[DEV] LANYU 910 / Airpaid RK2918 - Kernel / ICS WorkInProgress

Working on porting ICS to the Lanyu 910 / X10 Airpad MID-910. I think the kernel sources used for the Pascal2 could possibly work with the 910 after some config changes.
Basically with the 910 we have no stock kernel source available for reference, no stock configuration, no detailed hardware inside the device.. We know it uses the rk2918 rockchip and I know it uses the SWL-2480 / Marvel 8686, simply from observing the identifying markings on the chip. Other than that, all we know is that it uses a 2.6.32 kernel with android 2.3, has an unknown 7" capacitive touch screen, unknown camera, etc. In order for ICS to work with the 910 we'll have to use a 3.0.8+ kernel or backport all of the required components from 3.x to our working 2.6.32 sources -however we don't have the patched sources for the stock firmware, so we are better off to just use 3.0.8 kernel that the source is available for on many rk2918 devices - of course we'd have to make configuration changes to our specific hardware, and possibly patch the sources with modified/new source code for our specific hardware (if we can obtain it).
Pascal 2 has a realtek based wireless chipset.. 910 uses the SWL-2940 / Marvel 8686, the module for this is also included in the kernel sources. The 910 has an unknown touchscreen, so the kernel for the pascal2 may or may not work with the touch screen settings. It is quiet difficult to work on the kernel without in depth knowledge of all the hardware. The 910 has Lanyu printed on the motherboard, and I'm not successful in finding any detailed hardware information for the board on the 910.
Also I am concerned with the memory mappings since the 910 only has 512mb ram and the pascal2 has 1GB+
Really wish these Chinese tablet manufacturers would follow the rules of GPL and release their source code, it would help A LOT with getting ICS to work with the 910.
As far as the rockchip and the ICS rom that vurrut has put together, I am almost 100% sure that the system.img that he used will work with the 910 as long as I get a working 3.0.8 kernel for ICS reconfigured/recompiled and implement some changes in the boot.img for the init services relating to hardware.
If anyone has the X10 airpad (rk2918 based) or the Lanyu 910 and has some important information regarding the internal hardware, please contact me with details, as I can probably get a working kernel for our device in a matter of hours.
Needed:
Gsensor/Accelerometer MFG/Model
Input Keys Controller - MFG/Model
Battery Sensor Chip - MFG/Model
TouchScreen/Display - MFG/Model
Other mainboard chipsets - MFG/Model (excluding RK2918 Rockchip SoC)
It would be of much help if there was someone here knows the MFG/Model of any of the above hardware, and it would also be a great help if anyone knows what linux kernel drivers are used for any of the components inside the 910.
When I was working with the Kindle Fire kernel I had found a very helpful information page on the internal parts of the device, with very detailed information - it was really helpful. I know that with these generic Chinese tablets finding such info may be much more difficult due to lack of interest and lack of popularity when compared to major brand tablets such as the Kindle Fire - but if anyone out there has ran across similar information it would give us GREAT progress in developing an ICS ROM for the 910. Here is a link to the breakdown of components in the Kindle Fire:
http://www2.electronicproducts.com/Amazon_Kindle_Fire_D01400_Tablet-whatsinside_text-123.aspx
The thread to the ICS ROM for Pacal 2 (rk2918) device is here: http://forum.xda-developers.com/showthread.php?t=1734181
A big thanks to Vurrut for all of his work! Hopefully we can use parts of his ROM to get ICS running on our Lanyu/Airpad!

Pls open a terminal, type "dmesg" and upload the log. Then we will see
If you have luck your build has also the kernel config file. You will find it under /proc/config.gz.

Do you honestly think I would be working on a Linux kernel without a knowledge of the existence of dmesg or config.gz? Did you also forget to remind me of adb shell logcat -d >> logcat.log ?

