v1.4.0

v1.4.0 — 2026-08-19

• New: SMU SCLK range widened to 350–2230 MHz (from MastaG's kernel
  patch set), allowing userspace governors to drive the full clock range.
• New: FSR4 dp4a reassociation optimization now uses a selective
  approach — avoids catastrophic register spilling in pathological
  shaders while keeping the performance win on most kernels.
• New: Experimental display trial script (extras/display-trial/)
  for testing forced EDID and DP-1 enable — auto-reverts on 2nd reboot
  if unconfirmed. Useful for diagnosing boot video and session-switch
  display loss on DP-to-HDMI adapter setups.
• New: HDMI AC-3 encoding implementation guide for other operating
  systems (documents the ALSA a52 plugin + PipeWire approach).
• Fixed: Xbox adapter (xone-dkms) install now detects and installs
  the correct kernel headers package before building the DKMS module.
• Removed: GFX clock gating (--cg/--cg-unvalidated) flags and
  patches removed from the combined fix — the feature was experimental
  and unvalidated on BC-250 hardware.
