* Merge and remove the pre-reboot flat documents, preserving their still-useful
material in the structured tree: debugging workflows and the EPT-livelock
case study (05-operations/02), performance microbenchmarks and A/B
methodology (05-operations/01), the version-upgrade runbook
(05-operations/02 section 4, with corrected host/guest framing), kernel-code
pitfalls (07-developers) and the OpenRM build/load order
(03-architecture/06 section 7). The remaining legacy files were verified
redundant and removed.
* docs/README now records where each migrated topic lives.
* Portability: the config YAML files are called out as design targets that no
code reads yet, with what adding support actually requires today.
* Getting started: the OpenRM step is marked optional (native vGPU-management
workflows only; the emulated path uses the distro driver).
* tools docs: rmtool/rmtop marked as planned, pointing at the implemented
tools/rmq subset.
* wiki: new CUDA-Userspace-Driver deep-dive page (public-safe, links the
canonical userspace/cuda analysis) and index update.
* scripts/check-docs-links.py plus a CI step so relative links cannot rot.
* STATE.md references to removed documents repointed.

Open-IOV virtualizes NVIDIA GPUs so that unmodified guest drivers run with
real GPU functionality - CUDA first, 3D and video to follow - on unmodified
hosts, without a proprietary vGPU license and without patching any driver,
firmware or hypervisor.
Core principle: emulate the interface, pass through the work.
kernel/ open-iov-vfio.ko - host VFIO mdev driver: virtual GPU device
(PCI config space, BAR shadows, MSI-X), GSP boot emulation,
GSP-RM message-queue/RPC emulation, memory model (GPU-VA to
guest-PA discovery) and the semaphore-completion service that
advances guest UVM progress.
userspace/ libiov.so management API and examples.
tools/ guest diagnostics, firmware analysis wrappers, RM probes.
scripts/ stack manager, VM harness, build/load/test automation.
config/ hardware/version profiles (the portability surface).
docs/ documentation tree - start at docs/README.md.
wiki/ long-form firmware and protocol deep dives.
Status: initialization works end to end for a stock 570.144 Linux guest on
Turing (TU104): driver probe, nvidia-smi, the full GSP-RM control battery,
object creation and the early CUDA/UVM start-up path. GPU work forwarding -
the step that makes CUDA kernels execute on real hardware - is the active
work item; see docs/04-implementation/01-known-knowns-and-unknowns.md.
