Re: Zephyr 1.14.0 Released (corrected)
All,toggle quoted messageShow quoted text
In my rush to get 1.14 released, I reported on the Major Enhancements from 1.13. Sorry for the confusion. Here is the corrected list of Major Enhancements in 1.14:
* The Zephyr project now supports over 160 different board configurations
spanning 8 architectures. All architectures are rigorously tested and
validated using one of the many simulation platforms supported by the
project: QEMU, Renode, ARC Simulator, and the native POSIX configuration.
* The timing subsystem has been reworked and reimplemented, greatly
simplifying the resulting drivers, removing thousands of lines
of code, and reducing a typical kernel build size by hundreds of bytes.
TICKLESS_KERNEL mode is now the default on all architectures.
* The Symmetric Multi-Processing (SMP) subsystem continues to evolve
with the addition of a new CPU affinity API that can "pin" threads to
specific cores or sets of cores. The core kernel no longer uses the
global irq_lock on SMP systems, and exclusively uses the spinlock API
(which on uniprocessor systems reduces to the same code).
* Zephyr now has support for the x86_64 architecture. It is currently
implemented only for QEMU targets, supports arbitrary numbers of CPUs,
and runs in SMP mode by default, our first platform to do so.
* We've overhauled the Network packet (net-pkt) API and moved the majority
of components and protocols to use the BSD socket API, including MQTT,
CoAP, LWM2M, and SNTP.
* We enhanced the native POSIX port by adding UART, USB, and display
drivers. Based on this port, we added a simulated NRF52832 SoC which enables
running full system, multi-node simulations, without the need of real
* We added an experimental BLE split software Controller with Upper Link Layer
and Lower Link Layer for supporting multiple BLE radio hardware
* The power management subsystem has been overhauled to support device idle
power management and move most of the power management logic from the
application back to the BSP.
* We introduced major updates and an overhaul to both the logging and
shell subsystems, supporting multiple back-ends, integration
of logging into the shell, and delayed log processing.
* Introduced the `west` tool for management of multiple repositories and
enhanced support for flashing and debugging.
* Added support for application user mode, application memory
partitions, and hardware stack protection in ARMv8m
* Applied MISRA-C code guideline on the kernel and core components of Zephyr.
MISRA-C is a well established code guideline focused on embedded systems and
aims to improve code safety, security and portability.
