We are very pleased to announce that our final schedule is public!
Please take a look at all the great technical content at this year virtual LPC.
You can view the schedule by main blocks , or by track, or as a complete detailed view.
At this time we are closing the CfPs for all tracks. We have still room for a limited number of Birds of a Feather sessions. If you want to propose one, even during the conference, and the necessary participants are all registered, please send an email to our lpc-contact@lists.linuxplumbersconf.org mailing list.
A heartfelt Thank You to all our Speakers and Microconference Leaders, you all have done an incredible job in making this year’s conference successful, in spite of all the challenges that a remote and distributed conference entails.
See you virtually next week!
Hello there, thank you all for the very strong interest in LPC 2020!
We have sold out the last ticket today. We have a lot of attendees and speakers this year for our virtual conference! Almost 1000 registrations!
Do not despair though, because there will be the opportunity to watch the conference live streaming on YouTube. We are still sorting out our channels, but keep an eye on our blog and social media in the next couple of days, where we’ll announce how to watch live.
Thanks, and see you next week!
We have received several requests for T-shirts this year.
We have always produced T-shirts for attendees since the early days of LPC, and we don’t want to miss the opportunity to offer them this year too.
Since we are all remote, we have set up a LPC Gift Shop where you can order T-shirts in your favorite colors and sizes. We also have made the designs available if you want to print your own.
Enjoy!
We hit our registration cap again and have added a few more passes. The final date for purchasing passes is August 19th at 11:59pm PST. If the passes sell out before then we will not be adding more. Thank you all once again for your enthusiasm and we look forward to seeing you August 24-28!
After a careful review we have decided to release more passes. We are thrilled with the interest for this first ever online Linux Plumbers. The highlight of Linux Plumbers is the microconferences which are heavily focused on discussion and problem solving. To give the best experience for discussion, we have chosen to use an open source virtual platform that offers video for all participants. The platform recommends not having more than a certain number of people in each room at a time, hence putting a cap on registration to avoid hitting that limit. We do have solutions that will hopefully allow as many people as possible to experience Plumbers. We appreciate your patience and enthusiasm.
Linux Plumbers is currently sold out of regular registration tickets. Although the conference is virtual this year our virtual platform cannot support an unlimited number of attendees, hence the cap on registration. We are currently reviewing our capacity limits to see if we can allow more people to attend without over burdening the virtual platform and potentially preventing discussion. We will make another announcement next week regarding registration.
We are pleased to announce that the Toolchain Microconference has been accepted into the 2020 Linux Plumbers Conference!
The GNU toolchain has direct impact on the development of the Linux kernel and it is imperative that the developers of both ecosystems have an understanding of each other’s needs. Linux Plumbers is the perfect venue for the two communities to interact, and the GNU Toolchain microconference’s purpose is to facilitate that happening.
Last year’s meetup at Linux Plumbers proved that it is critical that the two communities communicate with each other. As a result of last year’s microconference, the GNU toolchain has completed adding support for BPF, in a more flexible and usable way and system call wrappers in glibc were improved. There have been security features derived from the discussions, such as zeroing of registers when entering a function and implicit initialization of atomics.
This year’s topics to be discussed include:
- How to improve the continual communication between GNU toolchain developers and kernel developers.
- Creating a standardization on how to compile the kernel that is suitable for all Live kernel patching frameworks.
- Now that BPF support is in the GNU toolchain, including a new BPF instruction simulator, we’d like some feedback from kernel developers regarding its usability and whether more features are needed.
- Compact C Type Format (CTF) has been added to the GNU toolchain, and there is work underway to also add BTF support. However some useful features are still missing (like backtraces) and their design needs to be discussed and agreed upon among toolchain and kernel developers.
Come and join us in the discussion about innovating the most efficient and functional toolchain for building the Linux kernel.
We hope to see you there!
We are pleased to announce that the Application Ecosystem Microconference has been accepted into the 2020 Linux Plumbers Conference!
The Linux kernel is the foundation of the Linux systems, but it is not much use without applications that run on top of it. The application experience relies on the kernel for performance, stability and responsiveness. Plumbers is the perfect venue to have the kernel and app ecosystems under one roof to discuss and learn together and make a better application experience on the Linux platform.
This year’s topics to be discussed include:
- Schedulers as related to applications
- Systemd / cgroups resource management
- Display technologies (X11, Wayland, others)
- Graphics drivers
- Innovative technology applicable to userspace
- Memory management (tools, tweaks, guidance for apps)
- Power saving (tools, tweaks, guidance for apps)
- Security
- Linux on Mobile
- Containerized Apps
Come and join the discussion on making this the year of the Linux Desktop!
We hope to see you there!
We are pleased to announce that the Power Management and Thermal Control Microconference has been accepted into the 2020 Linux Plumbers Conference!
Power management and thermal control is an important area in the Linux ecosystem to help with the global environment. Optimizing the amount of work that is achieved while having long battery life and keeping the box from overheating is critical in today’s world. This meeting will focus on continuing to have Linux be an efficient operating system while still lowering the cost of running a data center.
Last year’s meetup at Linux Plumbers resulted in the introduction of thermal pressure support into the CPU scheduler as well as several improvements to the thermal framework, such as a netlink implementation of thermal notification and improvements to CPU cooling. Discussions from last year also helped to improve systems-wide suspend testing tools.
This year’s topics to be discussed include:
Come and join us in the discussion about extending the battery life of your laptop and keeping it cool.
We hope to see you there!
We are pleased to announce that the VFIO/IOMMU/PCI Microconference has been accepted into the 2020 Linux Plumbers Conference!
The PCI interconnect specification, the devices implementing it, and the system IOMMUs providing memory/access control to them are incorporating more and more features aimed at high performance systems (eg PCI ATS (Address Translation Service)/PRI(Page Request Interface), enabling Shared Virtual Addressing (SVA) between devices and CPUs), that require the kernel to coordinate the PCI devices, the IOMMUs they are connected to and the VFIO layer used to manage them (for userspace access and device passthrough) with related kernel interfaces that have to be designed in-sync for all three subsystems.
The kernel code that enables these new system features requires coordination between VFIO/IOMMU/PCI subsystems, so that kernel interfaces and userspace APIs can be designed in a clean way.
The following was a result of last years successful Linux Plumbers microconference:
- Software defined Non-Transparent Bridges (NTB) can now be implemented using the PCIe endpoint subsystem NTB using PCIe endpoints can now be represented using configfs rather than using device tree.
- User interfaces for per-group default IOMMU domain type patches have been merged.
- IO Address Space Identifier (IOASID) allocator has been merged and later support was added for custom allocator for guest use.
Last year’s Plumbers resulted in a write-up justifying the dual-stageSMMUv3 integration but more work is needed to persuade the relevant maintainers.
Topics for this year include (but not limited to):
VFIO
- Shared Virtual Addressing (SVA) interface
- Single-root I/O Virtualization(SRIOV)/ Process Address Space ID (PASID) integration
- PASID in SRIOV virtual functions
- Device assignment/sub-assignment
IOMMU
- IOMMUs virtualization: Partially discussed at LPC19 but further discussion needed for virtio-iommu firmware bindings (ie ACPI) and vSMMUv3 development
- IOMMU drivers SVA interface consolidation:
- Possible IOMMU core changes (like splitting up iommu_ops, better integration with device-driver core)
- DMA-API layer interactions and how to get towards generic dma-ops for IOMMU drivers
- Sharing Extended Page Tables with VT-d 2nd level
Come and join us in the discussion in helping Linux keep up with the new features being added to the PCI interconnect specification.
We hope to see you there!
