GNM_TURBO JIT + OC = 8+ mflops

    ATTN this is outdated and not compatible with froyo!!!!!!!!!!!

    First of all I'd like to state the amount of time/work I've put into this project for a device that I don't own. I have spent probably 50+ hours into developing stuff for the LG Ally not to mention even making custom roms a possibility for your device. To develop this I had to create a patch to optimize the davlikvm and many's for the ARM Version 6 code the Ally's processor runs as this is not included in android source. I also figured out how to enable jit compiler on eclair and also in the javascript in the browser with I also developed a patch to overclock the msm7627 processor up to 787mhz. LG made things very hard by having a proprietary memory allocation on their's that the only other device that I found that shares the same map is the acer liquid.

    OK on to the fun stuff:

    Ally stock gets between high 3's to max 4.2 MFLOPS. Overclocked alone we got it to 5.2 MFLOPS. With only jit its 6.9 MFLOPS or so. With jit and overclock we have hit 9.1 MFLOPS. To put that in perspective the droid x on on 2.1 only hits mid 7's with a 1 ghz ARM v7 processor. Thats how much this will turbocharge your Ally.

    Included in the flashable zip:

    ArmV6 optimized dalvikvm and associated's that enable jit.
    Jit enabled
    Overclocked kernel with 729, 748, 768, 787 freq.

    All of the above are compiled from source.

    How to install:

    1. From a custom recovery wipe your dalvik cache & cache.

    2. Flash zip over your current eclair rom.

    3. Reboot and enjoy!!

    Notes on kernel:

    Max speed on kernel is set to 600mhz on boot for safety. To clock it higher you must use setcpu and reapply the setting after every boot. If it shows 600 as max but slider is above 600mhz you need to just move the sliders to reset. Not everyones phone will be able to run overclocked due to the QA on their processor. Some can run up to 787mhz while some can only run 748mhz etc and some will only do 600mhz. Every phone is unique so find the speed that works for you. Again this is not a defective kernel it is unique to YOUR phone. If you don't want to overclock dont use setcpu and it will run as stock. Also, ext 3 & 4 filesystem support is included in kernel.
    Use autodetect for setcpu too.

    Ok before downloading I'd like to say your donations will help me get an ally to help dev on and a better FTP server. For the 2k+ downloads on my recovery I've gotten a grand total of $0. Hopefully some of you will see the effort I've put into this and toss a little bit my way.

    This package is not to be hotlinked or mirrored please. Please direct to this thread as it will have the most up to date info.

    Special thanks to:

    Vmanisme & Trident for testng

    Change Log:

    Added overclocked kernel and no kernel versions.
    Fixed Calculator.apk - rebuilt from source.
    Signed zip properly this time

    Have you tried this on the new Velocity 0.2 ROM?

    No. Not yet. i will when i get home.

    what about you @drellisdee?

    I've just tried it velocity v0.2. It re-enabled the verizon boot animation. Also the red-eye seems bigger? (can someone else confirm this?) Was a bit slugglish a first but after a couple of minutes its working flawlessly.

    Sweet! Will be apply today over my Velocity rom Thanks dots!

    @drellisdee, i am willing to begin testing for you, if you would like.

    do you mind if i host on my server so you have a second mirror?

    Just flashed this and all seems to be well. (Flashed onto Velocity 0.2) Now trying to figure out how to use setcpu correctly to OC this thing... I will keep posted. =) Thanks Vman and everybody else whohave developed these tools. As soon as I get paid you will have a nice donation in your PayPal account drellisdee!!

    This is soo awesome dude! Just finished figuring out SetCPU etc. and now my Ally is running at a nice 787Mhz! Your donation size just went up... =) Wait a couple more weeks and you will definitely have a generous donation from me!

    I have the stock boot animation in boot.img. Also, sometime it takes a little bit for a phone to adjust to a new kernel.

    Thanks for all your hard work man I will be making a donation later this week. Will being installing this later today to check it out.

    Just to be clear, this can be done on top of Velocity 0.2? I don't need to go back to a stock rom or anything before doing it?
  12. flick159

    flick159 Well-Known Member

    Yes, just did it over top Velocity 0.2. Works extremely well!
  13. getitnowmarketing

    getitnowmarketing Well-Known Member Developer

    Correct any rom thats 2.1 Eclair based. Stock or custom doesn't matter. Making a nandroid backup is always recommended before flashing anything though.

    Post your linpack scores guys!!! Before & after would be great.

    Before, upper 5ish on a 748 OC on Velocity 0.2

    With your JIT compiler and a 748 OC I'm getting low 8's

    Really really awesome. Great work man! When I get paid again I will gladly make a donation for all your hard work. You've been pivotal in the development of this phone.

    My first benchmark with my Ally OC'd to 787Mhz yielded 8.087 mFlops in Linpack. I'm a very happy person! =)

    Before oc i was in the mid 3s now im just did 8.164! thank you so much for all the hard work and time you have given us, I will be donating as soon as i get paid again, and if you ever need any help or a tester just hit me up.

    Hey all. Going to to try this later tonight, but I have a couple of stupid questions first.

    1. The OP says to wipe cache and dalvik cache, but doesn't mention data. I assume that's intentional but just want to be sure. We don't have to wipe data? Just the cache and dalvik cache?

    2. It says to flash over the current ROM. Is there any procedural difference between flashing over an existing ROM and flashing a full ROM? Or do I just use the same "Flash ZIP from sdcard" option from drellisdee's recovery.

    3. Does this have much impact on battery life? I assume that overclocking will reduce battery life somewhat, but will leaving it at the stock setting keep battery life about the same?

  19. MikeyV311

    Its really easy man... just open up rom manager and choose flash rom from sdcard (or wherever u have the file). Then just go about flashing like u would with any ROM u have flashed. Make sure to check the boxes that say backup existing rom and clear data cache etc. Your phone will reboot andthen its up to you to overclock the cpu with setcpu. For device type in setcpu make sure to choose a phone that is using ARM as a processor. This is what I. Just did about 2 hours ago and my phone is running great at 787mhz!
  20. MikeyV311

    MikeyV311 Member

    Oh yeah forgot to mention battery use. So far it hasn't been overly bad at all and I've been running 787mhz for about 2hrs now. Also I don't notice any extra heat yet from the phone. Setting the cpu back to stock clock speed will indeed use the same amount as a stock rom. Actually probably less bc velocity is so awesome!

    will this work with the root update patch ZVB?

    if i click wipe data and cache in clockwork, does that wipe the dalvik cache, or no.
  24. dots

    dots Well-Known Member

    Do not wipte data.

    You should boot into the recovery to do this.

    Only wipe cache and dalvik cache. To wipe dalvik cache in clockwork go to advanced and you should see that option.

    nevermind question just got answered while i was posting

    I swear Rom Manager hates me. I tell it to backup current Rom, phone restarts and hangs at LG screen. Ok screw it I don't need a backup I'll just load a rom from scratch if I need to, so I tell Rom Manager to reboot into recovery so I can just flash this, again hangs at LG screen. Had these same sort of issues when I was originally flashing Velocity 0.2. What am I doing wrong?
