I have developed some flight recording capability in the JUNOS FreeBSD based kernel, with the flight recorded data being captured in binary form for performance. All the subsequent formatting and display of this data is performed by a user-space application. I would like to reduce the amount of time that designers spend writing formatters to display their flight recorded data. kgdb is perfectly capable of displaying all kernel resident data structures, and the manner in which it does so is perfectly acceptable for flight recording purposes. The code that kgdb uses to support this framework is difficult to break out - does anyone know of a dwarf2 reader s/w implementation that is more re-usable? Ewart
