Gentoo Linux has now implemented support for DTrace 2.0. The DTrace 2.0 instrumentation is used for dynamic tracing of the kernel and applications in user space, as well as for monitoring system behavior and diagnosing issues in real-time with minimal impact on performance. A notable feature of the DTrace 2.0 branch is its ability to work with the eBPF subsystem and kernel tracing mechanisms without requiring the loading of a special kernel module.
To use DTrace in Gentoo, simply install the `dev-debug/dtrace` package, and all necessary configuration is already included in the default kernel provided by the distribution. When building a custom kernel, the ebuild will now output a hint about the options that should be included for DTrace to work.
