If you are wondering how the dimensional eBPF data collection works under the hood, check out my earlier post about xcapture: eBPF performance analysis and the 0x.tools repo Summary xtop is like the Linux top tool, but extended with x-ray vision and ability to view your performance data from any chosen angle (that eBPF allows to access). This enables dimensional performance analysis on Linux and t

XCapture v3: Linux Performance Analysis with Modern eBPF and DuckDB2025 · tanelpoder.com · ▲6Hello, I just released the (eventually) final version of my xcapture eBPF performance tool that now uses modern eBPF (libbpf, BTF, CO-RE, passive sampling using task iterators, task-local storage, etc). The previous BCC-based v2 version got a good discussion here last year [1], but due to BCC being less flexible and now deprecated, I decided to pull the plug and start from scratch with the latest eBPF features available. I'm targeting Linux kernels 5.14 and up. So Ubuntu 20 with HWE kernel (5.15) already works, RHEL9 works, Oracle's RHEL8 clone OEL8 with Oracle's UEK7 kernel (5.15) also…

xstack – Passive eBPF Linux stack profiling without tracepoints2025 · tanelpoder.com · ▲6Here's the latest eBPF performance tool of mine - xstack. It's a minimal tool, just 165 lines of eBPF C and under 500 lines of userland C code (including all comments and boilerplate!). It uses the libbpf and (Rust) BlazeSym libraries though (which are a lot of code). The point (and difference) of this tool is that it can sample both the kernel and userspace stack traces of all threads in your system. Traditionally, the "bpf_get_stack()" helper can not read userspace stack traces of other tasks in Linux, but since Linux 5.18 we can combine sleepable eBPF task iterator programs with a new…

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…
