Antonio Borneo 62686ab161 armv4_5: fix output of command 'arm reg'
Commit fc2abe63fd ("armv7m: use generic arm::core_mode") adds
two special modes for ARMv6M and ARMv7M in struct arm_mode_data[].
While these modes do not have any additional register to be dumped
by command 'arm reg', the command still prints an header for these
modes but not followed by any register.

Detect the special modes for ARMv6M and ARMv7M and skip them to
avoid printing the useless header.

Antonio Borneo 693b8501e5 armv4_5: fix segmentation fault in command 'arm reg'
Commit fed7131049 ("armv4_5: support weirdo ARMv6 secure monitor
mode") introduces the secure mode 28 of ARMv6 as a synonymous of
mode 22 (MON), but does not add it in the switch/case in command
'arm reg'.
When command 'arm reg' scans the array arm_mode_data[] on targets
without secure modes, it does not detect the new secure mode as
not supported by the architecture, thus triggers a segmentation
fault when it try to read the register's value from unallocated
memory.
Issue detected with target arm926ejs.

Add the new mode in the switch/case and treat it as the mode MON.

Marc Schink 7b641d3d4e Add initial RTT support
Real Time Transfer (RTT) is an interface specified by SEGGER based on
basic memory reads and writes to transfer data bidirectionally between
target and host.
Every target that supports so called "background memory access", which
means that the target memory can be accessed by the debugger while the
target is running, can be used.

RTT is especially of interest for targets which do not support Serial
Wire Output (SWO) (e.g. ARM Cortex-M0) or where using semihosting is
not possible (e.g. real-time applications) [1].

The data transfer is organized in channels where each channel consists
of an up- and/or down-channel. See [2] for more details.

Channels are exposed via TCP connections. One or more RTT server can be
assigned to each channel to make them accessible to an unlimited number
of TCP connections.

The current implementation does not respect buffer flags which are used
to determine what happens when writing to a full buffer.

Note that the implementation is designed in a way that the RTT
operations can be directly performed by an adapter (e.g. J-Link).

Tomas Vanek d459a2d27d adi_v5_swd: wait for readable DPIDR, ABORT if stalled
Reading of DPIDR is the very first operation after JTAG to SWD sequence.
Without this change if DPIDR read fails then swd connect fails.

Keep trying JTAG to SWD sequence and DPIDR read until success
or timeout 0.5 sec. It makes setting of adapter srst delay on SWD transport
mostly unnecessary.

Also test for ERROR_WAIT (which should not occur according to
IHI 0031E B4.3.2 but a quirk is known) and if bus is kept stalled
then issue abort to make the next connect possible.

Tomas Vanek 646c3c9902 arm_adi_v5: prevent possibly endless recursion in dap_dp_init()
If dap_dp_read_atomic() in 30 trials loop fails, dap->do_reconnect is set.
Following dap_dp_read_atomic() calls dap_queue_dp_read() which in case
of SWD transport calls swd_queue_dp_read(). It starts
with swd_check_reconnect() and it calls swd_connect() because
dap->do_reconnect is set. swd_connect() does some initialization,
reads DPIDR and calls dap_dp_init() again!

Moreover if dap_dp_init() is called from cortex_m_reset_(de)assert()
one level of recursion is necessary to reconnect the target.

Introduce dap_dp_init_or_reconnect() for use in cortex_m reset
and similar.
Remove loop of 30 atomic reads of DP_STAT to prevent unwanted recursion.

Tomas Vanek f32ca2d25d target/cortex_m: remove wrong xPSR.ICI/IT bits handling
If a Cortex-M (not M0, M0+) target was stopped in the middle of
a conditional IT block or in the load/store multiple instruction,
cortex_m_debug_entry() used wrong xPSR bits to detect it and then
cleared 8 bits of the exception number from xPSR
- probably wrong bit mask again.

I believe clearing of the ICI/IT bits in cortex_m_debug_entry() has no
reason as Cortex-M does not use instruction injecting.

Remove the wrong code.

The change was originally a part of http://openocd.zylin.com/4862
It is now re-submitted as #4862 is not ready.

Requirements:
GPIOs must be initialized appropriately, and SPI flash chip be configured

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

(via the internal mode), OpenOCD can collect the trace buffers then append
it to a specified file or named pipe and propagate the trace to 'tcl_trace'

This change is allowing OpenOCD to stream the captured trace over TCP.

When using this configuration OpenOCD acts like a server and multiple
clients can connect and receive the captured trace.

Example on STM32F7 running at 216MHz:
  itm port 0 on
  tpiu config internal :3344 uart off 216000000

possibly, we could get the service from a connection but this is possible

also, storing one of the connections in new_connection_handler_t and get

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

Christopher Head d05ef53cbd target: restore last run state after profiling
Now that it’s possible to start profiling from either a running or a
halted state, rather than unconditionally halting after profiling
finishes, it makes more sense to restore the processor to whatever state
(running or halted) it was in before profiling started.

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.

These are all the changes from https://github.com/riscv/riscv-openocd
(approximately 91dc0c0c) made just to src/target/riscv/*. Some of the
new code is disabled because it requires some other target-independent
changes which I didn't want to include here.

Built like this, OpenOCD passes:
* All single-RV32 tests against spike.
* All single-RV64 tests against spike.
* Enough HiFive1 tests. (I suspect the failures are due to the test
suite rotting.)
* Many dual-RV32 (-rtos hwthread) against spike.
* Many dual-RV64 (-rtos hwthread) against spike.

I suspect this is an overall improvement compared to what's in mainline
right now, and it gets me a lot closer to getting all the riscv-openocd
work upstreamed.

This is tricky in case of aarch64, where the private data are in a

While the current solution is working fine, it's not clean and

Override 'target->private_config' to the correct pointer while
calling adiv5_jim_configure().

