dmesg (freebsd 14.0-rc2)

Hey all,

I've been noticing for a while now (maybe a year+) that there are periodic
"stutterings" that happen on my Framework Laptop (Gen 1, Batch 6) running
TigerLake-LP GT2 [Iris Xe Graphics] for graphics. This usually only happens
only on sway/Wayland, and not as much (or at all) on i3/Xorg. I'm currently
running FreeBSD 14.0-RC2, but I've experienced the issue throughout the 13.X
series as well. Just opening up this bug report since I thought I posted about
this somewhere before but I can't find it at the moment. The "stuttering"
effect is best described by imagining what happens to a garbage collected
application when the garbage collector periodically runs. There is a "freeze
period" that happens and a few seconds later everything resumes again. This may
or may not be some sort of graphical error recovery mechanism kicking in, but
I'm not sure. I do see this in my dmesg that may be of interest, but I don't
necessarily see this message printed out every single time the freeze occurs.

drmn0: [drm] *ERROR* Atomic update failure on pipe D (start=29397 end=29398)
time 996 us, min 1431, max 1439, scanline start 1365, end 1468

I'm attaching my current dmesg output for FreeBSD 14.0-RC2.

- Jonathan
