[DEV] Developer Alliance

All,
I decided to create an open thread for DEV's from both XDA and Android Forums and where ever else, so we can all communicate back and forth on CM products for our phones. Since I know we have many sister phones which all basically have the same hardware I think it's time we all come together to help one another. Here is the known list of our sister phones.
- Motorola TRIUMPH
- Huawei U9000 IDEOS X6
- Viewsonic Viewpad 4
- Cherry Mobile Magnum HD A400
- Spice CSL Mi 410 - Slim
- WellcoM A99
- CSL Blueberry Mi 410
- Olive Smart VS300
- Axioo Vigo 410
- Huawei Ascend X
To start off the thread I will be answering a question from
http://forum.xda-developers.com/showpost.php?p=31460961&postcount=51

X6 DEV's,
I see that rcset forked over our device files from MTDEV-CM10 right now rukin is using his own branch called rukin check in there for current updates, our main branch jellybean is still going through some growing pains. Also not sure if you guys have seen but QUALCOMM released updated egl drivers for Jelly Bean. For what it's worth I replaced all our Video drivers from QUALCOMM for CM9 with their ICS update for arm7 and it made a huge difference in performance. Our original egl drivers from CM9 came from edowar's github so it maybe worth to update all your CM9 ROM's and test that out. Just wanted to pass this on to all you devs. Since our phones are so similar I think it's worth the continued communication between devs

My pleasure
Yes our proximity sensor/light sensor seems to be working fine in CM9 for the Triumph, I have not tested this in CM10 yet. I notice it works as long as you turn it on by going to Settings < Display < Brightness and check mark "Automatic Brightness". Also while on a phone call when you pull the phone from your face the screen also turns on.
Based on edowar's github I see he is coping over the sensor file
https://github.com/edowar/android_device_fb0/blob/ICS/device_fb0.mk#L246
The other thing to look at is TickerGuy's original commit to android_frameworks_base for CM7
https://github.com/tickerguy/android_frameworks_base/commit/8e748c9a692eb82a9374af398ecea63c7b1944df
It looks like it was included in CM9 by matera
https://github.com/MTDEV-CM9R2/andr.../android/server/PowerManagerService.java#L315
Also the other thing you may need to do is hack on the kernel as well, here is Tickerguy's original commits for light sensor and changing the LUX values to handle the difference in direct sunlight outdoors and also the lower light of being inside.
https://github.com/tickerguy/WX_435_Kernel-Tickerguy/commit/cc6431239094150c6d4d854afcb47ff5a4c19d7c
These changes have also been included in our 2.6.32.59 kernel which Mantera patched for CM9/CM10
https://github.com/MTDEV-CM9/MTDEV-KERNEL-CM9/blob/ics/drivers/i2c/chips/ltr502als.c
As for the proximity sensor not working while on a phone call I patched this in our CM7 Kernel 2.6.32.9 from mantera
[urlhttps://github.com/MTDEV-KERNEL/MTDEV-KERNEL-CM7/commit/96f11d9478c8043095a8b77e20414d91dd2742ce[/url]
This is also patched in our current ICS kernel as well 2.6.32.59
https://github.com/MTDEV-KERNEL/MTDEV-KERNEL-CM9/blob/ics/drivers/input/evdev.c
If you have any other questions please feel free to use the thread

good to see triumph developer in here,,
i don't know there is will be a problem or not when triumph still using .32 kernel base and our gsm phone using .35 kernel in almost our lattest rom.. even we know our diferent is just in ril libs.. may be you can try to compile .35 kernel for triumph from TJ or EDOWAR source.. but you have to port andro-id rc3.nb0 first as base..
Sent from my FIH-FB0 using xda

Good day FIH-FB0 devs Sir g60 and Sir aben.
It seems like this is the first time the head devs of the GSM and CDMA units of FB0 come in contact.
Maybe you two should communicate often, but so as not to infringe your right of choice you are free to do otherwise. Just an unsolicited suggestion anyway.
I just would like to ask what is hacking a kernel, or parts of it, in the context of sir g60's post above?
I would like to compile kernels too.
Thanks.
(⊙o⊙)
---------- Post added at 12:34 PM ---------- Previous post was at 12:25 PM ----------
um, one more thing.
i think, in the spirit of a formidable alliance between GSM and CDMA devs, we should first be unanimous on what kernel version to put forward.
There are only two choices at the moment:
a. 2.6.32
b. 2.6.35
As the two of you are head devs, i would like to suggest that you two make a decision on this matter, but again feel free to do otherwise.
Thanks.

abenagiel, yes we have been working on the kernel source. Mantera was able to get it to boot once but as of right now it's not working. I updated all our kernel sources and newly modified build script today and set it up under a new organization https://github.com/MTDEV-KERNEL/

If you would like to get involved in modifying your kernel we have some instructions on setting up your build environment using Linux 10.04 at http://mtdev.us in the wiki area. Also you can download the build kernel script we have created at https://github.com/MTDEV-KERNEL/MTDEV-BUILD-KERNEL and then you can download your kernel by tjsyte at https://github.com/tjstyle/android_kernel_fih_msm7x30. Make sure to read the instructions in the README as you will need the config in the kernel directory.

