Dmitry, Jiri, Here is the tentative patchset planned for 3.7. It touches both the Input and HID subsystems, so I decided to send it to both of you at once. How to distribute the patches can be decided later. The gist of the set is in-kernel tracking and latency. As I started measuring irqsoff times, I realized we did quite poorly in that department. Consequently, some of the patches are general and substantial speedups which ought to make everybody happy. Patches 1-6 rearranges the input core to send packets of events instead of one event at a time. Patch 7 implements this in evdev. Patches 8-11 incorporate more duplicated code into mt core, and implements a simple - but correct - form of tracking. Earlier variants have either been complex, approximate or slow. This one is only about 50 lines of code and fast enough to handle ten fingers in interrupt context. Patches 12-15 convert bcm5974 to MT-B. Patch 16 is janitory. Patch 17 provides a substantial latency improvement on simple key strokes. Patches 18-19 are for hid-multitouch, reducing memory and simplifying the driver. Thanks, Henrik Henrik Rydberg (19): Input: Break out MT data Input: Improve the events-per-packet estimate Input: Remove redundant packet estimates Input: Make sure we follow all EV_KEY events Input: Move autorepeat to the event-passing phase Input: Send events one packet at a time Input: evdev - Add the events() callback Input: MT - Add flags to input_mt_init_slots() Input: MT - Handle frame synchronization in core Input: MT - Add in-kernel tracking Input: MT - Add slot assignment by id Input: bcm5974 - Preparatory renames Input: bcm5974 - Drop pressure and width emulation Input: bcm5974 - Drop the logical dimensions Input: bcm5974 - Convert to MT-B HID: hid-multitouch: Remove misleading null test HID: Only dump input if someone is listening HID: Add an input configured notification callback HID: multitouch: Remove the redundant touch state drivers/hid/hid-core.c | 3 +- drivers/hid/hid-input.c | 15 +- drivers/hid/hid-magicmouse.c | 4 +- drivers/hid/hid-multitouch.c | 172 ++++++++---------- drivers/input/evdev.c | 78 +++++--- drivers/input/input-mt.c | 297 ++++++++++++++++++++++++++++--- drivers/input/input.c | 252 +++++++++++++++----------- drivers/input/misc/uinput.c | 2 +- drivers/input/mouse/alps.c | 2 +- drivers/input/mouse/bcm5974.c | 274 ++++++++++------------------ drivers/input/mouse/elantech.c | 4 +- drivers/input/mouse/sentelic.c | 2 +- drivers/input/mouse/synaptics.c | 4 +- drivers/input/tablet/wacom_wac.c | 6 +- drivers/input/touchscreen/atmel_mxt_ts.c | 2 +- drivers/input/touchscreen/cyttsp_core.c | 2 +- drivers/input/touchscreen/edt-ft5x06.c | 2 +- drivers/input/touchscreen/egalax_ts.c | 2 +- drivers/input/touchscreen/ili210x.c | 2 +- drivers/input/touchscreen/mms114.c | 2 +- drivers/input/touchscreen/penmount.c | 2 +- drivers/input/touchscreen/wacom_w8001.c | 2 +- include/linux/hid.h | 3 + include/linux/input.h | 35 ++-- include/linux/input/mt.h | 53 +++++- 25 files changed, 744 insertions(+), 478 deletions(-) -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
