TLC (Twilight Commander) was missing from both ISO configs. Added
tlc = {} to [packages] in redbear-mini.toml and redbear-full.toml.
Created missing symlink: recipes/tui/tlc -> ../../local/recipes/tui/tlc.

# ── Red Bear OS — Intel GPU Bounded Validation ──────────────────────────────
|
|
# Proves display-path correctness for the Intel i915-redox driver backend.
|
|
#
|
|
# Stages (run in increasing invasiveness order):
|
|
# S0 PCI device presence — driver probe gate
|
|
# S1 MMIO register readback — BAR2 mapping proof
|
|
# S2 Connector enumeration — display topology discovery
|
|
# S3 EDID read (DP AUX / GMBUS) — real hardware communication
|
|
# S4 Bounded modeset + page flip — full display pipeline proof
|
|
# S5 Vblank counter advancing — interrupt delivery proof
|
|
#
|
|
# Usage:
|
|
# ./test-intel-gpu.sh # All pass-through checks
|
|
# ./test-intel-gpu.sh --mode 1920x1080@60 # With bounded modeset proof
|
|
# ./test-intel-gpu.sh --pci 0000:00:02.0 # Specific PCI device
|
|
# ./test-intel-gpu.sh --stage S2 # Stop after specific stage
|
|
# ./test-intel-gpu.sh --no-modeset # Skip S4/S5 (safe on unknown display)

|
Bounded Intel GPU validation harness. Proves display-path evidence

|
Options:
|
|
--mode WxH@refresh Bounded modeset target (e.g., 1920x1080@60)
|
|
--pci BB:DD.F PCI device address (default: auto-detect)
|
|
--stage S0-S5 Stop after specified stage
|
|
--no-modeset Skip modeset+vblank stages (S4/S5)
