The xAPIC mode is the default setting so this option is redundant. It will be deprecated in a future version. .It Fl A Generate ACPI tables. Required for .Fx Ns /amd64 guests. .It Fl b Enable a low-level console device supported by .Fx kernels compiled with .Cd "device bvmconsole" . This option will be deprecated in a future version. .It Fl c Op Ar setting ... Number of guest virtual CPUs and/or the CPU topology. The default value for each of .Ar numcpus , .Ar sockets , .Ar cores , and .Ar threads is 1. The current maximum number of guest virtual CPUs is 16. If .Ar numcpus is not specified then it will be calculated from the other arguments. The topology must be consistent in that the .Ar numcpus must equal the product of .Ar sockets , .Ar cores , and .Ar threads . If a .Ar setting is specified more than once the last one has precedence. .It Fl C Include guest memory in core file. .It Fl D Destroy the VM on guest initiated power-off. .It Fl e Force .Nm to exit when a guest issues an access to an I/O port that is not emulated. This is intended for debug purposes. .It Fl g Ar gdbport For .Fx kernels compiled with .Cd "device bvmdebug" , allow a remote kernel kgdb to be relayed to the guest kernel gdb stub via a local IPv4 address and this port. This option will be deprecated in a future version. .It Fl G Ar port Start a debug server that uses the GDB protocol to export guest state to a debugger. An IPv4 TCP socket will be bound to the supplied .Ar port to listen for debugger connections. Only a single debugger may be attached to the debug server at a time. If .Ar port begins with .Sq w , .Nm will pause execution at the first instruction waiting for a debugger to attach. .It Fl h Print help message and exit. .It Fl H Yield the virtual CPU thread when a HLT instruction is detected. If this option is not specified, virtual CPUs will use 100% of a host CPU. .It Fl l Op Ar help|lpcdev Ns Op , Ns Ar conf Allow devices behind the LPC PCI-ISA bridge to be configured. The only supported devices are the TTY-class devices .Ar com1 and -.Ar com2 -and the boot ROM device -.Ar bootrom . +.Ar com2 , +the boot ROM device +.Ar bootrom , +and the debug/test device +.Ar pc-testdev . .Pp .Ar help print a list of supported LPC devices. .It Fl m Ar memsize Ns Op Ar K|k|M|m|G|g|T|t Guest physical memory size in bytes. This must be the same size that was given to .Xr bhyveload 8 . .Pp The size argument may be suffixed with one of K, M, G or T (either upper or lower case) to indicate a multiple of kilobytes, megabytes, gigabytes, or terabytes. If no suffix is given, the value is assumed to be in megabytes. .Pp .Ar memsize defaults to 256M. .It Fl p Ar vcpu:hostcpu Pin guest's virtual CPU .Em vcpu to .Em hostcpu . .It Fl P Force the guest virtual CPU to exit when a PAUSE instruction is detected. .It Fl r Ar file Resume a guest from a snapshot. The guest memory contents are restored from .Ar file , and the guest device and vCPU state are restored from the file .Dq Ar file Ns .kern . .Pp Note that the current snapshot file format requires that the configuration of devices in the new VM match the VM from which the snapshot was taken by specifying the same .Op Fl s and .Op Fl l options. The count of vCPUs and memory configuration are read from the snapshot. .It Fl s Op Ar help|slot,emulation Ns Op , Ns Ar conf Configure a virtual PCI slot and function. .Pp .Nm provides PCI bus emulation and virtual devices that can be attached to slots on the bus. There are 32 available slots, with the option of providing up to 8 functions per slot. .Bl -tag -width 10n .It Ar help print a list of supported PCI devices. .It Ar slot .Ar pcislot[:function] .Ar bus:pcislot:function .Pp The .Ar pcislot value