Once the system is installed you need to install pd-mapper and enable the pd-mapper service to get battery charge reporting working
*Once the system is running, installing the [https://copr.fedorainfracloud.org/coprs/jlinton/x13s/ x13s copr], will pull in the remaining dependencies and correct a few configuration items:
* `sudo dnf install -y pd-mapper; sudo systemctl enable --now pd-mapper.service`
** <pre>dnf copr enable jlinton/x13s; dnf install x13s</pre>
** Charging may not work at all though any number of USB-C hubs
*** Reboot
Anaconda persists module.blacklist boot arguments to the installed system in order for pd-mapper to run properly we need to remove `/etc/modprobe.d/anaconda-denylist.conf` and regenerate the initrd with `sudo dracut -f` to enable qcom_q6v5_pas to be loaded automatically.

==== Bluetooth ====
** While waiting on a new release of ModemManager we can take the following steps
By default there is no Bluetooth mac address set. You can manually set an address with btmgmt. e.g., `sudo btmgmt public-addr 00:A0:C6:30:A3:47`
 
To make it just work, copy this file to `/etc/systemd/system/bluetooth.service.d/override.conf` (It is courteous to use your own public-addr, put a random string of numbers to make it unique. Starting with a Qualcomm related OUI, ex: 00:A0:C6, followed by 3 random IDs.)
 
<pre>
[Service]
ExecStartPre=/bin/bash -c 'sleep 5 && yes | btmgmt public-addr 00:A0:C6:17:62:36'
# Blank ExecStart line to clear the service file, overrides are additive.
ExecStart=
ExecStart=/usr/libexec/bluetooth/bluetoothd
</pre>
 
==== Touch Screen ====
There is some probe defer issue to get touch screen bound to i2c_hid_of driver. To workaround temporarily run `sudo echo 4-0010 > /sys/bus/i2c/drivers/i2c_hid_of/bind` to make it persit install the file at https://github.com/ironrobin/x13s-alarm/blob/trunk/x13s-touchscreen-udev/72-x13s-touchscreen.rules in `/etc/udev/rules.d/`
==== 5G Modem ====
While waiting on a new release of ModemManager we can take the following steps
<pre>

sudo ln -s 105b /usr/share/ModemManager/fcc-unlock.available.d/105b\:e0c3

Revision as of 19:46, 20 December 2023

Page to keep track of Linux support development for Thinkpad X13s (SoC codename sc8280xp), the first Thinkpad with ARM CPU.

Most of following informations come from #aarch64-laptops on OFTC, #fedora-arm on Libera.chat and arm[AT]lists.fedoraproject.org. Upstream infos change on daily basis, so this page may be outdated, therefore read it with pinch of salt / cum grano salis.

Bootable images

Fedora Rawhide images are bootable as of the 15th of December, 2023. There are, unfortunately some boot arguments that need to be added to boot successfully

  • 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 )
  • 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
  • to boot from USB you need to add modprobe.blacklist=qcom_q6v5_pas to the boot arguments, this keeps the USB from being reset and the storage device 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
    • While waiting on a new release of ModemManager we can take the following steps
sudo ln -s 105b /usr/share/ModemManager/fcc-unlock.available.d/105b\:e0c3
sudo mkdir -p /etc/ModemManager/fcc-unlock.d
sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
