--- Comment #13 from Tommy P <tommy...@gmail.com> --- (In reply to John Hartley from comment #12) Hi John, If you look again at the pciconf output: none1@pci0:1:0:0 Implies that no driver were loaded for that pci device at slot 0:1:0:0 since FreeBSD's VirtIO drivers currently does not support PCI-E bus. The rest of the pciconf are for debugging driver. For the other output such as: sym0@pci0:2:0:0 Implies that FreeBSD's LSI/Symbios SCSI (sym) were loaded successfully. Thus, any HDD attached to that controller would work. Unfortunately, I don't think this SCSI controller supports UEFI boot. Here are the details of pciconf, from my understanding, of how FreeBSD's VirtIO drivers work: none1@pci0:1:0:0: class=0x020000 card=0x11001af4 chip=0x10411af4 rev=0x01 hdr=0x00 *) rev=0x01 implies PCI-E bus while rev=0x00 implies PCI bus *) last 4 digits of card/chip implies the vendor ID: 0x1af4 (per /usr/src/sys/dev/virtio/pci/virtio_pci.h) *) if device is on PCI bus, the first 4 digits of 'card' imply device type (per /usr/src/sys/dev/virtio/virtio_ids.h) *) if device is on PCI-E bus, the first 4 digits of 'chip' - 0x1040 should match device type from /usr/src/sys/dev/virtio/virtio_ids.h. Thus, 0x1041 - 0x1040 = 0x1 which is VirtIO NIC per pciconf's verbose output: #define VIRTIO_ID_NETWORK 1 And 0x1048 - 0x1040 = 0x8 which is VirtIO SCSI: #define VIRTIO_ID_SCSI 8 The current VirtIO drivers does not have the necessary codes to detect the device ID connected to the PCI-E bus nor have the correct memory address to attach the driver for that same bus. As for non VirtIO not working, my fresh install of 12.0 using OVMF works OK for both sym SCSI and em NIC. I don't have 11.2 OVMF to test upgrade. But all of my non OVMF VMs work OK too except where Q35 + VirtIO are concerned as per my bug report. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
