- Replace mutex-protected inputSource with atomic.Pointer for lock-free reads
- Eliminate ~100 mutex operations per second in audio packet hot path
- Add defer pattern for safer mutex unlock in enable/disable functions
- Add error logging for audio write failures
- Consolidate Makefile lint commands for brevity
Remove all subprocess-based audio code to simplify the audio system and
reduce complexity. Audio now uses CGO in-process mode exclusively.
Changes:
- Remove subprocess mode: Deleted Supervisor, IPCSource, embed.go
- Remove audio mode selection from UI (Settings → Audio)
- Remove audio mode from backend config (AudioMode field)
- Remove JSON-RPC handlers: getAudioMode/setAudioMode
- Remove Makefile targets: build_audio_output/input/binaries
- Remove standalone C binaries: jetkvm_audio_{input,output}.c
- Remove IPC protocol implementation: ipc_protocol.{c,h}
- Remove unused IPC functions from audio_common.{c,h}
- Simplify audio.go: startAudio() instead of startAudioSubprocesses()
- Update all function calls and comments to remove subprocess references
- Add constants to cgo_source.go (ipcMaxFrameSize, ipcMsgTypeOpus)
- Keep update_opus_encoder_params() for potential future runtime config
Benefits:
- Simpler codebase: -1,734 lines of code
- Better performance: No IPC overhead on embedded hardware
- Easier maintenance: Single audio implementation
- Smaller binary: No embedded audio subprocess binaries
The audio system now works exclusively via CGO direct C function calls,
with ALSA device selection (HDMI vs USB) still configurable via settings.
Implement SIMD-optimized audio operations using ARM NEON for Cortex-A7 targets
Update Makefile and CI configuration to support NEON compilation flags
Add SIMD implementations for common audio operations including:
- Sample clearing and interleaving
- Volume scaling and format conversion
- Channel manipulation and balance adjustment
- Endianness swapping and prefetching
Add SVG and ICO to cacheable files.
Emit robots.txt directly.
Recognize WOFF2 (font) files as assets (so the get the immutable treatment)
Pre-gzip the entire /static/ directory (not just /static/assets/) and include SVG, ICO, and HTML files
Ensure fonts.css is processed by vite/rollup so that the preload and css reference the same immutable files (which get long-cached with hashes)
Add CircularXXWeb-Black to the preload list as it is used in the hot-path.
Handle system-driven color-scheme changes from dark to light correctly.

Add compiler optimization flags targeting ARM Cortex-A7 with NEON support
to improve performance of audio library builds and Go binaries. The flags
enable vectorization, fast math, and loop unrolling for better execution
speed on the target hardware.
