charset="utf-8" HP Omen 16-wf1xxx (board ID 8C78) currently sends the incorrect Victus-specific thermal profile values via WMI, leading to a logical inconsistency when switching between platform profiles. The driver currently uses Victus S values: 0x00 =3D> Balanced / Low-Power 0x01 =3D> Performance However, Omen Gaming Hub logs / EC register inspection on Windows shows that this board is intended to use: 0x30 =3D> Balanced / Low-Power 0x31 =3D> Performance This patch corrects the thermal profile command values to match the values observed from Omen Gaming Hub logs. The performance benchmarks and peak power draw (from both CPU and GPU) show no observable change with this correction (suggesting that the firmware is currently tolerant of the incorrect values). However sending the correct values prevents potential regressions after future firmware updates. Refactor victus_s_thermal_profile_boards from a list of strings to a dmi_system_id table and move the lookup to module init. The new struct thermal_profile_params is used to store board-specific WMI parameters, allowing the driver to cache these values in a static pointer. This avoids repeated DMI string comparisons and allows marking of DMI table as __initconst. Testing on HP Omen 16-wf1xxx (board 8C78) confirmed WMI codes 0x30/0x31 are now sent, resolving the logical inconsistency and ensuring the value visible in EC registers match the Windows state for this profile. Fixes: fb146a38cb11 ("platform/x86: hp-wmi: Add Omen 16-wf1xxx fan support") Signed-off-by: Krishna Chomal --- Changes in v3: - Fixed minor formatting issues. - Renamed struct field `eco` to `low_power` for consistency. - Marked the DMI table as __initconst. - Moved DMI lookup to hp_wmi_init() and save the active thermal profile params. - Added a static boolean flag to optimize is_victus_s_thermal_profile(). Changes in v2: - Refactored `victus_s_thermal_profile_boards` to use `struct dmi_system_id` - Implemented `driver_data` to handle thermal profile parameters, replacing the conditional checks in `platform_profile_victus_s_set_ec` - Moved enum definitions for thermal profile values earlier in the file to support the new `struct thermal_profile_params`. --- drivers/platform/x86/hp/hp-wmi.c | 179 ++++++++++++++++++++++--------- 1 file changed, 127 insertions(+), 52 deletions(-) diff --git a/drivers/platform/x86/hp/hp-wmi.c b/drivers/platform/x86/hp/hp-= wmi.c index f4ea1ea05997..24d065ddfc6a 100644 --- a/drivers/platform/x86/hp/hp-wmi.c +++ b/drivers/platform/x86/hp/hp-wmi.c @@ -53,6 +53,66 @@ MODULE_ALIAS("wmi:5FB7F034-2C63-45E9-BE91-3D44E2C707E4");
