Subject: [PATCH 02/22] Add armv8l to list of 32 bit ARM targets

armv8l is what CMAKE_SYSTEM_PROCESSOR is set to when an ARMv8 processor
is in 32-bit mode, so it should be added to the ARMv7 target list even
though it's v8 because it's 32 bits. Currently, it's not in any ARM
target list which means x86 is assumed and the build fails.

+# 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 \

+## 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
