Description

Userspace for the Linux Dynamic Lighting LED class, paired with linux-unstable PR #17. Prefer asus::* sysfs when valid; keep hidraw/USB only when no DL node exists.

Draft / paired with the kernel series.

Node	Role
asus::keyboard	Aura keyboard DL
asus::lightbar	Chassis lightbar (enabled; no separate dimmer)
asus::logo	Lid logo when kernel registers it
asus::slash	Slash DL (effect/speed/power_states) or legacy attrs
asus::anime	AniMe Matrix (mono direct_buffer / direct_sample_size)
asus::xbox_logo	Xbox Ally Guide LED (brightness; DL effect/speed when present)

Commits

1. feat(rog-platform): add Dynamic Lighting sysfs helpers — DynamicLed, Slash/Xbox dual-path
2. feat(rog-aura): map Aura modes to Dynamic Lighting effect names
3. feat(asusd): prefer Dynamic Lighting for Aura, Slash and AniMe
4. docs: document Dynamic Lighting userspace ABI
5. feat(rog-control-center): list device-reported Aura modes
6. feat(aura): expose synced vs independent chassis zones in RCC — SupportedEffectTargets; Zone is edit-target only; colour/mode/speed/direction apply to that chassis node; AuraZone::None remains synced fan-out

Behaviour

• DL node requires effect, effect_index, zone_type, led_count
• Prefer kernel direct_sample_size; fall back to mono for AniMe/matrix
• Under DL, legacy Key1–4 / Bar* are aliases; Logo maps to asus::logo
• AuraZone::None fans out (synced); Key1 / BarLeft / Logo apply independently
• SupportedBasicZones stays empty under DL; UI uses SupportedEffectTargets
• Zone dropdown does not write LEDs on select — pick Zone, then change colour/mode/speed/direction
• Slash boot/sleep/shutdown use power_states when advertised

Verification

• cargo check / clippy / cranky on touched crates
• Docs updated
• D-Bus Key1/BarLeft independent on G614PR
• Restart RCC from ~/.local/bin (or reinstall to /usr); Zone Keyboard then change colour → lightbar unchanged

Summary

Summary by CodeRabbit

• New Features
  • Added Dynamic Lighting support for compatible keyboard, lightbar, AniMe, and Slash LEDs, with available effects, brightness, color, and power controls.
  • Added Direct and Reactive Aura modes, updated mode names, and improved brightness scaling across devices.
  • Added support for Xbox logo lighting.
• Bug Fixes
  • Improved device detection and lighting restoration after sleep, resume, and configuration reload.
  • Invalid lighting data and unsupported controls now return errors instead of silently succeeding.
• Documentation
  • Added a guide to Dynamic Lighting behavior and legacy fallbacks.

The PR adds Dynamic Lighting and LED sysfs interfaces, integrates them with Aura, AniMe, and Slash control paths, and updates device detection. It also changes Aura mode mappings and UI labels, documents Dynamic Lighting behavior, and adjusts HID report handling.

Changes: LED backend integration

Layer / File(s)	Summary
LED interfaces and mode contracts rog-platform/src/dynamic_led.rs, rog-platform/src/slash_led.rs, rog-platform/src/xbox_logo_led.rs, rog-platform/src/lib.rs, rog-platform/src/hid_raw.rs, rog-aura/src/builtin_modes.rs	Adds sysfs-backed LED interfaces, brightness and mode conversions, Dynamic Lighting effect mappings, and HID output-report detection. Platform write errors now distinguish missing attributes from other I/O errors.
Device detection and backend selection asusd/src/aura_types.rs, asusd/src/aura_manager.rs, rog-slash/Cargo.toml, rog-slash/src/data.rs	Detects Dynamic Lighting and Slash LED nodes, adds Xbox logo LED detection, and changes HID probing to use per-probe handles. Slash model selection now uses USB product IDs instead of DMI data.
Laptop Aura control paths asusd/src/aura_laptop/mod.rs	Routes Aura effects, brightness, power states, and direct RGB frames through Dynamic Lighting when available. Retains legacy TUF and hidraw paths when Dynamic Lighting is absent.
Aura D-Bus and lifecycle integration asusd/src/aura_laptop/trait_impls.rs	Reports Dynamic Lighting-supported modes and zones, uses controller brightness methods, and restores power states, brightness, and mode during reload and resume.
AniMe backend routing asusd/src/aura_anime/mod.rs, asusd/src/aura_anime/trait_impls.rs	Routes AniMe operations through Dynamic Lighting when present and preserves the USB path. D-Bus setters and system-event handlers use backend-aware helpers.
Slash LED sysfs control asusd/src/aura_slash/mod.rs, asusd/src/aura_slash/trait_impls.rs	Replaces Slash packet writes with LED sysfs operations. Power-state setters return NotSupported, and reload propagates LED-operation errors.
UI, documentation, and supporting updates rog-control-center/ui/types/aura_types.slint, rog-control-center/translations/en/rog-control-center.po, docs/SUMMARY.md, docs/usage/dynamic-lighting.md, asusctl/examples/anime-diag.rs	Updates Aura mode labels and controls, adds the Dynamic Lighting guide to the documentation index, and changes the AniMe diagnostic example to fill selected rows.

