    rMoD Series Kernels for the Original Droid Only

    With SmartMoD governor!

    These kernels are based on RaidZero's source code, big thanks to him for sharing and saving me some time, effort, and headache!

    Default governeor is set to interactive, I highly recommend switching to SmartMoD, battery life is much better and speed stays the same :)

    Testers have reported nice temps even with high clock speeds :)

    SmartMoD governor is a modified governor originally made for the hero, I modified the governor to perform better with our cpu. You can find some information on the original governor here.

    What SmartMoD does, when your phone is in use, screen on, the governor will behave much like the interactive governor, but when you turn the screen off it holds the max clock speed to 350, as soon as the screen is turned on the governor jumps to 900 (or max if you're running a lower speed kernel) then resumes acting like the interactive governor.

    Now at this time I'm releasing what I have built and what I know works, as always make a backup before installing these. Take responsibilities for your actions, I provide these kernels with no promises, if you want to use them do so at your own risk. DroidForums and I will take no responsibility for your use of these overclocked kernels.

    I will be adding more as I get them done and know they work well so please be patient with me.

    This is a new set of kernels I have been working on for the Original Droid ONLY

    SmartMoD governor again with more tweaks for better responsiveness

    I spent many hours building, flashing, and testing these kernels in order to achieve the lowest possible voltage my Droid would function on on each of the different clock speeds.

    According to Petes table listing some of the popular kernels voltage settings mine rank in the lowest on most of the differnet clock speeds.
    Pete's tables

    Here is an example from my 1100
    Code:
    My 1100            Avg according to Petes research
    ***********************************************************
    250   27                  33.2
    500   37                  47.4
    700   43                  54.4
    800   47                  59
    900   53                  62.4
    1000  60                 68
    1100  69                 72.4
    
    My 1200 is right on (due to my Droid not liking high clock speeds :) and my 1250 is a little lower)
    I tested every kernel except for the 1250, I have yet to get a 1250 to boot on my phone, but davros was kind enough to test it out and has reported it working.

    These are low volt kernels, they may not work on your device, if one doesnt work try a lower speed kernel. If none of them work check out my other kernels here

    Disclaimer!
    DroidForums and myself are not responsible for any damages caused by these, you are modifying your phones factory software. Use at your own risk!

    Warning
    These are very low voltage kernels, your phone may not function properly or my not even boot using these. Please make sure you have a backup before installing! If you have issues with these try the kernels in the post above, they will be more stable!

    Thanks for the great kernel. Compcache is working and the SmartMod governor seems like a cool idea. Unfortunately I can not get Link2SD to work with my ext3 partition using this kernel. I had it working previously with prime's deprimed kernel. I cleared out all of the old modules before installing and I see that your kernel installed an ext3.ko module but in link2sd it says "Mount script cannot be created mount: No such device ext3 may not be supported on your device."
    Is there something I need to do to get the ext3 module to load with this kernel?

    Also I tried to start the ext3 module with terminal emulator by typing:

    insmod /system/lib/modules/ext3.ko

    but I get an error message:
    insmod: init_module 'system/lib/modules/ext3.ko' failed (no such file or directory)

    However I can see ext3.ko in the modules folder if I browse to it with root explorer. Any ideas?


    Thanks in advance for any help.

    Loaded up the 250-1200 kernels on several different roms and they are working extremely well. Very smooth and blazing fast. Thank you very much!

    Not sure what the problem is, I tried and get your same error. I don't use ext3 so didnt think to test :blink:

    I will try to figure out the issue, thanks for reportig :)

    On a side note, I have the kinks worked out so I can now build these with SmartMoD as default gov! Updates will be posted when I get the time to sit down and rebuild all of them.

    Also for those of you a little more daring, my source is now on github. The same source was used to build both of these just used different voltage levels.

    enjoy!

    ^Only CM7/UD3 use zram so it may or may not not be worth your effort.

    No problem, thanks for checking it out. The smartmod gov is a really cool idea and I'd love to have it working but I need my ext3 as I'm an app hoarder lol.

    I know I asked u this before, any chance you will be releasing any kernels (1ghz would be nice) with complete data collection enabled, specifically "time in state" stats? I find that usefull info to monitor what ur ph is doing at any given time, especially if things are behaving when ur phone is "sleeping".

    I have wondered in the past & inquired about it before, but no one seems to know for sure, but does having that enabled affect (positively or negatively) battery life at all?

    I'm trying to find a fix for this, I got it to work on a 600mhz kernel but the same setup moved to 800 & up fails.

    Anything on your phone that does something is going to affect battery life...that's not saying it will be a major change & I doubt it would be noticeable

    I am going to be starting a new project from aosp so i know what all modifications were made to the source & will be easier for me to fix problems

    Please keep in mind I'm a father of 2 & work road construction, I'm laid off right now but should be going back to work soon...also getting married in june, life is pretty busy so it may take me a while

    hey CorCor...have you looked at Prime's kernel with the governor bumblebee? its interactive and smartass just like your smartmod.I'm curious about the differences...he says he has a lot of Droid specific stuff that I know nothing about...anyways...I'm loving your kernels but the low volt were tooooo low...I'm currently running primes to see how low I can go.

    I didn't know he had added it to his kernel yet, but a quick look at his thread tells me his bumblebee governor is the same as SmartMoD but probably with his own tweaks. I see his source code isn't available so I couldn't tell you the differences. If you are curious about my settings you can find them here https://github.com/corcor67/rMoD-sholes-omap/blob/master/drivers/cpufreq/cpufreq_smartass.c

    Yes the juiced kernels took lots of work, they are quite a bit lower than other low volt kernels on many of the slots...each slot was tweaked one at a time for all the different clock speeds to find the lowest I could take them on my phone...some peoples phones would be able to handle lower and others won't be able to handle that low

    Hope this helps with some of your questions

    WOW! Amazing battery life, probably the best I've ever gotten. I use my phone a LOT throughout a normal day. I'm using the 250-1100 SV, throttled down to 900.

    I'm usually swapping out my battery for my backup around lunch time, I just now hit the 15% warning. So an additional 3-4 hours added to my normal routine is very much appreciated.

    Haven't really noticed a difference in performance, maybe a little slower than the P3 kernels I was using before, but the battery life more than makes up for anything else.
