OpenOCD can process certain requests from target software. Currently
@command{target_request debugmsgs}
are only supported for arm7_9 and cortex_m3.
is supported only for @option{arm7_9} and @option{cortex_m3} cores.
These messages are received as part of target polling, so
you need to have @command{poll on} active to receive them.
They are intrusive in that they will affect program execution
times. If that is a problem, @pxref{ARM Hardware Tracing}.
See @file{libdcc} in the contrib dir for more details.
In addition to sending strings, characters, and
arrays of various size integers from the target,
@file{libdcc} also exports a software trace point mechanism.
The target being debugged may
issue trace messages which include a 24-bit @dfn{trace point} number.
Trace point support includes two distinct mechanisms,
each supported by a command:
@itemize
@item @emph{History} ... A circular buffer of trace points
can be set up, and then displayed at any time.
This tracks where code has been, which can be invaluable in
finding out how some fault was triggered.
The buffer may overflow, since it collects records continuously.
It may be useful to use some of the 24 bits to represent a
particular event, and other bits to hold data.
@item @emph{Counting} ... An array of counters can be set up,
and then displayed at any time.
This can help establish code coverage and identify hot spots.
The array of counters is directly indexed by the trace point
number, so trace points with higher numbers are not counted.
@end itemize
See libdcc in the contrib dir for more details.
Linux-ARM kernels have a ``Kernel low-level debugging
via EmbeddedICE DCC channel'' option (CONFIG_DEBUG_ICEDCC,
depends on CONFIG_DEBUG_LL) which uses this mechanism to
deliver messages before a serial console can be activated.
This is not the same format used by @file{libdcc}.
Other software, such as the U-Boot boot loader, sometimes
does the same thing.
@deffn Command {target_request debugmsgs} [@option{enable}|@option{disable}|@option{charmsg}]
Displays current handling of target DCC message requests.
These messages may be sent to the debugger while the target is running.
The optional @option{enable} and @option{charmsg} parameters
both enable the messages, while @option{disable} disables them.
With @option{charmsg} the DCC words each contain one character,
as used by Linux with CONFIG_DEBUG_ICEDCC;
otherwise the libdcc format is used.
@end deffn
@deffn Command {trace history} (@option{clear}|count)
With no parameter, displays all the trace points that have triggered
in the order they triggered.
With the parameter @option{clear}, erases all current trace history records.
With a @var{count} parameter, allocates space for that many
history records.
@end deffn
@deffn Command {trace point} (@option{clear}|identifier)
With no parameter, displays all trace point identifiers and how many times
they have been triggered.
With the parameter @option{clear}, erases all current trace point counters.
With a numeric @var{identifier} parameter, creates a new a trace point counter
and associates it with that identifier.
@emph{Important:} The identifier and the trace point number
are not related except by this command.
These trace point numbers always start at zero (from server startup,
or after @command{trace point clear}) and count up from there.