This fix is proposed separately because is not tested on a correct
target device, but tested on SPEAr320 by hacking the target type
and pretending it is the correct one, e.g.:
	sed -i s/arm926ejs/arm920t/ tcl/target/spear3xx.cfg

The memory leaks detected and fixed are:
- arm register cache;
- EmbeddedICE register cache;
- arm_jtag_reset_callback internal data;
- struct <target_type>_common.

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.

Antonio Borneo 6f88aa0fb3 target/cortex_a: fix memory leak of register cache
There is no method to free the register cache, allocated in
armv4_5, so we get a memory leak.
Issue identified by valgrind.

Implement the method arm_free_reg_cache() and call it in cortex_a
deinit and to exit for error during arm_dpm_setup().
Tested on dual cortex-A stm32mp15x.
This change is inspired from similar fix in commit b01b5fe13a
("armv7m: Fix memory leak in register caching.").

The same allocation is also used by target types "arm7tdmi",
"arm9tdmi", "arm11" and "xscale" but they all lack the deinit
method and I do not have relevant HW to test the fix. For such
reasons they are not addressed in this patch.

Antonio Borneo 37330f89d7 target/cortex-m: enable C_DEBUGEN during examine
Current code for Cortex M does not set C_DEBUGEN as soon as
possible, (which means during target examine), but later-on either:
1) at command 'halt' (e.g. for 'gdb-attach' event);
2) at command 'soft_reset_halt';
3) at commands 'reset', 'reset halt' or 'reset init';
4) during polling, but only if the target:
    = enter in 'double fault', or
    = exit from a reset, or
    = halts (not possible if C_DEBUGEN is not set)

Plus, if commands in 1) or 2) are executed before the very first
poll of the target, the value of 'cortex_m->dcb_dhcsr' is used not
initialized while writing it back in DCB_DHCSR.

Another side effect of this situation is that it's possible to set
a HW breakpoint with the target running, while C_DEBUGEN is not
set. Accordingly to [1], C1.3.1 "Debug authentication":
    When DGBEN is LOW and DHCSR.S_HALT == 0:
    ...
    FPB breakpoints do not generate an entry to Debug state and,
    if no DebugMonitor exception is generated, will escalate to
    HardFault, Lockup, or be ignored.
On STM32MP15x I get HW breakpoint ignored, while on STM32F411 I
get HardFault.
E.g. following these steps:
- power-on a pre-flashed board that starts running the firmware;
- connect openocd, without halting or resetting the board;
- set a HW breakpoint to some address often executed;
- wait, but the board doesn't halt ...;
- type the command 'halt';
- if the Cortex-M has HardFault it would be visible and the fault
  is at the breakpoint address;
- if no HardFault then type the command 'resume';
- wait and the board will finally halt at the HW breakpoint.

A similar issue has been detected on Cortex-A code and fixed by
commit bff87a7f28 ("target/cortex_a: enable DSCR_HALT_DBG_MODE
during examine").
Follow the same approach and set C_DEBUGEN during examine.
Also, initialize 'cortex_m->dcb_dhcsr' during examine.

Antonio Borneo ac18e960ce swim: abstract the transport in stm8 target
SWIM is implemented by (ab)using the HLA API. This was acceptable
when OpenOCD code did not provided a clear separation between
transports and related APIs. Still today SWIM in OpenOCD is only
supported by STLink, so the decision to re-use the HLA API was the
simpler way to implement it.
After commit efd1d64222 ("adapter: switch from struct
jtag_interface to adapter_driver") the transports API are better
split and SWIM can be implemented as a separate set of API. This
would open the possibility to extend OpenOCD for other adapters
that provide SWIM, e.g. versaloon, or through SPI emulation [1].

Introduce a new set of files swim.[ch] to handle the SWIM API.
Beside the API that almost match the transport low-level data
communication (system_reset, read_mem, write_mem), add a further
API reconnect. Today, inside HLA STLink code, the reconnect is
implemented by hacking the HLA API state(). Please notice that
due to this hack the return type is incorrect; stlink_usb_state()
returns ERROR_OK in SWIM mode, while its return type is enum
target_state. Ignore the type mismatch and still call the HLA API
state in the new SWIM API reconnect. Further commit will fix it.

The script checkpatch available in new Linux kernel offers an

Antonio Borneo 9b29cb58ac coding style: remove useless break after a goto or return
In a switch/case statement, a break placed after a goto or return
is never executed.
The script checkpatch available in Linux kernel v5.1 issues a
warning for such unused break statements.
In the process of reviewing the new checkpatch for its inclusion
in OpenOCD, let's get rid of these warnings.

The script checkpatch is unable to fixup automatically this case.
Thanks to having "break" command using a single code line, this
patch has been generated using the script below:

	find src/ -type f -exec ./tools/scripts/checkpatch.pl -q \

Nevertheless it is still extremely useful with multicore chips
where it allows to reset only one of the cores, option not
available through asserting the chip-wide srst.
It also get useful to handle the reset on some problematic chip,
as in http://openocd.zylin.com/5489

Antonio Borneo 4873503ae4 cortex_a: don't wait for target halted in deassert_reset()
The tcl script src/target/startup.tcl has already the proper
centralized support to wait for all targets to halt after the
command "reset halt". The extra wait in cortex_a_deassert_reset()
is not required.
This extra wait is also an issue for multi-core support, because
waiting for one core to halt can delay the halt request to the
other cores.

Replace the indirect call to cortex_a_halt(), that embeds the wait
for halt, with a low-level halt sequence.

The on-going work on the reset framework is compatible with this
change; in fact it keeps in startup.tcl the wait for targets to
halt, even if current code proposal for cortex_a simply removes
the function cortex_a_deassert_reset().

Matthias Welwarsky afe899f938 cortex_a: warn on broken debug_base setting
A common problem with target configurations appears to be broken
debug base address configuration. ARM DDI0406C.d specifies in App. D,
1.4.1, that bit 31 of the debug base address serves as identification
of an external debugger, as opposed to an internal access to memory
mapped debug registers by the CPU. External accesses are treated
as privileged and require no debug authentification via the lock
access register.

