feat(asusd): adding battery level custom slash animation (#68) - #329
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe PR adds a battery-level mode for Slash lighting. It generates brightness patterns from battery capacity, sends custom USB frames, manages periodic updates in ChangesSlash battery-level mode
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Battery-level mode can remain enabled while normal animation runs, and a failed device setup can be reported and saved as successful. These bounded correctness issues should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Shouldn't we emit a warn here? Using an .ok() suppress every possible warn without even registering it on journal

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Restart battery rendering only when Slash is enabled.
This lifecycle is broken. Disabling Slash stops the task but preserves battery_level_mode. Re-enabling Slash never restarts the task, so the UI still shows battery mode enabled while the normal animation runs.
At startup, Lines 33-35 also start the task when enabled is false. Gate startup on both flags. After a successful enable, restart the task when battery_level_mode is true.
Also applies to: 58-60

Do not persist battery mode before custom-buffer arming succeeds.
Lines 198-200 save battery_level_mode = true before start_battery_level_task can fail. If USB arming fails, the setter still returns success, the UI shows success, and the saved configuration claims battery mode is active after the daemon restored normal hardware state.
Make task startup return an error. Persist true only after arming succeeds. Return that error through the D-Bus setter.

Why is this being reviewed when in a draft state. Did you discuss with the PR author? |
No, not really. I wanted to be sure nothing was left behind from my previous check |
I mean your first review was also while this was here as a draft PR. So I was wondering if he asked for a review and it's in draft because he wanted feedback before marking this as ready. If it's draft, it means he's still working on it |

Description
Port GHelper's battery slash animation. Computes a per-segment brightness buffer showing battery percentage on Slash bars, plus the custom-pattern USB protocol (select/enable/commit/frame) needed to push it to the device instead of a built-in animation.
asusd
rog-slash/src/data.rs: addsbattery_pattern(length, percentage, max_brightness), used to build the slash pattern based on the user battery level and themax_brightness.rog-slash/src/usb.rs: adds the reverse-engineered "battery level" custom-pattern protocol from GHelper to arm the custom-pattern region, andslash_pkt_custom_frameto push a raw per-segment brightness frame. Also addssegment_count(slash_type)(7 segments for base models, 35 for enhanced slash GU605/GU606/GU405 models).-
