We should only wake waiters on the event device when we actually post an EV_SYN/SYN_REPORT to the queue. Otherwise we end up making waiting threads runnable only to go right back to sleep because the device still isn't readable.

2011-05-17Input: tsc2007 - add max_rt parameter to platform dataThierry Reding2-1/+4
Finger touch events or very quick stylus events on low-quality panels can cause the tsc2007 to read bogus values. Looking at oscilloscope snapshots, this seems to be caused by the touch event disappearing during the measurements. These bogus values result in misclicks, where the X and Y values deviate from the real position. Most of these misclicks can be filtered out by setting a low enough threshold for the maximum resistance (which is loosely the inverse of the pressure) allowed to consider a set of values valid. Since this behaviour is largely dependent on the type and quality of the panel, this commit introduces the max_rt parameter. The default value is kept at MAX_12BIT.

2011-05-16Input: elantech - remove support for proprietary X driverÉric Piel1-12/+0
Apparently somewhere someone had a proprietary X driver. To get the multitouch info, it uses some hack on the normal API instead of using the multitouch protocol. Now that the multitouch info is transmitted correctly it makes not much sense to keep it. Especially because it's impossible to find this proprietary X driver anywhere, so the number of users must be very low.

2011-05-16Input: elantech - report multitouch with proper ABS_MT messagesÉric Piel1-5/+34
Multitouch info was reported only via a old protocol used by the proprietary X driver from elantech. Let's report the multitouch info also following the official MT protocol. It's semi-mt because the device only reports the lowest/highest coordinates. This was done following the multi-touch-protocol.txt documentation, and inspired by the bcm5974 and elantech implementations. Testing was light as there is not many applications using this protocol yet, but the X synaptics driver didn't complain and the X multitouch driver behaved correctly.

2011-04-27Input: wm831x-ts - fix races with IRQ managementMark Brown1-5/+49
If the WM831x pen down and data IRQs run in parallel it is possible for the data and pen down IRQs to deadlock themselves as one is part way through disabling its operation while the other is part way through enabling. Fix this by always disabling the pen down interrupt while data is active and vice versa. When a changeover is required we disable the IRQ that is to be stopped then schedule work that will enable the new IRQ. We need to handle the data flow in the data IRQ as the readback from the device needs to be ordered correctly with the IRQ for robust operation. This also fixes an issue when using the built in IRQs due to enable_irq() not being valid from interrupt context on an interrupt controller with bus operations like the built in IRQ controller - this issue may also have affected other interrupt controllers. We can't rely on having the data and pen down IRQs available via GPIOs on the CPU on every system. Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2011-04-26Input: evdev - only signal polls on full packetsJeff Brown1-6/+11
This patch modifies evdev so that it only becomes readable when the buffer contains an EV_SYN/SYN_REPORT event. On SMP systems, it is possible for an evdev client blocked on poll() to wake up and read events from the evdev ring buffer at the same rate as they are enqueued. This can result in high CPU usage, particularly for MT devices, because the client ends up reading events one at a time instead of reading complete packets. We eliminate this problem by making the device readable only when the buffer contains at least one complete packet. This causes clients to block until the entire packet is available.
