Here's a respind of my first pull request for qemu-2.10, consisting of
 assorted patches which have accumulated while qemu-2.9 stabilized.
 Highlights are:
     * Rework / cleanup of the XICS interrupt controller
     * Substantial improvement to the 'powernv' machine type
         - Includes an MMIO XICS version
     * POWER9 support improvements
         - POWER9 guests with KVM
         - Partial support for POWER9 guests with TCG
     * IOMMU and VFIO improvements
     * Assorted minor changes
 
 There are several IPMI patches here that aren't usually in my area of
 maintenance, but there isn't a regular maintainer and these patches
 are for the benefit of the powernv machine type.
 
 This pull request supersedes my 2017-04-26 pull request.  This new set
 fixes a bug in one of the aforementioned IPMI patches which caused
 clang sanitizer failures (and may have crashed on some libc / host
 versions).

540c07d345 ipmi: provide support for FRUs
This patch provides a simple FRU support for the BMC simulator. FRUs
are loaded from a file which name is specified in the object
properties, each entry having a fixed size, also specified in the
properties. If the file is unknown or not accessible for some reason,
a unique entry of 1024 bytes is created as a default. Just enough to
start some simulation.

These commands complies with the IPMI spec : "34. FRU Inventory Device
Commands".

8c6fd7f341 ipmi: use a file to load SDRs
The IPMI BMC simulator populates the sdr/sensor tables with a minimal
set of entries (Watchdog). But some qemu platforms might want to use
extra entries for their custom needs.

This patch modifies slighty the initializing routine to take into
account a larger set read from a file. The name of the file to use is
defined through a new 'sdr' property of the simulator device.

1c599472b0 xen: use libxendevice model to restrict operations
This patch adds a command-line option (-xen-domid-restrict) which will
use the new libxendevicemodel API to restrict devicemodel [1] operations
to the specified domid. (Such operations are not applicable to the xenpv
machine type).

This patch also adds a tracepoint to allow successful enabling of the
restriction to be monitored.

[1] I.e. operations issued by libxendevicemodel. Operation issued by other
    xen libraries (e.g. libxenforeignmemory) are currently still unrestricted
    but this will be rectified by subsequent patches.

42e5f39378 block: Initial implementation of -blockdev
The new command line option -blockdev works like QMP command
blockdev-add.

The option argument may be given in JSON syntax, exactly as in QMP.
Example usage:

    -blockdev '{"node-name": "foo", "driver": "raw", "file": {"driver": "file", "filename": "foo.img"} }'

The JSON argument doesn't exactly blend into the existing option
syntax, so the traditional KEY=VALUE,... syntax is also supported,
using dotted keys to do the nesting:

    -blockdev node-name=foo,driver=raw,file.driver=file,file.filename=foo.img

This does not yet support lists, but that will be addressed shortly.

Note that calling qmp_blockdev_add() (say via qmp_marshal_block_add())
right away would crash.  We need to stash the configuration for later
instead.  This is crudely done, and bypasses QemuOpts, even though
storing configuration is what QemuOpts is for.  Need to revamp option
infrastructure to support QAPI types like BlockdevOptions.

f778a82f0c hw/i386: Deprecate -drive if=scsi with PC machine types
The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically
create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi.
For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU
create 25 of them.

lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and
currently has no maintainer in QEMU.  megasas is a better choice,
except with old OSes that lack drivers.  virtio-scsi is a much better
choice when you have a driver, but only (newish) Linux comes with one
in the box.  There is no good default that works for all guests.

Encourage users to pick a non-obsolete SCSI HBA that works for them by
deprecating -drive if=scsi.

275e0d616b ui: refactor code for populating SocketAddress from vnc_display_open
The code which interprets the CLI args to populate the SocketAddress
objects for plain & websockets VNC is quite complex already and will
need further enhancements shortly. Refactor it into separate methods
to avoid vnc_display_open getting even larger. As a side effect of
the refactoring, it is now possible to specify a listen address for
the websocket server explicitly. e.g,

  -vnc localhost:5900,websockets=0.0.0.0:8080

will listen on localhost for the plain VNC server, but expose the
websockets VNC server on the public interface. This refactoring
also removes the restriction that prevents enabling websockets
when the plain VNC server is listening on a UNIX socket.

