Model loading was solved by bypassing the GPU entirely (CPU-side memset/memcpy on host-mapped memory). However, **actual GPU compute kernels** (inference) also trigger KIQ/TLB operations and crash identically. **Next step**: Try Vulkan backend (radv driver) which uses a different GPU command path that does NOT go through KFD/KIQ. + +--- + +## 2.

The kernel's KFD driver still cleans up asynchronously when file descriptors are closed, which CAN still trigger a KIQ timeout — but with `gpu_recovery=1` active, the system survives (GPU becomes temporarily unusable). + +--- + +## 7. Known Issues & Workarounds + +### Issue 1: KIQ Fence Timeout After Process Exit + +**Symptom**: `amdgpu: timeout waiting for kiq fence` in kernel log. +**Cause**: KFD queue cleanup on the BC-250's KIQ ring hangs. +**Impact**: GPU unusable until reboot (system stays up with `gpu_recovery=1`). +**Workaround**: Use long-running daemon processes. Don't frequently start/stop HIP programs. + +### Issue 2: Only One HIP Session Per Boot + +**Symptom**: Second HIP process hangs at `hipGetDeviceCount()`. +**Cause**: First process exit corrupts KIQ state; GPU doesn't fully recover. +**Workaround**: Design workloads as single long-running process. Reboot between sessions. + +### Issue 3: hpd IRQ Errors at Boot + +**Symptom**: `[drm] *ERROR* Failed to clear hpd(rx) source=X on init` +**Cause**: Display hotplug IRQ on headless system (no monitor connected). +**Impact**: Cosmetic only, no functional effect. +**Fix**: `amdgpu.dc=0` in kernel parameters disables display controller. + +### Issue 4: rocm-smi Crashes GPU + +**Symptom**: Running `rocm-smi --showhw` causes KIQ timeout. +**Cause**: SMI queries trigger GPU management commands through KIQ. +**Workaround**: **Never run `rocm-smi`** on this GPU. Use `rocminfo` for device info instead. + +### Issue 5: Compute Units Reported as 12 (not 24) + +**Symptom**: `hipGetDeviceProperties` reports 12 CUs. +**Cause**: HIP reports shader engines × CU arrays = 12. Real hardware has 24 CUs (4 arrays × 2 SIMDs × ~3 CUs). KFD topology shows `cu_per_simd_array=10`, `simd_arrays_per_engine=2`, `array_count=4`. +**Impact**: None — actual compute throughput matches the 24 CU hardware. + +--- + +## 8.

When the code calls `cudaMemset` or `cudaMemcpy` on this memory, the GPU processes it through its command queue → KIQ ring. But since the memory IS host memory, plain `memset()`/`memcpy()` from the CPU works identically — without touching the GPU at all. This completely removes all GPU involvement during the model loading phase (tens of thousands of tensor operations), while GPU compute kernels still run on the GPU for actual inference. + +### Previous Root Cause Chain (Process Exit) + +``` +HIP process exits + → KFD driver runs kfd_process_destroy_wq (async worker) + → Unmaps compute queues from GPU + → Sends unmap command through KIQ ring + → KIQ ring on BC-250 hangs (hardware/firmware bug) + → "timeout waiting for kiq fence" + → Without gpu_recovery=1: system freeze (shared RAM corruption) + → With gpu_recovery=1: GPU unusable, system survives +``` + +### Crash #11: Inference (GPU Compute Kernels) + +**Status: UNSOLVED — this is the current blocker.** + +Strategy C fully solved model loading (zero KIQ), but the first actual **GPU compute operation** (inference/image generation) triggers the same KIQ/TLB crash. + +#### Crash #11 Timeline + +``` +05:50:26 Model loaded successfully (Z-Image architecture, ~7.6 GB) +05:50:26 GPU status: ZERO KIQ timeouts, fully stable +05:54:46 WebSocket client connected (user opened Web UI) +05:55:18 Job queued: txt2img | prompt="blonde woman" | 512x1024 | steps=8 +05:55:18 [SDWrapper] Calling generate_image()... ← LAST APP LOG +05:55:33 KERNEL: "timeout waiting for kiq fence" (15s after generate) +05:55:33 KERNEL: "TLB flush failed for PASID 32770" +05:55:46 KERNEL: "timeout waiting for kiq fence" (second timeout) +05:55:46 System crash → hard reboot +``` + +#### Analysis + +- Model loading is 100% stable with Strategy C (CPU-side memset/memcpy) +- But `generate_image()` invokes actual **HIP compute kernels** on the GPU +- These kernels trigger TLB flushes via the KIQ ring — same failure mode +- The 15-second gap (05:55:18 → 05:55:33) matches the KIQ timeout threshold +- This proves that **any non-trivial GPU compute** triggers the KIQ bug + +#### Root Cause Chain (Inference) + +``` +generate_image() called + → GGML builds computation graph (matmul, attention, conv2d, etc.) + → ggml_backend_cuda_graph_compute() dispatches HIP kernels + → First kernel launch requires GPU page table setup for compute buffers + → GPU issues TLB flush via KIQ ring + → KIQ ring hangs on BC-250 (same hardware bug as model loading) + → "TLB flush failed for PASID 32770" + → "timeout waiting for kiq fence" + → System crash (shared RAM, no safe GPU reset) +``` + +#### Key Difference from Model Loading + +| Phase | Operations | Strategy C Fix | GPU Involvement | +|-------|-----------|---------------|-----------------| +| Model Load | memset, memcpy (tensor init/copy) | Replaced with CPU ops | **None** (bypassed) | +| Inference | matmul, conv2d, softmax, attention | Cannot replace with CPU | **Required** (actual compute) | + +Strategy C works for loading because memset/memcpy are "dumb" operations that don't need GPU. But inference requires actual GPU matrix multiplications — these CANNOT be replaced with CPU equivalents while staying on the HIP backend. + +#### Next Steps: ROCm Inference Strategy Cascade + +The goal is to get ROCm/HIP inference working on BC-250, no matter what it takes. The strategies below are ordered by investigation priority. + +| # | Strategy | Approach | Effort | Rationale | +|---|----------|----------|--------|----------| +| D | **Pre-fault all pages before compute** | Use `hipMemPrefetchAsync` or `mlock`/`madvise` to force all page table entries into the GPU TLB before any kernel launches | Medium | If all pages are already mapped, the GPU should NOT need TLB flushes during compute. The KIQ hang may only happen on cold TLB misses. | +| E | **Minimal compute test** | Run a tiny HIP kernel (e.g. 1 element, single thread) on host-mapped memory after model load | Low | Determines if ALL GPU compute crashes or only large/sustained workloads. If tiny kernels survive, we can progressively increase size to find the threshold. | +| F | **Alternative TLB invalidation** | Set `amdgpu.noretry=1` (changes page fault to immediate kill instead of retry/flush) and try `HSA_OVERRIDE_GFX_VERSION=10.1.0` with xnack variants | Low | Different noretry/xnack combos may change how the GPU handles TLB misses — possibly avoiding KIQ entirely. | +| G | **Increase KIQ timeout** | Patch `amdgpu` module or use debugfs to increase KIQ fence timeout beyond 15s | Medium | The operation may NOT be hanging forever — it may just be slow. If the timeout is 60s+ the flush might complete. Current `lockup_timeout=120000` only affects general lockup, not KIQ specifically. | +| H | **Kernel driver source patch** | Modify `amdgpu_gmc_flush_gpu_tlb_pasid()` in the kernel to use MMIO-based TLB invalidation instead of KIQ for gfx1013 | High | RDNA1/gfx10 supports MMIO register-based TLB invalidation as a fallback. Bypasses KIQ ring entirely. Requires building a custom kernel module. | +| I | **Graph-level CPU fallback** | Intercept `ggml_backend_cuda_graph_compute()` to run compute graphs on CPU backend when on BC-250 while keeping tensors in host-mapped GPU memory | High | Model stays loaded via ROCm/HIP (working), but compute is done by CPU. ROCm is still running the show — just delegating the math. | +| J | **hipGraph / stream serialization** | Use `hipGraphLaunch` or extreme stream serialization (`HIP_LAUNCH_BLOCKING=1` + single-op batches) to minimize concurrent TLB pressure | Medium | Multiple concurrent kernel launches may overwhelm the KIQ ring. Forcing single-kernel-at-a-time execution may let each TLB flush complete before the next. | + +**Recommended execution order: E → D → F → G → H → J → I** + +Strategy E (minimal compute test) should be done first — it takes 5 minutes and tells us whether the problem is ALL GPU compute or only sustained/large workloads. This fundamentally determines which subsequent strategies are viable. + +--- + +## 13.

