2011-04-28Input: sh_keysc - switch to threaded IRQ handlerMagnus Damm1-1/+2
Update the KEYSC driver to make use of threaded IRQs with IRQF_ONESHOT to improve interrupt latency. The driver is using udelay() in the ISR to make sure the hardware has stabilized. Without using interrupt threads this delay may affect the latency of the rest of the system. Also pass dev_name() as string for /proc/interrupts.

2011-04-27Input: wm831x-ts - move BTN_TOUCH reporting to data transferMark Brown1-3/+2
Don't report BTN_TOUCH until we've got data as some less robust applications can be confused by getting a touch event by itself and it doesn't seem unreasonable for them to expect coordinates along with a touch.

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.

2011-04-18Input: xen-kbdfront - fix mouse getting stuck after save/restoreIgor Mammedov1-1/+12
Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates"). Driver on restore should ask xen for request-abs-pointer again if it is available. So restore parts that did it before 5ea5254.

On a "really fragile" laptop I noticed a single i8042.c: i8042 controller selftest failed. (0x1 != 0x55) error in the log. But there's no reason to print this message at KERN_ERR level each time that loop fails, especially since the message telling about the overall selftest failure is printed at KERN_INFO level (on X86). Add an actual error message for non-X86 systems, where a selftest failure is (apparently) more serious. Remove a space in an another error message.

'struct dmi_system_id' arrays must always have a terminator to keep dmi_check_system() from looking at data (and possibly crashing) it isn't supposed to look at. The issue went unnoticed until ef8313bb1a22e7d2125d9d758aa8a81f1de91d81, but was introduced about a year earlier with 7705d548cbe33f18ea7713b9a07aa11047aaeca4 (which also similarly changed lifebook.c, but the problem there got eliminated shortly afterwards). The first hunk therefore is a stable candidate back to 2.6.33, while the full change is needed only on 2.6.38.

Some devices provide absolute axes with min/max of 0/0 (e.g. wacom's ABS_MISC axis). Current uinput restrictions do not allow duplication of these devices and require hacks in userspace to work around this.

Commit 0b950d3 (Input: tsc2005 - add open/close) introduced a locking issue with the ESD watchdog: __tsc2005_disable() is calling cancel_delayed_work_sync() with mutex held, and the work also needs the same mutex.
