Reason: Needs the last PCI/USB IDs in hardware table, an accessibility section and a proper function keys table to be added. (Discuss in Talk:Panasonic CF-SV9)

Firmware

System firmware, UEFI firmware, firmware for Thunderbolt controller and touchpad, and SSD firmware can be updated via fwupd.

Touchpad

Circular scrolling

The device has a relatively small round-shape touchpad, so the ability to configure circular scrolling is important for usability (since the touchpad area is too small for gestures). As of 06/27/2020, libinput does not have support for circular scrolling, which means you cannot get circular scrolling in Wayland. Under Xorg, with xf86-input-synaptics installed, circular scrolling works fine with the following configuration section

/etc/X11/xorg.conf.d/70-synaptics.conf
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "0"
        Option "CircularPad" "on"
        Option "LeftEdge" "80"
        Option "RightEdge" "450"
        Option "TopEdge" "80"
        Option "BottomEdge" "450"
EndSection

After saving the file, restart Xorg.

Fix touchpad delays after system wake from sleep

Touchpad starts to behave badly and introduce pointer moving delays after system wake up from sleep. To address the issue, i2c_hid kernel module must be unloaded and loaded back again. The following script does the job:

/lib/systemd/system-sleep/fix-touchpad.sh
#!/bin/sh

if [ "$1" = 'post' ]; then
    echo "Reloading i2c_hid module to fix touchpad behavior"
    modprobe -r i2c_hid && modprobe i2c_hid
fi

Requires sof-firmware to fully function.

Function keys

Keys F1-F6 & F11-F12 work out of the box. Keys F7-F10 do not work and do not produce any key codes. According to drivers/platform/x86/panasonic-laptop.c, these buttons are supposed to perform the following functions:

{ KE_KEY, 7, { KEY_SLEEP } },
{ KE_KEY, 8, { KEY_PROG1 } }, /* Change CPU boost */
{ KE_KEY, 9, { KEY_BATTERY } },
{ KE_KEY, 10, { KEY_SUSPEND } },
