From 535b6769709eb22333af26269f1b16f37adce4db Mon Sep 17 00:00:00 2001 From: yumekiru <338525349+yumekiru@users.noreply.github.com> Date: Wed, 28 Oct 2026 21:21:11 -0400 Subject: Import experimental NS2 support and accumulated GPU fixes Bring the NS2 patch and local follow-up fixes onto Eglantine master. Includes native graphics services, instruction translation, syncpoint cancellation acknowledgement, texture handling and diagnostics. Experimental checkpoint; not ready to merge. The original Eden build passed, but this rebased branch has not been built or tested.
