site: open-iov.org 2026 documentation update

- tools/site: Markdown-to-MediaWiki converter (tracked-paths-only link
  mapping, local-marker scan, About-message insert), WikiBot publisher
  with diff/check modes and publish manifest, live site auditor, image
  uploader, site-only page sources (landing page, About, index, sidebar,
  banner templates, About-message template).
- wiki: new public deep-dive sources (project status, install, FAQ,
  system overview, GSP and GSP-RM, execution frontier, host module,
  guest stack, UVM, physical backend, driver lifecycle, risc-v-gsp-rm-debugger,
  hardware/software matrix, HAAEEP, glossary); refreshed CUDA userspace
  status; corrected cross-document links; README rewritten for the new set.
- wiki/.publish-manifest.json records each published revision for rollback.

+
+## GPU, driver and virtualization
+
+| Term | Meaning |
+|---|---|
+| **BAR0 / BAR1 / BAR3** | PCI BAR windows of the GPU: register interface (16 MB), VRAM aperture (256 MB), instance/PRAMIN window. |
+| **CUDASW** | The family of NVIDIA user-space software between applications and the driver: `libcuda`, `libcudart`, the JIT compiler, the fatbinary loader, and friends. |
+| **Doorbell** | A register or memory location a driver writes to signal "new work is available" for a channel or queue. |
+| **mdev** | Mediated device: the kernel mechanism that turns a physical device into virtual instances (VFIO). |
+| **vGPU** | Virtual GPU: the device this project presents to a guest. |
+| **SRIOV / VF** | Single-root I/O virtualization / virtual functions (hardware partitioning). |
+| **IOMMU / SMMU** | Platform DMA translation and isolation (Intel VT-d / AMD-Vi / ARM SMMU). |
+
+## GSP, firmware and the RM
+
+| Term | Meaning |
+|---|---|
+| **GSP** | GPU System Processor: the embedded RISC-V (RV64IMAC) that runs firmware containing the Resource Manager. |
+| **GSP-RM** | The Resource Manager running on the GSP (the "self-hosted RM"). |
+| **RM / RM API** | NVIDIA's Resource Manager and the API used to allocate objects and issue controls. |
+| **RMCore** | The RM's object system: classes, handles, parents, methods. |
+| **resserv / resource server** | The RM component that owns allocation authority, privileges and lifetimes. |
+| **FWSEC** | Firmware security processor stage of the GSP boot sequence. |
+| **WPR** | Write-Protected Region: the VRAM area reserved for firmware. |
+| **MSGQ** | The GSP message-queue transport: shared-memory element rings with a page table, plus doorbells. |
+| **VGX version** | The version the guest announces during RPC negotiation; it selects message layouts. |
+| **Reply fidelity** | How completely an emulated reply matches what real hardware returns, as a ladder: status-only → coherent zeroed params → coherent values for consumed fields → exact values. |
+
+## Execution engines and memory
+
+| Term | Meaning |
+|---|---|
+| **CE** | Copy Engine: a DMA engine; also used for UVM's internal work. |
+| **GR** | The graphics/compute engine that executes shaders (graphics pipelines and CUDA kernels). |
+| **SEC2** | Secure copy engine used by UVM for protected operations. |
+| **GPFIFO** | GPU FIFO: a ring of entries, each pointing to a push buffer for a channel. |
+| **Push buffer** | A stream of method calls (engine commands) submitted via a GPFIFO. |
+| **PBDMA** | The push-buffer DMA engine in the host scheduler that fetches and executes push buffers. |
+| **QMD** | Queue Meta Data: the per-launch descriptor a GR channel reads to execute a kernel grid. |
+| **USERD** | Per-channel control block in VRAM: PUT/GET pointers and control state. |
+| **Runlist** | The scheduler's list of channels eligible to run. |
+| **TSG** | Time-Slice Group: channels sharing a scheduling slot. |
+| **Engine record / engine list** | The per-engine descriptors (kind, instance, class, client type) the driver walks after `GPU_GET_ENGINES`; each must be self-consistent or the driver rewrites the following allocation. |
+| **GMMU** | GPU Memory Management Unit: page tables, TLB, fault handling. |
+| **PDB** | Page Directory Base: root of a GPU page table. |
+| **PDE / PTE** | Page-directory entry / page-table entry. |
+| **UVM** | NVIDIA's unified memory module: VA spaces, page trees, faults, channel manager ([`UVM-in-the-Guest.md`](UVM-in-the-Guest.md)). |
+| **VA / PA / GPA / IOVA** | Virtual address / physical address / guest physical address / I/O virtual address. |
+| **vidmem / sysmem / aperture** | GPU local memory / system memory / how an address is qualified. |
+| **Semaphore / tracker** | A memory location written by the GPU to signal progress; UVM's tracker waits on it. |
+| **AMAPlib** | NVIDIA's shared "address mapping" library: swizzling, bank/channel mapping, aperture rules. |
+| **HAL** | Hardware abstraction layer: per-generation functions that program registers and formats. |
+| **Class list (classDB)** | The RM classes reported as supported; engine queries are filtered against it, so the class list, engine list and capability controls must agree. |
+
+## Method and tooling
+
+| Term | Meaning |
+|---|---|
+| **Host oracle / A-B harness** | The same query or deterministic workload run against a bare-metal host driver and inside the guest, then diffed — the reference for what the guest should have seen. |
+| **File virtual address (`libcuda+0x...`)** | An address relative to the start of a shared object file, as distinct from a runtime mapping or a disassembler program address. |
+| **Session (risc-v-gsp-rm-debugger)** | A recorded run of the firmware workbench — the unit of evidence ([`Riscv-GSP-RM-Debugger.md`](Riscv-GSP-RM-Debugger.md)). |
