Linux Plumbers Conf 2011

Meetup for ARM Linux distributions interested in working together

Unifying Linux kernel backport efforts (slides)

A characteristic study on ad hoc synchronization in software systems and a tool called SyncFinder to automatically identify and annotate them. (slides)

A look at the problems related to latency in server workloads and solutions we are exploring to improve average and tail latencies.

Codemap is a semantic source code visualizer helping to navigate, visualize and search a large codebase using ideas similar to google maps. (slides)

Discussion on how to automatically diagnose firmware issue that can affect Linux. (slides)

Ensemble is a new opensource configuration management and tool for deploying services into a cloud and data center environments

In this presentation, we discuss the set of design and implementation details that play into developing a Linux-based, open-source, large scale, infrastructure level distributed system that implements a private cloud computing platform.

Finding and burying Configuration Defects in Linux with the undertaker (slides)

Building an efficient and maintenable API for allowing userspace to program GPU is one of the most important piece of the graphic stacks (slides)

Adapting and extending the kernel dmaengine API for high-end dma controllers like EDMA found on Texas Instruments DaVinci devices and SDMA found on OMAP devices.

An introduction to the Smatch static checker and a look at the future. (slides)

Presentation of the new LTTng 2.0 kernel and userspace tracer.

Folproof filesystem freeze API for user space daemons and guest agents. (slides)

An overview and update on the Patchwork patch-tracking system. (slides)

Remus is a HA system for Xen VMs that preserves complete Guest OS runtime state (including network connections) upon failover.

You already use version control for your software, but what about your build dependencies and your system infrastructures? Come hear about Apters, our solution for reproducible builds and infrastructures. (slides)

Scalability problems in/caused by fork (slides)

How can we reintroduce the zero-copy behaviour that was removed as part of the process of upstreaming Xen's netback driver (slides)

Session lead for Virtualization micro conf

Scaling Linux, both up and down

How should thermal management for ARM devices be done within existing thermal constructs (hwmon and thermal framework)

Improving reliability of Linux device drivers against hardware failures and hardware specification bugs (slides)

Can the "trace" utility merge perf and ftrace. (slides)

Tracing

Tracing the Guest from the Host, a discussion (slides)

Presentation of the Userspace RCU library features. (slides)

VFIO allows exporting PCI devices to userspace drivers. Discussion of using this interface for assigning physical devices to virtual machines and obstacles remaining for integration. (slides)

How does Virtio compare with traditional Xen PV drivers? (slides)

An overview of what is involved in making video calls and the issues typically encountered on mobile platforms. (slides)

Yabusame is yet another live migration mechanism for Qemu/KVM, which implements the migration technique known as "postcopy" or "lazy" migration. (slides)

A look at the fairness and wake-up latency improvements that can be achieved by extending vruntime beyond the per-cpu level. (slides)

Most modern network and storage controllers have multiple interrupts but Linux kernel has inconsistent management (slides)

Learn to read the output from lockdep when your code can trigger a deadlock (slides)

How to use QEMU to develop future hardware models to develop and test device drivers before hardware is available. (slides)

A work-in-progress new ABI for x86 combines the memory footprint of a 32-bit process with the enhanced capabilities of the x86-64 ISA. (slides)