Sometimes the base address of a debug component is wrong even
in the targets' ROM table. In this case, the correct base address
must be specified using the -dbgbase argument when creating the
target.

This patch adds a warning when bit 31 of the debug base address
is not set, as a hint to the user.

      - If the PE is in AArch64 state, this is an A64 instruction.
      - If the PE is in AArch32 state, this is a T32 instruction

But in armv8_opcodes specifically in t32_opcodes we were using some
A32 instructions for HLT, LDRx and STRx opcodes.

Using the correct LDRx and STRx opcodes, fixes 16 and 8 bits memory access
when the PE is in AArch32 state.

Tarek BOCHKATI a154973896 target/aarch64: fix soft breakpoint when PE is in AArch32 state
Before this patch aarch64_set_breakpoint was using either A64, or A32
HLT opcode by relying on armv8_opcode helper.
This behaviors ignores the fact that in AArch32 state the core could
execute Thumb-2 instructions, and gdb could request to insert a soft
bkpt in a Thumb-2 code chunk.

In this change, we check the core_state and bkpt length to know the
correct opcode to use.

Note: based on https://sourceware.org/gdb/current/onlinedocs/gdb/ARM-Breakpoint-Kinds.html
      if bkpt length/kind == 3, we should replace a 32-bit Thumb-2 opcode,
      then we use twice the 16 bits Thumb-2 bkpt opcode and we fix-up the
      length to 4 bytes, in order to set correctly the bpkt.

Antonio Borneo e7306d361b coding style: fix space around pointer's asterisk
The script checkpatch available in new Linux kernel offers an
experimental feature for automatically fix the code in place.
While still experimental, the feature works quite well for simple
fixes, like spacing.

This patch has been created automatically with the script under
review for inclusion in OpenOCD, using the command
	find src/ -type f -exec ./tools/scripts/checkpatch.pl \
	-q --types POINTER_LOCATION --fix-inplace -f {} \;
then manually reviewed.

OpenOCD coding style does not mention the space around pointer's
asterisk, so no check is enforced. This patch only makes the style
uniform across the files.

The patch only changes amount and position of whitespace, thus
the following commands show empty diff
	git diff -w
	git log -w -p
	git log -w --stat

Antonio Borneo 944d3e6771 stlink: add DAP direct driver
STLINK-V3 and the new firmware V2J24 for ST-LINK/V2 provide API
to directly access the DAP registers.
This mode permits to use the native target in cortex_m.c, with no
need to override it with the target in hla_target.c.
Other advantages wrt HLA are: support for Cortex-A cores, support
for SoC multi-core and/or multi AP, support for OpenOCD commands
"dap" thus including control of CSW.
This obsoletes the existing HLA driver for ST-Link, that should
anyway be kept for those cases where it's not possible to update
the ST-Link firmware.

This commit introduces the minimal implementation for direct DAP
access. The implementation is much slower than the HLA because
every memory transfer requires several USB packets. Further
commits will close the performance gap.
The whole ST-Link driver is compiled under BUILD_HLADAPTER, to
remove the need to split the driver between the two modes. This
has to be reworked, but it's quite invasive!
A new interface file stlink-dap.cfg is added and should be used
in place of stlink.cfg to enable the DAP mode.
Documentation is updated and reports limitation on the maximum AP
number that can be accessed by ST-Link for some firmware already
tested.

file core.c to the more adapter-specific file adapter.c
While splitting the old jtag_interface for every driver, put
the fields in the same order as in the struct declaration so
we keep a consistent code across all the drivers.

While other transport specific API could/would be added as
separate ops, nothing is done here for HLA.

Antonio Borneo 0f24549ce9 hla: use the new system_reset API
HLA uses its own internal driver's API to control the adapter's
system reset, but at the same time it calls jtag_add_reset() to
avoid breaking the internal logic of OpenOCD. This implicitly
forces HLA to rely on jtag queue mechanism, even if HLA has no
link with JTAG state machine. It requires HLA to implement an
empty execute_queue() to comply with the JTAG queue.

Modify the HLA framework and the HLA targets to use the new
adapter API for system_reset and decouple HLA from JTAG queue.
Rename the HLA static functions adapter_assert_reset() and
adapter_deassert_reset() to avoid overlap with the global
functions with same name.
While there, fix a minor typo in a comment s/incase/in case/.

Do not remove from HLA the JTAG specific API execute_queue(),
even if not required anymore, because OpenOCD code still has
calls to jtag_execute_queue() in case of non JTAG transport.

Antonio Borneo 8850eb8f2c swd: get rid of jtag queue to assert/deassert srst
The transport SWD uses the JTAG queue to assert/deassert the
system reset srst. This is the major inconsistency that has to be
removed to properly split JTAG and SWD.

Introduce a new driver API, reset(), to controls both the signals
trst and srst in the driver, skipping the JTAG queue. Put the new
API in struct jtag_interface, even if in this patch it's used for
SWD only; the goal is to get it reused by the other transports.

Add the implementation of the API in all the drivers that
implement SWD. Such implementation is almost the same of the old
code in JTAG queue.

Create a wrapper adapter_system_reset() to use the new API and
remove the SWD specific swd_add_reset(). In the wrapper replace
jtag_add_sleep() with jtag_sleep(), because the former uses the
JTAG queue too.
Rename the old jtag_add_reset() as legacy_jtag_add_reset() with
the target to remove it when all drivers would be ported to the
new reset API. Create a new jtag_add_reset() that calls the
legacy function for drivers still on the old reset API.

Use the new API also on JTAG transport for the drivers that can
support both SWD and JTAG.

For the moment, do not modify the implementation of JTAG-only
drivers, which will continue using the usual method. This should
be cleaned-up in future commits.

Marc Schink 2dc88e1479 target/armv7m_trace: Improve SWO frequency auto-detection
The SWO frequency auto-detection with J-Link adapters does not work
properly in the current implementation. This is because the trace layer
has only information about the highest possible SWO frequency supported
by the adapter. With that the trace layer calculates the SWO prescaler
which usually leads to a frequency deviation greater than what is
permitted by J-Link adapters.

