[Kernel Source] ToAsTcfh-Eclair-2.6.27 {Updated- Apr30, 2010} Murder-Kernel

this is my 2.6.27 source for eclair builds of android. this has been a long time project with lots of help from some great friends. i consider this a community kernel so all are welcomed to it, to use in their builds or what not. all thats asked is for all who use it, to give credit for using this source. just as u would for using anyone elses work. thats just to be fair to those who help maintain this kernel.
thanx:
maejrep

Good job Hopefully these fixes make it into all the awesome ROMs out there (yours included)

So this is the much anticipated OpenGL and Multitouch?

I actually grabbed the source from github /jhansche/htc-2.6.27-heroc last night. Got it compiled and running and I have to say it works nicely. Loving the OpenGL, but especially the multi-touch!
You guys are awesome. Thank you for all your hard work!

Sure is. This is the code base that got me the highest-on-Hero-so-far 29.9fps bench on neocore that I posted a screenshot of in his thread.

Amazing work guys

damn it I really need to get a linux setup so I can compile the kernels. I WANT THIS!!!!!! AAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGG!

Hope this gets incorporated soon into the latest 2.0.1/2.1 AOSP ROMs...also is this compatible with Gumbo's Kernel?

i'm pretty sure that this is a kernel, so your question's a bit confusing. maybe i'm just delirious?

I know its a kernel dude....still it can get incorporated into those ROMs builds like everyone has been waiting to do so...
What I'm saying is that with this now the ROM makers can get OpenGL and Multitouch on their ROM releases, something everyone has been waiting for.

soooo who wants to be so nice as to compile this to zip so people can flash it

yes that is true but you also asked if it was compatable with gbhils kernel that is why it was a little confusing.

Yes, this codebase (the last few days' commits at least) will enable hw3d and multitouch, and can be applied to any .27 kernel that is based on the htc-heroc-2.6.27 code that HTC released (which I should hope is all of them )
And yes, any kernel can be integrated into a ROM, as long as the ROM doesn't rely on custom kernel changes (e.g., squashfs is not enabled in this codebase, but if the developer already has squashfs in his own kernel codebase, he can apply these latest commits to his code, and compile a new kernel with both squashfs and gl+multutouch support, if that's what his ROM requires)

Yea I'm no tech guy/developer...just asking if on a ROM a dev could include this as well as the ability to setcpu which is available by way of Gumbo's kernel.

You can't add just a kernel to an update.zip and flash it -- kernel gets combined into the boot.img, which is included in the update.zip for every ROM. boot.img also has the stuff that goes into / (like init.rc scripts), and so not every ROM will be compatible with the same boot.img, and you can't just flash a boot.img by itself via zip (you can via flash_image in recovery, but still, some ROMs require the boot.img that it was designed for, due to init ramdisk )
So, this is more something for the ROM developers and the not-so-faint of heart. In reality, it's not that hard to build the boot.img, and you can actually unzip your favorite ROM's zip, unpack the boot.img, then rebuild a new boot.img using that ROM's initrd and your own custom kernel, then flash just the boot.img using flash_image, and it won't even require a wipe. That's again assuming the ROM doesn't rely on anything custom in the kernel it was released with.

ok I see what you where asking now majrep already answered most of it but yeah I belive that they could get the setcpu thing going in this kernel.

2.6.37.4 Kernels?

I was wondering if any of the kernels in the development section are re-based when a new Linux kernel comes out?
I've noticed that in all the HTC Forums that kernel threads will list what version of the Linux kernel they were based on but not here in the Nexus S forums. Why not?
What kernel version does it say on your Settings->About Phone screen?

Uh.. the threads here do mention them. Not sure about all of them but Netarchy does
- Kernel base 2.6.35.11 (as of 1.2.3)

And honestly.. I can really care less about the kernel base numbers. They're just numbers, I care about performance and speed.

The newest kernal has the best speed (2.6.38)

And where's the source of that "kernal" (it's kernel) proving that its the best speed on the Nexus S? I'm not saying a kernel for another device because thats irrelevant. That's like saying Windows 7 SP1 is faster than Windows 7 SP0 on two different machines with different specifications.

Thank you very much for letting me know your kernel version. I checked that thread and I did find it listed. I'm just trying to understand why the Nexus S doesn't have their kernels based on the latest Linux version when the HTC phones seem to.
But there not just numbers it's improvements to the base code. That can improve performance among other things.

