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 kexecJason 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 oopsNVIDIA’s Manish Honap posts work that lets guests drive a virtual HDM decoder and device reset while the host keeps the physical mapping.
By kexecA C-based variant driver for nova-core draws a full Rust counter-proposal and VFIO maintainer pushback on long-term review capacity.
By kexecJason Gunthorpe used Claude to remix ConnectX DMA loopback support into kernel VFIO tests, cutting a month-plus job to days.
By oopsA redesigned MSI path lets 64-bit RISC-V translate interrupt targets like DMA, unlocking default IOMMU paging and userspace device assignment.
By kexecAndrew 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 oopsA 27-patch series from NVIDIA lets VMs program virtual HDM decoders and resets while the host keeps physical memory decode.
By kexecJason 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 kexecA 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.
