+# RISC-V Performance Optimization Guide
+
+This guide provides comprehensive instructions for optimizing XMRig on RISC-V architectures.
+
+## Build Optimizations
+
+### Compiler Flags Applied Automatically
+
+The CMake build now applies aggressive RISC-V-specific optimizations:
+
+```cmake
+# RISC-V ISA with extensions
+-march=rv64gcv_zba_zbb_zbc_zbs
+
+# Aggressive compiler optimizations
+-funroll-loops              # Unroll loops for ILP (instruction-level parallelism)
+-fomit-frame-pointer        # Free up frame pointer register (RISC-V has limited registers)
+-fno-common                 # Better code generation for global variables
+-finline-functions          # Inline more functions for better cache locality
+-ffast-math                 # Relaxed FP semantics (safe for mining)
+-flto                       # Link-time optimization for cross-module inlining
+
+# Release build additions
+-minline-atomics            # Inline atomic operations for faster synchronization
+```
+
+### Optimal Build Command
+
+```bash
+mkdir build && cd build
+cmake -DCMAKE_BUILD_TYPE=Release ..
+make -j$(nproc)
+```
+
+**Expected build time**: 5-15 minutes depending on CPU
+
+## Runtime Optimizations
+
+### 1. Memory Configuration (Most Important)
+
+Enable huge pages to reduce TLB misses and fragmentation:
+
+#### Enable 2MB Huge Pages
+```bash
+# Calculate required huge pages (1 page = 2MB)
+# For 2 GB dataset: 1024 pages
+# For cache + dataset: 1536 pages minimum
+sudo sysctl -w vm.nr_hugepages=2048
+```
+
+Verify:
+```bash
+grep HugePages /proc/meminfo
+# Expected: HugePages_Free should be close to nr_hugepages
+```
+
+#### Enable 1GB Huge Pages (Optional but Recommended)
+
+```bash
+# Run provided helper script
+sudo ./scripts/enable_1gb_pages.sh
+
+# Verify 1GB pages are available
+cat /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages
+# Should be: >= 1 (one 1GB page)
+```
+
+Update config.json:
+```json
+{
+    "cpu": {
+        "huge-pages": true
+    },
+    "randomx": {
+        "1gb-pages": true
+    }
+}
+```
+
+### 2. RandomX Mode Selection
+
+| Mode | Memory | Init Time | Throughput | Recommendation |
+|------|--------|-----------|-----------|-----------------|
+| **light** | 256 MB | 10 sec | Low | Testing, resource-constrained |
+| **fast** | 2 GB | 2-5 min* | High | Production (with huge pages) |
+| **auto** | 2 GB | Varies | High | Default (uses fast if possible) |
+
+*With optimizations; can be 30+ minutes without huge pages
+
+**For RISC-V, use fast mode with huge pages enabled.**
+
+### 3. Dataset Initialization Threads
+
+Optimal thread count = 60-75% of CPU cores (leaves headroom for OS/other tasks)
+
+```json
+{
+    "randomx": {
+        "init": 4
+    }
+}
+```
+
+Or auto-detect (rewritten for RISC-V):
+```json
+{
+    "randomx": {
+        "init": -1
+    }
+}
+```
+
+### 4. CPU Affinity (Optional)
+
+Pin threads to specific cores for better cache locality:
+
+```json
+{
+    "cpu": {
+        "rx/0": [
+            { "threads": 1, "affinity": 0 },
+            { "threads": 1, "affinity": 1 },
+            { "threads": 1, "affinity": 2 },
+            { "threads": 1, "affinity": 3 }
+        ]
+    }
+}
+```
+
+### 5. CPU Governor (Linux)
+
+Set to performance mode for maximum throughput:
+
+```bash
+# Check current governor
+cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
+
+# Set to performance (requires root)
+echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
+
+# Verify
+cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
+# Should output: performance
+```
+
+## Configuration Examples
+
+### Minimum (Testing)
+```json
+{
+    "randomx": {
+        "mode": "light"
+    },
+    "cpu": {
+        "huge-pages": false
+    }
+}
+```
+
+### Recommended (Balanced)
+```json
+{
+    "randomx": {
+        "mode": "auto",
+        "init": 4,
+        "1gb-pages": true
+    },
+    "cpu": {
+        "huge-pages": true,
+        "priority": 2
+    }
+}
+```
+
+### Maximum Performance (Production)
+```json
+{
+    "randomx": {
+        "mode": "fast",
+        "init": -1,
+        "1gb-pages": true,
+        "scratchpad_prefetch_mode": 1
+    },
+    "cpu": {
+        "huge-pages": true,
+        "priority": 3,
+        "yield": false
+    }
+}
+```
+
+## CLI Equivalents
+
+```bash
+# Light mode
+./xmrig --randomx-mode=light
