redbear-power: v1.5 — Motherboard tab (DMI/SMBIOS)
Adds the 4th tab in the multi-view system: Motherboard, reading
SMBIOS/DMI fields from /sys/class/dmi/id/* on Linux hosts.
New module dmi.rs (118 lines):
- DmiInfo struct with 18 Option<String> fields (system, board,
BIOS, chassis, product identity)
- DmiInfo::read() reads each sysfs file independently — one failure
doesn't poison the others
- DmiInfo::available() probes /sys/class/dmi/id/ for Sources header
- DmiInfo::is_empty() drives the panel's empty-state message
- DmiInfo::display(field) helper formats Some→value, None→'?'
Updated app.rs:
- New field dmi: DmiInfo, initialized once in App::new() (no per-tick
refresh — DMI is static)
- TabId::Motherboard variant (4th tab)
- TabId::next() cycles PerCpu → System → Info → Motherboard → PerCpu
Updated render.rs:
- New render_motherboard_panel(app, focused) with 4 section blocks
- render_tab_bar() updated for 4 tabs with hotkey 1/2/3/4 mapping
- Sources header line now includes dmi=ok|no after hwmon=
- render_once now dumps Motherboard panel for headless verification
Updated main.rs:
- mod dmi; declaration
- New dispatch arm TabId::Motherboard => render_motherboard_panel
- Hotkey 4 jumps to Motherboard tab directly
Linux host smoke test (Manjaro, MSI MPG X670E CARBON WIFI):
- Manufacturer: Micro-Star International Co., Ltd.
- Product: MS-7D70
- Board: MPG X670E CARBON WIFI (MS-7D70), Version 1.0
- BIOS: AMI, 1.74, 05/12/2023, Release 5.26
- Chassis: Type 3 (Desktop)
- Serial/UUID correctly report '?' (root-only readable)
Sources header: MSR=ok PSS=no load=ok gov=ok hwmon=ok dmi=ok
Source state: 4117 LoC across 14 modules (v1.4: 3864/13).
Redox stripped: 3.7 MB (SHA256 c44d508c...).
Docs: improvement plan §29, CONSOLE-TO-KDE §3.3.2 v1.5,
RATATUI-APP-PATTERNS §13.17 + §14.
Note: dmi.rs + app.rs changes already landed in aee89315c9 as part
of a qtbase bundled commit; this commit catches up the main.rs
dispatch arm + render.rs panel wiring + all docs that were missing.
