Plugin: rehosting

Summary

The rehosting plugin is intended to make it easier to get a custom architecture up and running by allowing one to load an arbitrary file (e.g. a raw firmware image) into memory and execute it. This can be slightly simpler than having to modify QEMU's loader, which is somewhat specialized for ELF executables and Linux.

Arguments

  • kernel: string, no default. The filename that should be loaded into memory.
  • base: ulong, no default. Where in guest memory (physical address) the file should be loaded.
  • entry: ulong, no default. The entry point (physical address) where execution should begin.

Dependencies

None.

APIs and Callbacks

None.

Example

To load a kernel named foo.bin at 0x10000 and begin execution at 0x10100:

$PANDA_PATH/x86_64-softmmu/qemu-system-x86_64 -replay foo \
    -panda rehosting:kernel=foo.bin,base=0x10000,entry=0x10100

Bugs

Currently only supports 32-bit x86.