Action Plan — Phased Approach + +### Phase 0: Quick Test — LTS Kernel Boot (15 minutes) +**Rationale**: The 6.12.68 LTS kernel may have a subtly different amdgpu module.

Run sustained compute test (larger workload) +# 5. Check KIQ timeouts +``` + +**Decision gate**: If LTS kernel eliminates KIQ timeouts → use it. If not → proceed to Phase 1. + +### Phase 1: Custom amdgpu Kernel Module (2-4 hours) +**Rationale**: The definitive fix. Forces MMIO TLB invalidation for gfx1013. + +```bash +# 1. Get kernel source for current kernel +pacman -S linux-cachyos-headers asp +asp export linux-cachyos # or download kernel source matching 6.18.8 + +# 2. Extract just the amdgpu module source + +# 3. Apply patch to gmc_v10_0.c: +# - Force MMIO path for IP_VERSION(10, 1, 3) +# - Set flush_pasid_uses_kiq = false for gfx1013 + +# 4. Build only the amdgpu.ko module (not full kernel) + +# 5. Install as override: +sudo cp amdgpu.ko.zst /lib/modules/$(uname -r)/updates/amdgpu.ko.zst +sudo depmod -a + +# 6. Reboot and test +``` + +### Phase 2: Sustained Compute Validation (1-2 hours) +After Phase 1 module is loaded: + +```bash +# 1. Run hip_vector_add — baseline +# 2. Run progressively larger workloads (matmul, attention, conv2d) +# 3. Run multiple iterations without reboot +# 4. Load sd.cpp model via HIP backend (CPU-side ops, Strategy C) +# 5. Attempt inference (the operation that crashed in Crash #11) +# 6. Monitor for KIQ timeouts throughout +``` + +### Phase 3: Full Stack Validation (2-4 hours) +If Phase 2 passes — see [ZImage_Documentation.md](ZImage_Documentation.md) for Z-Image setup: + +```bash +# 1. Start Z-Image server (bash ~/start-zimage.sh) +# 2. Load model via API (see ZImage_Documentation.md Section 6) +# 3. Generate images at 512×512, 512×1024, 1024×1024 +# 4. Compare performance vs Vulkan backend (~79s reference) +# 5. Stress test: 10+ consecutive generations +# 6. Kill and restart server (test KIQ on process exit) +``` + +### Phase 4: PyTorch / ML Framework (4-8 hours, if needed) +Only if PyTorch/ML is needed beyond sd.cpp: + +```bash +# 1. Build PyTorch from source with PYTORCH_ROCM_ARCH=gfx1010 +# 2. Build rocBLAS, hipBLAS from source (should work on ROCm 7.2) +# 3. Test basic tensor operations +# 4.

BC-250's KIQ implementation has a hardware/firmware bug that causes fence timeouts on these operations. | +| **MMIO path** | The same function has a fallback path using direct MMIO register writes (`WREG32_RLC_NO_KIQ`/`RREG32_RLC_NO_KIQ`). This path is slower but 100% reliable on BC-250. Vulkan (RADV/Mesa) uses this same hardware path and works flawlessly. | +| **gfx1013 scope** | The `IP_VERSION(10, 1, 3)` check ensures ONLY BC-250/Cyan Skillfish is affected. All other GPUs continue using the fast KIQ path. | +| **PASID flush** | The `flush_pasid_uses_kiq` flag controls a separate code path in `gmc_v10_0_flush_gpu_tlb_pasid()`. Disabling it makes PASID-based TLB flushes also avoid KIQ, preventing crashes during KFD (compute) process cleanup. | + +### 20.4 Build Process + +``` +Source: linux-6.18.8 (kernel.org vanilla) +Config: Copied from running CachyOS kernel (/proc/config.gz) +Localver: -3-cachyos (matched via localversion.10-pkgrel + localversion.20-pkgname) +Symvers: Copied from /usr/lib/modules/6.18.8-3-cachyos/build/Module.symvers +Build cmd: make -j12 M=drivers/gpu/drm/amd/amdgpu modules +Vermagic: 6.18.8-3-cachyos SMP preempt mod_unload (MATCHES running kernel) +Signing: Not signed (CONFIG_MODULE_SIG_FORCE=n, LOCK_DOWN_FORCE=NONE) +MODVERSIONS: Disabled (no CRC mismatch risk) +``` + +### 20.5 Installation + +| Step | Command | Result | +|------|---------|--------| +| Backup | `cp amdgpu.ko.zst amdgpu.ko.zst.original` | 5.0M backup created | +| Strip | `strip --strip-debug amdgpu.ko` | 621M → 28M | +| Compress | `zstd -19 amdgpu.ko` | 28M → 4.3M | +| Install | `cp amdgpu.ko.zst /usr/lib/modules/.../amdgpu/` | Replaced | +| Depmod | `depmod -a` | Module deps updated | +| Restore | `/home/dars/kernel-build/restore_original_module.sh` | Available | + +### 20.6 Files Created + +| File | Purpose | +|------|---------| +| `/home/dars/kernel-build/linux-6.18.8/` | Full kernel source tree with patch | +| `/home/dars/kernel-build/bc250-kiq-fix.patch` | Unified diff of the patch | +| `/home/dars/kernel-build/restore_original_module.sh` | Restores original module | +| `/home/dars/VibeROCm/post_reboot_test.sh` | 8-test validation suite | +| `/usr/lib/modules/.../amdgpu.ko.zst.original` | Backup of stock module | + +### 20.7 Expected Results After Reboot + +| Symptom | Before Patch | Expected After | +|---------|-------------|----------------| +| KIQ fence timeout after HIP process exit | **5+ timeouts, GPU dies** | **Zero timeouts** | +| rocminfo after HIP test | **Hangs forever** | **Works normally** | +| Multiple sequential HIP programs | **Only 1st works, GPU dead after** | **All work** | +| SDMA fence at boot | Warning (cosmetic) | Same (separate issue) | +| Sustained HIP compute | **Crashes via KIQ/TLB** | **Stable via MMIO** | +| Vulkan performance | Unaffected | Unaffected | + +### 20.8 Status + +**REBOOT REQUIRED** to load the patched module. + +Post-reboot validation: `./post_reboot_test.sh` + +--- + +## 21.

