Zephyr v2.4.0

We are pleased to announce the release of Zephyr RTOS version 2.4.0.

Major enhancements with this release include:

• Introduced initial support for virtual memory management.

• Added Bluetooth host support for periodic advertisement and isochronous
  channels.

• Enabled the new TCP stack, TCP2, by default. This stack was introduced in
  Zephyr v2.1.0 to improve network protocol testability with open source tools.

• Introduced a new toolchain abstraction with initial implementations for GCC
  and LLVM/Clang, and groundwork for future support of commercial toolchains.

• Moved to using C99 integer types and deprecate Zephyr integer types. The
  Zephyr types can be enabled by Kconfig DEPRECATED_ZEPHYR_INT_TYPES option.

The following sections provide detailed lists of changes by component.

Known issues

You can check all currently known issues by listing them using the GitHub
interface and listing all issues with the bug label.

API Changes

• Moved to using C99 integer types and deprecate Zephyr integer types. The
  Zephyr types can be enabled by Kconfig DEPRECATED_ZEPHYR_INT_TYPES option.

• The <sys/util.h> header has been promoted to a documented API with
  experimental stability. See util_api for an API
  reference.

• The wdt_feed function will now return -EAGAIN if
  issuing a feed would stall the caller. Application code may need to
  ignore this diagnostic result or initiate another feed operation
  later.

• <drivers/uart.h> has seen its callbacks normalized.
  uart_callback_t and uart_irq_callback_user_data_t
  had their signature changed to add a struct device pointer as first parameter.
  uart_irq_callback_t has been removed. uart_callback_set,
  uart_irq_callback_user_data_set and uart_irq_callback_set
  user code have been modified accordingly.

• <drivers/dma.h> has seen its callback normalized. It had its signature
  changed to add a struct device pointer as first parameter. Such callback
  signature has been generalized throuh the addition of dma_callback_t.
  'callback_arg' argument has been renamed to 'user_data. All user code have
  been modified accordingly.

• <drivers/ipm.h> has seen its callback normalized.
  ipm_callback_t had its signature changed to add a struct device
  pointer as first parameter. ipm_register_callback user code have
  been modified accordingly. The context argument has been renamed to user_data
  and all drivers have been modified against it as well.

• The fs_open function now accepts open flags that are passed as
  a third parameter.
  All custom file system front-ends require change to the implementation
  of open callback to accept the new parameter.
  To maintain original behaviour within user code, two argument invocations
  should be converted to pass a third argument FS_O_CREATE | FS_O_RDWR.

• The struct device got 3 attributes renamed: config_info to config,
  driver_api to api and finally driver_data to data.
  This renaming was done to get rid of legacy names, for which the reasons
  do no longer apply.

• All device instances got a const qualifier. So this applies to all APIs
  manipulating struct device * (ADC, GPIO, I2C, ...). In order to avoid
  const qualifier loss on ISRs, all ISRs now take a const *void as a
  paremeter as well.

• The _gatt_ and _GATT_ infixes have been removed for the HRS, DIS
  and BAS APIs and the Kconfig options.

• <include/bluetooth/gatt.h> callback bt_gatt_attr_func_t used by
  bt_gatt_foreach_attr and bt_gatt_foreach_attr_type has
  been changed to always pass the original pointer of attributes along with its
  resolved handle.

• Established the unrestricted alignment of flash reads for all drivers.

Deprecated in this release

• The full set of k_mem_pool and sys_mem_pool APIs
  are considered deprecated as of this release. The replacements are
  the k_heap and sys_heap APIs. These APIs are not tagged with
  __deprecated in the 2.4 release, but will be in 2.5. They will be
  removed completely in Zephyr 2.6 LTS. The set of APIs now deprecated is as
  follows:

  • k_mbox_data_block_get()
  • k_pipe_block_put()
  • K_MEM_POOL_DEFINE()
  • k_mem_pool_alloc()
  • k_mem_pool_free()
  • k_mem_pool_free_id()
  • SYS_MEM_POOL_DEFINE()
  • sys_mem_pool_init()
  • sys_mem_pool_alloc()
  • sys_mem_pool_free()
  • sys_mem_pool_try_expand_inplace()

• The Kconfig option CONFIG_MULTITHREADING to disable multi-threading was
  deprecated due to lack of maintainership. This means that single-threaded
  mode with the scheduler disabled is deprecated; normal multi-threaded mode is
  still fully supported.

