From 90ab9baa309ae3c54d371546872c918c4c801920 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Tue, 10 Nov 2026 05:25:15 -0500 Subject: wiki: 2026-11-10 status refresh - guest GL draws execute on the physical GPU Refresh STATE-CURRENT, the Main Page and the status/frontier pages: the GSP event-IRQ fix completes swaps; the 2D path is green end-to-end; the guest's real GL draws now forward and execute on the physical GPU (work_gr backend_ok=9); the draw writes 0 pages because its constant-buffer (MVP) page is unresolved and forced to the seed page; the MME front-end defer, GR stale-wedge and the X DDX get-word/notifier completion remain.
