[PATCH] input: evdev: Use multi-reader buffer to save space (rev5)

[PATCH] Input: evdev - use monotonic clock for event timestamps
Using wallclock time for event timestamps subjects inter-event timing to ntp and other clock adjustments. This complicates userspace drivers that use these timestamps to calculate velocities, or while processing state transitions. Instead, use the ...

[PATCH v2] Input: evdev - Add EVIOC mechanism to extract the MT slot state
This patch adds the ability to extract the MT slot state sequentially via EVIOCGABS. The slot parameter is first selected by calling EVIOCSABS with ABS_MT_SLOT as argument, followed by a set of EVIOCGABS calls. The slot selection is local to the ...

[PATCH] Input: Add ioctl to block suspend while event queue is not empty.
Add an ioctl, EVIOCSSUSPENDBLOCK, to block suspend while the event queue is not empty. This allows userspace code to process input events while the device appears to be asleep. Signed-off-by: Arve Hjønnevåg <arve@android.com> ...

[PATCH 0/4] input: evdev: Dynamic buffers (rev3)
Dmitry, Please find enclosed the third version of the evdev buffer patches. This version has one more patch; the locking mechanism has been broken out into its own file, buflock.h, adding a fair amount of documentation. The mechanism has been ...

[PATCH 0/4] input: evdev: Dynamic buffers (rev5)
Hi Dmitry, Please find enclosed the fifth version of the evdev buffer patches. In this version, the buffer scheme is left intact, leaving a single patch to make the client buffers dynamic. Mostly harmless. The rest of the patches are rebased ...

[RFC][PATCH] input: Introduce device information ioctl
Today, userspace sets up an input device based on the data it emits. This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need ...

[PATCH 0/3] input: evdev: Dynamic buffers (rev4)
Dmitry, Please find enclosed the fourth version of the evdev buffer patches. This version implements buffer locking using event_lock as you suggested, such that we can proceed with fixing the evdev buffer problem independently from providing a ...

[PATCH] input: remove useless synchronize_rcu() calls
There is no need to call synchronize_rcu() after a list insertion, or a NULL->ptr assignment. However, the reverse operations do need this call. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Paul E. McKenney ...
