GPU fwget wrinkle

I just read an email from BSD Weekly that seems to have shed some light on a recent issue I've seen a number of times.  Recall that I've mentioned something about amdgpu_picasso_gpu_info_bin.ko, the issue being mention of firmware that was missing.  The error message was too involved to copy down but I did catch the info filename that was repeated in the message.  I didn't know there was anything I could do about it.

Introducing FreeBSD’s fwget(8) for Firmware Management: The article discusses the fwget(8) tool in FreeBSD, introduced to manage firmware for hardware components like WiFi and GPU.  The author encountered WiFi issues after upgrading to FreeBSD 14.3-RELEASE, discovering that the Intel Wi-Fi 6 AX201 required firmware not included by default.  Running fwget(8) automatically detected and installed the missing iwlwifi-QuZ-a0-hr-b0-77.ucode firmware, restoring WiFi functionality.  The tool scans hardware devices, identifies missing firmware, and installs necessary packages (e.g., wifi-firmware-iwlwifi-kmod-22000).  The author notes the lack of official documentation in the FreeBSD Handbook, though a bug report (#286402) addresses this gap.

Obviously this intrigued me, so I tested to see more about it.

FWGET(8)                FreeBSD System Manager's Manual               FWGET(8)

NAME
     fwget – install firmware packages for the running system

SYNOPSIS
     fwget [-n] [-v] [subsystem]

DESCRIPTION
     The fwget utility can be used to detect and install firmware packages for
     devices present on a running system.

     The options are as follows:

     -n          Dry run, only show needed packages

     -v          Be more verbose

     subsystem   Hardware subsystem(s), default is all supported subsystems.
                 Space separated hardware subsystems, accepts pci and usb

SEE ALSO
     firmware(9)

HISTORY
     The fwget utility first appeared in FreeBSD 14.0.

AUTHORS
     The fwget utility and this manual page were written by Emmanuel Vadot
      for Beckhoff Automation GmbH & Co.  KG.

CAVEATS
     This utility currently only supports the pci(4) and usb(4) subsystems.

FreeBSD 15.0-ALPHA5              July 7, 2025                         FWGET(8)

It seems that all I need to do now, is actually use fwget (not a dry run) and test with a reboot.  I wonder what will be different, everything seems to be working fine without this but maybe I'm not using picasso at all?

I seem to be rather horrible at this, I should have checked what was at /boot/firmware before I ran the command.  I knew this directory existed but didn't know there was a way to populate it.  I'm not going to erase the directory and use fwget to repopulate it, but I probably could.  Erasing it and using fwget would just restore it to what I have now, so I still wouldn't know which file was added for the picasso.  What is interesting though is that all but one file ends with fw, which makes me wonder why one ends with C instead.

I guess the next thing to do is reboot and see what happens.  Will my amdgpu work, work better, or will I have more work myself to fix things yet again?

How rarely things are easy.  When I rebooted somehow graphics was broken again.  This likely was a hidden change that was discovered only due to things in memory being unloaded.  I don't know for certain what caused it.  Among various things I did while graphics was failing for me, was to erase the contents of /boot/firmware and just to be sure everything else was in place, I went to /usr/src to make buildworld and make installworld.  What I discovered was that that was what populated /boot/firmware, so that puzzle is solved.

However, after a lot of round and round effort, I now know that sometimes the firmware I hope to install is ignored.  If I use graphics/gpu-firmware-kmod, I believe it installs everything under the sun, all the flavors it turns out to be.  If I use graphics/gpu-firmware-amd-kmod by itself, it will install the very first firmware flavor only, aldebaran.  With a few trials and errors, I figured out that if I make FLAVOR=picasso install FLAVOR=picasso clean, then it does everything I need for it to do.

What becomes interesting in a very head-scratching way, is if fwget tells me in Dry run "Needed firmware packages: 'gpu-firmware-amd-kmod-picasso'" then why does it not actually install gpu-firmware-amd-kmod-picasso or what was I missing that caused another panic at boot?

I can verify that it does install it (just as Vermaden had in his post), in an odd location, and I note the date difference as well, which means it was most recent.

What seems likely is that the gpu-firmware-amdgpu-kmod files for picasso were somehow missing.  Each time I am forced to spend time solving these software riddles, it usually ends up teaching me something that I hopefully remember for next time.  If all else fails, I do have these blog posts as reference in the future.  As an overview though, for my graphics to function, I need the gpu-firmware-amdgpu-kmod picasso files, drm-kmod, and in /etc/rc.conf.local set kld_list="amdgpu" and all should be fine.  Something that is interesting, is that when I was solving problems in singleuser, I couldn't use fwget even though I was root, it claimed insufficient priviledges.

One thing fwget does is identify and install the right firmware for my amdgpu.  If I use graphics/drm-kmod to install that, it also installs all flavors of gpu-firmware-kmod, amdgpu, radeon, and intel.  In order to remove the excesses and only keep the picasso stuff, I can go to each of graphics/gpu-firmware-amdgpu-kmod, graphics/gpu-firmware-intel-kmod, and graphics/gpu-firmware-radeon-kmod and issue make FLAVOR=* deinstall and then go back to graphics/gpu-firmware-amdgpu-kmod to install FLAVOR=picasso, or more simply, just use fwget.  It may be easier to periodically comment out the RUN_DEPENDS line in graphics/drm-kmod which may have the side-effect of future updates not pulling all of the extras back again.  If something doesn't work by using fwget for whatever reason, it still indicates the correct driver so that it can be installed another way.
