131 | b3f046c2 | Kevin Wolf | @table @option |
132 | 5824d651 | blueswir1 | @item file=@var{file} |
133 | 5824d651 | blueswir1 | This option defines which disk image (@pxref{disk_images}) to use with |
134 | 5824d651 | blueswir1 | this drive. If the filename contains comma, you must double it |
135 | 5824d651 | blueswir1 | (for instance, "file=my,,file" to use file "my,file"). |
136 | 5824d651 | blueswir1 | @item if=@var{interface} |
137 | 5824d651 | blueswir1 | This option defines on which type on interface the drive is connected. |
138 | 5824d651 | blueswir1 | Available types are: ide, scsi, sd, mtd, floppy, pflash, virtio. |
139 | 5824d651 | blueswir1 | @item bus=@var{bus},unit=@var{unit} |
140 | 5824d651 | blueswir1 | These options define where is connected the drive by defining the bus number and |
141 | 5824d651 | blueswir1 | the unit id. |
142 | 5824d651 | blueswir1 | @item index=@var{index} |
143 | 5824d651 | blueswir1 | This option defines where is connected the drive by using an index in the list |
144 | 5824d651 | blueswir1 | of available connectors of a given interface type. |
145 | 5824d651 | blueswir1 | @item media=@var{media} |
146 | 5824d651 | blueswir1 | This option defines the type of the media: disk or cdrom. |
147 | 5824d651 | blueswir1 | @item cyls=@var{c},heads=@var{h},secs=@var{s}[,trans=@var{t}] |
148 | 5824d651 | blueswir1 | These options have the same definition as they have in @option{-hdachs}. |
149 | 5824d651 | blueswir1 | @item snapshot=@var{snapshot} |
150 | 5824d651 | blueswir1 | @var{snapshot} is "on" or "off" and allows to enable snapshot for given drive (see @option{-snapshot}). |
151 | 5824d651 | blueswir1 | @item cache=@var{cache} |
152 | 016f5cf6 | Alexander Graf | @var{cache} is "none", "writeback", "unsafe", or "writethrough" and controls how the host cache is used to access block data. |
153 | 5c6c3a6c | Christoph Hellwig | @item aio=@var{aio} |
154 | 5c6c3a6c | Christoph Hellwig | @var{aio} is "threads", or "native" and selects between pthread based disk I/O and native Linux AIO. |
155 | 5824d651 | blueswir1 | @item format=@var{format} |
156 | 5824d651 | blueswir1 | Specify which disk @var{format} will be used rather than detecting |
157 | 5824d651 | blueswir1 | the format. Can be used to specifiy format=raw to avoid interpreting |
158 | 5824d651 | blueswir1 | an untrusted format header. |
159 | 5824d651 | blueswir1 | @item serial=@var{serial} |
160 | 5824d651 | blueswir1 | This option specifies the serial number to assign to the device. |
161 | c2cc47a4 | Markus Armbruster | @item addr=@var{addr} |
162 | c2cc47a4 | Markus Armbruster | Specify the controller's PCI address (if=virtio only). |
163 | 5824d651 | blueswir1 | @end table |
164 | 5824d651 | blueswir1 | |
165 | 5824d651 | blueswir1 | By default, writethrough caching is used for all block device. This means that |
166 | 5824d651 | blueswir1 | the host page cache will be used to read and write data but write notification |
167 | 5824d651 | blueswir1 | will be sent to the guest only when the data has been reported as written by |
168 | 5824d651 | blueswir1 | the storage subsystem. |
169 | 5824d651 | blueswir1 | |
170 | 5824d651 | blueswir1 | Writeback caching will report data writes as completed as soon as the data is |
171 | 5824d651 | blueswir1 | present in the host page cache. This is safe as long as you trust your host. |
172 | 5824d651 | blueswir1 | If your host crashes or loses power, then the guest may experience data |
173 | c3177288 | Alexander Graf | corruption. |
174 | 5824d651 | blueswir1 | |
175 | c304d317 | Aurelien Jarno | The host page cache can be avoided entirely with @option{cache=none}. This will |
176 | 5824d651 | blueswir1 | attempt to do disk IO directly to the guests memory. QEMU may still perform |
177 | 5824d651 | blueswir1 | an internal copy of the data. |
178 | 5824d651 | blueswir1 | |
179 | 5824d651 | blueswir1 | Some block drivers perform badly with @option{cache=writethrough}, most notably, |
180 | 5824d651 | blueswir1 | qcow2. If performance is more important than correctness, |
181 | 0aa217e4 | Kevin Wolf | @option{cache=writeback} should be used with qcow2. |
182 | 5824d651 | blueswir1 | |
183 | 016f5cf6 | Alexander Graf | In case you don't care about data integrity over host failures, use |
184 | 016f5cf6 | Alexander Graf | cache=unsafe. This option tells qemu that it never needs to write any data |
185 | 016f5cf6 | Alexander Graf | to the disk but can instead keeps things in cache. If anything goes wrong, |
186 | 016f5cf6 | Alexander Graf | like your host losing power, the disk storage getting disconnected accidently, |
187 | c3177288 | Alexander Graf | etc. you're image will most probably be rendered unusable. When using |
188 | c3177288 | Alexander Graf | the @option{-snapshot} option, unsafe caching is always used. |
189 | 016f5cf6 | Alexander Graf | |
190 | 5824d651 | blueswir1 | Instead of @option{-cdrom} you can use: |
191 | 5824d651 | blueswir1 | @example |
192 | 5824d651 | blueswir1 | qemu -drive file=file,index=2,media=cdrom |

