Re: fftest: Force feedback doesn't work in native mode

I would suggest that you pick the latest kernel version available.

So, yesterday I did download and compile the 3.2.1 kernel, and also
installed it
successfully! But haven't tested the wheel yet.

On that machine I have a kernel version '3.0+dfp' which is a patched build
made when I was testing Michal's changes.

Would you please post the link of that patch here?
Reason - To make this wheel work on 10 computers, we'll have to compile the
kernel 10 times since the old configuration will have to be copied for
"make oldconfig".
That "may" result in errors in some cases. So, if I could get a patch
for kernel 3.1 (which
is by default on Suse 12.1), it may make my life easier.

It was like 8 months ago that I built it.... :-( The patches (if you need
them) are on the kernel mailing list.

I don't really understand why you would want to build seperately on each
machine, either grab a binary kernel RPM from the site I linked before ()
or use one machine to create your own kernel package (either RPM or just
TAR).

Does anyone really have machine specific builds these days (given disk
space is cheap and the modules system works really well)?

So, finally I tested this wheel on kernel 3.2.1, force feedback does
work indeed smoothly in the native mode.
Thanks to Simon for all the clues and patience.

:redface:

What I did was to copy the hid-lg4ff.c file on kernel 3.0.0 and change
that variable's name in the Kconfig file.
Recompiled the kernel successfully.

To my horror, after rebooting the recompiled kernel I found that
`fftest` doesn't produce the force feedback even in the "default"
mode. :banghead:

You have any idea what could I have messed up?
