Hi,
I wanted to see if a driver for the watchdog timer built into the
Winsystems EPX-C3 SBC board is something the linux kernel people are
interested in. If so, how should I structure the driver if I were to
submit it?
The reason I ask is that this board's watchdog is pretty basic/primitive.
It is not a PCI device, it doesn't have any status registers per se and is
configured by jumpers on the board only.
Behavior of the watchdog (if configured):
Enable the watchdog: Write a 1 to io address: 0x1EE
Pet the watchdog before the timeout period (1.5s or 200s depending on
jumper config): Write any value to io address: 0x1EF
Disable the watchdog: Write a 0 to io address: 0x1EE.
Pretty basic huh? As such -- there is no way to tell in software if the
watchdog exists, if it is enabled, or how long the timeout is. Since this
is so basic.. does it belong in the mainline kernel? Or should it best be
done as a userspace program instead?
Any guidance is appreciated..
