Zephyr 3.1.0

The following sections provide detailed lists of changes by component.

API Changes

Changes in this release

  • All Zephyr public headers have been moved to include/zephyr, meaning they need to be prefixed with <zephyr/...> when included. Because this change can potentially break many applications or libraries, CONFIG_LEGACY_INCLUDE_PATH is provided to allow using the old include path. This option is now enabled by default to allow a smooth transition. In order to facilitate the migration to the new include prefix, a script to automate the process is also provided: scripts/utils/migrate_includes.py.

  • LoRaWAN: The message type parameter in lorawan_send() was changed from uint8_t to enum lorawan_message_type. If 0 was passed for unconfirmed message, this has to be changed to LORAWAN_MSG_UNCONFIRMED.

  • Bluetooth: Applications where CONFIG_BT_EATT is enabled must set the chan_opt field on the GATT parameter structs. To keep the old behavior use BT_ATT_CHAN_OPT_NONE.

  • Disk Subsystem: SPI mode SD cards now use the SD subsystem to communicate with SD cards. See the disk access api for an example of the new devicetree binding format required.

  • Kconfig preprocessor function dt_nodelabel_has_compat was redefined, for consistency with the dt_nodelabel_has_prop function and devicetree macros like DT_NODE_HAS_COMPAT(). Now the function does not take into account the status of the checked node. Its former functionality is provided by the newly introduced dt_nodelabel_enabled_with_compat function.

  • CAN

Removed APIs in this release

  • STM32F1 Serial wire JTAG configuration (SWJ CFG) configuration choice was moved from Kconfig to devicetree. See the st,stm32f1-pinctrl devicetree binding for more information. As a consequence, the following Kconfig symbols were removed:

    • CONFIG_GPIO_STM32_SWJ_ENABLE

    • CONFIG_GPIO_STM32_SWJ_NONJTRST

    • CONFIG_GPIO_STM32_SWJ_NOJTAG

    • CONFIG_GPIO_STM32_SWJ_DISABLE

  • Removed experimental 6LoCAN protocol support.

  • Removed the following deprecated CAN APIs:

    • Custom CAN error codes

    • can_configure()

    • can_attach_workq()

    • can_attach_isr()

    • can_attach_msgq()

    • can_detach()

    • can_register_state_change_isr()

    • can_write()

    • The bt_l2cap_chan_state values BT_L2CAP_CONNECT and BT_L2CAP_DISCONNECT have been renamed to BT_L2CAP_CONNECTING and BT_L2CAP_DISCONNECTING respectively.

    • The callbacks pairing_complete(), pairing_failed(), and bond_delete() have been moved from struct bt_auth_cb to a newly created informational-only callback struct bt_conn_auth_info_cb.

    • bt_conn_index() now takes a const struct bt_conn* argument.

    • The bt_gatt_subscribe_params structure’s write callback function has been deprecated. Use the new subscribe callback instead.

    • bt_disable() was added to enable the caller to disable the Bluetooth stack.

    • Added new Kconfig options to select ISO Central and Peripheral role support separately

    • Added a new bt_get_appearance() API call

    • Implemented support for dynamic appearance, including a new bt_set_appearance() API call

    • Implemented support for L2CAP collision mitigation

    • Changed the scheduling of auto-initiated HCI commands so that they execute synchronously

    • Added a new bt_is_ready() API call to find out if Bluetooth is currently enabled and initialized

    • Added support for automatic MTU exchange right after a connection is established

    • Created a new bt_conn_auth_info_cb to group the security-related callbacks under a single struct

    • Optimized the memory usage of the Object Transfer Service

    • Added a new bt_hci_le_rand() API call to obtain a random number from the LE Controller

    • Added a new public API to connect EATT channels, bt_eatt_connect()

    • Optimized L2CAP channels resource usage when not using dynamic channels

    • Added the ability to run the Bluetooth RX context from a workqueue, in order to optimize RAM usage. See CONFIG_BT_RECV_CONTEXT.

    • Added support for TX complete callback on EATT channels

    • Corrected the calling of the MTU callback to happen on any reconfiguration

Kernel

  • Aborting an essential thread now causes a kernel panic, as the documentation has always promised but the kernel has never implemented.

  • The k_timer handler can now correct itself for lost time due to very late-arriving interrupts.

  • SMP interprocessor interrupts are deferred so that they are sent only at schedule points, and not synchronously when the scheduler state changes. This prevents IPI “storms” with code that does many scheduler operations at once (e.g. waking up a bunch of threads).

