Re: [PATCH v3] input/keyboard: new OpenCores Keyboard Controller driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

It has a bit long since last time I touched the driver, so I should also try to refresh my memory about it :). I suppose that you're right in the double allocation issue (I took another keyboard driver as a starting point and probably the double allocation was already there...), so feel free to introduce the change and I will test it as soon as I can.

About the exact scancode - key mapping, the reason is that since the FPGA opencores device already implements a translation table, I found that another translation table sounded a bit redundant.

Best regards,

Javier

Why do we allocate keycode table separately form the main structure?

the double alloc looked a little funny, but i didnt dive deep into the
details.  but as you point this out, it seems to make sense to me.
any problems with that change Javier ?

i.e. we do:
struct ... { ... unsigned short keycode[NUM_KEYS]; }
rather than doing two calls to kmalloc

I think I still have some reservations with the notion that we can just
have exact "scancode" - KEY_* mapping and hardware producers will adjust
the hardware to follow the deriver but I guess it's OK...

considering this is a piece of "hardware" implemented in FPGAs, i
think it's ok too.  if someone really needs more flexibility, then
they're free to extend the driver and submit a patch :).
