the biggest is the ASPI changes to the kernel. Basically, there are some devices that could lock up the boot process as earlier versions would boot up. The kernel devs changed the behavior of the linux kernel, now it does not assume it can implement ASPM, it will query the ACPI bits in the BIOS on your computer if it can. Before this, it didn't check, it would turn it on regardless. Unfortunately, as these things go, many BIOS out there SUCK. Most manufacturers do little testing (as in none) to make sure their bios works according to established standards, and usually if it works with Windows, they ship it, and don't really care afterwards. Now that the Linux kernel is being polite, (and following actual ACPI standards) many devices will not report proper information to hand off to the Kernel. So Linux will now assume it can't touch it, and ASPM is disabled on the devices. for the most part, you can override this with the pcie_aspm=force command during boot. There does seem to be some devices I have that don't enable ASPM even with that for me, mostly some usb stuff on my laptop and the Intel wireless 5100 adapter. I don't know that it makes a huge difference, with the Maverick kernel, I can see idle power usage down to 18 watts, but that is all PM options enabled, and nothing running but Unity (by the way, unity is much more power efficient than the older Gnome 2.x - Who would have thought..) with the latest upstream sources from git.kernel.org or the Oneiric sources I can see it idle at about 19-20 watts. Not a lot lost. the other thing to realize is there were many scheduler changes that have been made since 2.6.38 in Natty. Many of them improve things for power utilization. One developer found that there was a problem with counters rolling over that would cause timing issues with load balancing between multiple cores, and it would wake the CPUs early, preventing them from idling in low power states. This is fixed in the upstream sources, and helps a bit with the overall performance. Maybe it is just me, but when I am actually doing something on the laptop, it doesn't seem to run the battery down as bad with the patch in, so maybe that is something. Your experience may vary, some didn't report any issues in this thread at all with natty, some even said they got BETTER life out of the battery on Natty vs others. I think it depends more on how seriously your laptop manufacturer takes BIOS debugging, as many don't try very hard. If you happen to be a lucky person with a good BIOS, like maybe a decent lenovo or something, then you might not see any issues at all. Matthew Garrett was the subject of a recent article on LWN.net that gives a good history on this. Maybe it will help more than my rambling. http://lwn.net/Articles/449448/ Most of the stuff I have read from the Devs make it look like the long term fix is going to be changes in the drivers to override the broken crap even if the BIOS is stupid. But that will take updates to the affected drivers by those who know how, and when it is appropriate to force the override on all users' hardware. Matthew Garett actually mentions this, that perhaps some things work in windows as some drivers already force the handoff of ASPM functions when windows initializes.

There isn't any easy 'solution' to improve this situation beyond affected users forcing the PCI-E Active-State Power Management using the pcie_aspm=force kernel command line option. Jesse thinks that more Linux drivers will end up needing to set the ASPM bits directly as a long-term solution. There's just too many hardware devices that don't properly support the ASPM power-saving modes. The only alternative would be to create a big white-list of supported devices, but that comes down to being effectively the same large task as just having the driver set the appropriate bit. So there won't be any magic fix in the Linux 3.0 kernel nor will there likely be any major change in the Linux 3.1 kernel without suddenly a bunch of drivers handling the Active-State
Re: [Bug 760131] Re: Power consumption raised significantly in natty
well, I woudn't say negativist, but..
I think the power issue is a bit overblown. even in the inital bug report
for this, Natty was like 15 percent more power hungry than the older
versions. And - this is not unique to Natty, or Ubuntu..
if you look around there are bug reports for this exact bug on Fedora,
Debian, I think I even saw this in Gentoo and Arch as well. Most of the
effort I see Ubuntu developers working on are usability and GUI
improvements, and don't discount the work they do to enhance the stock
debian packages to make Ubuntu as stable as possible.
the Power utilization is higher, true, newer kernels do not have as much of
a problem, and there is the option to force the pcie_aspm to work like it
used to, so there is no functionality lost. It is a bit of a cludge, but
you should expect that when running the latest and more bleeding edge stuff.
Before you start assuming that there is a major disconnect with the guys at
ubuntu though, try out the latest Fedora.. notice anything?
Power issues are the same, and they have this fancy new GUI also, only it is
Gnome 3.0 - I'm not saying either one is better, but there are more
similarities than differences that I have found. But lately Gnome has
ticked me off too much - you have LESS options to customize and tune than
Unity or others. I used fedora for maybe a week, reinstalled Natty and have
been happy since.
If you don't like either one, and want something more flexible or whatever,
try the alternatives. KDE is looking really good these days, might be the
prettiest GUI I have ever seen, and now it really seems usable, how funny
that a year ago, everyone was preaching doom and gloom on the changes from
KDE old to KDE new.
I will also say that Ubuntu is one of the more stable and easy to use
distros out there, they don't take away my insatiable desire to tinker with
the guts of it. And I don't see any other OS that is as easy to add other
devices to now. Windows is a pain in the @#$@ to get some new device on
there, what with the installers that HP wants you to use so you can't just
install the damn thing, - I have to also add your bloated replacement for
stuff that windows can already do, and other issues..
Macs might just work, but only if you use their stuff.. A PC would just
work too if I only had maybe 20 or so things I could plug into it..
anyway I have veered way off the subject.. hope I don't sound too
trollish..

