In linux/input.h each section's (e.g. ABS) FOO_MAX is the maximum FOO
value. Recent kernels define FOO_CNT as the maximum number of FOO there
will ever be. Hence using FOO_MAX to size the bit vectors representing
the capabilities of an evdev device is off by one.
Define FOO_CNT values for use with Linux kernels which lack them. Use
FOO_CNT whenever we need to know the number of bits needed -- usually to
calculate the number of longs needed.
When iterating over the values FOO_MAX still seems appropriate however
the loop test should include FOO_MAX rather than skip it.

NBITS really convers the number of bits passed as its argument
into a number of longs. This is somewhat atypical of many
function-like-macro names. Rename it to NLONGS.

If it's available report pressure as third valuator.
(Use xf86PostMotionEventP instead of the varargs wrapper.)

Good for filling up the device list without getting distracted by spurious

Discard all repeated events that come from the device. The server will handle
per-key autorepeat in software.

For keyboards, scroll events are reported by the kernel as EV_REL class events
of REL_WHEEL type. If, during probing, the device is found to support wheel
events, make sure it is set up as a pointing device, even if it doesn't have
buttons or doesn't report motion along the X and Y axis so that the scroll
events can be mapped to mouse wheel buttons (usually buttons 4 and 5).

We handle autorepeat in software due to per-key repeat and whatnot, so
disable the kernel's, which just interferes with ours.

Devices added that use the same min/maj as an already added device are ignored
by the driver. This way users can have an xorg.conf entry on
/dev/input/by-id/blahblah and not get the same device added by HAL.

Some devices require run-time axis calibration. We can't change the min/max
ranges once we've initialised the valuator structs though, so in-driver
run-time calibration is required.
If the property is set, the driver scales from the calibrated range to the
values reported to the X server (which then may scale to screen coordinates).
If the property is not set (i.e. zero items) no scaling is performed.

Three test devices provided:
btn0 .... Provides BTN_0, BTN_1, BTN_2 instead of BTN_LEFT, BTN_MIDDLE,
BTN_RIGHT.
abs ..... Provdes x/y absolute axes, jumps between 100/100 and 120/120.
absrel .. Provides relative x/y axes and absolute x/y axes at the same time.

Treat BTN_[0-2] as LMR buttons on devices that do not advertise BTN_LEFT,
BTN_MIDDLE, BTN_RIGHT (e.g. 3Dconnexion SpaceNavigator).
Otherwise, treat BTN_[0+n] as button 5+n. Note: This causes duplicate
mappings for BTN_0 + n and BTN_SIDE + n.
This also fixes a bug where we could end up with negative button numbers after
trying to map BTN_0.

This got broken in b0737bdbd1f6e601eb4984b6f4cb49279190984c, when the
EmuMBPreInit call was removed from EvdevOn. As a result, VT switching away and
back wouldn't restore the wakeup handlers and mouse button presses
disappeared.
|
|
If min_x/y was not equal to 0, the inverted calculated range was off and leads
to inaccessible or out-of-range areas.
|
|
If we're forcing MB emulation behaviour as per config, then at least state
whether we're forcing it off or on.

Touchscreens are devices that do not have buttons and only advertise
BTN_TOUCH. Add a new flag to note the device type.
If BTN_TOUCH is detected, change it to BTN_LEFT and process it normally.

We now have the matching code in the server to set the console to RAW mode and
don't need to grab the devices anymore.
This is an updated version of e8534d47c8524ac081c2e3e6ebaabe4c6b274a18, which
was reverted in 6dc41991557fa55a9e2f5aaf0fe40c70a08d41fd.

If we only have keys > 255 we don't set up a key class rec, so don't post
them. It makes the server unhappy.

This includes shuffling some functions around so we don't need the prototypes
in evdev.h.

Call the PreInit functions for MB Emulation, wheel emu, and draglock during
PreInit, not on DEVICE_INIT. This way, we only parse the options once and
don't overwrite with defaults when coming back from a VT switch.

Path was just an alias for Device anyway, so we might as well not parse it.
By now you should be using HAL anyway which fills in Device for you.

If checkonly is TRUE, we can only check if applying the value would succeed.
The value is actually applied if checkonly is FALSE.

This allows the reopen logic to kick in later.
DEVICE_CLOSE gets called on regen, so without this we'd keep a stale
file descriptor in pInfo->fd in subsequent sessions.
