Yes, I meant 515 and I was running novsync.
glmark2 reports:

At that point, the benchmark hungup up and, after waiting a few minutes, I
killed it.
While I have little understanding of these benchmarks, the numbers look
pretty bad as does the warning at the start of the run. (That note was
repeated at the start of each test.)
Assuming drm-550-kmod is typo for drm-515-kmod.

Nope. glxinfo looks fine.
Can't believe that this graphics is MUCH worse than my 12 year old Ivy Lake

It exists and kmscube runs.

OK. I am now running libva-intel-media-driver. Still not seeing the video
acceleration that I would expect. 12 threads running and hte total CPU
usage is 9& to play a 1392x1072 video.

I was unaware that Intel dropped out of the modesetting work. I was aware
that xf86-video-intel was really out of date which is why I moved to
modesetting.
xf86-video-intel may work if you add Alder Lake PCI IDs similar to Tiger

Yes, that looks like a problem. Alder Lake is 12th Gen. and I don't supose
that a new backend is on the horizon, but my 10th Gen Comet Lake system had
much better performance and it should have had that issue, too.
Color me very confused.

VT_GETMODE isn't supposed to be used outside of --gpu-context=3Ddrm and=
