# Task 4 Evidence — Ryzen 7000 / X670E (MS-7D70) Matrix Annotations
**File modified:** `local/docs/HARDWARE-VALIDATION-MATRIX.md`
**Host:** MSI MPG X670E CARBON WIFI (MS-7D70), Ryzen 9 7900X
**Rule applied:** Only honest levels `compile` or `—` were used. No marker claims QEMU-bounded or hardware-validated status for MS-7D70.
## Rows annotated with `[AVAILABLE] (MS-7D70: ...)` markers
1. **AHCI SATA**
`[AVAILABLE] (MS-7D70: AHCI SATA, level: compile)`
(also added refresh-rule note in Notes column)
2. **NVMe**
`[AVAILABLE] (LG Gram: SK Hynix [1c5c:1959]; MS-7D70: NVMe SSD, level: compile)`
3. **PS/2**
`[AVAILABLE] (LG Gram: i8042 keyboard, AUX disabled; MS-7D70: absent, level: —)`
4. **xHCI host controller**
`[AVAILABLE] (LG Gram: 2× xHCI [8086:7ec0, 8086:777d]; MS-7D70: xHCI host controller, level: compile)`
5. **USB storage (BOT)**
`[AVAILABLE] (any USB mass-storage device; MS-7D70: USB storage BOT, level: compile)`
6. **cpufreqd**
`[AVAILABLE] (LG Gram: Arrow Lake-H HWP; MS-7D70: CPU power/CPPC, level: compile)`
7. **thermald**
`[AVAILABLE] (LG Gram: TZ00 + MSR-based; MS-7D70: thermal k10temp [1022:14e3], level: compile)`
8. **x2APIC/SMP**
`[AVAILABLE] (Threadripper 128-thread + LG Gram 16-core hybrid; MS-7D70: MADT/x2APIC CPU enumeration, level: compile)`
## Rows skipped — no matching component row exists in the matrix
- wired Ethernet (RTL8125 10ec:8125) — no `rtl8125` row; existing rows are e1000d/rtl8168d/rtl8139d/ixgbed/virtio-netd
- Wi-Fi (MediaTek MT7922 14c3:0616) — row is `redbear-iwlwifi (Intel Wi-Fi)`
- Bluetooth (0e8d:0616) — no Bluetooth component row
- HDA audio (1022:15e3) — row is `Intel HDA`
- GPU/display (Raphael iGPU 1002:164e) — row is `redox-drm (Intel MTL iGPU)`
- SMBus (1022:790b) — no SMBus component row
- GPIO (AMDIF031) — no GPIO component row
- ACPI shutdown/reboot — no dedicated ACPI component row
- IOMMU/AMD-Vi — no dedicated IOMMU validation row
- TSC calibration — no dedicated TSC calibration row
## Refresh rule note added
In the **AHCI SATA** Notes column (first annotated marker):
> Refresh rule: refresh at every gate: 23 (Gate A), 28 (Wi-Fi), 32 (coexistence), 34 (modeset), 40 (Gate B).
## Grep verification
```bash
$ grep -q 'MS-7D70' local/docs/HARDWARE-VALIDATION-MATRIX.md && echo 'PASS: MS-7D70 found' || echo 'FAIL'
PASS: MS-7D70 found
$ grep -E 'MS-7D70.*level: (compile|—)' local/docs/HARDWARE-VALIDATION-MATRIX.md | wc -l
8
$ grep -E 'MS-7D70.*level: ' local/docs/HARDWARE-VALIDATION-MATRIX.md | grep -vE 'level: (compile|—)' | wc -l
0
```
**Result:** 8 MS-7D70 markers present; all use only `compile` or `—`; 0 markers claim QEMU-bounded or hardware-validated status.
