BFS 316

here it is, the BFS 316 scheduler patch
first i would like to say thanks to segway for posting the first backport (313) couldn't have done it without
then i want to say thanks to Coburn for adopting me into the Tattoo's world and letting me work with him
how to use it:
1. Get toolchains from CodeSourcery (http://www.codesourcery.com/sgpp/lite/arm)
2. Get kernel source code for tattoo from http://member.america.htc.com/downlo...-656120.tar.gz
3. Deploy toolchains and uncompress kernel source in dir "kernel_msm-htc"
4. Apply the attached patch
patch -p1 < BFS-316.patch
5. make ARCH=arm SUBARCH=arm CROSS_COMPILE=arm-eabi- msm7225_defconfig
(this will make the .config file)
6. make ARCH=arm SUBARCH=arm CROSS_COMPILE=arm-eabi- menuconfig
(this will let you configure the .config in the kernel, do only touch this if you have some idea of what you are doing!)
7. make -j 4 ARCH=arm SUBARCH=arm CROSS_COMPILE=arm-eabi-
(this will compile the kernel)
i will try to answer any questions as good as i can
and i will welcome anything else you would like to see in the future, just post some comments folks ;D
ps new patch is up, this one is working!

reserved for the future

Great.
But, for what can this be used?

Hi ralle.gade,
Great work. But you missed the most important file kernel/sched_bfs.c, dude.
I was very impressed on bfs-patched kernel running smoothly on our Tattoo. And I will try to patch my custom kernel with your patch if 'adb shell cmd' works normally, which couldn't work with segway's 313 patch. Would you mind?
EDIT:
'adb shell cmd' runs abnormally as segway's 313 patch, just a little pity.

Seems something cool!!
But i dont know whats this and what are the benefits of this...
Please help..

the new patch is up, this time everything should work!
could i get the d-info so i can try look at the problems with "adb shell cmd"

Hello, I'm interesed if there's a possibility to update Tattoo's kernel? Is the source code for kernel modules available?

i'm sorry bro! but the ****s at HTC can't get their ass up of the chair, meaning there's only the 2.6.29 kernel available from their site.
that doesn't mean we can't get a new version, at the time I'm working on getting 2.6.32 to work for the tattoo (but it's a pain in the ass when i don't even have a tattoo) :'(

But theoretically we could just apply HTC patches on a vanilla 2.6.33 kernel and get it working, couldn't we?

htc patches??? they don't release patches they only release the whole kernel but yes u can! that's what i'm doing right now

I didn't mean they release patches, but they add some to vanilla kernel for sure Thanks for the info, if you get success, please upload your patches so we can try to compile zen-kernel, git-kernel and so on

this is what htc added on top of the vanilla Linux 2.6.29 kernel
i made it into a patch, and by the way you can get a hard time opening it with a text editor as it is VERY BIG! cheers

Thanks. By the way, which encoding is the file? I cannot open it as utf8, and my text editor complains that it can't autodetect the encoding Anyway, i can't see any broken characters with utf8

i'm using ultraediter to open it, my normal text editer (gedit) compalins 2, but i just think it's because of the size and the amount of text! dude it's huge!

Oh, my bad, i was opening txt from zip archive. I unziped it and my KWrite opens it fast and smooth with utf8 now Going to try patching vanilla 2.6.29

good
please reply, and tell me if it works well

[DEVS] You too can build a CM-based AOSP ROM

Obviously, I am going to be cleaning up some bugs with the CM7 build...
But, for those of you who might be inclined to develop a CM-based AOSP ROM, feel free to check out my github source to see what's involved:
https://github.com/Hashcode
Or you can:
repo init -u https://[email protected]/Hashcode/cm4D3.git
repo sync
To pull the entire set of android files that I use for compiling the current build.
Please note that the Board Config is currently setup to generate Safestrap .zip files.

Great job
Thank you for everything you have done for the droid 3!

Is there a kitchen for DROID 3 roms. Running windows 7

You need to be running Linux to do this hardcore kind of stuff.

Like Ubuntu I had it set up in VB and detain. Was just wondering if there was some thing for Motorola roms out there. I have had HTC phones this my first moto with android on it.

