From overclocker to overclockers... LordMod kernel V5.5 CFS and V4.5.2 BFS
This is my first ever ROM and custom kernel for any device..
I tested it for a long time and I think that it's ready for the community..
I've only wanted to implement smartass because everybody (almost) wants it, but the project took me much further than I imagined.. I've lost 7 days on this so don't be harsh on commenting my work. I'm a BEGINNER in kernel building and ROM modding.
ROM is build from the latest commits of CM7
Kernel has been taken from “teamdesire” and modified a little to suit everybody!!
For those who care – Quadrant score is about 3400 on 1800MHz PERFOMANCE mod I use BFQhs (ATM) PUV edition @ 122/1380MHz 24/7
Decided to update only the kernel... because ROM is basicaly CM7 nightly...
I'll include kernel update.zip with and without SD Card Read speed increase patch!
KERNEL (for CM7 only, apparently works great for MIUI):
Kali-'s kernel 2.6.32.28
Battery drain fix included - by teamdesire (allready implemented in CM7)
Chose default I/O scheduler
New Adreno 205 drivers like in nightly kernels
Kernel patched to 2.6.32.41
SMARTASS governor added and tweaked
CPU freq table totaly rewriten with lower voltages
OC up to 1990 MHz, min 122 MHz – DON'T GO OVER 1800MHz EXCEPT FOR SHOWOFF AT THE BAR I AM IN NO WAY RESPONSABLE FOR DHD SMOKING!!!
Patched libsqlite.so to disable db loops – thanx to ownhere
Under volt editions, UUV edition might not work for all.. use -25mV edition
Tiny RCU subsystem, Bloatware edition
Low level memory tweaks and fixes
Fixed some bugs regarding sleep/awake for video driver
Fixed first boot Wlan crash
Implemented 2 way recording patch by avs333 and skvalex - thread - only kernel 4.4.1 and now 5.1
Removed some debugging and statistic logging
GPU+ patch for better 2D and 3D perfomance (thanx -snq)
Disabled write cache support to enhance SD write speed
Updated drivers from HTC Saga and HTC Vivo - All glory and credits go to James Zdziebkowski for porting drivers
[*]Tweaked Interacive and Ondemand governor[*]Added patches and fixes from latest CM7 kernel regarding Wlan chip, USB...[*]Added USB accessory gadget support - patch from newest CM7 kernel[*]Tweaks for video driver - patch from CM7 kernel (modified by me for Saga driver)[*]Hopefully compatible with all AOSP ROMS for DHD - CM7 all bases, MIUI, UltimateDroid...[*]Implemented USB thetering support - by James Zdziebkowski
"How to" for CM7 users:
Do a nandroid backup
Download desired zip from below
Copy to SD card
Go into recovery
Wipe cache partition
Wipe Dalvik cache
Flash from zip
Use 5.6 CFS or 4.5.2 BFS V400!
BEFORE flashing set your MIN freq to 230 or disable Set On Boot in Cyanogen Perfomance Menu!!!
V5.0 replaces some system libs for the video to work, so please do a BACKUP before flash if you want to return to other kernel!! - Use this if you want to restore to default libs, and than without restart flash kernel older than 4.5.2 - zip, older than 4.6 - zip
Scheduler flavours: BFQ I/O, BFQ I/O with hierarchical schedulling (only CFS), V(R) I/O
BFQhs V5.6 - CFS zip
VIO V5.6 - CFS zip
-25mV zip
-50mV zip
UUV zip
PUV zip - This is heavely UV even for UUV edition.. going from min 775mV trough all the freq range. If UUV worked for you, you must test this It's working fine for me 122/1380MHZ 24/7
Restore defaults zip
Restore defaults SCRIPT
If you want SD card speed patch, put this file into /etc/init.d folder and give it executable perrmision. It can corrupt your SD data! CAUTION - BACKUP

To have this kernel on MIUI, follow these simple steps from htctouchelfin!
AGAIN - don't FORGET to do a nandroid backup prior to flashing!
No need for screen shots, because everybody knows how CM7 looks like.
Governors for NOOBS:
interactive - Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle. When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.
smartass - Is an improved version of interactive governor
ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
