Description:   Opened: 2008-03-25 14:32 0000 
Force feedback upload of effects through the event device (ioctl EVIOCSFF) is
not working in 32 bit apps like wine.
64 bit apps like fftest work.

This is due to the fact that struct ff_effect contains a pointer, resulting in
the structure having different sizes in 64 and 32 bit programs. This means that
the ioctl issued from 32 bit code isn't handled, because it has a different
number.

Proposed patch

This patch makes force feedback work in 32 bit apps for me.

Are you the author? Has this been submitted upstream?

------- Comment #3 From Adam Dawidowski 2008-03-25 19:11:24 0000 ------- 
Yes. No.

------- Comment #4 From Mike Pagano 2008-03-25 19:26:59 0000 ------- 
We typically only backport patches from the official upstream development
kernel tree.

http://dev.gentoo.org/~dsd/genpatches/faq.htm

Are your plans to submit this upstream?

------- Comment #5 From Adam Dawidowski 2008-03-25 21:12:49 0000 ------- 
It seems I don't have a choice ;]
I'll get on it right away.

------- Comment #6 From Mike Pagano 2008-04-11 15:30:44 0000 ------- 
Adam, did you have a chance/are you still planning on submitting this upstream?

------- Comment #7 From Adam Dawidowski 2008-04-13 13:18:09 0000 ------- 
I'm having trouble getting through to the devs.
I posted the patch to the linux-input list (this archive tells me that the mail
got through: http://article.gmane.org/gmane.linux.kernel.input/4493), but got
no reply. I then mailed Dmitry Torokhov, the maintainer of the input subsystem,
but also got no reply. I must be doing something wrong...

------- Comment #8 From Adam Dawidowski 2008-04-14 06:17:23 0000 ------- 
Nevermind, I got a response from Dmitry.

------- Comment #9 From Mike Pagano 2008-04-30 01:01:35 0000 ------- 
Adam,

Any movement on your patch from Dmitry?

------- Comment #10 From Adam Dawidowski 2008-05-03 08:59:26 0000 ------- 
Nope. Nothing on the list either. I'll poke Dmitry again.

------- Comment #11 From Adam Dawidowski 2008-05-12 17:41:42 0000 ------- 
Dmitry came up with a better patch and it should get commited Real Soon
Now(TM).

------- Comment #12 From Daniel Drake 2008-06-29 16:50:07 0000 ------- 
The patch got accepted into upstream input tree
http://git.kernel.org/?p=linux/kernel/git/dtor/input.git;a=commitdiff_plain;h=bb00421d9b684253468bf751e7ce0a4667b721e8
We'll include it in the next 2.6.25 release.

------- Comment #13 From Daniel Drake 2008-07-01 02:34:05 0000 ------- 
fixed in gentoo-sources-2.6.25-r6
