| Zephyr Kernel 2.0.0 (Working Draft) |
| #################################### |
| |
| We are pleased to announce the release of Zephyr kernel version 2.0.0. |
| |
| Major enhancements with this release include: |
| |
| * The kernel now supports both 32- and 64-bit architectures. |
| * We added support for SOCKS5 proxy. SOCKS5 is an Internet protocol that |
| exchanges network packets between a client and server through a proxy server. |
| * Introduced support for 6LoCAN, a 6Lo adaption layer for Controller Area |
| Networks. |
| * We added support for :ref:`Point-to-Point Protocol (PPP) <ppp>`. PPP is a |
| data link layer (layer 2) communications protocol used to establish a direct |
| connection between two nodes. |
| * We added support for UpdateHub which is an end-to-end solution for large scale |
| over-the-air update of devices. |
| * We added support for ARM Cortex-R Architecture (EXPERIMENTAL). |
| |
| The following sections provide detailed lists of changes by component. |
| |
| Kernel |
| ****** |
| |
| * New kernel API for per-thread disabling of Floating Point Services for |
| ARC, ARM Cortex-M, and x86 architectures. |
| |
| Architectures |
| ************* |
| |
| * ARM: |
| |
| * Added initial support for ARM Cortex-R architecture (EXPERIMENTAL) |
| * We enhanced the support for Floating Point Services in Cortex-M |
| architecture, implementing and enabling lazy-stacking for FPU |
| capable threads and fixing stack overflow detection for FPU |
| capable supervisor threads |
| * Added Qemu support for ARMv8-M Mainline architecture |
| * Optimized the IRQ locking time in thread context switch |
| * Fixed several critical bugs in User Mode implementation |
| * Added test coverage for ARM-specific kernel features |
| * Improved support for linking TrustZone Secure Entry functions into |
| Non-Secure firmware |
| |
| |
| * POSIX: |
| |
| * Fix race condition with terminated threads which had never been |
| scheduled by kernel. On very loaded systems it could cause swap errors. |
