Hi Yuri, For functional regression test and performance comparison test, witch aspect we should test? For example, network i/o, network migration, network device hotplug/unplug or other tests? And how to judge VIRTIO_F_ANY_LAYOUT is used when runs with modern virtio-net-pci device? Thanks Yu Wang (In reply to Yu Wang from comment #1) > Hi Yuri, > > > For functional regression test and performance comparison test, witch aspect > we should test? > For example, network i/o, network migration, network device hotplug/unplug > or other tests?

I'll ack this it as soon as the BZ will be 'modified' Additionally this can be checked in driver's log at startup/enable. > > Thanks > Yu Wang Hi, Reproduce this bug with build 175, cannot find VIRTIO_F_ANY_LAYOUT initialize Test with build 176 , it shows VIRTIO_F_ANY_LAYOUT in traceview log: 00000192 netkvm.sys 4 7856 3 192 01\08\2020-23:28:41:296 ParaNdis_InitializeContext[ParaNdis_InitializeContext] Assuming VIRTIO_F_ANY_LAYOUT for V1 device 00000193 netkvm.sys 4 7856 3 193 01\08\2020-23:28:41:300 ParaNdis_InitializeContext status = 0x0 Test on win7-64,win8-32,win2012r2 and win10-64 virtio-win-prewhql-176 qemu-kvm-4.1.0-20.module+el8.1.1+5309+6d656f05.x86_64 kernel-4.18.0-147.3.1.el8_1.x86_64 So, this function has been used. Wenli will do the performance comparison test. Thanks Yu Wang Release in virtio-win 176 Virtio-win-prewhql-178 netkvm function and WHQL Tests all passed, And according to comment#4, performance tests passed. So this bug is verified.
