6.6 Process Image Analysis via the /proc Directory
In order to analyze the input and output data while the internal bus driver is
running, it is possible to view and to read out the process image of the relevant
modules via the /proc/driver/kbus/pab file. The start address
Byteoffset.Bitoffset of the individual process image is shown.
Example: cat /proc/driver/kbus/pab