Use @var{firstcpu} and @var{lastcpu} to make the metasyntatic

the metasyntatic variables, not including the square brackets and
hyphen.

The semantics of the "cpus" option will be clarified by rewriting
the whole -numa documentation in a follow-up patch.

23dce3873f block/curl: Drop TFTP "support"
Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.

Therefore, it should be safe to just drop it from curl's protocol list.

[Jeff Cody: Below is additional summary pulled, with some rewording,
            from followup emails between Max and Markus, to explain what
            worked and what didn't]

TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero.  By default,
that readahead size is 256KB.

Reads starting at a non-zero offset would also have returned data from a
zero offset.  It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.

In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

37146e7eaf vl.c: Add '-L help' which lists data dirs.
QEMU compiles a list of data directories from various sources.  When
consuming a QEMU binary it's useful to be able to get this list of
data directories: a primary reason is so you can list what BIOSes or
keymaps ship with this version of QEMU.  However without reproducing
the method that QEMU uses internally, it's not possible to get the
list of data directories.

This commit adds a simple '-L help' option that just lists out the
data directories as qemu calculates them:

$ ./x86_64-softmmu/qemu-system-x86_64 -L help
/home/rjones/d/qemu/pc-bios
/usr/local/share/qemu

$ ./x86_64-softmmu/qemu-system-x86_64 -L /tmp -L help
/tmp
/home/rjones/d/qemu/pc-bios

63d3145aad fw_cfg: Adopt /opt/RFQDN convention
FW CFG's primary user is QEMU, which uses it to expose configuration
information (in the widest sense) to Firmware.  Thus the name FW CFG.

FW CFG can also be used by others for their own purposes.  QEMU is
merely acting as transport then.  Names starting with opt/ are
reserved for such uses.  There is no provision, however, to guide safe
sharing among different such users.

Fix that, loosely following QMP precedence: names should start with
opt/RFQDN/, where RFQDN is a reverse fully qualified domain name you
control.

Based on a more ambitious patch from Michael Tsirkin.

When debugging big programs or system emulation sometimes you want both
the verbosity of cpu,exec et all but don't want to generate lots of logs
for unneeded stuff. This patch adds a new option -dfilter which allows
you to specify interesting address ranges in the form:

  -dfilter 0x8000..0x8fff,0xffffffc000080000+0x200,...

Then logging code can use the new qemu_log_in_addr_range() function to
decide if it will output logging information for the given range.

e0d2bd5195 input: linux evdev support
This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest.  Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.

Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle.  Also there is no support for
absolute coordinates (tablet/touchscreen).  So we are talking here about
basic mouse and keyboard support.

The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have).  And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.

Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.

Usage:  Add '-input-linux /dev/input/event<nr>' to the qemu command
line.  Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

902c053d83 migration: allow machine to enforce configuration section migration
Migration of pseries-2.3 doesn't have configuration section. Unfortunately,
QEMU 2.4/2.4.1/2.5 are buggy and always stream and expect the configuration
section, and break migration both ways.

This patch introduces a property which allows to enforce a configuration
section for machines who don't have one.

It can be set at startup:

-machine enforce-config-section=on

or later from the QEMU monitor:

qom-set /machine enforce-config-section on

It is up to the tooling to set or unset this property according to the
version of the QEMU at the other end of the pipe.

474114b730 spice: add opengl/virgl/dmabuf support
This adds support for dma-buf passing to spice.  This makes virtio-gpu
with 3d acceleration work with spice.

Workflow:
 * virglrenderer renders the guest command stream into a texture.
 * qemu exports the texture as dma-buf and passes on that dma-buf
   to spice-server.
 * spice-server passes the dma-buf to spice-client, using unix
   socket file descriptor passing.
 * spice-client asks the window systems composer to render the
   dma-buf to the screen.

Requires cutting edge spice (server) and spice-gtk (client) builds,
from git master branch.

