Hello, you happen to have a uninstaller made up for grouper? Like this one? Awesome kernel but need y-cable support and modules for external wifi adapters... Thanks!
Flash your ROM back over the top
Thanks man. I was just worried about all the init.d scripts etc. This kernel is awesome and complicated
I ran the awesome kernel cleaning script and flashed a different kernel and it seems to be working perfectly. Thanks for the heads up!Hi, sorry for the idiotic questions:
* when you say "the most customizable kernel" do you intend stuff like frequencies and the like (like using the tool you suggest in the main page) or do you also refer to other paramenters ?
** Are these parameters stuff in the standard init.d scripts?
*** Is this stuff distro related?
*** Is this stuff kernel related?
More simply:
* Can I use this kernel on MinimalOS with any improvement on the performance?
* Can I use this kernel on ResurrectionRemix with any improvement on the performance?
* Can I use this kernel on Cyanogenmod 12.1 with any improvement on the performance?
In any case I would like to thank everybody involved in the development of this kernel: it makes my stock 5.1.1 snappier and at least usable!!!

Has anyone tried using the 20150501 release with the latest CM12.1 snapshot?
I had the snapshot installed with F2FS and from this I think the CM12.1 stock ramdisk and cmdline should already support F2FS but after I flashed the kernel it's stuck at the CM logo.

I could have a look later. On which rom is this? (the CM12.1 snapshot?)
Stock on the grouper/tilapia only goes to lp iirc (which works fine, tested on 5.1.1 LMY47V).
I had the issues both on snapshot and the cm 12.1 nightlies. Another thing that is weird, is that when I use kcontrol and try to open Low Memory Killer, kcontrol crashes. I flashed parrot univ. mod just to see if it changes anything lagwise and found by chance, that kcontrol starts working fine. Just flashed an old backup of cm12.1 nightly (latest) without parrot mod and kcontrol crashes again, when trying to open Low memory killer. Flashed parrot again...kcontrol works. Anyways, I had some trouble with busybox since cm 12.1 seems to use a systemless root method and if I read your instructions right, busybox is needed either in system/xbin or system/bin, because of the script. Wlan worked though. I now flashed supersu 2.52 to get a non systemless root. Installed busybox and flashed your kernel again. I will see if I get the no sim inserted problem again. lsmod only shows some kcontrol gpu tegra module. Wlan and 3G is working at the moment, as in previous tries. So right now my settings are su 2.52, latest busybox (busybox on rails), parrot univ. mod. It seems like init.d is not being executed.
I was looking a way to change the max GPU clock without reflashing the kernel. Just want to enable aand disable the overclock. It's there a way? Using terminal emulator or something?

Hello, thanks for the kernel.
Is there any way to get logcat working with this kernel? I flashed it to SlimKat and I can't seem to get logcat working again... All I get is this:

The download link gets me to the bricked.de download page and there you can search and download. There is an issue with the dropdowns I just noticed, but that won't keep you from downloading.
This seems to be an IPv6 issue. I will have a look when I have time.
EDIT:
Had some time and fixed it

Welcome to the most customizable N7 kernel on xda
Bricked-Kernel Nexus 7 (grouper)
Replaced NVIDIA's strange hotplug manager with my own: tegra_mpdecision
Features:
Based upon Googles tegra3 source
Fixed section mismatches
Various other fixes (look @ github)
Compiled with gcc4.7.2 toolchain (linaro 09.12)
Replaced NVIDIAs hotplug manager with tegra_mpdecision (better battery life + performance)
Extensive sysfs interface for mpdecision with all the tuneables you want
Highly modified ondemand governor for tegra3 & mpdecision (this is the only recommended governor atm)
Fixed usage of 51Mhz clock
GPU OC (416/484/520Mhz)
Truly variant free CPU OC for all devices (51 - 1600Mhz)
Fixed max cpufreq resets throughout the kernel
All cores now use the max frequency (before: only in singlecore, otherwise -100Mhz)
Undervolting (faux123)
Default clocks: 102min & 1300max (+100Mhz overclocked) & 475 Maxscroff
earlysuspend/lateresume for ondemand including special screen off settings to save power
Aroma Installer by amarullz
cmdline interface for cpu min/max/maxscroff/gpuoc/scheduler/governor
---Just flash the kernel with your desired settings, no more need for oc apps. Reflash if you want to change sth. It's that easy!
FSync Control by Ezekeel
export t3 variant to debugfs by faux123 (adb shell cat /sys/kernel/debug/t3_variant)
lowered panel min brightness to 8
ZRAM
enabled NFSv3&4
Check the compare links for the rest
Where is tha Changelog???
There will be no more changelogs.
Instead the download pages were outfitted with compare links to github for each download.
How to install?
Flash through recovery. #done.
Where to complain about errors/bugs?

