| Security Vulnerability Related |
| ****************************** |
| |
| The following CVEs are addressed by this release: |
| |
| More detailed information can be found in: |
| https://docs.zephyrproject.org/latest/security/vulnerabilities.html |
| |
| Known issues |
| ************ |
| |
| You can check all currently known issues by listing them using the GitHub |
| interface and listing all issues with the `bug label |
| <https://github.com/zephyrproject-rtos/zephyr/issues?q=is%3Aissue+is%3Aopen+label%3Abug>`_. |
| |
| API Changes |
| *********** |
| |
| * Driver APIs now return ``-ENOSYS`` if optional functions are not implemented. |
| If the feature is not supported by the hardware ``-ENOTSUP`` will be returned. |
| Formerly ``-ENOTSUP`` was returned for both failure modes, meaning this change |
| may require existing code that tests only for that value to be changed. |
| |
| * The :c:func:`wait_for_usb_dfu` function now accepts a ``k_timeout_t`` argument instead of |
| using the ``CONFIG_USB_DFU_WAIT_DELAY_MS`` macro. |
| |
| * Added disconnect reason to the :c:func:`disconnected` callback of :c:struct:`bt_iso_chan_ops`. |
| |
| * Align error handling of :c:func:bt_l2cap_chan_send and |
| :c:func:`bt_iso_chan_send` so when an error occur the buffer is not unref. |
| |
| * Added :c:func:`lwm2m_engine_delete_obj_inst` function to the LwM2M library API. |
| |
| Deprecated in this release |
| |
| * :c:macro:`DT_CLOCKS_LABEL_BY_IDX`, :c:macro:`DT_CLOCKS_LABEL_BY_NAME`, |
| :c:macro:`DT_CLOCKS_LABEL`, :c:macro:`DT_INST_CLOCKS_LABEL_BY_IDX`, |
| :c:macro:`DT_INST_CLOCKS_LABEL_BY_NAME`, and |
| :c:macro:`DT_INST_CLOCKS_LABEL` was deprecated in favor of utilizing |
| :c:macro:`DT_CLOCKS_CTLR` and variants. |
| |
| * :c:macro:`DT_PWMS_LABEL_BY_IDX`, :c:macro:`DT_PWMS_LABEL_BY_NAME`, |
| :c:macro:`DT_PWMS_LABEL`, :c:macro:`DT_INST_PWMS_LABEL_BY_IDX`, |
| :c:macro:`DT_INST_PWMS_LABEL_BY_NAME`, and |
| :c:macro:`DT_INST_PWMS_LABEL` was deprecated in favor of utilizing |
| :c:macro:`DT_PWMS_CTLR` and variants. |
| |
| * :c:macro:`DT_IO_CHANNELS_LABEL_BY_IDX`, |
| :c:macro:`DT_IO_CHANNELS_LABEL_BY_NAME`, |
| :c:macro:`DT_IO_CHANNELS_LABEL`, |
| :c:macro:`DT_INST_IO_CHANNELS_LABEL_BY_IDX`, |
| :c:macro:`DT_INST_IO_CHANNELS_LABEL_BY_NAME`, and |
| :c:macro:`DT_INST_IO_CHANNELS_LABEL` were deprecated in favor of utilizing |
| :c:macro:`DT_IO_CHANNELS_CTLR` and variants. |
| |
| * :c:macro:`DT_DMAS_LABEL_BY_IDX`, |
| :c:macro:`DT_DMAS_LABEL_BY_NAME`, |
| :c:macro:`DT_INST_DMAS_LABEL_BY_IDX`, and |
| :c:macro:`DT_INST_DMAS_LABEL_BY_NAME` were deprecated in favor of utilizing |
| :c:macro:`DT_DMAS_CTLR` and variants. |
| |
| * USB HID specific macros in ``<include/usb/class/usb_hid.h>`` are deprecated |
| in favor of new common HID macros defined in ``<include/usb/class/hid.h>``. |
| |
| * USB HID Kconfig option USB_HID_PROTOCOL_CODE is deprecated. |
| USB_HID_PROTOCOL_CODE does not allow to set boot protocol code for specific |
| HID device. USB HID API function usb_hid_set_proto_code() can be used instead. |
| |
| * USB HID class API is changed by removing get_protocol/set_protocol and |
| get_idle/set_idle callbacks. These callbacks are redundant or do not provide |
| any additional value and have led to incorrect usage of HID class API. |
| |
| * The ``CONFIG_OPENOCD_SUPPORT`` Kconfig option has been deprecated in favor |
| of ``CONFIG_DEBUG_THREAD_INFO``. |
| |
| * Disk drivers (``disk_access_*.c``) are moved to ``drivers/disk`` and renamed |
| according to their function. Driver's Kconfig options are revised and renamed. |
