open-iov.git/tools/guest-diag/wall2/guest_words.sh, branch master Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers https://git.vgpu.io/open-iov.git/atom?h=master 2026-10-25T12:05:18+00:00 wall-2 session-77: vkCreateDevice PASSES - r682 0x7E event validated live (registered slot 13, EVPOST rc=0) and the completion word found/driven: the main-thread wait reads a u32 at +0x80 of a 16 KB rw-s /dev/nvidiactl notification mapping (should-wait = word != 1); a host write of 1 via the guest RAM file (PA from pagemap, file offset PA-0x80000000 above 4G) flips the wait and vkCreateDevice returns success (VKDEVICE ok family=0) - reproduced 3x (r683 manual, r684 nudger, r684d probe+single-word). Tools: t79.py (wait-chain resolver), guest_words.sh, nudge.sh; README-session77.md records the recipe, the residual guest event-dispatch gap (records consumed, notification word not written), and the -4/gdb-attach cautions. 2026-10-25T12:05:18+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-25T12:05:18+00:00 urn:sha1:6baa2135a7815776a114e8afe883e68883d3f31b
