Gripping stuff guys. Keep up the excellent work, and we'll have multitouch on our beloved pulses :(

Well we don't know yet. Huawei included all this synaptics debug stuff and changed all the classes or whatever, so i'm guessing either we rewrite the multitouch code ... or rewrite the whole driver =/

Not to be rude or doubt your work or anything, but did you edit this by hand or just patch it?

Thats the first time i used Meld.

I'm used to patch them by hand - but I thought why not, just try it.

Sit down, relax, kick some big daddys' asses and let me compile the kernel :(

BTW if you guys want to test a custom boot.img, don't flash it to the device, but just boot it with this command:

fastboot-linux boot "...path/boot.img"
or if youre using windows 
fastboot-windows boot "...path/boot.img"

without ".

Okay, I'll patch it by hand.

Otherwise that won't work - I get too many errors.

But not until tomorrow.

I just don't have enough time today :(

I'll attach the logfile (with the patchfile in it :( )

And the boot.img :(

Haven't tested it yet, as my Ubuntu does not recognize my pulse :(

Greetings,

just got a restart when it's just about to go to homescreen.

I'm extremely interested in the work you guys are doing. I've given up this year so far (although I might restart when 2.1 is released, as my university's term will have finished around then).

Are you using fastboot to boot your image? If ubuntu is just reporting "waiting for device..." run fastboot as a superuser, that always fixed my problem.

You can have a look at the Logfile :(

I also asked Luke Hutchinson at twitter what he did to get MT working, but I haven't got an answer yet :(

Yap I'm using fastboot, but my device isn't even listed in lsusb :(

I don't have a clue why... works like a charm on win 7 RC...

You are using native Ubuntu, not in VB or similar, right? Maybe with another kernel? What do you see in dmesg after plugging in?

I'm using Ubuntu on my 2nd PC - i set this one up only for android developing :(

I'm using the standard kernel - I did not make an update.

I can't run dmesg right now, but in a few mins :(

BTW I now flashed the boot.img to my device - reboot -.-

But I noticed that i have a kernel.img with Touchscreen_Gesture=y and this one works fine.

forget it :(

Hmm...

It's getting even more and more and more complicated ...

I'm now again trying to compile the kernel with the other driver from Huawei (...tm1167 instead of tm1319).

- compiled without errors.

(using sysaptics_i2c_rmi_tm_1167 instead of synaptics_i2c_rmi_tm1319

and using cypress_byd_i2c_ts instead of cypress_cpt_i2c_ts)

But I guess that won't work either...

We'd have to edit the android source too for this to work...

But at least we have a kernel that supports multitouch.

Hey, I just noticed a very important mistake I made!

In the 2nd touchscreen driver from Huawei, the code for the second touch input is out-commented!

I'll now recompile the kernel.

Edit:

Okay, recompiled.

Here's the new kernel.

Can you flash this image as a boot image? (e.g. boot.img)

Nope, but I'll upload the boot.img too, if you want :(

But beware, if you flash that boot.img, you will end up in a boot-loop!

Edit:

Added boot.img to previous post.

Okay, guys.

Lets make a short summary:

What we have:

A kernel with multitouch.

We used therefore 2 drivers that Huawei fortunately delivered us.

(synaptics_i2c_rmi_tm1167 and cypress_byd_i2c_ts)

What we don'thave (yet):

A KeyInputQueue.java that receives the 2nd touch event.

the driver now returns

if (z) {

	input_report_abs(ts->input_dev, ABS_X, pos[0][0]);

	input_report_abs(ts->input_dev, ABS_Y, pos[0][1]);

}


input_report_abs(ts->input_dev, ABS_PRESSURE, z);

input_report_abs(ts->input_dev, ABS_TOOL_WIDTH, w);

input_report_key(ts->input_dev, BTN_TOUCH, finger);

finger2_pressed = finger > 1 && finger != 7;

input_report_key(ts->input_dev, BTN_2, finger2_pressed);


printk("ABS_X, pos[0][0] = %d\n"

	"ABS_Y, pos[0][1] = %d\n"

	"ABS_PRESSURE, z = %d\n"

	"ABS_TOOL_WIDTH, w = %d\n"

	"BTN_TOUCH, finger = %d\n"

	"BTN_2, finger2_pressed = %d\n"

	,pos[0][0], pos[0][1], z, w, finger, finger2_pressed);


if (finger2_pressed) {

	input_report_abs(ts->input_dev, ABS_HAT0X, pos[1][0]);

	input_report_abs(ts->input_dev, ABS_HAT0Y, pos[1][1]);

}

input_sync(ts->input_dev);[/code]




instead of


[code]input_report_abs(ts->input_dev, ABS_X, x);

input_report_abs(ts->input_dev, ABS_Y, 5880-y);

input_report_abs(ts->input_dev, ABS_PRESSURE, z);

input_report_abs(ts->input_dev, ABS_TOOL_WIDTH, w);

input_report_key(ts->input_dev, BTN_TOUCH, finger);

input_sync(ts->input_dev);

So, it should boot, even without a modified KeyInputQueue...
