[KERNEL] Overclocked kernel v1.4.0
Based on the newest HTC source code.
Overclocked CPU, added optimized CPU frequency tables with CPU frequencies up to 1836 MHz and L2 cache frequencies up to 1566 MHz.
Increased CPU voltage limits (700 mV - 1400 mV).
Added CPU Voltage Table interface that allows voltage adjustment.
Overclocked GPU, increased maximum GPU frequency in 3D mode from 267 MHz to 320 MHz (300 MHz by default), increased bus bandwidth.
Added USB OTG
Enabled USB Host.
Added support for different types of USB peripherals: USB Hub, USB mass storage devices (e. g. USB HDD, USB Stick, MP3 player), USB HID devices (e. g. USB mouse, USB keyboard, Wireless mouse or keyboard with USB receiver).
First release built from kernel source code vigor-ics-crc-3.0.16-d0049f1. Thanks to HTC!
Added higher values to L2 cache frequency tables.
Updated CPU frequency tables.
Fixed ACPU and perflock to allow setting different maximum CPU frequency than highest available.
Fixed issue with changing minimum and maximum CPU frequencies by the system daemons. Replaced thermald.
Extended CPU voltage limits.
Added 300 MHz GPU clock settings.
Increased GPU bus bandwidth in 3D mode.
Modified Adreno220 drivers.
Overclocked GPU in 3D mode to 300 MHz by default, maximum 320 MHz.
Enabled USB OTG.
Added NTFS support.
Added USB Host.
Added USB storage and USB storage drivers.
Added USB HID.
Added drivers for USB HID devices.
Added support for zRam swap.
Enabled CPUFreq stat.
Added CPU Voltage Table - interface that allows adjustment of the CPU voltage (thanks to snq-, faux123 and show-p1984).
Based on new kernel 3.0.16-g480e1b0 (August 3).
Based on new kernel 3.0.16-g4a9c8a3 (March 10).
Fixed CPUFreq, mfreq related bug (which caused performance issues).
Three kernel variants with different maximum CPU frequency.
First release based on kernel 3.0.16-g837f300.
Modified CPU frequency tables, CPU speed limits and voltage limits.
Modified information about CPU frequency displayed in Hardware information.
CPU Temperature daemon:
thermald v1.0.0 (SebastianFM)
The thermald daemon is a system service which monitors CPU temperature. It turns on the thermal sensor and sets thresholds to the thermal driver. Threshold are defined in file /system/etc/thermald.conf. If temperature reaches threshold, kernel sends notification to userspace. When thermald receives notification, it decreases CPU frequency to avoid CPU overheat.
The stock thermald doesn't work properly because when the CPU temperature drops below threshold, or when mpdecision turns on the second core, it always sets maximum CPU frequency to the highest available frequency.
I wrote my own thermald daemon which works very similiar, but when the CPU temperature is too high, it saves the current maximum CPU frequency and restores it later.
Currently my thermald doesn't parse external config file, it uses predefined thresholds.
thresholds 75 78 81 84 87
thresholds_clr 72 75 78 81 84
actions cpu cpu cpu cpu cpu
action_info 1296000 1188000 918000 756000 384000
If you include my thermald in your ROM or kernel package, please don't forget give credit to me.

This is flashable zip intended for install from recovery.
If your device is S-ON, installation will fail but PH98IMG.zip will be created on SD card. Reboot into bootloader, kernel will be flashed from this file.
The CPU frequency 1782 MHz should be stable but every device is different.
To increase maximum GPU frequency in 3D mode to 320 MHz:
echo 320000000 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk
zone23, for testing and for AnTuTu scores, thank you.
con247, my installation scripts are based on con247's work, thanks.
