Page to keep track of Linux support development for Thinkpad X13s (SoC codename sc8280xp), the first Thinkpad with an Arm CPU.
Most of the following information comes from #aarch64-laptops on OFTC, #fedora-arm on Libera.chat and arm[AT]lists.fedoraproject.org. Upstream information changes daily, so this page may be outdated.
Bootable images
Fedora 40 GA works relatively well OOTB. The Workstation raw image can be used with the following additions:
- The kernel must be booted with
arm64.nopauth clk_ignore_unused pd_ignore_unused rd.driver.blacklist=msm - A recent firmware must be on the machine, and the linux/DT mode must be selected in the FW menus.
- Recommend minimum version:
- Version: N3HET84W (1.56 )
- Recommend minimum version:
- A 6.5 or newer device tree must be placed on the ESP of the internal NVMe disk and named sc8280xp-lenovo-thinkpad-x13s.dtb
- ex: /boot/efi/sc8280xp-lenovo-thinkpad-x13s.dtb
- As a workaround, add a devicetree line in grub to load the DTB until it can be put in place on the ESP
- Debian has instructions on how to do this from windows
- To boot from USB,
modprobe.blacklist=qcom_q6v5_pasmust be added to the boot arguments. This keeps the USB from being reset and the storage device from being renamed mid-boot.
- Once the system is running, installing the x13s copr, will pull in the remaining dependencies and correct a few configuration items:
dnf copr enable jlinton/x13s; dnf install x13s
- Reboot
- After major kernel updates, it is probably wise for the time being to run
cp /boot/dtb-`uname -r`/qcom/sc8280xp-lenovo-thinkpad-x13s.dtb /boot/efi
Known Problems
- Audio works but is quiet
- TPM support is missing
- 5G Modem
- Need to follow the documented steps to unlock the modem
- Virtualization is not available. The UEFI is not yet exposing the EL2 (exception level), which is required to run VMs
- There has been some work done to unlock it with https://github.com/TravMurav/slbounce. YMMV
- The system does not suspend correctly so you need to poweroff if leaving unused
- Camera is not working. There are patches going upstream. You need to add cma=128M
- Bluetooth doesn't always work
