PoCX v1.0.0-rc.11

What's New

Plotter v2 — GPU-fused ring buffer plotter with CPU fallback

• Ring buffer architecture moves scatter+compress entirely to GPU, reducing host memory from 3+ GiB to 1 GiB
• Variable compression X1–X6 with constant GPU memory via multi-pass XOR-accumulate
• Escalation (-e N): hold N warps per write buffer for better HDD throughput
• Async write (-a): overlap GPU computation with disk I/O
• Multi-path round-robin with buffer-level interleaving across drives
• CPU plotting mode (default) with rayon-parallel hashing, supports all features
• Per-path seed and resume support for interrupted plots
• Published to crates.io as pocx_plotter_v2

Cross-platform plotfile fixes

• Replace shell commands (df, lsblk, diskutil) with statvfs() for sector size detection
• Auto-disable direct I/O on network/virtual filesystems (NFS, SMB, 9p, FUSE)
• fallocate → ftruncate fallback for unsupported filesystems
• Windows: Unicode volume path resolution, UNC/mapped drive support, network drive detection

Broader platform support

• aarch64-unknown-linux-musl release target for embedded ARM64 devices
• x86_64-unknown-linux-musl release target for older glibc systems
• On-demand MIPS32 cross-compilation workflow (Dreambox DM7080 HD / BCM7435)
• Remove secp256k1 C dependency from pocx_address for easier cross-compilation
• Replace stat -c %D shell command with libc::stat syscall in miner

Breaking Changes

• Plotter v2: -w (warps) is now required, fill-disk mode removed
• Plotter v2: -m (memory limit) removed
• Plotter v2: -D (double-buffer) renamed to -a (async-write)
• Plotter v2: --line-progress removed (replaced by callback API)

Platforms:

• Linux x86_64 (glibc and musl builds)
• Linux ARM64 (glibc and musl builds)
• Android ARM64
• Windows x86_64
• macOS x86_64 / ARM64 (Apple Silicon)

Linux Compatibility Note:

• *-linux-musl builds are statically linked and work on any Linux distribution
• Use musl builds for maximum compatibility (Ubuntu 20.04+, Debian, Alpine, etc.)
• *-linux-gnu builds require glibc 2.39+ (Ubuntu 24.04+, Fedora 40+, Arch)

Binaries:

• pocx_miner - Mining client
• pocx_plotter - Plot file generator (GPU accelerated when OpenCL available)