Thanks sir g60.

I thinks g60madman you only should port recovery V5.0.0.2.7 when you want to use kernal V.35..

Just a hunch, was looking at your permissions for the kernel and while gps works for you, when we made changes based on your kernel permissions our GPS stopped working.

HEX-RAYS
Dev's I wanted to share a tool that has been helping us a bunch lately that I found here on xda
http://www.hex-rays.com/products/ida/support/download_demo.shtml
This tool allows you load lib files and finds which files should be associated with it. Recently in making changes to our CM7 ROM we have increased our egl from 11fps to 19fps by using the Sharp Gingerbread libs. Prior to this tool we where never able to use these libs as we didn't know which libs where dependent on others. Anyways I wanted to pass this along. Also while this it's listed as a demo version the demo portion only works on ARM technology so for us developers of Android this is basically a full version for us! It's nice to know that sometimes open source gets a break :laugh:

CM9 Major Improvements!
Dev's,
I have added in the Code Aurora Qualcomm libs which I found from TwistedUmbrella and also Lloir's git hubs. Here is the commit I added
https://github.com/MTDEV-CM9/vendor/commit/0970ca0a148088ffcb945549689d7cc317ebedbe
Disregard the first four files of the commit as they are Triumph specific files.
cm/prebuilt/common/bootanimation/vertical-480x800.zip - CM10 Boot animation
motorola/triumph/proprietary/hostapd - Triumph specific file
motorola/triumph/proprietary/hostapd_cli - Triumph specific file
motorola/triumph/proprietary/sensors.triumph.so - Triumph specific file
The remaining code, and lib's should do wonders for your CM9 ROM and really give it a face lift in terms of speed and overall performance!!!

Question
Hi to all
I have downloaded the 20121013 CM9 rom for motorola triumph.
Can I just replace the lib files of any of our cm9 roms from MT rom to improve performance.
If it is possible, which are the main lib files which I should replace?
Please help

If you look at the GitHub link I posted all the files are in the system folder. You can download the zip from GitHub and pull out all the files you need. If look at this file it will tell you which files you need and what folder they go into.
https://github.com/MTDEV-CM9/vendor/commit/0970ca0a148088ffcb945549689d7cc317ebedbe#L43R185
The way to read the XML is after the : it will tell you the folder
:/system/etc/firmware/a225_pfp.fw
So that says a22_pfp. fw goes in system/etc/firmware.
If you have further questions please feel free to post

Wi-Fi Hidden Network?
I was going to ask, do you guys have any issues with connecting to hidden networks with Wi-Fi? Just wanted to check, as I added in edowar's updated wi-fi settings and I can not connect to hidden wi-fi, just wanted to check.

[Dev] [JB/ICS] OC Engine for 2.6.39 Kernel

I got time today a little while to observe OC possibility, and attempted. I was in hurry and these days I dont much have time these days so I've not tested what I've writtten, but theoretically it should work without issues:
OC Engine For LG Optimus 2x For 2.6.39.x Kernel
*It's written for 1.2Ghz but it's easy to ramp up to 1.4/1.5 by observing codes.
Devs feel free to use ,
and rippers dont rip codes to represent it as yours.

*See attached patch file

Wow thank you so much.....will have a look at it right away......

But as Topo said, OC is flaky currently. Anything more than 1.2 GHz make phone hang. Need to find where did NVIDIA implemented code for making CPU stuck as half frequency if its OCed.

great can u share it so that people can test! i have all msot shure that audio bug is boatloader related so if some on can compile a cm10 from RC and apply the new bootloader for testing will be great!

bootloadr is not related with audio bug... and that will never be.
official leaked ics roms doesn't have audio bugs just because they are official p990 roms with the official p990 kernel from lg, i remind you that cm10 is using su660 kernel source, a not completely but strongly enough different phone.

v30c Kernel Compiled with Linaro

Hi Guys,
I have managed to compile our ICS kernel with Linaro 4.7 and make it bootable after too much trouble.....
The kernel is compiled with o3 optimization
Toolchain used from made by Christopher83
http://forum.xda-developers.com/showthread.php?t=2098133
The kernel is tested with Nooby's v30b repack....
The kernel is build from original source i.e it has the first LED not working issue during Boot....
I would like to hear if there's any improvements or its just the same....
It was learning experience for me build a kernel .....
I do not guarantee of providing timely improvements or etc
I do not have a github etc...
can someone help me with that....i want to start it from zero ....with original source and will put patches on it...
I am attaching the patch as a zip file,..is a normal zip file with all the code necessary to compile the kernel with linaro,,,
it also has code of rmcc patch

O3 and linaro equals hard to debug bugs and no performance improvements.