194 | 5824d651 | blueswir1 | |
195 | 5824d651 | blueswir1 | Instead of @option{-hda}, @option{-hdb}, @option{-hdc}, @option{-hdd}, you can |
196 | 5824d651 | blueswir1 | use: |

203 | 5824d651 | blueswir1 | |
204 | 5824d651 | blueswir1 | You can connect a CDROM to the slave of ide0: |

208 | 5824d651 | blueswir1 | |
209 | 5824d651 | blueswir1 | If you don't specify the "file=" argument, you define an empty drive: |
210 | 5824d651 | blueswir1 | @example |
211 | 5824d651 | blueswir1 | qemu -drive if=ide,index=1,media=cdrom |
212 | 5824d651 | blueswir1 | @end example |
213 | 5824d651 | blueswir1 | |
214 | 5824d651 | blueswir1 | You can connect a SCSI disk with unit ID 6 on the bus #0: |
215 | 5824d651 | blueswir1 | @example |
216 | 5824d651 | blueswir1 | qemu -drive file=file,if=scsi,bus=0,unit=6 |

218 | 5824d651 | blueswir1 | |
219 | 5824d651 | blueswir1 | Instead of @option{-fda}, @option{-fdb}, you can use: |
220 | 5824d651 | blueswir1 | @example |
221 | 5824d651 | blueswir1 | qemu -drive file=file,index=0,if=floppy |
222 | 5824d651 | blueswir1 | qemu -drive file=file,index=1,if=floppy |

797 | 5824d651 | blueswir1 | trusted, this is a sufficient authentication mechanism. You may still wish |
798 | 5824d651 | blueswir1 | to set a password on the VNC server as a second authentication layer. The |

805 | 5824d651 | blueswir1 | Require that the client use SASL to authenticate with the VNC server. |
806 | 5824d651 | blueswir1 | The exact choice of authentication method used is controlled from the |
807 | 5824d651 | blueswir1 | system / user's SASL configuration file for the 'qemu' service. This |
808 | 5824d651 | blueswir1 | is typically found in /etc/sasl2/qemu.conf. If running QEMU as an |
809 | 5824d651 | blueswir1 | unprivileged user, an environment variable SASL_CONF_PATH can be used |
810 | 5824d651 | blueswir1 | to make it search alternate locations for the service config. |
811 | 5824d651 | blueswir1 | While some SASL auth methods can also provide data encryption (eg GSSAPI), |
812 | 5824d651 | blueswir1 | it is recommended that SASL always be combined with the 'tls' and |
813 | 5824d651 | blueswir1 | 'x509' settings to enable use of SSL and server certificates. This |
814 | 5824d651 | blueswir1 | ensures a data encryption preventing compromise of authentication |
815 | 5824d651 | blueswir1 | credentials. See the @ref{vnc_security} section for details on using |
816 | 5824d651 | blueswir1 | SASL authentication. |

