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.

Commit ea2e26f7d5 ("jtag: rewrite jim_jtag_configure() as

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
with the target is gated by any reset, cortex_m_write_debug_halt_mask()
fails. Propagate the error return of this call instead.

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.

- 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.

Antonio Borneo cdf89dcd2e helper/command: drop unused variables
In both functions script_debug() and script_command_args_alloc()
the variable len is never used, and Jim_GetString() does not
mandate it.

Drop the variable and pass NULL to Jim_GetString().

Antonio Borneo 88b8f2a796 target: drop deprecated code for mem2array and array2mem
Commit e370e06b72 ("target: Deprecate 'array2mem' and
'mem2array''") has already replaced the deprecated root versions
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.

Evgeniy Didin 74c9170b67 target/arc: skip over breakpoints in arc_resume()
When requested by the core code (handle_breakpoints = true),
arc_resume() should be able to advance over a potential breakpoint set
at the resume address instead of getting stuck in one place. This is
achieved by removing the breakpoint, executing one instruction,
resetting the breakpoint, then proceeding forward as normal.

With this patch applied, openocd is now able to resume from a
breakpoint halt when debugging ARCv2 targets via telnet.

This has previously been committed to the Zephyr project's openocd repo
(see https://github.com/zephyrproject-rtos/openocd/pull/31).

Evgeniy Didin 198b39ff45 target/arc: restore breakpoints in arc_resume()
Presently, we rely on gdb to restore break/watchpoints upon resuming
execution in arc_resume(). To match this behavior in absence of gdb
(more specifically, when handle_breakpoints is true), this patch
explicitly re-enables all breakpoints and watchpoints in arc_resume().

This has previously been committed to the Zephyr project's openocd repo

Daniel Anselmi 22b9c47468 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.

Use the result of the very first libusb_dev_mem_alloc() call to decide
if the underlining system supports dev mem allocation or we should
fall-back to plain heap malloc().

From the decision time on, keep using the selected type of memory allocator
and deallocator.

The function in question does not need to change target state. It is a
target-type-dependant function, however, IMHO, it is safe to assume that
any target type would not need to change type-independant state of a
target to figure out the arch.

There are quite a lot of "getters" in target interface.
They do not change target structure, nevertheless the structure is
passed to these functions via a plain pointer.

The intention is to clarify the purpouse of these functions by passing
the `target` structure as a pointer to constant data.
