Looks like some member can't read and understand... :( The cached apps decrease the free amount of ram, BUT this part of the ram is ALWAYS available if NEED more free ram for any running active app/process, just drop the cached apps.
Advantages of the less free ram/bigger cached area:
- the cached apps starting faster (the ddr data rate/access time is 100 times faster than the slow nand chips)
-better multitasking
Disadvantages of the more free ram:
- bad multitasking
- the recently used apps start slower (need to reload from nand/sdcard because dropped from cache to get higher free ram)
Typical bugs with too agressive oom/lmk settings:
- lost messages (the message app dropped to get more free ram)
- delayed incoming call/slow dialer (the contacts app dropped)
- delayed keyboard start (keyboard dropped from memory and need to reload on every text input)

Okay, better if we stop this discussion here, lot of threads exists about android ram management.
I just wrote it because recently read posts about the "more free ram is extreme important" ;)

Hi,
Could somebody make this kernel working on gb rom?
Thanks:)
EDIT: I mean modify kernel to gb roms could work on it

Hi nAa this request is asked by me in my SDE thread ,

uploading new version v2.0

Changelog :


for more stability and speed i sugest to all sde users to ask nAa to make GB version of his new kernel with shuld improve a lot the rom speed​


cheers

Achotjan

as i has say in this post we need new kernel for better stability of SDE
if you have somme time , pleas make a GB version with my DRM suport included for SDE users

Thank you

cheers

Hello @nobodyAtall,

We know that you are working in kernel 3.0.x for Xperia 2011 line.

Maybe when you have some free time ( :p ) you can take a look at @
psyke83 work (github) and try to build one for Xperia 2010 line:
Kernel 3.0.x for samsung msm7x27 or other msm7x27 kernels available on androidarmv6
[DEV] CyanogenMod 10.1 Galaxy5 Port [androidarmv6] or [DEV] CyanogenMod 10.1 Galaxy5 Port [androidarmv6]



Thanks

PS: I am just a fan of your work and missed you in Xperia 2010 forums! ;)

You can make it... Only need to make diff with nAa's 2.6.32.60 kernel github's first commit and official 2.6.32.9 kernel commit... You can see how what changed... that changes needed on any other kernel... I'm sure it will work...

MW600 in this Kernel

Has anyone managed to use a headset bluetooth or MW600 in this Kernel?

Thanks

    If you brick your device, you are the sole responsible.



    Preface:
    • Read through this post. Don't rush into flashing. Be sure you understand the process before you start or you risk damaging your device
    • This is a custom 2.6.32 kernel developed for Android Jellybean 4.x. However, as of nAa-06 Android gingerbread is also supported. This kernel only works for shakira, a.k.a. X8,W8
    • Do NOT try this kernel on other Android versions or phones - you are totally unsupported
    • This kernel uses a custom mtd partitioning with larger /system partition to hold the extra JB calories. If you are moving from another custom kernel, EXCEPT 2.6.29-nAa-jb to this one, you MUST first format /system /data and /cache via the embedded CWM recovery
      [*] If you want to flash another kernel after having flashed this one, you MUST first format /system /data and /cache via the embedded CWM recovery

    FAQ:
    If you have any issues, please read the FAQ thread first: TODO

    Requirements:

    Install:

    Uninstall:
    • Flash back to stock using SEUS

      OR

      [*] Format /system /data and /cache via CWM and THEN flash another kernel via Flashtool

      Any other way is completely unsupported, don't ask how to unbrick if you can't read the instructions

    Notes:

    Dualtouch (for synaptics):
    By default dual touch is disabled for improved touch accuracy and avoidance of the 'ghost touch' side-effect.
    • If you want to enable the fake DT by andrej456, you have to insert the following line in the /system/etc/hw_config.sh file:
      echo "1" > /sys/module/synaptics_i2c_rmi4/parameters/cfg_dt
    • If you want to enable the fake DT by dx, you have to insert the following line in the /system/etc/hw_config.sh file:
      insmod /system/lib/modules/synaptics_i2c_rmi4_dt.ko
    Dualtouch (for cypress):
    Cypress supports dualtouch, so this is enabled by default

    Sources:
    • The linux kernel is GPL'ed, everyone who does modifications should make them publicly available.
    • Making a kernel thread for posting a difference in the ramdisk or for a so-called 'improved governor / io scheduler' is legal, but plain stupid, disrespectful and wasteful
    • I accept patches any way possible. Basically I only read pms if they contain some suggestion or patch ;) Credits go to the author obviously

    If you are enjoying my work please consider donating:
    Donations are voluntary but allow me to spend more time on this project.

    I can't be held responsible if this Kernel bricks your device or makes it explode in your hands! Use it at your own risk!

    Hello community,

    I've decided to work on one more version of this kernel that will be supporting gb too.

    -- nAa

    VDD levels

    From 03 onwards, I've ported the vddlevels functionality from msm7x30 so that we can variably change the voltage level of the frequency we want without the need for external modules.
    The current voltage information is available at:
    /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

    E.g. the defaults after flashing the kernel should be:
    root@android:/ # cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
    122880: 3
    245760: 4
    320000: 5
    480000: 6
    604800: 7
    614400: 7
    633600: 7
    652800: 7
    672000: 7
    691200: 7
    710400: 7
    729600: 7
    748800: 7
    768000: 7
    787200: 7
    806400: 7
    825600: 7
    844800: 7
    864000: 7

    To change for example the voltage level of the 122880 frequency, you could do:

    echo '122880 0' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

    If you cat this file again, you should see that the voltage level is picked up. The new voltage level is picked up when the CPU will scale to the particular frequency level.

    The undervolting tickbox in the 'Performance Settings' of the latest MiniCM10 nightlies already uses the new interface. The values that are set there are the same ones as those passed by the old undervolting module:

    root@android:/ # cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
    122880: 0
    245760: 2
    320000: 3
    480000: 5
    604800: 6
    614400: 7
    633600: 7
    652800: 7
    672000: 7
    691200: 7
    710400: 7
    729600: 7
    748800: 7
    768000: 7
    787200: 7
    806400: 7
    825600: 7
    844800: 7
    864000: 7

    Do I need undervolting?
    You dont NEED undervolting. It can save though hours of some battery life during the day.

    Overvolting?
    Even though the interface allows you to overvolt, I don't suggest doing so. It will result to instabilities or crashes and is totally unsupported.

    Performance?
    Undervolting decreases the performance results - this is to be expected.


    Performance comparison vs .29 kernel
    +20%-30%

    Hello community,

    nAa-06 is released today. The changelog list is short, but significant.

    2.6.32.61-nAa-06:
    - Supported android versions: gingerbread, ICS (not fully tested) and JB
    - Linux 2.6.32.61
    - Various ramdisk improvements

    For gingerbread, please flash it with MiniCM7-2.2.2 since some rom changes are also needed.

    Enjoy!
