- install.sh: one-command fresh-Ubuntu reproduction (deps, NVIDIA clone
+ patch, GSP firmware fetch from linux-firmware.git with objcopy
.fwimage extraction + MD5 verify, ordered build, host config, load,
mdev creation). Wrapper-neutral: works with libvirt/raw QEMU.
- patches/nvidia: regenerated path-independent patch (KBUILD_EXTRA_SYMBOLS
resolved via $(src)/$(CURDIR) relative to the NVIDIA tree).
- scripts/stack_manager.sh and helper scripts auto-detect repo root
(OPEN_IOV_ROOT override); no hardcoded developer paths anywhere.
- firmware analysis scripts use script-relative paths (also fixes stale
firmware/570-GSP references); docs/wiki updated to $OPEN_IOV_ROOT.
- .github/workflows/ci.yml updated for standalone repo layout; firmware
fetched from linux-firmware in CI.
- Untrack remaining kbuild artifacts (Module.symvers, modules.order,
*.o.d); gitignore them.
- STATE.md: live project state, limitations, fixed/open bugs.
- README.md: rewritten for clone-and-run reproducibility.

- Firmware Analyzer: Runtime firmware signature computation (CRC32, SHA256) and pattern-based RPC handler address discovery
- Dynamic RPC Dispatcher: Version-aware dispatch with native firmware handlers (550/560/570/580) and emulation fallback
- Hardware Architecture Layer: Turing, Ampere, Blackwell configs with BAR layouts, doorbell offsets, MSI-X vectors
- Driver Version Adaptation Layer: Feature detection per driver version
- Declarative YAML configs for hardware (turing/ampere/blackwell) and versions (550/560/570/580)
- Kernel unit tests for GSP emulation (gsp_emulation_test.c)
- Test infrastructure scripts (test_gsp_emu.sh, test_guest_driver.sh, test_cuda_workloads.sh, test_graphics_workloads.sh, test_windows_guest.sh, test_vgpu_stack.sh)
- Updated kernel Makefile with new source files

- New kernel/gsp_emulation.h: GSP emulation context and API
- New kernel/gsp_emulation.c: Per-mdev emulation thread with:
- Adaptive polling of doorbell at BAR0+0x110C00
- Shared memory RPC processing (4KB at BAR0+0x1000)
- Dispatch for all 12 RPC types via firmware-decompiled handlers
- MSI-X completion interrupt injection via eventfd
- Statistics tracking (processed/failed RPCs, latency)
- Modified kernel/main.c: Integrate gsp_emu_init/cleanup in device lifecycle
- Modified kernel/Makefile: Add gsp_emulation.o to build
- Modified kernel/gsp_rpc_client.h: Export gsp_rpc_emulation_set/is_enabled
