franco.Kernel r14 – Sound Control V2 | ExFat

Direktlink zum XDA Thread


* IO patches all across the board
* Config stripped of debug for a lean kernel
* SLUB memory allocator
* CRC32 lib updated (important for some core features of the kernel)
* NTFS + NTFS write support – useful for USB OTG
* Module to change Wi-Fi power management policy on the fly (check second post)
* Module to enable/disable fsync() calls on the fly (second post)
* Sound Control V2 based on Supercurio Voodoo Sound – Volume Boost feature
* Much more to be seen on my repository
* This kernel is for Samsung roms only. No plans to make it work with AOSP or CM9

* Adjusted Mali DVFS up_thresholds – should be smoother
* Ajusted PegasusQ governor – up_threshold is back to default 85 and it scales much better beween intermediate frequencies
* ExFat modules should finally load and work (need testing please)
* Merged BFQ v4 IO scheduler and made it default (testing kernel with this new scheduler was very well received and got very good response by the community) – for more information why I added this check the Tuna thread
* Some CFS tweaks & patches
* Back to stock voltage tables
* Merged update4 sources from Samsung
* Other small CPU voltage changes

* Merged the latest hardcore MDNIE tweaks – less color saturation on Standard screen mode – thanks hardcore again!!
* Enabled TOUCH_BOOSTER again by default
* Added a module to enable/disable TOUCH_BOOSTER on demand – command available on the 2nd post
* MTP works on OSX again
* Pushed the latest version of the Low Memory Killer driver from the mainline kernel tree
* Some cleanups of legacy ****
* Lowered the default CPU voltages a little bit
* Smaller image since its compressed with XZ

* Add toggle to enable/disable thermal throttle (attention this might work or might not, I can’t make my device go hot enough for testing) – command’s in the second post
* Overclocked L2 bus from 133mhz to 160mhz
* Removed 1500mhz step – its useless and I don’t like it
* Increased USB charging from 600 to 800mAh
* Removed KSM
* Decrease busfreq OPP up_threshold from 30 to 20 – I’m not sure how big is the impact on performance, but at least in theory it will jump bus OPP’s on lesser system load, which in my opinion makes sense.
* Add a patch from Entropy512 as an attempt to decrease the wlan_rx_wake wakelock
* Some changes in the voltage table – please read this commit message:…c015525014d038
* Added sdwatcher binary to /sbin – this binary is special *buzzwords incoming* and will get rid of the fuse mounting and get rid of the /data/media symlink which causes excessive Media Scanning load – basically just mounts the internal sdcard as ext4. Battery life gets a nice boost using this binary. Instructions on how to use it at the second post. All credits go to Greg White, I did nothing but testing it for him

* Reverted my previous MDNIE tweak (didn’t work out as it should) and merge hardcore MDNIE tweaks, all credits go to him as it looks AWESOME

* Merged latest Samsung kernel sources
* Some MDNIE screen tweaks
* Disable Touch Booster from the touchscreen driver (will probably save some battery)
* Merged Mali platform rewrite patch from AndreiLux

* Added true init.d support. For init.d it uses a custom busybox bin version 1.18.1
* I’ve noticing that my SGS3 is really low on available RAM so I added some aggressive minfree and adj values
* I also added and enabled KSM (Kernel Samepage Merging) along with Memory Compation and Page Merging. All this buzz wordy **** will probably help on memory management in the long run, at least I felt a difference. I also don’t think it creates any extra overhead, which is nice
* Added back deadline IO as the default and did a few tweaks. To explain it better this is what I wrote in the commit description: deadline-iosched.c: we were already doing single batches so it makes sense to me to reduce the read/write submit times. Exynos runs with 200HZ so read submits occur 4 times every kernel tick and write submits occur 1 time per kernel tick (was 1 submit every 5 ticks before). This seems to have improved latency according to tests.
* I also merged a few patches to improve NOHZ and LOAD_AVG routines in the main scheduler driver. It seems that the load accounts weren’t properly calculated in conjunction with the idle times of the cpus, so according to Peter Zijlstra, the original commit author, this fixes that problem.

* ExFAT modules are now being loaded
* Increased USB charging rate from 450 to 600
* Some little ramdisk tweaks

* Add toggle to turn on/off fsync: echo N > /sys/module/sync/parameters/fsync_enabled (it’s enabled by default which means that enabled = less IO speed while having data integrity; disabled = more IO throughput but less data integrity)
* Add 1,5Ghz step – thanks to gokhanmoral because he found out where Samsung locked the max allowed frequency
* Compiled with -ffast-math
* Some ramdisk tweaks and adjustments
* Some config cleanups

* Back to Tree RCU instead of jRCU – Tree RCU coupled with RCU_BOOST brings the A game back to the field. It gives more CPU throughput and thus more performance than jRCU. It will be more stable (I think jRCU *could* be causing some weird instability when gaming)
* Lots of .config cleanups for a better end-user experience
* Lots of ramdisk tweaks and fix-ups for better experience
* Now it actually applies Simple IO scheduler as the default one (the ramdisk was enabling noop before)
* Some other minor differences and tweaks

* Added Simple IO scheduler by default
* Add Sound Control V2. Now with a proper sysfs interface that (I hope) isn’t intrusive to sound during calls (I tested a few calls and all was fine). Also will let you configure the strength of the volume boost. Huge props to Supercurio for the original work, I mostly ported the volume increase code to our device with a few modifications. Sysfs path its on the second post. Any encountered bug please provide useful feedback and not just „AMG NU WORK FIX NAO“.

* Added the first version of Sound Control based on Voodoo Sound by Supercurio: currently features a boosted sound volume and a DAC Direct tweak. Next iterations will feature user configurable options plus lots more options to choose from
* Reverted all the IO backports from 3.1 and 3.2 for stability purposes
* Decreased PegasusQ up_threshold from 85 to 80 for a little extra responsiveness
* Cleaned up .config even more, its getting leaner every release, which means more speed and better battery life
* Increase readahead value to 2048 from 1024
* Changed from noop IO scheduler to Deadline. Deadline is still my favorite and I actually think the fairness algorithm design is the best one for our ARM chips… noop is just TOO simple
* A nohz fix from 3.0.31
* Tweaked a few values of the LOAD_AVG CFS scheduler parameters
* More on my repo

* extFat module should now be working thanks to gokhanmoral
* Added SLQB memory allocator and made it default – seems to speed things up a little bit
* More config cleanups
* NTFS + NTFS write support – useful for USB OTG
* Compile with some arch flags for some extra tiny bits of performance
* CRC32 lib updated like its common on all my kernels
* I/O writeback functionality also updated to 3.2 kernel version just like its on my other kernels
* Tuned a little bit of the dirty_writeback values on the ramdisk
* Add module to change Wi-Fi power management policy on the fly: echo Y > /sys/module/dhd/parameters/wifi_pm (pass Y to enable and N to disable; its N by default). This option only appears after the wifi is activated
* More patches that are not relevant for the changelog but are visible on my repository

* Flash via ODIN or Mobile Odin.
