| * Input: i8042 - add TUXEDO BU1406 (N24_25BU) to the nomux listDmitry Torokhov2017-03-101-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | TUXEDO BU1406 does not implement active multiplexing mode properly, and takes around 550 ms in i8042_set_mux_mode(). Given that the device does not have external AUX port, there is no downside in disabling the MUX mode.

* | Input: serio - add fast reconnect optionDmitry Torokhov2017-03-251-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Devices connected to serio bus are quite slow, and to improve apparent speed of resume process, serio core resumes (reconnects) its devices asynchronously, by posting port reconnect requests to a workqueue. Unfortunately this means that if there is a dependent device of a given serio port (for example SMBus part of touchpad connected via both PS/2 and SMBus), we do not have a good way of ensuring resume order. This change allows drivers to define "fast reconnect" handlers that would be called in-line during system resume. Drivers need to ensure that these handlers are truly "fast".

| * | Input: i8042 - Trust firmware a bit more when probing on X86Dmitry Torokhov2016-12-191-3/+7
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error message "Can't read CTR while initializing i8042" appears on Cherry Trail-based devices at each boot time: i8042: PNP: No PS/2 controller found. Probing ports directly. i8042: Can't read CTR while initializing i8042 i8042: probe of i8042 failed with error -5 This happens because we historically do not trust firmware on X86 and, while noting that PNP does not show keyboard or mouse devices, we still charge ahead and try to probe the controller. Let's relax this a bit and if results of PNP probe agree with the results of platform initialization/quirks conclude that there is, in fact, no i8042. While at it, let's avoid using x86_platform.i8042_detect() and instead abort execution early if platform indicates that it can not possibly have i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

Similarly, disabling wakeup in the probe error path is unnecessary, as is disabling wakeup in the probe function in the first place.

| |_|_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We rely on the result of scanning PNP bus for keyboard and mouse devices to decide whether we should continue initialization of i8042 driver or not, so the probes can not be asynchronous. Also, it is not a good idea to unbind either of the PNP devices while i8042 is running, so let's disable bind/unbind for the PNP drivers through sysfs and rely on i8042 cleaning after itself properly. User can still unbind and rebind entire i8042 and that will take care of PNP drivers as well. Reviewed-by: Luis R.

But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Pulse-Eight USB CEC adapter is a usb device that shows up as a ttyACM0 device. It requires that you run inputattach in order to communicate with it via serio. This all works well, but it would be nice to have a udev rule to automatically start inputattach. That too works OK, but the problem comes when the USB device is unplugged: the tty hangup is never handled by the serio framework so the inputattach utility never exits and you have to kill it manually. By adding this hangup callback the inputattach utility now properly exits as soon as the USB device is unplugged. The udev rule I used on my Debian sid system is: SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ATTRS{idVendor}=="2548", ATTRS{idProduct}=="1002", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="pulse8-cec-inputattach@%k.service" And /etc/systemd/system/pulse8-cec-inputattach@.service is as follows: =============================================================== [Unit] Description=inputattach for pulse8-cec device on %I [Service] Type=simple ExecStart=/usr/local/bin/inputattach --pulse8-cec /dev/%I KillMode=process =============================================================== Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| * Input: add userio moduleStephen Chandler Paul2015-10-283-0/+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.

|/ | | | | | | | | | | | | | | | | | | 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.

* Input: psmouse - fix data race in __ps2_commandDmitry Vyukov2015-09-301-8/+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).