Overview + +ComfyUI is a node-based Stable Diffusion GUI that runs Z-Image Turbo (a Lumina2-architecture model) via PyTorch with ROCm/HIP on the AMD BC-250 GPU. The model uses a GGUF-quantized diffusion model (Q5_K_S) loaded via the ComfyUI-GGUF custom node, with a Gemma 2 2B text encoder and a Flux-compatible VAE. + +### What's Running + +| Component | File | Size | Format | +|-----------|------|------|--------| +| Diffusion Model | `z_image_turbo-Q5_K_S.gguf` | 5.2 GB | GGUF Q5_K_S | +| Text Encoder | `gemma2_2b_lumina2.safetensors` | 9.8 GB | Safetensors (f32) | +| VAE | `ae.safetensors` | 335 MB | Safetensors (f32) | + +### Pipeline + +``` +[ComfyUI WebUI :8188] → [PyTorch] → [ROCm/HIP] → [AMD BC-250 GPU] + ↓ +[Gemma 2 2B Text Encoder] → CLIP Encode → [Z-Image Turbo Diffusion] → [VAE Decode] → Image +``` + +--- + +## 2. Architecture + +### Z-Image Turbo Details + +- **Architecture**: Lumina2 (Lumina-Image 2.0 family) +- **Base**: Z-Image by Freepik, turbo-distilled variant +- **Text Encoder**: Gemma 2 2B (Google, 2304-dim embeddings) +- **VAE**: Flux-compatible autoencoder (`ae.safetensors`) +- **Sampler**: Euler with SGM Uniform scheduler, 8 steps (turbo) +- **CFG Scale**: 3.0 (turbo models use low CFG) +- **Latent Format**: Flux-style latent space + +### Why GGUF? + +The BC-250 has ~14.7 GB shared system RAM. The full FP16 diffusion model would be too large. GGUF Q5_K_S quantization reduces the model from ~12+ GB to 5.2 GB, making it feasible alongside the text encoder and VAE. + +--- + +## 3.

Model loading was solved by bypassing the GPU entirely (CPU-side memset/memcpy on host-mapped memory). However, **actual GPU compute kernels** (inference) also trigger KIQ/TLB operations and crash identically. **Next step**: Try Vulkan backend (radv driver) which uses a different GPU command path that does NOT go through KFD/KIQ. + +--- + +## 2.

Known Issues & Workarounds + +### Issue 1: KIQ Fence Timeout After Process Exit + +**Symptom**: `amdgpu: timeout waiting for kiq fence` in kernel log. +**Cause**: KFD queue cleanup on the BC-250's KIQ ring hangs. +**Impact**: GPU unusable until reboot (system stays up with `gpu_recovery=1`). +**Workaround**: Use long-running daemon processes. Don't frequently start/stop HIP programs. + +### Issue 2: Only One HIP Session Per Boot + +**Symptom**: Second HIP process hangs at `hipGetDeviceCount()`. +**Cause**: First process exit corrupts KIQ state; GPU doesn't fully recover. +**Workaround**: Design workloads as single long-running process. Reboot between sessions. + +### Issue 3: hpd IRQ Errors at Boot + +**Symptom**: `[drm] *ERROR* Failed to clear hpd(rx) source=X on init` +**Cause**: Display hotplug IRQ on headless system (no monitor connected). +**Impact**: Cosmetic only, no functional effect. +**Fix**: `amdgpu.dc=0` in kernel parameters disables display controller. + +### Issue 4: rocm-smi Crashes GPU + +**Symptom**: Running `rocm-smi --showhw` causes KIQ timeout. +**Cause**: SMI queries trigger GPU management commands through KIQ. +**Workaround**: **Never run `rocm-smi`** on this GPU. Use `rocminfo` for device info instead. + +### Issue 5: Compute Units Reported as 12 (not 24) + +**Symptom**: `hipGetDeviceProperties` reports 12 CUs. +**Cause**: HIP reports shader engines × CU arrays = 12. Real hardware has 24 CUs (4 arrays × 2 SIMDs × ~3 CUs). KFD topology shows `cu_per_simd_array=10`, `simd_arrays_per_engine=2`, `array_count=4`. +**Impact**: None — actual compute throughput matches the 24 CU hardware. + +--- + +## 8.

