I have a Microsoft Surface Go 4 Tablet, which has an internal 256 GB UFS-Drive.
Debian Live works fine, but its not possible to install Debian: When I get to
partitioning, the installer does not see the drive (the ubuntu installer does)
and only shows my installer-stick.

I guess the installer would need the ufshci-module to recognize the internal
UFS-Flash.

Tried with the stable-installer from Debian 12 and also with the daily build
from testing, no difference.

So this bug report concerns only the official debian 12 netinstall.

Hi Patrick,

and thanks for your report.

Patrick Rudin <taxi_bs@gmx.ch> (2023-10-14):

Looking around, it seems “ufshci-module” is a best guess name for what
the industry calls UFSHCI, and seems to be shipped as ufshcd-core.ko
(ufs/core) and ufshcd-pci.ko (ufs/host). Those are likely to be
sufficient as the only dependency is between them (no extra modules
should be needed), and I can load both of them in a test VM. But we've
already seen that sometimes another seemingly unrelated module might be
needed (I did spot a softdep on a governor, so I'm not sure about the
runtime when such a device is present).

I've built a test netboot-gtk installation image; contrary to a full
netinst ISO, there's no firmware in there, but I thought it might be
good enough for you to test and report whether the storage appears,
without going through the whole installation process.

Your follow-up about Live was very nice as well. Hopefully that fits
your immediate needs and lets you install Debian without waiting on a
fix in debian-installer; a full netinst ISO could be arranged
otherwise.


Cheers,

Hi Cyril :)

YES! Thank you, works perfectly. I can see the drive and all partitions.

Of course an alpha installer for trixie with ufs would be nice, as most people with a surface go 4 probably want Gnome 45...


By the way, this is the lspci -vv entry of the drive:

Thanks for all your work!

Sorry for the html-posts.

However, official trixie-installer still does not support the ufs-drive.

Patrick

I worked with the calamares-installer so far, but the system is really buggy and the localization is completely broken. So I would be extremly glad if you could provide a full netinstall-image for trixie or forky...
