when i need to add a driver for any hardware that is not there by
default in linux box.
if the hardware company gives the driver or if i download it how will
i add to kernel.
I've to write a driver for a watchdog card, "Watchdog 1" by Quancom Electronic.
This card works as follows:
A specific address (or port or whatever...) must be written to repeatedly within
small time intervals (about 1 sec). If the watchdog doesn't get notified in time,
it will hard-reset the PC.
Has anyone done somthing like this?
Where would be a good point for doing the write operation? I'm thinking of the
schedule() function, or a timer.
The goal is that a server machine can be left unattended for weeks. The watchdog
should "detect" kernel failures, hangups etc. and reset the machine (assuming
that a hard reset will result in a working state automatically).