Removed APIs in this release

• Other

  • The deprecated MACRO_MAP macro has been removed from the
    util_api. Use FOR_EACH instead.
  • The CONFIG_NET_IF_USERSPACE_ACCESS is removed as it is no longer needed.

• Build system

  • The set of *_if_kconfig() CMake functions have been removed. Use
    _ifdef(CONFIG_ ...) instead.

Stable API changes in this release

• USB

  • HID class callbacks now takes a parameter const struct device* which
    is the HID device for which callback was called.

• Bluetooth

  • The _gatt_ infix has been removed from all GATT service APIs.

• Bluetooth HCI Driver

  • bt_hci_evt_is_prio() removed, use bt_hci_evt_get_flags() instead when
    CONFIG_BT_RECV_IS_RX_THREAD is defined and call bt_recv and bt_recv_prio
    when their flag is set, otherwise always call bt_recv().

Kernel

• Initial support for virtual memory management

  • API definitions in include/sys/mem_manage.h.
  • Supporting architectures will implement arch_mem_map() and enable
    CONFIG_MMU.
  • The kernel is linked at its physical memory location in RAM.
  • The size of the address space is controlled via CONFIG_KERNEL_VM_SIZE
    with memory mapping calls allocating virtual memory growing downward
    from the address space limit towards the system RAM mappings.
  • This infrastructure is still under heavy development.

• Device memory mapped I/O APIs

  • Namedspaced as DEVICE_MMIO and specified in a new
    include/sys/device_mmio.h header.

  • This is added to facilitate the specification and the storage location of
    device driver memory-mapped I/O regions based on system configuration.

    • Maintained entirely in ROM for most systems.
    • Maintained in RAM with hooks to memory-mapping APIs for MMU or PCI-E
      systems.

• Updates for Memory Domain APIs

  • All threads now are always a member of a memory domain. A new
    memory domain k_mem_domain_default introduced for initial threads
    like the main thread.
  • The k_mem_domain_destroy() and k_mem_domain_remove_thread() APIs
    are now deprecated and will be removed in a future release.
  • Header definitions moved to include/app_memory/mem_domain.h.

• Thread stack specification improvements

  • Introduced a parallel set of K_KERNEL_STACK_* APIs for specifying
    thread stacks that will never host user threads. This will conserve memory
    as ancillary data structures (such as privilege mode elevation stacks) will
    not need to be created, and certain alignment requirements are less strict.

  • Internal interfaces to the architecture code have been simplified. All
    thread stack macros are now centrally defined, with arches declaring
    support macros to indicate the alignment of the stack pointer, the
    stack buffer base address, and the stack buffer size.

Architectures

• ARC

  • Added ARC MetaWare toolchain support
  • General arch improvements for stacks & memory domains
  • API improvements for cache flush and cache invalidate
  • Debugging help: show all registers on exception
  • Fix for fast irq (one register bank configuration)
  • Fix for undefined shift behavior (CID 211523)

• ARM

  • AARCH32

    • Added support for ARM Cortex-M1 architecture.
    • Implemented the timing API in Cortex-M architecture using the Data
      Watchpoint and Trace (DWT) unit.
    • The interrupt vector relaying feature support was extended to Cortex-M
      Mainline architecture variants.
    • Cortex-M fault handling implementation was enhanced by adding an option to
      generate and supply the full register state to the kernel fatal error
      handling mechanism.
    • Fixed Cortex-M boot sequence for single-threaded applications
      (CONFIG_MULTITHREADING=n).
    • Added thread safety to Non-Secure entry function calls in ARMv8-M
      architecture.
    • Fixed stack randomization for main thread.
    • Fixed exception vector table alignment in Cortex-M architecture
    • Increased test coverage in QEMU for ARMv6-M architecture variant.
    • Removed the implementation of arch_mem_domain_* APIs for Cortex-M

  • AARCH64

Zephyr v2.3.0

We are pleased to announce the release of Zephyr RTOS version 2.3.0.

