Derivative of Redox OS (https://www.redox-os.org) adding: - AMD GPU driver (amdgpu) via LinuxKPI compat layer - ext4 filesystem support (ext4d scheme daemon) - ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG) - Custom branding (hostname, os-release, boot identity) Build system is full upstream Redox with RBOS overlay in local/. Patches for kernel, base, and relibc are symlinked from local/patches/ and protected from make clean/distclean. Custom recipes live in local/recipes/ with symlinks into the recipes/ search path. Build: make all CONFIG_NAME=redbear-full Sync: ./local/scripts/sync-upstream.sh

# Bare Metal Test Log — AMD Hardware
|
|
|
|
Template for recording test results when booting Redox on AMD hardware.
|
|
Fill one section per test run. Date is ISO 8601.
|
|
|
|
## How to Test
|
|
|
|
```bash
|
|
# 1. Build the image
|
|
./local/scripts/build-amd.sh
|
|
|
|
# 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
|
|

### [DATE] — [HARDWARE MODEL]
|
|
|
|
**Hardware:**
|
|
- Vendor:

|
|
|
|
**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
|

## 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: (pending first test with P0 patches applied)
|
|
- Config: my-amd-desktop
|
|
- Kernel patch: P0-amd-acpi-x2apic.patch (with timeout + SIPI fixes)
|
|
|
|
**Result:** PENDING TEST
|
|
|
|
**Known from HARDWARE.md:**
|
|
- Previous status: **Broken** — crash due to unimplemented ACPI function
|
|
- Reference: jackpot51/acpi#3
|
|
- With P0 patches applied, x2APIC should now work; need to verify the specific
|
|
ACPI function that was missing
|

### 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
|
|
- Likely needs AML opcode support added to `aml_physmem.rs` or `acpi.rs`
|

### 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)
