AMD Platform Driver Scan — Strix Halo (Ryzen AI MAX+ 395)
Scanned 2026-04-20. Box: Bosgame M5 / BeyondMax, Sixunited AXB35 board, BIOS 1.07, NPU fw 1.1.2.65, CachyOS 7.0.0.
The originally linked URL is wrong
drivers.html/chipsets/am5/b650.html is the AM5 desktop chipset page. Strix Halo is a BGA APU (FP8/FP11 socket-class, soldered); it has no discrete chipset driver SKU. The B650 page does not apply.
Correct AMD support roots:

What AMD officially ships for this SKU on Linux
| Component | AMD package | Linux? | Notes |
|---|---|---|---|
| GPU (gfx1151) | amdgpu (mainline) + ROCm 7.x | Yes | Already installed. ROCm Strix Halo guide exists. |
| NPU (XDNA2) | amdxdna (mainline kernel 6.10+) + xrt + xrt-plugin-amdxdna + Ryzen AI SW 1.7.1 | Yes | Installed. SW 1.7.1 (2026-04-08) lists STX + KRK only; Strix Halo (STX-H) not in supported matrix — works in practice, not guaranteed. |
| Chipset driver | 8.02.18.557 (2026-03-09) | Windows only | Bundles PPM/PMF profiles, SMBus, GPIO. No Linux package. Equivalents live in amd_pmf, amd_pstate_epp, k10temp, amd_hsmp kernel drivers — already in CachyOS kernel. |
| Sensor Fusion Hub | amd-sfh-hid (mainline ≥ 5.11) | Yes | Laptop sensors only (accel/gyro/ALS). Strix Halo mini-PC has none wired — driver will bind to nothing, that's fine. |
| Infinity Fabric monitoring | No AMD userland tool | — | Use amd_hsmp + rocm-smi + amd_energy + turbostat. No official package missing. |
| EC / thermals | Vendor BIOS (Bosgame/Sixunited) | — | Not AMD's deliverable. amd_pmf slider covers the AMDI0102 ACPI path. |
What we might be missing — honest list
Nothing from amd.com is installable on Linux that we don't already have. The Windows "Chipset Driver 8.02" maps 1:1 to in-tree kernel drivers we already run. Ryzen AI Software 1.7.1 for Linux is the only other AMD-shipped Linux artefact, and it's redundant with our xrt + amdxdna stack (it bundles the same kernel module + xrt-smi we already have from CachyOS repos).
BIOS / NPU firmware update path
- AMD does not ship BIOS. Strix Halo BIOS comes from the board OEM (Sixunited AXB35 reference → rebadged by Bosgame).
- Canonical update source: strixhalo.wiki Sixunited AXB35 Firmware page (
https://strixhalo.wiki/Hardware/Boards/Sixunited_AXB35/Firmware). All AXB35-based devices share a compatible BIOS family; OEM cross-flashing is community-confirmed but unofficial. - Bosgame's own page:
https://www.bosgamepc.com/pages/bios-download-center. - Linux-native flash path: EFI Shell via
capetron/minisforum-ms-s1-max-biosrecipe (no Windows needed). - NPU firmware (
1.1.2.65) is shipped insidelinux-firmware(amdnpu/*.sbin), not the BIOS. Bumps arrive via distrolinux-firmwareupdates, not AMD.com.
Recommendation
Do not install anything from amd.com. Our existing CachyOS-repo stack (amdgpu, amdxdna, xrt, xrt-plugin-amdxdna, linux-firmware, kernel amd_pmf/amd_hsmp/amd-sfh-hid) is a superset of what AMD publishes for this SKU on Linux. BIOS updates go through the OEM/Sixunited channel on the Strix Halo wiki.