| SDMMC host controller drivers are selected when the corresponding node |
| in devicetree is enabled. Following application relevant Kconfig options |
| are renamed: ``CONFIG_DISK_ACCESS_RAM`` -> `CONFIG_DISK_DRIVER_RAM`, |
| ``CONFIG_DISK_ACCESS_FLASH`` -> `CONFIG_DISK_DRIVER_FLASH`, |
| ``CONFIG_DISK_ACCESS_SDHC`` -> `CONFIG_DISK_DRIVER_SDMMC`. |
| Disk API header ``<include/disk/disk_access.h>`` is deprecated in favor of |
| ``<include/storage/disk_access.h>``. |
| |
| * :c:func:`flash_write_protection_set()`. |
| |
| * The ``CONFIG_NET_CONTEXT_TIMESTAMP`` is removed as it was only able to work |
| with transmitted data. The same functionality can be achieved by setting |
| ``CONFIG_NET_PKT_RXTIME_STATS`` and ``CONFIG_NET_PKT_TXTIME_STATS`` options. |
| These options are also able to calculate the RX & TX times more accurately. |
| This means that support for the SO_TIMESTAMPING socket option is also removed |
| as it was used by the removed config option. |
| |
| * The device power management (PM) APIs and data structures have been renamed |
| from ``device_pm_*`` to ``pm_device_*`` since they are not device APIs but PM |
| subsystem APIs. The same applies to enumerations and definitions, they now |
| follow the ``PM_DEVICE_*`` convention. Some other API calls such as |
| ``device_set_power_state`` and ``device_get_power_state`` have been renamed to |
| ``pm_device_state_set`` and ``pm_device_state_get`` in order to align with |
| the naming of other device PM APIs. |
| |
| * The runtime device power management (PM) APIs is now synchronous by default |
| and the asynchronous API has the **_async** sufix. This change aligns the API |
| with the convention used in Zephyr. The affected APIs are |
| :c:func:`pm_device_put` and :c:func:`pm_device_get`. |
| |
| * The following functions, macros, and structures related to the kernel |
| work queue API: |
| |
| * :c:func:`k_work_pending()` replace with :c:func:`k_work_is_pending()` |
| * :c:func:`k_work_q_start()` replace with :c:func:`k_work_queue_start()` |
| * :c:struct:`k_delayed_work` replace with :c:struct:`k_work_delayable` |
| * :c:func:`k_delayed_work_init()` replace with |
| :c:func:`k_work_init_delayable` |
| * :c:func:`k_delayed_work_submit_to_queue()` replace with |
| :c:func:`k_work_schedule_for_queue()` or |
| :c:func:`k_work_reschedule_for_queue()` |
| * :c:func:`k_delayed_work_submit()` replace with :c:func:`k_work_schedule()` |
| or :c:func:`k_work_reschedule()` |
| * :c:func:`k_delayed_work_pending()` replace with |
| :c:func:`k_work_delayable_is_pending()` |
| * :c:func:`k_delayed_work_cancel()` replace with |
| :c:func:`k_work_cancel_delayable()` |
| * :c:func:`k_delayed_work_remaining_get()` replace with |
| :c:func:`k_work_delayable_remaining_get()` |
| * :c:func:`k_delayed_work_expires_ticks()` replace with |
| :c:func:`k_work_delayable_expires_get()` |
| * :c:func:`k_delayed_work_remaining_ticks()` replace with |
| :c:func:`k_work_delayable_remaining_get()` |
| * :c:macro:`K_DELAYED_WORK_DEFINE` replace with |
| :c:macro:`K_WORK_DELAYABLE_DEFINE` |

| Drivers and Sensors |
| ******************* |
| |
| * ADC |
| |
| * Added support on TI CC32xx. |
| * Added support on ITE IT8xxx2. |
| * Added support for DMA and HW triggers in the MCUX ADC16 driver. |
| * Added ADC emulator. |
| * Moved definitions of ADC acquisition time macros so that those macros can be used in dts files. |
| |
| * Bluetooth |
| |
| * The Kconfig option ``CONFIG_BT_CTLR_TO_HOST_UART_DEV_NAME`` was removed. |
| Use the :ref:`zephyr,bt-c2h-uart chosen node <devicetree-chosen-nodes>` |
| directly instead. |
| |
