Now serio_find_driver() will print warnings in case device_attach() returns -EPROBE_DEFER. Those warnings are obsolete, in genral, because: - DD core can report the same if required - since commit 013c074f8642 ("PM / sleep: prohibit devices probing during suspend/hibernation") the devices probing is prohibited during System suspend and deferred device will be carefully reprobed once Resume is finished. Hence, drop warnings in case of EPROBE_DEFER from serio_find_driver(). Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Rafael J.

2015-10-27Input: add userio moduleStephen Chandler Paul3-0/+300
Debugging input devices, specifically laptop touchpads, can be tricky without having the physical device handy. Here we try to remedy that with userio. This module allows an application to connect to a character device provided by the kernel, and emulate any serio device. In combination with userspace programs that can record PS/2 devices and replay them through the /dev/userio device, this allows developers to debug driver issues on the PS/2 level with devices simply by requesting a recording from the user experiencing the issue without having to have the physical hardware in front of them.

2015-10-14input: i8042: Avoid resetting controller on system suspend/resumeRafael J. Wysocki1-5/+27
If the upcoming system suspend is not going to be handled by the platform firmware, like in the suspend-to-idle case, it is not necessary to reset the controller in i8042_pm_suspend(), so avoid doing that. Moreover, if the system resume currently in progress has not been started by the platform firmware, like in the suspend-to-idle case, i8042_controller_resume() need not be called by i8042_pm_resume(), so avoid doing that too in that case. Additionally, try to catch the event that woke up the system by calling the interrupt handler early during system resume if it has not been started by the platform firmware. Signed-off-by: Rafael J.

2015-09-29Input: psmouse - fix data race in __ps2_commandDmitry Vyukov1-8/+14
The data race happens on ps2dev->cmdcnt and ps2dev->cmdbuf contents. __ps2_command reads that data concurrently with the interrupt handler. As the result, for example, if a response arrives just after the timeout, __ps2_command can copy out garbage from ps2dev->cmdbuf but then see that ps2dev->cmdcnt is 0 and return success. Stop the interrupt handler with serio_pause_rx() before reading the results. The data race was found with KernelThreadSanitizer (KTSAN).

A big problem with the current i8042 debugging option is that it outputs data going to and from the keyboard by default. As a result, many dmesg logs uploaded by users will unintentionally contain sensitive information such as their password, as such it's probably a good idea not to output data coming from the keyboard unless specifically enabled by the user.

2014-10-31Revert "Input: i8042 - disable active multiplexing by default"Dmitry Torokhov2-9/+274
This reverts commit 68da166491655bc54051bf04c78ce648e2e33508. It turns out that the assertion about scope of regressions due to always keeping keyboard controller in legacy mode was proven wrong. There are laptops, such as Clevo W650SH, that only have internal touchpad (no external PS/2 ports), that require active multiplexing mode to switch the touchpad (Elantech) into native mode instead of basic PS/2 emulation.

The irq function altera_ps2_rxint returns an irqreturn_t, so use the same type for variable storing the return value. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-10-31Input: altera_ps2 - write to correct register when disabling interruptsTobias Klauser1-1/+1
In altera_ps2_close, the data register (offset 0) is written instead of the control register (offset 4), leading to the RX interrupt not being disabled. Fix this by calling writel() with the offset for the proper register. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2014-10-11Input: i8042 - disable active multiplexing by defaultDmitry Torokhov2-274/+9
Active multiplexing is a nice feature as it allows several pointing devices (such as touchpad and external mouse) use their native protocols at the same time. Unfortunately many manufacturers do not implement the feature properly even though they advertise it. The problematic implementations are never fixed, since Windows by default does not use this mode, and move from one BIOS/model of laptop to another. When active multiplexing is broken turning it on usually results in touchpad, keyboard, or both unresponsive. With PS/2 usage on decline (most of PS/2 devices in use nowadays are internal laptop touchpads), I expect number of users who have laptops with working MUX implementation, docking stations with external PS/2 ports, and who are still using external PS/2 mice, to be rather small. Let's flip the default to be OFF and allow activating it through i8042.nomux=0 kernel option. We'll also keep DMI table where we can record known good models.