Move the calculation of the SWO prescaler from the trace layer into the
trace configuration of the adapter to overcome this problem.
The adapter has the necessary information to choose a suitable SWO
frequency and calculate the corresponding prescaler that complies with
the maximum allowed frequency deviation.

Tested with:
  - STM32L152RC Discovery Kit (ST-Link)
  - EFM32GG-STK3700 (J-Link)

Antonio Borneo f476c9eec4 gdb_server: fix string length with semihosting_fileio
The GDB file-I/O remote protocol extension, used for implementing
the semihosting file I/O, requires the length of strings to
include the trailing zero character, as explicitly stated inside a
comment in GDB source code [1]:
	/* 1. Parameter: Ptr to pathname / length incl. trailing zero.  */

ARM specification for semihosting [2] requires the string length
to not include the trailing zero character, e.g. in SYS_OPEN
specifications:
	"field 3: An integer that gives the length of the string
	 pointed to by field 1. The length does not include the
	 terminating null character that must be present."

The mismatch above requires OpenOCD to add "one" to the string
length before passing it to GDB. Such conversion is missing
either in the generic semihosting provider of the data, the
function semihosting_common(), and in the consumer of the data,
the gdb_server function gdb_fileio_reply().
The conversion is already implemented in the target specific
function nds32_get_gdb_fileio_info(), but it's not the preferred
place for such GDB specific requirement.

This issue affects the semihosting calls "open", "unlink",
"rename" and "system".

Remove the "+1" conversion from nds32_get_gdb_fileio_info().
Add the "+1" conversion in gdb_fileio_reply().

Antonio Borneo 5dc5ed5714 target/cortex_a: use aligned accesses for read/write cpu memory slow
Armv7a is able to read and write memory at un-aligned address, but
only when bit SCTLR.A (Alignment check enable) is zero and the
address belongs to a memory space with attribute "Normal" (see [1]
chapter A3.2.1 "Unaligned data access"). In all the other cases
the memory access will trigger an alignment fault data abort
exception.
Memory attributes are explained in [1] chapter A3.5 "Memory types
and attributes and the memory order model".

Disabling the MMU cause a change in memory attribute, as explained
in [1] chapter B3.2 "The effects of disabling MMUs on VMSA
behavior".
This can cause several issues. e.g. a SW breakpoint on un-aligned
4-byte Thumb instruction, set when MMU is on, can be impossible to
remove when MMU turns off.

While is possible to check all the possible conditions before an
un-aligned memory access, it's clearly more maintainable to skip
such complexity and only perform aligned accesses.

Check the alignment and eventually modify the data size before
calling the functions cortex_a_{read,write}_cpu_memory_slow().
Change the comment in the two functions above to comply with the
new behaviour.

Bohdan Tymkiv 5f42124a40 adi_v5_jtag: avoid RAM exhaustion by limiting jtag queue size
Issue has been found when I tried to read 64 MiB QSPI flash bank.
Bank is memory mapped, default_flash_read() is used for 'flash read_bank'
command. OpenOCD consumed as much as 6.8 GiB of RAM during this
process. Investigation showed that this happens because JTAG queue
is not limited in any way. OpenOCD queues 16 millions of AP reads
allocating all corresponding data structures.

Most of this memory is allocated in:
cmd_queue_alloc (commands.c) - 4.2 GiB
dap_cmd_new (adi_v5_jtag.c) - 2.25GiB

This patch implements a pool of "struct dap_cmd" objects using
linked list. Objects are taken from a pool in "dap_cmd_new()" and
returned to the pool when they are not needed. Size of the pool
is limited to 64K of objects, JTAG queue is forcibly executed
when this limit is reached.

Checked with Valgrind and Clang analyzer - no new warnings.

The command "soft_reset_halt" is deprecated since mid 2013 with
the commit 146dfe3295 ("cortex_m: deprecate soft_reset_halt").
Nevertheless it is still extremely useful with multicore chips
where it allows to reset only one of the cores, option not
available through asserting the chip-wide srst.
Without a better replacement of the command, it's worth fixing it.

Accordingly to ARM DDI 0403E.d, chapter C1.4.1 "Entering Debug
state on leaving reset state", to halt the core at reset both bits
DHCSR.C_DEBUGEN and DEMCR.VC_CORERESET must be set.
Current code only sets the latter bit, relying on having C_DEBUGEN
already set through other commands, e.g. "halt". This prevents the
command "soft_reset_halt" to work if issued as very first command.

Set the bit C_DEBUGEN in command "soft_reset_halt".

Antonio Borneo 1af83682e0 target: fix error on TCL command "return" in target event handler
The TCL command "return" always returns error code JIM_RETURN, to
indicate that the effective error code and message are elsewhere.

In the current implementation, the caller of target's event only
checks for return code JIM_OK and considers any other value,
including JIM_RETURN, as an error condition, thus dumping the
call-trace. The execution is not stopped because the error is not
further propagated, but the error message is annoying and
misleading.

It can be tested running
	openocd -f ./test.cfg
using the following script "test.cfg". You can replace the board
file in line 1, to use a board available in your lab:
  1	source [find board/st_nucleo_f4.cfg]
  2	[target current] configure -event reset-start {}
  3	[target current] configure -event reset-end {return}
  4	init
  5	proc a {} {[target current] invoke-event reset-start}
  6	proc b {} {[target current] invoke-event reset-end}
  7	proc c {} {a;b;echo "arrived at the end"}
  8	c
  9	shutdown
The execution produces:
	./test.cfg:7: Error:
	in procedure 'c' called at file "./test.cfg", line 8
	in procedure 'b' called at file "./test.cfg", line 7

	arrived at the end
that shows the call-trace but does not halt the execution.

The developer can avoid using the "return" command in the event
body by defining a TCL procedure that implements the handler and
that contains the "return" command, reducing the handler body to
a simple call to the procedure above. But this approach is either
not documented nor always intuitive while writing the handler,
causing waste of time to look for the false error.