| * CAN |
| |
| * A driver for CAN-FD based on the Bosch M_CAN IP was added. The driver |
| currently supports STM32G4 series MCUs. Additional support for Microchip |
| SAM and NXP chips is in progress. |
| |
| * The CAN ISO-TP subsystem was enhanced to allow padding and fixed |
| addressing. |
| |
| * Clock Control |
| |
| * On STM32 series, system clock configuration has been moved from Kconfig to DTS. |
| Usage of existing Kconfig dedicated symbols (CONFIG_CLOCK_STM32_FOO) is now |
| deprecated. |
| |
| * Console |
| |
| * Added ``UART_CONSOLE_INPUT_EXPIRED`` and ``UART_CONSOLE_INPUT_EXPIRED_TIMEOUT`` |
| Kconfig options to notify the power management module that UART console is |
| in use now and forbid it to enter low-power states. |
| |
| * Counter |
| |
| * Added support for ESP32 Counter |
| |
| * DAC |
| |

| |
| * Added simulated PTP clock to e1000 Ethernet controller. This allows simple PTP |
| clock testing with Qemu. |
| * Separated PTP clock from gPTP support in mcux and gmac drivers. This allows |
| application to use PTP clock without enabling gPTP support. |
| * Converted clock control to use DEVICE_DT_GET in mcux driver. |
| * Changed to allow changing MAC address in gmac driver. |
| * Driver for STM32H7 is now using specific memory layout to fit DMA constraints |
| for RAM accesses. |
| |
| * Flash |
| |
| * flash_write_protection_set() has been deprecated and will be removed in |
| Zephyr 2.8. Responsibility for write/erase protection management has been |
| moved to the driver-specific implementation of the flash_write() and |
| flash_erase() API calls. All in-tree flash drivers have been updated, |
| and the protect implementation removed from their API tables. |
| During the deprecation period user code invoking |
| flash_write_protection_set() will have no effect, but the flash_write() and |
| flash_erase() driver shims will wrap their calls with calls to the protect |
| implementation if it is present in the API table. |
| Out-of-tree drivers must be updated before the wrapping in the shims is |
| removed when the deprecation period ends. |
| * Added QSPI support on STM32F7. |
| |
| * GPIO |
| |
| * :c:struct:`gpio_dt_spec`: a new structure which makes it more convenient to |
| access GPIO configuration in the :ref:`devicetree <dt-guide>`. |
| * New macros for initializing ``gpio_dt_spec`` values: |
| :c:macro:`GPIO_DT_SPEC_GET_BY_IDX`, :c:macro:`GPIO_DT_SPEC_GET_BY_IDX_OR`, |
| :c:macro:`GPIO_DT_SPEC_GET`, :c:macro:`GPIO_DT_SPEC_GET_OR`, |
| :c:macro:`GPIO_DT_SPEC_INST_GET_BY_IDX`, |
| :c:macro:`GPIO_DT_SPEC_INST_GET_BY_IDX_OR`, |
| :c:macro:`GPIO_DT_SPEC_INST_GET`, and :c:macro:`GPIO_DT_SPEC_INST_GET_OR` |
| * New helper functions for using ``gpio_dt_spec`` values: |
| :c:func:`gpio_pin_configure_dt`, :c:func:`gpio_pin_interrupt_configure_dt` |
| * Remove support for ``GPIO_INT_*`` flags in :c:func:`gpio_pin_configure()`. |
| The feature has been deprecated in the Zephyr 2.2 release. The interrupt |
| flags are now accepted by :c:func:`gpio_pin_interrupt_configure()` |
| function only. |

| ********** |
| |
| * CoAP: |
| |
| * Fixed coap_find_options() to return 0 when options are empty. |
| |
| * DHCPv4: |
| |
| * Fixed DHCPv4 dependency to network event management options. |
| |
| * DNS: |
| |
| * Added locking to DNS library prevent concurrent access. |
| * Added 10ms delay when rescheduling query timeout handler in DNS. This allows |
| applications to run and handle the timeout gracefully. |
| * Added support for reconfiguring DNS resolver when DNS servers are changed. |
| This is supported by DHCPv4 and PPP. |
