12RTEMS/GDB host-target debugger is architectured around:
13
14@itemize @bullet
15@item One debugger, running on the host.
16@item One debug server, running on the target.
17@end itemize
18
19The host debugger communicates with the debug server using Sun RPC
20over UDP/IP (Ethernet).
21
22When opening a debugging session, the user takes the control over
23the entire target system. The target system is viewed as a single multi-threaded
24process.
25
26The debugger can observe the state of the system objects, without
27stopping the entire system. However, breakpoints and stepping affect (stop)
28the entire system.
29
30For a given target, only one single system debugging session is possible
31at a time.
