Standards development and application at the Operating System (OS) level are in a complex and evolving state. This talk will not only explore what it means to be POSIX compliant, but will focus on the question: What is the status of POSIX compliance within the BSD sphere in 2024? What are the drivers for POSIX compliance today?
This talk will explore what POSIX compliance means and whether BSD is officially POSIX compliant. Feedback from the community will be appreciated, and a discussion of the community's concepts of the value of POSIX will be sought.

![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. Hardware-accelerated program tracing on FreeBSD By Bojan Novković](https://i.ytimg.com/vi/NrBGw8N4qL4/mqdefault.jpg)
