Reconfigurable Computing Architecture for the Linux Kernel
summary
Proposal defines a Linux-side architecture that dynamically loads FPGA functions as packaged AF descriptors compiled into device tree overlays, supports both discoverable (PCIe) and non-discoverable (AXI) interconnects, and manages placement, eviction and affinity across x86 and ARM systems. OpenCL kernels are treated as offload AFs, bitstreams support partial reconfiguration, vendor plugins handle proprietary synthesis steps, and exposure into guests uses vfio so accelerators can be assigned to VMs.