| |
| * HTTP: |
| |
| * Added support for storing numeric HTTP error code in client API. |
| |
| * IPv4: |
| |
| * Added IGMPv2 support to IPv4. |
| * Removed IPv4 multicast address check when selecting source address during TX. |
| |
| * LwM2M: |
| |
| * Fixed query buffer size so that it is large enough to encode all query strings. |
| * Added data validation callback. |
| * Fixed Register/Update to use link_format writer. |
| * Added application/link-format content writer. |
| * Removed .well-known/core handling. |
| * Introduced attribute handling helper functions. |
| * Removed obsolete LWM2M_IPSO_TIMESTAMP_EXTENSIONS option. |
| * Added IPSO Buzzer, Push Button, On/Off Switch, Accelerometer, Pressure Sensor, |
| Humidity, Generic Sensor and Temperature object implementation to support |
| object model in version 1.1 |
| * Unified reusable resources creation. |
| * Added support for object versioning. |
| * Changed to allow cancel-observe to match path. |
| * Made pmin and pmax attributes optional. |
| * Added API function to delete object instance. |
| * Fixed Registration Update send on object creation. |
| * Changed to only parse TLV from the first block. |
| * Changed to trigger registration update only when registered. |
| |
| * Misc: |
| |
| * Added UDP packet sending support to net-shell. |
| * Fixed source network interface setting when sending and when there are |
| multiple network interfaces. |
| * Changed connection managed to ignore not used network interfaces. |
| * Added locking to network interface API function calls. |
| * Changed to allow application to disable IPv4 or IPv6 support for a network interface. |
| * Added support for virtual network interfaces. |
| * Added support for IPv4/v6 tunneling network interface. |
| * Added net events notification for PPP dead and running states. |
| * Added PPP LCP MRU option support. |
| * Added PPP IPCP IP and DNS address peer options support. |
| * Added support for network packet capturing and sending data to external system |
| for analysis. |
| * Enabled running without TX or RX threads. By default, one RX thread and |
| no TX thread is created. If userspace support is enabled, then one RX and one |
| TX thread are created. This improves the network transmit latency when a |
| packet is sent from application. |
| * Changed to push highest priority net_pkt directly to driver when sending and if |
| there is at least one TX thread. |
| * Changed to use k_fifo instead of k_work in RX and TX processing. This prevents |
| k_work from accessing already freed net_pkt struct. This also improves the latency |
| of network packets when the data is passed between different network threads. |
| * Changed to check network interface status when sending and return ENETDOWN to the |
| application if data cannot be sent. |
| * Fixed echo-server sample application and set netmask properly when VLAN is |
| enabled. |
| |
| * OpenThread: |
| |
| * Added microseconds timer API support. |
| * Changed to switch radio off when stopping diagnostics. |
| * Enabled CSL delayed transmissions. |
| * Added CSL transmitter and receiver API support. |
| * Changed to init NCP after USB communication is established. |
| * Aligned with the new NCP API. |
| * Aligned with the new CLI API. |
| * Introduced new OpenThread options. |
| * Added Link Metrics API support. |
| * Selected ECDSA when SRP is enabled. |
| * Made child related options only visible on FTD. |
| * Changed OT shell not to execute OT commands when shell is not ready. |
| |
| * Socket: |
| |
| * Added SO_PROTOCOL and SO_TYPE get socket option. |