And of course "gingerbread" could be "ics" if your excitement about being on the bleeding edge overrides what should be a fairly sensible fear reaction to the term "bleeding edge".
@Hashcode: You don't use your own ALSA repos? (Comparing with my own generated manifest for your project...)
Also, are you planning on pulling newer Gingerbread manifest changes into your tree? I noticed CyanogenMod have gained a u8150 device tree, and I happen to have one of those, but your manifest doesn't list it...
Ooops. I have a u8510. >_< But the question stands...

Thank you for pointing out that my repo init line was wrong. I fixed it for those that were having issues.
Also, for those watching my manifest for ICS, I'm getting an error when syncing:
error: revision refs/heads/master in manifests not found
I'm trying to fix that. Correction: Fixed it and double-checked with a repo sync.
Some quick answers:
- I tried to customize the alsa source to fix some of the audio issues. But it ended up being a bit more complex than just changing ALSA. Motorola added a layer into the audio system for handling HDMI audio and in call audio volume.
When you build stock AOSP Gingerbread using the alsa drivers, the libaudio.so file ends up being all of the ALSA calls. If you examine the libaudio from the D3, you'll see that it is nothing of the sort. It's the customized mixer lib for RDS voice and HDMI audio. There's another lib from the phone: libaudio_ext.so which ends up being the alsa calls.
All of which made customizing just the alsa code risky at best as the further away from the version of alsa that was used on the phone, the less likely that the custom libaudio would work.
I probably still have the unfinished hardware_alsa git out on github, but it's not active in the current build.
- I can occasionally check for updates to the CM7 manifest and add them, or if you fork the manifest and add it in there that works as well.
Side Note: I may need to pick your brain on an EGL 0x0500 erorr I'm getting in the ICS code. I'm fairly certain it's an enum value that our version of the PowerVR drivers aren't set to handle, but I'd like to confirm that for my troubleshooting. And it seems that you might have some knowledge in that area

Where/how does someone begin working on building a ROM once they've downloaded these files? I'd rather dive into code and learn Android rather than using a menu driven wizard. Is there a tutorial somewhere? What tools are needed?

Some, but probably not enough. I'm happy to look, but I'm actually moving internationally tomorrow so I may not have 'net access for a week or so. >_< (That's why I've been trying so hard to get backup working. ^_^)
Once I'm settled in I will probably use fdisk to repartition my device or have a poke at hacking sd-ext support into safestrap, so I can start playing with custom ROMs.
Did you see my safestrap-ME863 nandroid patch in the Safestrap thread, BTW? It's got a couple of TODOs, but seems safe and roughly correct to me. http://forum.xda-developers.com/showpost.php?p=19683372&postcount=249
It could also form the basis for detecting when /preinstall can't be used as safe-system although I didn't look to see if there's already code to do that.

Does anyone know of a site where I can peek at reference code for random things (Apps, Kernal etc.)? It'll make it easier to understand how the code works. I haven't look at any code yet so I don't even know what language apps and the os are programmed in. (Java, C, C++, Ruby)

Just pull down the repo as Hashcode describes in this thread - you'll have all of the Android source. To the best of my knowledge, it comprises of mostly C, C++, and Java, but there is probably a smathering of some other things like ASM, perl, BASH, etc.

Cyanogenmod 7 (Think Tank, in progress)

Hello All,
So I´m all sorts of new at developing for android, and I wanted to open up my thoughts and efforts to the community. I am trying to port CM 7, (eventually 9), and am using the CM Compiler that was developed by LithidCM. I´ve gotten everything up and running, now I just need to figure out how to set up the proper files from the Holiday itself. As I said, this is a work in progress, and any suggestions are very helpful. Right now, the stumbling block is setting up a Holiday/Raider/Vivid repo with the necessary compilation files.
Lets get cooking!
CMCompiler (All credit goes to Lithid CM) http://forum.xda-developers.com/showthread.php?t=1415661