820 | 5824d651 | blueswir1 | Turn on access control lists for checking of the x509 client certificate |
821 | 5824d651 | blueswir1 | and SASL party. For x509 certs, the ACL check is made against the |
822 | 5824d651 | blueswir1 | certificate's distinguished name. This is something that looks like |
823 | 5824d651 | blueswir1 | @code{C=GB,O=ACME,L=Boston,CN=bob}. For SASL party, the ACL check is |
824 | 5824d651 | blueswir1 | made against the username, which depending on the SASL plugin, may |
825 | 5824d651 | blueswir1 | include a realm component, eg @code{bob} or @code{bob@@EXAMPLE.COM}. |
826 | 5824d651 | blueswir1 | When the @option{acl} flag is set, the initial access list will be |
827 | 5824d651 | blueswir1 | empty, with a @code{deny} policy. Thus no one will be allowed to |
828 | 5824d651 | blueswir1 | use the VNC server until the ACLs have been loaded. This can be |
829 | 5824d651 | blueswir1 | achieved using the @code{acl} monitor command. |

1037 | c92ef6a2 | Jan Kiszka | Set IP network address the guest will see. Optionally specify the netmask, |
1038 | c92ef6a2 | Jan Kiszka | either in the form a.b.c.d or as number of valid top-most bits. Default is |
1039 | c92ef6a2 | Jan Kiszka | 10.0.2.0/8. |
1040 | c92ef6a2 | Jan Kiszka | |
1041 | c92ef6a2 | Jan Kiszka | @item host=@var{addr} |
1042 | c92ef6a2 | Jan Kiszka | Specify the guest-visible address of the host. Default is the 2nd IP in the |
1043 | c92ef6a2 | Jan Kiszka | guest network, i.e. x.x.x.2. |
1044 | ad196a9d | Jan Kiszka | |
1045 | ad196a9d | Jan Kiszka | @item restrict=y|yes|n|no |
1046 | ad196a9d | Jan Kiszka | If this options is enabled, the guest will be isolated, i.e. it will not be |
1047 | ad196a9d | Jan Kiszka | able to contact the host and no guest IP packets will be routed over the host |
1048 | ad196a9d | Jan Kiszka | to the outside. This option does not affect explicitly set forwarding rule. |
1049 | ad196a9d | Jan Kiszka | |
1050 | ad196a9d | Jan Kiszka | @item hostname=@var{name} |
1051 | ad196a9d | Jan Kiszka | Specifies the client hostname reported by the builtin DHCP server. |
1052 | ad196a9d | Jan Kiszka | |
1053 | c92ef6a2 | Jan Kiszka | @item dhcpstart=@var{addr} |
1054 | c92ef6a2 | Jan Kiszka | Specify the first of the 16 IPs the built-in DHCP server can assign. Default |
1055 | c92ef6a2 | Jan Kiszka | is the 16th to 31st IP in the guest network, i.e. x.x.x.16 to x.x.x.31. |
1056 | c92ef6a2 | Jan Kiszka | |
1057 | c92ef6a2 | Jan Kiszka | @item dns=@var{addr} |
1058 | c92ef6a2 | Jan Kiszka | Specify the guest-visible address of the virtual nameserver. The address must |
1059 | c92ef6a2 | Jan Kiszka | be different from the host address. Default is the 3rd IP in the guest network, |
1060 | c92ef6a2 | Jan Kiszka | i.e. x.x.x.3. |
1061 | c92ef6a2 | Jan Kiszka | |
1062 | ad196a9d | Jan Kiszka | @item tftp=@var{dir} |
1063 | ad196a9d | Jan Kiszka | When using the user mode network stack, activate a built-in TFTP |
1064 | ad196a9d | Jan Kiszka | server. The files in @var{dir} will be exposed as the root of a TFTP server. |
1065 | ad196a9d | Jan Kiszka | The TFTP client on the guest must be configured in binary mode (use the command |
1066 | c92ef6a2 | Jan Kiszka | @code{bin} of the Unix TFTP client). |
1067 | ad196a9d | Jan Kiszka | |
1068 | ad196a9d | Jan Kiszka | @item bootfile=@var{file} |
1069 | ad196a9d | Jan Kiszka | When using the user mode network stack, broadcast @var{file} as the BOOTP |
1070 | ad196a9d | Jan Kiszka | filename. In conjunction with @option{tftp}, this can be used to network boot |
1071 | ad196a9d | Jan Kiszka | a guest from a local directory. |
1072 | ad196a9d | Jan Kiszka | |
1073 | ad196a9d | Jan Kiszka | Example (using pxelinux): |
1074 | ad196a9d | Jan Kiszka | @example |
1075 | ad196a9d | Jan Kiszka | qemu -hda linux.img -boot n -net user,tftp=/path/to/tftp/files,bootfile=/pxelinux.0 |