I base my opinion on +cjcolella's note:
I do think that not considering battery life as a priority will make

interface and one of Ubuntu's major decisions: it dropped Gnome and made
a whole new interface, Unity, that has one of the main objectives to
make it EASY TO USE on touchscreens.
But most touch screens are on phones, tablets, notebooks, netbooks, and
other mobile devices. I think nowadays, mobile devices are the most
succesful on any markets and I think Ubuntu had a good idea to address the
mobile users; but it's important to make the OS work at least as well as
other OS's.
Why would I use Ubuntu/any other Linux (as it is a kernel feature aka
bug) if my cool device can't be used with it?
Call me negativist, but this is a any-linux-distro-killer issue and
should be shared with other distributions and insist at kernel
developers. This needs a solution ASAP, before users start looking
elsewhere.

Re: [Bug 760131] Re: Power consumption raised significantly in natty
I would offer the opinion that this is more like a regression as this exposed a kernel regression as proper aspm handling requires changes to the drivers in the kernel. In the article, it mentions that the windows drivers may have additional bits for aspm functionality, thus overriding BIOS handover. This is not unlike previous issues seen with linux where many BIOS implementations are usually just good enough to get windows working, specific functions they are supposed to do are not done according to standards. Before this issue there were numerous issues with suspend/resume, DPMI, intel graphics bios missing resolution info, and more. Each issue resulted in hacks to work around until drivers or the kernel got a more permanent fix. On 6/30/11, Jon Grossart 760...@bugs.launchpad.net wrote: While, I agree that this a huge problem overall, I'm think I have to agree with the idea that it's not a regression. If you read the comments on Phoronix from the actual path author (which was only linked on the little side bar of the page, not the main column), he makes the statement a little more clear. http://www.phoronix.com/scan.php?page=news_itempx=OTYwNA The patch enables correct handling of the ASPM to the BIOS if it can handle it, otherwise it lets the kernel do it. However, it then depends on the hardware drivers to setup the correct values. That is the problem that is happening with this bug according to the author. The kernel is now handling the situation correctly, and it is revealing a lot of long standing bugs in a lot/most of the drivers and BIOSes in that they don't handle ASPM correctly, or coded to the fact that the kernel was incorrectly managing it before. Quite frankly, it sounds a lot like the whole IE6 problem plaguing web browsers. Maybe this has something to do with the overall higher power consumption in Ubuntu often seen. On netbook in WinXP I can it down to 5W idling. In Ubuntu with same config, it won't go below 7-8W. The only thing I can think that would make the different is the driver settings/abilities. So what is the correct fix? That, I don't know. BIOS and hardware drivers are real culprits it seems. Chances of BIOS fixes are probably slim for the vast majority of systems.

Re: [Bug 760131] Re: Power consumption raised significantly in natty
Jon- absolutely agree. Only way I can figure this isn't getting more attention is that the majority of datacenters are using enterprise versions of the kernel, which are several versions back and aren't affected yet. Once RHEL version 7 or 8 comes out with 2.6.38 or later, everyone would get a bit concerned when the power utilization goes up. FWIW it probably wouldn't affect really busy servers as much, this seems to really affect power usage when the cpu is lightly loaded or idle. On 6/30/11, Jon Grossart 760...@bugs.launchpad.net wrote: Regression/proper behavior or whatever it ends up being called, there is a lot more fixing that needs to be done. What has surprised me about the whole Linux community is that no one seems to be really all that upset or even tracking the problem as a whole except Phoronix and the users. It would seem with the prevalence of laptops that power consumption would be a huge priority. Although, there are tons more servers than laptop running Linux, so maybe that is the issue here as well.

