J. Neuschäfer 79b51fedab remote_bitbang: Change sleep commands to Zz to avoid conflict with SWD
It was noticed that the remote_bitbang protocol has a design issue:
SWD and sleep commands cannot be implemented at the same time, because
they overlap:

 - SWD uses d,e,f,g for setting pin state
 - sleep uses d,D for microsecond and millisecond sleep, respectively

This has previously been reported by Marek Vrbka, but it wasn't fixed.

This commit does the following to resolve the issue:

 - Change the sleep commands to 'Z' for 1 ms, 'z' for 1 µs
 - Document 'D' and 'd' as deprecated aliases
 - Switch the remote_bitbang driver in OpenOCD to 'Z' and 'z'

Unfortunately that's a breaking change, because existing adapter-side
implementations of the protocol will have to implement the new commands
to keep working with future versions of OpenOCD. Fortunately, the
remote sleep commands haven't been part of an OpenOCD release yet,
which should limit the breakage somewhat.

Commit 290eac04b9 ("drivers/linuxgpiod: Migrate to adapter gpio

library libgpiod declares the line request flags:
	GPIOD_LINE_REQUEST_FLAG_BIAS_DISABLE
	GPIOD_LINE_REQUEST_FLAG_BIAS_PULL_UP
	GPIOD_LINE_REQUEST_FLAG_BIAS_PULL_DOWN
The names above are declared by the library inside an enum, thus
cannot be used by the C preprocessor in a #ifdef.

Determine in configure if the version of libgpiod provides the
line request flags for "bias" and define a C macro.
Use the new macro in the driver code.

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.

Antonio Borneo 1d076d6ce1 openocd: dump full command line in the debug log
When receiving an OpenOCD debug log to investigate about errors or
issues, the first question is often about providing the complete
command line to better understand the use context.
Plus, when OpenOCD is lunched by an IDE, its command line is kept
hidden inside the IDE, adding troubles to the user to recover it.

Add the full command line directly inside the debug log.

It could have been useful to also search and add in the log the
full path of the OpenOCD executable, but this is not an immediate
task due to portability among OS's. See, for example:
	https://stackoverflow.com/questions/933850
This part could be handled in a future change, if really needed.

Tomas Vanek 4c0a2cf42e target/adi_v5_swd: fix DP registers banking
ADIv6 brought more complicated rules for DP reg 0 banking.
Neither the original implementation [1] nor the later
modification [2] respected that the DP reg 0 is banked
for read only, not for write. Enforcing of an useless
SELECT write before a write to ABORT register may trigger
FAULT (CTRL/STAT bits ORUNDETECT and STICKYORUN are set)
or WAIT (DP is stalled by an outstanding previous operation)
and therefore make ABORT register virtually unusable
on some adapters (bitbang, CMSIS-DAP).

There are DP ABORT specific functions swd_queue_ap_abort()
and swd_clear_sticky_errors() which worked around the problem
using the lowest level swd->write_reg(). Using a specific
write procedure for a single DP register was error prone
(there are other DP_ABORT writes using swd_queue_dp_write_inner())
and also the Tcl command 'xx.dap dpreg 0 value' suffered
from unwanted SELECT write.

Other smaller discords in DP banking probably do not
influence normal DP operation however they may complicate
debugging in corner cases.

Adhere strictly to the DP banking rules for both ADI versions.

Antonio Borneo fcda9f1561 gdb_server: fix segfault with GDB command 'flash-erase'
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.

- probing chip is useless at all as the flash

Neither the text added in the commit message ("added ACK upon

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.

Causing the function returning a pointer past the end of the buffer and

N S c6e7e48b05 jtag/drivers: fix reset logic handling in OpenJTAG
The OpenJTAG driver behaviour always forces a system reset on jtag_init.
The driver was incorrectly assuming that when execute_reset is called
with trst set to 1 - perform a software TAP reset, otherwise perform a
system reset when trst is 0.

The set_state call assumes the that OpenJTAG hardware will perform a
software TLR reset if the target state is TAP_RESET. This is not the
case: the published VHDL will simply find the shortest path to TLR and
not perform a fixed 5 cycle operation with TMS held high.

Fix the code to only perform system resets when srst is 1 in
execute_reset and to force a software TAP reset operation in set_state
when the target state is TAP_RESET.

Parshintsev Anatoly 50be4bd267 jtag/mpsse: mpsse_flush should not treat LIBUSB_ERROR_INTERRUPTED as an error
LIBUSB_ERROR_INTERRUPTED can happen when (among other things) OpenOCD
process receives a signal like SIGHUP or SIGINT during a call to libusb.
Such situations are expected and should not be treated as an error - the
affected request should just be restarted.

Without this patch applied if a signal arrives during FTDI initialization
procedure we can easily end up (if JTAG speed is low) in situations like
https://review.openocd.org/c/openocd/+/4767. This happens because
fpsse_flush fails due to LIBUSB_ERROR_INTERRUPTED .

