Tim Newsome db16b3dc5b Call poll at a fixed interval.
The existing implementation blocks in select() for a fixed amount of
time. This change tracks when the next event (likely poll()) wants to be
run, and uses a shorter timeout in select() if necessary.

Also track all these timeouts using milliseconds as returned by
timeval_ms() instead of `struct timeval` to simplify the code.

This feature is helpful if poll() wants to do something like sample PCs
or memory values for basically the entire time that otherwise OpenOCD
would be hung in select(). See
https://github.com/riscv/riscv-openocd/pull/541 for an example of that.
The RISC-V code using this change will be upstreamed some day, too.

Antonio Borneo c0c7d6fe8b openocd: fix Yoda conditions with checkpatch
The new checkpatch can automatically fix the code, but this
feature is still error prone and not complete.

Patch generated automatically through the new checkpatch with
flags "--types CONSTANT_COMPARISON --fix-inplace".

Some Yoda condition is detected by checkpatch but not fixed; it
will be fixed manually in a following commit.

Antonio Borneo 0a1f904707 openocd: remove NULL comparisons with checkpatch [2/2]
Patch generated automatically through a modified checkpatch that
detects the patterns
	if (NULL == symbol)
	if (NULL != symbol)
and through flags "--types COMPARISON_TO_NULL --fix-inplace".

The unmodified checkpatch detects this pattern as Yoda condition,
but it's odd fixing it as Yoda condition and then again as NULL
comparison. This triggered the modification to the script.

commands in jim by the root "word" only.

Register the full-name of the command and pass as private data the

Still use the tree of struct command to un-register the commands.

Some "native" commands (.jim_handler) share the same handler, then
the handler checks the command name to run the right code.
Now argv[0] returns the full-name of the command, so check the
name by looking in the struct command passed as private data.

Antonio Borneo 4289389937 helper/command: override target only on target prefixed cmds
In current code the current target is overridden whenever
jim_handler_data is not NULL. This happens not only with target
prefixed commands, but also with cti, dap and swo/tpiu prefixed
commands.
While this is not causing any run-time issue, by now, the
behaviour is tricky and makes the code cryptic.

Add a specific field to struct command for the target override so
the content of jim_handler_data can be restricted to command
specific data only (today only cti, dap and swo/tpiu).

Extend the API register_commands() to specify the presence of
either the command data or the override target.

The new API makes obsolete calling command_set_handler_data() to
set jim_handler_data, so remove it.

Antonio Borneo a510c8e23c helper/command: always pass struct command as jim private data
While registering a new command, jim accepts a pointer to command's
private data that will be accessible during the command execution.

Today openocd is not consistent and passes different private data
depending on the command, and then even overwrites it:
- "simple" commands (.handler) are registered with their own
  struct command pointer as command private data;
- "native" commands (.jim_handler) at root level are registered
  with NULL command private data;
- "native" commands (.jim_handler) not at root level are
  registered with the struct command pointer of their root command
  as command private data but, when executed, the command private
  data is overwritten by the value in field jim_handler_data taken
  from their struct command.

Uniform the usage of command private data by always set it to the
struct command pointer while registering the new commands.
Note: for multi-word commands only the root command is registered,
so command private data will be set to the struct command of the
root command. This will change later in this series when the full-
name of the command will be registered.

Don't overwrite the command private data, but let the commands that
needs jim_handler_data to get it directly through struct command.

For sake of uniformity, let function command_set_handler_data() to
set the field jim_handler_data also for "group" commands, even if
such value will not be used.

Now Jim_CmdPrivData() always returns a struct command pointer, so
wrap it in the inline function jim_to_command() to gain compile
time check on the returned type.
While there, uniform the code to use the macro Jim_CmdPrivData()
to access the command's private data pointer.

Antonio Borneo 23d8831391 target: avoid polling during 'resumed' event handler
OpenOCD is based on a single main loop that schedules all the
activities.
At the execution of a TCL command, the timestamp is checked to
eventually trigger the polling of the targets. This means that by
executing a TCL command the polling can be triggered and detect a
change of target's state.

When openocd 'resumes' a target, the target can halt again by
hitting a breakpoint.
The 'resumed' event handler is started just after the target has
been resumed, but it triggers a polling before the execution of
its very first instruction.
If the polling finds the target halted, it will run the 'halted'
event handler, that will then be executed 'before' the pending
'resumed' handler.

