    that's a good question...


    it requires reformatting the /system, /data, and /cache partitions to ext4.


    but there's not a tool to do that for these phones "yet" that i know of.


    i just added the capability for the future of the device but my next project is writing/modding some scripts to do this formatting that way we all can enjoy what's in this new kernel.
     
  4. okay how about mount2sd? it has a setting of switching ext and data but ive been trying to get the sd portion to get recognized but ive had no lick what so ever

    i think you're confused...

    mount2sd has nothing to do with this kernel or formatting your partitions. that's for mounting apps and their data to your sdcard.

    the kernel supporting ext4 is to support your filesystem, ie. all your data partitions--cache, (dev--if it's used for dalvik-cache like i do), data, and system--being formatted to ext4.

    i can actually make the kernel support many filesystem types with the click of a button. i was experimenting with the secure fs system but i ran into some troubles and just decided to stick with this for now.

    I think the Merit on ext4 over YAFFS will show a decent improvement in it's responsiveness, especially combined with an OC kernel.
     

  7. oh okay then yes you are right i was confused. i was thinking that had something to with portioning the sd card with ext4 ive been trying to install ubuntu on the phone so i need an ext4 on the sdcard to be recongnized but i think i would need a kernel that supports loop and an ext

    actually, in the end i think you were right to begin with.

    this kernel will support ext4 for sd-ext partitions and loopback (as far as i know).

    mtd is incompatible with conventional file system types such as vfat, ext2, 3, 4, ntfs, etc. there is no way to format such partitions to ext so the capabilities in the kernel are strictly for the sdcard after all--and more beneficial for devices that have an internal sdcard.

    mtd can't become an ext partition. period. so in the end building this kernel for such purposes has been useless.

    but this isn't surprising because of all the misinformation that is spread all over the net about android developing by people who don't know what they're doing. it's not the first time i've experienced proving conventional android wisdom wrong lol

    but at least we got an overclock kernel (with more on the way)
     

  9. i agree thanks for the kernel. is there a way you can set the overclock higher? or figure out about that mtd thing lol i wish i could work on the phone myself but i have no computer thats why i want to install ubuntu on the phone so i can at least try to some development too and again tanks for the kernel btw i got your recovery installed too ;-) youve done a great job

    It was put to the test in a roamer with SFe-v1.0. For now, everything is working. Final impressions I will share with you the other day when we test the little better.
    Antutu with Anthony kernel 935 - with your 1184.

    :thinking: I hit 1400 on bare bones (no apps) at 600mhz... I even have a snapshot to show it.

    This was when I was assembling AreaROM 1.1, before my Avail died.

    your snapshot clearly says 600mhz, not 1.4ghz

    1406 is your score--add everything before the 600mhz on that screen and you'll get 1406. your cpu was never running higher than 600 when it was tested

    my phone scored a 3226 without the oc kernel...

    Nice score, but you did just repeat what I had said. I stated that it was at stock speeds, referring to zajchiks results. Also, I pulled that test before antutu's update to 3.0, which skewed my results by almost 1000 points.

    kernel updated

    now stable and the screen lockout glitch fixed.

    sadly, had to cut down the overclock to keep the gpu from freaking out and refusing to resume from sleep.

    this works fine with my ROM. I used it for a little bit, and might package it in my next update.

    a kernel is a kernel--has no effect on the filesystem

    edited .rc files within a boot.img can have an effect on the filesystem

    however mine does not

    therefore it should work just fine with most any rom

    Hey boogy, gotta say I'm impressed. Been looking at some of your GitHub work, and looks like you have a pretty good idea of what's going on. ;-)

    I put Phydeaux ROM on my phone many months ago, but really missed the OC feature that SpeedFreak offered, so I was glad to see your kernel here.

    I went ahead and installed it, and everything seemed to be fine. But, I lost all my SD card swap stuff, so I did a restore for now until I get time to get it all working with your kernel.

    Is this kernel on your GitHub area? I didn't see it, unless it's under a different name. I'm getting more and more into learning the true OS aspects of Android, and would like to start developing some day, so I just wanted to get some good pointers from someone that has your experience.

    Thanks for all the hard work! The results show. :)

    my github is out of date for this device.

    and no, i haven't posted the overclock source. mainly because they are some flaws in it that i haven't fixed yet. the device really can't handle any more than this though. at 7.9+mhz there is a wake from sleep bug that i can't seem to fix. it has to do with the freq wake lock in the kernel, i just haven't really wanted to work on it.

    i can give you some pointers if you need them, just pm me sometime.

    thanks for the kind words

    There are more important builds going anyways ;).

    Understood. I really like this phone, but starting to get to the limit of its capabilities for being able to use it as a tool, instead of a showpiece like most peeps use their phones for. :D

    And thanks for the offer. I'm sure I'll be taking you up on that.

    Would you mind uploading this much needed file to another downloadable location. I'm using the newest dolphin browser and it's not being very mediafire friendly. Thanks in advance SB! :)