Major enhancements with this release include:

• A new Zephyr CMake package has been introduced, reducing the need for
  environment variables
• A new Devicetree API, based on hierarchical macros, has been introduced. This
  new API allows the C code to access virtually all nodes and properties in a
  clean, organized fashion
• The kernel timeout API has been overhauled to be flexible and configurable,
  with future support for features like 64-bit and absolute timeouts in mind
• A new k_heap/sys_heap heap allocator has been introduced, with much better
  performance than the existing k_mem_pool/sys_mem_pool
• Zephyr now integrates with the TF-M (Trusted Firmware M) PSA-compliant
  framework
• The Bluetooth Low Energy Host now supports LE Advertising Extensions
• The CMSIS-DSP library is now included and integrated

The following sections provide detailed lists of changes by component.

Known issues

You can check all currently known issues by listing them using the GitHub
interface and listing all issues with the bug label.

A single high-priority bug is currently open:

• #23364 - Bluetooth: bt_recv deadlock on supervision timeout with
  pending GATT Write Commands

API Changes

• HWINFO

  • The identifier data structure for hwinfo drivers is clarified. Drivers are
    responsible for ensuring that the identifier data structure is a sequence
    of bytes. The returned ID value is not supposed to be interpreted based on
    vendor-specific assumptions of byte order and should express the identifier
    as a raw byte sequence.
    The changes have an impact on users that use the hwinfo API to identify
    their devices.
    The sam0 driver byte swaps each 32 bit word of the 128 bit identifier to
    big endian.
    The nordic driver byte swaps the entire 64 bit word to big endian.

• I2C

  • Added a new API for recovering an I2C bus from situations where the I2C
    master and one or more I2C slaves are out of synchronization (e.g. if the
    I2C master was reset in the middle of an I2C transaction or if a noise
    pulse was induced on the SCL line).

Deprecated in this release

• Kernel

  • k_uptime_delta_32(), use k_uptime_delta()

  • Timeout values

    • All timeout values are now encapsulated k_timeout_t opaque structure when
      passing them to the kernel. If you want to revert to the previous s32_t
      type for the timeout parameter, please enable
      :option:CONFIG_LEGACY_TIMEOUT_API

• Bluetooth

  • BT_LE_SCAN_FILTER_DUPLICATE, use BT_LE_SCAN_OPT_FILTER_DUPLICATE instead
  • BT_LE_SCAN_FILTER_WHITELIST, use BT_LE_SCAN_OPT_FILTER_WHITELIST instead
  • bt_le_scan_param::filter_dup, use bt_le_scan_param::options instead
  • bt_conn_create_le(), use bt_conn_le_create() instead
  • bt_conn_create_auto_le(), use bt_conn_le_create_auto() instead
  • bt_conn_create_slave_le(), use bt_le_adv_start() instead with
    bt_le_adv_param::peer set to the remote peers address.
  • BT_LE_ADV_* macros, use BT_GAP_ADV_* enums instead

• Boards

  • nrf51_pca10028 has been renamed to nrf51dk_nrf51422
  • nrf51_pca10031 has been renamed to nrf51dongle_nrf51422
  • nrf52810_pca10040 has been renamed to nrf52dk_nrf52810
  • nrf52_pca10040 has been renamed to nrf52dk_nrf52832
  • nrf52833_pca10100 has been renamed to nrf52833dk_nrf52833
  • nrf52811_pca10056 has been renamed to nrf52840dk_nrf52811
  • nrf52840_pca10056 has been renamed to nrf52840dk_nrf52840
  • nrf52840_pca10059 has been renamed to nrf52840dongle_nrf52840
  • nrf9160_pca10090 has been renamed to nrf9160dk_nrf9160
  • nrf52840_pca10090 has been renamed to nrf9160dk_nrf52840
  • nrf52_pca20020 has been renamed to thingy52_nrf52832
  • nrf5340_dk_nrf5340 has been renamed to nrf5340pdk_nrf5340
  • efr32_slwstk6061a has been renamed to efr32_radio_brd4250b

• Devicetree

  • The C macros generated from the devicetree in previous releases are now
    deprecated in favor of a new <devicetree.h> API.
  • See :ref:dt-from-c for a high-level guide to the new API, and
    :ref:devicetree_api for an API reference.
  • Use of the legacy macros now requires explicitly enabling
    :option:CONFIG_LEGACY_DEVICETREE_MACROS. See :ref:dt-legacy-macros for
    more information, including a link to a migration guide to the new API.