1076 | ad196a9d | Jan Kiszka | @end example |
1077 | ad196a9d | Jan Kiszka | |
1078 | c92ef6a2 | Jan Kiszka | @item smb=@var{dir}[,smbserver=@var{addr}] |
1079 | ad196a9d | Jan Kiszka | When using the user mode network stack, activate a built-in SMB |
1080 | ad196a9d | Jan Kiszka | server so that Windows OSes can access to the host files in @file{@var{dir}} |
1081 | c92ef6a2 | Jan Kiszka | transparently. The IP address of the SMB server can be set to @var{addr}. By |
1082 | c92ef6a2 | Jan Kiszka | default the 4th IP in the guest network is used, i.e. x.x.x.4. |
1083 | ad196a9d | Jan Kiszka | |
1084 | ad196a9d | Jan Kiszka | In the guest Windows OS, the line: |
1085 | ad196a9d | Jan Kiszka | @example |
1086 | ad196a9d | Jan Kiszka | 10.0.2.4 smbserver |
1087 | ad196a9d | Jan Kiszka | @end example |
1088 | ad196a9d | Jan Kiszka | must be added in the file @file{C:\WINDOWS\LMHOSTS} (for windows 9x/Me) |
1089 | ad196a9d | Jan Kiszka | or @file{C:\WINNT\SYSTEM32\DRIVERS\ETC\LMHOSTS} (Windows NT/2000). |
1090 | ad196a9d | Jan Kiszka | |
1091 | ad196a9d | Jan Kiszka | Then @file{@var{dir}} can be accessed in @file{\\smbserver\qemu}. |
1092 | ad196a9d | Jan Kiszka | |
1093 | ad196a9d | Jan Kiszka | Note that a SAMBA server must be installed on the host OS in |
1094 | ad196a9d | Jan Kiszka | @file{/usr/sbin/smbd}. QEMU was tested successfully with smbd versions from |
1095 | ad196a9d | Jan Kiszka | Red Hat 9, Fedora Core 3 and OpenSUSE 11.x. |
1096 | ad196a9d | Jan Kiszka | |
1097 | 3c6a0580 | Jan Kiszka | @item hostfwd=[tcp|udp]:[@var{hostaddr}]:@var{hostport}-[@var{guestaddr}]:@var{guestport} |
1098 | c92ef6a2 | Jan Kiszka | Redirect incoming TCP or UDP connections to the host port @var{hostport} to |
1099 | c92ef6a2 | Jan Kiszka | the guest IP address @var{guestaddr} on guest port @var{guestport}. If |
1100 | c92ef6a2 | Jan Kiszka | @var{guestaddr} is not specified, its value is x.x.x.15 (default first address |
1101 | 3c6a0580 | Jan Kiszka | given by the built-in DHCP server). By specifying @var{hostaddr}, the rule can |
1102 | 3c6a0580 | Jan Kiszka | be bound to a specific host interface. If no connection type is set, TCP is |
1103 | c92ef6a2 | Jan Kiszka | used. This option can be given multiple times. |
1104 | ad196a9d | Jan Kiszka | |
1105 | ad196a9d | Jan Kiszka | For example, to redirect host X11 connection from screen 1 to guest |
1106 | ad196a9d | Jan Kiszka | screen 0, use the following: |
1107 | ad196a9d | Jan Kiszka | |
1108 | ad196a9d | Jan Kiszka | @example |
1109 | ad196a9d | Jan Kiszka | # on the host |
1110 | 3c6a0580 | Jan Kiszka | qemu -net user,hostfwd=tcp:127.0.0.1:6001-:6000 [...] |
1111 | ad196a9d | Jan Kiszka | # this host xterm should open in the guest X11 server |
1112 | ad196a9d | Jan Kiszka | xterm -display :1 |
1113 | ad196a9d | Jan Kiszka | @end example |
1114 | ad196a9d | Jan Kiszka | |
1115 | ad196a9d | Jan Kiszka | To redirect telnet connections from host port 5555 to telnet port on |
1116 | ad196a9d | Jan Kiszka | the guest, use the following: |
1117 | ad196a9d | Jan Kiszka | |
1118 | ad196a9d | Jan Kiszka | @example |
1119 | ad196a9d | Jan Kiszka | # on the host |
1120 | aa375206 | Aurelien Jarno | qemu -net user,hostfwd=tcp::5555-:23 [...] |
1121 | ad196a9d | Jan Kiszka | telnet localhost 5555 |
1122 | ad196a9d | Jan Kiszka | @end example |
1123 | ad196a9d | Jan Kiszka | |
1124 | ad196a9d | Jan Kiszka | Then when you use on the host @code{telnet localhost 5555}, you |
1125 | ad196a9d | Jan Kiszka | connect to the guest telnet server. |
1126 | 5824d651 | blueswir1 | |
1127 | c92ef6a2 | Jan Kiszka | @item guestfwd=[tcp]:@var{server}:@var{port}-@var{dev} |
1128 | 3c6a0580 | Jan Kiszka | Forward guest TCP connections to the IP address @var{server} on port @var{port} |
1129 | 3c6a0580 | Jan Kiszka | to the character device @var{dev}. This option can be given multiple times. |
1130 | ad196a9d | Jan Kiszka | |