When the code calls `cudaMemset` or `cudaMemcpy` on this memory, the GPU processes it through its command queue → KIQ ring. But since the memory IS host memory, plain `memset()`/`memcpy()` from the CPU works identically — without touching the GPU at all. This completely removes all GPU involvement during the model loading phase (tens of thousands of tensor operations), while GPU compute kernels still run on the GPU for actual inference. + +### Previous Root Cause Chain (Process Exit) + +``` +HIP process exits + → KFD driver runs kfd_process_destroy_wq (async worker) + → Unmaps compute queues from GPU + → Sends unmap command through KIQ ring + → KIQ ring on BC-250 hangs (hardware/firmware bug) + → "timeout waiting for kiq fence" + → Without gpu_recovery=1: system freeze (shared RAM corruption) + → With gpu_recovery=1: GPU unusable, system survives +``` + +### Crash #11: Inference (GPU Compute Kernels) + +**Status: UNSOLVED — this is the current blocker.** + +Strategy C fully solved model loading (zero KIQ), but the first actual **GPU compute operation** (inference/image generation) triggers the same KIQ/TLB crash. + +#### Crash #11 Timeline + +``` +05:50:26 Model loaded successfully (Z-Image architecture, ~7.6 GB) +05:50:26 GPU status: ZERO KIQ timeouts, fully stable +05:54:46 WebSocket client connected (user opened Web UI) +05:55:18 Job queued: txt2img | prompt="blonde woman" | 512x1024 | steps=8 +05:55:18 [SDWrapper] Calling generate_image()... ← LAST APP LOG +05:55:33 KERNEL: "timeout waiting for kiq fence" (15s after generate) +05:55:33 KERNEL: "TLB flush failed for PASID 32770" +05:55:46 KERNEL: "timeout waiting for kiq fence" (second timeout) +05:55:46 System crash → hard reboot +``` + +#### Analysis + +- Model loading is 100% stable with Strategy C (CPU-side memset/memcpy) +- But `generate_image()` invokes actual **HIP compute kernels** on the GPU +- These kernels trigger TLB flushes via the KIQ ring — same failure mode +- The 15-second gap (05:55:18 → 05:55:33) matches the KIQ timeout threshold +- This proves that **any non-trivial GPU compute** triggers the KIQ bug + +#### Root Cause Chain (Inference) + +``` +generate_image() called + → GGML builds computation graph (matmul, attention, conv2d, etc.) + → ggml_backend_cuda_graph_compute() dispatches HIP kernels + → First kernel launch requires GPU page table setup for compute buffers + → GPU issues TLB flush via KIQ ring + → KIQ ring hangs on BC-250 (same hardware bug as model loading) + → "TLB flush failed for PASID 32770" + → "timeout waiting for kiq fence" + → System crash (shared RAM, no safe GPU reset) +``` + +#### Key Difference from Model Loading + +| Phase | Operations | Strategy C Fix | GPU Involvement | +|-------|-----------|---------------|-----------------| +| Model Load | memset, memcpy (tensor init/copy) | Replaced with CPU ops | **None** (bypassed) | +| Inference | matmul, conv2d, softmax, attention | Cannot replace with CPU | **Required** (actual compute) | + +Strategy C works for loading because memset/memcpy are "dumb" operations that don't need GPU. But inference requires actual GPU matrix multiplications — these CANNOT be replaced with CPU equivalents while staying on the HIP backend. + +#### Next Steps: ROCm Inference Strategy Cascade + +The goal is to get ROCm/HIP inference working on BC-250, no matter what it takes. The strategies below are ordered by investigation priority. + +| # | Strategy | Approach | Effort | Rationale | +|---|----------|----------|--------|----------| +| D | **Pre-fault all pages before compute** | Use `hipMemPrefetchAsync` or `mlock`/`madvise` to force all page table entries into the GPU TLB before any kernel launches | Medium | If all pages are already mapped, the GPU should NOT need TLB flushes during compute. The KIQ hang may only happen on cold TLB misses. | +| E | **Minimal compute test** | Run a tiny HIP kernel (e.g. 1 element, single thread) on host-mapped memory after model load | Low | Determines if ALL GPU compute crashes or only large/sustained workloads. If tiny kernels survive, we can progressively increase size to find the threshold. | +| F | **Alternative TLB invalidation** | Set `amdgpu.noretry=1` (changes page fault to immediate kill instead of retry/flush) and try `HSA_OVERRIDE_GFX_VERSION=10.1.0` with xnack variants | Low | Different noretry/xnack combos may change how the GPU handles TLB misses — possibly avoiding KIQ entirely. | +| G | **Increase KIQ timeout** | Patch `amdgpu` module or use debugfs to increase KIQ fence timeout beyond 15s | Medium | The operation may NOT be hanging forever — it may just be slow. If the timeout is 60s+ the flush might complete. Current `lockup_timeout=120000` only affects general lockup, not KIQ specifically. | +| H | **Kernel driver source patch** | Modify `amdgpu_gmc_flush_gpu_tlb_pasid()` in the kernel to use MMIO-based TLB invalidation instead of KIQ for gfx1013 | High | RDNA1/gfx10 supports MMIO register-based TLB invalidation as a fallback. Bypasses KIQ ring entirely. Requires building a custom kernel module. | +| I | **Graph-level CPU fallback** | Intercept `ggml_backend_cuda_graph_compute()` to run compute graphs on CPU backend when on BC-250 while keeping tensors in host-mapped GPU memory | High | Model stays loaded via ROCm/HIP (working), but compute is done by CPU. ROCm is still running the show — just delegating the math. | +| J | **hipGraph / stream serialization** | Use `hipGraphLaunch` or extreme stream serialization (`HIP_LAUNCH_BLOCKING=1` + single-op batches) to minimize concurrent TLB pressure | Medium | Multiple concurrent kernel launches may overwhelm the KIQ ring. Forcing single-kernel-at-a-time execution may let each TLB flush complete before the next. | + +**Recommended execution order: E → D → F → G → H → J → I** + +Strategy E (minimal compute test) should be done first — it takes 5 minutes and tells us whether the problem is ALL GPU compute or only sustained/large workloads. This fundamentally determines which subsequent strategies are viable. + +--- + +## 13. Recommendations for Production Use + +### Architecture + +1. **Run a single long-lived daemon** for GPU workloads (e.g., stable-diffusion.cpp server) +2. **Never restart the daemon frequently** — each restart risks KIQ timeout +3. **Use systemd service** with `Restart=no` (manual restart only, with reboot if needed) +4. **Monitor via HTTP API**, not GPU tools — `rocm-smi` and `clinfo` can destabilize GPU + +### Required Source Code Patches (ggml-cuda.cu) + +The GGML HIP backend requires two patches for BC-250 compatibility: + +#### Patch 1: hipHostMalloc Allocation (ggml_cuda_device_malloc) +Replace `hipMalloc`/`hipMallocManaged` with `hipHostMalloc(Mapped|Coherent)` when `GGML_HIP_HOST_ALLOC=1`.

The KIQ issue only manifests during process exit (KFD cleanup) or sustained compute with many TLB flushes. +3. **MMIO path exists and is well-tested**: It's the fallback path used during early init and in SR-IOV environments. It's not untested code. +4. **Minimal risk**: The change only affects gfx1013 (Cyan Skillfish / BC-250). No other GPU is affected. + +--- + +## 16. Enterprise Assessment: Do We Need to Downgrade the Kernel? + +### Answer: NO — A Targeted Kernel Module Patch is Superior + +| Approach | Pros | Cons | Recommended | +|----------|------|------|-------------| +| **Kernel 5.10.0** (community suggestion) | Known working for mining | Ancient kernel, no modern features, breaks ROCm 7.2 compatibility, security nightmares, incompatible with CachyOS | **NO** | +| **LTS Kernel 6.12.68** (already installed) | Quick test, may have fewer KIQ issues | Still has same gmc_v10_0.c code path, unlikely to solve root cause | **TRY FIRST** (low effort) | +| **Current 6.18.8 + amdgpu module patch** | Fixes root cause directly, keeps modern kernel, minimal risk | Requires building custom kernel module | **YES — Primary strategy** | +| **Current 6.18.8 + Vulkan backend** | Already proven working (37-150s/image) | Slower than HIP, no PyTorch/ML framework support | **YES — Parallel fallback** | + +### Why Kernel 5.10 is NOT the Answer + +1. **ROCm 7.2 requires glibc ≥2.34**: Kernel 5.10 era distros have older glibc +2. **CachyOS cannot run 5.10**: Completely incompatible package ecosystem +3. **Security**: 5.10 is EOL for most purposes, massive vulnerability surface +4. **The root cause is code-level**: The KIQ-forced TLB flush exists in the amdgpu module, which is the same code in 5.10 but may behave differently due to simpler KIQ implementation in that era +5. **The mining OS uses AMDGPU-PRO** (proprietary): That's a completely different driver stack, not the in-tree amdgpu + +### Why the Module Patch is the Right Approach + +The open-source amdgpu module already contains the MMIO fallback path.

