Real-time Linux technology – Paul McKenney, Distinguished engineer, IBM
Paul focuses on the realtime Linux -rt patchset, which represents an impressive advance in technology, with a single code base supporting realtime response from embedded systems to realtime enterprise-level SMP systems. This talk gives a high-level overview of a few of the underlying technologies that make this possible, including high-resolution timers, priority inheritance, threaded interrupts, and synchronization primitives (this latter being where the bulk of Paul's contributions reside). These technologies are helping Linux to bring realtime response into mainstream and enterprise workloads. (39 slides)
Paul E. McKenney is a distinguished engineer at IBM and has worked on SMP, NUMA, and RCU algorithms for longer than he cares to admit (see this if you don't believe this). He has recently become quite interested in getting realtime response from mid-range SMP systems. Prior to that, he worked on packet-radio and Internet protocols (but long before the Internet became popular), system administration, business applications, and realtime systems, the latter on early 1980s eight-bit systems. He is extremely thankful that today's computers have much more than 64 kbytes of memory. His hobbies include running and the usual house-wife-and-kids habit.

Booting Linux on embedded PowerPC systems – Matt Tyrlik
There are two approaches for booting the operating system on a computer system. One requires the OS to have detailed knowledge of the underlying hardware, which requires the OS to contain code specific to each hardware platform implementation. The second approach relies on the firmware to provide the OS with an abstracted view of the hardware, which minimizes the amount of platform dependent code and reduces OS changes required to support new hardware platforms. The Linux community has chosen the second approach for all PowerPC 64-bit and 32-bit Linux board support implementations, based on the Open Firmware device tree concept. Topics covered will include the Open Firmware device tree concept as implemented on PowerPC systems, discussion related to passing the device tree information between the firmware and the OS, the flat device tree implementation and device tree compiler, and work currently carried out by the Power.org consortium to standardize the device tree structure for PowerPC embedded systems and to provide architecture specification for PowerPC embedded systems. (20 slides)
A senior software engineer with IBM, Matt Tyrlik has been working with embedded PowerPC systems for years. He has been involved in number of embedded projects ranging from set-top-box to hand-held devices. His work includes IBM PIBS firmware for embedded PowerPC processors and well as PowerPC 405/440/460 Instruction Set Simulator. Matt has great deal of experience with embedded and real time operating systems.

Kernel.org development and the embedded world – Andrew Morton, Lead maintainer, kernel.org
Andrew summarizes the kernel.org development and decision-making processes. Special focus is placed upon how they impact the developers of Linux for embedded products, including the economics of using a modern kernel versus staying on a frozen older kernel version, and the economics of maintaining private patchsets versus merging work back into the public kernel. For those who choose to work with the kernel.org team, Andrew looks at how that can most effectively be done. (15 slides)
The keeper of the mm tree patchset for the Linux kernel, and the kernel's lead maintainer, Andrew Morton works with Linux creator Linus Torvalds, kernel subsystem maintainers, Linux distribution companies, hardware vendors, and other parties to ensure that the public production kernel meets their needs. He is the final arbitrator on determining what code is accepted into the Linux production kernel, and is known for being a provocative public speaker. Andrew currently works at Google, and was formerly a fulltime OSDL fellow at the Open Source Development Labs. He was previously employed as principal engineer by Digeo Interactive, responsible for the base OS in Digeo's digital home entertainment products. Before Digeo, Andrew was a product development manager for Nortel Networks' R&D labs in Australia.

Appropriate community practices: social and technical lessons – Deepak Saxena, Software Engineer, Linux Kernel, One Laptop Per Child
With the increasing popularity of Linux in the embedded world, HW vendors are jumping on the bandwagon to add kernel support for their devices/chipsets/SOCs. We in the community keep seeing the same mistakes made (both technical and social) repetitively. We use examples of what not do when working within the Linux development ecosystem to illustrate appropriate practices to increase your probability of successful code adoption. (13 slides)
OLPC is a non profit organization that is supported by individuals, businesses and foundations with a mission of ensuring all school-aged children in the developing world are able to engage effectively with their own personal laptop, networked to the world, so that they, their families and their communities can openly learn and learn about learning. Until recently, Deepak was the lead kernel maintainer at MontaVista software, a position in which he focused on various areas including merging patches, providing direction on technology roadmaps, and developing processes. Previous to that role he was the lead maintainer of the Linux kernel port to the Intel IXP4xx and IXP2xxx network processors found on various WiFi, WiMax, and cellular routers. Deepak also worked at Intel Corporation and helped lead the development of the Intelligent I/O (I2O) stack for Linux. Deepak has been using Linux since 1993 and playing with the kernel for about 10 years. When not hacking, Deepak likes to go on bike rides, seek out good beer, and world travel.
