My kernel source

Definitions and Terms you need to know

Linux Android Kernel
Android's kernel is based on the Linux kernel and has further architecture changes by Google outside the typical Linux kernel development cycle.[57] Android does not have a native X Window System nor does it support the full set of standard GNU libraries, and this makes it difficult to port existing Linux applications or libraries to Android.[58]

Certain features that Google contributed back to the Linux kernel, notably a power management feature called wakelocks, were rejected by mainline kernel developers, partly because kernel maintainers felt that Google did not show any intent to maintain their own code.[59][60][61] Even though Google announced in April 2010 that they would hire two employees to work with the Linux kernel community,[62] Greg Kroah-Hartman, the current Linux kernel maintainer for the -stable branch, said in December 2010 that he was concerned that Google was no longer trying to get their code changes included in mainstream Linux.[60] Some Google Android developers hinted that "the Android team was getting fed up with the process", because they were a small team and had more urgent work to do on Android.[63]

However, in September 2010, Linux kernel developer Rafael J. Wysocki added a patch that improved the mainline Linux wakeup events framework. He said that Android device drivers that use wakelocks can now be easily merged into mainline Linux, but that Android's opportunistic suspend features should not be included in the mainline kernel.[64][65] In 2011 Linus Torvalds said that "eventually Android and Linux would come back to a common kernel, but it will probably not be for four to five years".[66]

In December 2011, Greg Kroah-Hartman announced the start of the Android Mainlining Project, which aims to put some Android drivers, patches and features back into the Linux kernel, starting in Linux 3.3.[67] further integration being expected for Linux Kernel 3.4.[68]

CIFS
(Common Internet File System) The file sharing protocol used in Windows. It evolved out of the SMB (Server Message Block) protocol in DOS, which is why the terms CIFS/SMB and SMB/CIFS are commonly used. The word "Internet" in CIFS does not refer to the global Internet but to generic internetworking. The term was coined in the 1996 time frame when Microsoft submitted CIFS to the IETF and before the global Internet had become mainstream. See file sharing protocol, SMB and Samba.

NLS UTF-8
UTF-8 allows you to work in a standards-compliant and internationally accepted multilingual environment, with a comparatively low data redundancy. UTF-8 is the preferred way for transmitting non-ASCII characters over the Internet, through Email, IRC or almost any other medium. Despite this, many people regard UTF-8 in online communication as abusive. It is always best to be aware of the attitude towards UTF-8 in a specific channel, mailing list or Usenet group before using non-ASCII UTF-8.

TUN
This allows you to access an openVPN network using your android device.

Kineto gan
this driver allows you to let your android device make phone calls over VOIP network. (Tmobile currently uses this feature)

Kernel Governors

Ondemand
This governor has a hair trigger for boosting clockspeed to the maximum speed set by the user. If the CPU load placed by the user abates, the OnDemand governor will slowly step back down through the kernel's frequency steppings until it settles at the lowest possible frequency, or the user executes another task to demand a ramp.

OnDemand has excellent interface fluidity because of its high-frequency bias, but it can also have a relatively negative effect on battery life versus other governors. OnDemand is commonly chosen by smartphone manufacturers because it is well-tested, reliable, and virtually guarantees the smoothest possible performance for the phone. This is so because users are vastly more likely to bitch about performance than they are the few hours of extra battery life another governor could have granted them.

This final fact is important to know before you read about the Interactive governor: OnDemand scales its clockspeed in a work queue context. In other words, once the task that triggered the clockspeed ramp is finished, OnDemand will attempt to move the clockspeed back to minimum. If the user executes another task that triggers OnDemand's ramp, the clockspeed will bounce from minimum to maximum. This can happen especially frequently if the user is multi-tasking. This, too, has negative implications for battery life.

Performance Governor
This locks the phone's CPU at maximum frequency. While this may sound like an ugly idea, there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle. Race-to-idle is the process by which a phone completes a given task, such as syncing email, and returns the CPU to the extremely efficient low-power state. This still requires extensive testing, and a kernel that properly implements a given CPU's C-states (low power states).

Powersave Governor
The opposite of the Performance governor, the Powersave governor locks the CPU frequency at the lowest frequency set by the user.

Conservative Governor
This biases the phone to prefer the lowest possible clockspeed as often as possible. In other words, a larger and more persistent load must be placed on the CPU before the conservative governor will be prompted to raise the CPU clockspeed. Depending on how the developer has implemented this governor, and the minimum clockspeed chosen by the user, the conservative governor can introduce choppy performance. On the other hand, it can be good for battery life.

Userspace Governor
This governor, exceptionally rare for the world of mobile devices, allows any program executed by the user to set the CPU's operating frequency. This governor is more common amongst servers or desktop PCs where an application (like a power profile app) needs privileges to set the CPU clockspeed.

Interactive Governor
Much like the OnDemand governor, the Interactive governor dynamically scales CPU clockspeed in response to the workload placed on the CPU by the user. This is where the similarities end. Interactive is significantly more responsive than OnDemand, because it's faster at scaling to maximum frequency.

Unlike OnDemand, which you'll recall scales clockspeed in the context of a work queue, Interactive scales the clockspeed over the course of a timer set arbitrarily by the kernel developer. In other words, if an application demands a ramp to maximum clockspeed (by placing 100% load on the CPU), a user can execute another task before the governor starts reducing CPU frequency. This can eliminate the frequency bouncing discussed in the OnDemand section. Because of this timer, Interactive is also better prepared to utilize intermediate clockspeeds that fall between the minimum and maximum CPU frequencies. This is another pro-battery life benefit of Interactive.

However, because Interactive is permitted to spend more time at maximum frequency than OnDemand (for device performance reasons), the battery-saving benefits discussed above are effectively negated. Long story short, Interactive offers better performance than OnDemand (some say the best performance of any governor) and negligibly different battery life.

Interactive also makes the assumption that a user turning the screen on will shortly be followed by the user interacting with some application on their device. Because of this, screen on triggers a ramp to maximum clockspeed, followed by the timer behavior described above.

Lagfree
Lagfree is similar to ondemand. Main difference is it's optimization to become more battery friendly. Frequency is gracefully decreased and increased, unlike ondemand which jumps to 100% too often. Lagfree does not skip any frequency step while scaling up or down. Remember that if there's a requirement for sudden burst of power, lagfree can not satisfy that since it has to raise cpu through each higher frequency step from current. Some users report that video playback using lagfree stutters a little.

is it possible to fix link to newest kernel?

chenge from hthttp:// to http:// isn't enough

I think this one should do the trick ;)

Thx for the link


flashed, testetd seems to be fast with very similar benchmarks to bricked kernel:

Antutu benchmarked with Ordroid 1.82 and Rcmix 5.01 kernel:

Too early to say anything about battery and long term stability.

chenge from hthttp:// to http:// isn't enough

ok all the links should be working now.

[lulonen]

Unfortunately Ordroid rom isn't my ;-( but it's there:
http://forum.xda-developers.com/show....php?t=1551714

I got little better result with 5.1 than on 5.01 -> now 6546 points in antutu with ordroid 1.8.3.
GFX resuls are exactly the same. Did you OC@GPU?



I am also changing roms and karnels quickly but this kernel seems to be good for my battery so I am going to use it for a longer time.
Should I test it in any spesific situations?


btw. It would be nice to see at least RCMIX sense 4.0 rom with your super kernel...

[klquicksall]

New kernel up with some good changes.

Yes the gpu is OC. Yes were working on a rom to go with the kernel. Something should be out soon. The only situations you can test is like wifi calling. I'm with att so I can't test.
