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.

So if I can work out how to unpack a boot.img and pack it back up with your
zimage will I be able to 'fastboot boot boot.img' rather than trying to make a
zip file

Thanks.

Ok I have H again now after restoring boot and system, does that help? Or do you
need a logcat of when I'm using the kernel?
Thanks mike1986 I thought it was just boot but did system as well just to be
sure

Other than trying the obvious ****s, how does it feel compared to stock? If you
can't feel a difference can you benchmark it and tell me if anything changed
from stock? I kinda sure hope so, made enough changes for that

Weird. Can you wipe the caches etc just to be sure? If still bootlooping I'll
compile something different later.

Can confirm the bootloop on the second flash of your kernel (from the zip mike
made). The first flash through recovery went fine and the system booted up
without problem. Had wifi and signal but no data and everything was running
smoothly.
Rebooted into recovery, restored my backed up boot image and booted back into
Android without problem.
Second flash of your kernel resulted in a bootloop at the first google screen
(didnt get as far as the animation). Went back into recovery and wiped the cache
and still bootlooped. Recovered boot.img from backup and booted fine. I have
tried this 3 times now and its bootlooping everytime with your kernel but I dont
know why it booted fine the first time..
Hope that was some help.
Mark.

Doing a cleaner build now since I got two reports of bootloops when this
condition was met:
1 - Flash my kernel. System booted fine
2 - Restore original boot.img
3 - Reboot fine
4 - Flash my kernel back. Bootloop
As I don't the device I'm going step by step. I wanna make sure its stable with
a few tweaks, then adding all my gizmos.
This will get updated very frequently in the next days as I start to get
feedback.

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
> Click to expand...
> Click to collapse
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.
> Click to expand...
> Click to collapse
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)
> Click to expand...
> Click to collapse
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.
Download counts for the previous versions: 790; 2678.

Sure. Happy to post my franco.Kernel settings here for anyone who wants to
try them. I'll keep these up-to-date if I change them.
These are my f.K settings, my DirtyV settings can be found here.

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.

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! ]