• Other

  • MACRO_MAP has been deprecated. Use FOR_EACH instead.
  • BUILD_ASSERT_MSG has been deprecated. Use BUILD_ASSERT instead.

Removed APIs in this release

• The INLINE macro in util.h has been removed.
• STACK_ANALYZE, stack_analyze and stack_unused_space_get have been
  removed.

Stable API changes in this release

• Bluetooth Mesh

  • The net_idx parameter has been removed from the Health Client model
    APIs since it can be derived (by the stack) from the app_idx parameter

• Networking

  • The NET_DEVICE_INIT(), NET_DEVICE_INIT_INSTANCE(), NET_DEVICE_OFFLOAD_INIT()
    and ETH_NET_DEVICE_INIT() macros changed and take a device power management
    function pointer parameter. If networking PM is not implemented for the
    specific network device, the device_pm_control_nop value can be used.

• Video

  • The video_dequeue() API call now takes a k_timeout_t for the timeout
    parameter. This reverts to s32_t if CONFIG_LEGACY_TIMEOUT_API is enabled.

• Floating Point Services

  • FLOAT and FP_SHARING Kconfig options have been renamed to FPU and FPU_SHARING,
    respectively.

Kernel

• A new general purpose memory allocator, sys_heap/k_heap, has been added
  to Zephyr with more conventional API/behavior, better space
  efficiency and higher performance than the pre-existing mem_pool.
  The older mem_pool APIs are, by default, wrappers around this new
  heap backend and will be deprecated in an upcoming release. The
  original implementation remains available for this release via
  disabling CONFIG_MEM_POOL_HEAP_BACKEND.
• The timeout arguments to all kernel calls are now a "k_timeout_t"
  type instead of a 32 bit millisecond count. These can be
  initialized in arbitrary time units (ns/us/ms, ticks), be
  interpreted relative to either current time or system start, and be
  expressed in 64 bit quantities. This involves a minor change to the
  API, so the original API is still available in a completely
  source-compatible way via CONFIG_LEGACY_TIMEOUT_API.
• Simplified dummy thread implementation and properly name idle threads
• Centralized new thread priority check
• Refactored device structures and introduced struct init_entry which is
  a generic init end-point. SYS_INIT() generates only a struct init_entry via
  calling INIT_ENTRY_DEFINE(). Also removed struct deviceconfig leaving
  struct device to own everything now.

Architectures

• ARC:

  • Changed to automatic generation of privilege stack for ARC MPU V2 to
    avoid the potential waste of memory When USERSPACE is configured
  • Enhanced runtime programming for the MPU v3 by making the gap-filling
    of kernel memory a user-configurable feature
  • Refactored the thread switch code in epilogue of irq and exception
  • Refactored the assembly codes for better maintenance
  • Fixed the behavior of ARC timer driver
  • Fixed the behavior of ARC SMP
  • Fixed the wrong configurations of ARC boards in Kconfig and DTS

• ARM:

  • CMSIS has been moved out of the main tree and now resides in its
    own standalone module repository
  • Updated CMSIS version to 5.7.0
  • Added CMSIS-DSP library integration
  • Added semihosting console support
  • Cleanups and improvements to the Cortex-M exception vector table
  • Fixed the behavior of Cortex-M spurious IRQ handler
  • Fixed parsing of Cortex-M MemManage Stacking Errors
  • Fixed the arch_cpu_idle() implementation for Cortex-M and Cortex-R
  • Renamed Cortex-R architecture port to cortex_a_r in preparation for the
    AArch32 Cortex-A architecture port
  • Added processor exception handling and reporting framework for Cortex-R
  • Added nested interrupt support on AArch32 Cortex-R and AArch64 Cortex-A
  • Refactored Cortex-R interrupt system to remove fake multi-level interrupt
    controller abstraction scheme

• POSIX:

  • Added support for building on ARM hosts

• RISC-V:

  • Added support for hard floating point for RISC-V
  • Added march and mabi options to Kconfig
  • Fixed compilation warning for platforms without PLIC

• x86:

  • Instrumented code for timing information
  • Added ability for SoC to add MMU regions
  • x86 FPU sharing symbols renam...
