+# MediaTek MT7925 WiFi 7 / Bluetooth support
+#
+# The MT7925 is a WiFi 7 (802.11be) + Bluetooth combo chip found in many
+# 2024-2025 laptops. It requires specific workarounds for stable operation.
+#
+# Known issues:
+# - Power management causes random disconnections
+# - ASPM (Active State Power Management) causes hangs
+# - CLC (Country Location Code) causes 6GHz band instability
+# - WiFi often fails to reconnect after suspend/resume
+# - wpa_supplicant has issues; iwd is recommended
+#
+# Devices using MT7925:
+# - Razer Blade 14 (RZ09-0530) 2025
+# - ThinkPad P16s Gen 4
+# - Other 2024-2025 laptops with WiFi 7

+# Razer Blade 14 (RZ09-0530)
+
+Model year: 2025
+
+## Hardware Specifications
+
+- **Model:** RZ09-0530
+- **CPU:** AMD Ryzen AI 9 HX 370 (Strix Point)
+- **iGPU:** AMD Radeon 880M / 890M
+- **dGPU:** NVIDIA GeForce RTX 5060 Max-Q (Blackwell)
+- **Display:** 14" 2560x1600 OLED, 240Hz
+
+## Identifying Your Model
+
+```bash
+nix-shell -p dmidecode --run "sudo dmidecode -s system-product-name"
+# Should output: Blade 14 - RZ09-0530
+```
+
+## Usage
+
+```nix
+{
+  imports = [
+    inputs.nixos-hardware.nixosModules.razer-blade-14-RZ09-0530
+  ];
+}
+```
+
+## Features
+
+This profile configures:
+
+- AMD CPU with microcode updates
+- NVIDIA Prime offload (use `nvidia-offload` command for GPU-intensive applications)
+- AMD iGPU for early KMS
+- Power management for hybrid graphics
+- Proper PCI bus IDs for the hybrid GPU setup
+
+## Optional: OpenRazer for RGB Control
+
+If you want to control the Razer RGB keyboard lighting, you can enable OpenRazer:
+
+```nix
+{
+  hardware.openrazer = {
+    enable = true;
+    # Disable keyStatistics if using a keyboard remapper like kanata
+    keyStatistics = false;
+    users = [ "your-username" ];
+  };
+
+  # Optional: Polychromatic GUI for RGB control
+  environment.systemPackages = [ pkgs.polychromatic ];
+}
+```
+
+## Known Issues
+
+- None reported yet
+
+## Additional Notes
+
+- The NVIDIA RTX 5060 Max-Q uses the Blackwell architecture and works with the open kernel modules (`hardware.nvidia.open = true`)
+- Fine-grained power management is enabled by default for better battery life
+- Use `nvidia-offload <command>` to run applications on the discrete GPU