Full details: Title check

Explanation

The title names the main change: Dynamic Lighting support through asus::* sysfs nodes, with synced and independent zone handling. The changeset adds DynamicLed, Slash/Xbox LED helpers, and Aura/AniMe/Slash routing through Dynamic Lighting, which matches the title. The title is concise, but it is long and uses the scoped 'feat(aura)' prefix. Under the tone instructions, the response uses a Linus Torvalds voice for the explanation.

Full details: Description check

Explanation

The description follows the template's main sections. It has a summary of the change, a commit list, a behaviour section, and a verification checklist. The Fixes issue line is absent, and the Tested Hardware & Environment section is not filled in (model, distro, kernel). It also omits the template's checklist items for cargo fmt, comments, and documentation review, although the verification section partly covers these. The description is mostly complete, so this check passes.

minimal, and validate.

Inline comments:
Review comments at @asusd/src/aura_anime/mod.rs:
- Line 246: Update the custom playback and builtin-animation paths around
set_builtins_enabled to use the configured AniMe brightness instead of forcing
Brightness::Med, keeping runtime brightness consistent with config. Ensure frame
writes do not re-enable the display when its configured brightness is Off, while
preserving the existing playback and animation behavior.
- Line 246: Update run_thread, reload, and the wake handler to control built-in
animations without powering off USB AniMe displays before custom frames are
written. Preserve display power while boot, wake, and system animations run, and
establish the appropriate built-in-control behavior separately from display
power.
- Around line 164-169: Update the helper containing the self.dynamic block so it
does not reacquire the AniMe config mutex while the BuiltinsEnabled setter holds
it. Adjust the call flow to reuse the already available configuration or ensure
the caller releases the mutex before invoking the helper, while preserving the
existing built-in animation settings behavior.

Review comments at @asusd/src/aura_anime/trait_impls.rs:
- Around line 163-170: Update the flow around apply_builtin_animations and
set_builtins_enabled so enabling built-ins uses the newly supplied settings as
the effective animation selection. Ensure the enable operation does not restore
the previous configuration and that the saved settings and kernel selection
agree immediately.

Review comments at @asusd/src/aura_laptop/mod.rs:
- Line 454: Update the node handling around direct_rgb_payload so a frame with
an incompatible LED count skips that node and lets the lightbar be tried.
Preserve InvalidValue when the frame is malformed and no node accepts it; do not
treat size mismatch as success.
- Around line 356-361: Update the `set_power_states` path so an empty `states`
list is sent as a nonempty payload that the kernel parses as an empty list;
bypass `write_attr_string` for this case because it trims whitespace. Preserve
the existing unsupported-request handling and normal payload behavior for
nonempty `states`.
- Around line 561-571: Update the packet reconstruction loop over packets so
each 0xbc payload is placed according to that packet’s start index rather than
appended in arrival order. For partial updates, initialize the reconstructed
frame from the current frame and overwrite only the addressed LED groups,
preserving untouched LEDs.
- Around line 168-172: Update the direction-handling guard around
led.set_supported_direction so validation and writes occur only when the
selected effect uses direction. Static effects must bypass direction handling
regardless of the requested direction, while directional effects must retain
supported-direction validation.
- Around line 348-364: Reconcile power-state requests for each physical LED node
before writing, rather than letting iteration order overwrite them. Update the
loop using power_flags_for_state and dynamic_nodes_for_power_zone to resolve
conflicting zone aliases so a disabled Keyboard sleep setting cannot be
re-enabled by a later Logo entry, then apply the resolved states once per node.

