Input: i8042 - disable active multiplexing by default

2014-10-11T18:34:43+00:00

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.

Input: i8042 - add noloop quirk for Asus X750LN

2014-10-11T18:34:42+00:00

Without this the aux port does not get detected, and consequently the
touchpad will not work.

Fix the format string for serio device name generation to avoid negative
device numbers when the id exceeds the maximum signed integer value.

Input: i8042 - fix Asus X450LCP touchpad detection

2014-09-24T23:26:56+00:00

We need to add this module to the nomux table to be able to detect the
touchpad.

Input: i8042 - also set the firmware id for MUXed ports

2014-09-12T06:32:52+00:00

So that firmware-id matching can be used with multiplexed aux ports too.

Input: i8042 - add nomux quirk for Avatar AVIU-145A6

2014-09-12T06:32:07+00:00

The sys_vendor / product_name are somewhat generic unfortunately, so this
may lead to some false positives. But nomux usually does no harm, where as
not having it clearly is causing problems on the Avatar AVIU-145A6.

Input: serport - add compat handling for SPIOCSTYPE ioctl

2014-09-10T17:27:42+00:00

When running a 32-bit inputattach utility in a 64-bit system, there will be
error code "inputattach: can't set device type". This is caused by the
serport device driver not supporting compat_ioctl, so that SPIOCSTYPE ioctl
fails.

Input: sparc - i8042-sparcio.h: fix unused kbd_res warning

2014-08-19T21:20:40+00:00

kbd_res is used only when CONFIG_PCI is defined; condition its declaration as
well. This fixes the following compilation warning:

  drivers/input/serio/i8042-sparcio.h:20:25: warning: ‘kbd_res’ defined but not used [-Wunused-variable]