2.6.38 hasn't made it to an android phone as far as I know.
Here is why he is say it's the best speed. It has a big change that should improve performance across the board.

Here are the kernels I saw on the first 4 pages of development.
Honity - No mention in main post
Voodoo kernel from Supercurio - No mention in main post
Netarchy - 2.6.35.11
Trinity - No mention in main post
I don't own an Nexus S so I can't look for myself. I just wonder why there is no mention. When I see the kernel version tracked by other phones.
Here are some examples from other forums.
[Kernel] [.37.4] intersectRaven's Kernel
[KERNEL][AOSP] - Savaged-Zen [2.6.37.4
[Kernel] LeeDrOiD v2.2.8
[Kernel] 2.6.32.33

Is the Nexus S locked on a specific kernel version?
Are the developers not re-basing the kernels?

Hmm interesting point, i too am curious

in nexus one i used intersecraven 6.37.x kernels, i dont think the nexus one was based on the 6.37 when it came out the first time it had 6.32 kernels

Well the Nexus S official kernel version is 2.6.35.7. It's easy to merge the minor patches, but a major version jump to to .38 would require a lot of manual fixing of the kernel source code.

Changing major bases would require a lot of porting work, as many of the drivers required by the nexus s are not in the standard kernel by default.
It will probably be done eventually.

Thank you for your reply. So just to confirm there are no technical limitations (lack of drivers/files/etc..) that prevent someone from re-basing their kernel versions for the Nexus S?

[Q] Will we see linux 3.4 kernel in ICS roms ?

Today I saw they launched linux 3.4 with merged android code into it, which made me happy. And also I read that they fixed the powersaving problem since 3.1 to 3.3, so my question is the one above. Will chefs be able to "port" 3.4 kernel to ICS anytime sooner or later? I know I should wait and see, as it is a kernel that was just released, but I just want to know wether this is possible.

It will most likely be merged and release for our Sensation. That is usually what Faux and showp do.

Thanks for the info, I remembered in my old desire that for example there were no 2.6.35 kernels for gb, so I thought it would not be possible. Hope to see it sooner than later

[Q] Custom Kernel Dev for HOX?

Do we have any Kernel developers for our One X? I noticed the other One X has Kernel development and custom kernels. I thought you had to be s-off but apparently not. Kernels are pushed over through fastboot. Maybe i'm just too anxious

HTC hasn't released the source code yet for the AT&T and Rogers kernels
As soon as they do I along with others will get started developing some kernels

Great Thanks!

Can't wait. It will be nice to get some better governers and different i/o schedulers.

It is always nice to know their are Devs out there that know what they are doing with the kernel as it can make a difference in device performance and day to day usage.

[Q] ICS ROM / KERNEL ? Anything official / Information?

Hello, I have been doing some reading here as well I sit on IRC on the #skyrocket channel which is pretty quiet these days.
I am using TPC GB rom build with Da_G kernel, and so far (since november 2011) it has been solid.
I have tried alienROM for the ICS leak, but it is missing some kernel features I like, however is a decent ROM. I was wondering if there were any nice ROMs or Kernels for ICS yet, or are well all still waiting for samsung to release an official ICS build so proper kernels can be made. It has been quite awhile and are we even getting an official build for the I727R (Rogers)
I wanted to post here if that is OK because I have not been finding too many answers to what I am looking for. I am in no rush really, but wanted to start thinking about tweeking my phone. Would it be best to play with leaked builds or just wait till some official builds come out then wait and go from there. If anyone has suggestions that would be great.
Thank you for your time and comments.

Hi. All the roms you'll find here are decent and will each appeal to different people and their needs. I've found the latest SkyICS to be excellent in many ways. Try a few different ones to see what you like. Any will be better than stock GB.
As for kernels, there are a few out, but none will have all the features we like about a custom kernel until the official ICS is released because -as far as I know - the code for the kernel hasn't been released yet.
For example, we won't have overclocking until someone can tear into the official released kernel.
I am not a developer, so please, someone correct me if I'm wrong about this.

Without kernel source nothing can be done. No oc, no uv, no bln.

Thanks for the reply, I am on GB (not stock) running rom / kernel (4.3.5) just can't decide on what ICS I want to go with. So I will continue to read away

Yes. He posted that before the t989 source dropped. Cymbaline used fixes from that source. We also have instigatorx kernel for aosp based roms.
