# 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)
|
|
|
|
```bash
|
|
# 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)
|
|
|
|
```bash
|
|
# Run all quick checks
|
|
# Test USB hotplug (keyboard, storage)
|
|
# Test shutdown/reboot cycle
|
|
# Capture dmesg to external storage
|
|
```