is 0 to 31. The optional .Ar function value is 0 to 7. The optional .Ar bus value is 0 to 255. If not specified, the .Ar function value defaults to 0. If not specified, the .Ar bus value defaults to 0. .It Ar emulation .Bl -tag -width 10n .It Li hostbridge | Li amd_hostbridge .Pp Provide a simple host bridge. This is usually configured at slot 0, and is required by most guest operating systems. The .Li amd_hostbridge emulation is identical but uses a PCI vendor ID of .Li AMD . .It Li passthru PCI pass-through device. .It Li virtio-net Virtio network interface. .It Li virtio-blk Virtio block storage interface. .It Li virtio-scsi Virtio SCSI interface. .It Li virtio-9p Virtio 9p (VirtFS) interface. .It Li virtio-rnd Virtio RNG interface. .It Li virtio-console Virtio console interface, which exposes multiple ports to the guest in the form of simple char devices for simple IO between the guest and host userspaces. .It Li ahci AHCI controller attached to arbitrary devices. .It Li ahci-cd AHCI controller attached to an ATAPI CD/DVD. .It Li ahci-hd AHCI controller attached to a SATA hard-drive. .It Li e1000 Intel e82545 network interface. .It Li uart PCI 16550 serial device. .It Li lpc -LPC PCI-ISA bridge with COM1 and COM2 16550 serial ports and a boot ROM. +LPC PCI-ISA bridge with COM1 and COM2 16550 serial ports, a boot ROM, and, +optionally, the debug/test device. The LPC bridge emulation can only be configured on bus 0. .It Li fbuf Raw framebuffer device attached to VNC server. .It Li xhci eXtensible Host Controller Interface (xHCI) USB controller. .It Li nvme NVM Express (NVMe) controller. .It Li hda High Definition Audio Controller. .El .It Op Ar conf This optional parameter describes the backend for device emulations.

The optional parameters .Ar socket and .Ar hook may be used to set the .Xr ng_socket 4 node name and source hook. The .Ar ADDRESS , .Ar HOOK and .Ar NAME must comply with .Xr netgraph 4 addressing rules. .El .Pp Block storage devices: .Bl -tag -width 10n .It Pa /filename Ns Oo , Ns Ar block-device-options Oc .It Pa /dev/xxx Ns Oo , Ns Ar block-device-options Oc .El .Pp The .Ar block-device-options are: .Bl -tag -width 8n .It Li nocache Open the file with .Dv O_DIRECT . .It Li direct Open the file using .Dv O_SYNC . .It Li ro Force the file to be opened read-only. .It Li sectorsize= Ns Ar logical Ns Oo / Ns Ar physical Oc Specify the logical and physical sector sizes of the emulated disk.

A maximum of 16 ports per device can be created. Every port is named and corresponds to a Unix domain socket created by .Nm . .Nm accepts at most one connection per port at a time. .Pp Limitations: .Bl -bullet -offset 2n .It Due to lack of destructors in .Nm , sockets on the filesystem must be cleaned up manually after .Nm exits. .It There is no way to use the "console port" feature, nor the console port resize at present. .It Emergency write is advertised, but no-op at present. .El .El .Pp Framebuffer devices: .Bl -tag -width 10n .It Xo .Oo rfb= Ns Oo Ar IP\&: Oc Ns Ar port Oc Ns Oo ,w= Ns Ar width Oc Ns Oo ,h= Ns .Ar height Oc Ns Oo ,vga= Ns Ar vgaconf Oc Ns Oo Ns ,wait Oc Ns Oo ,password= Ns .Ar password Oc .Xc .Bl -tag -width 8n .It Ar IPv4:port No or Ar [IPv6%zone]:port An .Ar IP address and a .Ar port VNC should listen on. The default is to listen on localhost IPv4 address and default VNC port 5900. An IPv6 address must be enclosed in square brackets and may contain an optional zone identifier. .It Ar width No and Ar height A display resolution, width and height, respectively. If not specified, a default resolution of 1024x768 pixels will be used. Minimal supported resolution is 640x480 pixels, and maximum is 1920x1200 pixels. .It Ar vgaconf Possible