It should be noted that the current usage of mpsse_flush should be
revised since it seems that we don't always process error codes returned
by the function.

Tomas Vanek 226085065b target/cortex_m: drop useless target_halt() call
In 2008 the commit 1829361253 ("define resetting
the target into the halted or running state as an atomic operation.")
introduced the target_halt() call to the end of cortex_m3_assert_reset(),

Checkpatch-ignore: GIT_COMMIT_ID

A year later the commit ed36a8d15d
("... Updated halt handling for cortex_m3")
prevented cortex_m3_halt() take any action in case of TARGET_RESET state.
This narrowed the target_halt() called from cortex_m3_assert_reset()
to setting target->halt_issued and storing a time stamp.

Introducing ocd_process_reset(_inner) made the setting of halt_issued
and halt_issued_time useless. The Tcl function waits for halt
of all targets if applicable.

cortex_m_halt() and also target_halt() does not work as expected
if the cached target state is TARGET_RESET (although the core could
be out of reset and ready to be halted, just have not been polled).
Explicit Tcl arp_poll must be issued in many scenarios.

Remove the useless hack.

Also remove the explicit error return from cortex_m_halt_one()
in case of RESET_SRST_PULLS_TRST and asserted srst. If the communication

Tomas Vanek 3861699074 target/cortex_m: prevent asserting reset if examine is deferred
In a corner case when debug_ap is not available,
cortex_m_assert_reset() asserts reset to restore
communication with the target.

Prevent to do so on targets with defer_examine,
as such targets need some special handling to enable them
after reset anyway.

The change makes possible to handle a multicore Cortex-M SoC with
an auxiliary Cortex-M core(s) switched of by default
even with 'reset_config srst_gates_jtag'

Vincent Fazio 0d3d4c981a jtag/adapter: retype adapter_gpio_config.{gpio,chip}_num
Previously, the gpio_num and chip_num members of adapter_gpio_config
were typed as 'int' and a sentinel value of -1 was used to denote
unconfigured values.

Now, these members are typed as 'unsigned int' to better reflect their
expected value range.

The sentinel value now maps to UINT_MAX as all adapters either define an
upper bound for these members or, in the case of bcm2835gpio, only
operate on a specific chip, in which case the value doesn't matter.

Format specifiers have been left as %d since, when configured, valid
values are within the positive range of 'int'. This allows unconfigured
values to display as a more readable value of -1 instead of UINT_MAX.

Fixes:

- Data types of address & data parameters in riscv_batch_add_*()
  and riscv*_fill_dm*() changed to uint64_t and uint32_t.

- Corrected the comparison in riscv_batch_full().

- Corrected assertions in riscv_batch_get_dmi_read_op()
  and riscv_batch_get_dmi_read_data().

Cleanup:

- Simplified calloc() fail handling in riscv_batch_alloc().

- Added explicit NULL assignments in riscv_batch_alloc()
  for clarity and readability. Don't rely on calloc().

- Removed suffix `_u64` from riscv_*_fill_dm*() since it
  does not have any meaning.

- Renamed *dmi_write_u64_bits() to *get_dmi_scan_length()
  which better describes its purpose.

Antonio Borneo a47fae7934 helper/command: pass command arguments also as Jim_Obj
Some OpenOCD command gets fragment of TCL scripts as command-line
argument, fragments that will be kept and executed later on.
E.g. the command 'configure' gets the body of an OpenOCD event:
	$TARGET configure -event halted {TCL code}

These commands store the argument as a Jim_Obj and pass it to the
jimtcl interpreter when the TCL fragment has to be executed.
Using Jim_Obj as storage is relevant to let the jimtcl interpreter
to recover extra info of the TCL fragment, like the file-name and
the line-number that contain the fragment, that will be printed
out in case of run-time errors.

While converting the commands to COMMAND_HANDLER, we should avoid
storing the argument as C strings otherwise we will loose precious
info in case of run-time errors making challenging the debugging
of such TCL fragments.

Extend the struct command_invocation to contain the array that
points to the Jim_Obj of the command arguments.
This will be used while converting commands to COMMAND_HANDLER.

Commit e370e06b72 ("target: Deprecate 'array2mem' and

of commands mem2array and array2mem with TCL proc's that use
'read_memory' and 'write_memory'. It has left the deprecated code
of the target's version of the commands because the effort to code
the TCL replacement was not considered valuable.

To drop the last jim_handler commands, I consider much easier and
less error-prone to code them in TCL instead of converting the
deprecated code to COMMAND_HANDLER.

Drop the code in target.c and extend the TCL proc's.
While there, add the TCL procs to _telnet_autocomplete_skip.

arc_resume() should be able to advance over a potential breakpoint set
