[PATCH v2] platform/x86: hp-wmi: add support for OMEN 16-am2xxx boards

[Shuwen Bao]

The HP HyperX OMEN 16-am2xxx (DMI board 8F1C, 26C1 platform cycle,
Arrow Lake-HXR) is listed in the OMEN Command Center device
capability table with DisplayName "HyperX OMEN 16" and the
"PerformanceControl" feature, but is missing from the kernel's
omen_thermal_profile_boards whitelist. The thermal profile path is
therefore not enabled and the embedded controller keeps the CPU
pinned at the default frequency cap while running Linux.

Add 8F1C to the OMEN thermal profile board list. On this platform
the EC firmware also arms its own thermal profile revert timer (EC
offset 0x63, armed with 0x5a when performance is selected) and
switches back to the balanced profile once it expires, so also add
the board to omen_timed_thermal_profile_boards in order to have the
driver clear the timer and set the NOTIMER|TURBO flags when
switching to the performance profile. Testing further showed that
this board uses v0 commands, so also add it to
omen_thermal_profile_force_v0_boards.

Tested on a HyperX OMEN 16-am2xxx: after loading the patched hp-wmi
module the platform_profile interface is exposed, and switching to
the performance profile raises the CPU from a ~2.9 GHz (P-core) /
2.6 GHz (E-core) cap to ~4.8 GHz / ~4.3 GHz under a single-thread
load. The EC then reports the performance profile (0x31) with the
NOTIMER|TURBO flags set (0x62=0x06) and the revert timer cleared
(0x63=0x00); a plain write of the profile without those flags
instead arms the timer (0x63=0x5a) and the profile reverts to
balanced when it expires.

Thanks for the patch.

It is slightly unusual to see a board ID ending up in all 3 arrays.
(I believe no other board is present in the base, force v0 and
timed thermal profile simultaneously.)

But, it has been explained well in the commit message and tested,
so it is completely plausible.

Oh, and since the first revision of this patch had a corrupted
patch file (stated by the maintainer), I did apply it to check,
and it works.

LGTM.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

FYI [if applicable to your patch], as per Linus' policy change, also
fixes are mostly routed through for-next unless the fix is for a
commit introduced in the most recent cycle or is clearly a regression
fix.

Hi Shuwen Bao,

I was working a patch[1] involving omen_timed_thermal_profile_boards[]
and needed some diagostic info. Would you mind attaching the acpidump
for your board 8F1C?

Thanks!

Re: [PATCH v2] platform/x86: hp-wmi: add support for OMEN 16-am2xxx boards

[Shuwen Bao]

Hi Ilpo,

Following Krishna's review, I have sent a v3 of this patch which moves
board 8F1C from the thermal profile board list to
hp_wmi_feature_boards[], mapped to omen_v1_legacy_board_params:

https://lore.kernel.org/platform-driver-x86/
SI2PR04MB589508E55CCCD8E26E53E4DBA2942@SI2PR04MB5895.apcprd04.prod.outlook.com/

Since the v2 commit is currently applied in review-ilpo-next, could you
please drop it from that branch and take v3 instead? Otherwise the board
would end up listed in both places.

Sorry for the extra churn, and thanks for your time.

Best regards,
Shuwen Bao

Hi,

I've dropped the commit now but I'll process new patches later, not now.

> Sorry for the extra churn, and thanks for your time.

No problem at all, it happens all the time we need to reconsider 
something to get things done the best way possible.

Thanks.
