Please see https://www.linuxplumbersconf.org/event/2/page/7-attend For details. This year we expect to have close to a day set aside for RDMA related topics. Including up to half a day for the thorny general kernel issues related to get_user_pages(), particularly as exasperated by RDMA. We have been working on the following concepts for sessions, I've roughly marked names based on past participation in related email threads. As we get closer to the conference date we will be organizing leaders for each section based on these lists, please let us know of any changes, or desire to be a leader! RDMA and get_user_pages ======================= Dan Williams Matthew Wilcox John Hubbard Nicholas Piggin Jan Kara RDMA, DAX and persistant memory co-existence. Explore the limits of what is possible without using On Demand Paging Memory Registration. Discuss 'shootdown' of userspace MRs Dirtying pages obtained with get_user_pages() can oops ext4 discuss open solutions. RDMA and PCI peer to peer ========================= Don Dutile Alex Williamson Christoph Hellwig Stephen Bates Logan Gunthorpe JA(C)rA'me Glisse Christian KA?nig Bjorn Helgaas RDMA and PCI peer to peer transactions. IOMMU issues. Integration with HMM. How to expose PCI BAR memory to userspace and other drivers as a DMA target. Improving testing of RDMA with syzkaller, RXE and Python ======================================================== Noa Osherovich Don Dutile Jason Gunthorpe Problem solve RDMA's distinct lack of public tests. Provide a better framework for all drivers to test with, and a framework for basic testing in userspace. Worst remaining unfixed syzkaller bugs and how to try to fix them How to hook syzkaller more deeply into RDMA. IOCTL conversion and new kABI topics ==================================== Jason Gunthorpe Alex Rosenbaum Attempt to close on the remaining tasks to complete the project Restore fork() support to userspace Container and namespaces for RDMA topics ======================================== Parav Pandit Doug Ledford Remaining sticky situations with containers namespaces in sysfs and legacy all-namespace operation Remaining CM issues Security isolation problems Very large Contiguous regions in userspace ========================================== Christopher Lameter Parav Pandit Poor performance of get_user_pages on very large virtual ranges No standardized API to allocate regions to user space Carry over from last year As we get closer to the conference date the exact schedule will be published on the conference web site. I belive we have the Thursday set aside right now. If there are any last minute topics people would like to see please let us know. See you all in Vancouver! Thanks, Jason & Leon
