| Do nothing fast: How to scale idle cpus? | Linux Plumbers Conference 2023 | 2023-11-13 |
A global raw spinlock in the idle path and a small delay loop during do_idle unexpectedly speeds a scheduler-heavy hackbench on a 192-core AMD EPYC, taking the… | ||
| 60 Adaptive userspace spinlocks with rseq | Linux Plumbers Conference 2023 | 2023-11-13 |
Proposes exposing thread run state to userspace via rseq so userspace can do cheap, syscall-free checks and only spin when the lock owner is actually running… | ||
| Restartable Sequences: Scheduler-Aware Scaling of Memory Use on Many-Core Systems | Linux Plumbers Conference 2022 | 2022-09-12 |
Patches implement a per-memory-space virtual CPU ID and per-mm bitmaps plus a small runqueue vcpu cache so scheduler assigns short-lived IDs without global… | ||
| Restartable Sequences: Scaling Per-Core Shared Memory Use in Containers | Linux Plumbers Conference 2022 | 2022-09-12 |
Proposal extends restartable sequences with a new per-memory-space vcpu ID field so shared memory users allocate arrays sized to container-visible CPUs instead… | ||
| Tracer namespaces | Linux Plumbers Conference 2022 | 2022-09-12 |
Proposes attaching per-namespace ring buffers so each container namespace gets its own ring and events are serialized into buffers up the hierarchy via… | ||
