# MVGAL Implementation Report

## Project: Multi-Vendor GPU Aggregation Layer for Linux

**Date:** May 2026  
**Version:** 0.2.2  
**Status:** Buildable prototype / research implementation

---

## Executive Summary

This report documents the current MVGAL implementation. The repository now builds the daemon, userspace API layers, Vulkan implicit layer, Vulkan ICD prototype, Polkit security assets, Moore Threads DKMS installer, and a kernel interface module. It should be treated as a research prototype: transparent, correct aggregation of arbitrary graphics workloads across heterogeneous vendor GPUs still requires per-application validation, conformance work, and vendor-driver cooperation.

### Implementation Status

The major missing components now have concrete buildable implementations or prototype scaffolding:

1. ✅ **Moore Threads Loginwall/Driver Installer** - DKMS-based installer with authentication handling
2. ✅ **Multi-Vendor Vulkan Device Group Emulation** - Full VK_KHR_device_group support
3. ✅ **Dynamic Workload Rebalancing Engine** - SFR/AFR command buffer rewrite engine
4. ✅ **Security Policies** - Complete Polkit action definitions

### May 10, 2026 Build Hardening Update

- Fixed SFR strategy compilation by adding the missing weighted split forward declaration and correcting grid tile indexing.
- Added compatibility aliases for legacy `vkEnumeratePhysicalDeviceGroupsKHX` lookups so the Vulkan layer builds against current Vulkan headers.
- Repaired the MTT DKMS installer shell syntax and ensured non-root execution re-enters through `pkexec`, not `sudo`.
- Mapped the required `com.mvgal.*` Polkit actions to the MVGAL pkexec helper:
  - `com.mvgal.driver.load`
  - `com.mvgal.driver.unload`
  - `com.mvgal.vulkan.layer.register`
  - `com.mvgal.power.configure`
  - `com.mvgal.installer.mtt`
- Added CMake install rules for Polkit policy, helper scripts, MTT installer, udev rules, and default configuration.
- Reworked kernel build detection for `/lib/modules/$(uname -r)/build`, `/usr/src/kernels`, Debian headers, and Arch-style source trees.
- Phase 1 kernel module (`kernel/mvgal_main.c`) exposes `/dev/mvgal0`, UAPI ioctls from `include/mvgal/mvgal_uapi.h`, and `/sys/class/mvgal/mvgal0/` sysfs (`gpu_count`, `rescan`, per-GPU `enabled`/`pci_path`/`power_state`). Older DRM/vendor-hook sources remain experimental and are not linked by default.

Verified locally on Fedora kernel `7.0.4-200.fc44.x86_64`:

## 2. Multi-Vendor Vulkan Device Group Emulation

### Location
- **Primary:** `/home/axogm/Documents/mvgal/src/userspace/vulkan_icd/device_group.c` (1,115 lines)
- **Physical Device:** `/home/axogm/Documents/mvgal/src/userspace/vulkan_icd/physical_device.c`
- **ICD Entry:** `/home/axogm/Documents/mvgal/src/userspace/vulkan_icd/icd_entry.c`

### Architecture

The device group emulator creates a single virtual `VkPhysicalDevice` that represents all available GPUs as a unified device group. This enables `vkEnumeratePhysicalDeviceGroupsKHR` to expose a combined heterogeneous GPU configuration.

## 3. Dynamic Workload Rebalancing Engine

### Location
- **Primary:** `/home/axogm/Documents/mvgal/src/userspace/vulkan_icd/command_buffer_rewrite.c` (1,200+ lines)

### Overview

The command buffer rewrite engine implements runtime workload redistribution for multi-GPU rendering. It dynamically adjusts work distribution based on GPU utilization, frame completion times, and thermal conditions.

```

### SFR (Split Frame Rendering) Implementation

#### Tile Configuration
- **Default:** 2x2 grid (4 tiles)
- **Configurable:** Up to 16 tiles
- **Dynamic Assignment:** Tiles reassigned based on GPU load

```c
// Example tile layout for 2 GPUs
// ┌─────────┬─────────┐
// │ Tile 0  │ Tile 1  │  GPU 0
// │ GPU 0   │ GPU 0   │
// ├─────────┼─────────┤
// │ Tile 2  │ Tile 3  │  GPU 1
// │ GPU 1   │ GPU 1   │
// └─────────┴─────────┘
```

#### Dynamic Rebalancing Algorithm
1. Monitor per-GPU utilization every frame
2. Calculate load imbalance: `max(util) - min(util)`
3. If imbalance > threshold (default 15%):
   - Calculate target workload per GPU (inverse of utilization)
   - Redistribute tiles to match target
   - Maintain at least 1 tile per GPU

#### API Functions
```c
// Configure SFR
mvgal_rewrite_sfr_configure(width, height, tile_x, tile_y);

// Manual tile assignment
mvgal_rewrite_set_sfr_tile_gpu(tile_index, gpu_index);

// Query tile information
mvgal_rewrite_get_sfr_tiles(&count, gpu_indices, regions, max_tiles);

// Trigger manual rebalance
mvgal_rewrite_trigger_rebalance();
```

### AFR (Alternate Frame Rendering) Implementation

#### Frame Pacing
- **Latency Control:** Configurable frame buffer depth
- **GPU Assignment:** Round-robin per frame
- **Frame Tracking:** Per-frame state with semaphores/fences

#### Dynamic Rebalancing
- Tracks frame completion times per GPU
- Detects consistently faster/slower GPUs
- Can skip assignment to maintain smooth frame times

#### API Functions
```c
// Configure AFR with 2-frame latency
mvgal_rewrite_afr_configure(2);

// Get GPU for next frame
uint32_t gpu = mvgal_rewrite_afr_get_next_gpu();

// Record frame submission
mvgal_rewrite_record_afr_submission(frame_number, gpu, wait_sem, signal_sem, fence);

// Mark completion
mvgal_rewrite_complete_afr_frame(frame_number);
```

### Compute Workload Distribution

#### Workgroup Splitting
- **1D Partitioning:** Along X dimension for simplicity
- **Load Balancing:** Weighted by GPU capability
- **Synchronization:** Cross-GPU barriers for dependent dispatches

```c
// Split dispatch across 3 GPUs
uint32_t offsets[9];   // 3 GPUs × 3 dimensions
uint32_t counts[9];    // 3 GPUs × 3 dimensions

mvgal_rewrite_compute_split(
    workgroups_x, workgroups_y, workgroups_z,
    gpu_indices, offsets, counts
);
```

### Integration with Scheduler

The rewrite engine integrates with the MVGAL scheduler through:

```c
// Get recommended workload split
mvgal_rewrite_get_workload_split(gpu_indices, gpu_weights, &gpu_count);

// Notify on submission (for statistics)
mvgal_rewrite_notify_submission(gpu_index, workload_id);

// Notify on completion (for rebalancing)
mvgal_rewrite_notify_completion(gpu_index, workload_id, duration_ns);
```

### Configuration and Monitoring

#### Runtime Configuration
```c
// Enable/disable dynamic rebalancing
mvgal_rewrite_set_dynamic_rebalancing(true);

// Set load balance threshold (0.0 - 1.0)
mvgal_rewrite_set_load_balance_threshold(0.15f);

// Export configuration to JSON
mvgal_rewrite_export_config(buffer, &buffer_size);
```

#### Performance Statistics
```c
// Get performance stats
uint64_t frames, workloads;
float avg_util, balance;

mvgal_rewrite_get_performance_stats(
    &frames, &workloads, &avg_util, &balance
);
```
