Version

v2.1

Description

i send you to solve one problem, before some months i was testing wifi drain on stock rom and i told you that if i remove the following file /system/etc/wifi/ default_ap.conf wifi seems better.. it should disable at & t auto connect but it causes alot cpu drain on the following service " nvcpud".. check it out.. i renamed(disable) the following file /system/bin/nvcpud to nvcpud.off and everything was fine after rebooting without any defects... maybe that's why some users report performance loss due to that process, i hope that helps

Update 1 : i had disable for 2 days that service, unfortunately when you have incoming or outgoing sms phone reboots.. so we need this service on

Update 2: please add those lines back again on default_ap.conf (fixes nvcpud problem)

network={ ssid="attwifi" key_mgmt=NONE vendor_spec_ssid=1 }

According to the following post it may has to do with a missing or invalid kernel driver module:

http://forum.xda-developers.com/showpost.php?p=42624203 --> nvcpud is your nvidia tegra 2 cpu daemon which takes care of your graphics. Its because of your improper driver module (kernel).

The same above post later discussing about completely disabling the nvcpud but I really do not know if that would have any site effects.

CM has patches for the nvcpud service which disables the daemon once it was initiated http://review.cyanogenmod.org/#/c/45149/ or here where the files were added: https://github.com/tpruvot/android_device_samsung_i9103/commit/1350ea36c875cd278951f757be6b84387d8fcea9