+1 i would love to see cm7 or 9 on my vivid

That CMCompiler wont work for the Vivid
Sent from my SGH-T989 using Tapatalk

Not until there is either a CM repo for the Vivid or I can set up the correct files locally, then I can modify the script for it to look there, rather than the CM repo. Iḿ looking for ways to make it WORK, so anything to that end is appreciated. Either that or work on another method if it looks more promising. I have time, a machine, a device, some knowledge, and the desire, I just want to get together with some other people who can contribute a bit on the knowledge end to HELP get this up and running.

if you guys want i got a port booting with signal for the amaze almost same device

I too would love to see both CM7 and 9 on the Vivid, however from what i gather CMCompiler is not really going to be the way at it.
I follow alot of Team Haxsung and CM people and they all believe it to be not the best way to help the CM community, rather a way to re brand and take credit.
Further, CMCompiler requires there being a branch, which means that nightlies will be compiled quickly by build bots, if build bots are down or you want to make a nightly KANG you can install the dependencies via the CM wiki and build yourself, which might actually allow you to learn how to build and modify the source rather then having an application spit it out for you

AH! I have been using your repo as my source on CMC, but it fails each time because I´m missing some files. which files, well, that´s the step I´m at now. Im stoked your working on this. I´d like to learn how to do this on my own as well, then I´d be happy to put together a step by step from scratch for building from a fresh install of Ubuntu, I think it´s needed.

Ok we're just letting you know that the CMCompiler will not help. But try this.
http://forum.xda-developers.com/showthread.php?t=667298

My comment had no attitude as you speak of, like XAviierG i was just letting you know that if your intention is LEARNING the CMcompiler does not help with the process. Its an application that runs in a terminal window and you press numbers on screen to pull from the repos, again thats not learning and it wont help get the Vivid working any sooner.
I appropriate your eagerness to learn Linux, i am still learning alot aswell, and i too was excited when i read about the CMcompling application, however after reading about it and the stance of the dev teams i realized that its not the best for me and people looking to learn

CMC got me motivated to figure out how to get this working. Yes it´s a shortcut, no it doesn´t help anyone who can´t flash through rommanager already, and thus not us, right now. However, what gets people learning is a good thing, as far as I am concerned. I know far more about Linux now than I ever would have if it had worked beautifully from the start, including building everything through other means that it looks to do through invisible scripting.
As I said, I´m done talking about this.
Back on topic.
I am working on building a fresh CM7 Kernel through

make ARCH=arm CROSS_COMPILE=$CCOMPILER menuconfig

Tease: we have a successful booting CM9 from source
Current problem: the kernel we're using (stock from source) is missing the proper USB stack for ICS, as well as GSL changes, so we either have to fork toastcfh's kernel, or fix tiamat's kernel which currently doesn't boot.
However, we were able to get it to boot with a stock kernel built from source. Gfx are skewed, but touchscreen worked, and the colors were right-- so we're on to something at least.
Anyway, I'll be pushing what I have to my github as "holidayics" instead of "holiday" until it's ready for primetime. (@ http://github.com/thecubed )

4.9 Kernel

4.9 was released and Nexus 5 it's support by mainline kernel
http://www.phoronix.com/scan.php?page=news_item&px=Linux-4.9-ARM-Pull

Interesting. This might bring development back to the phone. Also 4.8 and 4.9 have some amazing features and speed improvements.

Will any dev merge and update our kernel? will this function with our android latest version?

No, it's probably not even functional in many aspects, there will be a lot of patching/fixing needed to get it to work.
There is already been discussed about his.

Yes, it's impossible use 4.9 without patch related to panel, exc exc

So what does exactly the "Nexus 5 support" on this kernel mean if you can't run Android on it without patching? Would it potentially help running Linux distros on our devices or?

There is support for the kernel, so yes, you could now run Arch, Debian, OpenWRT, or DD-WRT much more easily.
Android utilizes old libraries that are not compatible with new kernels (that's at least my understanding of the matter), so you would need to patch it to run a newer kernel, and that could only get you so far.
The newest kernel version that anyone had managed to boot Android with is the latest 4.4.x LTS release.
I wonder if someone could backport the necessary changes from 4.9 to the latest 4.4.x release though, that would already be something.

