Input: i8042 - add Pegatron touchpad to noloop table

2017-01-19T19:17:57Z

commit 41c567a5d7d1a986763e58c3394782813c3bcb03 upstream. Avoid AUX loopback in Pegatron C15B touchpad, so input subsystem is able to recognize a Synaptics touchpad in the AUX port.

Input: i8042 - add XMG C504 to keyboard reset table

2016-10-19T19:10:04Z

The Schenker XMG C504 is a rebranded Gigabyte P35 v2 laptop. Therefore it also needs a keyboard reset to detect the Elantech touchpad. Otherwise the touchpad appears to be dead. With this patch the touchpad is detected: $ dmesg | grep -E "(i8042|Elantech|elantech)" [ 2.675399] i8042: PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12 [ 2.680372] i8042: Attempting to reset device connected to KBD port [ 2.789037] serio: i8042 KBD port at 0x60,0x64 irq 1 [ 2.791586] serio: i8042 AUX port at 0x60,0x64 irq 12 [ 2.813840] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input4 [ 3.811431] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x361f0e) [ 3.825424] psmouse serio1: elantech: Synaptics capabilities query result 0x00, 0x15, 0x0f.

Input: i8042 - skip selftest on ASUS laptops

2016-10-11T23:58:25Z

On suspend/resume cycle, selftest is executed to reset i8042 controller. 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. All models affected by this problem: A455LD K401LB K501LB K501LX R409L V502LX X302LA X450LCP X450LD X455LAB X455LDB X455LF Z450LA [1]: https://marc.info/?l=linux-input&m=144312209020616&w=2 Fixes: "ETPS/2 Elantech Touchpad dies after resume from suspend" (https://bugzilla.kernel.org/show_bug.cgi?id=107971) Signed-off-by: Marcos Paulo de Souza Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

Input: serio - add hangup support

2016-09-21T14:57:11Z

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 Tested-by: Hans Verkuil Signed-off-by: Dmitry Torokhov

Input: i8042 - set up shared ps2_cmd_mutex for AUX ports

2016-08-19T17:08:49Z

The commit 4097461897df ("Input: i8042 - break load dependency ...") correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do the same for AUX port(s), which results in communication on KBD and AUX ports to clash with each other.

Input: i8042 - break load dependency between atkbd/psmouse and i8042

2016-07-27T21:20:09Z

As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we have a hard load dependency between i8042 and atkbd which prevents keyboard from working on Gen2 Hyper-V VMs. > hyperv_keyboard invokes serio_interrupt(), which needs a valid serio > driver like atkbd.c. atkbd.c depends on libps2.c because it invokes > ps2_command(). libps2.c depends on i8042.c because it invokes > i8042_check_port_owner(). As a result, hyperv_keyboard actually > depends on i8042.c. > > For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a > Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m > rather than =y, atkbd.ko can't load because i8042.ko can't load(due to > no i8042 device emulated) and finally hyperv_keyboard can't work and > the user can't input: https://bugs.archlinux.org/task/39820 > (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y) To break the dependency we move away from using i8042_check_port_owner() and instead allow serio port owner specify a mutex that clients should use to serialize PS/2 command stream.