Also requires libvirt managing your qemu instance, and using
"virt-viewer --attach $guest".  libvirt will connect spice-server and
spice-client using unix sockets instead of tcp sockets then, which
is required for file descriptor passing.

Works for the local case (spice server and client on the same machine)
only.  Supporting remote too is planned (by feeding the dma-bufs into
gpu-assisted video encoder), but not there yet.

gl mode is turned off by default, use "-spice gl=on,$otherargs" to
enable it.

The Microsoft spec about the SLIC and MSDM ACPI tables at
<http://go.microsoft.com/fwlink/p/?LinkId=234834> requires the OEM ID and
OEM Table ID fields to be consistent between the SLIC and the RSDT/XSDT.
That further affects the FADT, because a similar match between the FADT
and the RSDT/XSDT is required by the ACPI spec in general.

This patch wires up the previous three patches.

a8fb542705 char: introduce support for TLS encrypted TCP chardev backend
This integrates support for QIOChannelTLS object in the TCP
chardev backend. If the 'tls-creds=NAME' option is passed with
the '-chardev tcp' argument, then it will setup the chardev
such that the client is required to establish a TLS handshake
when connecting. There is no support for checking the client
certificate against ACLs in this initial patch. This is pending
work to QOM-ify the ACL object code.

A complete invocation to run QEMU as the server for a TLS
encrypted serial dev might be

  $ qemu-system-x86_64 \
      -nodefconfig -nodefaults -device sga -display none \
      -chardev socket,id=s0,host=127.0.0.1,port=9000,tls-creds=tls0,server \
      -device isa-serial,chardev=s0 \
      -object tls-creds-x509,id=tls0,endpoint=server,verify-peer=off,\
         dir=/home/berrange/security/qemutls

To test with the gnutls-cli tool as the client:

  $ gnutls-cli --priority=NORMAL -p 9000 \
       --x509cafile=/home/berrange/security/qemutls/ca-cert.pem \
       127.0.0.1

If QEMU was told to use 'anon' credential type, then use the
priority string 'NORMAL:+ANON-DH' with gnutls-cli

Alternatively, if setting up a chardev to operate as a client,
then the TLS credentials registered must be for the client
endpoint. First a TLS server must be setup, which can be done
with the gnutls-serv tool

  $ gnutls-serv --priority=NORMAL -p 9000 --echo \
       --x509cafile=/home/berrange/security/qemutls/ca-cert.pem \
       --x509certfile=/home/berrange/security/qemutls/server-cert.pem \
       --x509keyfile=/home/berrange/security/qemutls/server-key.pem

Then QEMU can connect with

  $ qemu-system-x86_64 \
      -nodefconfig -nodefaults -device sga -display none \
      -chardev socket,id=s0,host=127.0.0.1,port=9000,tls-creds=tls0 \
      -device isa-serial,chardev=s0 \
      -object tls-creds-x509,id=tls0,endpoint=client,\
        dir=/home/berrange/security/qemutls

d0d7708ba2 qemu-char: add logfile facility to all chardev backends
Typically a UNIX guest OS will log boot messages to a serial
port in addition to any graphical console. An admin user
may also wish to use the serial port for an interactive
console. A virtualization management system may wish to
collect system boot messages by logging the serial port,
but also wish to allow admins interactive access.

Currently providing such a feature forces the mgmt app
to either provide 2 separate serial ports, one for
logging boot messages and one for interactive console
login, or to proxy all output via a separate service
that can multiplex the two needs onto one serial port.
While both are valid approaches, they each have their
own downsides. The former causes confusion and extra
setup work for VM admins creating disk images. The latter
places an extra burden to re-implement much of the QEMU
chardev backends logic in libvirt or even higher level
mgmt apps and adds extra hops in the data transfer path.

A simpler approach that is satisfactory for many use
cases is to allow the QEMU chardev backends to have a
"logfile" property associated with them.

