Description

drgn as a programmable debugger can be useful for kernel core analysis and may offer some advantages in some scenarios over crash, the standard tool used for this purpose.

Goals

1. Familiarization with drgn and it's capabilities and limitations
2. Investigate how it may be used to assist with kernel core analysis
3. Investigate how it may be used to create analysis tools (i.e. analyzevmcore) which can be used by someone without core analysis knowledge which may help expedite issue resolution