| * Added MSG_WAITALL receive socket option flag. |
| * Added MSG_TRUNC socket option flag. |
| * Added support for close method for packet sockets. |
| * Added locking to socket API function calls. |
| * Added support for SO_BINDTODEVICE socket option. |
| * Added support for SO_SNDTIMEO socket option. |
| * Made NET_SOCKETS_POSIX_NAMES be on by default. This allows application to use |
| normal BSD socket API calls without adding the zsock prefix. |
| * Added sample application to use SO_TXTIME socket option. |
| |
| * TCP: |
| |
| * Implemented ISN calculation according to RFC6528 in TCP. This is optional and |
| enabled by default, and can be disabled if needed. |
| * Removed legacy TCP stack support. |
| * Changed TCP to use private work queue in order not to block system work queue. |
| |
| * TLS: |
| |
| * Fixed userspace access to TLS socket. |
| * Added socket option support for setting and getting DTLS handshake timeout. |

| Build and Infrastructure |
| ************************ |
| |
| * Improved support for additional toolchains: |
| * Support for the Intel oneApi toolchain. |
| |
| * Devicetree |
| |
| - :c:macro:`DT_COMPAT_GET_ANY_STATUS_OKAY`: new macro |
| - the ``96b-lscon-3v3`` and ``96b-lscon-1v8`` :ref:`compatible properties |
| <dt-important-props>` now have ``linaro,`` vendor prefixes, i.e. they are |
| now respectively :dtcompatible:`linaro,96b-lscon-3v3` and |
| :dtcompatible:`linaro,96b-lscon-1v8`. |
| |
| This change was made to bring Zephyr's devicetrees into compliance with an |
| upstream Linux regular expression used to validate compatible properties. |
| This regular expression requires a letter as the first character. |
| |
| * West (extensions) |
| |
| * This section only covers west :ref:`west-extensions` maintained in the |
| zephyr repository. For release notes on west's built-in features, see |
| :ref:`west-release-notes`. |
| |
| * Changes to the runners backends used for :ref:`flashing and debugging |
| commands <west-build-flash-debug>`: |
| |
| * bossac runner: added legacy mode option into extended SAM-BA |
| bootloader selection. This extends compatibility between Zephyr and |
| some Arduino IDE bootloaders. |
| |
| * jlink runner: Zephyr thread awareness is now available in GDB by default |
| for application builds with :option:`CONFIG_DEBUG_THREAD_INFO` set to ``y`` |
| in :ref:`kconfig`. This applies to ``west debug``, ``west debugserver``, |
| and ``west attach``. JLink version 7.11b or later must be installed on the |
| host system, with JLink 7.20 or later strongly recommended. |
| |
| * jlink runner: default ``west flash`` output is less verbose. The old |
| behavior is still available when run as ``west --verbose flash``. |
| |
| * jlink runner: when flashing, this runner now prefers a ``.hex`` file |
| generated by the build system to a ``.bin``. Unlike ``.bin``, the HEX |
| format includes information on the image's address range in flash, so |
| this works better when flashing Zephyr images linked for locations other |
| than the target's boot address, e.g. images meant to be run by |
| bootloaders. The ``.bin`` file is still used as a fallback if a HEX File |
| is not present. |
| |
| * openocd runner: support for ``west debug`` and ``west attach`` has been |
| fixed. Previously with this runner, ``west debug`` behaved like ``west |
| attach`` should, and ``west attach`` behaved like ``west debugserver`` |
| should. |
| |
| * pyocd runner: board-specific pyOCD configuration files in YAML can now be |
| placed in :file:`support/pyocd.yaml` inside the board directory. See |
