The second core is enabled only when required, e. g. when you are running multi-threaded app or game. You can enable second core permanently using adb command: adb shell "echo 1 > /sys/devices/system/cpu/cpu1/online", System Tuner Pro or just delete/rename /system/etc/mpdecision.

I just did the test, changing to 1 in online cpu1 and no difference by testing, even in 2D or 3D is all the same, I conclude that the system only uses 1 core and otherwise the second.

No, just Quadrant doesn't support multi-core CPUs. In AnTuTu Benchmark you'll see the difference between second core disabled and enabled.

Just flashed v 1.20 1512mhz on top of 3.30 fw, runs flawless but blue tint is as evident as ever on Acer panel. Seb, can you do your magic one more time?

I am also seeing the blue tint after fladhing this kernel. I know that flashing a g9788208 kernel would solve this problem. The question is what was changed?

I have the same issue unless I flash back to the g9788208 kernel also, however this kernel also gives me wakelock issues with 'AudioOut_3' on the device (out of the frying pan..) - I also tried on 3.30 so I will try again on 3.32 later in case something else has changed which may have fixed it. :(

Thanks Sebastian for the new kernel.
After enabling both Cores I got a really high score of more than 4000 on Quadrant using the OC 1836 kernel

I can't do anything with blue tint issue and never did. You must wait until HTC fix it or release source code.

I hope HTC will fix multitouch too, the problem remains in the new base (running ICS or CM9)

For the rest, v1.20 is great, fast and stable (nice to see my device run at 1836mhz, when it couldn't reach that speed with Gingerbread kernels without rebooting)

Thanks for your work, not being stuck at 1.5ghz is awsome, I now just hope HTC will fix multitouch so that games requiring such CPU speed will become playable again

OK, thanks anyways Sebastian for your work. Is there anything in the g9788208 kernel that could cause AudioOut_3 wakelock that you know of? A reboot seems to temporarily cure it but it comes back after a while.

I'm using v1.20 overlooked 1786 on a 3.25 firmware. It's working without a problem. I done some antutu benchmark with forced second core, and without.
Overcloked to 1,789 with forced 2 core and 1,51 without. Very good results, thanks for your good work.

    Modified CPU frequency tables, CPU speed limits and voltage limits.
    Temporarily fixed CPUFreq related bug in HTC kernel.
    Modified information about CPU frequency displayed in Hardware information.

    CPU Temperature daemon:

    thermald v1.0.0 (SebastianFM)
    The thermald daemon is a system service which monitors CPU temperature. It turns on the thermal sensor and sets thresholds to the thermal driver. Threshold are defined in file /system/etc/thermald.conf. If temperature reaches threshold, kernel sends notification to userspace. When thermald receives notification, it decreases CPU frequency to avoid CPU overheat.
    The stock thermald doesn't work properly because when the CPU temperature drops below threshold, or when mpdecision turns on the second core, it always sets maximum CPU frequency to the highest available frequency.
    I wrote my own thermald daemon which works very similiar, but when the CPU temperature is too high, it saves the current maximum CPU frequency and restores it later.
    My thermald doesn't parse external config file, it uses predefined thresholds.

    Downloads:
    v1.5.2, link, md5: 0b73bf76439fe002200d30717c8b931a

    Installation:
    This is flashable zip intended for install from recovery.
    I used koush AnyKernel installer, so you can flash this kernel on any ROM.
    Remember to do backup before flashing.

    OC:
    The CPU frequency 1782 MHz is stable for me but every phone is different.

    To increase maximum GPU frequency in 3D mode to 320 MHz:
    echo 320000000 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk

    zram:
    To enable zram (these commands enables 100 MB compressed swap stored in RAM):
    echo 104857600 > /sys/devices/virtual/block/zram0/disksize
    busybox mkswap /dev/block/zram0
    busybox swapon /dev/block/zram0


    To disable zram:
    busybox swapoff /dev/block/zram0
    echo 1 > /sys/devices/virtual/block/zram0/reset


