Design Considerations

There are three logical groups of source files:

• The framework itself - not related to any specific kernel subsystem. It consists of two parts:

  • C-module - implements Python bindings to crash and GDB internals. The sources are in the Extension/ subdirectory.

  • Python API implemented on top of the C-module. The sources are in the pykdump/ subdirectory.

• A library of subroutines implementing access to different Linux kernel tables/structures, e.g. inet or storage. It consists of several modules residing in the LinuxDump/ subdirectory.

• Top-level programs - those that can be used for vmcore analysis without doing any programming. They reside in the progs/ subdirectory.
