This article is just a collection of ideas and posts.
Recently I was doing some performance-tunning of QEMU/KVM with kinds of pure-software ways. However, it ended with the existence of QEMU/KVM's process load.
I just remembered that I used to do some co-sim work with National Instruments LabView about ten years ago...(during college life...fk...I'm still young...)
TBD: Start QEMU instance(s) with passthrough-ed PCI(PCI-SRIOV) devices like ethernet controller or NVMe controller designed in PCI FPGA to offload the emulated works.
TBD: Start QEMU instance with devices ported to passthrough-ed PCI FPGA as many as possible, i.e. usb controller, ethernet controller and etc..(Like a dock with kinds of devices...)
But I think it will be replaced by Trial No.1.
SoC FPGA, as DOM0.
ASIC offload with slight host management.
