Input: i8042 - add another board name for TUXEDO Stellaris Gen5 AMD line

2024-10-04T14:29:46+00:00

commit 01eed86d50af9fab27d876fd677b86259ebe9de3 upstream. There might be devices out in the wild where the board name is GMxXGxx instead of GMxXGxX. Adding both to be on the safe side.

Input: i8042 - add TUXEDO Stellaris 15 Slim Gen6 AMD to i8042 quirk table

2024-10-04T14:29:46+00:00

commit 3870e2850b56306d1d1e435c5a1ccbccd7c59291 upstream. The Gen6 devices have the same problem and the same Solution as the Gen5 ones. Some TongFang barebones have touchpad and/or keyboard issues after suspend, fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use, no negative effects could be observed when setting all four.

[ Upstream commit 7ce7c2283fa6843ab3c2adfeb83dcc504a107858 ] Yet another quirk entry for Fujitsu laptop. Lifebook E756 requires i8041.nomux for keeping the touchpad working after suspend/resume.

Input: i8042 - use new forcenorestore quirk to replace old buggy quirk combination

2024-08-29T15:33:53+00:00

commit aaa4ca873d3da768896ffc909795359a01e853ef upstream. The old quirk combination sometimes cause a laggy keyboard after boot. With the new quirk the initial issue of an unresponsive keyboard after s3 resume is also fixed, but it doesn't have the negative side effect of the sometimes laggy keyboard.

Input: i8042 - add forcenorestore quirk to leave controller untouched even on s3

2024-08-29T15:33:53+00:00

commit 3d765ae2daccc570b3f4fbcb57eb321b12cdded2 upstream. On s3 resume the i8042 driver tries to restore the controller to a known state by reinitializing things, however this can confuse the controller with different effects. Mostly occasionally unresponsive keyboards after resume. These issues do not rise on s0ix resume as here the controller is assumed to preserved its state from before suspend. This patch adds a quirk for devices where the reinitialization on s3 resume is not needed and might be harmful as described above. It does this by using the s0ix resume code path at selected locations. This new quirk goes beyond what the preexisting reset=never quirk does, which only skips some reinitialization steps.

Input: i8042 - add Fujitsu Lifebook U728 to i8042 quirk table

2024-03-01T12:34:53+00:00

[ Upstream commit 4255447ad34c5c3785fcdcf76cfa0271d6e5ed39 ] Another Fujitsu-related patch. In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all.

Input: i8042 - fix strange behavior of touchpad on Clevo NS70PU

2024-02-16T18:10:55+00:00

commit a60e6c3918d20848906ffcdfcf72ca6a8cfbcf2e upstream. When closing the laptop lid with an external screen connected, the mouse pointer has a constant movement to the lower right corner. Opening the lid again stops this movement, but after that the touchpad does no longer register clicks. The touchpad is connected both via i2c-hid and PS/2, the predecessor of this device (NS70MU) has the same layout in this regard and also strange behaviour caused by the psmouse and the i2c-hid driver fighting over touchpad control. This fix is reusing the same workaround by just disabling the PS/2 aux port, that is only used by the touchpad, to give the i2c-hid driver the lone control over the touchpad. v2: Rebased on current master Signed-off-by: Werner Sembach Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20231205163602.16106-1-wse@tuxedocomputers.com Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: i8042 - add nomux quirk for Acer P459-G2-M

[ Upstream commit 335fe00319e030d481a54d5e0e68d50c5e672c0e ] After the laptop lid is opened, and the device resumes from S3 deep sleep, if the user presses a keyboard key while the screen is still black, the mouse and keyboard become unusable. Enabling this quirk prevents this behavior from occurring.