Review comments at @asusd/src/aura_laptop/trait_impls.rs:
- Line 208: Update the effect replay logic around supports_dynamic_zone so a
stored None-zone keyboard effect is not treated as replaced by a BarLeft
lightbar effect. Preserve and replay the keyboard and lightbar node effects
independently during reload and resume.
- Around line 199-207: Update the effect-support check in the dynamic-lighting
branch to use the lightbar node for BarLeft and BarRight requests, while
preserving the existing keyboard-node validation for other zones. Ensure
bar-zone requests are accepted when the lightbar supports the effect, regardless
of keyboard support.
- Around line 103-115: Update the Dynamic Lighting mode discovery path around
AuraModeNum::all() and supports_effect so each advertised mode also gets an
initialized configuration entry retained in the mode data used by led_mode_data
and reload. Preserve the existing support check and returned list of advertised
modes.

Review comments at @asusd/src/aura_manager.rs:
- Around line 169-174: Update the hotplug registration flow around hid_key and
dbus_path_for_dev to reconcile an existing Aura object when a USB device
re-enumerates but its selected Dynamic Lighting node remains available. Reuse or
update the existing owner rather than registering a duplicate, and ensure only
one resume task can write to that node.
- Around line 446-447: Update the fallback around
DeviceHandle::maybe_laptop_aura so it registers an Aura object only when a
usable lighting backend exists: validate that a Dynamic Lighting node or a
legacy RGB-capable backlight is available before registration, and skip
registration when neither is present.

Review comments at @asusd/src/aura_slash/trait_impls.rs:
- Around line 157-158: Update the Slash backend capability handling around
set_show_on_boot so it reports visibility controls as unsupported; ensure the UI
disables or hides all six switches for this backend and does not retain an
attempted value when a change cannot be saved.

Review comments at @asusd/src/aura_types.rs:
- Around line 45-65: Update DeviceHandle::maybe_slash so a missing Slash sysfs
LED does not prevent supported legacy GA403 HID or USB access from creating a
controllable Slash object. Reuse the existing HID or USB discovery and control
path, preserving brightness, interval, and mode controls; establish the
available APIs before choosing the fallback, and keep sysfs discovery for
devices that provide the LED node.

Review comments at @docs/usage/dynamic-lighting.md:
- Around line 60-62: Update the Slash documentation near the `asus::slash` sysfs
description to distinguish reads from writes: state that D-Bus
boot/sleep/shutdown/battery/lid persistence properties return stored
configuration values when read, while writes return `NotSupported`.
- Around line 83-85: Update the SG_IO statement in the Dynamic Lighting
documentation to accurately note that the public rog_scsi API, including Device,
Task, and sg, remains available and Device::perform still issues SG_IO. Present
the Dynamic Lighting sysfs ABI as the recommended backend without claiming the
existing API was removed.

Review comments at @rog-aura/src/builtin_modes.rs:
- Around line 243-250: Update `Speed::to_dynamic_speed` so Low, Med, and High
map to the ASUS node’s advertised 1–3 range, ensuring the selected value passes
validation and the effect can be written.

Review comments at @rog-control-center/ui/types/aura_types.slint:
- Line 91: Update the Basic aura mode dropdown so its Direct option is available
only when the UI can supply frames; omit Direct when no frame producer is
active, while preserving it when frames can be supplied.

Review comments at @rog-platform/src/hid_raw.rs:
- Around line 24-28: Update the composite-keyboard interface selection flow to
choose the Aura-capable interface before deduplicating by USB parent, so an
earlier non-RGB input interface cannot suppress it. Keep supports_output_report
focused on checking output report IDs; do not use it as a substitute for Aura
capability detection.

Review comments at @rog-slash/Cargo.toml:
- Line 16: Restore the `detect` Cargo feature and the `SlashType::from_dmi` API
for the existing 6.5.0 version. Preserve the former method’s signature and
DMI-based board detection behavior; do not substitute `from_usb_product`.
