Issue #659 has been updated by Walter Sonius.
Good to know the lacking reduced, by looking at older logs I did have the same OEM/CB firmware PS/2 dmesg situation. As in latitude 5490 OEM firmware won't list PS/2 mouse since some OEM BIOS foo moves over the PS/2 to the i2c bus during the boot. Since we lack howto impliment this with coreboot it may explaine why the trackpad works but detected as a mouse not a trackpad. Touchscreen also worked fine on the lat5490 since it was USB not i2c, does your machine came with one? Looking at your `cbmem.log` it also seems your running the whole coreboot codebase from 8 feb `coreboot-25.12-408-gf0678e3639e2-dirty Sun Feb 08`, can you pull a new clean coreboot build build environment and only copy over the `mb/dell/sklkbl_latitude` folder from your older (edited) CB:90685 build? If you know howto use `git` it should also work with a `cherry-pick` command but otherwise just copy over only that single folder onto the new code base. BTW have you applied your own `gpio.h/c` derived from running `util/inteltool -g` on the OEM firmware with secureboot disabled and booting linux using kernel parameter `iomem=relaxed` or are you running CB:90685 as is with only some edits to `devicetree.cb` and other files? You'll get a `gpio.h/c` file from the `inteltool -g > x.log` if you run it through `util/intelp2m/intelp2m -u x.log` make sure you have golang-go build tools working otherwise it won't work. You may need to do some minimal extra edits before the `gpio.h` can be used as a `gpio.c`. ---------------------------------------- Bug #659: Port of Dell Latitude 7480 https://ticket.coreboot.org/issues/659#change-2368 * Author: Gabriel Turlea * Status: New * Priority: Normal * Target version: none * Start date: 2026-07-14 ---------------------------------------- I have had success porting coreboot to the Dell Latitude 7480 based on work done by Nicholas Chin. Everything works great except the Keyboard. Once linux boots the keyboard works but has sporatic input/output lags. I am not sure what supporting documentation would help in tracking down the issue.
