DTrace 2.0 for GentooOct 23, 2024The real, mythical DTrace comes to Gentoo! Need to dynamically trace your kernel or userspace programs, with rainbows, ponies, and unicorns - and all entirely safely and in production?! All required kernel options are already enabled in the newest stable Gentoo distribution kernel; if you are compiling manually, the DTrace ebuild will inform you about required configuration changes. Internally, DTrace 2.0 for Linux builds on the BPF engine of the Linux kernel, so don’t be surprised if the awesome cross-compilation features of Gentoo are used to install a gcc that outputs BPF code (which, btw, also comes in very handy for sys-apps/systemd ). You can start with our DTrace wiki page, the DTrace for Linux page on GitHub, or the original documentation for Illumos.
