Zephyr 2.4.0
############

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.

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
  :ref:`experimental stability <api_lifecycle>`. See :ref:`util_api` for an API
  reference.

* The :c:func:`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.
  :c:type:`uart_callback_t` and :c:type:`uart_irq_callback_user_data_t`
  had their signature changed to add a struct device pointer as first parameter.
  :c:type:`uart_irq_callback_t` has been removed. :c:func:`uart_callback_set`,
  :c:func:`uart_irq_callback_user_data_set` and :c:func:`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.
  :c:type:`ipm_callback_t` had its signature changed to add a struct device
  pointer as first parameter. :c:func:`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 :c:func:`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 :c:func:`bt_gatt_attr_func_t` used by
  :c:func:`bt_gatt_foreach_attr` and :c:func:`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
    :ref:`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.

    in the cs-gpios devicetree properties rather than the
    SPI_CS_ACTIVE_LOW/HIGH configuration options.  Devicetree files that
    specify 0 for this field will probably need to be updated to specify
    GPIO_ACTIVE_LOW.  SPI_CS_ACTIVE_LOW/HIGH are still used for chip
    selects that are not specified by a cs-gpios property.
  * Added driver for the Xilinx AXI Quad SPI IP.

    sample.
  * Added support for the Nordic nRF52805 IC.
  * Several fixes to scheduling and window calculation, some of which had an
    impact in the cooperation between the flash driver and the Controller.
  * Fixed an null pointer dereference in the ticker code.

* HCI Driver

  * A new BT_QUIRK_NO_AUTO_DLE has been added for Controllers that do not follow
    the recommendation of auto-initating the data length update procedure. This
    is in fact the case of the split software Controller.

Build and Infrastructure
************************

* Improved support for additional toolchains:

  * Better toolchain abstractions.
  * Support for the ARC MetaWare toolchain.

* Devicetree

  * Added new devicetree macros that provide a default value if the property
    or cell accessor doesn't contain the requested data.

  * Added support for inferring bindings for ``/zephyr,user`` devicetree node
    to allow applications an easy way to specify application specific
    devicetree properties without having a binding.

* Support for multiple SOC and ARCH roots.
  The :ref:`SOC_ROOT <application>` and ``ARCH_ROOT`` variables used to specify
  support files for out of tree SoCs and architectures now accept multiple
  paths, separated by semicolons. As a result, the ``SOC_DIR`` Kconfig variable
  is no longer supported.

  Uses like ``source $(SOC_DIR)/<path>`` must be changed to
  ``rsource <relative>/<path>`` or similar.

* BOARD, SOC, DTS, and ARCH roots can now be specified in each module's
  :file:`zephyr/module.yml` file; see :ref:`modules_build_settings`.

Libraries / Subsystems
**********************

* Disk

* Management

  * MCUmgr

    * Moved mcumgr into its own directory.
    * UDP port switched to using kernel stack.
    * smp: added missing socket close in error path.

  * Added support for Open Supervised Device Protocol (OSDP), see :kconfig:option:`CONFIG_OSDP`.

  * updatehub

    * Added download block check.
    * Added support to flash integrity check using SHA-256 algorithm.
    * Moved updatehub from lib to subsys/mgmt directory.
    * Fixed out-of-bounds access and add flash_img_init return value check.
    * Fixed getaddrinfo resource leak.

* Settings

  * If a setting read is attempted from a channel that doesn't support reading return an error rather than faulting.
  * Disallow modifying the content of a static subtree name.

* Random

* POSIX subsystem

* Power management

* Logging

  * Fixed immediate logging with multiple backends.
  * Switched logging thread to use kernel stack.
  * Allow users to disable all shell backends at one using :kconfig:option:`CONFIG_SHELL_LOG_BACKEND`.
  * Added Spinel protocol logging backend.
  * Fixed timestamp calculation when using NEWLIB.

* LVGL

  * Library has been updated to the new major release v7.0.2.

  * It is important to note that v7 introduces multiple API changes and new
    configuration settings, so applications developed on v6 or previous versions
    will likely require some porting work. Refer to `LVGL 7 Release notes
    <https://github.com/lvgl/lvgl/releases/tag/v7.0.0>`_ for more information.

  * LVGL Kconfig option names have been aligned with LVGL. All LVGL
    configuration options ``LV_[A-Z0-9_]`` have a matching Zephyr Kconfig
    option named as ``CONFIG_LVGL_[A-Z0-9_]``.

  * LVGL Kconfig constants have been aligned with upstream suggested defaults.
    If your application relies on any of the following Kconfig defaults consider
    checking if the new values are good or they need to be adjusted:

    * :kconfig:option:`CONFIG_LVGL_HOR_RES_MAX`
    * :kconfig:option:`CONFIG_LVGL_VER_RES_MAX`
    * :kconfig:option:`CONFIG_LVGL_DPI`
    * :kconfig:option:`CONFIG_LVGL_DISP_DEF_REFR_PERIOD`
    * :kconfig:option:`CONFIG_LVGL_INDEV_DEF_READ_PERIOD`
    * :kconfig:option:`CONFIG_LVGL_INDEV_DEF_DRAG_THROW`
    * :kconfig:option:`CONFIG_LVGL_TXT_LINE_BREAK_LONG_LEN`
    * :kconfig:option:`CONFIG_LVGL_CHART_AXIS_TICK_LABEL_MAX_LEN`

  * Note that ROM usage is significantly higher on v7 for minimal
    configurations. This is in part due to new features such as the new drawing
    system. LVGL maintainers are currently investigating ways for reducing the
    library footprint when some options are not enabled, so you should wait for
    future releases if higher ROM usage is a concern for your application.

* Shell

  * Switched to use kernel stacks.
  * Fixed select command.
  * Fixed prompting dynamic commands.
  * Change behavior when more than ``CONFIG_SHELL_ARGC_MAX`` arguments are
    passed.  Before 2.3 extra arguments were joined to the last argument.
    In 2.3 extra arguments caused a fault.  Now the shell will report that
    the command cannot be processed.

* Storage

  * Added flash SHA-256 integrity check.

* Tracing

  * Tracing backed API now checks if init function exists prio to calling it.

* Debug

  * Core Dump

    * Added the ability to do core dump when fatal error is encountered.
      This allows dumping the CPU registers and memory content for offline
      debugging.
    * Cortex-M, x86, and x86-64 are supported in this release.
    * A data output backend utilizing the logging subsystem is introduced
      in this release.

HALs
****

* HALs are now moved out of the main tree as external modules and reside in
  their own standalone repositories.
