wiki: 2026-11-09 evening refresh 2 - forced GLX reaches glcore; windowed GL waits on kernel kick completion
Refresh STATE-CURRENT, the Main Page and the status/frontier pages: with
SDL_VIDEO_X11_FORCE_EGL=0 the windowed GL path selects libnvidia-glcore,
but the minimal glxgears hangs in the glcore kick wait (poll on the
per-slot /dev/nvidia-modeset fd) while the host completes the beef
notifier memory. The X DDX get-word/notifier completion, the DDX 4 GB
sysmem footprint and physical dispatch of the GL draws remain. Published
to open-iov.org.