Action Plan — Phased Approach + +### Phase 0: Quick Test — LTS Kernel Boot (15 minutes) +**Rationale**: The 6.12.68 LTS kernel may have a subtly different amdgpu module. Worth testing before investing in a custom module build. + +```bash +# 1. Add LTS kernel boot entry to Limine +# 2. Reboot into 6.12.68-2-cachyos-lts +# 3. Run hip_vector_add +# 4. Run sustained compute test (larger workload) +# 5. Check KIQ timeouts +``` + +**Decision gate**: If LTS kernel eliminates KIQ timeouts → use it. If not → proceed to Phase 1. + +### Phase 1: Custom amdgpu Kernel Module (2-4 hours) +**Rationale**: The definitive fix. Forces MMIO TLB invalidation for gfx1013. + +```bash +# 1. Get kernel source for current kernel +pacman -S linux-cachyos-headers asp +asp export linux-cachyos # or download kernel source matching 6.18.8 + +# 2. Extract just the amdgpu module source + +# 3. Apply patch to gmc_v10_0.c: +# - Force MMIO path for IP_VERSION(10, 1, 3) +# - Set flush_pasid_uses_kiq = false for gfx1013 + +# 4. Build only the amdgpu.ko module (not full kernel) + +# 5. Install as override: +sudo cp amdgpu.ko.zst /lib/modules/$(uname -r)/updates/amdgpu.ko.zst +sudo depmod -a + +# 6. Reboot and test +``` + +### Phase 2: Sustained Compute Validation (1-2 hours) +After Phase 1 module is loaded: + +```bash +# 1. Run hip_vector_add — baseline +# 2. Run progressively larger workloads (matmul, attention, conv2d) +# 3. Run multiple iterations without reboot +# 4. Load sd.cpp model via HIP backend (CPU-side ops, Strategy C) +# 5. Attempt inference (the operation that crashed in Crash #11) +# 6. Monitor for KIQ timeouts throughout +``` + +### Phase 3: Full Stack Validation (2-4 hours) +If Phase 2 passes — see [ZImage_Documentation.md](ZImage_Documentation.md) for Z-Image setup: + +```bash +# 1. Start Z-Image server (bash ~/start-zimage.sh) +# 2. Load model via API (see ZImage_Documentation.md Section 6) +# 3. Generate images at 512×512, 512×1024, 1024×1024 +# 4. Compare performance vs Vulkan backend (~79s reference) +# 5. Stress test: 10+ consecutive generations +# 6. Kill and restart server (test KIQ on process exit) +``` + +### Phase 4: PyTorch / ML Framework (4-8 hours, if needed) +Only if PyTorch/ML is needed beyond sd.cpp: + +```bash +# 1. Build PyTorch from source with PYTORCH_ROCM_ARCH=gfx1010 +# 2. Build rocBLAS, hipBLAS from source (should work on ROCm 7.2) +# 3. Test basic tensor operations +# 4.

BC-250's KIQ implementation has a hardware/firmware bug that causes fence timeouts on these operations. | +| **MMIO path** | The same function has a fallback path using direct MMIO register writes (`WREG32_RLC_NO_KIQ`/`RREG32_RLC_NO_KIQ`). This path is slower but 100% reliable on BC-250. Vulkan (RADV/Mesa) uses this same hardware path and works flawlessly. | +| **gfx1013 scope** | The `IP_VERSION(10, 1, 3)` check ensures ONLY BC-250/Cyan Skillfish is affected. All other GPUs continue using the fast KIQ path. | +| **PASID flush** | The `flush_pasid_uses_kiq` flag controls a separate code path in `gmc_v10_0_flush_gpu_tlb_pasid()`. Disabling it makes PASID-based TLB flushes also avoid KIQ, preventing crashes during KFD (compute) process cleanup. | + +### 20.4 Build Process + +``` +Source: linux-6.18.8 (kernel.org vanilla) +Config: Copied from running CachyOS kernel (/proc/config.gz) +Localver: -3-cachyos (matched via localversion.10-pkgrel + localversion.20-pkgname) +Symvers: Copied from /usr/lib/modules/6.18.8-3-cachyos/build/Module.symvers +Build cmd: make -j12 M=drivers/gpu/drm/amd/amdgpu modules +Vermagic: 6.18.8-3-cachyos SMP preempt mod_unload (MATCHES running kernel) +Signing: Not signed (CONFIG_MODULE_SIG_FORCE=n, LOCK_DOWN_FORCE=NONE) +MODVERSIONS: Disabled (no CRC mismatch risk) +``` + +### 20.5 Installation + +| Step | Command | Result | +|------|---------|--------| +| Backup | `cp amdgpu.ko.zst amdgpu.ko.zst.original` | 5.0M backup created | +| Strip | `strip --strip-debug amdgpu.ko` | 621M → 28M | +| Compress | `zstd -19 amdgpu.ko` | 28M → 4.3M | +| Install | `cp amdgpu.ko.zst /usr/lib/modules/.../amdgpu/` | Replaced | +| Depmod | `depmod -a` | Module deps updated | +| Restore | `/home/dars/kernel-build/restore_original_module.sh` | Available | + +### 20.6 Files Created + +| File | Purpose | +|------|---------| +| `/home/dars/kernel-build/linux-6.18.8/` | Full kernel source tree with patch | +| `/home/dars/kernel-build/bc250-kiq-fix.patch` | Unified diff of the patch | +| `/home/dars/kernel-build/restore_original_module.sh` | Restores original module | +| `/home/dars/VibeROCm/post_reboot_test.sh` | 8-test validation suite | +| `/usr/lib/modules/.../amdgpu.ko.zst.original` | Backup of stock module | + +### 20.7 Expected Results After Reboot + +| Symptom | Before Patch | Expected After | +|---------|-------------|----------------| +| KIQ fence timeout after HIP process exit | **5+ timeouts, GPU dies** | **Zero timeouts** | +| rocminfo after HIP test | **Hangs forever** | **Works normally** | +| Multiple sequential HIP programs | **Only 1st works, GPU dead after** | **All work** | +| SDMA fence at boot | Warning (cosmetic) | Same (separate issue) | +| Sustained HIP compute | **Crashes via KIQ/TLB** | **Stable via MMIO** | +| Vulkan performance | Unaffected | Unaffected | + +### 20.8 Status + +**REBOOT REQUIRED** to load the patched module. + +Post-reboot validation: `./post_reboot_test.sh` + +--- + +## 21.

Subsequent runs improve to ~85s (2nd) → ~82s (3rd+) as GPU caches warm up. + +3. **GGML_CUDA_ENABLE_UNIFIED_MEMORY=1 hurts**: `hipMallocManaged` causes page fault overhead → +18% slower sampling, +88% slower VAE. + +4. **GGML_HIP_HOST_ALLOC=1 worst**: Zero-copy over PCIe is terrible → +27% slower sampling, +114% slower VAE. + +5. **conv_direct is broken**: Setting `vae_conv_direct=true` and/or `diffusion_conv_direct=true` causes the model load to hang indefinitely (13+ minutes, never completes). These bypass rocBLAS im2col+GEMM path for direct convolutions, but the compute graph build is too expensive for this model size (244 VAE f32 tensors + 180 diffusion q5_K tensors). + +6. **ROCm vs Vulkan gap**: ROCm (82–92s) vs Vulkan (79s). ROCm warm runs are very close to Vulkan (~82s vs ~79s, only ~4% gap). The remaining overhead is ggml compute graph scheduling, not GPU compute itself (~10s actual GPU time vs ~67s framework overhead in sampling). + +### Timing Breakdown + +The 92s total breaks down as: + +``` +Text-Encoding (CLIP on CPU): 0.5s ( 0.5%) — NOT a bottleneck +Sampling (8 steps diffusion): 77.4s ( 84.1%) — main bottleneck + ├── Actual GPU compute: ~10s ( 10.9%) + └── ggml framework overhead: ~67s ( 73.2%) — graph scheduling, kernel launches +VAE Decode: 13.9s ( 15.1%) +``` + +The 67s ggml overhead is an upstream limitation of the stable-diffusion.cpp framework, not something fixable via configuration. + +--- + +## 9.

