heyo
how hard would it be to introduce a keyboard driver into for-next from dwalkers kernel branch?
https://www.codeaurora.org/gitweb/quic/kernel/?p=dwalker/linux-msm.git;a=shortlog;h=refs/heads/for-next
Would be cool, to have such a thing, then we would already have basic functionality needed to debug.
(dmesg from terminal and so on)

Matrix driver should be capable of doing that... and look into
staging, IIRC the driver is there.

Hi
Following thing:
I've now imported board-trout-keypad.c from android kernel
and modded the includepaths to make it build.
It also shows me over already running usb ethernet
over dmesg, that the GPIO matrix gets loaded but.
Following occurs:
--------dmesg--------
[   24.800000] gpiomatrix: set_irq_wake failed for input 42, irq 106
[   24.810000] gpiomatrix: set_irq_wake failed for input 41, irq 105
[   24.810000] gpiomatrix: set_irq_wake failed for input 40, irq 104
[   24.820000] gpiomatrix: set_irq_wake failed for input 39, irq 103
[   24.830000] gpiomatrix: set_irq_wake failed for input 38, irq 102
[   24.840000] gpiomatrix: set_irq_wake failed for input 37, irq 101
[   24.850000] gpiomatrix: set_irq_wake failed for input 36, irq 100
[   24.860000] GPIO Matrix Keypad Driver: Start keypad matrix for trout-keypad-qwertz in interrupt mode
[   24.870000] setting trigger mode 3 for irq 84 failed (msm_gpio_irq_set_type+0x0/0x118)
[   24.880000] gpio_event_input_request_irqs: request_irq failed for input 20, irq 84
[   24.890000] GPIO Input Driver: Start gpio inputs for trout-keypad-qwertz in polling mode
[   24.900000] GPIO Input Driver: Start gpio inputs for trout-keypad-qwertz in polling mode
[   24.910000] input: trout-keypad-qwertz as /devices/virtual/input/input0
------------------------
And as soon as I try to type something, the kernel totaly freezes.

Any idea?

best regards

You're using an older submission of gpiolib which doesn't support 
dual-edge IRQs.  That one has been scrapped in favor of the one from 
android's 2.6.35-wip branch. It hasn't been accepted yet, and is 
currently being discussed on the mailing lists.  If you search the 
mailing list archives from the past two weeks you'll find the patches.

Thx a lot!
I'll try it.
With keyboard+touchscreen+wheel and usbethernet I'll have something
which will GNUtoo to help me port the rest of the drivers I guess ^_^

big thanks and best regards
