2024-07-09platform/x86: hp-wmi: Fix platform profile option switch bug on Omen and ↵Alexis Belmonte
Victus laptops Fix a platform profile option switch/getter bug on some Omen and Victus laptops dismissing userspace choice when selecting performance mode in inadequate conditions (e.g. by being disconnected from the AC power plug) by - hooking an ACPI notify handler through the omen_register_powersource_event_handler method that listens to AC power source changes (plugging in/out the AC power plug) - keeping an intermediate active_platform_profile variable that is set when userspace changes the platform profile setting - restoring the selected platform profile kept in active_platform_profile when AC power is plugged back into the laptop through the power_supply_is_system_supplied call check, unless if the user decided to alter the platform profile mid-way Add a dependency to the POWER_SUPPLY subsystem to be able to check for power_supply_is_system_supplied. Introduce intermediary functions to leverage platform profile <-> internal thermal profile translation code from platform_profile_omen_set and callers. These changes makes the module compliant with the principles defined in the Platform Profile Selection page of the Kernel documentation on those kind of laptops; which is to not "(...) let userspace know about any sub-optimal conditions which are impeding reaching the requested performance level". Since the Omen and Victus laptops share the same embedded controller system, the fix is applicable to both categories of laptops.

2024-02-06platform/x86: hp-wmi: Add thermal profile support for 8BAD boardsAlexis Belmonte
Add 8BAD to the list of boards which have thermal profile selection available. This allows the CPU to draw more power than the default TDP barrier defined by the 'balanced' thermal profile (around 50W), hence allowing it to perform better without being throttled by the embedded controller (around 130W). We first need to set the HP_OMEN_EC_THERMAL_PROFILE_TIMER_OFFSET to zero. This prevents the timer countdown from reaching zero, making the embedded controller "force-switch" the system's thermal profile back to 'balanced' automatically. We also need to put a number of specific flags in HP_OMEN_EC_THERMAL_PROFILE_FLAGS_OFFSET when we're switching to another thermal profile: - for 'performance', we need to set both HP_OMEN_EC_FLAGS_TURBO and HP_OMEN_EC_FLAGS_NOTIMER; - for 'balanced' and 'powersave', we clear out the register to notify the system that we want to lower the TDP barrier as soon as possible. The third flag defined in the hp_thermal_profile_omen_flags enum, HP_OMEN_EC_FLAGS_JUSTSET, is present for completeness. To prevent potential behaviour breakage with other Omen models, a separate omen_timed_thermal_profile_boards array has been added to list which boards expose this behaviour. Performance benchmarking was done with the help of silver.urih.com and Google Chrome 120.0.6099.129, on Gnome 45.2, with the 'performance' thermal profile set: | | Performance | Stress | TDP | |------------------|-------------|------------|-------| | with my patch | P84549 | S0.1891 | 131W | | without my patch | P44084 | S0.1359 | 47W | The TDP measurements were done with the help of the s-tui utility, during the load. There is still work to be done: - tune the CPU and GPU fans to better cool down and enhance performance at the right time; right now, it seems that the fans are not properly reacting to thermal/performance events, which in turn either causes thermal throttling OR makes the fans spin way too long, even though the temperatures have lowered down - expose the CPU and GPU fan curves to user-land so that they can be controlled just like what the Omen Gaming Hub utility proposes to its users; Signed-off-by: Alexis Belmonte <alexbelm48@gmail.com> Link: https://lore.kernel.org/r/ZbucvX2rRdqRgtcu@alexis-pc Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
2024-02-06platform/x86: hp-wmi: Tidy up module source codeAlexis Belmonte
This commit performs four things: - fix up the GUID string inconsistency (lower case 'e') from the WMI module alias declaration/macro definition - separate GUID macros from the embedded controller offset macros - rename the description of the module to better represent what it actually achieves as a whole - add a space right before the '*' pointer qualifier to match the other array declarations This also prepares the terrain for integrating support work for boards identified as '8BAD', which corresponds to HP's Omen 17 ck2xxx models.

2023-12-11platform/x86: hp-wmi: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-05-09platform/x86: hp-wmi: Add HP Envy special key supportJonathan Singer
Previously, some support for certain keys on the HP keyboard has been added already in commit 3ee5447b2048 ("platform/x86: hp-wmi: Handle Omen Key event"), however this as tested did not allow even the fn+esc key on my HP Envy which uses the same keycode on my HP Envy x360 laptop to work --the keycode rather than being passed in as a separate int from WMI, was being passed in as the event_data for the HPWMI_OMEN_KEY event. This patch, as tested was able to properly get the keycode for fn+esc, and for fn+f12 which is supposed to be a programmable key according to HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key, however it did not previously have an entry in the sparse keymap. This patch preserves the original HPWMI_OMEN_KEY behavior for laptops that use it by only taking the keycode from the event_data only when the event_data is nonzero.

2023-05-09platform/x86: hp-wmi: Add HP WMI camera switchJonathan Singer
Previously, when the camera toggle switch was hit, the hp-wmi driver would report an invalid event code. By adding a case for that in the event handling switch statement we can eliminate that error code and enable a framework for potential further kernel handling of that key. This change was tested on my HP Envy x360 15-ey0023dx laptop, but it would likely work for any HP laptop with a camera toggle button. Now we emit an SW_CAMERA_LENS_COVER event, on a device that gets created on the first such event so as to not report incorrectly the state of the camera shutter before we can know its state.
