Any news about this? I have no problem throwing away the whole patch set
and use a different approach, if there is any :)
And I need one, because I have a patch pending for a MIDI/Controller
device which is something like a drum computer control device, and this
one has more ABS information channels than currently supported by the
input stack.
OTOH, the current plan is to use *axis* information for the transport
to the user space, but in fact, their hardware representation is a
pressure-sesitive button. Same counts for potentiometers etc, which
aren't axis either. So maybe I should use some different layer for such
devices? MIDI legacy after all? I'm open to any suggestions :)
Thanks,
Daniel

Daniel,
The approach is pretty solid, with the exception that I do not think
we'd save much if we allocate every axis data separately (as I mentioned
in one of my earlier mails).
Coudl you please take a look at the following patches and let me know if
you see something wrong.
Thanks!

Input: add static inline accessors for ABS properties
From: Daniel Mack <[email protected]>
In preparation for dynamically allocated ABS axis, introduce a number of
sttaic inline access helpers. This should make the transition less
painful.

Input: switch to input_abs_*() access functions
From: Daniel Mack <[email protected]>
Change all call sites in drivers/input to not access the ABS axis
information directly anymore. Make them use the access helpers instead.
Also use input_set_abs_params() when possible.
Did some code refactoring as I was on it.

Input: dynamically allocate ABS information
From: Daniel Mack <[email protected]>
As all callers are now changed to only use the input_abs_*() access
helpers, switching over to dynamically allocated ABS information is
easy.

kmalloc and friends already print a warning with a stack dump when they
fail, unless this is overrided with __GFP_NOWARN, which is not the case
here. So in usually we do not print messages/warnigns when we fail to
allocate.

Hi Dmitry,
sorry for the late reply on this, I guess I haven't been much help
around here lately.

Agreed. We at least save the memory for all input devices that don't
have absolute axis at all.

I checked the patches and tried them locally on my desktop, and I can't
see any breakage, but we might need more coverage for testing.
Will you push them to the .36 merge window or is it too late for this?
Many thanks for your help :)
