Currently I 'm writing a driver for a multi port serial
interface card on 2.0.0 as a module. The card interrupts only when data
is to be received or on detection of any changes in modem signals but
not when data needs to be transmitted :-( This would make it necessary
for a polling routine to be written which would tx data to the ports
which have data pending in their trasmit buffers. The driver supports 64
ports in total, i.e 4 cards of 16 ports each.
What would be the best way to hook up such a polling routine ?
Would it be alright to put it on to the tq_timer task queue, and
maintain it on the queue by the polling routine re-installing itself on
to the queue until signalled that the module is being unregistered. It
would also be necessary to disable interrupts for a while in such a
polling routine when tx is being done, would this be alright if
installed
on such a task queue ? Is there any other way of writing such a polling
routine ?
Thanx a lot in Advance ... happy hacking ...
Regards,
Sameer.
