Hans de Goede	0fca22a5b0	Input: atkbd - use ab83 as id when skipping the getid command ... commit 58f65f9db7e0de366a5a115c2e2c0703858bba69 upstream. Barnabás reported that the change to skip the getid command when the controller is in translated mode on laptops caused the Version field of his "AT Translated Set 2 keyboard" input device to change from ab83 to abba, breaking a custom hwdb entry for this keyboard. Use the standard ab83 id for keyboards when getid is skipped (rather then that getid fails) to avoid reporting a different Version to userspace then before skipping the getid.

Hans de Goede	7cd9c291da	Input: atkbd - skip ATKBD_CMD_GETID in translated mode ... [ Upstream commit 936e4d49ecbc8c404790504386e1422b599dec39 ] There have been multiple reports of keyboard issues on recent laptop models which can be worked around by setting i8042.dumbkbd, with the downside being this breaks the capslock LED. It seems that these issues are caused by recent laptops getting confused by ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode. The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2 mice/touchpads and those are never used in translated mode. Examples of laptop models which benefit from skipping ATKBD_CMD_GETID: * "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx" models the kbd stops working for the first 2 - 5 minutes after boot (waiting for EC watchdog reset?) * On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard * At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see: https://github.com/yescallop/atkbd-nogetid This has been tested on: 1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not in translated mode when no keyboard is plugged in and with a ps/2 kbd a "AT Translated Set 2 keyboard" /dev/input/event# node shows up 2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard) Reported-by: Shang Ye <yesh25@mail2.sysu.edu.cn> Closes: https://lore.kernel.org/linux-input/886D6167733841AE+20231017135318.11142-1-yesh25@mail2.sysu.edu.cn/ Closes: https://github.com/yescallop/atkbd-nogetid Reported-by: gurevitch <mail@gurevit.ch> Closes: https://lore.kernel.org/linux-input/2iAJTwqZV6lQs26cTb38RNYqxvsink6SRmrZ5h0cBUSuf9NT0tZTsf9fEAbbto2maavHJEOP8GA1evlKa6xjKOsaskDhtJWxjcnrgPigzVo=@gurevit.ch/ Reported-by: Egor Ignatov <egori@altlinux.org> Closes: https://lore.kernel.org/all/20210609073333.8425-1-egori@altlinux.org/ Reported-by: Anton Zhilyaev <anton@cpp.in> Closes: https://lore.kernel.org/linux-input/20210201160336.16008-1-anton@cpp.in/ Closes: https://bugzilla.redhat.com/show_bug.cgi?id=2086156 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20231115174625.7462-1-hdegoede@redhat.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Sasha Levin <sashal@kernel.org>	2024-11-18 12:12:16 +01:00