  • The timeslicing API now allows slice times to be controlled independently for each thread, and provides a callback to the app when a thread timeslice has expired. The intent is that this will allow apps the tools to implement CPU resource control algorithms (e.g. fairness or interactivity metrics, budget tracking) that are out of scope for Zephyr’s deterministic RTOS scheduler.

Architectures

  • x64_64

    • UEFI devices can now use the firmware-initialized system console API as a printk/logging backend, simplifying platform bringup on devices without known-working serial port configurations.

    • STM32L5: Added support for Single Bank.

    • STM32 QSPI driver was extended with with QER (SFDP, DTS), custom quad write opcode and 1-1-4 read mode.

    • Added support for STM32U5 series.

  • GPIO

    • Refactored GPIO devicetree flags. The upper 8 bits of gpio_dt_flags_t are now reserved for controller/SoC specific flags. Certain hardware-specific flags previously defined as common configuration (IO voltage level, drive strength, and debounce filter) were replaced with ones defined in this controller/SoC specific space.

    • Added Xilinx PS MIO/EMIO GPIO controller driver.

    • Extended the NXP PCA95XX driver to support also PCAL95XX.

  • HWINFO

    • Atmel SAM: Added RSTC support

    • Fixed Atmel SAM/SAM0 exclusive bus access

    • Added ITE support

  • I2S

    • Ported I2S drivers to pinctrl.

    • Fixed multiple bugs in the NXP I2S (SAI) driver, including problems with DMA transmission and FIFO under/overruns.

  • MEMC

    • STM32: Extended FMC driver to support NOR/PSRAM. See st,stm32-fmc-nor-psram.yaml.

  • Pin control

    • Platform support was added for:

      • Atmel SAM/SAM0

      • Espressif ESP32

      • ITE IT8XXX2

      • Microchip XEC

      • Nordic nRF (completed support)

      • Nuvoton NPCX Embedded Controller (EC)

      • NXP iMX

      • NXP Kinetis

      • NXP LPC

      • RV32M1

      • SiFive Freedom

      • Telink B91

      • TI CC13XX/CC26XX

    • STM32: It is now possible to configure plain GPIO pins using the pinctrl API. See st,stm32-pinctrl and st,stm32f1-pinctrl for more information.

  • PWM

    • Added pwm_dt_spec and associated helpers, e.g. PWM_DT_SPEC_GET or pwm_set_dt(). This addition makes it easier to use the PWM API when the PWM channel, period and flags are taken from a devicetree PWM cell.

    • STM32: Enabled complementary output for timer channel. A PWM consumer can now use PWM_STM32_COMPLEMENTARY to specify that PWM output should happen on a complementary channel pincfg (eg:tim1_ch2n_pb14).

    • STM32: Added counter mode support. See st,stm32-timers.

    • Aligned nRF PWM drivers (pwm_nrfx and pwm_nrf5_sw) with the updated PWM API. In particular, this means that the pwm_set() and pwm_set_cycles() functions need to be called with a PWM channel as a parameter, not with a pin number like it was for the deprecated pwm_pin_set_* functions. Also, the flags parameter is now supported by the drivers, so either the PWM_POLARITY_INVERTED or PWM_POLARITY_NORMAL flag must be provided in each call.

  • Reset

    • Added reset controller driver API.

    • Raspberry Pi Pico: Added reset controller driver

  • Sensor

    • Added NCPX ADC comparator driver.

  • USB

    • Added RP2040 (Raspberry Pi Pico) USB device controller driver

Networking

  • CoAP:

    • Changed coap_pending allocation criteria. This now uses a data pointer instead of a timestamp, which does not give a 100% guarantee that structure is not in use already.

  • Ethernet:

  • HTTP:

    • Removed a limitation where the maximum content length was limited up to 100000 bytes.

    • Fixed http_client_req() return value. The function now correctly reports the number of bytes sent.

    • Clarified the expected behavior in case of empty response from the server.

    • Made use of shutdown to tear down HTTP connection instead of closing the socket from a system work queue.

  • LwM2M:

    • Various improvements towards LwM2M 1.1 support:

      • Added LwM2M 1.1 Discovery support.

      • Added attribute handling for Resource Instances.

      • Added support for Send, Read-composite, Write-composite, Observe-composite operations.

      • Added new content formats: SenML JSON, CBOR, SenML CBOR.

      • Added v1.1 implementation of core LwM2M objects.

