Bare Metal Validation Log — ACPI and Hardware Evidence

Template for recording bounded bare-metal validation results on AMD and Intel hardware. Fill one section per test run. Date is ISO 8601.

This file is an evidence log, not the canonical source of support language. For current ACPI status and ownership truth, use local/docs/ACPI-IMPROVEMENT-PLAN.md. For hardware-facing support language, use HARDWARE.md.

How to Test

# 1. Build the image
./local/scripts/build-redbear.sh redbear-full

# 2. Burn to USB (DANGEROUS — verify target device!)
./local/scripts/test-baremetal.sh --device /dev/sdX

# 3. Boot from USB on target hardware
# 4. Record results below

Serial Console Setup

For boot debugging, connect a serial console before powering on:

• Baud rate: 115200
• Use a USB-to-TTL serial adapter on the motherboard header
• Or use IPMI/BMC serial-over-LAN if available

Test Run Template

### [DATE] — [HARDWARE MODEL]

**Hardware:**
- Vendor: 
- Model: 
- CPU: (e.g., AMD Ryzen 9 7940HS)
- GPU: (e.g., AMD Radeon 780M integrated)
- Motherboard firmware: UEFI / BIOS
- RAM: (e.g., 32GB DDR5)
- Storage: (e.g., NVMe SSD)

**Build:**
- Redox version: (git rev-parse --short HEAD)
- Config: (e.g., redbear-full)
- Kernel patch version: (checksum of local/patches/kernel/P0-amd-acpi-x2apic.patch)

**Result:** Booting / Broken / Recommended

**Boot log (serial output):**

(paste kernel log here, especially ACPI-related lines)

**Observations:**
- ACPI tables detected: (list any `kernel::acpi` output)
- APIC mode: xAPIC / x2APIC
- CPU count: (how many cores detected)
- Crash location: (if broken, what function/line)
- Display: VESA / GOP / none
- Input: PS/2 keyboard / PS/2 mouse / USB / none
- Network: working / not detected
- Audio: working / not detected

**Issues:**
1. (describe any problems)

Test Results

2026-04-11 — Framework Laptop 16 (AMD Ryzen 7040)

Hardware:

• Vendor: Framework
• Model: Laptop 16 (AMD Ryzen 7040 Series)
• CPU: AMD Ryzen 9 7940HS (13 cores, x2APIC)
• GPU: AMD Radeon 780M (RDNA3, integrated)
• Motherboard firmware: UEFI
• RAM: 32GB DDR5
• Storage: NVMe SSD

Build:

• Redox version: historical note only; fresh rerun needed
• Config: historical pre-rename run; repeat on redbear-full
• Kernel patch: historical P0 ACPI bring-up patch set (with timeout + SIPI fixes)

Result: Booting

Known from current repo docs:

• Previous status: Broken — crash due to unimplemented ACPI function
• Historical boot-baseline ACPI fixes moved this machine out of the Broken path
• Broader bounded validation is still incomplete; a fresh run should replace this carry-forward note

2025-11-09 — Lenovo ThinkCentre M83

Hardware:

• Vendor: Lenovo
• Model: ThinkCentre M83
• CPU: (Intel, x86_64)
• Motherboard firmware: UEFI

Result: Broken

Known issues from HARDWARE.md:

• acpid/src/acpi.rs:256:68: Called Result::unwrap() on an Err value: Aml(NoCurrentOp)
• acpid/src/main.rs:147:39: acpid: failed to daemonize: Error I/O error 5
• Display logs offset past left edge of screen
• [@hwd:40 ERROR] failed to probe with error No such device (os error 19)

Analysis:

• AML interpreter hits unsupported opcode (NoCurrentOp)
• This is in the userspace acpid, not the kernel
• Treat this as an unresolved bare-metal failure record until a fresh validation run disproves it

2024-09-20 — ASUS PRIME B350M-E (Custom Desktop)

Hardware:

• Vendor: ASUS
• Model: PRIME B350M-E (custom)
• CPU: AMD (B350 chipset = Ryzen 1st/2nd gen)
• Motherboard firmware: UEFI

Result: Booting

Known issues from HARDWARE.md:

• Partial PS/2 keyboard support
• PS/2 mouse broken
• No GPU acceleration (VESA/GOP only)

Analysis:

• Boots successfully with xAPIC (Ryzen 1000/2000 uses APIC IDs < 255)
• I2C devices unsupported (touchpad)
• Good candidate for testing P0 patches (verifies no regression on xAPIC systems)
