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)

I'm guessing that is a technical term. Maybe someone should add it to the wiki.

On topic: I flashed r1, but am getting a never ending boot animation (not a loop).

Also tried 'fastboot erase cache'. Will report more when I know it.

EDIT: Same thing happens for me each time I try... never ending bootanimation.

    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.