Only partial information can be obtained in this manner as it will only show what device modules are loaded, the information I was wanting was precise model information of the chipsets used in the tablet. And the config for the stock kernel is not included in procfs anyway as the developers must have not said =Y to CONFIG_IKCONFIG

Mr. Oma, I am sorry but I think you may be in the wrong thread, the Lanyu 910 only shares one thing in common with the other common RK2918 based tablets, and that is the RK2918 its self, the rest of the hardware that makes up the full system is different on the 910/Airpad than the more popular tablets that are using the RK2918. For example you probably use a RTL based wifi chip in the config you are using also, where the 910/AP uses the SWL-2480 which uses a Marvel 8686 driver in the linux kernel or you can use the libertas driver in more recent kernels. What exactly is the config you pasted here from? At this point I know the internal hardware enough to get a proper config file for the 910/Airpad, however there are compile issues with certain components and without resolving the compile issues there is no kernel image going to be generated unless I disable the problems at hand in the config, if you want more up-to-date information then head over the the x10 forums and check the original thread for 910/AP kernel development: http://forums.x10.com/index.php?topic=27184.0

Have you seen this?
Here is another Tab using SWL-2480 (looks like an Aoson M12).
Here is another 3.0.8 source, originally from a Chinese Tab named Xinboa.
Maybe that helps.

I appreciate your effort in helping me find info, but I have already researched most the possibilities and am already aware of the sites you linked. The problems aren't finding hardware specs, the problem now is getting 3.0.8 sources to compile with the Airpads hardware selected in the configuration, as I posted in the x10 forum, it doesn't appear that any 3.0.8 kernels have been successfully compiled for other devices using the same board-config as the 910, in fact the link you specified with the swl-2480 is the only device that has similar hardware aside from the rk2918 that I have found. The wifi and audio both fail to compile with Ody.se sources. I have decided to put most of my work now into testing/development of Jelly Bean for the Acer Iconia Tab, as it doesn't seem that many others are interested in the 910/Airpad development. Thanks again

Ok.
Odys-Xpress sources? That's kernel 2.6.32.27, isn't it?
But try the sources from above link. Could search for that
A library for Marvell 8686 SDIO WLAN devices.
So far, the following modules have been verified:
(1) Samsung SWL-2480
(2) Azurewave AW-GH321
(3) USI WM-G-MR-09
(4) Murata SP-8HEP-P
I don't know if they will compile.

They won't compile with 4.2.0 or 4.4.0 arm eabi toolchain in 3.0.8 sources, i tried them, since 3.0.8 it has been replaced with libertas instead of mv8686, i've done looked into all of it man

I also tried gcc 4.6.2 and 4.6.3 natively setup with cross compile in Gentoo / Funtoo - I get the same same errors with the wifi and the audio as using the appropriate eabi-arm toolchains.. I tracked down the problems though, it is a dephell with major code changes in common headers. The headers that are included in the sources have changed from 2.6.32.27 and to 3.0.8 and porting everything up to current is quiet more code changes than I am willing to work on. Like I have said though, I am no longer working on this kernel for the generic devices 910/AP, I have more work on my slate now than I need working on the Acer Vangogh / Vendetta kernels for Jelly Bean to incorporate Tiny HAL and newer tegra changes keeping compatability with the only Acer source we have available. But at least I am not limited to products that aren't following the GPL appropriately, and the use of uncommon hardware that makes debugging damn near impossible. I almost have the Vangogh board and Acer specifics ported over to 3.1's grouper from the nexus project and it's much more smoother than working with that chinese developed tab

Ok, than have a good time!

Git repository for kernel

Created a git repository for the kernel for easier collaboration in the future, plus Acer's download site is pretty slow.
Link: https://github.com/pawitp/android_kernel_acer_t30
Compiler: Use gcc 4.6 from AOSP Jellybean prebuilts
Compiling
Code:
export ARCH="arm"
export CROSS_COMPILE="/path/to/arm-eabi-4.6/bin/arm-eabi-"
make picasso_mf_defconfig
make -j4 zImage modules
Then you can flash the zImage with the extracte stock ramdisk using fastboot
Code:
fastboot flash:raw boot /path/to/zImage /path/to/ramdisk.gz

the good one
Link: https://github.com/pawitp/android_kernel_acer_t30

Thanks, I changed the url but forgot to update it.

no trouble, just to help
hope that you'll have a working tab soon, we should set-up a petition online to badger Acer to get nvflash

Is the kernel published here the same as on acer's website?
Is the one published on the acer's website the same that runs on the A700/A701 tablets now in fw 15 and 17?
Did you find what locks the system remount in the sources, or that's something acer added after they've published the sourcecode to the website?

