Marc Schink ad21613618 server/telnet: Restructure commands
Use a command group 'telnet' with subcommands instead of individual
commands with 'telnet_' prefix. Even though there is only one subcommand
at the moment, make this change to ensure consistency with other commands.

The old command is still available to ensure backwards compatibility,
but are marked as deprecated.

Antonio Borneo 71013521d7 server: gdb: respect command gdb_report_register_access_error
Commit 236c54c94a ("server/gdb_server.c: support unavailable
registers") correctly returns a string of 'x' when the register is
not available in the current target.

While implementing this, it incorrectly drops the pre-existing
feature of optionally ignoring errors while reading a register.
This feature has a real use case documented in the OpenOCD manual
in chapter 'Using GDB as a non-intrusive memory inspector', where
GDB attaches to a target without halting it. For targets that need
to be halted to read its registers, we need to hack the values of
the registers returned to GDB; either returning 'xxxx' or an error
causes GDB to drop the connection.

Re-add the check on 'gdb_report_register_access_error' to keep the
pre-existing behavior when a register error has to be ignored:
- return a string of '0';
- drop a debug message.

Antonio Borneo 35e4c4616f gdb_server: drop useless check in gdb_keep_client_alive()
OpenOCD can send it's log to gdb, and gdb replies with 'OK'.
Calls to LOG_XXX() are also present in the code that communicates
with gdb. This can cause infinite nested calls.

OpenOCD uses the flag 'gdb_con->busy' to protect the communication
with gdb and prevent nested calls.

There is no reason to check for 'gdb_con->busy' in the code for
keep-alive, as keep_alive() is never called in this gdb server;
the flag would eventually be set if the current keep_alive() will
send something to gdb.

Drop the flag 'gdb_con->busy' in gdb_keep_client_alive().
While there, document the use of 'gdb_con->busy'.

Antonio Borneo 0c0243228c gdb_server: add async-notif keep-alive during memory read/write
To avoid gdb to timeout, OpenOCD implements a keep-alive mechanism
that consists in sending periodically to gdb empty strings embedded
in the "O" remote reply packet.

The main purpose of "O" packets is to forward in the gdb console
the output of the remote execution; the gdb-remote puts in the "O"
packet the string that gdb will print. It's use is restricted to
few "running/execution" contexts listed in
http://sourceware.org/gdb/onlinedocs/gdb/Stop-Reply-Packets.html
and this currently limits the keep-alive capabilities of OpenOCD.

Long data transfer (memory R/W) can also cause gdb to timeout if
the interface is too slow. In this case the usual keep-alive based
on "O" packet cannot be used and, if used, would trigger a protocol
error that causes the transfer to be dropped.
The slow transfer rate can be simulated by adding some delay in the
main loop of mem_ap_write() and mem_ap_read(), then using the gdb
commands "dump" and "restore".

In the wait loop during a memory R/W, gdb drops any extra character
received from the gdb-remote that is not recognized as a valid
reply to the memory command. Every dropped character re-initializes
the timeout counter and could be used as keep-alive.

From gdb 7.0 (released 2009-10-06), an asynchronous notification
can also be received from gdb-remote during a memory R/W and has
the effect to reset the timeout counter, thus can be used as
keep-alive.
The notification would be treated as "junk" extra characters by any
gdb older than 7.0, being still valid as keep-alive.
Check putpkt_binary() and getpkt_sane() in gdb commit
74531fed1f2d662debc2c209b8b3faddceb55960

Currently, only one notification packet ("Stop") is recognized by
gdb, and gdb documentation reports that notification packets that
are not recognized should be silently dropped.
Use 'set debug remote 1' in gdb to dump the received notifications
and the junk extra characters.

Add a new level in enum gdb_output_flag for using the asynchronous
notifications.
Activate this new level during memory transfers.
Send a custom "oocd_keepalive" notification packet as keep_alive.
While there, drop a useless return in the switch/case, already
managed in case of break.

After this commit, the proper calls to keep_alive() have to be
added in the loops that code the memory transfers. Of course, the
keep_alive() should be placed during the wait for JTAG flush, not
while locally queuing the JTAG elementary transfers.

