commit fe239d9ffe8745effcd58e825e7169dd902c5c22
Author: Antonio Borneo <bor...@gm...>
Date:   Mon May 18 10:56:07 2026 +0200

    target: profile: avoid division by zero
    
    Issue detected by scan-build.
    
    The function target_profiling() can return with num_of_samples==0
    and this will trigger a division by zero.
    
    Check the value of num_of_samples before continuing.
    While there, simplify the return path and the return value.
    
    Fixes: dcf628298534 ("target: filter and sort pc samples before storing")

    target: riscv: drop use of type time_t
    
    This is the only code in OpenOCD that directly uses time_t.
    This type assumes different size and sign depending on the host OS
    and should not be used directly.
    
    Replace it by using the OpenOCD helper timeval_ms().

    rtt: Fix reading inactive channels
    
    The current implementation reads the names of inactive channels, which
    can result in invalid data reads, memory access violations, and broken
    output, for example:
    
    > rtt channellist
    [riscv.cpu] Failed to read memory (addr=0x0)
    {
        {
            name  Terminal
            size  0x400
            flags 0x0
        }
    
    Skip reading the names of inactive channels to avoid invalid memory
    reads and broken output.

commit 56d91e42e30585358a03e9f31c0a9f4253fb3f3c
Author: hhoang308 <huy...@gm...>

    target/rtt: support 64-bit targets by using dynamic offsets
    
    The current RTT implementation hardcodes the channel structure size to
    24 bytes and uses fixed offsets for control block members. This conforms
    to the ILP32 (32-bit) layout but fails on LP64 (64-bit) targets such as
    RISC-V 64-bit or AArch64.
    
    On 64-bit targets:
    - Pointers are 8 bytes, increasing the channel struct size to 32 bytes.
    - Member offsets are shifted due to alignment.
    - Critically, the 'read_pos' offset moves from 0x10 (32-bit) to 0x18
      (64-bit).
    
    The existing code writes to offset 0x10 to update the read position. On
    a 64-bit target, offset 0x10 corresponds to 'SizeOfBuffer'. This
    overwrites the buffer size with the read position value, causing memory
    corruption and immediate firmware crashes (boot loops).
    
    This patch introduces a dynamic parameter structure that selects the
    correct offsets and sizes at runtime based on 'target->address_bits'.
    It has been verified on a RISC-V 64-bit target running Zephyr RTOS.

    jtag/core: fix blocked polling in unknown state of jtag_xrst
    
    Patch [1] neglected three state character of jtag_trst variable,
    similarly the original code did for jtag_srst.
    
    Block polling only if SRST / TRST state is known and set.
    
    Fixes: [1] commit eeacc589af60 ("jtag/core: fix is_jtag_poll_safe() logic")

    tcl/target: Fix max32625 support
    
    Interfaces used: jlink, olimex-arm-usb-tiny-h, cmsis-dap
    
    On openocd master the 'reset halt' command gives the following:
        "Error: timed out while waiting for target halted"
    
    This commit causes 'reset halt' to work with the jlink and olimex
    adapters. The error is no longer logged and the board halts.
    
    With cmsis-dap the error is no longer logged. However the board
    fails to remain halted unless the command is issued in telnet.

commit dcf6282985345be5ff79a4528321db5f0bcb2849
Author: Richard Allen <rs...@gm...>
Date:   Fri Nov 29 12:27:45 2024 -0600

    target: filter and sort pc samples before storing
    
    Add a comparator and pre-sort the program-counter
    samples before saving histogram.
    
    These changes make future improvements easier to implement.

    Use the USB product name handling provided by the adapter core instead
    of having it in the driver code itself.
    
    Keep the legacy 'openjtag device_desc' command for backwards compatibility,

commit e4941a039789227666d5fa2799613db0ca1c7d74
Author: Marc Schink <de...@za...>
Date:   Mon Apr 27 07:59:25 2026 +0200

    adapter/ftdi: Use adapter core USB product name handling
    
    Use the USB product name handling provided by the adapter core instead
    of having it in the driver code itself.
    
    Keep the legacy 'ftdi device_desc' command for backwards compatibility,
    but mark it as deprecated.

 These interfaces have several commands, used to configure the driver
 before initializing the JTAG scan chain:
 
-@deffn {Config Command} {ftdi device_desc} description
-Provides the USB device description (the @emph{iProduct string})
-of the adapter. If not specified, the device description is ignored
-during device selection.
-@end deffn

 @deffn {Config Command} {ftdi channel} channel
 Selects the channel of the FTDI device to use for MPSSE operations. Most
 adapters use the default, channel 0, but there are exceptions.

commit a41341bbf7f1e06910ce967b7e199cf64ab77c3a
Author: Marc Schink <de...@za...>
Date:   Mon Apr 27 07:55:19 2026 +0200

    adapter: Implement USB product name handling
    
    Multiple adapter drivers currently implement their own 'device_desc'
    commands, leading to duplicated code. Move this functionality into the
    adapter core, similar to how device serial handling is implemented.
    
