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 through 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 parameter 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.

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.

  • 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.