| :zephyr_file:`boards/arm/reel_board/support/pyocd.yaml` for an example, |
| and the pyOCD documentation for details on its configuration format. |
| |
| * ``west spdx``: new command which can be used to generate SPDX software |
| bills of materials for a Zephyr application build. See :ref:`west-spdx`. |

| * POSIX subsystem |
| |
| * Power management |
| |
| * ``device_pm_control_nop`` has been removed in favor of ``NULL`` when device |
| PM is not supported by a device. In order to make transition easier for |
| out-of-tree users a macro with the same name is provided as an alias to |
| ``NULL``. The macro is flagged as deprecated to make users aware of the |
| change. |
| |
| * Devices set as busy are no longer suspended by the system power management. |
| |
| * The time necessary to exit a sleep state and return to the active state was |
| added in ``zephyr,power-state`` binding and accounted when the system |
| changes to a power state. |
| |
| * Device runtime power management (PM), former IDLE runtime, was |
| completely overhauled. |
| |
| * Multiple threads can wait an operation (:c:func:`pm_device_get_async` and |
| :c:func:`pm_device_put_async`) to finish. |
| * A new API :c:func:`pm_device_wait` was added so that drivers can easily |
| wait for an async request to finish. |
| * The API can be used in :ref:`pre-kernel <api_term_pre-kernel-ok>` stages. |
| * Several concurrence issues related with atomics access and the usage |
| of the polling API have been fixed. Condition variables are now used to |
| handle notification. |
| |
| * Logging |
| |
| * Introduced logging v2 which allows logging any variable types (including |
| floating point variables). New version does not require transient string |
| duplication (``log_strdup()``). Legacy mode remains and is still the default |
| but user API is not changed and modes are interchangeable. |
| ``CONFIG_LOG2_MODE_DEFERRED`` or ``CONFIG_LOG2_MODE_IMMEDIATE`` enable |
| logging v2. Logging backend API is extended to support v2 and the most |
| popular backends (UART, shell) are updated. |
| |
| * LVGL |
| |
| * Shell |
| |
| * Storage |
| |
| * Task Watchdog |
| |
| * This new subsystem was added with this release and allows supervision of |
| individual threads. It is based on a regularly updated kernel timer, |
| whose ISR is never actually called in regular system operation. |
| |
| An existing hardware watchdog can be used as an optional fallback if the |
| task watchdog itself gets stuck. |
| |
| * Tracing |
| |
| * ``CONFIG_TRACING_CPU_STATS`` was removed in favor of |
| ``CONFIG_THREAD_RUNTIME_STATS`` which provides per thread statistics. The |
| same functionality is also available when Thread analyzer is enabled with |
| the runtime statistics enabled. |
| * Expanded and overhauled tracing hooks with more coverage and support for |
| tracing all kernel objects and basic power management operations. |
| * Added support for Percepio Tracealyzer, a commercial tracing tool which now |
| has built-in support for Zephyr. We now have the Percepio tracerecorder |
| integrated as a module. |
| * Expanded support for the new hooks in SEGGER Systemview and enhanced the |
| description file with support for all APIs. |
| |
| * Debug |
| * SEGGER Systemview and RTT SDK updated to version v3.30 |
| |
| * OS |
| |
| * Reboot functionality has been moved to ``subsys/os`` from ``subsys/power``. |
| A consequence of this movement is that the ``<power/reboot.h>`` header has |
| been moved to ``<sys/reboot.h>``. ``<power/reboot.h>`` is still provided |
