Debian bookworm on a Lenovo T14s Gen3 AMD

[Marco d'Itri]

I recently upgraded my laptop to a Lenovo T14s Gen3 AMD and I am happy
to report that it works just fine with Debian/unstable using a 5.19
kernel.

The only issue is that some firmware files are still missing and I had
to install them manually.

Updates are needed for the firmware-amd-graphics package (#1019847[0])
for the Radeon 680M GPU (AMD Rembrandt) and for the firmware-atheros
package (#1021157[1]) for the Qualcomm NFA725A Wi-Fi card (which is
actually reported as a NFA765).

s2idle (AKA "modern suspend") works too.

For improved energy efficiency it is recommended to switch from the
acpi_cpufreq CPU frequency scaling driver to amd_pstate[2]. Please note
that so far it is not loaded automatically.

As expected, fwupdmgr can update the system BIOS and the firmware of
the NVMe device.