Running the GDB command 'flash-erase' triggers sending the remote
GDB commands 'vFlashErase' (one per flash bank) followed by one
single 'vFlashDone', with no 'vFlashWrite' commands in between.
This causes the field 'gdb_connection->vflash_image' to be NULL
during the execution of 'vFlashDone', triggering a segmentation
fault in OpenOCD.

While parsing 'vFlashDone', check if any image to flash has been
received.

On 2008-03-05, before git's age, commit 6d95014674 adds sending

remote command that requires to be ACK'ed.

Neither the text added in the commit message ("added ACK upon
connection (send +)") nor in the associated comment ("send ACK to
GDB for debug request") provide an exhaustive explanation for
sending this unsolicited ACK.

This code has never been touched since its introduction.

Analysis of GDB code doesn't show it's required, including old GDB
code.
Running gdbserver (from GDB package) and attaching it with "nc"
shows that gdbserver does not send any ACK to a new connection.
Same for lldb-server.

Drop it!

Daniel Anselmi d2b2ac28d9 ipdbg: improve ipdbg-host speed
By queuing multiple jtag transfers the connection speed between
JTAG-Host and JTAG-Hub is improved. This is due to much less
calls to OS functions. An improvement of about x30 has been
measured with ftdi-based jtag adapters

For this to work the JTAG-Host server needs to know if flow control
is enabled on the JTAG-Hub ports. This is possible with newer
JTAG-Hub/JtagCDC. For old JTAG-Hubs the queuing is not enabled so
this change is backwards compatible.

Antonio Borneo 382148e4dd openocd: fix SPDX tag format for files .c
With the old checkpatch we cannot use the correct format for the
SPDX tags in the file .c, in fact the C99 comments are not allowed
and we had to use the block comment.

With the new checkpatch, let's switch to the correct SPDX format.

Antonio Borneo cc75aa37c5 openocd: add post-init and pre-shutdown helpers
It is a common requirement to automatically execute some command
after "init".
This can be achieved, either in scripts or through OpenOCD command
line, by explicitly calling "init" followed by the commands.
But this approach fails if the request for post-init commands is
spread across configuration files; only one of the files can split
pre-init and post-init status by calling "init".
The common workaround is to "rename" the command "init" and
replace it with a TCL proc that calls the original "init" and the
post-init commands. E.g. in Zephyr script [1].

To simplify and formalize the post-init execution, use a TCL list
that contains the list of commands to be executed. Every script
can contribute adding new commands, e.g. using "lappend".

In the same way, formalize the pre-shutdown execution with a TCL
list of user commands to be executed before OpenOCD exit.

Document them and add trivial examples.

Drop from documentation the suggestion to rename "shutdown".

Copy from the code in command_run_line() the proper setup before
executing Jim_EvalObj().

Antonio Borneo b4f8d99c8d smp: deprecate legacy SMP core switching support
The deprecation was already in the documentation since v0.11.0
through commit 85ba2dc4c6 ("rtos/hwthread: add hardware-thread
pseudo rtos") but OpenOCD was not informing the user printing a
runtime message.

Remove the deprecated method from the documentation and print a
deprecated message at runtime.
There is no reliable way to print the same message in GDB console,
so we have to rely on user noticing it in the OpenOCD log.
Target is to remove the functionality after v0.12.0.

Antonio Borneo 5ebb1bdea1 server/gdb: fix return of gdb remote monitor command
Current implementation for gdb remote monitor command uses the
command_run_line() to execute the command.
While command_run_line() has several advantages, it unfortunately
hides the error codes and outputs the result of the command
through LOG_USER(), which is not what gdb requires. See 'qRcmd' in
https://sourceware.org/gdb/onlinedocs/gdb/General-Query-Packets.html

Replace command_run_line() with Jim_EvalObj() and parse the output
to provide the proper result to gdb.

Can be tested by defining in OpenOCD:
	proc a {} {return hello}
	proc b {} {return -code 4}
	proc c {} {return -code 4 "This is an error!"}
then by executing in gdb console:
	monitor a
	monitor b
	monitor c
	monitor foo

- Do not print zero-length incoming packets (this occurred
