            Bug ID: 221150
           Summary: [BUG] hp-wmi: OMEN 16-k0xxx (board 8A4D) –
                    verification of platform_profile and EC register
                    behavior
           Product: Drivers
           Version: 2.5
          Hardware: Intel
                OS: Linux
            Status: NEW
          Severity: low
          Priority: P3
         Component: Platform_x86
          Assignee: drivers_platform_x86@kernel-bugs.osdl.org
          Reporter: qwqgong@gmail.com
        Regression: No

EC dump,dmesg_full,acpidump.

Hardware:
   Laptop: HP OMEN Laptop 16-k0xxx (Omen 8 Pro)
   Board ID: 8A4D
   CPU: Intel Core i7-12700H
   BIOS Version: F.28 (2025-08-13)
Software:
   Distro:  CachyOS
   Kernel: 6.19.3-2-cachyos
Problem summary:
   The hp-wmi driver registers correctly as a platform profile handler on this
board (8A4D). I am providing baseline diagnostics including an EC dump and
dmesg logs to help maintainers verify if the current WMI query implementation
correctly maps to this specific model's thermal and performance profiles.
Actual Results:
   The platform_profile file accepts the input, but there is no change in fan
RPM or thermal management behavior. No audible fan ramp is observed even when
"performance" is selected.
❯ cat /sys/firmware/acpi/platform_profile_choices
cool quiet balanced performance
Expected Results:
   Switching to "performance" should trigger the firmware's high-performance
thermal map and increase fan aggressiveness, similar to the "Performance Mode"
in the OMEN Command Center on Windows.

Hi,

Your board, 8A4D is not currently present in any whitelist in the hp-wmi
driver. As a result, it defaults to legacy Omen WMI interface to register the
platform-profile.

From your Omen Gaming Hub logs and EC dump, it is evident that your board
requires the newer Victus S style WMI queries for platform-profile switching
(and fan related activities), instead of the legacy queries.

Can you please apply the below patch and test the following:
1. Check dmesg for successful registration message:
   "hp_wmi: Registered as platform profile handler"

2. Verify that fan RPM is readable and controllable via sysfs
(/sys/devices/platform/hp-wmi/hwmon/*).

3. Verify that on changing platform profile, and it does physically change the
amount of power drawn in the CPU/GPU.

Hello Krishna,

I successfully applied the patch to the mainline RC kernel and thoroughly
tested it on my board (8A4D). The results are fantastic:

 Sysfs nodes are populated correctly (performance, balanced, low-power).
Switching to the "performance" profile works flawlessly and successfully
unlocks the hardware power limits—I can confirm the CPU reaches 115W under full
load!

The patch brings full and essential support for the Omen 8A4D board. Thank you
so much for your hard work!

Hi Qinfeng Wu,

The patch for this board has been merged into the mainline kernel. You can find
the commit here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=435da773966c80e1b2b6aea75460ef0e893fd9e9

It should show up in the next release (likely 7.0 or a 6.x stable backport).
Since the patch is upstream, feel free to close this report as "Resolved
Fixed".

Thanks
