Hi,

kernel option GDB_REMOTE_CHAT allowed to share the same serial line
for console and remote gdb.

Looking at the following commit message for src/sys/conf/NOTES, it says
that GDB_REMOTE_CHAT has been removed, but it is not clear to me
how to obain the equivalent of that option. Could somebody explain?

Also, the man page for gdb(4) is outdated, since it contains references
to GDB_REMOTE_CHAT.

thanks
marco


Revision 1.1244, Sun Jul 11 01:44:07 2004 UTC (5 weeks, 4 days ago) by marcel
Branch: MAIN
Changes since 1.1243: +18 -25 lines
Diff to previous 1.1243 (colored)

Update for the KDB framework:
o  Rename WITNESS_DDB to WITNESS_KDB. In the new world order KDB is the
   acronym to use for debugging related code. The DDB option is used
   to enable the DDB debugger backend only.
o  Likewise, rename DDB_TRACE to KDB_TRACE, rename DDB_UNATTENDED to
   KDB_UNATTENDED and rename SC_HISTORY_DDBKEY to SC_HISTORY_KDBKEY.
o  Remove DDB_NOKLDSYM. The new DDB backend supports pre-linker symbol
   lookups as well as KLD symbol lookups at the same time.
o  Remove GDB_REMOTE_CHAT. The GDB protocol hacks to allow this are
   FreeBSD specific. At the same time, the GDB protocol has packets
   for console output.
