Red Bear OS — Hardware Validation Matrix
Version: 1.0 (2026-05-20) Target: 4 hardware classes minimum Evidence model: Source-visible → Build-visible → QEMU-validated → Runtime-validated → Hardware-validated
1. Validation Targets
| Class | CPU | Platform | GPU | Priority |
|---|---|---|---|---|
| A1 | AMD Desktop | Ryzen 5000/7000 | Discrete AMD/Intel | P0 |
| A2 | Intel Desktop | Core 12th-14th Gen | Integrated Intel | P0 |
| A3 | AMD Laptop | Ryzen Mobile 5000/7000 | Integrated AMD | P1 |
| A4 | Intel Laptop | Core Mobile 12th-14th Gen | Integrated Intel | P1 |
2. Per-Target Checklist
Boot & Runtime
| Check | Validation Method | Pass Criteria |
|---|---|---|
| Boots to login prompt | Bare metal boot | Login prompt visible within 60s |
| All CPU cores online | dmesg / sys:cpu scheme |
SMP: N CPUs online matches physical core count |
| USB keyboard at boot | Physical test | Keyboard works in bootloader and login |
| USB storage mounts | mount / df |
Mass storage device appears and mounts |
| Wired network DHCP | ifconfig / dhcpd logs |
Obtains IPv4 lease within 10s |
| Temperature readable | redbear-info / coretemp scheme |
Per-core temps displayed |
| Clean shutdown | shutdown -h now |
Powers off without panic |
| Clean reboot | reboot |
Restarts successfully |
Subsystem Validation
| Subsystem | Check | Evidence |
|---|---|---|
| ACPI | Thermal zones readable | /scheme/acpi/thermal/ has entries |
| ACPI | Fan status readable | /scheme/acpi/fan/ has entries (if fans present) |
| C-states | Idle power reduction | Temperature drops 5-10C at idle vs load |
| MSI-X | Network IRQ type | dmesg shows "MSI-X interrupt on CPU N" |
| IOMMU | AMD-Vi initialized | iommu daemon logs "AMD-Vi unit N initialized" |
| Logging | Per-service logs | /var/log/*.log files exist and rotate |
3. Negative-Result Capture
When a target fails, record:
Target: <class>
Component: <subsystem>
Failure: <description>
Evidence: <log excerpt or dmesg>
Bisect: <last known good commit / config>
Workaround: <if any>
4. Current Status
| Target | Status | Last Tested | Blocker |
|---|---|---|---|
| A1 | Not tested | — | No hardware |
| A2 | Not tested | — | No hardware |
| A3 | Not tested | — | No hardware |
| A4 | Not tested | — | No hardware |
QEMU baseline: All checklist items pass in QEMU except temperature (no MSR emulation), IOMMU (QEMU proof only), and USB storage (validated with host-seeded patterns).
5. Test Procedures
Quick Validation (15 minutes)
# On target hardware, boot from live ISO
make live CONFIG_NAME=redbear-full
# Write ISO to USB, boot
# Check CPU cores
cat /scheme/sys/cpu
# Check temperatures
cat /scheme/coretemp/cpu0/temperature
# Check ACPI thermal zones
ls /scheme/acpi/thermal/
# Check network
ping 8.8.8.8
# Check logs
ls /var/log/
Full Validation (1 hour)
# Run all quick checks
# Test USB hotplug (keyboard, storage)
# Test shutdown/reboot cycle
# Capture dmesg to external storage
This matrix is updated as validation evidence is collected. See COMPREHENSIVE-SYSTEM-ASSESSMENT-AND-IMPROVEMENT-PLAN.md for the full improvement plan.
