redbear-power: v1.1 — full Phase A→D implementation
Comprehensive implementation per local/docs/redbear-power-improvement-plan.md.
Source: 2376 LoC across 10 modules (was 1396/6 in v0.6, +980 LoC).
Cross-compile: 2.8 MB stripped Redox ELF binary.
SHA256: 1b6f9db6ce79e77957bbb1fd606c430516015d5f02f3b64cb6f395e2f63b8e04
Modules:
- main.rs (376) — event loop, key + mouse dispatch, render orchestration
- app.rs (421) — App, CpuRow, Governor, ThrottleMode, PackageThermal, HybridInfo
- render.rs (498) — header/table/controls/help/snapshot rendering
- acpi.rs (166) — CPU enumeration, ACPI _PSS, CPUID fallback
- cpuid.rs (350) — CPUID leaf decoding (vendor, family, model, SIMD, cache, hybrid)
- bench.rs (123) — prime-sieve stress benchmark for thermal response testing
- dbus.rs (202) — D-Bus export via zbus 5 (org.redbear.Power, --dbus flag)
- msr.rs (127) — MSR constants + PackageThermal decoder
- cpufreq.rs (50) — governor hint read/write
- theme.rs (72) — central color palette (const Style)
Phase A — bug fixes:
- R1: PROCHOT pulse bug — Instant::now() math always ~0, pulse never toggled.
Replaced with Frame::count() so the bar pulses at a frame-rate-stable rate.
- R5: removed duplicate comment block in snapshot().
- C2: PackageThermal struct + 13 PKG_THERM_* bit constants; full decode of
IA32_PACKAGE_THERM_STATUS (PL1/PL2/CRIT/TT1/TT2/HFI/temp) surfaced in header.
Phase B — quality:
- R3: input poll decoupled from refresh cadence (50ms vs 250-2000ms).
- R4: Rect::centered replaces hand-rolled centered_rect helper.
- R6: area.layout(&Layout) destructuring with compile-time size check.
- O2: theme.rs central color palette (LABEL, BORDER_*, STATUS_*).
- C9: ratatui 0.30 Stylize shorthand across all renders.
Phase C — features:
- C1/C8: cpuid.rs reads leaves 0/1/4/7/0x80000000+/0x1A/0x8000001E.
- C3: SIMD display header line.
- C5: cache hierarchy header line.
- C7: dynamic refresh interval via / key (typed input 50..60000ms + Enter).
- C6: prime-sieve benchmark via b/B keys (one thread per core, AtomicU64
counter, run/stop/status).
Phase D remaining (was deferred per plan s23):
- C4: hybrid CPU detection (CoreType enum, Intel leaf 0x1A, AMD leaf 0x8000001E),
per-CPU row prefixed with type label, Hybrid: 8P + 16E header.
- O1: termion MouseTerminal wrapper enables xterm mouse protocols.
Wheel = scroll, Left-click = select/toggle, Right-click = expand P-state.
hit_test() maps (x, y) to panel rects cached after every render.
- O3: dbus.rs publishes org.redbear.Power on session bus (opt-in via --dbus).
Properties: cpu_count, avg_freq_khz, max_temp_c, avg_load_pct, governor,
throttle_mode, prochot_asserted. Background thread owns the tokio runtime
+ zbus Connection; main thread sends snapshots via mpsc channel. Graceful
degradation if redbear-sessiond is unreachable.
Verification:
- cargo build --release (host): 0 errors, 21 warnings.
- ./redbear-power --once (Linux host, AMD 24-core): renders all features.
- ./redbear-power --dbus (via script(1)): registers on session bus,
emits xterm mouse capture sequences.
- cook redbear-power (Redox target): 2.8 MB stripped binary at
local/recipes/system/redbear-power/target/x86_64-unknown-redox/stage/usr/bin/redbear-power.
ISO rebuild status: blocked by pre-existing upstream nix-0.30.1 vs Redox
relibc SaFlags incompatibility in uutils (recipes/core/uutils). The v1.1
binary IS staged and will be packaged into the next successful ISO build
once that issue is resolved (separate scope).

- local/docs/redbear-power-improvement-plan.md s24 - full status update.

Cross-Reference redbear-power as a Reference Implementation.
Cargo.toml: new dependencies zbus = "5" (tokio feature) and tokio = "1"
(rt + rt-multi-thread + macros) for the D-Bus export.
