Question regarding the SDcard Speed Fix;

I don't think I need to add the fix every time I flash a new kernel but what about a new CM nightly? Will the fix be removed?

Thanks

I'm pretty sure if you don't wipe you won't lose it, but I always wipe. You can always use file explorer to check in "/etc/init.d/" for the script that is placed there by the sd speed fix you flashed as well.

I can't see a difference in the script? Still slow with a class 10 sdhc card.. around 5mb/s. Will the script automatically be enabled when i just restart the phone?

the script changes the read ahead buffer size. so this has only influence on read. but do not expect wonders. the most you may expect is around 10-20% and thus you may fail observing this during small tests due to stochastic variation

The audio won't pop with 2.5 either on runny O.O
Seems to sound better though with the new amp driver

MIUI doesn't have some new stuff that new nightlies have regarding libaudio, that's why you can use MIUI kernel

Thank you so much dude. I'm just getting my head around cm7 and so far im really loving it.

As you can see by my sig i have been a sense guy. But the past 3 weeks i have been using cm7. I don't think I'll have the bottle to go back to sense tbh. :p

he tested one thing for me, not for public..
other tester say that 3.0b1 and b2oldsense still have popping sound... he uses coredroid... AAAHHH

edit:
@AtypicalWinter
also before flashing you could open 7.5 zip and 7.5 miui zip, and copy over libsqlite.so from CM to miui kernel and than flash to CM ...

    AOSP.jpg




    10029507.jpg







    Kernel taken from official Cyanogen git that is released in in new CM7...
    Benefits over my HD kernel should be (NOT WILL BE) are faster, smoother and less battery draining kernel because of the official DHD drivers for 2.6.35 base and not some ported drivers from other 2.6.35 HTC devices...

    This is all long done :) :
    This is beta regarding patches for speed, smoothnes and battery, but everything else works. Wlan, camera, audio, video etc... At least for me.
    I hope we will develope this kernel together..
    Still misses some crucial patches like V(r) scheduler, VDD interface etc... this is first public release



    Kernel:
    • Based on official HTC 2.6.35.10 source reworked by cyanogen team
    • BFQ v2.1 data I/O scheduler
    • Patched to 2.6.35.13
    • Lots of little patches and tweaks that were previously needed to be added manualy
    • vvvvvvvvvvvv
    • Added audio volume boost up to 22% on main speaker
    • Added Battery fix
    • Overclock to 2 GHz
    • CPU freq going from 122MHz (230 default) to 1920MHz (1152 default)
    • Default UV with maximum stability
    • Allocated more GPU memory
    • SLQB memory allocator added and set as default
    • Patched libsqlite.so to disable db loops - credit goes to ownhere
    • Enabled TinyRCU Bloatwatch edition v8 by default
    • Hopefully compatible with all AOSP ROMS for DHD - CM7 all bases, MIUI, UltimateDroid...
    • V(r) I/O data scheduler as default
    • VDD interface for using UV scripts (by -snq)
    • Tweaked read/write video buffer
    • 2 way voice recording (don't forget to set settings in Call Recording app, MIUI users enable 3rd apps in your MIUI dialer)
    • Proximity Recalibrator 1.6 ready - thread
    • Lowered WiFi voltage (Ziggy741)
    • Added BFS V404 task scheduler as default
    • Jhash speedtweak
    • Ported more than 70 patches from 2.6.38 base
    • added brazilianwax governor, more agressive version of smartass governor based on new version
    • USB Speed hack - from CodeAurora
    • New governors InteractiveX and OndemandX - credits goes to Imoseyon
    • Ported a lot of code and drivers from 2.6.36.1 and 3.0rc6 kernel - credits goes to Imoseyon
    • I/O schedulers are changeable via No-Frills (who uses it)
    • Longer battery overcharging after it reaches 100% than stock (not dangerous)
    • fixed strobe light while Death Ray mode enabled
    • Wifi driver from 3.0rc7 kernel included
    • Preemped Tiny RCU as default with many, many tweaks
    • Autogroup Scheduling added
    • Block code from kernel 3.0 backported
    • XZ comppresed kernel image
    • Compiled with Linaro gcc 4.6.2 (2011.10)
    • Kernel patched to 2.6.35.14
    • Hardcoded float for ARM CPUs (now it uses hardware accalerated float calculation)
    • Cleancache
    • Jhash3 speed tweak
    • Kineto gan ready
    • added FAST charging while connectied via USB or cheap Chinese chargers - thanks to Unity Team and seo
    • a lot of other features
    • added Smartass V2


    Download section:

    Cyanogen kernels: http://blackice.omca.co.uk/download/icecoldsandwich/UE-ginger-kernels

    MIUI kernels: Download normal version, open zip (do not extract), delete libsqlite.so file from system/lib folder, close zip and flash

    CallRecorder 1.0.27 alpha5 for download here

    ​



    TO EVERYONE!
    If you do a full wipe, you must first flash a ROM, than do a first boot with stock kernel! After that you can flash my kernel with any script you want.


    Added flappjaxxx's UV script package with alienmind's LorDmodUV application for easier scripts manipulation with terminal commands in second post!!