Modify target_handle_event() to detect the specific return value
of the "return" command and to test the real error code that is,
eventually, specified to the TCL "return" command.

Before commit 877cec20dc
("command: check command mode for native jim commands") all the jim commands

The command '$_TARGET configure -xxx' was therefore applicable on running
OpenOCD to change the target configuration. It is handy e.g. for changing
an event handler or changes of the work area.

Change 'configure' command .mode to COMMAND_ANY to make it possible again.

Antonio Borneo 48478967db mem_ap: fix format of logged addresses
The macro TARGET_ADDR_FMT, defined in helper/types.h, already
includes the prefix "0x" in front of the hexadecimal number,
being defined as:
	#define TARGET_ADDR_FMT "0x%8.8" TARGET_PRIxADDR
An additional "0x" is present in mem_ap; it prints debug messages
with a double "0x" before the address:

	Writing memory at physical address 0x0x5000000c; size 4;

Antonio Borneo 02cd1e39cc target/cortex_m: remove dependency from jtag queue
Since the first commit 09883194f8 that introduced cortex_m, the
code has a delay of 50ms after srst has been asserted.
The specific delay is implemented through the JTAG_SLEEP command
sent in the jtag queue.

To remove the dependency from the jtag queue, replace the delay
with a transport independent function.

In case of jtag transport, this change keeps the same behaviour
only if the jtag queue has been flushed before the delay. This
does not happen if the call to dap_dp_init(), few lines above,
fails while calling a dap_queue_dp_{read,write}(); in this case
the jtag queue will be flushed later, after the delay, while in
the original code the delay would follow the flushing of the
commands already queued. Anyway, this different behavior would
only happen in case of DAP already not responsive so anticipating
the delay in such error condition is not supposed to add further
problems.

This patch is created using the command:

the enable command was executed.

Antonio Borneo 79a92d467d target: unify memory read/write commands
Current code provides two independent implementations for the
memory read/write commands:
a) jim_target_md()/jim_target_mw() for the target specific
   commands "<target> m[dw][bhw]"
b) handle_md_command()/handle_mw_command() for the current target
   commands "m[dw][bhwd]"
The case a) misses the handling of doubleword and calls functions
command_print_sameline() with first parameter NULL because defined
as jim handler.

Remove the code in jim_target_md()/jim_target_mw() and use the
same code in b) for the target specific memory read/write.
This approach also provides support for 64-bit data size, not
present in the implementation in a).
The only drawback is that the implementation of memory read in b)
prints the data also as human readable ASCII characters, feature
missing in the implementation in a). This could introduced later
if it's really needed.

Update the documentation to:
- add 64-bit support
- add phys parameter
- add the count parameter

Add attribute "unused" to target_buffer_get_u8(), now not used
anymore.

Antonio Borneo b3ce5a0ae5 target: use LOG_USER to print errors in events
Events are supposed to be executed asynchronously and not linked
with any command, so it's incorrect printing out an eventual error
using command_print().
Even in the case of events triggered by the command
	<target> invoke-event <event-name>
the eventual error in the event handler is not propagated to the
command, so the command_print() is still not appropriate.

Replace command_print() with LOG_USER() in target_handle_event().
Add further info in the log to identify which event has generated
the error and its associated target.
Before return, clean-up the error message and the stacktrace from
the error already displayed, to avoid propagate them.

Antonio Borneo 84a2cab596 smp: move sub-command "smp_gdb" in file smp.c
The code for this command is currently replicated in cortex_a and
in mips_m4k and is going to be added again for cortex_m.
Plus, it is going to be obsoleted by the HW thread pseudo RTOS.

Consolidate in smp.c a single instance of the command. This will
simplify both obsoleting it and adding it to cortex_m, whatever
change comes first.

Antonio Borneo 246782229f smp: replace commands smp_on/smp_off with "smp [on|off]"
Seams over-engineered having two separate commands to turn SMP
on/off. Plus it is missing the possibility to dump the current
status of SMP and would be weird adding an additional command
for it. Moreover, such commands are replicated in few targets so
it would make sense centralizing them.

- Deprecate the commands "smp_on" and "smp_off".
- Add a new command "smp" that accepts optional parameters
  "[on|off]" and prints the SMP status when run without
  parameters. This replaces the two commands above.
- Put the deprecated and the new command handlers in smp.c
- Update the documentation, except for mips_m4k, since it is not
  available yet.
- Promote the macro foreach_smp_target to global context and use
  it where possible.

Introduce ERROR_TARGET_DUPLICATE_BREAKPOINT
Unify error handling to LOG_ERROR() any error in (xxx_)breakpoint_add()
Remove misleading error messages from handle_bp_command_set()
handle_bp_command_set() returns error if the target does not implement

This may eventually fail if the code memory is not writeable, but there

The functions dap_to_jtag() and dap_to_swd() have been introduced by
3ef9beb52c ("ADIv5 DAP ops switching to JTAG or SWD modes") in
arm_adi_v5.c by using the JTAG queue only.
Later, in 6f8b8593d6 ("ADIv5 transport support moves to separate
files") the functions has been moved in adi_v5_swd.c and adi_v5_jtag.c
but keeping the dependency from JTAG queue.
The functions does not work if the current transport is not JTAG.

Move back the functions in arm_adi_v5.c, replace the input parameter
"target" with "dap", use the transport to detect if the JTAG queue is
present, in case of SWD transport use the proper method, for other
transports report error.
Reuse the ADI v5 sequences already present in jtag/swd.h.
Also, OpenOCD does not support switching to another transport after
the initial selection, so do not change DAP's ops vector.

aarch64-linux-gnu-gdb 8.2 uses "aarch64" as default architecture,
but also supports the value "aarch64:ilp32" and all the values

These values can be displayed on arm gdb prompt by typing
"set architecture " followed by a TAB for autocompletion.