values for this option are .Dq io (default), .Dq on , and .Dq off . PCI graphics cards have a dual personality in that they are standard PCI devices with BAR addressing, but may also implicitly decode legacy VGA I/O space .Pq Ad 0x3c0-3df and memory space .Pq 64KB at Ad 0xA0000 . The default .Dq io option should be used for guests that attempt to issue BIOS calls which result in I/O port queries, and fail to boot if I/O decode is disabled. .Pp The .Dq on option should be used along with the CSM BIOS capability in UEFI to boot traditional BIOS guests that require the legacy VGA I/O and memory regions to be available. .Pp The .Dq off option should be used for the UEFI guests that assume that VGA adapter is present if they detect the I/O ports. An example of such a guest is .Ox in UEFI mode. .Pp Please refer to the .Nm .Fx wiki page .Pq Lk https://wiki.freebsd.org/bhyve for configuration notes of particular guests. .It wait Instruct .Nm to only boot upon the initiation of a VNC connection, simplifying the installation of operating systems that require immediate keyboard input. This can be removed for post-installation use. .It password This type of authentication is known to be cryptographically weak and is not intended for use on untrusted networks. Many implementations will want to use stronger security, such as running the session over an encrypted channel provided by IPsec or SSH. .El .El .Pp xHCI USB devices: .Bl -tag -width 10n .It Li tablet A USB tablet device which provides precise cursor synchronization when using VNC. .El .Pp NVMe devices: .Bl -tag -width 10n .It Li devpath Accepted device paths are: .Ar /dev/blockdev or .Ar /path/to/image or .Ar ram=size_in_MiB . .It Li maxq Max number of queues. .It Li qsz Max elements in each queue. .It Li ioslots Max number of concurrent I/O requests. .It Li sectsz Sector size (defaults to blockif sector size). .It Li ser Serial number with maximum 20 characters. .El .Pp AHCI devices: .Bl -tag -width 10n .It Li nmrr Nominal Media Rotation Rate, known as RPM. value 1 will indicate device as Solid State Disk. default value is 0, not report. .It Li ser Serial Number with maximum 20 characters. .It Li rev Revision Number with maximum 8 characters. .It Li model Model Number with maximum 40 characters. .El .Pp HD Audio devices: .Bl -tag -width 10n .It Li play Playback device, typically .Ar /dev/dsp0 . .It Li rec Recording device, typically .Ar /dev/dsp0 . .El .El .It Fl S Wire guest memory. .It Fl u RTC keeps UTC time. .It Fl U Ar uuid Set the universally unique identifier .Pq UUID in the guest's System Management BIOS System Information structure. By default a UUID is generated from the host's hostname and .Ar vmname . .It Fl w Ignore accesses to unimplemented Model Specific Registers (MSRs). This is intended for debug purposes. .It Fl W Force virtio PCI device emulations to use MSI interrupts instead of MSI-X interrupts. .It Fl x The guest's local APIC is configured in x2APIC mode. .It Fl Y Disable MPtable generation. .It Ar vmname Alphanumeric name of the guest. This should be the same as that created by .Xr bhyveload 8 . .El .Sh DEBUG SERVER The current debug server provides limited support for debuggers. .Ss Registers Each virtual CPU is exposed to the debugger as a thread. .Pp General purpose registers can be queried for each virtual CPU, but other registers such as floating-point and system registers cannot be queried. .Ss Memory Memory (including memory mapped I/O regions) can be read and written by the debugger. Memory operations use virtual addresses that are resolved to physical addresses via the current virtual CPU's active address translation. .Ss Control The running guest can be interrupted by the debugger