 $QEMU -chardev socket,host=localhost,port=9000,\
                server=on,nowait,id-charserial0,\
		logfile=/var/log/libvirt/qemu/test-serial0.log
       -device isa-serial,chardev=charserial0,id=serial0

This patch introduces a 'ChardevCommon' struct which
is setup as a base for all the ChardevBackend types.
Ideally this would be registered directly as a base
against ChardevBackend, rather than each type, but
the QAPI generator doesn't allow that since the
ChardevBackend is a non-discriminated union. The
ChardevCommon struct provides the optional 'logfile'
parameter, as well as 'logappend' which controls
whether QEMU truncates or appends (default truncate).

87252e1b61 nvdimm acpi: build ACPI NFIT table
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)

Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info

- MEM DEV structure, it has the @handle which is used to associate specified
  ACPI NVDIMM  device we will introduce in later patch.
  Also we can happily ignored the memory device's interleave, the real
  nvdimm hardware access is hidden behind host

- DCR structure, it defines vendor ID used to associate specified vendor
  nvdimm driver. Since we only implement PMEM mode this time, Command
  window and Data window are not needed

The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100  -object \
memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \
nvdimm,memdev=mem1,id=nv1

It is disabled on default

1d7b5b4afd crypto: add support for loading encrypted x509 keys
Make use of the QCryptoSecret object to support loading of
encrypted x509 keys. The optional 'passwordid' parameter
to the tls-creds-x509 object type, provides the ID of a
secret object instance that holds the decryption password
for the PEM file.

 # printf "123456" > mypasswd.txt
 # $QEMU \
    -object secret,id=sec0,filename=mypasswd.txt \
    -object tls-creds-x509,passwordid=sec0,id=creds0,\
            dir=/home/berrange/.pki/qemu,endpoint=server \
    -vnc :1,tls-creds=creds0

This requires QEMU to be linked to GNUTLS >= 3.1.11. If
GNUTLS is too old an error will be reported if an attempt
is made to pass a decryption password.

ac1d887849 crypto: add QCryptoSecret object class for password/key handling
Introduce a new QCryptoSecret object class which will be used
for providing passwords and keys to other objects which need
sensitive credentials.

The new object can provide secret values directly as properties,
or indirectly via a file. The latter includes support for file
descriptor passing syntax on UNIX platforms. Ordinarily passing
secret values directly as properties is insecure, since they
are visible in process listings, or in log files showing the
CLI args / QMP commands. It is possible to use AES-256-CBC to
encrypt the secret values though, in which case all that is
visible is the ciphertext.  For ad hoc developer testing though,
it is fine to provide the secrets directly without encryption
so this is not explicitly forbidden.

The anticipated scenario is that libvirtd will create a random
master key per QEMU instance (eg /var/run/libvirt/qemu/$VMNAME.key)
and will use that key to encrypt all passwords it provides to
QEMU via '-object secret,....'.  This avoids the need for libvirt
(or other mgmt apps) to worry about file descriptor passing.

It also makes life easier for people who are scripting the
management of QEMU, for whom FD passing is significantly more
complex.

Providing data inline (insecure, only for ad hoc dev testing)

  $QEMU -object secret,id=sec0,data=letmein

Providing data indirectly in raw format

  printf "letmein" > mypasswd.txt
  $QEMU -object secret,id=sec0,file=mypasswd.txt

Providing data indirectly in base64 format

  $QEMU -object secret,id=sec0,file=mykey.b64,format=base64

Providing data with encryption

  $QEMU -object secret,id=master0,file=mykey.b64,format=base64 \
        -object secret,id=sec0,data=[base64 ciphertext],\
	           keyid=master0,iv=[base64 IV],format=base64

Note that 'format' here refers to the format of the ciphertext
data. The decrypted data must always be in raw byte format.

More examples are shown in the updated docs.

MicroCheckpointing or other Remus like VM FT solutions.
You can also use it to crudely simulate network delay.  Doesn't

a delay of sorts.

Usage:
 -netdev tap,id=bn0
 -object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000

 Interval is in microseconds, it can't be omitted currently, and can't be 0.

b931bfbf04 vhost-user: add multiple queue support
This patch is initially based a patch from Nikolay Nikolaev.

This patch adds vhost-user multiple queue support, by creating a nc
and vhost_net pair for each queue.