Cody P Schafer 49bd64347a armv7m: always set xPSR.T=1 when starting an algorithm
xPSR.T sets the processor to Thumb mode when set to 1. ARMv7-M only
supports execution of Thumb instructions, so it must always be set to 1.

If xPSR.T is set to 0 on armv7m, a usage fault is generated when a
instruction execution is attempted.

On armv7m, issuing a reset causes the vector table to be examined. PC
and xPSR.T  are loaded from the vector table at byte offset 4. xPSR.T is
taken from the least significant bit this value, PC from the remaining
bits.  This occurs even with `reset halt`, as the reset itself causes
this load to occur without the execution of any instructions.

As a result of this, following a reset with a "bad" value programmed in
the vector table, openocd would be unable to run algorithms on the
target, as running them would immediately result in a usage fault due to
xPSR.T being unset (0).

Allow algorithms to run regardless of the content of the vector table by
explicitly setting xPSR so that xPSR.T=1 prior to executing an
algorithm. One can think of this as openocd more closely emulating a
reset or branch instruction in executing it's algorithms.

Antonio Borneo bff87a7f28 target/cortex_a: enable DSCR_HALT_DBG_MODE during examine
Arm architecture reference manual DDI0406C reports at page 2024 in
table C3-1 the processor behaviour on debug events depending on
the debug-mode (none, monitor or halt), mode selected through the
bits MDBGen and HDBGen in DSCR register.

The halt request is served independently from the debug-mode. Thus
it's useless to enable the halt debug-mode in cortex_a_halt() by
setting the bit HDBGen (macro DSCR_HALT_DBG_MODE).

On the other side, halting for a breakpoint, a watchpoint or a
vector catch requires being in halt debug-mode.
Today HDBGen is set only in cortex_a_halt(), so we are forced to
halt the core at least once before it can be halted for hitting a
breakpoint/watchpoint/vector-catch. This is annoying since there
is no need to halt the target to set a HW breakpoint.

Move in cortex_a_init_debug_access() the selection of the halt
debug-mode, so the mode is set during examine.
To prevent a misconfigured hardware breakpoint/watchpoint/vector
catch to halt the target when OpenOCD has already quit, return to
debug-mode none at OpenOCD exit.

In previous versions of OpenOCD, it was possible to connect to the TCL

In commit bb9d9c6026, the

without noticing that `get_current_target` aborts if there is no current
target, whereas `tcl_new_connection` is perfectly able to handle that
situation.

are OK with a null current target, and use it in `tcl_new_connection`.

Antonio Borneo fac9be64d9 target/cortex_a: remove buggy memory AP accesses
The armv7m debug port provides a direct access to the CPU memory
bus, allowing the debugger to bypass the CPU for every memory
operation.
The armv7a debug port doesn't offer the same feature, mainly
because CPU caches and MMU makes the direct memory access more
tricky. Nevertheless most SoC with armv7a provide direct memory
access through an AHB bus available on another DAP access port,
different from the debug port.

The original port of cortex_a in OpenOCD was inspired from the
working cortex_m code, and provided optional memory access
through the AHB, if present.
The code for AHB access is problematic and partially buggy due
to incomplete management of cache coherency and missing check of
page boundary during virtual address operations.

With the commit 5d458cf727
("target/mem_ap: generic mem-ap target") we have a clean support
for memory access through system buses connected to DAP AP, which
obsoletes the buggy memory AP hack in cortex_a.

Remove any code that uses the memory AP accesses in cortex_a.

Antonio Borneo 1e3ba2046c arm_adi_v5: do not deactivate power domains while trying to clear sticky error
At OpenOCD start-up the operation of clearing the sticky error in
CTRL/STAT register ignores the current value of the power domains
bits CDBGPWRUPREQ and CSYSPWRUPREQ in the same register and
incorrectly set them to zero.
This abrupt disable does not follow the requirement in IHI0031 to
wait for the acknowledgment of power disabled before continuing.
The power domains are then re-enabled immediately after; it is
possible that such short disable period has passed undetected or
has been tested only on devices that do not implement the power
domains.
Anyway, this sequence is incorrect and can generate unexpected
and hard-to-debug issues while OpenOCD attaches to a running
target that implements power domains.

Anticipate the initialization of dap->dp_ctrl_stat and use it
while clearing the sticky bit. This has the additional effect of
avoiding a power disable in the error recovery part of the
function dap_dp_read_atomic().
Keep the same sequence of read/write in dap_dp_init() to avoid
breaking the initialization of some problematic target.
Add comments to document these choices.

Antonio Borneo cf81de7052 target/cortex_a: fix temporary breakpoint during step
Commit c8926d1457 introduces the
context and hybrid breakpoint types beside existing SW and HW
types. The new field "asid" is non-zero only for these new types.

The commit above did not properly initialize "asid" to 0 for a
temporarily HW breakpoint used during single step. This causes
cortex_a_unset_breakpoint() to identify this breakpoint as of
type "hybrid".

Identified through valgrind error:
Conditional jump or move depends on uninitialised value(s)
Actually valgrind triggers a total of 10 messages about use of
uninitialized variables, but they are all caused by the first
conditional jump bases on "asid != 0".

Antonio Borneo 1ba715422f target/arm_adi_v5: fix sync CSW cache on apreg write
Commit 0057c71ab6 updates the OpenOCD
cached values of CSW and TAR registers if these registers are modified
by an apreg command.
The condition to force the update of CSW cache is incorrect and it will
erase the default CSW value.
Moreover, calling mem_ap_setup_csw() does not honor the value requested
in the apreg command because such value is incorrectly bitwise or-ed
with csw_default.

