Here we rather suffle source code into directories
preparing ground for future work.
Basically all this files movements should end up in the
following compel/ tree structure
compel/
├── arch
│ ├── aarch64
│ │ ├── plugins
│ │ │ └── std
│ │ └── src
│ │ └── lib
│ ├── arm
...
│ ├── ppc64
...
│ └── x86
...
This is architectural part, where each arch consists of
plugins/, and src/. src/ stands for code needed by compel
cli + lib
├── include
│ ├── compiler.h -> ../../criu/include/compiler.h
│ ├── elf32-types.h
│ ├── elf64-types.h
│ ├── int.h -> ../../criu/include/asm-generic/int.h
│ ├── piegen.h
│ ├── shmem.h
│ └── uapi
│ ├── compel.h
│ └── plugins.h
Common includes + uapi
├── plugins
│ ├── fds
│ ├── shmem
│ └── std
Plugins source code
└── src
├── lib
│ ├── handle-elf-32.c -> handle-elf.c
│ ├── handle-elf-32-host.c -> handle-elf-32.c
│ ├── handle-elf.c
│ └── handle-elf-host.c -> handle-elf.c
compel library
├── main.c
├── main-host.c -> main.c
compel cli
└── shared
└── fds.c
shared code between plugins and compel cli
Note: cross-compile won't work for a while.

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
A video tour on basic CRIU features
