Allan from Klara Systems shares a series of stories from supporting users deploying FreeBSD in the field across various industries. These stories come from the silent users of FreeBSD, those that the community often do not know or hear about. Be that because they happen in the quieter corners of industry, where it is not common to discuss the technical challenges you face or how you overcame them, or just from people who are not well connected to the community, or choose not to make waves.
These stories provide insight into how FreeBSD gets used beyond the stories we already know, how it is used in industries that never mention what OS they use, or where you might never expect to find FreeBSD. Sharing these stories can help the community ensure these users continue to get the most out of FreeBSD.

![Hardware-accelerated program tracing on FreeBSD By Bojan Novković
Hardware tracing facilities are designed to capture various metrics and information about software execution with a minimal performance overhead, making them a valuable tool for performance analyses and debugging. FreeBSD recently gained a new in-kernel framework for hardware-accelerated tracing technologies (hwt(8) [1]) with support for ARM64 and Intel CPUs.
This talk will cover the work that went into adding support for Intels Processor Trace technology in hwt(8). Well start by covering several key concepts related to hardware-accelerated tracing and use them to explore the architecture of FreeBSDs hwt(8) framework. Well then move on to a case study of Intel Processor Trace technology, giving a brief overview of its features before diving into key implementation details. The talk will also include a short demo of hwt(8)s features on the Intel platform.
