Paravirt I/O Drivers for Linux BoF

A new V4L2 core framework: an overview and future plans

Explain the current state of kgdb, kdb. Discuss the future architectural plans for combining kgdb, kdb and kernel mode settings and proposed advanced single stepping APIs.

Discusses pro and cons of a unified mechanism to report platform errors.

Per backing device dirty data writeback replaces pdflush driven writeback in an attempt to speed up this operation.

Fine grained locking to improve scalability of the Linux VFS

What can the Userspace RCU LGPL library do to help your application scale well on large multiprocessor systems ?

I present a new algorithm for scalable concurrent hash tables, performance results for this algorithm (2-10x more scalable than Linux), and potential applications.

The perfcounters infrastructures is fast moving into being the unifying channel for hw and software performance analisys

Last years libv4l2 presentation ended with a slide future with bullet points of features to be added, so where we stand today? And what will happen in the coming year?

oFono telephony stack

A walk through the pieces of a modern Linux desktop, which manage the hardware that is coming and going and failing.

A case study of the Portland Oregon Regional Transportation Archive Listing (PORTAL) database on PostgreSQL and Linux.

It is compelling to integrate complex embedded systems with Linux USB userspace code. However, the complexity of userspace interface adds significant risk to the development cycle. Integrating a USB2.0 Isochronous mode ARM embedded system with Linux host software presents an end to end design challenge requiring not just a view of Linux from the 'inside' but also from the 'outside'. Some of the challenges Linux added to an already complex embedded system development will be presented, with some ideas to reduce the barries to entry and learning curve for embedded systems and host communication.
