Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers https://git.vgpu.io/open-iov.git/atom?h=master 2026-10-08T15:53:20+00:00 2026-10-08T15:53:20+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-08T15:53:20+00:00 urn:sha1:2ee4fe8f43b0dc3e080c91931eadade1fd636c27 Sweep of the 155 tracked C/Python/shell files under userspace/ (excluding the MIT-licensed vendored userspace/extern/), tools/ and scripts/ that had no per-file license identifier. Each gains the minimal two-line header in the area's existing form: 'SPDX-License-Identifier: BSD-3-Clause' plus 'Copyright (c) 2026 Open-IOV contributors'; shebang and coding lines stay first. No other content touched. kernel/** is deliberately out of scope (recorded as a follow-up in CODESTD-REPORT-2026-10-08.md): its SPDX coverage and MODULE_LICENSE normalization need their own GPL-2.0 pass. 2026-09-29T13:51:22+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T13:51:22+00:00 urn:sha1:8cb84c25cb55ac61e423ee39b7dcb6420d302f96 The client times out the context-init counter wait in ~30 s; the previous poll loop spent ~50 s on chan_dump round-trips before injecting. Count the per-channel first-pump log lines straight from dmesg every 0.5 s instead. 2026-09-29T13:45:19+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T13:45:19+00:00 urn:sha1:497d4d8f333fb750e365e4ff0a32764ed008548b 2026-09-29T13:29:02+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T13:29:02+00:00 urn:sha1:6135508cc3b043c35d2e0617870f35b18b29b79c Restart the VM, push the guest tools, start cdt holding on failure, wait for the 20 GR channels, register/pin the completion counters and arm scanerr.py, so each iteration is a single command. scanerr now loops over scanner hits until a hit carries a non-zero RM error record.
