[patch 0/7] updates for xpad

[patch 0/7] updates for xpad

[Anssi Hannula]

What follows is a few patches for xpad fixing some issues, adding new
ids, and Brian's xbox360 wireless patch adapted for current xpad.c.

They are against current mm, i.e. 'match xbox 360 devices with
interface info' should be applied first.

[patch 1/7] xpad: fix dpad handling of unknown devices

[Anssi Hannula]

[-- Attachment #1: xpad-fix-unknown-dpad-handling.diff --]
[-- Type: text/plain, Size: 2006 bytes --]

For devices not specifically listed in xpad.c, xpad->dpad_mapping
is initially set to MAP_DPAD_UNKNOWN. In xpad_probe() it gets changed
to either MAP_DPAD_TO_BUTTONS or MAP_DPAD_TO_AXES, depending on the 
module parameter dpad_to_buttons.

However, MAP_DPAD_UNKNOWN is defined as -1, while the field is u8.
This results in actual value of 255, causing the MAP_DPAD_UNKNOWN
check in xpad_probe() to fail.
Fix that by defining MAP_DPAD_UNKNOWN as 2 instead.

Also, setting module parameter dpad_to_buttons to 1 should obviously
map dpad to buttons, while the default behaviour (0) should be to map
dpad to axes. However, dpad_to_buttons is directly assigned to
xpad->dpad_mapping, and as MAP_DPAD_TO_BUTTONS is 0, the actual
behaviour is reversed.
Fix that by negating dpad_to_buttons in assignment.

[patch 2/7] xpad: fix inverted Y and RY axes on xbox360 devices

[Anssi Hannula]

[-- Attachment #1: xpad-flip-xbox360-stick-y-axis.diff --]
[-- Type: text/plain, Size: 1421 bytes --]

The commit ae91d10aab2762f81733e9194cb56eff99c8d808 inverted Y and RY
axes so that up is positive and down is negative.
This is wrong, as axes on game controllers have up as negative per
convention. Also, even xpad itself reports HAT0X with up as negative.

Fix that by inverting them again.

[patch 2/7, rev2] xpad: fix inverted Y and RY axes

[Anssi Hannula]

The commit ae91d10aab2762f81733e9194cb56eff99c8d808 inverted Y and RY
axes on xbox360 so that up is positive and down is negative.
This is wrong, as axes on game controllers have up as negative per
convention. Also, even xpad itself reports HAT0X with up as negative.

Fix that by inverting them again.

Also, according to http://bugzilla.kernel.org/show_bug.cgi?id=10337 the
original xbox controllers also have the Y and RY axes inverted.
Fix that by inverting them as well.

[patch 4/7] xpad: do not report nonexistent buttons for xbox360

[Anssi Hannula]

[-- Attachment #1: xpad-do-not-report-nonexistent-buttons.diff --]
[-- Type: text/plain, Size: 2165 bytes --]

The buttons BTN_C and BTN_Z are only used in the original xbox
controller, not in xbox360 controller. Therefore only add them to
keybit when the controller is a non-360 one.

[patch 5/7] xpad: enable force feedback on xbox 360 controllers only

[Anssi Hannula]

[-- Attachment #1: xpad-fix-false-ev_ff-bit.diff --]
[-- Type: text/plain, Size: 1043 bytes --]

Commit 4994cd8dadcf9d484ab3ec19f3c7c7a4e5353c1c introduced a
regression which causes xpad to report force feedback cababilities
for non-360 controllers too, even while there is no actual support
for those.

Fix that by adding a check for XTYPE_XBOX360 to xpad_init_ff().

This is Brian's last patch from linux-input@ slightly adapted for
current xpad.c. I didn't see any further discussion, was there a
reason this wasn't applied last time?

I don't have the hardware to actually test it, though.

I applied everything to xpad branch of my tree. Please take a look and
see if I am missing anything and I will merge it into master.

Thank you.

They seem ok :)

BTW, "xpad - enable force feedback on xbox 360 controllers only" seems
to fix a null pointer dereference, I got a report from Edgar Simo that
he experienced system hang when trying to use force feedback with a
non-360 controller.

Maybe you should push it to the current stable trees as well?
