rk2918 uinput.ko for kernel 3.0.8

[tywerty]

Hi,

I have rk2918 devices without uinput.ko modules, can i use allwinner or AML8726 Modules instead?

Any input are appreciate.

Thanks

i not know if your device have already inside the uinput.ko, but you can't use the allwinner or AML8726 version.

your kernel is different. and you must compile it by yourself.

read the faq. nr 33 to understand if for sure you not have the uinput module.

rockchip in all rk3066 have already inside the uinput module, i not know in the rk2918.

what is your android device ?

this is the kernel:
https://github.com/DJNoXD/rockchip-kernel-rk2918

To enable uinput, after make menuconfig:

Device Drivers --->
Input Device Support --->
Miscellaneous devices --->
User level driver support

Thanks for your reply.

I checked uinput modules doesn't exist in my N90 device by android terminal as following procedure,

Open terminal emulator and look if you have /dev/uinput or /dev/input/uinput in this mode:

1) Open terminal emulator
2) su
3) cd /
4) cd dev
5) ls
read if you have /dev/uinput

or

1) Open terminal emulator
2) su
3) cd /
4) cd dev/input
5) ls
read if you have /dev/input/uinput

/dev/input/uinput is not a file in this test, you can't see this with a file manager, but you can see this with terminal emulator with the command su and ls.

I am a newbie and do not know how to compile the kernel.

Would you able to give me some guideline? Thanks so much.

[zulu99]

you can get any guide that you find in internet to compile a kernel for android. (is very simple and there are many guide)

the only differences is that when you do the commands "make menuconfig", you must select the uinput module as external module in this mode

Device Drivers --->
Input Device Support --->
Miscellaneous devices --->
User level driver support

Now i'm working in optimization and update of DroidMote, if i have time, i can see if i can compile it for you.

i need the vermagic of your kernel / module

get a generic module (search for a .ko file in your device), open it also in windows with a text editor, search the word vermagic and get the complete string vermagic=3.0.8 etc. etc.

Hi,

Thanks for your time and explanation.

I'm new to android system and really have no idea how to compile a kernel for android even it's simple.

I have find the info of vermagic as below and hope it's correct

vermagic=3.0.8+ preempt mod unload ARMv7

I really much appreciate your work if you possbile and have some free time slot to help to compile the kernel.

Many many thanks.

[zulu99]

Please try this and let me know if it work


rk2918 vermagic=3.0.8+ preempt mod_unload ARMv7

Hi Zulu99,

Thanks so much of your compile kernel. I have tested it but it doesn't work as procedures below :

Run Android Terminal :
1) SU
2) mount -o remount,rw /system
3) cp /mnt/sdcard/uinput.ko /system/lib/modules
4) chmod 644 /system/lib/modules/uinput.ko
5) mount -o remount,ro /system
6) insmod /system/lib/modules/uinput.ko

Error=> insmod: init_module '/system/lib/modules/uinput.ko' failed (Invalid argument)

Can you check above procedures is it correct or i missing some steps?

[zulu99]

Your procedure is correct, i think your board is different. I will retry to recompile for your specific board.

Please put for me in attachment your build.prop

And please make on your device in terminal emulator the command
uname -a

and in terminal emulator the command
dmesg
after you load the uinput.ko module posted by me.

Please send me this information in the next post.

I try to solve

Hi Zulu99,

Thanks for your prompt reply.

Hope above information will sufficient for you. Thanks Again

[zulu99]

in dmesg log, i not see error log about the uinput.ko


you must copy this log after you try to load the uinput module

after: insmod /system/lib/modules/uinput.ko

the problem is that i can't find the precise source code of the kernel of the N90 tablet.

the problem of many cheap chinese android device is this: violation of GPL

now i'm try with a very close kernel source code, but i need the information of the error after insmod.
