| Dynamic vCPU priority boosting in KVM for latency sensitive workloads | Linux Plumbers Conference 2023 | 2023-11-13 |
A prototype for x86_64 implements host–guest communication using shared memory and hypercalls so the guest signals latency intent and the host temporarily… | ||
| Fixing Real-Time Scheduler Throttling in the Linux Kernel | LinuxCon @ OSS NA 2023 | 2023-05-10 |
Problem: Linux RT throttling is too aggressive for ChromeOS/Android workloads, starving UI threads while leaving CPUs idle. Kernel changes keep throttled RT… | ||
| Make RCU do less (save power)! | Linux Plumbers Conference 2022 | 2022-09-12 |
Default RCU keeps the scheduler tick firing during idle and generates thousands of tiny wakes (2500/sec observed), which suppresses deep package C‑states and… | ||
| Make RCU do less (and disturb CPUs less)! | Linux Plumbers Conference 2022 | 2022-09-12 |
RCU activity keeps timers awake and prevents deep CPU idle, with graphics FDs queuing callbacks every ~16 ms and single-callback wakeups causing wasted… | ||
| Debugging Methodologies for Realtime Issues in Linux Systems | Embedded Linux Conference + OpenIoT Summit Europe 2016 | 2016-10-11 |
Shows how to find and fix real latency sources using concrete tools and fixes: uses irqsoff tracer and function_graph tracer to spot top-half handlers and… | ||
