I'm working for Freescale Semiconductor on the i.MX series linux BSP. Now we have android running well on i.MX515 platform, and hope to push android kernel repo into android.git.kernel.org. Then what's the process need us to follow? How reviews will be done? And what we should provide?

I use the following command to fetch all the source code of android
repo init -u git://android.git.kernel.org/platform/manifest.git repo sync
but I can not get platform/external/alsa-lib.git and platform/hardware/ alsa_sound.git
I don't know what's the rule for repo to fetch the code from http://android.git.kernel.org/

View 1 Replies View Relatedwhere I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?

View 2 Replies View RelatedI've got some trouble with the media backend (mostly Stagefrightplayer) in Android, and I'd like to understand why it throws the errors it does. The errors are usually device spesific, so debugging on an emulator wouldn't be sufficient.
Example:

Example 2:

I've also gotten the player to bork completely and spit out a traces.txt.
Is there a way to debug what's happening, just like I debug Java code?
I seek instructions for buiulding Android on the HTC Nexus. I have tried looking atthe OpenMoko ones, but could not find any useful guides. I have the Android SDK and Java JDK and this is it. All the guides on the Android site refer to installing Eclipse, which is for build Java apps so not a lot of use. Has anyone got some links? Please note that this is a question about building the kernel and the distribution around it. It is not about building applications for Android).

View 1 Replies View RelatedWhat sections of kernel code are changed for optimization of performance.
Like we can change
1) the minimum free memory that android need to keep free.
2) Rate of clearing cache
3)Advanced LMK- where we can kill more than one process at at time when memory scarcity occurs.
4) Reducing logging.
5) In framework we can change the oom_adj value of important processes.
6) Implement Zram for kernel.
7) change the minimum and maximum no of process for AMS.
I want to know all the changes that can be made into kernel or framework code to optimize performance. I also want to know how can we implement swapcache for android kernel. What changes do i need to make in the code.

For example, the arch/arm/mach-goldfish directory is not present, but devices from this directory are present in the kernel that the emulator boots.

View 3 Replies View RelatedWhy isn't Google playing nice with regards to the Linux Kernel Android code? Greg KH says the Android code is stagnant and as a result got removed recently: http://www.kroah.com/log/linux/android-kernel-problems.html
I know for a fact Greg KH bends over backwards to help Linux Kernel developers maintain their code, so hearing this news about the Android drivers being removed is very troubling. Hearing about all the hardware companies that now cannot get their own Android drivers into the main kernel is the worst of it. Google seems fairly evil lately, but everyone who should care (fellow Android developers, I'm looking at you) seems to just want to put their hands over their ears and sing "la la la la".
Android is not being handled in the true spirit of open source, and Greg KH's assessment of the situation is even more proof of that fact.

i am trying to look into android goldfish code and probably make some changes in it. As it is a long way to go for me i am actually unable to decide the tools that i need to set up.
