>What is the cards error register logging ?
That is a very good question indeed. The problem is that card
issues an interrupt on SUCCESSFULL completion of a frame. Thus is
something goes bad - it just scips an interrupt. There is another
interrupt line, that indicates error, but it's not currently wired.
And from reading the documentation I'm not even sure it indicates
these types of errors (i.e.. FIFO overflow).
I can wire it if needed, there is one PCI controller IRQ input
available (not used now). On the other hand, I want to timestamp
everything tightly. I was wondering, which system call gets data
directly from 8053 timer under Linux?