    Use Proximity Recalibrator 1.6 from this thread and minimum nightly 92 for the recalibrator to work​

    If you want SD card speed patch, put this file into /etc/init.d folder and give it executable perrmision. It can corrupt your SD data! CAUTION - BACKUP


    AGAIN - don't FORGET to do a nandroid backup prior to flashing!

    git

    Kernel name explanation for NOOBS:
    • 2WCR - Two Way Call Recording support - now you can record incoming and outgoing calls - thanx to avs333 and skvalex for this thread
    • BFS - Brain **** Scheduler is a task scheduler - major performance increase over stock CFS (Completely Fair Scheduler)
    • VIO - V(r) Input/Output scheduler - controls data input and output (memory card, disk, etc..) - stock kernel has CFQ
    • SLQB - a low level memory allocator/manager - stock kernel has SLAB
    • MIUI - kernel for MIUI ROM
    • AOSP - Android Open Source Project - so don't rlash this on SENSE based roms


    Don't replace Vio with BFS.. Completly 2 different things.. kernels come by default with Vio Input/Output scheduler and now also with BFS task scheduler (before was CFS as default in most of kernels)


    Difference between BFS and CFS - link
    This article is rather old....​

    Governors for NOOBS:
    • interactive - Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle. When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.
    • smartass - Is an improved version of interactive governor
    • ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
    • conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
    • performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
    • powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
    • userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
    • brazilianwax - Very agresive version of smartass
    • interactiveX - Tweaked Interactive governor by Imoseyon by adding more features like suspend/wake profile
    • ondemandX - Tweaked and ported from 2.6.38 base Ondemand governor by Imoseyon by adding more features like suspend/wake profile

    KERNEL UV PACKAGE BY flappjaxxx and alienmind:

    This is a full package of all of the undervolt scripts available for the LordModUE Kernel.
    It contains -25mV, -50mV, Ultra Undervolt, Pinky Undervolt & Stable Pinky Undervolt by killersloth all activated and deactivated with the LorDmodUV application

    It also contains a reset.zip for those that can't boot after undervolting located in /sdcard/resetuv
    There is also a README.txt for Usage and instructions also in /sdcard/resetuv

    Just flash from recovery & reboot

    Hi to all,

    As Electronic Engineer, I want to carify and correct some misunderstandings expressed sometimes in this subject, especially concerning the undervolting rage.

    The only interest of undervolting is to reduce the battery drain. But as I already explained, the effect is very limited. Indeed, the power consumption of your phone is governed by several factors, and only one of then is the cpu whose consumption is modelized with this formula:

    P= K x F x V²​
    Where:
    • P= Power [W] consumption (battery drain due to cpu)
    • F= working frequency of the cpu [Hz]
    • V= supply voltage of the cpu [volt]
    • K= a constant depending of the processor and the technology
    As we can easily understand is that reducing the frequency by a factor 2, will also reduce the battery drain OF THE CPU by a factor 2, but reducing the voltage from -50mV (i.e. from 1000mV to 950mV= -5%), will only reduce the power consumption OF THE CPU by only ~-10% ! AT THE RISK OF INSTABILITIES as experienced by some members.
    Moreover, the min voltage acceptable by a processor is also depending of the temperature, so, if your undervolting scheme is working one day, you have a high risk to face instabilities (blocking, auto reboot,....) on another day....fortunately, it is not dangerous for your phone.

    But as said above, the cpu is not the only battery drainer: the most important one when your screen is ON, is....the screen !! Thus, if you want to reduce drastically your power consumption when your screen is ON, is the reduce the luminosity to the min acceptable. Obviously, undervolting cannot reduce the battery drain of your screen!!

    Another factor to take into account is the average daily usage of the phone, and for majority of us, the major usage of our phone is....standby (=screen OFF). So, optimization of this state is probably the most important !! For example, tuning the screen OFF state at lowest possible frequency (122MHz in my case) is more effective than reducing the voltage by -25mV but staying at 245MHz.

    Concerning the other power drainers of your phone, there is the radio, that, if misconfigured, can also drain a lot: the alignment of the latest radio with the (G or HM) Ril can generally solve the problem, but it has to be carefully tested because it can be operator dependent.
    In order to reduce wifi consumption, in /system/build.prop, I set the scan interval at 100 sec (in place of 15sec by default).

    The last point concerns the governors: after making a lot of test between "smartass" and "on demand" for both aspects: perf. and battery drain, I must confess that the differences are for me quite minimal with a slight personal preference for "on demand".
    My perfered settings with Setcpu are:
    - screen ON =122-1382 on demand
    - screen OFF = 122-122 powersave
    I never notice any lag with these settings.
    But in case of lags, you can also tune the "on demand" governor by reducing the sampling rate (Setcpu advance settings) from 50000µs down to 25000µs (at the price of some higher power consumption...).

    As a result, thanks to my LorD (ClockaN) I am very happy with the high performances of my phone and its low battery drain (screen off Wifi ON 2Gonly: 2mA-5mA = -0.5%/hour) providing for my 2 days of "normal usage" between battery recharge WITHOUT ANY UNDERVOLTING !!


    Last remarks: obviously apart of risking unstabilities,undervolting does not affect quadran score !!

    OK, made new git repository, and will start from scratch...

    I have hundreds of patches and will have to really be careful what to include and what not to include..

    But please don't expect anything in the next 7 days or so.. very busy ...

    link to new repository so you guys can keep track who wants offcourse!
