The userspace application/driver would then say: Oh, I don't have enough memory for triple buffering, maybe I should just fallback to double buffering....
Retrying the same approach over and over again is not really a good implementation from userspace.
But devices with only 64MiB of VRAM are rare today, so....

Hi Chrisitan,
you are right, after bumping the memory in BIOS the error goes away. Still would be nice if the error would point to "out of VMem" or something.

Hi,
I have installed Debian 12 on my old Fujitsu S920 with AMD GX-424CC.
After the installation completed, my logs are flooded by the following error messages:

I'm a bit confused. Is this an kernel issue, Xorg issue or something else?
Well, what is connected to the GPU? E.g. what monitor, projector or other display device do you use?
What happens is that only 64MiB is assigned to the device and for some reason a process (maybe the compositor?) Is trying to do double or triple buffering and doesn't has enough memory for that.
So it falls back to single buffering, that might work but will probably not look as good and you see tons of error messages.
You most likely can go into the BIOS and reserve more memory to the GPU (it will just be stolen from system memory).
Regards,
Christian.

I searched bug tracker and could only find this issue: https://gitlab.freedesktop.org/xorg/driver/xf86-video-ati/-/issues/180 but I don't have a black screen. The system is rather sluggish but seems to work.I did try older version of Debian back to 10.13. All have this issue. I'm very sure the eLux which came with the box did not have this.
Any hints where to go next is very appreciated.Best Regards
