openslx-ng/ipxe.git/src/core/gdbstub.c, branch v0.9.9 Fork of ipxe; additional commands and features https://git.openslx.org/openslx-ng/ipxe.git/atom/src/core/gdbstub.c?h=v0.9.9 2009-04-15T16:18:14+00:00 [gdb] Allow resynchronisation with gdb 2009-04-15T16:18:14+00:00 Stefan Hajnoczi 2009-04-15T16:16:31+00:00 urn:sha1:38a1d0fe3f92c74d848a8665d8d43392bc23bbfc This replaces the gdbstub's polite NAK behavior with retransmission of the current outstanding reply packet. It solves situations where gdb and gPXE's gdbstub get out of sync due to the lack of flow control in the gdb protocol spec. Signed-off-by: Michael Brown <mcb30@etherboot.org> [tables] Redefine methods for accessing linker tables 2009-03-13T02:06:30+00:00 Michael Brown 2009-03-12T19:41:40+00:00 urn:sha1:1266d7902bf7f2534ee279671d48613ef9b2434c Intel's C compiler (icc) chokes on the zero-length arrays that we currently use as part of the mechanism for accessing linker table entries. Abstract away the zero-length arrays, to make a port to icc easier. Introduce macros such as for_each_table_entry() to simplify the common case of iterating over all entries in a linker table. Represent table names as #defined string constants rather than unquoted literals; this avoids visual confusion between table names and C variable or type names, and also allows us to force a compilation error in the event of incorrect table names.

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 <transport> [<options>...] Where <transport> 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.
