Build new kernel:

uname -a
NetBSD netbsd10 10.99.14 NetBSD 10.99.14 (MYKERNEL) #1: Thu May 15
17:57:27 MSK 2025
guest@slax:/mnt/sdb5/home/guest/amd64-obj/sys/arch/amd64/compile/MYKERNEL
amd64

and for now it seems to work, startx works, glxgears/celestia/stellarium works

Without some compositor I see artefacts here and here but mostly it works.

I wonder if there way to buid new mesa3d, with vdpau state tracker and new llvm?

Current mesa 19.1.17 + llvm 13 makes vaapi unusable (in mpv and in
cinelerra-gg I recompiled)

netbsd10$ mpv ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov
--hwdec=vaapi-copy -vo=x11
● Video  --vid=1  (hevc 3840x2160 59.9157 fps) [default]
● Audio  --aid=1  (pcm_s16le 2ch 48000 Hz) [default]
[vo/x11] Warning: this legacy VO has bad performance. Consider fixing
your graphics drivers, or not forcing the x11 VO.
