| OF-nodes, Fwnodes, Swnodes, Devlinks, Properties - Understanding How Devices... | Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 | 2025-12-08 |
Recap of kernel device modeling from C board files through Device Tree and ACPI into a unified firmware node API, explanation of software nodes and secondary… | ||
| Give Me Back My GPIO Persistence Intro to the libgpiod GPIOManager | Embedded Linux Conference Europe 2024 | 2024-09-16 |
Kernel-side GPIO persistence is rejected so userspace implements it: a new gpio-manager daemon (merged to master and planned for libgpiod 2.2) runs as a… | ||
| Give Me Back My GPIO Persistence Intro to the libgpiod GPIOManager | Open Source Summit Europe 2024 | 2024-09-16 |
Claim is that kernel persistence is rejected so a user‑space daemon solves it: libgpiod now includes gpio-manager, a two‑year effort merged to master and… | ||
| Compound Interest - Dealing with Two Decades of Technical Debt in Embedded... | Embedded Linux Conference @ EOSS NA 2024 | 2024-04-16 |
GPIO has two in-kernel APIs, two uAPI variants and decades of quirks tied to ARM board files, and about 35% still use the old numeric interface. The core claim… | ||
| BoF: Object Life-Time Handling in Driver Subsystems | Embedded Linux Conference @ EOSS NA 2024 | 2024-04-16 |
Many driver subsystems crash when provider data goes away; gpio gets an SRCU-backed split responsibility solution where the subsystem allocates the… | ||
| BoF: Object Life-Time Handling in Driver Subsystems | Embedded Open Source Summit 2024 | 2024-04-16 |
Device driver subsystems frequently crash when provider drivers free their per-driver memory while consumers still hold references; the concrete fix here is to… | ||
| Compound Interest - Dealing with Two Decades of Technical Debt in Embedded... | Embedded Open Source Summit 2024 | 2024-04-16 |
GPIO subsystem accumulates two decades of legacy: a dual in-kernel API, two uAPIs and 35% still use the old number-based ABI. Serialization and sleeping vs… | ||
| Improving resource ownership and life-time in linux device drivers | Linux Plumbers Conference 2023 | 2023-11-13 |
Many subsystems mix reference‑counted resources with regular data and embed implementation structs inside driver private data, leading to use‑after‑free and… | ||
| libgpiod V2: New Major Release with a Ton of New Features | Linux Plumbers Conference 2022 | 2022-09-12 |
libgpiod v2 implements a redesigned user API: immutable line info snapshots, separated request config vs line config to avoid reconfigure mistakes, per-request… | ||
| Libgpiod V2: New Major Release with a Ton of New Features | Embedded Linux Conference @ Open Source Summit North America 2022 | 2022-06-21 |
Libgpiod v2 reworks the C API into opaque objects, implements the new kernel character-device v2 features (per-line sequence numbers, configurable debounce and… | ||
| Plan to Throw One Away Pitfalls of API Design for Low-level User-space Libraries & Kernel Interfaces | Open Source Summit + Embedded Linux Conference + OSPOCon 2021 | 2021-09-27 |
libgpiod and the GPIO character device evolve because v1 locks in struct layouts and APIs that users later demand to extend; after four years a v2 branch adds… | ||
| Early Platform Drivers in Linux Kernel | Open Source Summit Europe & ELC + OpenIoT Summit Europe 2018 | 2018-10-22 |
Proposes a lightweight early platform driver framework that lets OF_DECLARE users register devices that run an early_probe callback very early and then get… | ||
| New GPIO Interface for User Space | Open Source Summit Europe + Embedded Linux Conference Europe 2017 | 2017-10-23 |
Linux deprecates the GPIO sysfs interface (since v4.8) in favor of a GPIO character device that lets user space open a chip, request up to 64 lines at once… | ||
