Central Register Registry
Summary: Provide a new internal API for accessing register values
Currently there are a number of places that need to access guest register values including:
- -d cpu output
- hmp/qmp info registers
- gdbstub
and places that would like to access the register values like the TCG plugins sub-system.
Currently this is all handled by each individual front-end interfacing to the various sub-systems. It's time to bring that functionality under a single roof so front-ends just notify a central registry of how to access values and the central code can deal with interfacing with the other subsystems. Then quality of life improvements could be added like:
- customising the registers the -d cpu displays
- giving access to other registers in QMP/HMP
- de-duplicating the GDB XML generation for extra registers
- hooking in TCG plugins