    To view zram usage (size displayed in kB):
    cat /proc/swaps

    Thread cleaned.
    Stay on topic, all such issues should be handled by reporting and pm's.
    You have been warned before but failed to cooperate....
    I see that this thread was cleaned but I read some of posts before they were deleted and I want to refer to these allegations. It could be a little difficult to me because my english isn't good enought. Currently I don't know who was an author of post #1999. But I want to tell him something.
    Your whole post was a bullshit. I can say this. Do you have any prooves for your allegations? My kernel isn't 100% stock. I wanted to make overclocked kernel and I did it. I added probably best overclocking available for HTC Sensation so don't tell me that it is BASIC OC! Also I used three tables with different voltage values for different hardware revisions. For each table I added voltage values for higher frequencies, developed by me. Did you see my source code before you posted? What do you tell about changes in gpu driver? Also 100% stock, of course! 300 MHz clock settings? Change in kgsl driver which prevents from setting maximum value at start. What about bug in cpufreq that caused decreased instead of increased performance in benchmarks? It is easy to fix because you must change only one variable in code but believe me, it was very hard to find and takes a lot of time, because when I was looking for this bug I didn't have source code. About touchscreen multi-touch fix, how can you tell me that I'm laying? I can proove that first patch which I released (last Friday) is the real one and it was used by me in my kernels v1.30.2 and v1.30.3. Do you think that fixing touchscreen was easy, I wasted many hours to several tests, analyzing debug output and comparing with drivets from HTC kernel 2.6.35. Everyone can download source code from HTC site, add my patch and compile it to see that I'm not laying. I reverted this patch in my newest kernel v1.30.4 because I found touchscreen driver fixed by HTC (I added it to my GitHub because I wanted to share with other devs). On March 22 I released complete source code so I didn't violate any of GPL rules. It's funny that people permanently accuse me of violating GPL rules. Several people even have requested the source code from me before it was released by HTC. And don't compare me with other devs. I have knowledge about kernels, also I know that kernel released by HTC for HTC Sensation doesn't require too much additional changes except increased frequency to achieve maximum performance, why? It was configured, optimized and adapted by HTC people.
    I think that I made the most important changes, so no one should worry about commits count on my GitHub.

    i am still waiting for it:cool:
    My project is finished in 90%, but remaining 10% is most dificult. I'll try to finish it before december but I can't promise anything.

    SebastianFM kernel MOD v2.1 - Powerful Kernel Reset - Additional MODs

    SebastianFM kernel MOD v2.1 by axetilen & iba21 (AROMA)

    @UPDATE: If you have a problem with version 2.0 or 1.7 that after flashing, settings are not changed ===> Please Download v1.6 and try again -> It should work

    FEATURES:
    - Selectable OnDemand Configurations: Battery Save, Balance, Performance & Performance Plus (OMG! Fast like hell !!!)
    + These configurations change OnDemand behaviors
    + Battery Save: less responsive but save more battery life without significantly afftecting system performance
    + Balance: default configuration of the kernel
    + Performance: more responsive. System will be very smooth despite low frequencies
    + Performance Plus: It is Performance with 2 cores online all the time. System will be fast like never before and it can be compared to faux kernel in terms of speed

    - Selectable CPU frequencies: Max and Min (Thanks iba21 for this script)
    - Selectable CPU Second Phase Frequencies ~~~> CPU will jump to this frequency before reaching max CPU frequency
    - 3 choices of 3D GPU max clock
    - 8 choices of Undervoltage: -25mV, -50mV, -75mV, -87.5mV, -100mV, -9%, -9% plus and -11%
    - Zram on/off - script by michaelm_007
    - Delete some (not all) leftovers of other kernels which may affect this kernel
    - (NEW) Include 2 addtional scripts
    - (NEW) Add 4ext Tweaks script
    - (NEW)Selectable Read Ahead Size and i/o scheduler
    - It has full functions of Powerful Kernel Reset

    NOTES:
    - You need the latest version of 4ext recovery unless sometimes the MOD may not apply settings to your device (you may have to flash 2 times)
    - This is NOT a kernel, so you have to flash SebastianFM kernel before flashing this MOD
    - OnDemand governor doesnt support Screen Off Frequency, so don't ask for it :) => using System Tuner or SetCPU to apply is a good way
    - SebastianFM suggests making a MOD to modify init.qcom.post_boot.sh, but I can't -> I'm a little n00b in this thing
    - 9% and 9% plus: they have likely the same standby battery life as -75 but worse with heavy usage. So they are stable for almost all devices, more stable than 62.5 and 75mV and much better than -50. If your devices cannot handle -62.5 and -75, -9% and -9% plus are the best choices for you
    - I'm neither a DEV nor a pro in this field, so having mistakes is inevitable:(. Please forgive me
    - I suggest flashing this mod twice in the recovery without doing reboot to make sure it would work 100% on all devices
    - If there is the next version, the link of the older version will be disappeared because the newer version will have all features of the older one and also fix some unwanted bugs
    - You tell me if you experience a bug…

    TIPS:
    - If you already undervolted and you want to play game, let's set your max CPU freq between 810mhz and 972mhz => your device will be cool after 30 minutes of playing and you won't notice any decrease in speed while playing (loading time may increase a little bit but not significant). 1020mhz and higher will cause more heat => hot, not warm anymore
