[KERNEL] Franco Kernel-R21 [GPL] [16.10.2012]

10 octobre 2012 - R20 :

* GPU overclock interface. Now you're able to choose which frequency you want your GPU to run:
To check the frequencies just do this: cat sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
The default clocks are: 416 416 416 380 332 285 234.
To change to other clocks just do this: echo X X X 380 332 285 234 > sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
Substitute the X with 484, 520, 550, 600 or 700 if you'd like. Be careful that on higher clocks the device might get extremely hot and unstable. You're on your own.
* Added interface for you to choose which max frequency you want the companion core to run:
echo X > sys/devices/system/cpu/cpu0/cpufreq/cpu_lp_max
substitute the X with 100, 200, 300, 400 or 500. 500 is the default value.
* Added some custom driver changes to lowmemorykiller to force the device to have at least roughly 250-300 mb ram free - we don't want the device to run out of memory and we know how memory hog Sense is.
* Fixed CPU voltage interface with the correct values


20 septembre 2012 - R18 :

* Add back UV interface
* Refactored CPU frequency table: now it goes from 100Mhz to 1500Mhz in 100Mhz increments
* Adjusted memory bandwidth according to the new frequency table
* Tweak ondemand governor sampling time - now its the same as the cpu frequency transition latency
* Now all cores scale to 1500Mhz - previously single core mode scaled to 1500Mhz and when in multi-core it scaled to 1400Mhz. I think faux discovered this fix, so if he did, credits to him


13 septembre 2012 - R17 :

-Complete rebase into the new 2.17.401.2 sources


17 août 2012 - R15 :

-2.17 ramdisk and updated modules
-Wi-Fi should be working correctly now with no issues.


08 août 2012 - R13 :

* Merge latest HTC One X sources
* Fixed lots of HTC derps again in the newer source merge
* Some performance improvements on the ramdisk


30 juin 2012 - R12 :

* Attempt to fix most of the screen flicker. Like I said on the previous post its mostly fixed but its still partly visible on the lowest brightness. This is what I can see on my device, but there are 6 or 7 different panels around so I can't predict whats going to happen with all the users
* Enable fsync() calls back to the tree. If you enjoyed the extra IO speed I created a module_param where you can enable/disable fsync whenever you want (echo N to disable).: echo Y > /sys/module/sync/parameters/fsync_enabled
* Revert one of my previous cleanup patches that was causing some extra mAh usage during idle
* Some ramdisk tweaks


19 juin 2012 - R11 :

* Decrease minimum allowed UV from 600 5o 500mV
* Lots of cleanups to cpu-tegra.c and cpu-tegra3.c routines - HTC and NVIDIA need new engineers...
* A little cleanup to tegra3_clocks.c
* Another cleanup to Ondemand governor to simplify their derp code
* Add a new debug line during the undervolt routine for easy check if the voltages were really applied to the dvfs struct - check it via dmesg
* Charging should now be faster


15 juin 2012 - R10 :

* Add userspace voltage control. You can control the voltages via my own app or via terminal commands


02 juin 2012 - R9 :

* Revert back to stock Ondemand because I wanted to enable Two-phase algorithm that will possibly increase battery life (thats the goal for the algorithm)
* Decreased Ondemand up_threshold from 95% to 90%
* A little Ondemand tweak explained ici
* Cleanup of some of cpu-tegra.c routines explained ici
* smp.c: fix ARM RCU stalls
* A little patch to nohz from 3.0.31
* Little config cleanup


30 mai 2012 - R8 :

* Fix shutdown bug where it restarted instead of shutting off
* Re-worked baseband-xmn-power2.c cleanup - now airplane doesn't restart the device and the odd signal issues should be fixed
* Re-worked tegra_aic3008.c (responsible for the sound) and now listening to music should use less power (not confirmed, just an assumption)
* One or two extra cleanups


30 mai 2012 - R7 :

* I present you the first HTC One X completely warning/section mismatch/error free with over 100 patches (maybe more) where I cleaned all HTC's derp. Check my repository to see what I've been doing


27 mai 2012 - R6 :

* Some fixes from TripNRaVeR - awesome job be sure to send him a beer or two
* Lots of warnings, ISO C90 warnings, unused variables and other ton of fixes on top of HTC source (that is bloody derped)
* All the fixes are visible on my github repository


23 mai 2012 - R5 :

* Ramdisk rebased to stock 1.29.401.11 (it should boot on every rom now)
* Added native init.d support for the ramdisk
* Added previous ramdisk optimizations
* Enable ARCH_POWER to use arm_cpu_topology power management features.
* Added 18 kernel patches from NVIDIA


21 mai 2012 - R4 :

* Proper compiler flags (I accidentally built for cortex-a8 last build)
* Allow CPU-supported unaligned accesses - should give a tiny bit of extra performance
* Remove htc_print_active_wake_locks
* Remove HTC pokecpu
* Remove htc_util
* Fix ARM: Move leds idle start/stop calls to idle notifiers from previous process.c cleanup
* cpufreq: ISO C90 forbids mixed declarations and code - from TripNRaVer
* Revert "Decrease minimum VDD allowed for CPU from 850mV to 800mV." - I believe this was causing the extra screen flicker on lowest brightness and some users report of stuttering music while screen off
* CFS scheduler tweaks on the ramdisk for maximum UI responsiveness and smoothness - if you repack this kernel for other ramdisks you'll lose this tweaks
* Some config cleanups for better speed

This is a 1.29.401.7 ramdisk so you'll most likely have to repack it if you're running a 1.29.401.11 rom, so don't bother crying at me for non-booting issues.


16 mai 2012 - R3 :

-More fix-ups from showp1984 (danke you)
-Move x86_64 idle notifiers to generic - From Todd Poynor. This allows us to use the idle_notifiers interface for further patches
-Cleanup cpu_idle call from process.s
-Few compiler flags added
-config cleaned up a little bit
-Westwood+ TCP Congestion algorithm by default - should give an extra boost to internet speed and smoothness
-calibrate.c (loops_per_jiffy calculation file) updated to its latest version from Linux mainline
-A few ramdisk tweaks and cleanups


13 mai 2012 - R2 :

-Another round of fixes from riemervdzee (send him a beer sometime)
-Add ARM cpu topology definition
-Add Simple IO scheduler and made it default
-Ondemand governor updated to my 3.0.8 Galaxy Nexus branch
-Some MMC power management fixes
-Decrease minimum VDD allowed for CPU from 850mV to 800mV.
-Some PCIE patches from NVIDIA's repo
-Some other small patches available on my github


10 mai 2012 :

-Initial Release
