Hello everyone! We are pleased to announce that there will be another VFIO/IOMMU/PCI Microconference at this year's Linux Plumbers Conference (LPC), from 12th to the 14th of September in Dublin, Ireland. LPC is a hybrid event this year; attendance can be in person or remote. In this microconference we want to discuss ongoing developments around the VFIO, IOMMU and PCI subsystems and their interactions in Linux. Tentative topics that are under consideration for this year include (but not limited to): * PCI: - Cache Coherent Interconnect for Accelerators (CCIX)/Compute Express Link (CXL) expansion memory and accelerators management - Data Object Exchange (DOE) - Integrity and Data Encryption (IDE) - Component Measurement and Authentication (CMA) - Security Protocol and Data Model (SPDM) - I/O Address Space ID Allocator (IOASID) - INTX/MSI IRQ domain consolidation - Gen-Z interconnect fabric - ARM64 architecture and hardware - PCI native host controllers/endpoints drivers current challenges and improvements (e.g., state of PCI quirks, etc.) - PCI error handling and management e.g., Advanced Error Reporting (AER), Downstream Port Containment (DPC), ACPI Platform Error Interface (APEI) and Error Disconnect Recover (EDR) - Power management and devices supporting Active-state Power Management (ASPM) - Peer-to-Peer DMA (P2PDMA) - Resources claiming/assignment consolidation - Probing of native PCIe controllers and general reset implementation - Prefetchable vs non-prefetchable BAR address mappings - Untrusted/external devices management - DMA ownership models - Thunderbolt, DMA, RDMA and USB4 security * VFIO: - Write-combine on non-x86 architectures - I/O Page Fault (IOPF) for passthrough devices - 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: - /dev/iommufd development - IOMMU virtualization - IOMMU drivers SVA interface - DMA-API layer interactions and the move towards generic dma-ops for IOMMU drivers - Possible IOMMU core changes (e.g., better integration with device-driver core, etc.) Please submit your proposals on the LPC website at: https://lpc.events/event/16/abstracts/ Make sure to select the "VFIO/IOMMU/PCI MC" in the Track pulldown menu. Looking forward to seeing you all there, either in Dublin or virtual! :) The organizers, Alex Williamson Bjorn Helgaas Jörg Rödel Lorenzo Pieralisi Krzysztof Wilczyński
