[PATCH v2 0/3] asus_wmi: Support of ASUS TUF laptops on Ryzen CPUs

[Leonid Maksymchuk]

Hi,

this patch series adds support of ASUS TUF laptops on Ryzen CPUs to existing
asus_wmi platform driver and also fixes minor bug.

v2: fixed indentation.

Leonid Maksymchuk (3):
  asus_wmi: Fix return value of fan_boost_mode_store
  asus_wmi: Add support for fan boost mode on FX505DY/FX705DY
  asus_wmi: Set default fan boost mode to normal

[PATCH v2 1/3] platform/x86: asus_wmi: Fix return value of fan_boost_mode_store

[Leonid Maksymchuk]

Function fan_boost_mode_store should return number of bytes written
but instead it returns return value of kstrtou8 which is 0 if
conversion is succefull. This leads to infinite loop after any
write to it's SysFS entry.

[PATCH v2 2/3] platform/x86: asus_wmi: Support fan boost mode on FX505DY/FX705DY

[Leonid Maksymchuk]

On ASUS FX505DY/FX705DY laptops fan boost mode is same as in other
TUF laptop models but have different ACPI device ID and different key
code.

[PATCH v2 3/3] platform/x86: asus_wmi: Set default fan boost mode to normal

[Leonid Maksymchuk]

Set default fan boost mode to normal for multiple reasons:

1) existing code assumes that laptop started in normal mode and that is
   not always correct.
2) FX705DY/FX505DY starts in silent mode and under heavy CPU load it
   overheats and drops CPU frequency to 399MHz [1]. Setting fan mode to
   normal avoids overheating.

This can be refactored

if (!foo)
  return 0;
...
return bar(asus);

Leonid, I may not accept patches that contributor didn't even compile.
How had you tested?

Usual versioning
RFC [RFC v2, ...]
v1
v2, ...

Okay, next one will be v3 to avoid overlapping.

I'll take first patch later, but I also will give more comments to patch 2.
Please, give me time to review it properly.

The above differs only in one value to give and one value to set, I
suppose you may introduce an additional helper to it

This should be explained or even separated to another patch. It
changes behaviour of the original code, why?

I would prefer to see
 if (...)
  call with mode
else
  call with mode_2

below.

Thanks for review, I will do suggested changes.

Maybe it's better to add additional argument with index to
fan_boost_mode_check_present and
call it twice?

Original code also have this check to continue module initialization
when fan_boost_mode device
is not present. It's return value is checked in asus_wmi_add()
function and it'll fail module probing.
