StackOverflow https://stackoverflow.com/questions/1706700

Question

I want to record all read/write PCI transactions of a device driver. Is there a way to do it by a linux command or on software?

Was it helpful?

Solution

Memory-mapped I/O Trace is now in the mainline kernel, see /usr/src/linux/Documentation/trace/mmiotrace.txt for documentation.
