FYI When you submit v3, you don't need to add "new patches on top" for your feedbacks to the new driver, they can roll into the patch introducing hp-cfg.  Just make sure you include a changelog under your cut line to indicate you changed these from vX->vY

I suspect that Hans will also want you to split the driver up into smaller bite-size patches to make his review easier as well, but I'll let him advise how he wants it done.

Please see comments to previous source comments.

Thanks.  If you make this change for v2, I can make the matching change
in fwupd so that if it notices current_value permissions like this that
it shows read only there too.

Submitted the recommended changes for review in v2


Thanks, looks good.

Submitted a patch to improve the friendly display name for
few numbers of attributes associated with ‘Schedule Power-ON.’  BIOS
assign names such ‘Tuesday’ to an attribute. The name is correct, but
it is not descriptive enough for the user.  Under those
conditions a portion of the path data value is appended to the attribute
name to create a user-friendly display name.

For instance, the attribute name is ‘Tuesday,’ and the display name
value is ‘Schedule Power-ON – Tuesday’

Looks good


Presumably if this is going into it's own directory you should move all
platform-x86 HP drivers to this directory earlier in the series too.

The other drivers named HP-WMI and HP_ACCEL  were written by third
party members and not by HP.   It is for this reason and because of
the number of files, only hp-bioscfg was placed in a separate
directory.   Let me know If my reasoning is not valid enough  and I
will keep the files in a separate directory and move the selection to
the main list.    In addition, Moving  HP-WMI and HP_ACCEL drivers
from x86 directories fall outside of the scope of these changes,
Correct?


There is no distinction who writes a driver.  I think either you keep this driver in the root of drivers/platform/x86 or you put all the HP drivers in drivers/platform/x86/hp.

I think if you're going to put this driver in the sub-directory "hp", then the first patch in this series should be to move those drivers to that sub-directory.  The second patch should be to introduce your new driver.

I see this driver has a lot of separate files, so what should happen here IMHO is:

1. a preparation patch adding a hp subdir moving the existing hp drivers there

This will be a separate patch but not an obstacle to gain approval of
hp-bioscfg driver, correct?

Right, this is just shuffling things around a bit because as we get
more and more drivers having them all in one dir becomes a bit
unwieldly.

The AMD drivers just underwent this very recently too, as did Intel about 6 months before. If you want an example of what they did you can use this to reference the AMD one:

https://github.com/torvalds/linux/commit/ef233eafe5adc54ddc39a1b6cc483dddc744bf97



2. but this driver in a subdir of the hp subdir, so put all its files under:

drivers/platform/x86/hp/hp-bioscfg

so as to keep the files together and separate from other hp drivers.

Can you please clarify..

Do I need to start a new review with only two patches described earlier?

1. a preparation patch adding a hp subdir moving the existing hp drivers there
2. Squash (current version v1 and v2 changes) into one

Ah, no, splitting step 2 as you did into multiple patches is fine,
reviewing multiple small patches typically also is easier. So keeping
the addition of the hp-bioscfg split into multiple patches is good.

The split right now is along changes requested on v1 -> v2 rather than along making the driver into functional pieces.


The point which I was trying to make is to put all the files
for hp-bioscfg in their own sub-sub-dir and not mix them with
the other driver files in a single hp dir.

Regards,

Hans
