Rather than letting the DDX allocate the events, allocate them once in the DIX
and just pass it around when needed.
DDX should call GetEventList() to obtain this list and then pass it into
Get{Pointer|Keyboard}Events.
We free the ValuatorClassRec quite regularly. If a SIGIO is handled while
we're swapping device classes, we can bring the server down when we try to
access lastx/lasty of the master device.
Call ProcessOtherEvents first, then for all keyboard devices let them be
wrapped by XKB. This way all XI events will go through XKB.
Note that the VCK is still not wrapped, so core events will bypass XKB.
(cherry picked from commit d627061b48)
DGAStealXXXEvent modified to take in device argument.
The evdev driver only sends one valuator when only one axis changed. We need
to check for DGA either way (xf86PostMotionEventP), otherwise we lose purely
horizontal/vertical movements.
Note that DGA does not do XI events.
When processing events from the EQ, _always_ call the processInputProc of the
matching device. For XI devices, this proc is wrapped in three layers.
Core event handling is wrapped by XI event handling, which is wrapped by XKB.
A core event now passes through XKB -> XI -> DIX.
This gets rid of a sync'd grab problem: with the previous code, core events
did disappear during a sync'd device grab on account of mieqProcessInputEvents
calling the processInputProc of the VCP/VCK instead of the actual device. This
lead to the event being processed as normal instead of being enqueued for
later replaying.
Call ProcessOtherEvents first, then for all keyboard devices let them be
wrapped by XKB. This way all XI events will go through XKB.
Note that the VCK is still not wrapped, so core events will bypass XKB.
If NoAutoAddDevices is given as a server flag, then no devices will be added
from HAL events at all. If NoAutoEnableDevices is given, then the devices will
be added (and the DevicePresenceNotify sent), but not enabled, thus leaving
policy up to the client.
Add RawDeviceEvent (pointers only for now).
This commit changes the event queue to use EventLists instead of xEvent
arrays. Only EQ is affected, event delivery still uses xEvent* (look for
comment in mieqProcessInputEvent).
RawDeviceEvents deliver driver information to the client, without clipping or
acceleration.
Calloc cursor struct to ensure devPrivates are zeroed out and don't
increase the refcnt for devices automatically when allocating a new
cursor. Use new DeviceIsPointerType() to detect if device is a pointer
_before_ device has been activated and can thus be identified and set
up grab functions accordingly. This way we can increase the refcnt
when we get a pointer grab.
dix: IsPointerDevice and IsKeyboardDevice, use same ways to identify type
of device as XI does for the XListInputDevices reply.
Autopair each non-pointer device with VCP when activating, pair with
real device after activation.
Don't return non-keyboard devices when calling GetPairedKeyboard or
PickKeyboard, otherwise we segfault for 'evdev brain'.
ambiguious request. PickPointer and PickKeyboard are used for getting
the appropriate pointer when situation is unclear.
Fix some issues with InitializeSprite.
dix, xfree86: Remove last traces of InitSprite.