at any time .Pq for example, by pressing Ctrl-C in the debugger . .Pp Single stepping is only supported on Intel CPUs supporting the MTRAP VM exit. .Pp Breakpoints are supported on Intel CPUs that support single stepping. Note that continuing from a breakpoint while interrupts are enabled in the guest may not work as expected due to timer interrupts firing while single stepping over the breakpoint. .Sh SIGNAL HANDLING .Nm deals with the following signals: .Pp .Bl -tag -width indent -compact .It SIGTERM Trigger ACPI poweroff for a VM .El .Sh EXIT STATUS Exit status indicates how the VM was terminated: .Pp .Bl -tag -width indent -compact .It 0 rebooted .It 1 powered off .It 2 halted .It 3 triple fault .It 4 exited due to an error .El .Sh EXAMPLES If not using a boot ROM, the guest operating system must have been loaded with .Xr bhyveload 8 or a similar boot loader before .Xr bhyve 4 can be run. Otherwise, the boot loader is not needed. .Pp To run a virtual machine with 1GB of memory, two virtual CPUs, a virtio block device backed by the .Pa /my/image filesystem image, and a serial port for the console: .Bd -literal -offset indent bhyve -c 2 -s 0,hostbridge -s 1,lpc -s 2,virtio-blk,/my/image \\ -l com1,stdio -A -H -P -m 1G vm1 .Ed .Pp Run a 24GB single-CPU virtual machine with three network ports, one of which has a MAC address specified: .Bd -literal -offset indent bhyve -s 0,hostbridge -s 1,lpc -s 2:0,virtio-net,tap0 \\ -s 2:1,virtio-net,tap1 \\ -s 2:2,virtio-net,tap2,mac=00:be:fa:76:45:00 \\ -s 3,virtio-blk,/my/image -l com1,stdio \\ -A -H -P -m 24G bigvm .Ed .Pp Run an 8GB quad-CPU virtual machine with 8 AHCI SATA disks, an AHCI ATAPI CD-ROM, a single virtio network port, an AMD hostbridge, and the console port connected to an .Xr nmdm 4 null-modem device. .Bd -literal -offset indent bhyve -c 4 \\ -s 0,amd_hostbridge -s 1,lpc \\ -s 1:0,ahci,hd:/images/disk.1,hd:/images/disk.2,\\ hd:/images/disk.3,hd:/images/disk.4,\\ hd:/images/disk.5,hd:/images/disk.6,\\ hd:/images/disk.7,hd:/images/disk.8,\\ cd:/images/install.iso \\ -s 3,virtio-net,tap0 \\ -l com1,/dev/nmdm0A \\ -A -H -P -m 8G .Ed .Pp Run a UEFI virtual machine with a display resolution of 800 by 600 pixels that can be accessed via VNC at: 0.0.0.0:5900. .Bd -literal -offset indent bhyve -c 2 -m 4G -w -H \\ -s 0,hostbridge \\ -s 3,ahci-cd,/path/to/uefi-OS-install.iso \\ -s 4,ahci-hd,disk.img \\ -s 5,virtio-net,tap0 \\ -s 29,fbuf,tcp=0.0.0.0:5900,w=800,h=600,wait \\ -s 30,xhci,tablet \\ -s 31,lpc -l com1,stdio \\ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \\ uefivm .Ed .Pp Run a UEFI virtual machine with a VNC display that is bound to all IPv6 addresses on port 5900. .Bd -literal -offset indent bhyve -c 2 -m 4G -w -H \\ -s 0,hostbridge \\ -s 4,ahci-hd,disk.img \\ -s 5,virtio-net,tap0 \\ -s 29,fbuf,tcp=[::]:5900,w=800,h=600 \\ -s 30,xhci,tablet \\ -s 31,lpc -l com1,stdio \\ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \\ uefivm .Ed .Sh SEE ALSO .Xr bhyve 4 , .Xr netgraph 4 , .Xr ng_socket 4 , .Xr nmdm 4 , .Xr vmm 4 , .Xr ethers 5 , .Xr bhyvectl 8 , .Xr bhyveload 8 .Pp .Rs .%A Intel .%B 64 and IA-32 Architectures Software Developer’s Manual .%V Volume 3 .Re .Sh HISTORY .Nm first appeared in .Fx 10.0 . .Sh AUTHORS .An Neel Natu Aq Mt neel@freebsd.org .An Peter Grehan Aq Mt grehan@freebsd.org Index: head/usr.sbin/bhyve/pci_lpc.c =================================================================== --- head/usr.sbin/bhyve/pci_lpc.c (revision 367761) +++ head/usr.sbin/bhyve/pci_lpc.c (revision 367762) @@ -1,487 +1,510 @@ /*- * SPDX-License-Identifier: BSD-2-Clause-FreeBSD * * Copyright (c) 2013 Neel Natu * Copyright (c) 2013 Tycho Nightingale * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
