libkrunfw is a library bundling a Linux kernel in a dynamic library \
|
|
in a way that can be easily consumed by libkrun. \
|
|
By having the kernel bundled in a dynamic library, libkrun can leave to \
|
|
the linker the work of mapping the sections into the process, and then \
|
|
directly inject those mappings into the guest without any kind of additional \
|
|
work nor processing.
