| I3C, the Industry, and Linux | Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 | 2025-12-08 |
I3C promises higher speed and dynamic addressing and mostly delivers: normal transfers and dynamic address assignment work, but clock stretching fails and hot… | ||
| Object Lifetime Issues - a Threat for Safety? | Critical Software Summit @ Open Source Summit Japan 2023 | 2023-12-05 |
Research shows longstanding object lifetime bugs in kernel subsystems cause real failures: a reproduced MTD crash in QEMU (kernel 6.7-rc4) and blocking I2C… | ||
| Subsystems with Object Lifetime Issues (in the Embedded Case) | Embedded Linux Conference (ELC) @ EOSS 2023 | 2023-06-27 |
Claim: embedding a struct device inside driver-private structs and allocating the wrapper with devm_kzalloc always wrong in this context lets a platform remove… | ||
| Lessons Learned When Updating Userspace ABIs | LinuxCon Europe 2022 | 2022-09-13 |
SMBus block limit changes from 32 to 255 bytes and exposes a userspace ABI problem where a fixed union and ioctl numbers are UAPI stable so old userland vs new… | ||
| Linux I2C in the 21st Century | Open Source Summit Europe + Embedded Linux Conference Europe 2019 | 2019-10-28 |
Modern Linux I2C adds concrete features: runtime client address reprogramming for multiplexed media devices to avoid collisions, core API changes to support… | ||
| DMA Safety in Buffers for Linux Kernel Device Drivers | Open Source Summit Europe & ELC + OpenIoT Summit Europe 2018 | 2018-10-22 |
Work on I2C finds that externally supplied message buffers are often not DMA-safe, so an opt-in DMA_SAFE flag and a small helper API now exist that either… | ||
| More Robust I2C Designs with a New Fault-Injection Driver | Open Source Summit Europe + Embedded Linux Conference Europe 2017 | 2017-10-23 |
A new GPIO-based fault injection driver that sits on the same lines as the I2C master and intentionally toggles SDA/SCL to force real error paths is… | ||
| Trying to Explain the 'Incomprehensible' Decision Making Process of a Subsystem Maintainer | Embedded Linux Conference + OpenIoT Summit Europe 2016 | 2016-10-11 |
I2C maintainership faces scaling: accepted patches per cycle rise from ~2,000 (v3.0) to ~14,000 (v4.8) while backlog grows exponentially, not chronologically… | ||
| Maintainer_s Diary - We Have a Scaling Problem | Embedded Linux Conference Europe 2013 | 2013-10-24 |
Kernel contributions grow fast while reviewer capacity lags, creating a scaling problem: about 200 new authors versus only 200 committers, and the gap widens… | ||
| Maintaining a kernel subsystem | FOSDEM 2013 | 2013-02-02 |
...at least how I do it
This talk provides some insight how Wolfram handles the I2C subsystem of the Linux kernel, which is one puzzle piece which simply has… | ||