1132 | ad196a9d | Jan Kiszka | |
1133 | ad196a9d | Jan Kiszka | Note: Legacy stand-alone options -tftp, -bootp, -smb and -redir are still |
1134 | ad196a9d | Jan Kiszka | processed and applied to -net user. Mixing them with the new configuration |
1135 | ad196a9d | Jan Kiszka | syntax gives undefined results. Their use for new applications is discouraged |
1136 | ad196a9d | Jan Kiszka | as they will be removed from future versions. |

1303 | 7273a2db | Matthew Booth | @option{parport}. |
1304 | 7273a2db | Matthew Booth | The specific backend will determine the applicable options. |
1305 | 7273a2db | Matthew Booth | |
1306 | 7273a2db | Matthew Booth | All devices must have an id, which can be any string up to 127 characters long. |
1307 | 7273a2db | Matthew Booth | It is used to uniquely identify this device in other command line directives. |

1319 | 7273a2db | Matthew Booth | @item -chardev socket ,id=@var{id} [@var{TCP options} or @var{unix options}] [,server] [,nowait] [,telnet] |
1320 | 7273a2db | Matthew Booth | |
1321 | 7273a2db | Matthew Booth | Create a two-way stream socket, which can be either a TCP or a unix socket. A |
1322 | 7273a2db | Matthew Booth | unix socket will be created if @option{path} is specified. Behaviour is |
1323 | 7273a2db | Matthew Booth | undefined if TCP options are specified for a unix socket. |
1324 | 7273a2db | Matthew Booth | |
1325 | 7273a2db | Matthew Booth | @option{server} specifies that the socket shall be a listening socket. |
1326 | 7273a2db | Matthew Booth | |

1349 | 7273a2db | Matthew Booth | @option{port} cannot be bound, QEMU will attempt to bind to subsequent ports up |
1350 | 7273a2db | Matthew Booth | to and including @option{to} until it succeeds. @option{to} must be specified |
1351 | 7273a2db | Matthew Booth | as a port number. |
1352 | 7273a2db | Matthew Booth | |
1353 | 7273a2db | Matthew Booth | @option{ipv4} and @option{ipv6} specify that either IPv4 or IPv6 must be used. |

