Hi,
I've recently started working on a Fast IrDA driver for the StrongARM
1100/1110
CPUs (specifically Compaq's iPAQ). While reading the code in
drivers/net/sa1100_ir.c
I stumbled across a few things I'd like to know - perhaps s.o. on this
list
can help me here:
- in sa1100_irda_set_speed there is a case statement that should
(basically) select
SIR or FIR operation based on the baudrate passed as a parameter. This
function
is called from several places in the driver (suspend, resume etc.).
What interests
me is the sa1100_irda_ioctl function which should be the right place
to
control switching between SIR and FIR operation.
Currently, sa1100_irda_set_speed always receives 9600 as speed
parameter. Is
there a way to access the ioctl from user mode (i.e. which device is
associated
when I'm not using irattach to bind IrDA to a serial port) ?
- Do you think it generally makes sense to integrate a SIR and FIR
driver in one
kernel module ? Autosensing for speed is not supported anyway AFAIK
and there's
not too much code in comon between the two drivers.
