9.3 I/O Logging

This is a generic feature available on all devices for logging slave accesses (i.e. accesses responded to by this device). Several categories of generic I/O logging are available. Logging is performed to the I/O loggers (see Section 9.1, "Message Log", on page 141) of names similar to the device you are enabling the logging for.

Caveat: Currently, devices which route to other devices may appear as if they are responding to the messages themselves, so bridge devices will likely log everything that is behind them.

Log PCI Config Space Accesses

Checking this will log PCI Config Space accesses made to the device.

Log I/O Space Accesses

Checking this will log I/O Space accesses made to the device. These are the accesses made with the x86 IO read/write instructions.

Disable Fastpath I/O when Logging

This item, checked by default, disables the Fastpath I/O mechanism when I/O Space Accesses logging is enabled. If this is unchecked, accesses may not appear in the log.

Log Memory Space Accesses

Checking this will log Memory Space accesses made to the device. These are the accesses corresponding to standard x86 move, read and write instructions to memory.