Qemu exits if find that the backend can't support the number of requested
queues (by providing queues=# option). The max number is queried by a
new message, VHOST_USER_GET_QUEUE_NUM, and is sent only when protocol
feature VHOST_USER_PROTOCOL_F_MQ is present first.

The max queue check is done at vhost-user initiation stage. We initiate
one queue first, which, in the meantime, also gets the max_queues the
backend supports.

In older version, it was reported that some messages are sent more times
than necessary. Here we came an agreement with Michael that we could
categorize vhost user messages to 2 types: non-vring specific messages,
which should be sent only once, and vring specific messages, which should
be sent per queue.

Here I introduced a helper function vhost_user_one_time_request(), which
lists following messages as non-vring specific messages:

        VHOST_USER_SET_OWNER
        VHOST_USER_RESET_DEVICE
        VHOST_USER_SET_MEM_TABLE
        VHOST_USER_GET_QUEUE_NUM

For above messages, we simply ignore them when they are not sent the first
time.

3e305e4a47 ui: convert VNC server to use QCryptoTLSSession
Switch VNC server over to using the QCryptoTLSSession object
for the TLS session. This removes the direct use of gnutls
from the VNC server code. It also removes most knowledge
about TLS certificate handling from the VNC server code.
This has the nice effect that all the CONFIG_VNC_TLS
conditionals go away and the user gets an actual error
message when requesting TLS instead of it being silently
ignored.

With this change, the existing configuration options for
enabling TLS with -vnc are deprecated.

Old syntax for anon-DH credentials:

  -vnc hostname:0,tls

New syntax:

  -object tls-creds-anon,id=tls0,endpoint=server \
  -vnc hostname:0,tls-creds=tls0

Old syntax for x509 credentials, no client certs:

  -vnc hostname:0,tls,x509=/path/to/certs

New syntax:

  -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=no \
  -vnc hostname:0,tls-creds=tls0

Old syntax for x509 credentials, requiring client certs:

  -vnc hostname:0,tls,x509verify=/path/to/certs

New syntax:

  -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=yes \
  -vnc hostname:0,tls-creds=tls0

This aligns VNC with the way TLS credentials are to be
configured in the future for chardev, nbd and migration
backends. It also has the benefit that the same TLS
credentials can be shared across multiple VNC server
instances, if desired.

If someone uses the deprecated syntax, it will internally
result in the creation of a 'tls-creds' object with an ID
based on the VNC server ID. This allows backwards compat
with the CLI syntax, while still deleting all the original
TLS code from the VNC server.

libiscsi starting with 1.15 will properly support timeout of iscsi
commands. The default will remain no timeout, but this can
be changed via cmdline parameters, e.g.:

qemu -iscsi timeout=30 -drive file=iscsi://...

If a timeout occurs a reconnect is scheduled and the timed out command
will be requeued for processing after a successful reconnect.

The required API call iscsi_set_timeout is present since libiscsi
1.10 which was released in October 2013. However, due to some bugs
in the libiscsi code the use is not recommended before version 1.15.

Please note that this patch bumps the libiscsi requirement to 1.10
to have all function and macros defined. The patch fixes also a
off-by-one error in the NOP timeout calculation which was fixed
while touching these code parts.

a59d31a1eb semihosting: add --semihosting-config arg sub-argument
Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.

Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).

If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

76f4afb40f throttle: Add throttle group support
The throttle group support use a cooperative round robin scheduling
algorithm.

The principles of the algorithm are simple:
- Each BDS of the group is used as a token in a circular way.
- The active BDS computes if a wait must be done and arms the right
  timer.
- If a wait must be done the token timer will be armed so the token
  will become the next active BDS.

other watchdogs, monitor a guest and take corresponding actions when it
detects that the guest is not responding.

diag288 is s390x specific. The wiring to s390x KVM will be done in

exit with an error message if the user supplies multiple

collides with a fw_cfg name programmatically added from
within the QEMU source code. A warning message will be
printed if the fw_cfg item name does not begin with the

0daba1f037 machine: Drop use of DEFAULT_RAM_SIZE in help text
As of commit 076b35b5a (machine: add default_ram_size to machine
class) we no longer have a global default ram size, but instead
machine specific defaults.  When invoking qemu --help we don't know
which machine you selected, so we can't tell the user the default RAM
size in the help text anymore now.