| for compatibility, but it will produce a warning to inform users of the |
| relocation. |
| |
| HALs |
| **** |
| |
| * HALs are now moved out of the main tree as external modules and reside in |
| their own standalone repositories. |
| |
| |
| Trusted Firmware-m |
| ****************** |
| |
| * Synchronized Trusted-Firmware-M module to the upstream v1.3.0 release. |
| * Configured QEMU to run Zephyr samples and tests in CI on mps2_an521_nonsecure |
| (Cortex-M33 Non-Secure) with TF-M as the secure firmware component. |
| * Added Kconfig options for selecting the desired TF-M profile and build type |
| * Added Kconfig options for enabling the desired TF-M secure partitions |
| * Added a new sample to run the PSA tests with Zephyr |
| * Added a new sample to run the TF-M regression tests using the Zephyr build system |
| * Added support for new platforms |
| |
| * BL5340 DVK |
| * STM32L562E DK |
| |
| * NOTE: Trusted-Firmware-M can not currently be used with mbedtls 2.26.0 when |
| PSA APIs are enabled in mbedtls (``MBEDTLS_USE_PSA_CRYPTO`` and |
| ``MBEDTLS_PSA_CRYPTO_C``). If both TF-M and mbedtls are required, mbedtls |
| must be used without the PSA APIs. This will be resolved in a future |
| update to mbedtls. |
| |
| Documentation |
| ************* |
| |
| * Documentation look and feel has been improved by using a new stylesheet. |
| * Doxygen is now run by Sphinx using the ``doxyrunner`` custom extension. The |
| new extension centralizes multiple scattered workarounds that existed before |
| in a single place. |
| * Doxygen now runs with ``WARN_AS_ERROR`` enabled. |
| * Documentation known warnings are now filtered using a custom Sphinx extension: |
| ``warnings_filter``. This extension removes the need of post-processing |
| the Sphinx output and allows to use the ``-W`` option (treat warnings as |
| errors) which has been enabled by default. |
| * External content, e.g. samples and boards documentation is now handled by |
| the ``external_content`` extension. |
| * Sphinx is now run in parallel mode by default (``-j auto``). |
| * The documentation helper ``Makefile`` has been moved from the repository root |
| to the ``doc`` folder. |
| |
| Tests and Samples |
| ***************** |
| |
| * Twister's ``dt_compat_enabled_with_alias()`` test case filter was deprecated |
| in favor of a new ``dt_enabled_alias_with_parent_compat()`` filter. The old |
| filter is still supported, but it may be removed in a future release. |
| |
| To update, replace uses like this: |
| |
| .. code-block:: yaml |
| |
| filter: dt_compat_enabled_with_alias("gpio-leds", "led0") |
| |
| with: |
| |
| .. code-block:: yaml |
| |
| filter: dt_enabled_alias_with_parent_compat("led0", "gpio-leds") |
| |
| * Add a feature which handles pytest script in twister and provide an example. |
| * Provide test excution time per ztest testcase. |
| * Added and refined some testcases, most of them are negative testcases, to |
| improve the test code coverage: |
| |
| * Testcases of x86's regular/direct interrupts and offload job from ISR. |
| * Testcases of SMP, and enabled SMP for existed testing of semaphore, condvar, etc. |
| * Testcases of memory protection, userspace and memory heap. |
| * Testcases of data structure include stack, queue, ringbuffer and rbtree. |
| * Testcases of IPC include pipe, poll, mailbox, message queue. |
| * Testcases of synchronization include mutex, semaphore, atomic operations. |
| * Testcases of scheduling and thread. |
| * Testcases of testing for arch_nop() and errno. |
| * Testcases of libc and posix API. |
| * Testcases of log and sensor subsystem. |
