Changelog

All notable changes to this project will be documented in this file.

[0.1.1] - 2026-07-25

Performance

  • Tick loop skips render/encode/USB send when the active layout's resolved inputs are unchanged (FrameSource::content_fingerprint). Streaming (Xvfb) sources still render every tick.
  • NVIDIA GPU sensors prefer in-process NVML (dedicated worker, hard 500ms recv timeout so a wedged driver cannot pin the tick loop) over forking nvidia-smi every poll; smi remains a fallback with the same budget + kill, and both paths back off when unusable. NVML device_by_index failures demote to smi (not silent empty). (#80, #91)
  • Hybrid AMD+NVIDIA machines register Nvidia before AmdGpu so the discrete GPU owns gpu_* / vram_* keys.
  • SensorHub collision warnings log once per key for the life of the hub (no per-poll journal spam).
  • hwmon skips high-latency JEDEC spd5118 DIMM sensors (~8 ms/poll on typical boards) that no stock layout displays.
  • Adaptive hwmon pruning: after a short discovery window, chips that cannot serve the active layout's needed metrics are skipped (EMA cost > 500µs or simply unneeded).
  • Sensor polling is limited to keys the active layout can display (frontmatter + template token scan against the catalog), with provider short-circuit once those keys are collected.
  • Default sensors.poll_interval_ms lowered from 1000 to 2000 (still one sensor refresh per display frame at the default 2 FPS).
  • list_sensors reports per-key poll cost (cost_us); GUI sensor pickers show live-measured cost so setup can avoid expensive keys.
  • Steady-state daemon footprint on the comparison machine: 0.41% of one core and ~81 MB PSS at default 2 FPS (stock neon-dash, NVML, dirty-frame skip, 2000 ms poll). Earlier post-v0.1.0 remasure was 0.87% / ~72 MB PSS before the 2000 ms poll + layout-needed prune path.

Fixed

  • Clippy -D warnings clean again on CI (type_complexity on the shared sensor catalog, duplicated too_many_arguments allow, plus a couple of follow-on lints).

[0.1.0] - 2026-07-24

Added

  • Initial daemon implementation for controlling Thermalright LCD coolers.
  • Multi-transport device support: raw bulk, SCSI, HID Type 2/3, and LY bulk protocols across nine USB IDs, with automatic discovery and config-overridable VID:PID selection. 87ad:70db (Peerless Vision / GrandVision 360 AIO) is verified on physical hardware; the remaining IDs are implemented against protocol fixtures — testers wanted.
  • Responsive layout rendering at negotiated native resolutions (240x240 through ultrawide), with {# canvas: responsive #} opt-in reflow and uniform containment for fixed-canvas layouts.
  • Support for rendering layout templates using SVG and Tera engine, including built-in layouts.
  • Integrated sensor providers for system temperature, load, power, and memory metrics, with slow/wedged hwmon chip quarantine.
  • D-Bus control command-line interface (CLI) to interface with the running daemon.
  • RAPL udev configuration rule generator to safely allow reading processor power metrics without root.
  • Optional Tauri-based graphical user interface (GUI) for visual configuration and streaming, including overlay color suggestions derived from the selected background image.
  • Support for setting background images on the cooler LCD.
  • Xvfb streaming presets to pipe arbitrary window regions (e.g. conky, cava, btop, nvtop, custom terminal emulators) straight to the cooler.
  • Whole-daemon profiling harness with committed performance baselines (scripts/profile.sh, docs/profiling-baselines.md).

Changed

  • Release tarball installer now uses the bundled daemon binary when present, while source checkouts still build with Cargo.
  • RAPL access now uses a dedicated thermalreader group with 0440 permissions instead of world-readable counters.
  • Xvfb streaming now uses generated Xauthority credentials and private runtime preview frames.

Fixed

  • Stream restarts preserve the original layout tick rate when returning from Xvfb mode.
  • Layout switches now wait for renderer startup confirmation before updating D-Bus state.
  • SVG text variables are XML-escaped before rendering, so labels containing characters like & do not break previews or daemon rendering.