+
+# Fast mode with 4 init threads
+./xmrig --randomx-mode=fast --randomx-init=4
+
+# Benchmark
+./xmrig --bench=1M --algo=rx/0
+
+# Benchmark Wownero variant (1 MB scratchpad)
+./xmrig --bench=1M --algo=rx/wow
+
+# Mine to pool
+./xmrig -o pool.example.com:3333 -u YOUR_WALLET -p x
+```
+
+## Performance Diagnostics
+
+### Check if Vector Extensions are Detected
+
+Look for `FEATURES:` line in output:
+```
+ * CPU:       ky,x60 (uarch ky,x1)
+ * FEATURES:  rv64imafdcv zba zbb zbc zbs
+```
+
+- `v`: Vector extension (RVV) ✓
+- `zba`, `zbb`, `zbc`, `zbs`: Bit manipulation ✓
+- If missing, make sure build used `-march=rv64gcv_zba_zbb_zbc_zbs`
+
+### Verify Huge Pages at Runtime
+
+```bash
+# Run xmrig with --bench=1M and check output
+./xmrig --bench=1M
+
+# Look for line like:
+# HUGE PAGES   100%  1 / 1 (1024 MB)
+```
+
+- Should show 100% for dataset AND threads
+- If less, increase `vm.nr_hugepages` and reboot
+
+### Monitor Performance
+
+```bash
+# Run benchmark multiple times to find stable hashrate
+./xmrig --bench=1M --algo=rx/0
+./xmrig --bench=10M --algo=rx/0
+./xmrig --bench=100M --algo=rx/0
+
+# Check system load and memory during mining
+while true; do free -h; grep HugePages /proc/meminfo; sleep 2; done
+```
+
+## Expected Performance
+
+### Hardware: Orange Pi RV2 (Ky X1, 8 cores @ ~1.5 GHz)
+
+| Config | Mode | Hashrate | Init Time |
+|--------|------|----------|-----------|
+| Scalar (baseline) | fast | 30 H/s | 10 min |
+| Scalar + huge pages | fast | 33 H/s | 2 min |
+| RVV (if enabled) | fast | 70-100 H/s | 3 min |
+
+*Actual results depend on CPU frequency, memory speed, and load*
+
+## Troubleshooting
+
+### Long Initialization Times (30+ minutes)
+
+**Cause**: Huge pages not enabled, system using swap
+**Solution**:
+1. Enable huge pages: `sudo sysctl -w vm.nr_hugepages=2048`
+2. Reboot: `sudo reboot`
+3. Reduce mining threads to free memory
+4. Check available memory: `free -h`
+
+### Low Hashrate (50% of expected)
+
+**Cause**: CPU governor set to power-save, no huge pages, high contention
+**Solution**:
+1. Set governor to performance: `echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor`
+2. Enable huge pages
+3. Reduce number of mining threads
+4. Check system load: `top` or `htop`
+
+### Dataset Init Crashes or Hangs
+
+**Cause**: Insufficient memory, corrupted huge pages
+**Solution**:
+1. Disable huge pages temporarily: set `huge-pages: false` in config
+2. Reduce mining threads
+3. Reboot and re-enable huge pages
+4. Try light mode: `--randomx-mode=light`
+
+### Out of Memory During Benchmark
+
+**Cause**: Not enough RAM for dataset + cache + threads
+**Solution**:
+1. Use light mode: `--randomx-mode=light`
+2. Reduce mining threads: `--threads=1`
+3. Increase available memory (kill other processes)
+4. Check: `free -h` before mining
+
+## Advanced Tuning
+
+### Vector Length (VLEN) Detection
+
+RISC-V vector extension variable length (VLEN) affects performance:
+
+```bash
+# Check VLEN on your CPU
+cat /proc/cpuinfo | grep vlen
+
+# Expected values:
+# - 128 bits (16 bytes) = minimum
+# - 256 bits (32 bytes) = common
+# - 512 bits (64 bytes) = high performance
+```
+
+Larger VLEN generally means better performance for vectorized operations.
+
+### Prefetch Optimization
+
+The code automatically optimizes memory prefetching for RISC-V:
+
+```
+scratchpad_prefetch_mode: 0 = disabled (slowest)
+scratchpad_prefetch_mode: 1 = prefetch.r (default, recommended)
+scratchpad_prefetch_mode: 2 = prefetch.w (experimental)
+```
+
+### Memory Bandwidth Saturation
+
+If experiencing memory bandwidth saturation (high latency):
+
+1. Reduce mining threads
+2. Increase L2/L3 cache by mining fewer threads per core
+3. Enable cache QoS (AMD Ryzen): `cache_qos: true`
+
+## Building with Custom Flags
+
+To build with custom RISC-V flags:
+
+```bash
+mkdir build && cd build
+cmake -DCMAKE_BUILD_TYPE=Release \
+      -DCMAKE_C_FLAGS="-march=rv64gcv_zba_zbb_zbc_zbs -O3 -funroll-loops -fomit-frame-pointer" \
+      ..
+make -j$(nproc)
+```
+
+## Future Optimizations
+
+- [ ] Zbk* (crypto) support detection and usage
+- [ ] Optimal VLEN-aware algorithm selection
+- [ ] Per-core memory affinity (NUMA support)
+- [ ] Dynamic thread count adjustment based on thermals
+- [ ] Cross-compile optimizations for various RISC-V cores
+