Thank you! I really like the concept of running *WRT on Nexus - I wonder how would functionality like network booting work like...
Could the mainline kernel also be used for other non-Android OSs like Ubuntu (Touch) or Sailfish OS?

I don't think so, as they rely on Android bits to work with the bootloader and recovery.
But perhaps there is a chance with the new OS that KDE are cooking, which is supposed to be completely independent of Android.

The 4.10 kernel brings in mainline support for the Nexus 6P and the Nexus 5X.
I wish that mainline support would arrive for the Nexus 4.

Update: Apparently Android 6.0.x and up can now utilize kernel 4.9.x.
As there is a build of Android 7.1.x for the x86 platform (I have no idea whether it is an official build of Android-x86, nor do I know the precise Android version, though) with a 4.9.x kernel (again, I have no idea precisely which version).
My source is a newly thread opened in the Remix OS forum, in which the OP asks for the possibility of updating the kernel in Remix OS, and mentions that he/she managed to boot it (only in debug mode, though) with the aforementioned kernel.

cat arch/arm/boot/zImage arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dtb > arch/arm/boot/zImage-dtb
Then i took twrp-3.0.3-0-hammerhead.img and extracted it with abootimg.
Changed the cmdline parameter for console to console=ttyMSM0,115200,n8
Took the new kernel and rebuild the recovery image to be my test image (just quick'n'dirty)
Then via adb:
reboot bootloader
... and afterwards injected the boot image (e.g.):
fastboot boot hammerhead-kernel4.img
See the attached file for the output.
This log was taken with a serial console cable attached to the earphone plug.

Hey folks!
I'm playing around with one of my nexus 5 devices for a while now... right now i got Maru OS installed and it's nice
But anyway this is another story.
Yeah i did!
Used this kernel (which is 4.9.27):
https://git.linaro.org/landing-team...rnel-debian-qcom-dragonboard410c-17.04.tar.gz
... and used Linaro GCC 4.8-2014.04 toolchain (had to use the 32Bit version here).
Then:
make qcom_defconfig
make
make qcom-msm8974-lge-nexus5-hammerhead.dtb

Wow, you are one of the coolest users on there! i doubt anyone could boot it up!
You rock! hope we can get a public release to test it out!

Hey that's amazing. I've been working on this too. So where exactly did you enter the command line parameter for console? Can you list out that command?

Thanks for appreciation, but what do you expect from "public release"?
As many other already posted here, this kernel is far away from the 3.4 Images for daily use.
So this is just for fun of course :angel:

Have a look at the tool abootimg.
You could use a bootimg.cfg fle and change the cmdline for your boot image individually.
E.g.:
Code:
bootsize = 0xe48800
pagesize = 0x800
kerneladdr = 0x8000
ramdiskaddr = 0x2900000
secondaddr = 0xf00000
tagsaddr = 0x2700000
name =
cmdline = console=ttyMSM0,115200,n8 androidboot.hardware=hammerhead user_debug=31 maxcpus=2 msm_watchdog_v2.enable=1 androidboot.selinux=permissive
The other parameters are fixed values for hammerhead... and the bootsize value depends on the size needed for your image.
In this case it's just the default value used for TWRP.
Then use the tool like this:
abootimg --create hammerhead-kernel4.img -f bootimg.cfg -k zImage-dtb -r initrd.img
Best regards,
scholbert

Wonderful! The heads-up I needed was the bootimg.cfg. Thanks a bunch. Also, is your ROM usable with this kernel?

No far away from any use together with a ROM or even anything the TWRP image uses inside.
No graphics... no usb...
This is just a proof of concept, playing around with the dts files and kernel. Nothing more.
If someone would create a console based ramdisk with some tools included, you may dig a little deeper into the soc or check which parts are responsive or not.

It has been quite some time.
Does anyone think that using PostMarketOS's kernel as a stepping stone may help get at least kernel 4.4 to a daily-driver ready status?
Update: Perhaps it would also be a good idea to use the Nexus 7 (2013)'s sources to try porting the newer kernel there to the Nexus 4 (as they share the same SOC).

From the logs, it looks like the reason the boot stops is because of init.rc errors. I might be able to help with that, but my nexus 5's battery is toast.
