fix(rog-aura): support TUF FA401 series keyboard power states#353idobutidont wants to merge 1 commit into
Conversation
Add FA401 series support for the TUF keyboard RGB power-state controls and sleep-backlight handling. This requires the corresponding asus-wmi kernel change to fully work: Link: https://lore.kernel.org/platform-driver-x86/20260902032353.16106-1-idotohors@gmail.com
📝 SummarySummary by CodeRabbit
WalkthroughThe change adds FA401 Aura support, maps TUF lightbar settings to the Keyboard zone, preserves discovered configuration fields, and activates safer sleep/wake event handling. ChangesTUF Aura power and sleep handling
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Suspend, wake, shutdown, and configuration updates can deadlock or leave keyboard lighting state inconsistent, potentially making Aura controls unavailable until recovery. The lock-order issue should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

- Line 49: Update the shutdown callback activated by create_tasks so it reads
brightness while holding config, releases config, and only then locks backlight.
Apply the same config-then-backlight ordering across the sleep/wake callback and
Aura::update_config, ensuring no Aura path acquires these mutexes in the reverse
order.

Fix the mutex order before starting this task.
This call activates the shutdown callback. That callback locks backlight and then config. The sleep/wake callback and Aura::update_config lock config and then backlight. If shutdown overlaps one of those operations, both tasks can wait on the other mutex indefinitely.
Read brightness while holding config, release config, then lock backlight in the shutdown callback. Use this lock order in all Aura paths.