Can you make one kernel for ligux rom?

The O3 flag would not give much improvement over the O2 flag as the optimizations that are brought in are only applicable in a few places and the kernel isn't that computation heavy. I still want to see a O2 and Os comparison, but I don't have time to waste on things like that these days.
As for different tool chains. I have seen a benchmark sometime ago with different kernels compiled with different toolchains. The difference was marginal and seemed to differ with kernels as well as toolchains (Some toolchains just like and dislike some kernels) . Overall Code Sourcery's toolchain did best on average I think.

Hi guys i have provided the patch to compile kernel with linaro in my OP....
regarding performance i didn't observe anything...
2days ago i officially updated my phone from 2.2 to 4.0 v30c because i wanted all my apps preserved.....
and today i experience sdcard unmount....i didnt experience it with my kernel and nooby v30b repack...maybe because i had i freshly installed...not sure....
i have not yet tried my kernel with v30c....because i have yet to patch the bootlaoader and install cwm...as per another threads to do this,,,maybe i will plan to
do this this weekend,,,,

Oh ...i got my phone reset when did reboot in recovery without any recovery with anreboot...and lost all my phone data....all efforts gone to wain...now i have to root and install apps again
Also my ICS version show 30C-SEA and i am from India...

I flashed official v30c and experienc ed sd card unmount. ..then installed v30b unlocked loader ...then installed my kernel and have been testing it....no sd unmount and also frontkey leds works according to settings done.....
Those who still have unmount problem can try my kernel in OP if you are using v20 bootloader. ..and those who use unlocked v30 unlocked bootloader dont use the Kernel attached in OP otherwise bootloop..just reply to me and I will attach the new one....

Just a statement regarding kernel source: The Kernel Source is released for all at GITHUB repo given below. BUT Free software does NOT mean no work or time was spent working on it. A lot of my free time has gone into patching/testing this kernel/features integrated in this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source.
Thank you !

CM10-FXP215
Whats Working:
device boots
usb gadget works
adb works (in recovery)
display working though might need some fixing
buttons work in recovery
android OS boots (stock ROM)
touchscreen works
sim card is detected
physical buttons are working correctly (stock ROM)
bluetooth is working
Whats Not Working:
ROM (CM10-FXP215) gets stuck at boot animation, doesnt go past the animation
ROM (Stock ICS FW .587) screen doesnt refresh properly

Glad to see DoomLord back to dev the new kernel,
I'll be the tester!!!

Nice DoomLord..
Hope Wedgess or Rachit can do something about this, n give our device something new...
Coz I'm just a noob user .

Real good stuff, exciting development going on for our old devices. I can be a tester for Anzu/Ayame if you need!

[Dev][Experimantal][Kernel][ION] nAa-ION Kernel

This is Strictly Development i u know something plz share if don't then be slient
What is ION .?
Noob way :- It makes things awsome -by lauppenstepperwolf
there is awsome explaination on LX git Wiki
LX said:
#### What is Shared Memory?
Memory is usually private; an app takes a chunk and nothing else can access it.
Sometimes, it makes sense to share memory between processes; for example, an app writes to the screen buffer, while the gfx driver reads that same buffer to put it on the screen. You need a special memory system for that.
####PMEM vs. ION
Back with Gingerbread, every ARM chip maker (Qualcomm, TI, nVidia, Samsung, more?) had their own way of doing shared memory. The Qualcomm way was a system called **PMEM**.
Problem: when a vendor sells a chip to Sony and Samsung, he needs to write two drivers, one for each shared memory system.
To reduce maintenance efforts, Google introduced **ION**, a unified shared memory system, that all vendors use since ICS
Problem: from ICS forward, Qualcomm only provides graphics drivers for ION. PMEM is obsolete.
For a while, stuff still worked, but it is getting worse for us - see the Google Maps app for example.
####Move to ION
An option is to rework the kernel, replace the PMEM system with ION, and replace the old PMEM drivers with newer ION drivers. A common problem on several old devices is, that the camera chip is non-standard, and Sony (Samsung, HTC) never wrote ION drivers for the old cameras. Moving to ION then means you lose the camera completely.
A new solution is to move the kernel to ION, but have a PMEM system on top of ION so that the old camera libs can connect to it. As far as I know, this was pioneered by the Dev_Connection team that maintains the Samsung S+ i9001 (great team, hats off to Christopher83 especially).
Another implementation of an ION/PMEM hybrid was made by galaxyfreak for the HTC Explorer (Pico).
The i9001 and the Pico have similar hardware to our 2011 Xperias (2011, MSM, 512MB RAM, similar specs).
Feedback for the ION builds is very positive. Performance is good and it solves some graphics problems like the Google Maps flickering, and it solves the slow browser.
####ION on LegacyXperia
It would be the next big step after the 3.x kernel, but, it's a lot of work.
On the i9001, 8 devs work on 1 device, while on our side, 1 dev works on 8 devices.
The i9001 approach was to migrate 10.1 to ION, then 10.2, then 11; instead of directly doing 11-ION.

