Fix Clevo keyboard LED mapping for per-key RGB control

[Dronakurl]

This PR fixes the broken per-key RGB control on Clevo ITE 8291 keyboards found in TUXEDO/Clevo laptops.

Problem

The KeyboardLayoutManager returns LED names with a "Key: " prefix (e.g., "Key: W", "Key: F1") but the hardware value lookup in the Clevo controller was using KeyboardLayoutManager.GetKeyValueAt() which expects bare key names. This mismatch caused incorrect key-to-LED mapping, making per-key RGB lighting non-functional.

When attempting to set colors on individual keys, the wrong key would light up. For example, selecting the W key in OpenRGB would actually light up the I key on the keyboard. The mapping was completely broken.

Solution

Added a GetCorrectHWValue() function that properly maps all 126 keyboard LEDs from their full key names to the correct hardware LED values. The function uses an unordered_map for hash lookup instead of the previous broken approach.

The mapping covers:

• Standard keyboard keys (F-row, number row, QWERTY, ASDF, ZXCV rows)
• Modifier keys (Ctrl, Alt, Win, Shift, Caps Lock)
• Arrow keys (Up/Left/Down/Right Arrow)
• Numpad keys (Number Pad 0-9, /, *, -, +, ., Enter)
• Navigation keys (Insert, Delete, Home, End, Page Up/Down)

Hardware Information

This fix was tested on:

• System: TUXEDO Stellaris 16 Intel Gen6 (SKU: STELLARIS16I06)
• Motherboard: TUXEDO GM6IXxB_MB2 (board model NB02)
• Keyboard Controller: ITE 8291 (USB device 048d:600b)
• Keyboard Layout: ISO QWERTY

Testing

After applying this fix, per-key RGB control works correctly. Each key now maps to its proper hardware LED position, allowing individual key color customization through the OpenRGB UI.

Changes

• RGBController_ClevoKeyboard.cpp: Added GetCorrectHWValue() function with full key mapping
• RGBController_ClevoKeyboard.h: Added function declaration
• ClevoKeyboardDevices.cpp: Reorganized comments for clarity

Additional Helper for TUXEDO Hardware

I've created a helper script that converts OpenRGB profiles to the kernel LED interface used by the tuxedo_keyboard driver on TUXEDO/Clevo laptops.

Why This Exists

On TUXEDO laptops, the Embedded Controller (EC) can turn off the keyboard backlight after idle periods. When it wakes, it reverts to firmware defaults instead of OpenRGB's USB HID settings.

The kernel LED interface (/sys/class/leds/rgb:kbd_backlight_*/multi_intensity) may provide better persistence through EC wake cycles.

The Helper Script

Location: tuxedo_keyboard_interface_helper.py in this branch

Features:

• Converts OpenRGB .orp profiles to kernel LED interface format
• Uses the same hardware LED mapping as RGBController_ClevoKeyboard
• Works with any OpenRGB profile
• Fully documented with usage instructions

Usage:

python3 tuxedo_keyboard_interface_helper.py [profile_name]

Hardware Compatibility

• TUXEDO laptops with Clevo per-key RGB keyboards (ITE 8291 controller)
• Linux with tuxedo_keyboard kernel driver
• This is NOT part of OpenRGB - it's an external helper for TUXEDO hardware

Testing

Tested on TUXEDO Stellaris 16 Intel Gen6 with per-key RGB (126 zones).

The script successfully:

• Parses OpenRGB .orp binary format
• Maps 102 LEDs using RGBController_ClevoKeyboard's hardware mapping
• Applies colors via kernel LED interface

Next step: EC timeout persistence test to verify if kernel interface colors survive EC wake.
