| ##################### |
| |
| We are pleased to announce the release of Zephyr kernel version 1.11.0. |
| |
| Major enhancements with this release include: |
| |
| * Thread-level memory protection on x86, ARC and Arm, userspace and memory |
| domains |
| * Symmetric Multi Processing (SMP) support on the Xtensa architecture. |
| * Initial Armv8-M architecture support. |
| * Native development environment on Microsoft Windows. |
| * Native build target on POSIX platforms. |
| * POSIX PSE52 partial support. |
| * Thread support via integration with OpenThread. |
| * Firmware over-the-air (FOTA) updates over BLE using MCUmgr. |
| * Lightweight flash storage layer for constrained devices. |
| * Additional SoC, platform and driver support for many of the already supported |
| platforms. |
| |
| The following sections provide detailed lists of changes by component. |
| |
| Kernel |
| ****** |
| |
| * Initial Symmetric Multi Processing (SMP) support added: |
| |
| * SMP-aware scheduler |
| * SMP timer and idling support |
| * Available on the Xtensa architecture |
| * POSIX PSE52 support: |
| |
| * Timer, clock, scheduler and pthread APIs |
| |
| Architectures |
| ************* |
| |
| * User space and system call related changes: |
| |
| * Added ARC user space implementation |
| * Added Arm user space implementation |
| * Fixed a few MPU related issues with stack guards |
| * Armv8-M initial architecture support, including the following cores: |
| |
| * Arm Cortex-M23 |
| * Arm Cortex-M33 |
| * New POSIX architecture for native GNU/Linux and macOS build targets: |
| |
| * Targets native executables that can be run on the host operating system |
| |
| Boards |
| ****** |
| |
| * New native_posix board for the POSIX architecture: |
| |
| * Includes a template for hardware models |
| * Adds support for console and logging |
| * Interrupts and timers are simulated in several different configurations |
| * Added support for the following Arm boards: |
| |

| * stm32f072b_disco |
| * Removed Panther board support, which included boards/x86/panther and |
| boards/arc/panther_ss |
| * Refactored dts.fixup so common SoC-related fixes are in arch/<*>/soc |
| and board dts.fixup is only used for board-specific items. |
