Evgeniy Naydanov 1c168242e9 target/riscv: simplify reset
Since the deletion of `-rtos hwthread`, there is no need to treat harts
with `-rtos` specified differently on reset.

Hang Xu 2370d78249 target/riscv: fix the bug of using S2 register in read_memory_progbuf
We should avoid using x16~x31 register in program buffer because there
are no such general purpose registers in RVE(Embedded) extension.
For targets that support rvE, when the parameter increment=0
and count>1 of the read_memory_progbuf function, openocd will cause
an error due to the use of the s2 register.
For example:
{Command} {riscv repeat_read} count address [size=4]

"FENCE" opcode with empty predecessor and successor sets.

Such instruction has no effect and is reserved for future use
as a HINT instruction (RISC-V Unprivileged ISA spec V20191213,
section 2.9).

This patch fixes it by using the proper "fence rw,rw"
instruction.

Tomas Vanek 59763653c6 target/cortex_m: add SMP support for Cortex-M
Cortex-M support for SMP multicore targets.

This SMP implementation unlike older ones does not act
on the first halted target found. It polls targets
until a SMP group is finished and stores eventual
'halted' events instead of emitting them. As soon as polling
of a group is done, poll proceeds with SMP related tasks.
This approach improves detection of a reason why debug
stopped - a correct reason is detected for all targets,
not only for the first found.
Drawback: SMP target group should be defined in the same
order as the targets were defined.

Obsolete gdb 'J' packet/smp_gdb command core switching is not implemented,
use with rtos hwthread.

Only one core is resumed if debug_execution is requested.

Some ideas taken from Graham Sanderson's [4936]
and src/target/aarch64.c

Added error checking of armv7m_restore_context().

Koudai Iwahori d0436b0cda armv8: Add support of pointer authentication
When pointer authentication is enabled, some upper bits of the link
register (LR[63:VA_SIZE]) are used to store a signature. Therefore, GDB
need to remove the signature to get backtraces.
GDB has support of pointer authentication. When pointer authenticaion is
enabled, GDB requests 8-bytes mask to the target to remove the
signature. mask[63:VA_SIZE] should be all set and mask[VA_SIZE-1:0]
should be all cleared. GDB removes the signature by addr&~mask or
addr|mask.
I added a feature to provide the mask for pointer authentication.

Antonio Borneo da34e36cdb nds32: drop it, together with aice adapter driver
The target nds32 and its companion adapter aice have not received
any real improvement since 2013.
It has been hard to keep them aligned during the evolution of
OpenOCD code, with no way for maintainers to really check if they
are still working.
No real documentation is present for them in OpenOCD.
The nds32 code triggers ~50 errors/warnings with scan-build.

The arch nds32 has been dropped from Linux kernel v5.18-rc1.

For all the reasons above, this code has been deprecated with
commit 2e5df83de7 ("nds32: deprecate it, together with aice
adapter driver") and tagged to be dropped before v0.13.0.

Let it r.i.p. in OpenOCD git history.

While there, drop from checkpatch list the camelcase symbols that
where only used in this code.

Marcin Niestroj 7dd5b6a464 rtt: fix corner-cases of finding control block
This patch fixes two corner-cases of finding RTT control block.

The first one is when there was a partial match (even single byte) at
the end of loaded buffer (uint8_t buf[1024]), but this was not part of
full match. In that case `cb_offset` was not updated correctly and the
returned `*address` was lower by the legth of the partial match. In case
of searched 'SEGGER RTT' (the default control block ID) string, it was
enough to match `buf[1023] == 'S'`, which is quite likely to happen, and
the `*address` was offset by 1 (e.g. it was 0x20000fff instead of
0x20010000).

Updating (or even maintaining) `cb_offset` is not needed, as start
address of control block can be calculated based on memory address that
was loaded into `uint8_t buf[1024]`, the offset within this buffer and
the length of expected string.

