Hi all, I would like to monitor exactly when the kernel is writing to a certain I/O port. The device is a PCI device with some I/O mapped registers. They are written to/read from using outw, inw. Is there some debugging tool I can use to see all reads and writes? Thanks for your help, Duncan. -- Kernelnewbies: Help each other learn about the Linux kernel.
