  • Vulkan layer development patterns
  • Documented in docs/ARCHITECTURE_RESEARCH.md, docs/research/

Phase 2: Core Modules (100%)

Kernel Module

  • mvgal_core.c — DRM registration, /dev/mvgal0, 10 ioctls
  • mvgal_device.c — logical device, GPU enumeration, capability profile
  • mvgal_memory.c — DMA-BUF, unified virtual address space
  • mvgal_scheduler.c — 16-level priority queue, workload dispatch
  • mvgal_sync.c — cross-vendor fences, timeline semaphores
  • Vendor ops: AMD (TTM, DPM), NVIDIA (user-space shim), Intel (i915+xe), MTT

Userspace Library

  • GPU manager: sysfs scan, PCI enumeration, health monitoring
  • Memory manager: DMA-BUF, P2P, allocator, sync (2,576 LOC)
  • Scheduler: 7 strategies, load balancer, workload splitter (2,275 LOC)
  • Core API: init, context, strategy, stats, fences, semaphores
  • Logging: 22 functions, thread-safe, color, syslog, file, callbacks
  • Config: INI format, defaults, validation, callbacks
  • IPC: Unix socket, magic header, 11 message types

Public API Headers

  • 13 headers, 220+ public functions, fully documented

Phase 3: API Interception (100% for Vulkan, OpenCL, CUDA)

Vulkan Layer

  • Full dispatch-chain layer (vk_layer.c, ~1,205 LOC)
  • 17 intercepted functions across instance, device, queue, physical device
  • Physical device property caching for telemetry
  • Atomic submit counter, debug logging, log file support
  • Registered as implicit layer via JSON manifest

OpenCL Layer

  • LD_PRELOAD wrapper (cl_intercept.c, ~600 LOC)
  • Platform + device interception
  • NDRange kernel partitioning across GPUs
  • Registered via /etc/OpenCL/vendors/mvgal.icd

CUDA Shim

  • LD_PRELOAD wrapper (cuda_wrapper.c, ~1,340 LOC)
  • 40+ CUDA Driver and Runtime API functions
  • Kernel launch interception (cuLaunchKernel, cudaLaunchKernel)
  • Cross-GPU copy detection, memory tracking per GPU
  • 6 distribution strategies

OpenGL Preload

  • mvgal_gl_preload.c — intercepts glXSwapBuffers + eglSwapBuffers
  • Frame pacing telemetry injection
  • Works with Zink (Mesa OpenGL→Vulkan)

Phase 4: Testing (97.9%)

Suite Pass/Total

Stress benchmarks 9/10 (1 cosmetic)
Total 47/48

Phase 5: Documentation (100%)

  • 23 markdown files in docs/
  • All public API headers documented with Doxygen-style comments
  • Architecture diagrams, data flow diagrams
  • Per-vendor driver integration guide
  • Gaming, Steam, Rust development guides

Phase 6: Execution Engine + Rust (100%)

Execution Engine (src/userspace/execution/)

  • Frame session lifecycle: begin → submit → present
  • Migration plan generation (DMA-BUF, P2P, staging, mirror)
  • Steam/Proton profile generation

  • Callback system for health alerts

Phase 7: Tools, Steam, UI, OpenGL (100%)

CLI Tools

  • mvgal-info — GPU info, VRAM, temp, utilization, JSON output
  • mvgal-status — real-time bars, daemon check, --watch mode
  • mvgal-bench — memory BW, compute FLOPS, latency, sync overhead

Phase 8: Root Cleanup + CI (100%)

  • Moved generated/backup files to .archive/ (gitignored)
  • Both CI workflows set to workflow_dispatch (manual-only)
  • build/install.sh — generic installer using pkexec
  • build/cmake/toolchains/aarch64-linux-gnu.cmake — ARM64 cross-compile
  • All sudo replaced with pkexec in scripts

Remaining Work (~5%)
