| rtla timerlat: Debugging Real-Time Linux Scheduling Latency | Real-Time Linux Summit 2024 | 2024-04-16 |
rtla timerlat is a kernel+userspace tool that measures and traces scheduling latency, decomposes spikes into irq, RQ and thread components, and produces a… | ||
| Real-Time Linux: What Is Next? | Real-Time Linux Summit 2024 | 2024-04-16 |
PREEMPT_RT work is essentially upstream now after an eight‑year effort with $5.7M raised and many features like high‑res timers, tracing and threaded IRQs… | ||
| rtla timerlat: Debugging Real-Time Linux Scheduling Latency | Embedded Open Source Summit 2024 | 2024-04-16 |
rtla timerlat is a kernel + userland tool that measures and traces scheduling latency with a few microseconds of overhead (minimum ~2 µs) and can stop and dump… | ||
| Real-Time Linux: What Is N... | Embedded Open Source Summit 2024 | 2024-04-16 |
PREEMPT_RT is largely upstream now after about $5.7M raised and years of backports work; high-resolution timers, tracing and threaded IRQs already mainline and… | ||
| Welcome message and DL Server | Linux Plumbers Conference 2023 | 2023-11-13 |
A patch set implements a DL server that uses SCHED_DEADLINE to schedule an entire fair scheduler so FIFO/RT busy loops cannot starve CFS tasks, replacing… | ||
| RTLA Requests and TODOs | Linux Plumbers Conference 2023 | 2023-11-13 |
RTLA is a set of user-space binaries that measure scheduling latency and root‑cause it: a timerlot sampler flags latencies over ~30 µs and breaks them into… | ||
| rtla timerlat: Debugging Real-time Linux Scheduling Latency | Embedded Linux Conference (ELC) @ EOSS 2023 | 2023-06-27 |
rtla timerlat integrates a kernel tracer and a user-space front end to measure and decompose scheduling latency into IRQ vs thread split… | ||
| RTLA Timerlat - the next step in scheduling latency analysis | Real Time Linux Summit @ Embedded Open Source Summit 2023 | 2023-06-26 |
RTLA Timerlat is a combined kernel + userland tool that measures IRQ and thread latency split by doing most computation in-kernel to avoid excessive trace… | ||
| RV: where are we? | Linux Plumbers Conference 2022 | 2022-09-12 |
Runtime verification (RV) is now merged in mainline (6.0) as a tracing-based subsystem that runs automata as per-CPU C monitors generated by the tool dot2k… | ||
| rtla: what is next? | Linux Plumbers Conference 2022 | 2022-09-12 |
rtla provides a usable interface for kernel latency tracers and already ships a timerlat tracer that measures IRQ and thread latency (similar to cyclictest)… | ||
| rtla osnoise: what is missing? | Linux Plumbers Conference 2022 | 2022-09-12 |
An rtla/osnoise tracer runs a per-CPU busy-loop tracer that detects latency spikes by comparing time reads against a threshold, then correlates each spike with… | ||
| RTLA: Real-time Linux Analysis Toolset | Embedded Linux Conference @ Open Source Summit North America 2022 | 2022-06-21 |
RTLA ships kernel tracers (os_noise since 5.14, userland tool since 5.17) plus a C user-space front end that automates expert workflows, runs rtla os-noise and… | ||
| A Maintainable, Scalable, and Verifiable SW Qualification Approach for Automotive in Linux | Open Source Summit + Embedded Linux Conference + OSPOCon 2021 | 2021-09-27 |
Proposes a hybrid qualification approach that treats drivers or subsystems as ISO 26262 pre‑existing components (part 8.12) and verifies their integration with… | ||
| Real-time Linux: what is next? | DevConf.CZ 2021 | 2021-02-18 |
PREEMPT_RT is mainlined but work continues: a scheduling-latency formal model maps kernel events to variables and yields a pessimistic worst-case bound; a… | ||
| May the Trust be with You: Empowering TrustZone-M with Multiple Trusted Environments | Black Hat Asia 2020 | 2020-09-29 |
Claim: TrustZone‑M’s dual-world model is too big and brittle, so a new microkernel splits an MCU into isolated multiple trusted worlds. Implementation: a 6 KB… | ||
| SCHED_DEADLINE desiderata and slightly crazy ideas | DevConf.CZ 2020 | 2020-01-24 |
Describes missing and in-development work for SCHED_DEADLINE: an RFC and patches for pressure inheritance to let mutex owners execute with donors’… | ||
| Formal Verification Made Easy (and fast!) | Open Source Summit Europe + Embedded Linux Conference Europe 2019 | 2019-10-28 |
Modeling PREEMPT_RT as synchronised automata produces a runnable verifier that moves from offline traces to an in-kernel checker translated from the formal… | ||