Hardware Overview + +``` +GPU: AMD BC-250 (Cyan Skillfish) +Device ID: 0x13FE (Vendor: 0x1002 AMD) +Architecture: RDNA 1.5 (GFX 10.1.3 / gfx1013) +ROCm Target: gfx10-1-generic (auto-mapped), runs as gfx1010 via override +Compute Units: 24 (reported by some tools as 12 due to SIMD config) +Wavefront Size: 32 (RDNA-style) +Memory: ~14.75 GB shared system GDDR6 (NO dedicated VRAM) +Memory Type: APU-style unified memory (system RAM shared with CPU) +PCIe: Internal SoC fabric (Completion Timeout: Not Supported) +``` + +### Why This GPU Is Special + +The BC-250 is a **cryptocurrency mining board repurposed as a compute accelerator**. It behaves +like an APU — there is **no dedicated VRAM**; all GPU memory operations use system RAM. This has +critical implications: + +| Behavior | Explanation | +|----------|-------------| +| **No standard hipMalloc** | Standard device memory allocation targets non-existent VRAM | +| **hipMallocManaged required** | Unified memory works on shared RAM | +| **hipHostMalloc works** | Pinned host memory is safe for APU | +| **GPU reset = system crash** | Resetting the GPU corrupts shared system RAM | +| **SDMA engine unreliable** | Must disable via `HSA_ENABLE_SDMA=0` | +| **GFXOFF is fatal** | GPU enters power-save and can't wake — CPU hangs on MMIO read | +| **KIQ ring is broken** | KIQ commands cause fence timeouts → system hang | + +--- + +## 2. Prerequisites + +- CachyOS (or Arch-based distro) with a working internet connection +- `sudo` access for the installation user +- `paru` or another AUR helper (for the GPU governor) +- Sufficient disk space (~2 GB for kernel source + build artifacts) + +Install base build dependencies: + +```fish +sudo pacman -S --needed --noconfirm base-devel bc python +``` + +--- + +## 3. Step 1 — Install ROCm Packages + +Install all 16 required ROCm 7.2.0 packages: + +```fish +sudo pacman -S --needed --noconfirm \ + rocm-core hsa-rocr rocminfo rocm-smi-lib rocm-device-libs \ + rocm-llvm comgr hip-runtime-amd rocm-hip-runtime \ + rocm-opencl-runtime rocblas hipblas rocrand rocm-cmake \ + rocm-language-runtime hipblas-common +``` + +You can also run the provided script: +```fish +bash scripts/01_install_rocm_packages.sh +``` + +### Package List + +| Package | Description | +|---------|-------------| +| `rocm-core` | ROCm core (version files) | +| `hsa-rocr` | HSA Runtime API | +| `rocminfo` | ROCm system info tool | +| `rocm-smi-lib` | ROCm SMI library | +| `rocm-device-libs` | ROCm device libraries | +| `rocm-llvm` | ROCm LLVM/Clang compiler (~4.5 GB) | +| `comgr` | AMDGPU Code Object Manager | +| `hip-runtime-amd` | HIP Runtime (AMD backend) | +| `rocm-hip-runtime` | Meta-package for HIP runtime | +| `rocm-opencl-runtime` | ROCm OpenCL runtime | +| `rocblas` | ROCm BLAS library | +| `hipblas` | ROCm BLAS marshalling library | +| `hipblas-common` | hipBLAS common files | +| `rocrand` | ROCm random number generator | +| `rocm-cmake` | ROCm CMake modules | +| `rocm-language-runtime` | ROCm language runtime meta | + +--- + +## 4.

