https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277326 --- Comment #5 from Zhenlei Huang <zlei@FreeBSD.org> --- (In reply to Zhenlei Huang from comment #4) > I see lots of comparing of vm_guest in hyperv device drivers. I guess they should be removed to correctly probe Hyper-V devices, to correctly support Hyper-V enlightenment feature. In case KVM should be reported when Hyper-V enlightenmen is enabled. # grep -r 'VM_GUEST_HV' sys/dev/hyperv sys/dev/hyperv/storvsc/hv_storvsc_drv_freebsd.c: if (vm_guest == VM_GUEST_HV) { sys/dev/hyperv/vmbus/vmbus.c: if (device_get_unit(parent) != 0 || vm_guest != VM_GUEST_HV || sys/dev/hyperv/vmbus/vmbus.c: if (device_get_unit(dev) != 0 || vm_guest != VM_GUEST_HV || sys/dev/hyperv/vmbus/vmbus.c: if (vm_guest != VM_GUEST_HV || sc == NULL) sys/dev/hyperv/vmbus/hyperv.c: if (vm_guest == VM_GUEST_HV) sys/dev/hyperv/vmbus/hyperv.c: if (vm_guest != VM_GUEST_HV) sys/dev/hyperv/vmbus/vmbus_res.c: if (device_get_unit(dev) != 0 || vm_guest != VM_GUEST_HV || sys/dev/hyperv/vmbus/x86/hyperv_x86.c: if (vm_guest != VM_GUEST_HV) sys/dev/hyperv/vmbus/aarch64/hyperv_aarch64.c: vm_guest = VM_GUEST_HV; sys/dev/hyperv/hvsock/hv_sock.c: if (vm_guest != VM_GUEST_HV) sys/dev/hyperv/netvsc/if_hn.c: if (vm_guest != VM_GUEST_HV) -- You are receiving this mail because: You are the assignee for the bug.help
