Marek Vrbka adb9c3209e target/riscv: Stop caching writes to DPC
Since DPC is WARL (same rules as MEPC according to
the specification), it is possible that
writes to it won't result in the exact value present.
Therefore, writes to it shouldn't be cached, same as
with other WARL registers.

We make use of r0 and r1 to transfer 64-bit quantities to/from DCC.

Artemiy Volkov d20304b3fb target/arc: do not invalidate icache when (un)setting breakpoints
Currently, instruction cache is being invalidated in
arc_{un,}set_breakpoint() regardless of whether the breakpoint's type is
HW or SW. For SW breakpoints, this has no net effect as the caches are
flushed as a by-product of overwriting instructions in main memory and
is thus merely unnecessary; but for HW breakpoints this invalidation is
not preceded by a flush and might lead to loss of data. This patch
removes the invalidate() call altogether to correct this undesired
behavior for HW breakpoints.

With this patch applied, all supported HW breakpoint tests from the gdb
testsuite are now passing with the arc-openocd backend.

Antonio Borneo bdf73617e7 armv8_dpm: fix registers read at debug entry
The comment above armv8_dpm_read_current_registers() doesn't match
the implementation, as the function reads all the registers from
ARMV8_PC and above.
The registers currently read are not relevant to answer to the
usual GDB initial request through the 'g' packet. Plus the lack of
differentiation per core state (AArch32 vs AArch64) causes the
read of not existing registers in AArch32 triggering errors, as
tentatively fixed by https://review.openocd.org/5517/

Fix the code to read the registers initially required by GDB.
Modify the comment to report the register list in AArch32 and in
AArch64.
Keep the extra checks inside the read loop, even if they are
mostly irrelevant; this could prevent errors if someone needs to
extend the number of registers to read.

The current implementation of the register's description in
OpenOCD does not allow to discriminate among AArch32 and AArch64
registers. Add a TODO comment to highlight it.

Marek Vrbka d41a204d82 image: fix binary detection for small files
Previously, if the image file was less than 9 bytes long,
it was assumed to be an error when it could be a binary
image file. This patch makes OpenOCD detect these cases
as binary files.

Artur Rojek 3b38226370 mips32: add per-cpu quirks feature
Introduce the ability to detect CPUs based on CP0 PRId register and
apply cpu specific quirks, which alter the default ejtag behavior.

First of those is EJTAG_QUIRK_PAD_DRET, which makes sure extra NOPs are
placed after the DRET instruction on exit from debug mode. This fixes
resume behavior on Ingenic JZ4780 SoC.

The proper detection of some (currently unsupported) CPUs becomes quite
complicated, so please consult the following Linux kernel code when
adding new CPUs:
* arch/mips/include/asm/cpu.h
* arch/mips/kernel/cpu-probe.c

Parshintsev Anatoly a8fedebcb4 [riscv] refactor functions that register read/write via progbuf
The motivation for this refactor is to fixup error handling for some
corner cases. These functions attempt to cache S0 register and only then
perform a bunch of extra checks to figure out if the requested register
is valid one in this context. The problem is that there are few corner
cases when _*progbuf functions could receive a GPR as an input. For
example, an abstract read could fail (for whatever reason) leading to
infinite recursion:

````
save S0 -> read S0 -> save S0 -> read S0 -> ...
```

The case described above could be fixed by adding extra sanitity checks,
however I decided to make these functions more modular since I find
self-contained functions easier to read.

Lot of messages was logged as LOG_WARNING, but the operation failed
immediately. Sometimes no error message was logged at all.
Add missing messages, change warnings to errors.

Sometimes ERROR_TARGET_INVALID was returned. Some command handlers
returned ERROR_OK! Always return ERROR_TARGET_NOT_HALTED.

While on it use LOG_TARGET_ERROR() whenever possible.
Prefix command_print() message with 'Error:' to get closer
to LOG_TARGET_ERROR() variant.

Error message was not added to get() and set() methods of
struct xxx_reg_type - the return value is properly checked and a message
is logged by the caller in case of ERROR_TARGET_NOT_HALTED.

While not affecting the function's main purpose, an error has
crept into arc_save_context() that results in logging wrong register

trivial program and halting at entry to main, the following values are
printed to the log:

Debug: 2952 2020 arc.c:909 arc_save_context(): Get aux register regnum=67,
name=status32, value=0xffffffff

After the change, the register contents make much more sense:

Debug: 2923 3934 arc.c:889 arc_save_context(): Get core register regnum=0,
name=r0, value=0x00000000

Evgeniy Naydanov 8d660ea98d target/riscv: refactor read_memory_progbuf()
There were a couple of problems with previous implementation:

* Misalligned read would return ERROR_OK and print all zeroes.

* CMDERR_BUSY for abstract access was improperly handled:

According to the spec, no assumptions can be made about DM_DATA*
contents in such a case, but these were considered valid values from
memory.

* A fallback to one element read was implemented when DMI_STATUS_BUSY
occurred during batch reads, even though this can be accounted for.

Antonio Borneo 144d940a8b Revert "target/image: zero-initialize ELF segments up to p_memsz"
This reverts commit 047b1a8fc2.

Commit 047b1a8fc2 ("target/image: zero-initialize ELF segments
up to p_memsz") breaks the backward compatibility introducing some
problem:
- an empty bss segment with paddr in SRAM gets zero filled at load
  but does not survive after a reset, causing verify to fail;
- an empty bss segment with paddr in FLASH causes excessive flash
  usage, which can exceed flash size (causing error) and makes
  flash aging faster.

Revert it while looking for a better implementation.

Poll failure just means poll failed. It's safer to assume the target is
still running, because then if it is running and subsequently halts we can
relay this to gdb correctly. We can't do the other way around, because once
gdb thinks the target has halted, it can't deal with it spontaneously
running.

Antonio Borneo 8670ad4caa target/espressif: fix clang report on list use
It looks like a false positive.
Scan-build considers as possible to:
- have list_empty() return false;
- list_for_each_safe() to not execute any loop, thus not assigning
  a non-NULL value to 'block';
- the NULL pointer 'block' is passed to list_del().
This is not possible because with list_empty(), the loop runs at
least once.

Rewrite the function to simplify the code and making it easier for
scan-build to check it.

This also drops an incorrect use of list_for_each_safe(), where
the 'safe' version was not required.

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]

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().

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

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.

Add the default case to cover other values of size.

After this fix, clang still complains on the same line, this time
misunderstanding the limits of the loop and considering that
buf_bswap16() only swaps the first 16 bits, thus passing not
initialized value data[2] to adbg_compute_crc()

Replace malloc() with calloc() to silent it.

`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)

This was used to track which hart a given operation must apply to. But
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.