Thus I don't see an easy way to expose the default ram size to the
user in the help text.  The easiest option IMHO is to just drop this
piece of information.

3751d7c43f vl: allow full-blown QemuOpts syntax for -global
-global does not work for drivers that have a dot in their name, such as
cfi.pflash01.  This is just a parsing limitation, because such globals
can be declared easily inside a -readconfig file.

To allow this usage, support the full QemuOpts key/value syntax for -global
too, for example "-global driver=cfi.pflash01,property=secure,value=on".
The two formats do not conflict, because the key/value syntax does not have
a period before the first equal sign.

6a8b4a5be2 net: Change help text to list -netdev instead of -net by default
Looking at the output of "qemu-system-xxx -help", you easily get
the impression that "-net" is the preferred way instead of "-netdev"
to specify host network interface, since the "-net" option is
omnipresent but the "-netdev" option is only listed as a one-liner
at the end. This is ugly since "-net" is considered as legacy and
even might be removed one day. Thus, this patch switches the output
to explain the host network interfaces with the "-netdev" option
instead, moving the old "-net" option into some few lines at
the end.

Check for the aes_key_wrap and dea_key_wrap machine options and set the

This patch introduces two new machine options for indicating the state of
AES/DEA key wrapping functions.  This controls whether the guest will
have access to the AES/DEA crypto functions.

aes_key_wrap="on | off" is changed to aes-key-wrap="on | off"
dea_key_wrap="on | off" is changed to dea-key-wrap="on | off"

Check for the aes-key-wrap and dea-key-wrap machine options and set the

a38bb0792c Add the "-semihosting-config" option.
The usual semihosting behaviour is to process the system calls locally and
return; unfortuantelly the initial implementation dinamically changed the
target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb,
is not implemented. The result was that during debug sessions the semihosting
calls were discarded.

This patch adds a configuration variable and an option to set it on the
command line:

    -semihosting-config [enable=on|off,]target=native|gdb|auto

This option enables semihosting and defines where the semihosting calls will
be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which
means 'gdb' during debug sessions and 'native' otherwise.

1. It silently ignores -clock for backward compatibility.
Incompatible change: -clock help no longer terminates the program.
Tolerable.

2. Failed to update option documentation.  In particular, -help still
advises users to try -clock help for available timers.  Drop all
documentation on -clock.

5cd1475d28 s390x/kvm: Several updates/fixes/features
1. s390x/kvm: avoid synchronize_rcu's in kernel
 ----------------------------------------------
 The first patches change s390x/kvm code to issue VCPU specific ioctls
 from the VCPU thread. This will avoid unnecessary synchronize_rcu in
 the kernel, which caused a noticably slowdown with many guest CPUs.
 It speeds up all start/restart/reset operations involving cpus
 drastically.
 
 2. s390-ccw.img: block size and DASD format support
 ---------------------------------------------------
 The second part changes the s390-ccw bios to IPL (boot)  more disk
 formats than before. Furthermore a small fix is made to the console
 output of the bios.
 
 3. s390: Support for Hotplug of Standby Memory
 ----------------------------------------------
 The third part adds support in s390 for a pool of standby memory,
 which can be set online/offline by the guest (ie, via chmem).
 The standby pool of memory is allocated as the difference between
 the initial memory setting and the maxmem setting.
 As part of this work, additional results are provided for the
 Read SCP Information SCLP, and new implentation is added for the
 Read Storage Element Information, Attach Storage Element,
 Assign Storage and Unassign Storage SCLPs, which enables the s390
 guest to manipulate the standby memory pool.
 
 This patchset is based on work originally done by Jeng-Fang (Nick)
 Wang.
 
