- 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.

- Removed IOMMU group addition before vfio_register_emulated_iommu_dev() in nv_vgpu_mdev_create()
- Added IOMMUFD callbacks (bind_iommufd, unbind_iommufd, attach_ioas, detach_ioas) using kernel's vfio_iommufd_emulated_* functions
- Implemented VFIO ioctl handlers: GET_INFO, GET_REGION_INFO, GET_IRQ_INFO, SET_IRQS, MMAP
- Added config space read/write handlers at offset 0x70000000000
- Mmap handler for config space, BAR0 (emulation shadow), BAR1-5 (physical VRAM/registers)
- Interrupt handler for VFIO_DEVICE_SET_IRQS (DATA_EVENTFD, DATA_NONE, DATA_BOOL)
- Added udev rules for vfio group permissions
- Created stack_manager.sh unified tool
- Fixed mdev remove crash with deferred cleanup in vfio_device_release callback
- Kernel 6.8+ IOMMUFD compatibility
- QEMU launches successfully with vGPU passthrough
