Thursday night reception for LPC

Thanks to the generous sponsorship of Intel, the Linux Plumbers Conference is pleased to announce that there will be an additional social event this year. On Thursday August 20th, we will be gathering at the Seattle Rock Bottom Brewery—just a short walk from the conference venue and hotel—for drinks and dinner in a relaxed setting. The evening’s event will be showcasing local beers, wines, and spirits, but some of the more standard items (like single-malt scotches and cocktails) will also be available.

Since there will be various BoFs and extended microconferences going later in the evening on Thursday, the event has been structured to accommodate that. The event will not have a buffet and will, instead, provide food made to order. It will run until midnight and dinner orders can be placed up until 23:30, so folks can show up any time and still get the food of their choice, hot and fresh. That said, if we all order right at the 18:00 start, the waiting time may get long. So, if you aren’t working late, a walk around Seattle (perhaps after popping in for a drink) would work well to put some space around the food orders. The Rock Bottom is a large venue with lots of tables for discussions and the like, so continuing a conversation there, rather than at the venue, will work out well.

We look forward to seeing everyone at the Rock Bottom on Thursday!

Microconference schedule now available

The Linux Plumbers Conference starts in less than three weeks and so the schedule for Microconferences is now available!  Looking forward to seeing you all there!

General Registration is now Closed

We’re pleased to announce that thanks to overwhelming support, interest in Linux Plumbers Conference has exceeded expectations.  The downside is that the conference is now officially full. Originally we were going to post a warning today, but a sudden surge of corporate registrations caught us off guard, so we had to close immediately.

If you still haven’t registered but would like to participate, contact us. We are running a waiting list on a first come first serve basis but with priority given to people who have accepted microconference topics. You could also try to use one of the sponsors tickets if your employer can provide one to you.

We look forward to seeing you in Seattle for a memorable conference.

Graphics Microconference Accepted into 2015 Linux Plumbers Conference

Although the Year of the Linux Desktop has yet to arrive, a surprising number of Linux users nevertheless need graphics support. This is because there have been a number of years of the Linux smartphone, the Linux television, the Linux digital sign/display/billboard, the Linux automobile, and more. This microconference will cover a number of topics including atomic modesetting in KMS, buffer allocation, verified-secure graphics pipelines, fencing and synchronisation, Wayland, and more.

For more information on this important topic, see the wiki page.

Thermal Microconference Accepted into 2015 Linux Plumbers Conference

In stark contrast with decades past, thermal issues in computer systems now means much more than fans and heat sinks, and this microconference looks at some of the things that are now handled in software. The topics include the thermal framework, handling of temperature sensors, and different approaches to handling overtemperature conditions, ranging up to and including closed-loop control. Of course, software that is not tested can be assumed not to work, and the best way to ensure that testing happens when needed is to automate it, so automated testing of thermal subsystems is also on the agenda. Coordination with userspace is useful in order to determine how best to shed computational load, as is coordination among multiple cooling devices.

File and Storage Systems Microconference Accepted into 2015 Linux Plumbers Conference

Despite having been in production use for many decades, file and storage systems are very active areas, and have retained the ability to provide many new-technology surprises. This year’s edition of the File and Storage Systems Microconference will look at improved error reporting, filesystem-level encryption in traditional filesystems, SMR drives, online fsck, persistent memory, smart block-layer support in traditional filesystems, better interoperability of and support for NFS and Samba, userspace filesystem innovations, and much else besides.

Boot, Init, and Config Microconference Accepted into 2015 Linux Plumbers Conference

The combination of security issues, kernel tinification, and a renewed concern about fast boot has intensified focus on system boot, initialization, and configuration, so much so that there is now a Linux Plumbers Conference Microconference focused on these topics.

In addition to secure boot and minimizing size and bloat, this microconference will delve into a number of topics related to boot speed. These topics include tuning systemd for embedded systems, optimizing and/or delaying memory initialization, deferring initcall-based initialization, introducing parallelism and multicore earlier in boot, speeding up early-boot I/O, pre-loading known configurations, speeding up installation, and of course improved timing and tracing analysis earlier in system startup. In short, the fast-boot work has definitely moved into the sub-second realm. A final bonus topic is better configuring for cloud- and container-based workloads.

Persistent Memory Microconference Accepted into 2015 Linux Plumbers Conference

The topic of persistent memory is back to the future for those of us old enough to have used core memory, but today’s persistent memory boasts densities, speeds, latencies, and capacities that are well beyond the scope even of science fiction back in the core-memory era.

However, with extreme densities, speeds, latencies, and capacities come interesting technical challenges. This microconference will therefore cover the “struct page” problem, performance hotspots in both kernel and userspace I/O fastpaths, managing access mechanisms such as DAX, providing atomic sector updates, and more.

For more information on this topic, see the wiki page.

We hope to see you there!

Performance and Scalability Microconference Accepted into 2015 Linux Plumbers Conference

Core counts keep rising, and that means that the Linux kernel continues to encounter interesting performance and scalability issues. Which is not a bad thing, since it has been well over ten years since the “free lunch” of exponential CPU-clock frequency increases came to an abrupt end. This microconference will therefore look at futex scaling, address-space scaling, improvements to queued spinlocks, additional lockless algorithms, userspace per-CPU critical sections, and much else besides.

For more information on this topic, please see the wiki page.

Networking Microconference Accepted into 2015 Linux Plumbers Conference

In the past, this has been called the Network Virtualization Microconference, but this year’s instance is branching out to include IPv6 and Security.

Network-virtualization topics include networking for multi-tenant container clusters, reducing network-namespace load on the system, intelligent processing at the edge of the data center, programmable datapath (as in fun with eBPF, OVS, nft, and much else besides), hardware support, and protocol development.

IPv6 topics include performance (can it catch up to IPv4?), consolidation of common IPv4/IPv6 functionality, solving the IPv6 datacenter addressing problem, and providing network virtualization without encapsulation using logical IPv6 overlays.

Security topics include scalable networking security policies for containers, securing applications in multi-host data centers, encryption of overlays, and hardware support.

It appears that coordinated work in all three of these areas is required to make good progess. For more information, see the wiki page.
