Acer Liquid Kernel Source has arrived
and here it is on Acer's support pages for the Liquid

Acer Liquid Kernel Source

Just making a new thread so its easy to find by our wonderful developers  

[Mantisen]

Happy days for Liquid users I've been looking into getting my gf a Liquid (I have a Nexus One myself) since her LG KS20 WinMo phone is s*** and seeing how this should give ROM developing a fair boost it's probably decided now

hmm what this really means on simple words?

[maxisma]

Great, I'll try to compile it now.. Hopefully theres a good defaultconfig.

[chunga]

Fyi config.gz is a compressed configuration file for compiling the kernel.  It has what modules should be compiled in kernel, drivers, etc

[behnaam]

no defconfig is present under /arch/$ARCH in kernel source maxisma. Not even a arch/$ARCH folder is present, seems acer dont want us to build anything

[chingy1788]

So... Its over?

No 1GHz Liquid?

defconfig file that was generated is very poor and doesnt seem correct at all, time to contact acer again and ask what the hell they are doing.

and what about config.gz? did you manage to find it? i'm still looking for it.

I guess you could use /arch/arm/configs/acer-q8k-a1-dvt_defconfig or acer-q8k-a1-evt_defconfig (don't know the differences).

Compiled successfully with 1 GHz, but can't test atm as I'm busy. Will do tomorrow.
I'll include TUN, netfilter & compcache too
I'll try to port MT too..

guess you're right.. By the way dvt stands for desing verification testing, the testing stage that usually comes after evt (engineering v.t.) on early prototypes.

compiling now

So, according to the config, the Liquid uses an auo touchscreen. The driver is drivers/input/touchscreen/auo_ts.c

This driver doesn't support multitouch properly (looking at the synaptics driver in android 2.1, this shouldn't be too hard to implement), but it looks like the panel does (the driver just returns the mid point between the two touches), here's the interesting code:

	if (!finger2_pressed) {
		/* No multitouch -- force width to zero */;
		width = 0;
		x = coord[0][0];
		y = coord[0][1];
	} else {
		/* (x,y) coords for multitouch are at midpt between fingers */
		x = (coord[0][0] + coord[1][0]) / 2;
		y = (coord[0][1] + coord[1][1]) / 2;

		/* Report the width according to the abs distance of x-axis */
		width = abs((coord[0][0] - coord[1][0]));
	}

So is my assessment correct? I don't have a Liquid (thinking about getting one, but I'd like to have Android 2.1 and multitouch, and I might as well wait for the black version), so I can't test this, but could a dev see if the coordinates returned here are actually correct?

It is already available. I have a black version. I bought it from expansys.bg
