Subject: [PATCH v3 0/3] X1E Dell XPS 9345 support
Date: Fri, 27 Sep 2024 11:44:17 +0200 [thread overview]
Message-ID: <20240927094544.6966-1-alex.vinarskis@gmail.com> (raw)
Introduce support for the mentioned laptop.
Very similar to other X1E laptops, device tree was derived by analyzing dtsi of
existing models and ACPI tables of this laptop [1]. Most notable difference were
* TZ protected SPI19.
* Keyboard only working after suspend/resume sequence, will do a follow up patch
to i2c-hid.
* Lots of small deviations in LDOs voltages.
Successfully tested with Debian 12 and Gnome, although this required additional
patches, namely harcode GPU chipid, apply [2] and _revert_ [3] - same as in Abel
Vesa's branches. Without last two the boot process is terminated by TZ. Firmware
for GPU/aDSP/cDSP was extracted from Windows, WiFi firmware from upstream
linux-firmware.
Quite a few things alraedy work, details in patches, quite a few still in WIP or
TODOs. Since fixing these may take me a while due to lack of documentation,
sending current progress as its very much usable.
