it unlocks many cool features!
- NEO 17 (r8 - codename Butterfly) changelog
- Changes (from r7):
- • added ondemandb ('b' for battery efficient - ondemand with stock - more battery-friendly thresholds & settings)
- • add sampling down option to ondemand, ondemandb, ondemandX to control from userland
- • fixed up UV voltage table - UV should work now [testing]
- • lowered transition latency to 40 µs (more stability - thanks to pawitp for the idea !)
- • fixed led-notifications & touchkey lockup/hanging (thanks to pawitp)
- • some general ARM + sha fixes
- • switched to August (08/2011) snapshot for the toolchain
- • lowered optimization flags to mainly graphite only (more stability, in some areas more performance)
- • tweaked savagedzen to make it more usable (still bumpy from time to time)
- • +/- led-notifications kernel [if not wanted: disable via quiet hours in CM7, disable in MIUI] (testing effect on battery runtime when disabled - need feedback in XDA thread)
- • improved battery runtime with failed suspend attempts [less cpu & battery burning - EXPERIMENTAL]
- • made some corrections to the S98system_tweak script
- • (probably noticable) faster booting
- • when comparing "stock" cm7 kernel with this one use ondemandb governor - this should be very similar
- to the ondemand governor from stock; ondemand governor in this kernel is more aggressive (smoother and clocks up faster)
- NEO 17 (r7 - codename Butterfly) changelog
- Changes (from r5):
- • switched to preemptible tiny_rcu with priority-boosting
- • switched from platypus optimization flags to stock flags for prebuilt modem driver + graphite & additional tree/loop optimization flags for rest of kernel
- • rwsem improvements
- • some more ARM (platform) fixes
- • MTD fixes & improvements
- • lowered ramping-up threshold of ondemandX to 85
- • a few more s5p fixes
- • overall more performance & more consistent experience (probably less lags/smoother)
- • [not sure if activated] some more randomisation [more security]
- NEO 17 (r5 - codename Butterfly) changelog
- Changes:
- • [samsung upstream] improved usb signal quality
- • reworked & updated system_tweak script included [rp_filter disabled so VPN should work out of the box, faster ringing during call, some speed-ups & tweaks in several areas]
- • BFQ as default i/o scheduler (in script)
- • noop should be default without scripts [via kernel]
- • back to well established & tested platypus optimization flags
- • [cm7 upstream] more accurate battery stats [no 100% after unpluggin usb-cable/charger]
- • re-added & re-ported docksound audio support [needs docksound redirector app]
- • even more battery runtime improvements
- • refresh rate back to 68 from 72 - less issues
- • re-added support back for Telus Fascinate
- • logcat is now enabled by default [doesn't seem to make a difference in battery runtime with GB bootloaders anymore]
- • [cm7 upstream] added protection against accidentally touching the keys
- additional Options:
- • screenstate_scaling V49 (Neo 17 r5): http://bit.ly/rd2yfk
- [S98system_tweak is already included & delivered with the kernel]
- Recommended additions:
- • Chainfire3d
- • [better but not full multitasking] V6 SuperCharger [memory script from #1 post only: http://forum.xda-developers.com/showpost.php?p=12058585&postcount=1] - no need for kickass script or other stuff - platypus scripts already have most / all of that and more stuff included <-- need feedback on stability, multi-tasking capability
- [Install script manager from the market, run it, navigate to the script on your sdcard,
- select the script, tick "run as root", press run. It will ask for user input after starting.
- Hold down left soft key to bring up the keyboard, type in 0 and press return.
- Next time it asks for input type in 9, press return, then 17 next time. Done.]
- • Auto Memory Manager [similar what V6 SuperCharger does] here you can set to have multitasking
- or the system to aggressively free memory
- • (for OC/UV): Voltage Control, Pimp my CPU, Control Freak, etc.
- • for monitoring the system and apps going crazy: Usage Timelines
- • for modem/wifi driver stability: speedtest.net <-- run speedtest & watch if phone reboots during upload phase
- • OC/UV stability: run mobo player or any other video player with HD videos for +15 minutes (in software mode)
- • CPU Spy: for Frequency & usage statistics of the cpu
- • Screen Filter: for more advanced screen dimming
- • Voodoo Control: for awesome sound
- Feedback - and on stability testing:
- • run the app from "speedtest.net" a few time with different servers with 3G+data/wifi if possible
- if it does NOT reboot during upload phase it's a good start [modem driver wise]
- • some general phone stability: open up bit.ly (redirection) links via browser, watch youtube
- videos, flash content, etc. ; browsing on github.com
- • benchmarks (some mild stability & performance tests): gpubench, smart bench 2011, quadrant standard,
- antutu, an3dbenchmarkXL, nena mark (+ submit result on nenamark & browse results <-- that lead to reboots on pre-Neo kernels in the past)
- • opening up e.g. "advanced task killer" immediately after the bootup [with or without 1st locking of the screen via power button]
- • playing back a (HD) movie for at least 15 minutes [mainly for OC (overclock), UV (undervolt) stability]
- • latency & smoothness related: doodle dash, tap tap revenge 4, labyrinth lite, ...
