Team

Linux user since 1995. Joined Red Hat in 2000 and started working on PREEMPT_RT in 2005, still working on the real-time kernel today.

Daniel Wagner is a seasoned software engineer with expertise in  real-time Linux, networking, and storage. His career includes contributions at BMW, working on the GENIVI project and autonomous driving with PREEMPT_RT, followed by Siemens, where he developed embedded systems leveraging RT capabilities. Currently at SUSE, he enhances the RT version of the distribution, enabling new customer use cases. He maintains stable RT tools for the Stable RT group.

Joseph is a Linux Kernel Engineer on the UEK kernel team at Oracle. Over the past 30 years, he has worked for many large companies as well as several startups in the computing industry. Joseph enjoys working in the areas of kernel scheduling, performance, real-time and fixing bugs in any area of the kernel. He currently maintains the upstream v5.15.y real-time patch set.

Luis installed his first Linux box in 1996. Joined Red Hat around 2007, as a member of the Real Time team, and has been working with PREEMPT_RT ever since.

In 2001, Steven worked at TimeSys porting their Real Time version of the Linux kernel to various architectures. In 2003, he started working with Siemens to create a version of Linux that can deterministically interact with their real-time power plant software. During this time, in 2004, Steven came across the work from Ingo Molnar and Thomas Gleixner that was also creating a real-time version of the Linux kernel called the preempt-realtime patch. Steven started building his work on top of this work and in the process was able to find bugs and even create improvements to that real-time project. One of which was to break up the global priority inheritance lock and instead use a PI lock for the task and a wait lock for the mutex. Steven joined Red Hat in
2006 and helped them to create a real-time Linux offering. As more projects started using the now called PREEMPT_RT patch, in a meeting at the Real-Time Workshop it was decided that the PREEMPT_RT patch required stable releases that followed the upstream kernel stable releases that had a real-time version attached to it. Steven led the effort to create a process that would help maintain stable releases for various real-time versions, and even though Steven is mostly working on non-real-time projects today, he still helps lead the effort of the real-time stable kernels

Tom has been doing Linux kernel work for over 20 years, mainly in the area of kernel tracing, but has also done significant work in the Linux perf and IAA crypto subsystems. His first Linux kernel commit was the introduction of the relayfs filesystem in 2005, which was an offshoot of a collaboration between the Linux Trace Toolkit (LTT) and the K42 operating system teams. He was also a member of the embedded Linux kernel team for the Yocto Project, and led that project’s initial Board Support Package (BSP) team, as well as its kernel tinification efforts, designed to arrive at the smallest-possible-footprint Linux kernels for embedded systems.