THIS IS A REWORK ON nAa-kernel to use ION but with no video recording support ... until mike does spread his awsome magic with his new scratch ported kernel...

Current Progress : Intial Pushes done "yay" lets hope it boots
NOTE :- We need your help , i m not able to do alone since i have very limited knowledge about kernels , Please forgive me if my coding somewhere wrong cause
ok so thank you i will post progress as we all get step further ,
thank you

offical
its offical jb kernel ?

Can you read? It's not even official. It could be also for CM11 since he mentioned browser lag, which is an existing bug in CM11.
To OP, I should be able to check the coding and whatnot. Only problem is I'm currently in the army and unable to access my computer on weekdays.

@n1kolaa i guess you can start work on this if you have time.. I have seen you working.. Seems a real genius can you?

I should also be able to check the code as I'm proficient in C++. Let me know where I can help out, it's a good initiative.

ION and PMEM should'nt be device specific, no ? Isn't the work done on i9001 reusable here ?
First it could be interesting to locate all patches applied on the kernel to implement the hybrid memory allocation.
Edit :
I suppose the kernel in question is this one :
https://github.com/AriesVE-DevCon-TEAM/samsung-kernel-msm7x30/tree/cm-11.0_ion_pmem_adsp

ion is different for every device i guess
Update :
finished initial kernel part (lets hope it boots know)

Well, that's still fine.. Mini you have for testing.. Give it a try, you never know what you can end up with, probably a working kernel with ion support.. :thumbup:

I think I can develop based on this. Is the ION kernel actually booting and working preperly etc. ?

i have completed allocation but that f**kin msmfb code is a heck since we are using drivers from 3.0 need a lot of work

Thanks for your work! I love KK rom and im wait ion kernel :thumbup:

To many 4.4 roms are coming out....in my opinion all kitkat devs should focus on just 2 roms and this really good kernel.
At least with 2 different 4.4 roms there is still competiton for improvement without scattering work to much.
A nicely developed kitkat will save out Arc from retirement.
Btw i was wondering, since HDMI sources for kitkat are not available, would it be possible to create-compile a MHL compatibility for our arc? so we can use MHL accessory instead of HDMI? Or a virtual machine on kitkat running the stock ICS HDMI feature?
I'm no dev so i have no idea how hard it could be.....just asking out of curiosity, many use hdmi on arc for movies or android desktop with OTG mouse and keyboard. Its really a pity we cannot make it work on 4.4 yet.

A better Kitkat .. lets summerize current kernel situation
1. nAa 3.4 full of hacks
2. using drivers and stuffs from 3.0.x
3. Stuck on Abandoned PMEM {with every increasing android version we are using patches more than before to maintain PMEM causing soo many graphic lags
4. msm_fb code /* lets not focus on it currently */
why this mess /* to bring 3.4 kernel faster */
i m trying on 3.0.x-nAa kernel cause it is Pure CAF and also mike is working on Pure CAF 3.4.x MHL enablin gis such a lot and lot of work we are not in fully stable stage to look at MHL and other workaround first..
our device is a 3 year old piece of hardware without camera and HDMI libs using outdated kernel and drivers what should be the main goal
1. To make kernel updated with current sources
2. then make things working
3. then wprkaround for all abandoned hardware(like HDMI)
hope u know why we are focus on kernels and roms know ... and to come at point of compeion in roms
there is no compeition we are not selling our products .. we are working cause we like it and more roms means more respect for developers who are working tirelessly on maintaining those roms @Marchinho6 please no these kinds of post ..!these will spam thread
