Just FYI to those who are using Touch Control. Before discarding this Kernel out your system, f.K r395 is using r384 module. It is working on my GN perfectly. Sorry if this is not Kernel related, just want to share this to my fellow f.K avid users. Thanks Franco for this release, I loved the reincarnation of ASRAM.

So what you are saying is that touch control works with r395?

I'm still all about my 245 255 340, -4 0 5, -5 Trinity, OMAP disabled, CAB disabled. Check my settings post linked in my sig. :)

you should give mine a whirl lol 200 200 265, -6 0 8, -14 trinity, 6 omap, CAB disabled (personally I dont like making the multipliers too high since its more likely to cause burn in and makes the screen overly bright)

Just out of interest can you guys save and load profiles or is it still adjust the sliders to match peoples profiles? I'm just curious that's all. Over in the n5 forum me and @vomer are hosting all the screen profiles created by other members and its very easy to just load another and screen off / on.

Pretty nice! A bit too dark for my panel though, which is dark to begin with and why mine are amped up. :)

Edit: Mine have been in need of an adjustment since all the kernels incorporated mpok's purple tint fix. I've always had trouble with yellow at low brightness, moreso after, so I'm thinking 230 235 340 might be my new settings. :good:

Yes it does now. Be sure to choose nightly #385 (or is it r384?), like what he said.
I'm on touch control now, working fine with r395 :)

I have disabled ART, as I feel dalvik+francoKernel is much faster than ART+(whicheverKernel).

I was running ART with r394 previously, so it should also with r395, haven't personally tested it with ART, but not willing to do so now. I had bad experience with ART previously (seems slower than dalvik on mine), and besides initial boot up on mine takes around 45 minutes if I'll be moving to ART again. Too many apps.

Thanks for the great kernel. I flashed R395 on Cm11 - 3Febr with art enabled. It seems the kernel took over the governer and scheduler of CM11.
What are the original one's of this kernel?
As I assume these are the best tested.

Yea, I know AppA can do xxxx job, AppB can do yyyy job, AppC can do zzzz job, but all these job can be done silently by using script

That's exactly how I got involved in all of this 2 years ago; init.d scripts are a gateway drug! :D

Trinity and OMAP Gamma contrasts are in the 2nd post of this thread along with a number of others, and all that aren't are documented here:

    I hate big OPs.

    Works on all roms. r390 and newer versions are ONLY for 4.3 or newer.

    F.A.Q:
    1. My device rebooted or crashed, how can I help?
    A: Get me /proc/last_kmsg on pastie.org.
    2. Battery sucks, my device is not entering deep sleep. FIX PLOX!
    A: Fix it yourself, it's an app waking your device up not the kernel's problem
    3. Signal is dropping since I flashed the kernel, amg u sucks!
    A: The kernel has nothing to do with gsm/cmda signal. Make sure you have the latest radios
    4. Do I need to wipe anything when flashing this kernel?
    A: No.
    5. Does this kernel has X or Y mod?
    A: Learn to read, everything you need to know is in the features list, changelog or public repo.

    Just woken up and feel like my head is going to explode already this last 5 pages is crazy

    haha. It's been a crazy two days. :) But it's been a blast.

    Now, sleep is over, time to get back to work!

    I got these from that thread:

    so it makes much sense, to make the min_sample_time as low as possible (?), but how low? what's the most appropriate sample time for battery and performance?

    for the timer_rate, franco suggested 30k to consider the CPUs latency. What has it to do with the cpu's latency?

    he also said min_sample_time doesn't have to be in multiple of timer_rate.
    in my case, all my timers are in 20k, which works fine as of now. But i must be missing some things, because I just saw somebody post these values, and no detailed explanation for having them.

    Yes and no. Here's what we're thinkin' so far.

    THIS POST WILL BE A RECAP OF THE LAST FEW PAGES OF RESEARCH! :)

    This was my original settings that I've been using for weeks:
    above_hispeed_delay: 20000
    go_hispeed_load: 50
    min_sample_time: 40000
    timer_rate: 20000
    So to make the short hand easier, we kept it in that order and just said: 20000/50/40000/20000 became 20k/50/40k/20k became 2/5/4/2. Make sense?

    Here is a breakdown of what they each mean:
    -above_hispeed_delay: Once speed is set to hispeed_freq, wait for this long before bumping speed higher in response to continued high load.
    -go_hispeed_load: The CPU load at which to ramp to the intermediate "hi speed".
    -min_sample_time: The minimum amount of time to spend at a frequency before we can ramp down.
    -timer_rate: Sample rate for reevaluating cpu load when the system is not idle.

    This is a good explanation that I wrote back on page 3038:
    -above_hispeed_delay: higher = better battery, lower = better performance. (100k is default)
    -go_hispeed_load:.......higher = better battery, lower = better performance. (50 is default)
    -min_sample_time:......lower = better battery, higher = better performance. (60k is default)
    -timer_rate:.................higher = better battery, lower = better performance. (20k is default)
    So Google's default is 10/5/6/2. Lower numbers are all better for performance except min_sample_time (there higher is faster). So our goal is to find a sweet spot.

    The default 10 is for "Once speed is set to hispeed_freq, wait for this long before bumping speed higher in response to continued high load." So we think 10 is too high, but if you go too low, then you'll be using the higher freqs a lot more than you need and it will hurt the battery. So we are leaning towards 6 (60000) for above_hispeed_delay.

    The default 5 is for "when the CPU hits X% amount of load, then jump to the hispeed_freq." Again if this one is too low then it will cause the higher freqs to be used more often then they need, so we actually turn go_hispeed_load up a little bit to 7 (70).

