DMA-buf gains mapping types beyond scatterlist
A revised series lets exporters pick how buffers are described at pin or map time, aiming at VFIO, vGPU, and private links.

Rust VFIO PCI abstractions land with NVIDIA vGPU driver
A twelve-patch series wires nova-core SR-IOV into VFIO so NVIDIA virtual functions can be assigned to userspace.
By renderPCI core gains Live Update support for kexec device continuity
David Matlack’s v10 series lets selected PCI endpoints keep DMA running across a host kernel upgrade without topology or routing changes.
By oopsRISC-V gains IOMMU MSI remapping, unlocking DMA and VFIO by default
Andrew Jones's v6 series maps IMSIC MSI targets like DMA, letting 64-bit RISC-V turn on IOMMU_DMA, iommufd, and device assignment.
By oopsClaude-written mlx5 driver proposed for Linux VFIO selftests
Jason Gunthorpe says an AI produced a ConnectX selftest driver in days that once took months of human work.
By oopsWhen dual maintenance ends: Rust Binder deletion and the nova-core binding fight
A proposal to delete the C Binder driver and NVIDIA’s expanding Rust vGPU stack force the kernel community past experiments into the harder question of retiring C subsystems.
By kexecClaude builds mlx5 VFIO selftest driver in four days
Jason Gunthorpe submitted a ConnectX selftest series largely generated by Anthropic's model, cutting a job that usually takes months down to about a week.
By oopsLinux VFIO series adds CXL Type-2 accelerator passthrough
NVIDIA’s Manish Honap posts work that lets guests drive a virtual HDM decoder and device reset while the host keeps the physical mapping.
By kexecNVIDIA vGPU VFIO driver sparks Rust rewrite debate
A C-based variant driver for nova-core draws a full Rust counter-proposal and VFIO maintainer pushback on long-term review capacity.
By kexecAI-written mlx5 driver lands in VFIO selftests in a week
Jason Gunthorpe used Claude to remix ConnectX DMA loopback support into kernel VFIO tests, cutting a month-plus job to days.
By oopsRISC-V IOMMU gains MSI remapping, default DMA-IOMMU, and VFIO
A redesigned MSI path lets 64-bit RISC-V translate interrupt targets like DMA, unlocking default IOMMU paging and userspace device assignment.
By kexecRISC-V IOMMU series unlocks MSI remap, DMA, and VFIO assign
Andrew Jones posts v4 work to translate device MSIs through the IOMMU, opening default IOMMU_DMA and userspace PCIe assignment on 64-bit RISC-V.
By oopsVFIO patches add CXL Type-2 accelerator passthrough for guests
A 27-patch series from NVIDIA lets VMs program virtual HDM decoders and resets while the host keeps physical memory decode.
By kexecmlx5 VFIO selftest lands after four days of Claude-assisted coding
Jason Gunthorpe submitted a 10-patch series that brings ConnectX DMA and MSI coverage to the kernel VFIO tests, cut from the usual multi-month effort.
By kexecRISC-V IOMMU gains MSI remapping, unlocking DMA and VFIO
A 19-patch series from Qualcomm lets RISC-V translate device MSIs like DMA traffic and opens the door to PCIe device assignment in KVM guests.