Fix it by updating csw_value, instead of erasing csw_default, and writing
directly in CSW register the new value from the command line.

eSi-RISC is a highly configurable microprocessor architecture for
embedded systems provided by EnSilica. This patch adds support for
32-bit targets and also includes an internal flash driver and
uC/OS-III RTOS support. This is a non-traditional target and required

Antonio Borneo 24654759d5 gdb_server: avoid gdb server for virtual targets
Virtual targets, like mem_ap, do not or cannot implement the required
functionality to accept a GDB connection. In the case of mem_ap, the
method get_gdb_reg_list() is missing and a following connection from
gdb causes OpenOCD to segfault.
OpenOCD opens a GDB port for each target; it's always possible to
connect, by mistake, GDB to one virtual target.

Add a method to check if the target supports GDB connections (for the
moment just checking if get_gdb_reg_list is implemented).
Skip opening a gdb server for every targets that don't support GDB
connections.

Antonio Borneo 56cdc3f3d5 target/cortex_a: poll all targets in SMP node after halt
The periodic poll scans all the targets in the same order they
have been declared in the configuration file.
When one target in a SMP node halts, the transition is detected
in the following poll and this triggers a halt request to all the
other cores of the SMP node.
The targets that will be polled afterwards will be identified as
"halted", but the targets already scanned will remain as
"running" until the next periodic poll.
This creates a race condition with GDB; GDB sets the breakpoints
when runs the target and removes them as soon as the target is
halted. When it receives the halt event, it starts removing the
breakpoints and fails on the targets that are still reported as
"running".

Fixed by polling all the targets in the SMP node before informing
GDB about the halt event.
This implementation is almost copy/paste from the one in aarch64.

Antonio Borneo ab858febb6 gdb_server: add per target option "-gdb-port"
The argument passed to global config command "gdb_port" is usually,
but not always, a TCP port number. In case of multiple targets, this
numeric value is used as the first port of a set of consecutive TCP
ports assigned one per target.
If the argument is not a numeric value (e.g. "pipe", "disabled", ...)
then incrementing it for the next target has no sense.

Add the option "-gdb-port number" to the commands "target create" and
"$target_name configure" to override, for the specific target, the
general global configuration.

This permits to use a per target "-gdb-port disabled", when no gdb
port is required for that specific target.

It also makes possible to choose a custom TCP port number for each
target, overriding the usual sequence of consecutive port numbers.

The current implementation of apsel cannot be executed during the
initialization phase because it queries the DAP AP to retrieve and
print the content of IDR register, and the query is only possible
later on during the exec phase.
But IDR information is already printed by the dedicated command
apid, making redundant printing it by apsel too.
Being unable to run apsel during initialization, makes also apcsw
command (that depends on apsel) not usable in such phase.

Modify the command apsel to only set the current AP, without making
any transfer to the (possibly not initialized yet) DAP. When run
without parameters, just print the current AP number.
Change mode to COMMAND_ANY to apsel and to apcsw.

Put the SWJ-DP back to JTAG mode before exit from OpenOCD.

Use switch_seq(SWD_TO_JTAG) instead of dap_to_jtag(), because the
latter is not implemented on some interfaces. This is aligned
with the use of switch_seq(JTAG_TO_SWD) in swd_connect().

thus the state of translation table gets out-of-sync triggering
	Error: Address translation failure
or even using a wrong address in the memory R/W operation.

In addition, the commit above breaks the case of armv7r by
calling armv7a_read_ttbcr() unconditionally.

Fixed by moving in cortex_a_post_debug_entry() the call to
armv7a_read_ttbcr() on armv7a case only.
Remove the call to armv7a_read_ttbcr() in armv7a_identify_cache()
since it is (conditionally) called only in the same procedure
cortex_a_post_debug_entry().

Fixes: bfc5c764df ("armv7a: cache ttbcr and ttb0/1 on debug
state entry")

On Renesas R-Car, calling 'reset halt' and 'reset init' always made DAP inaccessible. Calling 'reset' and 'halt' seperatly worked fine.
The only differences seems to be the point in time when aarch64_init_debug_access() is called. This patch aligns the behaviour.

of breakpoint was ignored and hard (FPB) breakpoints were set in
'code memory area' 0x00000000-0x1fffffff, soft breakpoints were set above
0x20000000.

The code memory area of Cortex-M does not mean the memory is flash and
vice versa. External flash (parallel or QSPI) is usually mapped above
code memory area. Cortex-M7 ITCM RAM is mapped at 0. Kinetis
has a RAM block under 0x20000000 boundary.

Remove 'auto_bp_type' mode, set breakpoints to requested type.

Remove the erase-value=0 version of algorithm as the new one can check

If the target is an insane slow clocked CPU (under 1MHz) algo
timeouts. Blocks checked so far are returned and the next call

Tomas Vanek eb8912ec38 target, flash: prepare infrastructure for multi-block blank check
'flash erase_check' command runs a check algorithm on a target
if possible. The algorithm is run repeatedly for each flash sector.
Unfortunately every start and stop of the algorithm impose not negligible
overhead.
In practice it means checking is faster than plain read only for
sectors of size approx 4 kByte or bigger. And checking sectors
as short as 512 bytes runs approx 4 times slower than plain read.

The patch changes API call target_blank_check_memory() and related
to take an array of sectors (or arbitrary memory blocks).

Changes in target-specific checking routines are kept minimal.
They use only the first block from the array and process it by
the unchanged algorithm.

default_flash_blank_check() routine repeats target_blank_check_memory()
until all blocks are checked, so it works with both multi-block
and single-block based checkers.

Tomas Vanek 37deb37593 target: fix display halt message logic
If a target is run from gdb and then stopped from OpenOCD telnet interface,
halt does not show message with status and PC registers.

While on it rename 'display' to 'verbose_halt_msg' and use bool type
instead of int.

Tomas Vanek bb9d9c6026 target: use correct target in target-prefixed commands and event handlers
This change contains an alternative to Matthias Welwarsky's #4130
(target-prefixed commands) and to #4293 (event handlers).

get_current_target() must retrieve the target associated to the current
command. If no target associated, the current target of the command
context is used as a fallback.

Many Tcl event handlers work with the current target as if it were
the target issuing the event.

current_target in command_context is a number and has to be converted
to a pointer in every get_current_target() call.

