[RESEND] [PATCH] fujitsu-laptop: better handling of P8010 hotkey events

[Jonathan Woithe]

Resending ...


Hi Len

This patch (mostly from Peter Gruber) against 2.6.27-rc4 (but with the
interim P8010 patch from 2.6.27-rc6 applied) improves the handling of the
hotkeys for P8010 laptops by passing more accurate input events back to
userspace.  This is needed because the P8010 labels these buttons quite
differently to earlier laptops.  As part of this, a P8010-specific DMI
callback check has been implemented.  Finally there's some minor whitespace
cleanups from running the source through Lindent.

Please apply to acpi-test for 2.6.28.

[RESEND] [PATCH] fujitsu-laptop: better handling of P8010 hotkey events

[Jonathan Woithe]

Hi Len

Another resend in case this has been lost for some reason.


This patch (mostly from Peter Gruber) against 2.6.27-rc4 (but with the
interim P8010 patch from 2.6.27-rc6 applied) improves the handling of the
hotkeys for P8010 laptops by passing more accurate input events back to
userspace.  This is needed because the P8010 labels these buttons quite
differently to earlier laptops.  As part of this, a P8010-specific DMI
callback check has been implemented.  Finally there's some minor whitespace
cleanups from running the source through Lindent.

Please apply to acpi-test for 2.6.28.

[RESEND] [PATCH] fujitsu-laptop: better handling of P8010 hotkey events

[Jonathan Woithe]

Hi Len

Another resend in case this has been lost for some reason.


This patch (mostly from Peter Gruber) against 2.6.27-rc4 (but with the
interim P8010 patch from 2.6.27-rc6 applied) improves the handling of the
hotkeys for P8010 laptops by passing more accurate input events back to
userspace.  This is needed because the P8010 labels these buttons quite
differently to earlier laptops.  As part of this, a P8010-specific DMI
callback check has been implemented.  Finally there's some minor whitespace
cleanups from running the source through Lindent.

Please apply to acpi-test for 2.6.28.

please refresh so the patch applies to Linus' top of tree & resend.

checkpatch.pl clean would be nice -- though i do let some of those 80

Hi Len

Done.  At least I *think* this is against Linus' tree (I'm still learning
the whole git thing).  Find resulting patch below.

> column things slide where the cure would be worse than the disease...

I've cleaned up a few.  I can't see any sane way to resolve those which
remain.

This patch (mostly from Peter Gruber) improves the handling of the hotkeys
for P8010 laptops by passing more accurate input events back to userspace. 
This is needed because the P8010 labels these buttons quite differently to
earlier laptops.  As part of this, a P8010-specific DMI callback check has
been implemented.  Finally there's some minor whitespace cleanups from
running the source through Lindent.

Please apply to acpi-test for 2.6.28.

How about implementing getkeycode() and setkeycode() methods in the
driver and then using HAL to load appropriate keymap?

please see "SECTION 1" of Documentation/SubmittingPatches
dunno if this is why your last one didn't apply.

re: Lindent
please don't mix functional and style patches in the same patch,
they should be in a series of multiple patches.  otherwise the
style changes make it impossible to revivew the functional changes.

anyway, this one is in the test tree now.
perhaps you can address dmitry's question?

thanks,

Oops, sorry about that.  I was going to fix the diff paths before submitting
but in my haste to get it out I forgot about it.  In other words, the
failure to apply would have been due to the bogus local paths in the patch,
which were never meant to see the light of day.  Basically

  misc-linus -> linux-2.6-linus/drivers/misc
  misc-jmw   -> linux-2.6/drivers/misc

Yep.  Part of the problem in this case was that some of these changes came
from elsewhere.  They never separated it for me and at the time neither they
nor I had time to enforce the separation.  I'll be stricter next time. :-)

Thanks - I appreciate it.

> perhaps you can address dmitry's question?

Will do, but it might be a while before I have time to digest exactly what
it means and how to do it.  I'm going to be extremely short on time for
the next 3-4 weeks.

Sorry for the delayed response - this arrived after I left work on Friday
and I'm generally offline over the weekend.

This could work but I'll have to do some reading to find out precisely how
all this fits together (any pointers?).  It might be a while before I get
anything out though because I'm going to be extremely short on time over the
next 4 or so weeks.  In the meantime it'll be good to have this patch as
is since it greatly improves the hotkey support for the P8010 laptop (and I
note that Len has merged a rebased version of the patch in the meantime).

Thanks for the suggestion.

Regards

Please take a look at drivers/input/misc/wistron_btns.c for a sample
implementation and don't hesiatate contacting me if you have any
questions.