    • Added support for dynamic Resource Instance allocation.

    • Added support for LwM2M Portfolio object (Object ID 16).

    • Added LwM2M shell module.

    • Added option to utilize DTLS session cache in queue mode.

    • Added lwm2m_engine_path_is_observed() API function.

    • Fixed a bug with hostname verification setting, which prevented DTLS connection in certain mbedTLS configurations.

    • Fixed a bug which could cause a socket descriptor leak, in case lwm2m_rd_client_start() was called immediately after lwm2m_rd_client_stop().

    • Added error reporting from lwm2m_rd_client_start() and lwm2m_rd_client_stop().

  • Misc:

    • Added net_if_set_default() function which allows to set a default network interface at runtime.

    • Added CONFIG_NET_DEFAULT_IF_UP option which allows to make the first interface which is up the default choice.

    • Fixed packet leak in network shell TCP receive handler.

    • Added net_pkt_rx_clone() which allows to allocated packet from correct packet pool when cloning. This is used at the loopback interface.

    • Added CONFIG_NET_LOOPBACK_SIMULATE_PACKET_DROP option which allows to simulate packet drop at the loopback interface. This is used by certain test cases.

  • MQTT:

    • Removed custom logging macros from MQTT implementation, in favour of the common networking logging.

  • OpenThread:

    • Updated OpenThread revision up to commit 130afd9bb6d02f2a07e86b824fb7a79e9fca5fe0.

    • Implemented otPlatCryptoRand platform API for OpenThread.

    • Added support for PSA MAC keys.

    • Multiple minor fixes/improvements to align with upstream OpenThread changes.

  • Sockets:

    • Added support for shutdown() function.

    • Fixed sendmsg() operation when TCP reported full transmission window.

    • Added support for getpeername() function.

    • Fixed userspace accept() argument validation.

    • Added support for SO_SNDBUF and SO_RCVBUF socket options.

    • Implemented POLLOUT reporting from poll() for STREAM sockets.

    • Implemented socket dispatcher for offloaded sockets. This module allows to use multiple offloaded socket implementations at the same time.

    • Introduced a common socket priority for offloaded sockets (CONFIG_NET_SOCKETS_OFFLOAD_PRIORITY).

    • Moved socket offloading out of experimental.

  • TCP:

    • Implemented receive window handling.

    • Implemented zero-window probe processing and sending.

    • Improved TCP stack throughput over loopback interface.

    • Fixed possible transmission window overflow in case of TCP retransmissions. This could led to TX buffer starvation when TCP entered retransmission mode.

    • Updated FIN_TIMEOUT delay to correctly reflect time needed for all FIN packet retransmissions.

    • Added proper error reporting from TCP to upper layers. This solves the problem of connection errors being reported to the application as graceful connection shutdown.

    • Added a mechanism which allows upper layers to monitor the TCP transmission window availability. This allows to improve throughput greatly in low-buffer scenarios.

  • TLS:

USB

  • Moved USB device stack code to own directory in preparation for upcoming rework of USB support.

Build System

  • The build system’s internals have been completely overhauled for increased modularity. This makes it easier to reuse individual components through the Zephyr CMake package mechanism.

    With the improved Zephyr CMake package, the following examples are now possible:

    • find_package(Zephyr): load a standard build system, as before

    • find_package(Zephyr COMPONENTS unittest): load a specific unittest build component

    • find_package(Zephyr COMPONENTS dts): only load the dts module and its direct dependencies

    • find_package(Zephyr COMPONENTS extensions west zephyr_module): load multiple specific modules and their dependencies

    Some use cases that this work intends to enable are:

    • The sysbuild proposal: Zephyr sysbuild / multi image #40555

    • Running Zephyr CMake configure stages individually. One example is only processing the devicetree steps of the build system, while skipping the rest. This is a required feature for extending twister to do test case filtering based on the devicetree contents without invoking a complete CMake configuration.

    For more details, see cmake/package_helper.cmake.

  • A new Zephyr SDK has been created which now supports macOS and Windows in addition to Linux platforms.

    For more information, see: https://github.com/zephyrproject-rtos/sdk-ng

Devicetree

Libraries / Subsystems

  • C Library

    • Minimal libc

      • Added [U]INT_{FAST,LEAST}N_{MIN,MAX} minimum and maximum value macros in stdint.h.

      • Added PRIx{FAST,LEAST}N and PRIxMAX format specifier macros in inttypes.h.

