kernel: Fix FIFO table fortify_panic + GSP boot-state reset on queue death + ISO fbRegion

2026-09-21T23:04:05+00:00

- gsp_rm_handle_fifo_device_table: read baseIndex from the queue element buffer (req_data + hdr), not past the local 24-byte header struct - FORTIFY proved the old memcpy always overflows -> fortify_panic killed gsp_emu_0 mid RmInitNvDevice (guest timed out on fn 76). - gsp_emu_clear_boot_state: clear WPR2/RISCV/mailboxes/stage tracker and reset GSP-RM queue state. Turing guests produce no observable BAR0 writes on unload, so the next probe's _kgspBootGspRm failed with 'unexpected WPR2 already up'. Trigger on ENGINE reset and on detected queue death (insane writePtr jump / garbage element signature). - GspStaticConfigInfo fbRegion[0].supportISO=1: memmgrCalcReservedFbSpace asserts some region supports ISO 'even with no display'; without it kdispStateInitLocked couldn't allocate clientChannelTable. - .gitignore: scripts/git-push-vgpu.sh (local per-machine helper)

kernel: GSP-RM msgq emulation + TU104 hardware tables (GET_GSP_STATIC_INFO, GSP_RM_CONTROL)

2026-09-21T22:01:55+00:00

Implements the GSP-RM reply content layer for the msgq RPC channel: - kernel/gsp_rm_emulation.c/h: GSP-RM msgq emulation engine - Queue chain discovery (libos args → RMARGS → GSP_ARGUMENTS_CACHED) - Status queue link + GSP_INIT_DONE emission - Command queue polling + RPC dispatch - SET_GUEST_SYSTEM_INFO version negotiation (VGX 41.12) - GET_GSP_STATIC_INFO(65) with 1656-byte GspStaticConfigInfo - GSP_RM_CONTROL(76) sub-command dispatch: - FIFO_GET_DEVICE_INFO_TABLE (0x20801112) - INTERNAL_INTR_GET_KERNEL_TABLE (0x20800a5c) - GPU_GET_CONSTRUCTED_FALCON_INFO (0x208001b0) - INTERNAL_GET_DEVICE_INFO_TABLE (0x20800a40) - kernel/gsp_rm_tu104.h: TU104 hardware tables - 12-entry FIFO engine table (GR0, CE0-4, NVDEC0-1, NVENC0, SEC2, NVJPG, SW) - 8-entry interrupt table (from intr_phys_tu102.c) - 1-entry constructed falcon table (FBFLCN) - 11-entry internal device info table - GspStaticConfigInfo layout (1656 bytes, ABI-verified offsets) - Data from NVIDIA driver material (ext-tree) + hwref/turing/tu104 - tools/rmq/: Userspace RM API client (oracle for ground-truth tables) KNOWN ISSUE: gsp_rm_send crashes (fortify_panic) on multi-element messages when reply data exceeds one 4096-byte queue element. Affects cmd 0x20800a41 (paramsSize=8204). Multi-element splitting is the next fix.

Untrack userspace test binary (build artifact)

2026-09-21T17:06:58+00:00

Untrack decompiled GSP sources (decompiled_*.c at version-dir top level)

2026-09-21T15:31:20+00:00

The firmware/**/decompiled/ ignore covered the subdirectory but not the decompiled_*.c handler files directly under firmware///. GSP-derived decompilation output is not tracked in git (regenerable with the analysis scripts in the same directory).

Make repo fully path-portable and add reproducible installer

2026-09-21T15:09:36+00:00

- 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.

repo: Untrack binaries/vendor/wrapper layers, add .gitignore + NVIDIA patches

2026-09-21T14:40:43+00:00

Restructure for clean mirroring to git.vgpu.io/open-iov.git: - Untrack GSP firmware blobs and decompiled output (firmware/**/*.bin, firmware/**/decompiled/) - large, license-restricted NVIDIA binaries. Analysis scripts, docs, and address maps remain tracked. - Untrack nvidia-open-gpu-kernel-modules submodule; our delta against upstream tag 610.57.04 is now tracked as a patch series in patches/nvidia/ and applied by install.sh after cloning. - Untrack kernel build artifacts (*.o, *.ko, Module.symvers, ...). - Untrack Ghidra project databases (*.rep/, *.gpr) - scripts remain. - Untrack VM images (*.iso, *.img, *.qcow2) and compiled helper binaries. - Drop git-lfs (.gitattributes) - no large objects remain in git. - Local QEMU-wrapper layers (scripts/vgpu_vm.py, qemu_control.py, qemu_harness.sh) are gitignored: the repo is hypervisor-management neutral (libvirt, raw QEMU all work). All files remain on disk; only git tracking changes. No source code modified.
