| Cortex-M(etal): Hyper-optimized Zephyr-Friendly Context Switching for a Mature Architecture | Zephyr Developer Summit 2025 | 2025-08-25 |
A rewrite replaces the Cortex‑M PendSV heavy path with an inline, stack‑only context frame and a 17‑instruction resume sequence written in Thumb‑2 assembly… | ||
| Cortex-M(etal): Hyper-optimized Zephyr-Friendly Context Switching for a Mature Architecture | Open Source Summit Europe 2025 | 2025-08-25 |
Reworks the Cortex‑M context‑switch to a stack‑centric frame implemented as 17 thumb2 instructions (not yet Cortex‑M0 compatible), lands in a PR and shows a… | ||
| Inter Process Confusion - Navigating Zephyr's IPC APIs | Zephyr Developer Summit @ Embedded Open Source Summit 2024 | 2024-04-16 |
Zephyr gives concrete primitives and tradeoffs: k_sem is tiny and uncontended operations cost about a dozen cycles, threads are expensive (expect ~4K stack… | ||
| Inter Process Confusion - Navigating Zephyr's IPC APIs | Embedded Open Source Summit 2024 | 2024-04-16 |
Zephyr offers many overlapping IPC primitives and that abundance causes poor choices; semaphores are the low‑cost default for locking and short waits, km… | ||
