Steven ROSTEDT

STEVEN ROSTEDT

Steven Rostedt is one of the original developers of the PREEMPT_RT patch; he started working in 2004 with the goal of turning Linux into a Real Time designed operating system. Although, the PREEMPT_RT patch still exists out of tree, several of its features have made it into the vanilla kernel. One of these features being Ftrace, the official tracer of Linux. Steven is the main author, developer and maintainer of Ftrace. He has also created ktest.pl, which is a testing framework within the Linux kernel, and is the one responsible for the kernel build option “make localmodconfig”. Outside of development, Steven has done numerous presentations around the world. He’s also been on the Kernel Summit program committee from 2010-2016, and is currently one the Linux Foundation’s Technical Advisory Board (TAB) members, which represents the kernel community to the foundation.

Steven joined VMware at the start of 2017 as one of the core developers at the heart of VMware’s Open Source Technology Center, focused on providing value and leadership in spreading open source expertise and culture across the company. Through VMware, Steven continues to work with various open source communities contributing his time to develop and enhance open source software.

Ezequiel Garcia has been an active contributor of several Linux Kernel subsystems, including Video4Linux and MTD. Mostly focusing on embedded devices since 2012, he is currently working for Collabora on Linux Kernel upstream projects. Ezequiel regularly speaks about the Linux Kernel at various latin-american events, and also spoke at ELC in 2013 to present the results of a Linux Foundation CE Workgroup project on kernel memory usage analysis.

Alexander Graf

Alexander Graf

Alexander is a QEMU, KVM, openSUSE and U-Boot developer who likes to work across various CPU architectures.

He started to work for SUSE about 11 years ago and since then has progressed through various subsystems. He initially wrote the SVM emulation bits in QEMU, added nested virtualization support to KVM on AMD CPUs, wrote and maintained a good chunk of the KVM support for PowerPC for a few years, maintained the QEMU PowerPC parts for about as long, initiated and still participates on ARM support in openSUSE and recently dove into U-Boot land where he now maintains the UEFI execution support.

Rafael maintains the Linux kernel’s power management infrastructure and the core ACPI support code. He works at Intel Open Source Technology Center and focuses on the mainline Linux kernel development. He has been actively contributing to Linux since 2005, in particular to the kernel’s suspend/hibernate  subsystem, power management in general (IO runtime PM framework, CPUFreq, CPUIdle, PM QoS, system wakeup framework etc.), hot-plug infrastructure, core ACPI support, core PCI support and more. Before joining Intel he worked at the Faculty of Physics of the University of Warsaw as a lecturer and IT specialist,
he was a Linux and IT consultant and he ran a business of his own. Rafael holds a PhD in Physics from the University of Warsaw.