It's the source imported from Acer's source site, with modification as seen in the git history. I'm not aware of any new kernel release from Acer. The remount block is something not present in the source (which would be a violation of GPL on Acer's part).

Thanks for clarification.
In this post: http://forum.xda-developers.com/showpost.php?p=31105735&postcount=5 you say there is a kernel block.
I'm determined to have root with ability to remount (for adfree to work at least)
Any ideas how to proceed?

About Jelly Bean i don't know, but it must help to tune cpu governor (in default cpu works on deep sleep, 166 and 1001, but don't use 250 and 500), may be it help to solve the problems with proximity and light sensors... etc.
In theory you can take JB original sourses from Google and mediatek sources for ICS, and may be you can run JB from other device (for example last firmware from JY G2 MT6575)... But so far no one has yet tried to do it... Sorry for my English

Ok guys!i would appreciate it if you could solve the problem with governor!(ondemand mode 166,250,500,1000)!it works only 500-1000!A new custom rom maybe?thaks!

hi.. i'm already started make some modifications on ROM with other Brazilian DEV's for "Evertek S.A - SKMtek Genesis Tab GT7305"... we already found the source kernel from another Netbook or Development Board PC who uses the same SOC... but nothing already have been maked to kernel, we use the provided kernel from stock (Kernel 3.4.5+)... and about the ROM we already have two custom ROM's... One is Stock Modded (4.2.2) and another is KitKat Ported ROM from another Evertek Device... *Portuguese-Brazil Language Site/Forum
And we already make some modifications to this KK port...
- ROOT
- BusyBox
- Init.D support
- Build.Prop Mods
- SuperUser
- zipalign apps after boot
.. and other mods.
we already make too much on ROM but nothing about kernel... we want make a better kernel with optimizations and a better TCP/Clock Table, More Governors , More I/O Scheduler and maybe Overclock to 1600mhz to start after have a custom Kernel booting...
Now we need someone who understand about recovery's like CWM or TWRP and Kernel Compilation better than me to we can start make something awesome =D i think this can be used to another company's/Chinese tablets too, using the same SOC (WM8880) evidently... . . . (Found^^Working^^Recovery's)
i can't start testing here because if i flash this kernel using the Stock Recovery (WonderMedia Recovery tool) maybe i can possible brick my tablet... so if someone understand about CMW recovery to start would be nice =D

just a few Brazilian and Malasya Developers still make progress with this SoC... if you want to try install the custom ROM´s i have shared upper topic.. it will be by your won and I am not responsible for bricked devices...
i´m already started make progress with Custom Kernel but i need found the touch screen driver source and re-work the sound driver(Alsa Drivers...) and compile the recovery with kernel too.. to than have some trust on my work to flash it on tablet =#

meh, its my rom testing ground anyway not really worried .. i actually have the tablet connect directly from the battery wires(the battery removed) to the adapter(usb)... anything is better than nothing for the development hehe...wait by Malasya do u mean Malaysia? whos that developer lol..

i mean Malaysia.. the country... because i don't have found the real developer.. only the Facebook's group where it have been shared... i write too fast and don't check if i write it correct too...

i Already compile the kernel with CMW recovery and flashed on tablet ... but i need find the Touchpad driver to make he work properly... i stay getting some other minor issues on logcat/kmsg reports...
but i already test four touch drivers and anyone works... only OTG stay working.. that is the problem on developing the kernel without the official source release by the producer company... maybe i will need close this developing project because that =/

man... i just don't want blame anyone but... to we can do something to your tablet we need the kernel source and that don't stay open to developers... on this Chinese tablets we have some little configurations to can work with... but the custom kernel project i need to abandon for two reasons... first i don't have much time to can work to create a stable and functional custom kernel to everyone... second i don't have a kernel source compatible with tablets... what i found is from a electronics engineering Project computer Board ... and to it can fit on tablet is missing too much drivers compatibles with to can work smoothly and functional... someday if i found a new source maybe i can try comeback developer something to that =#

please continue developing this project
I use a genesis 7305 his kernel is very poorly optimized would like to make this usable tablet sorry for my bad English I use Google translator ;-;

2021... I tried to put a Chinese rom, but I brick the tablet, it only responds to fastboot, when I put the sudo command fastboot flash:raw boot uzImage.bin ramdisk.bin and plug in the charger and press power it appears a genesis screen.
