CHANGELOG:
Codice:
*****v138*****20 August*****
Kangaroo Kernel v138 (4.4.2 ROMs only!)
.patch to upstream 3.4.103
.overclock the GPU to 487MHz. I added an extra step, not replaced what we had (see below)
.disable some more debug (less wastage of energy for greater battery life)
.disable F2FS, who even knew it was here anyway
.updates to kernel processes from CAF/upstream
.lower max i2c clock to 384KHz, to save battery
.minor updates to ONDEMAND gov from tiny4579/stratosk
.import ULTRASOUND audio drivers from latest CAF. We are using ULTRASOUND_A, made for msm8960 (improves audio playback)
4.4.2 SENSE/GPE
KANGAROO KERNEL V 138

TUTTE LE VERSIONI PRECEDENTI: QUI

4.4.3 SENSE/GPE

CHANGELOG:

UPDATE: Kangaroo Kernel MKIV v072
21 Oct changelog:
.cleaned up MAKEFILE kernel build flags
.some power efficiency enhancement patches, picked from NVIDIA for a15 devices (for greater battery life)
.reverted some msm_hsic_wakelock patches to try to reduce wakelocks (to improve standby times)
.introduce userspace voltage control (min is 650mV)
.some upstream patches for compression
.optimize memcpy for cortex-A15 to memutils (xboxfanj, this is for overall efficiency)
.some Cortex-A15 optimization patches from NVIDIA
