Microconferences at Linux Plumbers Conference: Rust

Linux Plumbers Conference 2022 is pleased to host the Rust MC

Rust is a systems programming language that is making great strides in becoming the next big one in the domain.

Rust for Linux aims to bring it into the kernel since it has a key property that makes it very interesting to consider as the second language in the kernel: it guarantees no undefined behavior takes place (as long as unsafe code is sound). This includes no use-after-free mistakes, no double frees, no data races, etc.

This microconference intends to cover talks and discussions on both Rust for Linux as well as other non-kernel Rust topics.

Possible Rust for Linux topics:

  • Bringing Rust into the kernel (e.g. status update, next steps…).
  • Use cases for Rust around the kernel (e.g. drivers, subsystems…).
  • Integration with kernel systems and infrastructure (e.g. wrapping existing subsystems safely, build system, documentation, testing, maintenance…).

Possible Rust topics:

  • Language and standard library (e.g. upcoming features, memory model…).
  • Compilers and codegen (e.g. rustc improvements, LLVM and Rust, rustc_codegen_gcc, gccrs…).
  • Other tooling and new ideas (Cargo, Miri, Clippy, Compiler Explorer, Coccinelle for Rust…).
  • Educational material.
  • Any other Rust topic within the Linux ecosystem.

Please come and join us in the discussion about Rust in the Linux ecosystem.

We hope to see you there!

Microconferences at Linux Plumbers Conference: Power Management and Thermal Control

Linux Plumbers Conference 2022 is pleased to host the Power Management and Thermal Control Microconference

The Power Management and Thermal Control microconference focuses on frameworks related to power management and thermal control, CPU and device power-management mechanisms, and thermal-control methods. In particular, we are interested in extending the energy-efficient scheduling concept beyond the energy-aware scheduling (EAS), improving the thermal control framework in the kernel to cover more use cases and making system-wide suspend (and power management in general) more robust.

The goal is to facilitate cross-framework and cross-platform discussions that can help improve energy-awareness and thermal control in Linux.

Suggested topics:

  • Energy-efficient scheduling beyond EAS
  • Per-CPU idle injection from user space for thermal control
  • A generic energy model description
  • Extending the DTPM framework by adding more supported devices to it
  • Thermal control core code improvements
  • Combining DTPM with the thermal control framework
  • Generic DVFS support for SCMI-based platforms
  • Improving the genpd governor for CPUs
  • More integration between PM-runtime and system-wide PM

Please come and join us in the discussion about keeping your systems cool.

We hope to see you there!

Microconferences at Linux Plumbers Conference: System Boot and Security

Linux Plumbers Conference 2022 is pleased to host the System Boot and Security Microconference

In the fourth year in a row, System Boot and Security microconference is are going to bring together people interested in the firmware, bootloaders, system boot, security, etc., and discuss all these topics. This year we would particularly like to focus on better communication and closer cooperation between different Free Software and Open Source projects. In the past we have seen that the lack of cooperation’s between projects very often delays introduction of very interesting and important features with TrenchBoot being very prominent example.

The System Boot and Security MC is very important to improve such communication and cooperation, but it is not limited to this kind of problems. We would like to encourage all stakeholders to bring and discuss issues that they encounter in the broad sense of system boot and security.

Expected topics:

  • TPMs, HSMs, secure elements
  • Roots of Trust: SRTM and DRTM
  • Intel TXT, SGX, TDX
  • Growing Attestation ecosystem,
  • IMA
  • TrenchBoot, tboot
  • UEFI, coreboot, U-Boot, LinuxBoot, hostboot
  • Measured Boot, Verified Boot, UEFI Secure Boot, UEFI Secure Boot Advanced Targeting (SBAT)
  • shim
  • boot loaders: GRUB2, SeaBIOS, network boot, PXE, iPXE,
  • u-root
  • OpenBMC, u-bmc
  • legal, organizational and other similar issues relevant for people interested in system boot and security.

Please come and join us in the discussion about how to keep your system secure from the very boot.

We hope to see you there!

Microconferences at Linux Plumbers Conference: VFIO/IOMMU/PCI

Linux Plumbers Conference 2022 is pleased to host the VFIO/IOMMU/PCI Microconference

The PCI interconnect specification, the devices that implement it, and the system IOMMUs that provide memory and access control to them are nowadays a de-facto standard for connecting high-speed components, incorporating more and more features such as:

  • Address Translation Service (ATS)/Page Request Interface (PRI)
  • Single-root I/O Virtualization (SR-IOV)/Process Address Space ID (PASID)
  • Shared Virtual Addressing (SVA)
  • Remote Direct Memory Access (RDMA)
  • Peer-to-Peer DMA (P2PDMA)
  • Cache Coherent Interconnect for Accelerators (CCIX)
  • Compute Express Link (CXL)
  • Data Object Exchange (DOE)
  • Component Measurement and Authentication (CMA)
  • Integrity and Data Encryption (IDE)
  • Security Protocol and Data Model (SPDM)
  • Gen-Z

These features are aimed at high-performance systems, server and desktop computing, embedded and SoC platforms, virtualization, and ubiquitous IoT devices.

The kernel code that enables these new system features focuses on coordination between 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 and userspace APIs to be designed in-sync and in a clean way for all three sub-systems.

The VFIO/IOMMU/PCI micro-conference focuses on the kernel code that enables these new system features that often require coordination between the VFIO, IOMMU and PCI sub-systems.

Tentative topics 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
    • /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.)

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 !