      • Fixed gmtime() access fault when userspace is enabled and gmtime() is called from a user mode thread. This function can be safely called from both kernel and user mode threads.

    • Newlib

      • Fixed access fault when calling the newlib math functions from a user mode thread. All libm.a globals are now placed into the z_libc_partition when userspace is enabled.

  • C++ Subsystem

    • Renamed all C++ source and header files to use the cpp and hpp extensions, respectively. All Zephyr upstream C++ source and header files are now required to use these extensions.

  • Management

    • MCUMGR has been migrated from using TinyCBOR, for CBOR encoding, to zcbor.

    • MCUMGR CONFIG_FS_MGMT_UL_CHUNK_SIZE and CONFIG_IMG_MGMT_UL_CHUNK_SIZE have been deprecated as, with the introduction of zcbor, it is no longer needed to use an intermediate buffer to copy data out of CBOR encoded buffer. The file/image chunk size is now limited by CONFIG_MCUMGR_BUF_SIZE minus all the other command required variables.

    • Added support for MCUMGR Parameters command, which can be used to obtain MCUMGR parameters; CONFIG_OS_MGMT_MCUMGR_PARAMS enables the command.

    • Added mcumgr fs handler for getting file status which returns file size; controlled with CONFIG_FS_MGMT_FILE_STATUS

    • Added mcumgr fs handler for getting file hash/checksum, with support for IEEE CRC32 and SHA256, the following Kconfig options have been added to control the addition:

    • Added mcumgr os hook to allow an application to accept or decline a reset request; CONFIG_OS_MGMT_RESET_HOOK enables the callback.

    • Added mcumgr fs hook to allow an application to accept or decline a file read/write request; CONFIG_FS_MGMT_FILE_ACCESS_HOOK enables the feature which then needs to be registered by the application.

    • Added supplied image header to mcumgr img upload callback parameter list which allows the application to inspect it to determine if it should be allowed or declined.

    • Made the img_mgmt_vercmp() function public to allow application- level comparison of image versions.

    • mcumgr will now only return MGMT_ERR_ENOMEM when it fails to allocate a memory buffer for request processing, when previously it would wrongly report this error when the SMP response failed to fit into a buffer; now when encoding of response fails MGMT_ERR_EMSGSIZE will be reported. This addresses issue 44535.

    • Added CONFIG_IMG_MGMT_USE_HEAP_FOR_FLASH_IMG_CONTEXT that allows user to select whether the heap will be used for flash image context, when heap pool is configured. Previously usage of heap has been implicit, with no control from a developer, causing issues reported by 44214. The default, implicit, behaviour has not been kept and the above Kconfig option needs to be selected to keep previous behaviour.

  • SD Subsystem

    • Added the SD subsystem, which is used by the disk access api to interact with connected SD cards. This subsystem uses the SDHC api to interact with the SD host controller the SD device is connected to.

  • Power management

  • IPC

    • static_vrings: Fixed work queue (WQ) initialization

    • static_vrings: Introduced atomic helpers when accessing atomic_t variables

    • static_vrings: Moved to one WQ per instance

    • static_vrings: Added “zephyr,priority” property in the DT to set the WQ priority of the instance

    • static_vrings: Added configuration parameter to initialize shared memory to zero

    • Extended API with NOCOPY functions

    • static_vrings: Added support for NOCOPY operations

    • Introduced inter core messaging backend (icmsg) that relies on simple inter core messaging buffer

  • Logging

    • Added UART frontend which supports binary dictionary logging.

    • Added support for MIPI SyS-T catalog messages.

    • Added cAVS HDA backend.

  • Removed deprecated DT_CHOSEN_ZEPHYR_FLASH_CONTROLLER_LABEL.

  • Fixed usage of CONFIG_LOG_IMMEDIATE.

Trusted Firmware-m

  • Updated to TF-M 1.6.0

Documentation

  • Reorganised and consolidated documentation for improved readability and user experience.

  • Replaced the existing statically rendered Kconfig documentation with the new Kconfig documentation engine that dynamically renders the Kconfig contents for improved search performance.

  • Added a ‘Language Support’ sub-category under the ‘Developing with Zephyr’ category that provides details regarding C and C++ language and standard library support status.

  • Added a ‘Toolchain’ sub-category under the ‘Developing with Zephyr’ category that lists all supported toolchains along with instructions for how to configure and use them.

Tests and Samples

  • A dedicated framework was added to test the STM32 clock_control driver.
