[Qemu-devel] e1000 emulation and mmio_exists counter

Hi list, I am testing e1000 emulation with qemu 2.5. Command line: -netdev tap,fd=21,id=hostnet0 \ -device e1000,netdev=hostnet0,id=net0,mac=$MAC1,bus=pci.0,addr=0x4 AFAIU, e1000 is emulated in qemu (userspace) and each i/o should cause vmexit to userspace. And each exit to userspace should incr

Hello, Is anyone interested in a patch for an unstable, though working e1000 emulation for QEMU? It is aimed for this chip-set version: 0e:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller I originally created it very recently to provide a virtual NIC that supp
