    This is really exciting stuff. So the Govnah app won't work with the new "Super PreKernal" that was released, correct? Bummer. Installed it and wasn't getting anything to work.

    Edit: Answered my own question, nevermind.

    Yes, they're included, though I haven't tried either myself.

    Does govnah run in the background, or does the application have to remain running?
  4. #24  
    When I first ran Govnah (about 2 hrs ago) it said 41. It stayed there until I re-ran Govnah and it ticked up to 42 where it has stayed ever since.

    Two questions:
    1. Reiterate todivefor's question: does govnah need to have a card active in order to update? Or will it update w/out an active card?
    2. What are the threshold temps that should cause me to be concerned?

    As per the webosinternals twitter feed last night, I believe they're trying to still figure out a range of normal temperatures for the device.

    is govnah supposed to be blank? I don't see my current governor, or any options to change it.

    LOL, All it does so far, is update the icon when you launch it. Nothing else.

    working flawlessly for me =0) great work !

    I didn't even expect such a public phase for another couple of weeks. Expectations exceeded as usual, Rod & Co.

    Looking forward to trying this when it breaks out of testing!

    Actually, my understanding is that unixpsycho was the sole coder and kernel builder for the actual kernel binary that you are referring to (as opposed to the packaging, marketing, video production, and herculian support of the multiple packaging methods that single kernel binary has been used for without change in the last couple of months).

    The kernel binary used in the package you are referring to reports itself as:

    Linux version 2.6.24-palm-joplin-3430 (beta@web1.xssnet.com) (gcc version 4.2.1 (CodeSourcery Sourcery G++ Lite 2007q3-51)) #9 Wed Mar 17 23:05:35 EDT 2010

    which means it is the original webOS 1.4.0 kernel that Marco did back in early March, and has not been updated since.

    unixpsycho is the main developer of the Uber-Kernel overclocking features, and is contributing other features to the Uber-Kernel too. There are four other kernel developers contributing to the Uber-Kernel too.

    • this one is fully open - meaning that instructions to build, and build requirements are available to anyone with the skill - e.g. it meets the 7 requirements laid out here.
    • this one has the actual CPU temp sensors available as opposed to only the battery sensors
    • this one has more governors than just userspace and ondemand. conservative was mentioned. Are the rest (powersave & performance) included?

    Is there anything else?
    That is all correct.

    Been running the Uber-Kernel all day with CPU scaler ultimate, set at 250-800 OnDemand. Running solid, no issues. Thanks!

    Edit: when I was running the 800Mhz Kernel, it more or less resolved "too many cards" errors when launching 3D games. Will this Kernel provide the same benefit when running at 800Mhz?

    I tried conservative at 125-800 and couldn't stand it. it would take scrolling through several pages of any list before it would stop being choppy (~500 mhz). I think ondemand with a slightly higher up_threshold might be the way to go.

    It's great to see this community involvement in determining the best governor parameters. We'll take the consensus and make it available in Govnah as preset options (in addition to allowing the full range of experimentation using the Govnah UI).

    Okay, I'll bite. Got them both installed, running the "conservative" governor now. Though 250MHz seemed choppy at times, so I put the minimum speed at 500. My phone mostly sits on its Touchstone in my office all day, so I'm not too worried about the battery life.

    Oh, what exciting times to be a Pre owner.

    But really, when has it NOT been an exciting time to be a Pre owner?

    Yeah, it definitely takes longer to get up to speed with the conservative governor, that's for sure. But at the same time, it's also much better about keeping the CPU at the lower state when idle.

    my current time_in_state file:

    800000 34763
    720000 25428
    600000 55483
    550000 65106
    500000 158176
    250000 1123191
    125000 2932244

    I'm going to try tomorrow at 250-800MHz on conservative, see if it's not so slow to get going that way.

    in limited testing so far this kernel does not sem to like smartreflex. I kept getting locks until I was able ti get in and disable sr.

    it screams at 800mhz!

    1. Can this IPKG version install without having previously installed a custom kernel? - Tested, and yes using preware / testing feed.

    2. (Roughly) How long until we see some control functions in Govnah?

    3. Govnah requires running at all times to stay monitoring, or does it do some of it's magic in the background? - Seems it requires to be in a card to monitor. (love the graph of temp)

    4. GREAT job so far, love everything you guys have done for the palm pre!

    Mechanism vs Policy.

    The uber-kernel provides the mechanism to use any supported frequency and any supported governor (not just the ondemand governor).

    Policy is set by the service or Govnah app (or by command line for experimenters).

    Experimenters need the full range of mechanism available so they can converge on a suitable policy which can then be deployed to the public in the service or Govnah app (or any other service/app for that matter).

    Since the kernel defaults to stock speeds and governor, allowing maximum flexibility is not a problem.

    1. Uber-Kernel requires pristine kernel files before it will install. It will refuse to install (without touching any files) if that prerequisite is not met. This is a completely new development, not a revision of any other packaging or previous kernel.

    2. I would expect within a few weeks, maybe earlier if we get lots of free time.

    3. At the moment it is only active when it is running, that will change in the future to allow background monitoring.

    4. Thanks. We're concentrating on monitoring first, raw control second, and then policy (including auto-descaling based on temperature) third.

    Govnah 0.0.6 now has graphing and updating while the app is open (either active or minimised).



    We are not making any statement about threshold temps at this time, because we have not started alpha testing of anything other than stock speeds and temperature monitoring of stock speeds.