Re: [Bug 760131] Re: Power consumption raised significantly in natty
I did some digging on the lkml forums (hard to add links from the bby) It looks like all of them relate to a series of commits for the kernel IPI process. It looks to be added as a way to load balance processes accross multiple cores in the fair scheduler (CFS) when the kernel is running tickless (config_no_hz). IPI is supposed to evaluate what core should handle the load balancing process across all cores at any given time, based on which ones are busy and idle. It looks to me to prefer keeping the load balance process on a lightly loaded core so that the heavier processes don't get impacted by the additional work of managing the other cores' processes. It sounds to me that it is a good way to keep high performance in a server (especially as you increase the number of cores in the system,) but I wonder if that may be the wong approach for a smaller system looking to maximize power efficiency instead of raw performance. On a single socket dual core system like atom, brazos, core2duo etc, it doesn't seem to be necessary as the cores on a single socket share cache and other resources. I wonder if it would make more sense in the smaller systems (single socket) to assign the load balancing process on one core, skip the IPI altogether and only wake the other cores when there is work to do. Perhaps even prefer to run new processes itself until it needs to wake another core. (Unfortunately, I am not a kernel hacker - If I am misunderstanding any of this, I would welcome someone to correct me :) On 6/10/11, Julian Kalinowski 760...@bugs.launchpad.net wrote: This is getting OT, but how can you get 1141 wakups/sec when your top wakeup cause has only 33.7 wakeup/s ?

Re: [Bug 760131] Re: Power consumption raised significantly in natty
Cjcolla - with over 1000 wakeups per second, I would not think there is much chance of the processor entering a sleep state at all. It looks to me like all of the wakeups are from your usb devices, were you doing much with the mouse or anything like that while taking the snapshot? Earlier in the thread is a link for 2.6.38.9 kernel patched to fix the kernel wakeup timer wrapping issue, on my laptop it doesn't seem to change the maximum power draw in powertop, but when wakeup events are triggered, the power draw doesn't seem to spike as bad. With desktop effects on and I am running unity with the proprietary nvidia driver, I idle at about 21-22 watts and about 100 wakeups per second. With gnome (no effects). That drops to around 20 watts. Nouveau will kick it up to 26 watts at idle. With the lucid kernel running on natty, I get idle down to about 18 - 19 watts and the nvidia driver. 24 watts with nouveau. You might want to check into installing laptop-mode-tools and verifying you have cpufrequtils installed. My friend's eepc 1015 was upgraded to natty, and did not get those installed by default, I added and enabled those and installed the proprietary fglrx driver to drop him down from 16 watts to about 9 at idle with unity running full effects. I was running conky configured with conky-colors (mentioned at webupd8) and found that the 1 second polling was eating up a lot of power. Top wakeups were from the window manager and the kernel load balancing process. Killing conky dropped both of those down again. I changed conky to only poll every 5 seconds, now the draw isn't too bad, maybe 1-2 watts additional. On 6/9/11, cjcolella 760...@bugs.launchpad.net wrote: @z06gal: Thank you for the suggestion, but unfortunately, 2.6.39.1 shows little improvement on this hardware (Toshiba laptop L305-S5937, Core 2 Duo Intel processors, integrated Intel GM45, etc.).

Disabling desktop effects doesn't change the results much.

Re: [Bug 760131] Re: Power consumption raised significantly in natty
Yes, I noticed. I compiled up a lucid kernel - 2.6.34, runs fine on natty. Strange thing I see is that the ACPI reported power usage is the same on my laptop, about 19 - 21 watts, yet I get 3.5 hours on that kernel instead of the 2.1 hours on the natty kernel or the 2.6.39 source from the linus tree. I'm using the same nvidia blob on both. If I switch to nouveau it increases the power usage noticeably, adds about 4 watts in both cases while running gnome or unity and the xorg edger's mesa and xorg binaries. I don't understand how the ACPI power usage can be the same and still have such a large variance for run time on the battery...

Re: [Bug 760131] Re: Power consumption raised significantly in natty
It might be a cludge, but a workaround might be to disable the tickless kernel option, multiple core systems and hyperthreading would still work with a slight increase in overhead- at least until this has an accepted patch from the kernel folks.

The status says fix released, yet it doesn't appear to be fixed. Does
that mean the fix is coming or does it mean the fix didn't really fix
it?
Thanks for any reply.
