Panasonic Toughbook CF-29 Touch Screen

Nobles · 04-14-2007, 12:08 PM

Since this thread is getting extremely long and contains almost too much information now, could somebody post a detailed reply or a start a new thread with the complete how-to of how to get the touchscreens working with the newer 2.6 kernels. To keep things simple and make it easy for those trying to follow the instructions detailed here with varying Linux expertise, I would suggest pick a distribution, pick a toughbook model (preferrably either the CF-28 or CF-29 since those seem to be the models that require the most fooling around to get to work properly) and provide all the details (including where to get the latest patches) in one message much like James Jenkins did when he detailed how he got a CF-28 working with Slackware and the older 2.4 kernel.

Remember that evtouch X driver is recommended for use with touchscreens.

Thank you in advance.

Dtor, I used your CF-18 patches for kernel 2.6.18.8-0.1 (suse 10.2 kernel). There were errors with both, so I manually edited lifebook.c with the patch info. If you want to make any changes to the patches, are there any files you need from me such as my original lifebook.c or the .rej file?

I'm about to compile, wish me luck!

(PS for anyone compiling or new to compiling, when configuring, it is a good idea to start with the default config file located in /boot. It has the same configuration as the default kernel from the distro (assuming that most distros do this), so you won't miss any important areas that you may otherwise not notice)

I think that Nobles is correct that we need to start farming some of this information out of the thread, and his reasons were the same reasons that I did it myself. I certainly don't want to kill the thread or anything, as it has taken on it's own "life", and I think I would miss it.

So I created this Wiki, http://toughbooks.wikidot.com/ to that end. I would like to keep the thread going, but start to fill the Wiki up with completed content that was created as a result of the thread. This of course is NOT something that I want to do by myself, so I am asking if anyone is interested in helping. I have also activated the forums and setup some preliminary groups.

Let me know what you think, or if your interested in helping.

James

Why not use the LQ Wiki?

I just tried the fujitsu-serial-ts.patch against 2.6.18:

~/src/linux-source-2.6.18$ patch -bp1 <fujitsu-serial-ts.patch

Sorry for the delay. My CF-29 was with me in a sailboat at sea for the last two weeks. Internet access was infrequent and unreliable, and I was unwilling to risk messing it up.

Could you please patch again (with failures) and then manually add:

- to include/linux/serio.h

Code:

#define SERIO_FUJITSU  0x34

- to drivers/input/touchscreen/Makefile

Code:

obj-$(CONFIG_TOUCHSCREEN_FUJITSU)      += fujitsu_ts.o

This should allow us to work around differences between the latest trees and older one.

Thanks!

dtor · 04-15-2007, 12:13 PM

Because people use different distributions and older kernels it does not look like patches for lifebook module work well. Because of that I just uploaded the latest version of lifebook.c here:

http://www.kernel.org/pub/linux/kern...tor/lifebook.c

It should get out to the mirrors in the next hour or so. Please try downloading it and replacing /path/to/your/kernel/sources/drivers/input/mouse/lifebook.c
with this new file. If it gives you errors when recompiling please send me (dtor@insightbb.com) your original version of lifebook.c and I will patch it for you.

Thanks!

samstar · 04-15-2007, 02:00 PM

Well, I know I'm only making this thread larger, but two questions for dtor about recompiling.

First, does CONFIG_INPUT_TOUCHSCREEN need to be set, even though lifebook.c isn't a subset of it?

Second, do those edits to "include/linux/serio.h" and "drivers/input/touchscreen/Makefile" that you just posted need to be added as well, or is that just for the CF-29?

Just in - dtor, the lifebook.c file you linked to didn't help either. Got this message in kernel make:

No, you will only need it if you want to use fujitsu_ts module, not lifebook.

No, again these are for fujitsu_ts.

I believe I got your mail with original lifebook.c, I will try to patch it later tonight.

Received the following error building fujitsu_ts.c:

Please change it to read:

Code:

serio_register_driver(&fujitsu_drv);
return 0;

Also please change from:

Code:

static irqreturn_t fujitsu_interrupt(struct serio *serio,
               unsigned char data, unsigned int flags)

to

Code:

static irqreturn_t fujitsu_interrupt(struct serio *serio,
               unsigned char data, unsigned int flags,
               struct pt_regs *regs)

Note the addition of "struct pt_regs *regs" - newer kernels do not need this parameter but older ones do.

Azizcoos · 04-16-2007, 01:59 PM

Dmitry-
You have finally convinced me to switch to a new kernel.

What exact version should I get for maximum compatibility with your work?

dtor · 04-16-2007, 03:11 PM

I would just download 2.6.20.7 and use it. I just tried applying my patch to it, it gave me a bit of fuzz in Kconfig and serio.h files but otherwise built just fine.

Sorry it being such a pain for you guys.

samstar · 04-16-2007, 07:28 PM

Well, I patched both my suse's 2.6.18.8-0.1 kernel and the 2.6.20.7 standard kernel on my CF-18, using the three patch files from dtor. Recompiling and booting, I have to report a complete success!

No fuzz or errors in patching, and touchpad and touchscreen availability upon booting. There wasn't even any need to calibrate the touchscreen.

Azizcoos · 04-17-2007, 10:45 AM

I fetched 2.6.20.7, the fujitsu_ts.patch applied cleanly. The new kernel is built and booted. But 8250 and 8250_pnp did not get built as modules. It appears that they are in the kernel. Loaded modules serport and fujitsu_ts.

Quote:

# inputattach -fjt /dev/ttyS1
inputattach: device initialization failed
(Same for all ttyS*)
# setserial -g /dev/ttyS*
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4

/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

ttyS0 is known to be the DB9 serial port.

I now have more items in /dev/input/ than with 2.6.18:
event0 event1 event2 event3 event4 event5 mice mouse0 ts0
(event3,4 and 5 are new)
Test results using od:
event0 - keyboard
event1 - unknown/no response
event2 - touchpad
event3 - unknown/no response
event4 - unknown/no response
event5 - unknown/no response
mice - touchpad
mouse0 - touchpad
ts0 - touchpad

But still no output from the CF-29 touchscreen. Back to lifebook.c?

dtor · 04-17-2007, 11:46 AM

Coudl you try doing

setserial /dev/ttyS1 -v autoconfig
setserial /dev/ttyS2 -v autoconfig
.. etc?

Also, could you please send me your dmesg to dtor@insightbb.com? And dump of /proc/acpi/dsdt? Thanks!
