[GDB] Zero-extend 16-bit segment registers

2008-06-30T18:19:48+00:00

When the 16-bit segment registers are accessed using 32-bit instructions the high order bytes are undefined on older CPUs. We now explicitly zero the high order bytes when snapshotting the CPU state. This ensures that the GDB stub reports consistent values for the segment registers.

[GDB] Remote debugging over UDP

2008-06-30T18:19:48+00:00

This commit implements GDB over UDP. Using UDP is more complex than serial and has required some restructuring. The GDB stub is now built using one or both of GDBSERIAL and GDBUDP config.h options. To enter the debugger, execute the gPXE shell command: gdbstub [...] Where is "serial" or "udp". For "udp", the name of a configured network device is required: gdbstub udp net0 The GDB stub listens on UDP port 43770 by default.

[GDB] Handle kill and detach packets.

This commit also includes a test to ensure that single stepping works, since continue, kill, detach, and single step all share code.