 Sample qemu command snippet:
 
 qemu -machine s390-ccw-virtio  -m 1024M,maxmem=2048M,slots=32 -enable-kvm
 
 This will allocate 1024M of active memory, and another 1024M
 of standby memory.  Example output from s390-tools lsmem:
 =============================================================================
 0x0000000000000000-0x000000000fffffff        256  online   no         0-127
 0x0000000010000000-0x000000001fffffff        256  online   yes        128-255
 0x0000000020000000-0x000000003fffffff        512  online   no         256-511
 0x0000000040000000-0x000000007fffffff       1024  offline  -          512-1023
 
 Memory device size  : 2 MB
 Memory block size   : 256 MB
 Total online memory : 1024 MB
 Total offline memory: 1024 MB
 
 The guest can dynamically enable part or all of the standby pool
 via the s390-tools chmem, for example:
 
 chmem -e 512M
 
 And can attempt to dynamically disable:
 
 chmem -d 512M
 
 4. s390x/gdb: various fixes
 ---------------------------
 * Patch 1 fixes a bug where the cc was changed accidentally.
 * Patch 2 adds the gdb feature XML files for s390x
 * Patch 3 Define acr and fpr registers as coprocessor registers. This allows us
    to reuse the feature XML files.
 * Patch 4 whitespace fixes

a94f83d94f curl: Allow a cookie or cookies to be sent with http/https requests.
In order to access VMware ESX efficiently, we need to send a session
cookie.  This patch is very simple and just allows you to send that
session cookie.  It punts on the question of how you get the session
cookie in the first place, but in practice you can just run a `curl'
command against the server and extract the cookie that way.

To use it, add file.cookie to the curl URL.  For example:

$ qemu-img info 'json: {
    "file.driver":"https",
    "file.url":"https://vcenter/folder/Windows%202003/Windows%202003-flat.vmdk?dcPath=Datacenter&dsName=datastore1",

The curl hardcoded timeout (5 seconds) sometimes is not long
enough depending on the remote server configuration and network
traffic. The user should be able to set how much long he is
willing to wait for the connection.

Adding a new option to set this timeout gives the user this
flexibility. The previous default timeout of 5 seconds will be
used if this option is not present.

abfd9ce341 migration: dump vmstate info as a json file for static analysis
This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument.  When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.

The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.

A Python script that compares the output of such JSON dumps is included
in the following commit.

a socket backend, with a set path (i.e. a Unix socket) and optionally
the server parameter set, will be allowed. Other options (nowait, telnet)
will make the chardev unusable and the netdev will not be initialised.

Additional checks for validity:
  - requires `-numa node,memdev=..`
  - requires `-device virtio-net-*`

The `vhostforce` option is used to force vhost-net when we deal with

this patch tries to optimize zero write requests

usually it is better to re-phrase the statement.

58952137b0 net: Adding netmap network backend
This patch adds support for a network backend based on netmap.
netmap is a framework for high speed packet I/O. You can use it
to build extremely fast traffic generators, monitors, software
switches or network middleboxes. Its companion software switch
VALE lets you interconnect virtual machines.
netmap and VALE are implemented as a non-intrusive kernel module,
support NICs from multiple vendors, are part of standard FreeBSD
distributions and available in source format for Linux too.

To compile QEMU with netmap support, use the following configure
options:
    ./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys
where "/path/to/netmap" contains the netmap source code, available at
    http://info.iet.unipi.it/~luigi/netmap/

The same webpage contains more information about the netmap project
(together with papers and presentations).

4f57378fe6 Revert "chardev: Make the name of memory device consistent"
This reverts commit 6a85e60cb9.

Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver"
introduced a memory ring buffer character device driver named
"memory".  Commit 3949e59 "qemu-char: Saner naming of memchar stuff &
doc fixes" changed the driver name to "ringbuf", along with a whole
bunch of other names, with the following rationale:

    Naming is a mess.  The code calls the device driver
    CirMemCharDriver, the public API calls it "memory", "memchardev",
    or "memchar", and the special commands are named like
    "memchar-FOO".  "memory" is a particularly unfortunate choice,
    because there's another character device driver called
    MemoryDriver.  Moreover, the device's distinctive property is that
    it's a ring buffer, not that's in memory.

This is what we released in 1.4.0.

Unfortunately, the rename missed a critical instance of "memory": the
actual driver name.  Thus, the new device could be used only by an
entirely undocumented name.  The documented name did not work.
Bummer.

