wistron_btns: x86_64 support for key mappings?

wistron_btns: x86_64 support for key mappings?

[Carlos Corbacho]

Would it be possible and acceptable to tweak the wistron_btns driver to be
at least partially useful to x86_64 users?

e.g. Strip out the BIOS calls on x86_64 and just leave the key mappings
(such as through ifdef's or whatever method is the best for this case).

(I would be happy to produce such a patch to do so, I just wanted some
thoughts first).

Well, the main concern is how woudl you detect button presses without
BIOS calls?

I see what you mean now - I had been looking at some of the other BIOS
calling functions in there at the top of the code which are not absolutely
necessary; but I see now stripping out all the BIOS calls is unavoidable
because of the polling required.

I suppose the only alternative then would probably be to port the code to
x86_64 assembly at some distant point in the future.

Sorry about the noise.
