In `@asusd/src/asus_armoury.rs`:
- Around line 339-370: Replace each repeated get_mut-then-insert update of
tuning.group in the shown restore logic, including the corresponding sites later
in the same implementation, with a direct HashMap::insert using the same key and
value. Preserve the existing branches and value-selection behavior while
removing the redundant conditional updates.
- Around line 482-494: Update the property-setting function to read the platform
profile and power state once at its start, then reuse those captured values for
both tuning-enabled evaluation and selecting the persistence group. Remove the
later get_platform_profile and get_online reads so hardware writes and config
updates use the same profile and power state.
- Around line 373-375: Update the wildcard arm handling Immediate and Bios
attributes after self.attr.restore_default() succeeds by synchronizing
config.armoury_settings: remove the persisted entry or replace it with the
attribute’s post-restore value, then persist the updated configuration so reload
cannot reapply the stale user value.
- Around line 235-247: In start_attributes_zbus, replace the break used when
attr.reload().await fails with continue so later Armoury attributes still
register. Also cache attribute.property_type() once before the apply-value
handling and reuse that cached value instead of calling the method repeatedly.
- Around line 335-340: Guard missing PPT defaults in all affected paths: in
asus_armoury.rs lines 335-340, update set_config_or_default to skip attributes
whose default is not AttrValue::Integer; in asus_armoury.rs lines 718-735, make
set_enable_ppt_group skip the attribute when no stored tune exists and its
default is not AttrValue::Integer; in asusd/src/ctrl_platform.rs lines 787-791,
make restore_default return fdo::Error::NotSupported before calling
self.attr.restore_default() when the default is unavailable. Ensure none of
these paths calls set_current_value or saves current_value as a fallback for
missing defaults.
In `@asusd/src/ctrl_platform.rs`:
- Around line 792-806: Update the configuration-setting flow around the
attr.set_current_value loop to track whether any tune value changes, including
rejected-value fallbacks, then call config.write() once after the loop only when
a change occurred. Remove reliance on the earlier write so fallback values are
persisted explicitly without writing when no values changed.
In `@rog-platform/src/asus_armoury.rs`:
- Around line 365-366: Update the asusctl armoury set command to reject or skip
read-only attributes such as charge_mode before calling set_current_value, and
provide a clear diagnostic for unsupported writes. Preserve write behavior for
attributes that expose writable handlers.
- Around line 268-276: Add a doc comment to
FirmwareAttributeType::should_persist_armoury_setting documenting that it
identifies attributes persisted specifically in armoury_settings, while Ppt is
persisted through profile tuning groups and therefore returns false; preserve
the existing behavior and ordering dependency at its callers.
Apply the same fix in `@rog-platform/src/asus_armoury.rs` around lines 268 - 276:
The commit block should directly use the persistence predicate rather than
depending on the current enum match and early returns.

Line 516 and previous: this PR won't solve the issue anyway because the problem must be elsewhere. Stale value from a previous in correct version of the software? |

No: my previous commemt is incorrect. Disregard. |

However storing a value in config, before tuning is applied is wrong because user can write a wrong value in battery while tuning is disabled. All is well. Enable tuning. Reboot. Now the original issue is back. |

Can you explain how you have recreated the issue and confirmed this fix works? |

Same way as #132: turned off the laptop while connected to energy and turned it on while on battery triggers the same problem. As for fixing this method works but it is still far from perfect |

@coderabbitai full review. Avoid the break comment as stated before (we want break to remain as is to prevent any wrong value to make a shit of asusd). |

The `break` enforces an atomic startup invariant. PPT firmware rejections are handled inside `reload` as warnings and must return `Ok(())`, so they do not trigger the `break`.

For active devices, Linux frequency sources are i915 `gt_act_freq_mhz` / `gt_cur_freq_mhz` in MHz and amdgpu hwmon `freq1_input` in Hz; `gpu_current_freq` is not a valid Linux source for this helper.

Fixes OpenGamingCollective#132 by ensuring unappliable or power-restricted tuning values are not saved to memory/disk or blindly written to sysfs. Reject PPT attribute modifications when profile tuning is disabled, handle graceful self-healing fallback when loading configs, and mark charge_mode as ReadOnly in rog-platform.

Description
This PR solves the root cause of issue #132 where
asusdfailed on battery startup due to unapplicable PPT tuning values being persisted and re-applied to sysfs.Key Changes:
asusd(Armoury Controller & Tuning):set_current_value: Validate the hardware write on sysfs before updatingArc<Mutex<Config>>in RAM and serializing to/etc/asusd/asusd.ron. If the kernel/firmware rejects the write (e.g.EINVALon battery), the function returns an error immediately and leaves in-memory state and disk config uncontaminated.set_config_or_default: When generating default tuning values on startup, if the static driver default (e.g.nv_dynamic_boost = 20) is rejected by firmware on the active power state,asusdfalls back to querying the active hardware value (attr.current_value()) instead of storing an invalid default.reload: Differentiates PPT power-state restrictions (logging an informative warning) from fatal attribute errors, preserving the fail-fastbreak;policy without causing false-positive crashes at boot.rog-platform(Armoury Driver Model):charge_modeasReadOnly(FirmwareAttributeType::ReadOnly) since it is a0444read-only sysfs node in theasus-armourykernel driver with no store handler.asusd(Platform Controller):set_enable_ppt_group: Falls back to active hardwarecurrent_valueif restoring a saved tuning value fails on battery.Fixes #132
