NEO 17 (r11 - codename Butterfly) changelog

NEO 17 (r11 - codename Butterfly) changelog [SGS/Telus, Captivate, Vibrant]

Changes (from r10):

• potential fix for SODs (sleep of death) while led-notification is occuring - thanks to pawitp !
• back to Neo 9 redux optimization flags - those should be more stable

NEO 17 (r10 - codename Butterfly) changelog [SGS/Telus, Captivate, Vibrant]

Changes (from r9 - 2nd testbuild):

• bumped RAM up to 348 MB (everything should still work, incl. Youtube HD recording)
• ported over smartass2 governor (super-smooth & battery-efficient, hopefully no issues anymore with getting stuck on high frequencies - unless due to system & broken apps)
• back to cm7 vanilla/stock yaffs2 driver - let's see if this fixes the discouraged random resets for few people (loss of contacts, apps gone, etc.)


NEO 17 (r9 - codename Butterfly) changelog [2nd testbuild - SGS/Telus, Captivate, Vibrant]

Changes (from r9 - 1st testbuild):

• fixed typos in system_tweak related to agps tweaks - thanks to DerTeufel for spotting them !
• new prebuilt driver to reflect changes to the kernel
• switched to floating-point optimizations + soft-float + neon [hardfloat seemed to have caused issues]
*crossing fingers* that it's more stable now
• like in the previous build: led-notifications included in the kernel by default - flavors: stock colors, voodoo color


NEO 17 (r9 - codename Butterfly) changelog [1st testbuild - SGS/Telus only]

Changes (from r8):

• changed back to platypus optimization flags (away from graphite flags - might have caused those SODs - sleep of death) [troubleshooting attempt]
• added network tweaks to all remaining networks (system_tweak)
• raised the number of events for GUI - potential smoother (system_tweak)
• some more s5p changes (cleanups)
• boost of in-call volume (kudos to efpophis)
• re-enabled setprop settings for improved battery runtime [testing + need feedback]

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


Troubleshooting:

• disabling led-notifications in CM7: "quiet hours" (http://wiki.cyanogenmod.com/wiki/CyanogenMod_Settings#Sound_settings)
• disabling led-notifications in MIUI: settings -> personal -> led-settings


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, ...