The solution:
- Replace current_target in command_context by a target pointer
- Add another target pointer current_target_override
- get_current_target() returns current_target_override if set, otherwise
	current_target
- Save, set and restore current_target_override to the current prefix
	in run_command()
- Save, set and restore current_target_override to the event invoking
	target in target_handle_event()

While on it use calloc when allocating a new command_context.

Matthias Welwarsky b551c62a7f cortex_a: fix handling of Thumb-2 32bit breakpoints
When debugging Thumb-2 code, Gdb will at times send a
breakpoint packet 'Z0,<addr>,3', the number 3 denoting that
the instruction to break on is 32 bits long. Handle this by
replacing it with two consecutive 16bit Thumb BKPTs and make
sure to save and restore the full, original 32bit
instruction.

Note that this fix is only applicable if you debug a bare-metal program
(like the linux kernel) with the 'wrong' gdb, e.g. use an 
"arm-linux" gdb instead of an "arm-eabi" gdb. But since most people
may not know about the subtle differences between gdb configurations
regarding thumb2 breakpoints it's still valid.

Leverages the existing work that added profiling via DWT_PCSR.

hla_target doesn't have direct access to the mem_ap for doing a bulk

still ~2 order of magnitude faster than halt/resume.

Tomas Vanek 4553abf906 arm_adi_v5: fix wrong addressing after change of CSW_ADDRINC
Problem: If the same memory location is accessed alternatively
by MEM-AP banked data registers without autoincrement and by standard
autoincremented read/write, TAR register is not updated correctly.

How to replicate: On a Cortex-M issue
    mdw 0xe000edf0
multiple times. When poll is on (poll reads the same memory location)
only the first read is correct.
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 20002640
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 00000000

No problems with poll off.
0xe000edf0: 01000000
0xe000edf0: 01000000
0xe000edf0: 01000000

mem_ap_setup_tar() writes to MEM_AP_REG_TAR if requested TAR value
changed or CSW_ADDRINC_... is currently active.
However if an autoincremented access has been issued and autoinc
switched off in CSW afterwards, TAR does not get updated.

The change introduces mem_ap_update_tar_cache() which is called
after queuing of any access to MEM_AP_REG_DRW. It simulates
TAR increment to keep tar_value in sync with MEM_AP.
Crossing tar autoincrement block boundary invalidates cached value.

mem_ap_write() and mem_ap_read() do not check tar autoincrement
block boundary, mem_ap_setup_tar() is called before each transfer instead.

dap_invalidate_cache() is introduced to ensure invalidation
of all cached values during dap_dp_init() and swd_connect()

Rework the code to check the alignment/size of the read/write operation,
and use the Memory Access mode to read aligned 32 bit memory.
When using unaligned access, or 8 or 16 bit reads, use LDR{BHW} and STR{BHW}
instead.

The exception handling is still the same as it was before (meaning it breaks
when things go wrong), but I can now read an 8 bit register correctly.

Christopher Head 02df0abb54 Cortex-M: fix stale DHCSR cache values
In cortex_m_assert_reset, in two locations, DHCSR is written directly
using mem_ap_write_u32. This means that the cached version,
target_to_cm(target)->dcb_dhcsr, is not updated when these writes are
performed, so subsequent writes to DHCSR that use
cortex_m_write_debug_halt_mask will change those bits back to their old
values which, unless modified in that particular invocation, come from
the cache. This causes an actual, observable bug on an STM32F7 in which
running “reset run” immediately after “program” can in some cases result
in execution proceeding with C_MASKINTS set (it is cleared on line 1021
but is then set immediately afterward in cortex_m_clear_halt), causing
failure of the application. Replace these mem_ap_write_u32 calls with
cortex_m_write_debug_halt_mask calls to do the same jobs.

Extended and revised version of my original patch submitted by Dmytro
here: http://openocd.zylin.com/#/c/3390

This driver is using pure SPI mode, so the flash base address is not
used except some flash commands (e.g. "flash program") need it to
distinguish the banks.

Example config with all 3 chip selects:
flash bank flash0 ath79 0 0 0 0 $_TARGETNAME cs0
flash bank flash1 ath79 0x10000000 0 0 0 $_TARGETNAME cs1
flash bank flash2 ath79 0x20000000 0 0 0 $_TARGETNAME cs2

Example usage:
> flash probe flash0
Found flash device 'win w25q128fv' (ID 0x001840ef)
flash 'ath79' found at 0x00000000
> flash probe flash1
No SPI flash found
> flash probe flash2

Salvador Arroyo 2279c23cde mips32, add support for micromips in debug mode
Micromips is 16bit oriented, branch and jumps are
16 bit based. The upper half 16bits of a 32bit instruction
with the major opcode, must go first in the instruction
stream, hence the SWAP16 macro and swap16 array function,
needed if the code is written as 32 bit word in little endian
cores. Endianess info added to ejtag_iinfo. Pointer to
ejtag_info and isa field added to pracc context.
MIPS32 code are renamed to MIPS32_ISA_...
To select the isa, the new code has an additional isa parameter
(1 for micromips, 0 for mips32).
In JR instruction the isa bit must be set to execute
micromips code.
The suffix u is added to the OP codes to avoid signed/unsigned
comparison errors and to make sure the right shift is
performed logically.
The isa in debug mode is updated in the poll function.
Code for miniprograms, in kernel mode, need to be converted.
CFI code only for mips32.

Matthias Welwarsky bf1efe05bb aarch64: run control rework
This patch contains a major overhaul of the target run control,
mainly for the sake of satisfying gdbs ideas of how a target
should respond to various control requests for the debugger.

The changes allow gdb a slightly better control on how cores
are stepped: a core can be single-stepped while 
other cores remain halted or continue normal execution 
until the single-stepped core halts again.

Also, on any halting event (user command or breakpoint) the
system is brought into a stable state with all cores halted
before the halt is signaled to the debugger.

This patch also transitions the target code to make use of the
new CTI abstraction instead of accessing CTI registers directly.