    The default 6 is for "how long do I wait before lowering the clock speed from what it's currently at." So the lower we put this, the better battery will be. We're still trying to decide between 3 (30000) and 5 (50000). Osm0sis is getting more lag at lower levels, and finds the best performance mark at 5. So we turn min_sample_time down a little from stock to help with the battery.

    The default 2 is for "wait this long before changing the clockspeeds from what it's at now." While technically 2 sounds better because it's changing more often, Franco believes that by setting the timer_rate to be the same thing as the CPU sample_rate (which is preset at 30000), then that will make the CPU more efficient at switching. So we increased it from 2 (20000) to 3 (30000).

    So TO RECAP: Using the stuff from above, Google's defaults for these settings are 10/5/6/2 and we are changing them to 6/7/3/3 or 6/7/5/3 (again, still testing that third number for the min_sample_time).

    Does that make sense for everyone interested in following along? Any questions? Feel free to try out these settings yourself (the easiest way is with Franco's app or something like Trickster). We want as much feedback as possible on this.
    The next kernel release will have the totally tweaked settings for everyone to test without having to change their own stuff.

    Kernel Emergency Settings Reset Zip

    Alright so here's something that's been requested for awhile.

    I wrote it up recently with Franco's stamp of approval, so I'm posting it here now. Please direct people back to this post from other threads.

    This can/should be everyone's go-to when experiencing problems after updating to a new kernel build, you get stuck in a bootloop, or you think there's a conflict between ROM and kernel (or kernel tweaking app) you can't track down, since likely some leftover settings (voltages, etc.) are at fault. It's also useful if you just want to make sure you're running clean defaults. This should work on any device franco.Kernel and f.Ku support, as well as a variety of other devices, kernels and control apps: eXperience (Free/Pro), GLaDOS Control, TricksterMod, Trinity Kernel Toolbox, ROM Toolbox (Lite/Pro), SetCPU, Faux123 Kernel Enhancement Project, Performance Control and Synapse.

    Flashing this via custom recovery of your choice will delete the kernel app settings file(s), disable init.d and userinit.d scripts by moving them to a subfolder (/system/etc/init.d/off/ and /data/local/userinit.d/off/ respectively) and wipe cache and dalvik-cache for good measure.

    Hopefully it helps!


    Note: If your ROM has a Performance/Tweaking App built-in you should also manually disable any Set On Boot options it has. For example, I couldn't include clearing CM's Advanced Settings since they're built into the main com.android.settings/Settings.apk along with a lot of other Android OS settings (APNs, Developer Options, etc.), so to run clean and without conflicts on CM you need to unset them yourself.

    You should also avoid having more than one control app installed at a time. Conflicts have been reported even with everything "unset" in two apps.

    I also chose not to disable anything your ROM may have in /data/cron or /system/addon.d since some rely on it heavily, so you can choose to review those directories' contents and whether you want to leave them enabled on your own. I also left out disabling sysctl.conf since that's done by f.K and the Franco's Dev Team scripts, and also seemed a bit heavy-handed for this zip script.

    The following voltages are just as a reference. DO NOT enter them; your device may not be able to handle them this low, causing freezes and reboots. They are here so that people can compare their stable voltages after following the UV guides linked below, to see how our devices compare. Every device is different, so again, DO NOT enter them.
    mpu_voltages:
    1804mhz: 1425 mV
    1728mhz: 1375 mV

    1228mhz: 1125 mV
    1036mhz: 1075 mV
    729mhz: 925 mV
    537mhz: 825 mV

    332mhz: 1025 mV
    266mhz: 925 mV
    133mhz: 825 mV

    core_voltages:
    512mhz: 1050 mV
    384mhz: 975 mV
    153mhz: 800 mV
    There are some battery savings from UVing but they aren't extreme. If you do not know how UVing works and/or you can't/won't read to properly build your own voltage profile, then just stick with the defaults Franco has already UVed. If you do still want to learn to UV then, once again, everyone should build their own voltage profile for their own device. Read this, this, this, and this for starters on UV methods. You don't know how your device will do until you learn and try.

    As a sidenote, if anyone else wants to share their voltages for comparison the easiest way is to copy the contents of the 3 voltage files (mpu/iva/core) in /sys/class/misc/customvoltage/ - they look (almost) exactly as the sections above.
    Fsync on just in case anything ever happens I want my data protected. That said I do disable it temporarily if I ever want a bit more performance in an app or game. SR is hardcoded disabled in the latest builds.

    The other thing worth noting is I set my color settings on boot with an init.d script. Doing it that way you can end up with a completely different result from the same values. The contrast, blacks and colors are much more natural. Also it's seamless which is nice; they take effect during the Google logo. Attached is my init.d script for that. Alter it to your own color settings, remove the .txt extension, push to /system/etc/init.d/ and set the correct perms; rwxr-xr-x (chmod -R 755 /system/etc/init.d in Terminal Emulator).

    900colorsettings can be found with my other init.d scripts (from Franco Dev Team), here: https://s.basketbuild.com/filedl/devs?dev=osm0sis&dl=osm0sis/scripts/900colorsettings

    Note: On my new replacement screen, setting the color multiplier too early in the boot (any time before the boot animation) made everything look dark, oversaturated, uncontrasted and dusky; basically the opposite of the way it used to work on my old panel. Adding sleep 2; before that line in the init.d script fixed this, so experiment if your panel is more like my new one, and the init.d as-is after you put in your settings makes it look worse.

    [ New init.d script with my new colors. I need the sleep 4 because of my problem in my "Note" above, so comment it out if you don't need it, it will make it look worse. Previous download counts were 1880, 646, and 307. Thanks everyone! ]