The second issue is when control block is prepended with a byte that
matches first ID character, e.g. there is `SEGGER RTT` control block ID
is prepended by another `S`, making memory contents be `SSEGGER RTT`. In
that case there was no match found.

Fix that issue by making sure that tested byte is always compared with
first byte of expected control block ID.

While at it, change names of local variables to better describe their
meaning.

Antonio Borneo 2b6fe8f1ab target: fix assert in 'monitor profile' on constant PC
When target is stopped in WFI/WFE or is in an infinite loop, the
sampled PC will always return the same value.
Command 'profile' requires that distance between min and max PC
should be at least 2, which is not the case for constant PC, and
incorrectly enforces the check through as assert().

Move the code that reads the optional parameters 'start' and 'end'
and check the gap 'end - start' before running the profile.
For self-computed min and max, increase max (or decrease min) to
match the required constraint.
Drop the assert().

Antonio Borneo a51ac964c6 target: fix unsigned computation in 'monitor profile'
The implementation of command 'monitor profile' has few
issues:
- the address_space is a signed int, so cannot wrap-around on
  space over INT_MAX;
- max address is incremented without check for overflow;
- assert() used on errors instead of returning error codes;
- only handles 32 bits PC;
- output file created and left empty on error.

This patch fixes the first two issues, as a wider fix would be too
invasive and should be postponed in a following series.

Clang complains about the variable 'orig_dfsr' that can be used
uninitialized both in cortex_a_read_cpu_memory() and in
cortex_a_write_cpu_memory().

The issue is caused by an incorrect error path that used to jump
through 'goto out'. The code after the label 'out' is specific to
handle the case of an error during memory R/W; it is incorrect to
jump there to handle an error during the initialization that
precedes the memory R/W.

Replace the 'goto out' with 'return retval'.
Remove the label 'out' that is now unused.

Antonio Borneo c6fe10de75 arm_adi_v5: fix SIGSEGV due to failing re-examine
Commit 35a503b08d ("arm_adi_v5: add ap refcount and add get/put
around ap use") modifies the examine functions of mem_ap, cortex_m,
cortex_a and aarch64 by calling dap_put_ap() and then looking again
for the mem-ap and calling dap_get_ap().
This causes an issue if the system is irresponsive and the examine
fails and left the AP pointer to NULL. If the system was already
examined the NULL pointer will cause a SIGSEGV.

Commit b6dad912b8 ("target/cortex_m: prevent segmentation fault
in cortex_m_poll()") proposes a fix for one specific case and only
on cortex_m.

Modify all the examine functions by skipping look-up for the AP if
it was already set in a previous examine; the target's AP is not
supposed to change during runtime.

Remove the partial fix for cortex_m as it is not needed anymore.

target/riscv: Don't always read on DMI batch write (#768)
Indicate to the JTAG driver that it does not need
to read and return the DR register value after scanning the
JTAG chain.

riscv_batch_run(), calls jtag_add_dr_scan() to schedule a
DR scan operation. Eventually, this will result in the JTAG
driver performing a JTAG scan to write to or read from DR.
The decision on whether to write to and/or read from DR
register is determined by the second parameter to
jtag_add_dr_scan(), i.e. a "struct scan_field".
Of particular interest here is if
batch->fields[i]->in_value is not NULL, the JTAG developer
must return the DR value collected from the JTAG  scan
operation.

When creating the DR scan operation instruction with
riscv_batch_add_dmi_write(), batch->fields[i]->in_value points
to a location in batch->data_in buffer,
meaning batch->field[i]->in_value is not NULL, and the JTAG
developer must therefore read and return the DR value collected.
The returning of the DR value is redundant in a write
operation.

This patch set batch->fields[i]->in_value to NULL to indicate
the DR value need not be returned. This allows the JTAG
developer to optimize away any code associated with returning
the DR value.