1654 | 5824d651 | blueswir1 | When @var{remote_host} or @var{src_ip} are not specified |
1655 | 5824d651 | blueswir1 | they default to @code{0.0.0.0}. |
1656 | 5824d651 | blueswir1 | When not using a specified @var{src_port} a random port is automatically chosen. |
1657 | 5824d651 | blueswir1 | |
1658 | 5824d651 | blueswir1 | If you just want a simple readonly console you can use @code{netcat} or |
1659 | 5824d651 | blueswir1 | @code{nc}, by starting qemu with: @code{-serial udp::4555} and nc as: |
1660 | 5824d651 | blueswir1 | @code{nc -u -l -p 4555}. Any time qemu writes something to that port it |
1661 | 5824d651 | blueswir1 | will appear in the netconsole session. |
1662 | 5824d651 | blueswir1 | |
1663 | 5824d651 | blueswir1 | If you plan to send characters back via netconsole or you want to stop |
1664 | 5824d651 | blueswir1 | and start qemu a lot of times, you should have qemu use the same |
1665 | 5824d651 | blueswir1 | source port each time by using something like @code{-serial |
1666 | 5824d651 | blueswir1 | udp::4555@@:4556} to qemu. Another approach is to use a patched |
1667 | 5824d651 | blueswir1 | version of netcat which can listen to a TCP port and send and receive |
1668 | 5824d651 | blueswir1 | characters via udp. If you have a patched version of netcat which |
1669 | 5824d651 | blueswir1 | activates telnet remote echo and single char transfer, then you can |
1670 | 5824d651 | blueswir1 | use the following options to step up a netcat redirector to allow |
1671 | 5824d651 | blueswir1 | telnet on port 5555 to access the qemu port. |

1682 | 5824d651 | blueswir1 | The TCP Net Console has two modes of operation. It can send the serial |
1683 | 5824d651 | blueswir1 | I/O to a location or wait for a connection from a location. By default |
1684 | 5824d651 | blueswir1 | the TCP Net Console is sent to @var{host} at the @var{port}. If you use |
1685 | 5824d651 | blueswir1 | the @var{server} option QEMU will wait for a client socket application |
1686 | 5824d651 | blueswir1 | to connect to the port before continuing, unless the @code{nowait} |
1687 | 5824d651 | blueswir1 | option was specified. The @code{nodelay} option disables the Nagle buffering |
1688 | 5824d651 | blueswir1 | algorithm. If @var{host} is omitted, 0.0.0.0 is assumed. Only |
1689 | 5824d651 | blueswir1 | one TCP connection at a time is accepted. You can use @code{telnet} to |

1702 | 5824d651 | blueswir1 | work the same as if you had specified @code{-serial tcp}. The |
1703 | 5824d651 | blueswir1 | difference is that the port acts like a telnet server or client using |
1704 | 5824d651 | blueswir1 | telnet option negotiation. This will also allow you to send the |
1705 | 5824d651 | blueswir1 | MAGIC_SYSRQ sequence if you use a telnet that supports sending the break |
1706 | 5824d651 | blueswir1 | sequence. Typically in unix telnet you do it with Control-] and then |

2038 | 9dd986cc | Richard W.M. Jones | The @var{model} is the model of hardware watchdog to emulate. Choices |
2039 | 9dd986cc | Richard W.M. Jones | for model are: @code{ib700} (iBASE 700) which is a very simple ISA |
2040 | 9dd986cc | Richard W.M. Jones | watchdog with a single timer, or @code{i6300esb} (Intel 6300ESB I/O |
2041 | 9dd986cc | Richard W.M. Jones | controller hub) which is a much more featureful PCI-based dual-timer |
2042 | 9dd986cc | Richard W.M. Jones | watchdog. Choose a model for which your guest has drivers. |
2043 | 9dd986cc | Richard W.M. Jones | |

2055 | 9dd986cc | Richard W.M. Jones | The @var{action} controls what QEMU will do when the watchdog timer |
2056 | 9dd986cc | Richard W.M. Jones | expires. |
2057 | 9dd986cc | Richard W.M. Jones | The default is |
2058 | 9dd986cc | Richard W.M. Jones | @code{reset} (forcefully reset the guest). |
2059 | 9dd986cc | Richard W.M. Jones | Other possible actions are: |
2060 | 9dd986cc | Richard W.M. Jones | @code{shutdown} (attempt to gracefully shutdown the guest), |
2061 | 9dd986cc | Richard W.M. Jones | @code{poweroff} (forcefully poweroff the guest), |
2062 | 9dd986cc | Richard W.M. Jones | @code{pause} (pause the guest), |
2063 | 9dd986cc | Richard W.M. Jones | @code{debug} (print a debug message and continue), or |
2064 | 9dd986cc | Richard W.M. Jones | @code{none} (do nothing). |
2065 | 9dd986cc | Richard W.M. Jones | |
2066 | 9dd986cc | Richard W.M. Jones | Note that the @code{shutdown} action requires that the guest responds |
2067 | 9dd986cc | Richard W.M. Jones | to ACPI signals, which it may not be able to do in the sort of |