    Additionally, rename the command from 'device_desc' to 'product_name' to
    more accurately describe its purpose and align with what it actually does.
    
    Driver specific changes will follow in a separate patch series.

commit 2acd694e3c6d7e3fb11d4ad92b4440f2b51db2d3
Author: Marc Schink <de...@za...>
Date:   Mon Aug 4 12:57:05 2025 +0200

    helper: Use proper return values for duration_{start,measure}
    
    The return value of gettimeofday() is used directly as return value of
    duration_{start,measure}, but checked inconsistently against 0 or
    ERROR_OK. Use proper return values and make the code more consistent.
    
    While at it, remove unnecessary parentheses to make checkpatch happy.

commit 2fb8a4752ac59c134209ffec497ba96e3f51f520
Author: Evgeniy Naydanov <eu...@gm...>
Date:   Thu Mar 12 14:52:21 2026 +0300

    target/riscv: drop version-specific `arch_state()`
    
    Drop these placeholders.
    
    This is a part of the effort to eliminate "fake" `riscv013_target` and
    `riscv011_target` `target_type`s.

commit eeacc589af6062e38658e19dfb6f315f9e5db26c
Author: Tomas Vanek <va...@fb...>
Date:   Wed Apr 29 11:07:21 2026 +0200

    jtag/core: fix is_jtag_poll_safe() logic
    
    RESET_SRST_NO_GATING reset config option is used also for
    other transports, mainly for SWD.
    
    Disable polling implicitly while SRST is gating the debug
    HW regardless the selected transport.
    
    While on it, add FIXME comment to mark similar issue with
    sensed SRST signal. Currently there is no support for
    SRST sensing in drivers so no way to test eventual change.

    Add sensed_ prefix to make sure the variables are not
    mismatched mainly with the active srst control ones.
    
    While on it update sense_handler() comment
    
    No functional change.
    int type variables misused as a bool left as is.

commit af6c19d59db1dc123e7628165166f15772b80714
Author: Tim Newsome <ti...@si...>

    target: base poll frequency on wall time
    
    Replaces code that would count number of invocations.
    
    This is based on [1].
    
    The behavior is changed, namely:
    * `TARGET_EVENT_GDB_HALT` is not called -- the user can hit Ctrl-C if he
      needs to halt the target, this use of the callback seems
      counterintuitive. See [2].
    * There is no early-exit when re-examining the target fails -- there are
      still other targets that need to be processed.

commit 97a11c4f5319a4cdfe8cc1668b4ccf7680c1b639
Author: William Markezana <wil...@gm...>
Date:   Fri Apr 10 12:45:43 2026 -0400

    jtag/drivers: add T-Head CK-Link JTAG adapter driver
    
    Driver for T-Head CK-Link Lite V2 probes, including the Bouffalo Lab
    BL616/BL702 CK-Link clones used as built-in debuggers on BL61x/BL70x
    evaluation boards. The wire protocol is a framed command format over
    USB bulk endpoints, reverse-engineered from T-Head's DebugServer.
    
    Implements JTAG_SCAN via the probe's batch opcode, with IR caching
    across execute_queue boundaries and end-of-queue flush so OpenOCD's
    Capture-IR validation reads real hardware data. Speed is programmable
    (freq_kHz = 48000 / (N+1), capped at the DebugServer-validated 2526
    kHz). Probes are matched against a built-in VID/PID list (overridable
    via 'adapter usb vid_pid') and by adapter serial.
    
    Known protocol limitations, surfaced as one-time warnings:
    
      - Single batch entry encodes IR/DR bit-counts in single bytes;
        scans > 255 bits are clamped with TDI pass-through on the
        un-shifted portion.
      - The T-Head DTM's Capture-IR returns the current IR value rather
        than the IEEE 1149.1 'xxx01' pattern; init pre-loads IR = IDCODE.
      - No TMS-sequence opcode: JTAG_TMS and JTAG_PATHMOVE return
        ERROR_JTAG_NOT_IMPLEMENTED.
      - Multi-TAP chains are not supported.
      - RTCK is not supported.
    
    Tested against BL618 and BL702 evaluation boards.

+@deffn {Interface Driver} {cklink}
+Driver for the T-Head CK-Link Lite V2 JTAG probe and Bouffalo Lab
+BL616/BL702 clones, including the built-in debugger on Bouffalo BL618
+evaluation boards. Communication is over USB bulk endpoints using a
+T-Head DebugServer-compatible framed command protocol.
+
+The driver only supports JTAG transport and a single-TAP chain. The
+probe runs at a fixed clock; @command{adapter speed} requests are
+accepted but ignored (with a one-time warning). @command{JTAG_TMS} and
+@command{JTAG_PATHMOVE} are not supported by this probe's protocol.
+
+By default the driver matches 0x42bf/0xb210 (Bouffalo) and
+0x32bf/0xb210 (T-Head). The built-in list can be overridden via
+@command{adapter usb vid_pid}.

 @deffn {Interface Driver} {cmsis-dap}
 ARM CMSIS-DAP compliant based adapter v1 (USB HID based)
 or v2 (USB bulk or TCP/IP).
