Patching, video and input

[Chris <ch...@st...>]

Hi,

     I recently obtained a Sun Type 4 keyboard and built a serial
interface for it. I started developing my own driver for it before
discovering this project. I've had a number of years userspace 
development, but I'm a complete newbie at kernel hacking so my
apologies for the dumb questions..

At present I am using a patched version of 2.4.5 (includes a number of
ac patches) Can I apply the LCP code without any nasty surprises being
likely?

Poking through the code, I've notices a number of video drivers. I'm
only really interested in getting my sun keyboard to work at the moment,
and not too keen on patching my nice stable kernel with more alpha code
that I absolutely need. Can I simply compile the sunkbd driver on its
own? I've noticed that a number of 2.4.5 drivers have been written by
the author of the sunkbd driver, and a quick look through the
appropriate sources doesn't seem to turn up too many obvious
differences. Do I actually need to apply the complete source patch just
to get that one driver to work?

Thanks for any feedback,

Chris

I haven't tried it with the ac patches. Their could be surprises. I hope
to in the coming weeks have it work again other trees (the mips and arm)
as well as Linus tree.

Yes. You don't need to apply the LCP patches to get your sun keyboard
working. What you do need is in the standard tree:

Enable input support.

Select Keyboard support
Select Joystick support
Select Event interface support

Then in the Joystick directory in character devices

Select Serial port input line discipline

Build everything and then build your sunkbd.o driver.

Do a if built all modular:

insmod input.o
insmod serio.o
insmod serport.o
insmod keybdev.o
insmod evdev.o
insmod sunkbd.o

Then run inputattach which is in our ruby/utils directory.

To test the device use evtest which is also in the directory.

If you need anything else just post to the list.

It all seems to work great, thanks.

Well I'd like to say thanks to you and everyone else involved in developing
this code, it's greatly appreciated!
