| uprobe optimization and override | Linux Plumbers Conference 2025 | 2025-12-11 |
Kernel now implements an x86-only uprobe optimization that replaces a five‑byte NOP probe with a user‑space trampoline and uprobe syscall, avoiding exception… | ||
| Where have all the kprobes gone | Linux Plumbers Conference 2023 | 2023-11-13 |
Many BPF-attached tracing probes silently drop execution because different attach layers enforce different re-entry checks and some layers never exported miss… | ||
| State of kprobes/trampolines batch attachment | Linux Plumbers Conference 2022 | 2022-09-12 |
Kernel adds a fast batch attach path for kprobes using ftrace: a new kpro_multi link and register_fprobe wrapper let one syscall attach a BPF program to many… | ||
| perf build IDs | DevConf.CZ 2021 | 2021-02-18 |
New perf flow stores build ids in the kernel memory map events so perf record skips the slow post-processing and no longer needs perf archive; perf report or… | ||
| ebpf iterators | DevConf.CZ 2021 | 2021-02-18 |
eBPF iterators let users dump kernel objects (tasks, files, maps, BPF programs, network objects) by opening and reading a file backed by an iterator; programs… | ||
| bpftrace internals | DevConf.CZ 2020 | 2020-01-24 |
Explains exactly how bpftrace compiles scripts into eBPF: map accesses become lookups + updates or per-CPU increments, helpers translate to register calls, and… | ||
| libperf: library for perf events monitoring | DevConf.CZ 2020 | 2020-01-24 |
Library libperf copies mature code from perf and currently exposes counting and sampling APIs that let user space create perf_event_attr events, open… | ||
| Processor tracing in perf | DevConf.CZ 2019 | 2019-01-25 |
Intel Processor Trace (Intel PT) records every branch in a highly compressed packet stream (TNT bits, PSB sync, timestamps), decodes with perf userspace via… | ||
| Performance lab. The power of the perf tool! | DevConf.CZ 2019 | 2019-01-25 |
Demonstrates using perf to find real issues: counts and samples CPUs, PMU power events, and SMIs (one generated by pressing the mute button), builds perf from… | ||
| Linux Perf Tools: Overview and Current Developments | Collaboration Summit 2013 | 2013-04-15 |
Perf now records PEBS-based memory loads with perf mem and shows cache-hierarchy breakdowns (example run: 10µs system-wide, 46% L1 hits), adds interval stat… | ||
