How is this working out? I've been receiving good feedback so far, and my Grouper feels like a new device altogether, not that I use it that much, but its nice to feel it not lagging its ass off like before.

Uuuuuuh yeah!! This is what i was waiting for!
Thank you franco, it is really waaaay better with your kernel! Finally my n5 is taking a rest on the table and surf the web with the good oldfashioned n7!! Way smoother and almost lagfree! Great work!

I just flashed the factory 4.4 images on my grouper yesterday. This was a nice surprise today. I used FKU to backup the stock kernel and then installed r76. So far, so smooth. Thanks!

This thing is running so much better so far! I am running twrp and flashed with FKU without problem. Acts like a new device. Thanks again Franco!

My Nexus 7 has never felt as smooth and lag free as with the latest r76 kernel. Great job and thanks for continuing to support this device :)

tried to flash via FK app (free) and it installed r75 = bootloop

had to install manually, is this a app bug?

Hi,

isn´t this Kernel (R76) suitable for a rooted Nexus 7 grouper running Android 4.2.2 ? Used Flashify to flash the boot.img and bricked my Nexus 7 ...
not booting any more....

So you downloaded an image from a directory called "4.4" and you're wondering if it will/surprised that it didn't work on Android 4.2? Come on... :rolleyes:

r76 won't even work on Jelly Bean 4.3, because it's a KitKat 4.4 kernel.

Flash of r76 through FKU worked great for me. Grouper running very smooth on stock rooted. I'll have to report back on battery life once I've been running it a while.

    Disclaimer to moderators:
    Slight OT is fine, but when users decide to act stupid they should be dealt with with the appropriate means - its really annoying for me when OT turns crazy. Please put the warning/ban hammer anytime any of you think there's lack of respect and/or too much unwanted OT crap - but if it doesn't meet this criteria let the OT posts alone. Thank you.

    Cheers!

    Fsync toggle:

    It's disabled by default. Enabled = stock IO speed while having data integrity; disabled = more IO throughput but less data integrity

    echo Y > /sys/module/sync/parameters/fsync_enabled (N to disable and Y to enable)

    GPU clock interface:

    To check the current GPU frequency:
    cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc

    To change it:
    echo X > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc (change the X with your desired value. Should work up to 750Mhz at least, beyond that is pure madness)

    r62 - Where is the lag?
    * 99% rework of the Hotplug driver. Cores are intelligently managed. Always 2 cores are online to diminish thread migration and all the intrinsic operations that are inherent of onlining and offlining cores. If the load is high enough the other 2 cores come online
    * Custom changes to interactive that now reacts a bit better and more intelligently to load changes, specially during big load, which will majorly improve gaming performance
    * Interactive tunables are scaled from the Hotplug driver based on either there are 2 or 4 cores online. If there are 2 online it uses the normal tunables, if there are 4 they get tuned for maximum performance
    * Merge all the work from the usual suspects, which contains the special partition mounts
    * Bunch of other custom patches and other patches from upstream to improve IO handling
    * No more Youtube lag as far as I know

    By the way I think I fixed that bug where the device could be stuck in a lower frequency (I think that was the problem AFAIK) and driver it unusable unless rebooting. Let me know if thats fixed, which I tried to fix anyway.

    Just pushed r48. Re-merged original hotplug driver and changed just a few lines to make it a little bit lighter. Should give a little extra power now. Also fixed the UV interface, you won't be able to input more than 600mV. Merged a few changes from upstream too. Hotplug options from my app will be gone with this driver change. Also it won't be dual-core minimum by default, will hotplug normally. I plan to re-add the options to change the hotplug parameters sometime in the future.

    Happy new year folks, time for r77!!

    * Merged interactive governor improvements from FK for N5
    * Merged Hotplug driver improvements from FK for N5
    * Merged touchboost generic driver from FK for N5
    * Other misc patches merged from upstream
    * Added CM11 support

    Thanks to osm0sis who kindly sent me the correct ramdisk changes for this release. Hope you enjoy this.