Normally, the extra work to return the DR value is negligible.
However, in one usecase it introduces significant delays
In this use case a JTAG driver forwards
all JTAG scan to a server on a network. If the server has to
return the DR value, it has to perform the JTAG scan before
replying to the JTAG driver, and only then the JTAG driver
can send the next JTAG scan operation. However, if there is
no need to return the DR value, the server can
acknowledge the JTAG operation request immediately,thus
signalling  to the JTAG driver that it is free to send the next
JTAG scan operation. At the same time of receiving the second
JTAG operation the server will process the original JTAG scan.
This saves time and mitigates network delay. Also, not having
to include the DR value in resulting in smaller reply packet
from server to JTAG driver and save on network traffic.

This doubles download speeds to spike using remote bitbang.

Erhan Kurubas 535de48ca6 target/xtensa: remove redundant call for `TARGET_EVENT_HALTED`
`xtensa_do_step` is invoked from `xtensa_prepare_resume` to silently
step over BP/WP before resuming.
For example; in the case of WPs (DEBUGCAUSE_DB), in the current
implementation `xtensa_do_step` will generate one more
`TARGET_EVENT_HALTED` after the original one caused by WP itself.

This patch moves the halted event cb call after
the step is done successfully.

[riscv] step operation handler should respect handle_breakpoints parameter (#741)
* [riscv] step operation handler should respect handle_breakpoints parameter

When step operation is requested the OpenOCD frontend (like gdb server
or TCL server) has an option to control how existing breakpoints are
handled upon step.

Some OpenOCD frontends (like gdbserver) may choose to disable special
handling of existing breakpoints - thus handle_breakpoints is set to 0,
while others (like TCL server) expect target handler to temporary
disable the matching breakpoint to allow the step operation to complete
successfully.

In the current implementation handle_breakpoints parameter was ignored
by target-specific handler. Thus, the following sequence of commands:

```
halt
bp <current_pc> 4
step
```

Resulted in *step* operation to not change PC because of bp match.

This commit addresses this issue.

* Adjusted calls to logging facilities (addressed review comments)

we already have a target associated with each operation, and from there
we can find the desired hart id. dm013_info_t already tracks
current_hartid (meaning which hart ID is currently selected by the DM).

This makes the code simpler to understand. Also it turns out we don't
need to make sure the correct hart ID is currently selected because
there are only a few real entry points.

authdata_write" without arguments. In such case 'value' is not
initialized and is passed to and used by r->authdata_write().

Reorganize the code to:
- detect the correct amount or command's arguments;
- drop the LOG_ERROR() on ERROR_COMMAND_SYNTAX_ERROR;
- drop the 'else' after 'return'.

Antonio Borneo fd2a44ab55 target/riscv: fix undefined operation
Scan-build reports:
	Logic error: Result of operation is garbage or undefined
	riscv.c:1614 The result of the left shift is undefined due
		to shifting by '4294967281', which is greater or
		equal to the width of type 'target_addr_t'

This is a false warning due to clang that considers the impossible
case of 32 bits hart (xlen = 32) in SATP_MODE_SV48 mode
(info->va_bits = 48).
Under such case:
	riscv.c:1614 ... ((target_addr_t)1 << (xlen - (info->va_bits - 1))) ...
the shift amount wraps around the unsigned type and assumes the
value 4294967281 (0xfffffff1).

Use assert() to prevent clang from complaining.

	Unix API: Allocator sizeof operand mismatch
	dsp563xx.c:2143 Result of 'calloc' is converted to a pointer
		of type 'uint8_t', which is incompatible with sizeof
		 operand type 'uint32_t'

It's a false positive because calloc() is properly used in this
case, as the uint8_t array is used in blocks of 4 elements to read
or write uint32_t values.

Either
	calloc(sizeof(uint32_t), count);
and
	malloc(count * sizeof(uint32_t));
keep triggering the same warning.

Drop the warning by using the constant '4' as size of uint32_t, as