In case of gdb, a 'continue' command will restart the target but,
polling (and halt detection) executed before the end of the resume
process will hide the halt. As a consequence, the gdb will not be
informed of the halt and will remains waiting as if the target is
still running without showing the prompt.

This can be verified by running on the target a firmware with a
loop, run openocd with a dummy 'resumed' event, and let gdb to set
a breakpoint in the loop. A 'continue' command will cause the
target to halt again by hitting the breakpoint at the next loop
iteration, but gdb will loose it and will not return the prompt.

	openocd -f board/st_nucleo_f4.cfg -c \
		'stm32f4x.cpu configure -event resumed {echo hello}'
	arm-none-eabi-gdb -ex 'target remote :3333' -ex 'b *$pc' -ex c

Disable the polling while executing target's resume().
Document it and provide hints to developers to cope with future
implementation.

specific, cf. included cfg files. The driver infers most parameters from
current setting in CR, CCR, ... registers.

Antonio Borneo e2e8a5f467 gdb_server: allow multiple GDB connections to selected targets
The default way of working is to have a single GDB attached to one
target, so OpenOCD accepts only one connection to the GDB port of
each targets and rejects any further connection.

There are some barely safe use cases in which it could get useful
having a second GDB connection to the same target.
One such use case is while using GDB as a 'non-intrusive memory
inspector', as explained in the OpenOCD documentation.
One GDB can be left running an infinite loop to dump some memory
area, or even analysing the content, while keeping a second GDB
ready for user interaction or spot memory check.

Add a target configure option to specify the maximum number of GDB
connections allowed for that target, keeping the default to 1.

Christopher Head d3aa2d3536 target/cortex_m: reduce duplication in profiling
The Cortex-M implementation of profiling contains a bunch of
conditionals and checks to handle both chips which have PCSR and chips
which do not. However, the net effect of the non-PCSR branches is
actually exactly the same as what target_profiling_default does. Rather
than duplicating this code, just detect the situation where PCSR isn’t
available and delegate to target_profiling_default.

Christopher Head a7502ee8b9 target: allow profiling from running
There are a handful of implementations of profiling. There is the
default implementation, which repeatedly halts and resumes the target,
sampling PC each time. There is the Cortex-M implementation, which
uses PCSR if available, otherwise falling back to halting and resuming
and sampling PC. There is the OR1K implementation, which reads NPC
repeatedly. Finally, there is the NDS32 implementation which uses some
kind of AICE commands with which I am unfamiliar.

None of these (with the possible exception of the NDS32
implementation) actually require the target to be halted when starting
profiling. The Cortex-M and OR1K actually resume the target as pretty
much their first action. The default implementation doesn’t do this,
but is written in such a way that the target just flips back and forth
between halted and running, and the code will do the right thing from
either initial state. The NDS32 implementation I don’t know about.

As such, for everything except NDS32, it is not really necessary that
the target be halted to start profiling. For the non-PCSR Cortex-M and
default implementations, there is no real harm in such a requirement,
because profiling is intrusive anyway, but there is no benefit. For
the PCSR-based Cortex-M and the OR1K, requiring that the target is
halted is annoying because it makes profiling more intrusive.

Remove the must-be-halted check from the target_profiling function.
Add it to the NDS32 implementation because I am not sure if that will
break when invoked with a running target. Do not add it to any of the
other implementations because they don’t need it.

Antonio Borneo 7c88e76a76 target: do not print an error on shutdown in target events
Before commit b3ce5a0ae5 ("target: use LOG_USER to print errors
in events") an error in an event handler was silently lost, while
now the associated message is printed out.

A "shutdown" command in a target event (e.g. in gdb-detach) causes
the event to end with error code ERROR_COMMAND_CLOSE_CONNECTION,
that triggers the error message:
	shutdown command invoked
	Error executing event <event-name> on target <target-name>:

The error code returned by the command "shutdown" is required to
stop the execution in a script/proc and avoid executing any
further command in the script/proc.
It is then normal to get an error code from the "shutdown" command
and it should not be printed out.

Intercept the return code of the event in case of "shutdown", then
skip scheduling other target events and return without printing
the incorrect error message.
