2015-01-08Input: i8042 - reset keyboard to fix Elantech touchpad detectionSrihari Vijayaraghavan1-0/+32
On some laptops, keyboard needs to be reset in order to successfully detect touchpad (e.g., some Gigabyte laptop models with Elantech touchpads). Without resettin keyboard touchpad pretends to be completely dead. Based on the original patch by Mateusz Jończyk this version has been expanded to include DMI based detection & application of the fix automatically on the affected models of laptops. This has been confirmed to fix problem by three users already on three different models of laptops.

2014-10-31Revert "Input: i8042 - disable active multiplexing by default"Dmitry Torokhov1-8/+273
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.

2014-10-11Input: i8042 - disable active multiplexing by defaultDmitry Torokhov1-273/+8
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.

It seems that many laptops do not fully implement AUX LOOP command in their keyboard controllers, causing issues with touchpad detection. We know however that almost every laptop/portable uses a PS/2 pointing device and, even if user disables it in favor of an external mouse, the system will not use IRQ 12 for anything else. Therefore we may bypass AUX IRQ delivery test when running on a laptop and assume that it is routed properly. Just to be safe we require the box to have good PNP data in order to bypass the test.