23It is sad to see @show-p1984 not updating its kernel anymore.. It had a great start and there it seems to end
Yeah right. Try rewriting half of the i2c transactions just to get a proper transfer when the n7 is sleeping and I will release it asap. Otherwise gtfo with your attitude.
Some ppl seem to believe I am only sitting around and juggling my balls all day long, so that posting "this kernel is dead" might get me off my lazy ass.
Just pray that this doesn't backfire one day.2216Knowledge base:
What is tegra_mpdecision?
100% kernel based multi core decision! (should cpu1/2/3 be online or not, do we need the low-power/ninja core now?)
This replaces the stock nvidia hotplug solution.
Check /sys/kernel/tegra_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (20000)
delay = time between checks (130)
pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)
scroff_single_core = Force low-power mode if screen is off (1)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
min_cpus = min cpus to be online, cannot be < 1. Default: 1
max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4
idle_freq = a value against that will be checked if a core +/- is requested. (475000)
lpcpu_up_hsyteresis = minimum number of requests that have to be send in order to switch to low-power mode (4)
lpcpu_down_hsyteresis = minimum number of requests that have to be send in order to switch to g-mode (quadcore-mode). Overridden by a requested freq that is higher than the max supported lp-mode frequency. (2)
If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.
If any other cpu is above that value and a core down of that cpu is requested, nothing will happen. (otherwise it would now put down that cpu even though it is still working, which isn't what we want)
Hot plug thresholds (aka now it gets 'complicated')
This small formula calculates which value will be used: (number_of_cpus_online - 1) * 2
The result of this formula will be the nwns_threshold where a new cpu is hotplugged.
The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.
nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged
twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)
Example:
One cpu is online.
(1 - 1) * 2 = 0 ergo:
nwns_threshold_0 = cpu1 will be hotplugged at this value
((1 - 1) * 2) + 1 = 1
nwns_threshold_1 = cpu0 will be unplugged at this value
This will regulate when we switch to lp-mode, effectively replacing the quadcore g-mode core with the ninja lp-mode core.
Two cpus are online.
(2 - 1) * 2 = 2 ergo:
nwns_threshold_2 = cpu2 will be hotplugged at this value
((2 - 1) * 2) + 1 = 3
nwns_threshold_3 = cpu1 will be unplugged at this value
etc...
(all times are in ms)
If you want to see the mpdecision magic happening:
Code:adb shell cat /proc/kmsg | grep 'MPDEC'mpdecision's input event boost, aka project butter
This will boost your min cpu speed if you touch the screen or press a button and gives you full control.
In those events the min cpu freq will be risen to a predefined value (look below) on every online cpu. This boosts overall reaction times and smoothness a lot. (works similar to the qcom mpdecision binary)
Configuration files:
root@android:/sys/kernel/tegra_mpdecision/conf # ls
boost_enabled
boost_freqs
boost_time
All of them work like the usual sysfs files, except one special case:
boost_freqs will list all frequencies from cpu 0 to cpu x. Cpu 3 and any following cpu will share one frequency.
To change those frequencies echo the cpu number + the frequency in khz. To change the boost freq of cpu3 (and 4,5,6,7,8, etc) the echo would look as follows:
for cpu0:Code:echo "3 1026000" > /sys/kernel/tegra_mpdecision/conf/boost_freqs
Code:echo "0 1026000" > /sys/kernel/tegra_mpdecision/conf/boost_freqs
Defaults:
Code:cat /sys/kernel/tegra_mpdecision/conf/boost_freqs 910000 910000 760000 620000Recommended governor?

Why do I have no WLAN?
This kernel is too big for our boot.img with WLAN included into the kernel, so it is built as a module. That means it needs to be inserted into the kernel upon boot up, which needs to be automated for maximum comfort = userinit (init.d) support.
The zip adds init.d support to your ramdisk, if that fails for some reason the wlan module cannot be inserted.
if
doesn't show this:Code:adb shell lsmod
Then init.d support is probably missing.Code:tun 14060 0 - Live 0x00000000 cifs 239646 0 - Live 0x00000000 bcmdhd 433083 0 - Live 0x00000000
You can test it by going to /system/etc/init.d/ and executing 00wlan.
Code:adb shell su . /system/etc/init.d/00wlan
Wait a few seconds and try to enable wifi and repeat the above lsmod command (should now show bcmdhd as live, you can execute 01cifs and 02tun too).
If WLAN now works, init.d support is missing.
You need to have busybox installed in order to be able to get init.d support going, this shouldn't be a problem for most people, since it is usually installed when rooting your phone anyway (and who does unlock but not root their phone? :/)
It does not matter if busybox is installed in /system/bin or /system/xbin, my script will detect the location upon flashing and patch the ramdisk accordingly.
If no busybox is found, the script will add init.d support to your ramdisk with the default location: /system/xbin/busybox. All you need to do is install busybox there and reboot your phone.
