Detailed Description

High resolution device time, system time, and associated cycles counts.

Used to let the kernel driver read the current system time plus the associated high resolution time from a bus-level device as close as possible, and return the results to the caller which can then compute the time difference, taking into account the latencies determined from the cycles counts.

This structure also contains the card's status information (e.g. sync status).