Step 3 — Environment Variables + +The BC-250 requires specific environment variables for ROCm to function. With the v3 kernel +patches (Step 6), only a **minimal set** is needed. + +### For fish shell + +Add to `~/.config/fish/config.fish`: + +```fish +# === ROCm Configuration for AMD BC-250 === +set -gx PATH /opt/rocm/bin $PATH +set -gx LD_LIBRARY_PATH /opt/rocm/lib $LD_LIBRARY_PATH +set -gx ROCM_PATH /opt/rocm +set -gx HSA_OVERRIDE_GFX_VERSION 10.1.0 +set -gx HIP_VISIBLE_DEVICES 0 +set -gx HSA_ENABLE_SDMA 0 +set -gx HSA_TOOLS_LIB "" +set -gx HSA_TOOLS_REPORT_LOAD_FAILURE 0 +``` + +### For bash shell + +Add to `~/.bashrc`: + +```bash +# === ROCm Configuration for AMD BC-250 === +export PATH="/opt/rocm/bin:$PATH" +export LD_LIBRARY_PATH="/opt/rocm/lib:$LD_LIBRARY_PATH" +export ROCM_PATH=/opt/rocm +export HSA_OVERRIDE_GFX_VERSION=10.1.0 +export HIP_VISIBLE_DEVICES=0 +export HSA_ENABLE_SDMA=0 +export HSA_TOOLS_LIB="" +export HSA_TOOLS_REPORT_LOAD_FAILURE=0 +``` + +You can also run the provided script: +```fish +bash scripts/02_configure_environment.sh +``` + +### Variable Reference + +| Variable | Value | Why Required | +|----------|-------|--------------| +| `HSA_OVERRIDE_GFX_VERSION` | `10.1.0` | Maps gfx1013 → gfx1010 (closest supported target) | +| `HIP_VISIBLE_DEVICES` | `0` | Explicit GPU device selection | +| `HSA_ENABLE_SDMA` | `0` | SDMA engine is broken on gfx1013, use shader DMA | +| `HSA_TOOLS_LIB` | `""` | Prevent profiling tools from destabilizing GPU | +| `HSA_TOOLS_REPORT_LOAD_FAILURE` | `0` | Suppress tool load warnings | + +### Variables You Must NOT Set + +These were pre-v3 workarounds that **severely hurt performance**: + +| Variable | Why It's Harmful | +|----------|------------------| +| `GPU_MAX_HW_QUEUES=1` | Serializes all GPU ops to 1 queue — severe slowdown | +| `HIP_LAUNCH_BLOCKING=1` | Forces synchronous kernel launches — prevents pipelining | +| `HSA_DISABLE_FRAGMENT_ALLOCATOR=1` | Not needed with v3 patches | + +--- + +## 6. Step 4 — Kernel Boot Parameters + +### Limine Bootloader + +Edit `/etc/default/limine` and add these parameters to the `KERNEL_CMDLINE`: + +``` +amdgpu.gpu_recovery=1 amdgpu.noretry=0 amdgpu.dc=0 amdgpu.lockup_timeout=120000 amdgpu.ppfeaturemask=0xfff73ef7 +``` + +Apply changes: +```fish +sudo limine-update +``` + +### GRUB Bootloader (if applicable) + +Edit `/etc/default/grub` and add to `GRUB_CMDLINE_LINUX_DEFAULT`: + +``` +amdgpu.gpu_recovery=1 amdgpu.noretry=0 amdgpu.dc=0 amdgpu.lockup_timeout=120000 amdgpu.ppfeaturemask=0xfff73ef7 +``` + +Apply changes: +```bash +sudo grub-mkconfig -o /boot/grub/grub.cfg +``` + +### Parameter Reference + +| Parameter | Value | Purpose | +|-----------|-------|---------| +| `amdgpu.gpu_recovery=1` | Enabled | **CRITICAL**: Auto-recover from GPU hangs | +| `amdgpu.noretry=0` | Retry enabled | Allow page fault retry (required for shared memory) | +| `amdgpu.dc=0` | Display disabled | Disable display controller (headless — prevents IRQ errors) | +| `amdgpu.lockup_timeout=120000` | 120 seconds | Time before declaring GPU hung (allows heavy compute) | +| `amdgpu.ppfeaturemask=0xfff73ef7` | Custom mask | Disable GFXOFF + DeepSleep + ULV (see below) | + +### ppfeaturemask Calculation + +``` +Default value: 0xfff7bfff +BC-250 value: 0xfff73ef7 + +Bits disabled: + Bit 15 (0x8000) — PP_GFXOFF_MASK: GPU enters unrecoverable power-save + Bit 8 (0x0100) — PP_ULV_MASK: Ultra-low voltage may destabilize GPU + Bit 3 (0x0008) — PP_SCLK_DEEP_SLEEP_MASK: Deep clock sleep prevents GPU wake +``` + +--- + +## 7. Step 5 — Modprobe Configuration + +Copy the provided config file: +```fish +sudo cp config/amdgpu.conf /etc/modprobe.d/amdgpu.conf +``` + +Or create manually — file `/etc/modprobe.d/amdgpu.conf`: + +``` +# AMD BC-250 (Cyan Skillfish / gfx1013) — ROCm Stability Parameters +# noretry=0 — Allow page fault retry (critical for shared memory / APU) +# gpu_recovery=1 — Enable GPU recovery on timeout +# sched_hw_submission=2 — Limit concurrent HW submissions (prevent queue overload) +# ppfeaturemask=0xfff73ef7 — Disable GFXOFF (bit 15), DeepSleep (bit 3), ULV (bit 8) +options amdgpu noretry=0 gpu_recovery=1 sched_hw_submission=2 ppfeaturemask=0xfff73ef7 +``` + +--- + +## 8. Step 6 — Build Patched amdgpu Kernel Module + +This is the most critical step. The BC-250 has a hardware/firmware bug where the KIQ (Kernel +Interface Queue) ring causes fatal GPU hangs. The v3 patch applies 8 surgical modifications +across 3 kernel source files to bypass KIQ and add dead-GPU detection. + +### Why a Custom Module is Needed + +The stock amdgpu driver routes TLB (Translation Lookaside Buffer) invalidation commands through +the KIQ ring. On the BC-250, this causes: + +1. **KIQ fence timeouts** → GPU becomes unresponsive +2. **GFXOFF power-save** → GPU can't wake, CPU hangs on MMIO read (no PCIe timeout) +3. **System freeze** → No recovery possible, hard power-off required + +The v3 patch has three protection layers: +- **Layer 1**: Disable GFXOFF for Cyan Skillfish (`gfx_v10_0.c`) +- **Layer 2**: KIQ bypass + dead-GPU detection (`gmc_v10_0.c`, `amdgpu_gmc.c`) +- **Layer 3**: Boot parameters disable GFXOFF/DeepSleep/ULV (Step 4) + +### CRITICAL: Use CachyOS Kernel Source (Not Vanilla!) + +**You MUST build from the CachyOS kernel source**, not vanilla kernel.org source. CachyOS patches +their kernel with struct layout changes that are incompatible with vanilla source headers. Building +from vanilla kernel source will produce a module that causes a **NULL pointer dereference** at boot +in `drm_vma_offset_add` during `gmc_v10_0_sw_init`. + +### Build Process + +#### Option A: Automated (Recommended) + +The provided build script handles everything: + +```fish +# Edit scripts/04_build_patched_module.sh and verify your kernel version first! +bash scripts/04_build_patched_module.sh +``` + +#### Option B: Manual Step-by-Step + +##### 1. Identify Your Kernel Version + +```fish +uname -r +# Example output: 6.19.6-2-cachyos +``` + +Note both the **kernel version** (e.g., `6.19.6`) and the **full string** (e.g., `6.19.6-2-cachyos`). + +##### 2. Find the Matching CachyOS Source + +Go to https://github.com/CachyOS/linux/releases and find the release matching your kernel. + +For example, kernel `6.19.6-2-cachyos` → release `cachyos-6.19.6-1` or similar. + +```fish +mkdir -p ~/kernel-build +cd ~/kernel-build + +# Download (replace URL with your matching version) +curl -L -o cachyos-source.tar.gz \ + "https://github.com/CachyOS/linux/archive/refs/tags/YOUR_TAG.tar.gz" + +# Extract +tar xf cachyos-source.tar.gz +cd linux-* # or whatever the extracted directory is named +``` + +##### 3. Prepare Build Environment + +```fish +set KVER (uname -r) + +# Copy the running kernel's config and build files +cp /usr/lib/modules/$KVER/build/.config . +cp /usr/lib/modules/$KVER/build/Module.symvers . + +# Copy localversion files (these set the kernel version string) +cp /usr/lib/modules/$KVER/build/localversion.* . 2>/dev/null + +# Prepare the build system +make LLVM=1 olddefconfig +make LLVM=1 modules_prepare +``` + +> **Note**: `LLVM=1` is **mandatory** — CachyOS kernels are compiled with Clang, not GCC. +> Using GCC will produce an incompatible module. + +##### 4. Apply the Patches + +Copy the three patch scripts from this guide's `patches/` directory to the BC-250, then run them: + +```fish +set AMDGPU_DIR (pwd)/drivers/gpu/drm/amd/amdgpu + +python3 patches/patch1_gfxoff.py $AMDGPU_DIR +python3 patches/patch2_gmc.py $AMDGPU_DIR +python3 patches/patch3_amdgpu_gmc.py $AMDGPU_DIR +``` + +Verify the patches were applied: +```fish +grep -c "BC-250" $AMDGPU_DIR/gfx_v10_0.c # Should be ≥ 4 +grep -c "BC-250" $AMDGPU_DIR/gmc_v10_0.c # Should be ≥ 14 +grep -c "BC-250" $AMDGPU_DIR/amdgpu_gmc.c # Should be ≥ 9 +``` + +##### 5. Build the Module + +```fish +make LLVM=1 -j(nproc) M=drivers/gpu/drm/amd/amdgpu modules +``` + +This takes 3-10 minutes depending on CPU. The output should end with: +``` +LD [M] drivers/gpu/drm/amd/amdgpu/amdgpu.ko +``` + +##### 6. Strip and Compress + +```fish +# Strip debug symbols: ~600MB → ~30MB +strip --strip-debug drivers/gpu/drm/amd/amdgpu/amdgpu.ko + +# Compress: ~30MB → ~4.5MB +zstd -19 -f drivers/gpu/drm/amd/amdgpu/amdgpu.ko +``` + +--- + +## 9. Step 7 — Install Module & Reboot + +##### 1. Backup the Original Module + +```fish +set KVER (uname -r) +set MODULE_DIR /usr/lib/modules/$KVER/kernel/drivers/gpu/drm/amd/amdgpu + +sudo cp $MODULE_DIR/amdgpu.ko.zst $MODULE_DIR/amdgpu.ko.zst.original +``` + +##### 2. Install the Patched Module + +```fish +sudo cp drivers/gpu/drm/amd/amdgpu/amdgpu.ko.zst $MODULE_DIR/amdgpu.ko.zst +sudo depmod -a +``` + +##### 3. Rebuild Initramfs + +For Limine: +```fish +sudo limine-update +``` + +For GRUB/mkinitcpio: +```fish +sudo mkinitcpio -P +``` + +##### 4. Verify Before Reboot + +```fish +# Check the installed module has all 9 BC-250 strings +zstd -d -c $MODULE_DIR/amdgpu.ko.zst | strings | grep "BC-250" +``` + +Expected output (9 strings): +``` +BC-250: GFXOFF disabled to prevent GPU power-state hangs +BC-250: GPU unreachable (MMIO returned 0xFFFFFFFF)... +BC-250: GPU died during sem acquire (0xFFFFFFFF) +BC-250: GPU died during TLB flush ACK wait (0xFFFFFFFF) +BC-250: GPU unreachable in fw_reg_write_reg_wait... +BC-250: GPU died during reg_write_reg_wait (0xFFFFFFFF) +BC-250 KIQ bypass active +BC-250 KIQ bypass active in fw_reg_write_reg_wait +BC-250: MMIO reg write/wait timeout +``` + +##### 5. Reboot + +```fish +sudo reboot +``` + +##### Emergency Rollback + +If the system doesn't boot or the GPU crashes, restore the original module: + +```fish +set KVER (uname -r) +set MODULE_DIR /usr/lib/modules/$KVER/kernel/drivers/gpu/drm/amd/amdgpu + +sudo cp $MODULE_DIR/amdgpu.ko.zst.original $MODULE_DIR/amdgpu.ko.zst +sudo depmod -a +sudo limine-update # or: sudo mkinitcpio -P +sudo reboot +``` + +--- + +## 10. Step 8 — Post-Reboot Verification + +After reboot, run the verification script: + +```fish +bash scripts/06_verify_installation.sh +``` + +Or check manually: + +### Check dmesg for v3 Module + +```fish +sudo dmesg | grep -E "BC-250|GFXOFF|out-of-tree" +``` + +Expected: +``` +amdgpu: loading out-of-tree module taints kernel. +amdgpu 0000:01:00.0: amdgpu: BC-250: GFXOFF disabled to prevent GPU power-state hangs +``` + +### Check for Errors + +```fish +# KIQ timeout errors (should be 0) +sudo dmesg | grep -ci "timeout waiting for kiq fence" + +# GPU unreachable events (should be 0) +sudo dmesg | grep -ci "GPU unreachable\|GPU died" + +# NULL pointer / BUG (should be 0) +sudo dmesg | grep -ci "BUG\|NULL pointer" +``` + +### Check Device Nodes + +```fish +ls /dev/dri/ +# Expected: card0 renderD128 (and by-path/) + +ls /dev/kfd +# Expected: /dev/kfd (character device) +``` + +### Check ppfeaturemask + +```fish +cat /sys/module/amdgpu/parameters/ppfeaturemask +# Expected: 0xfff73ef7 +``` + +### Check rocminfo + +```fish +rocminfo | grep -E "Name:|Marketing|gfx|Done" +``` + +Expected output includes: +``` + Name: gfx1010 + Marketing Name: AMD BC-250 +*** Done *** +``` + +--- + +## 11. Step 9 — HIP Compute Tests + +Compile and run the provided HIP test programs: + +### Compile Tests + +```fish +cd tests/ +hipcc --offload-arch=gfx1010 -o hip_probe hip_probe.cpp +hipcc --offload-arch=gfx1010 -o hip_minimal_test hip_minimal_test.cpp +hipcc --offload-arch=gfx1010 -o hip_vector_add hip_vector_add.cpp +``` + +### Run Tests (in order) + +```fish +# Test 1: Device probe (no compute) +./hip_probe + +# Test 2: Minimal kernel compute (32 values) +./hip_minimal_test + +# Test 3: Full vector add with managed memory (65536 elements, sin²+cos²=1.0) +./hip_vector_add +``` + +### Sequential Stress Test + +The critical test — on unpatched kernels, the **second** consecutive HIP run crashes the system: + +```fish +for i in (seq 1 5) + echo "=== Round $i ===" + ./hip_minimal_test + sleep 2 +end +``` + +All 5 rounds should pass. If any round hangs or crashes, the module patch may not be applied +correctly. + +You can also run the comprehensive test script: + +```fish +bash scripts/07_run_hip_tests.sh +``` + +--- + +## 12. Cyan Skillfish Governor (GPU Clock Management) + +The BC-250's GPU clock/voltage management is handled by the `cyan-skillfish-governor` service. +The kernel patches handle GFXOFF/power-state prevention; the governor handles DPM clock scaling. + +### Installation + +```fish +paru -S cyan-skillfish-governor +``` + +### Enable & Start + +```fish +sudo systemctl enable --now cyan-skillfish-governor +``` + +### Verify + +```fish +systemctl is-active cyan-skillfish-governor +# Expected: active + +cat /sys/class/drm/card0/device/pp_dpm_sclk +# Expected: Shows clock levels with governor managing transitions +``` + +### Safe Operating Points + +| Clock | Voltage | Use Case | +|-------|---------|----------| +| 1000 MHz | 700 mV | Idle | +| 1500 MHz | 900 mV | Light load | +| 2000 MHz | 1000 mV | Compute (max recommended) | + +--- + +## 13. GPU Watchdog (Safety Monitor) + +A safety watchdog script monitors kernel logs for KIQ timeouts and auto-kills GPU processes +before the timeout cascade crashes the system.

Kernel Module Rebuild After Updates + +**Any CachyOS kernel update will replace your patched module.** After updating the kernel, +you must rebuild and reinstall the patched module. + +### Quick Rebuild Steps + +```fish +set OLD_KVER "6.19.6-2-cachyos" # Previous kernel +set NEW_KVER (uname -r) # New kernel after update + +# If kernel version changed, download new CachyOS source and repeat Step 6 +# If only pkgrel changed (e.g., -2-cachyos → -3-cachyos), you may be able to +# just copy the module and rebuild initramfs: + +set MODULE_DIR /usr/lib/modules/$NEW_KVER/kernel/drivers/gpu/drm/amd/amdgpu +sudo cp /usr/lib/modules/$OLD_KVER/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko.zst $MODULE_DIR/ +sudo depmod -a +sudo limine-update +``` + +> **Note**: This copy approach only works if the kernel ABI hasn't changed between versions. +> If the module fails to load, you must do a full rebuild from the new kernel source. + +--- + +## 16. Technical Reference — Why This GPU Needs Patches + +### The KIQ Problem + +KIQ (Kernel Interface Queue) is a privileged ring buffer used by the amdgpu driver for TLB +invalidation and GPU management. On the BC-250, KIQ commands cause **fence timeouts** — the GPU +never acknowledges the command, and the CPU waits indefinitely. + +There are exactly **4 code paths** that use the KIQ ring at runtime: + +| # | Function | File | Patched? | +|---|----------|------|----------| +| 1 | `gmc_v10_0_flush_gpu_tlb()` | gmc_v10_0.c | **YES** — goto use_mmio | +| 2 | `amdgpu_gmc_flush_gpu_tlb_pasid()` | amdgpu_gmc.c | **YES** — direct callout | +| 3 | `amdgpu_gmc_fw_reg_write_reg_wait()` | amdgpu_gmc.c | **YES** — MMIO write+poll | +| 4 | `amdgpu_gfx_enable/disable_kcq()` | amdgpu_gfx.c | No (boot only, works fine) | + +### The GFXOFF Problem + +After a HIP process exits, the GPU enters GFXOFF (a power-saving state).