Commit 6a85e60 fixes this by changing the documentation to match the
code.  It also changes some, but not all related occurences of
"ringbuf" to "memory".  Left alone are identifiers in C code, HMP and
QMP commands.  The latter are external interface, so they can't be
changed.

The result is an inconsistent mess.  Moreover, "memory" is a rotten
name.  The device's distinctive property is that it's a ring buffer,
not that's in memory.  User's don't care whether it's in RAM, flash,
or carved into chocolate tablets by Oompa Loompas.

Revert the commit.  Next commit will fix just the bug.

5e2ac51917 add timestamp to error_report()
[Issue]
When we offer a customer support service and a problem happens
in a customer's system, we try to understand the problem by
comparing what the customer reports with message logs of the
customer's system.

In this case, we often need to know when the problem happens.

But, currently, there is no timestamp in qemu's error messages.
Therefore, we may not be able to understand the problem based on
error messages.

[Solution]
Add a timestamp to qemu's error message logged by
error_report() with g_time_val_to_iso8601().

02c4bdf1d2 trap signals for "-serial mon:stdio"
With mon:stdio you can exit the VM by switching to the monitor and
sending the "quit" command.  It is then useful to pass Ctrl-C to the
VM instead of exiting.

This in turn lets us stop tying the default signal handling behavior
to -nographic, removing gratuitous differences between "-display none"
and "-nographic".

This patch changes behavior for "-display none -serial mon:stdio", as
expected, but not for "-display none -serial stdio".

12b7f57e2c vl: convert -smp to qemu_opts_parse()
This also introduces a new suboption, "cpus=",
which is the default.  So after this patch,

 -smp n,sockets=y

is the same as

  -smp cpus=n,sockets=y

(with "cpu" being some generic thing, referring to
either cores, or threads, or sockets, as before).

We still don't validate relations between different
numbers, for example it is still possible to say

  -smp 1,sockets=10

and it will be accepted to mean sockets=1.

0057a0d590 TLS support for VNC Websockets
Added TLS support to the VNC QEMU Websockets implementation.
VNC-TLS needs to be enabled for this feature to be used.

The required certificates are specified as in case of VNC-TLS
with the VNC parameter "x509=<path>".

If the server certificate isn't signed by a rooth authority it needs to
be manually imported in the browser because at least in case of Firefox
and Chrome there is no user dialog, the connection just gets canceled.

As a side note VEncrypt over Websocket doesn't work atm because TLS can't
be stacked in the current implementation. (It also didn't work before)
Nevertheless to my knowledge there is no HTML 5 VNC client which supports
it and the Websocket connection can be encrypted with regular TLS now so
it should be fine for most use cases.

0a12ec87a5 block: Add support for Secure Shell (ssh) block device.
qemu-system-x86_64 -drive file=ssh://hostname/some/image

QEMU will ssh into 'hostname' and open '/some/image' which is made
available as a standard block device.

You can specify a username (ssh://user@host/...) and/or a port number
(ssh://host:port/...).  You can also use an alternate syntax using
properties (file.user, file.host, file.port, file.path).

Current limitations:

- Authentication must be done without passwords or passphrases, using
  ssh-agent.  Other authentication methods are not supported.

- Uses a single connection, instead of concurrent AIO with multiple
  SSH connections.

This is implemented using libssh2 on the client side.  The server just
requires a regular ssh daemon with sftp-server support.  Most ssh
daemons on Unix/Linux systems will work out of the box.

92dcc234ec Add support for cancelling of a TPM command
This patch adds support for cancelling an executing TPM command.
In Linux for example a user can cancel a command through the TPM's
sysfs 'cancel' entry using

echo "1" > /sysfs/class/misc/tpm0/device/cancel

This patch propagates the cancellation of a command inside a VM
to the host TPM's sysfs entry.
It also uses the possibility to cancel the command before QEMU VM
shutdown or reboot, which helps in preventing QEMU from hanging while
waiting for the completion of the command.
To relieve higher layers or users from having to determine the TPM's
cancel sysfs entry, the driver searches for the entry in well known
locations.

4549a8b7ee Add a TPM Passthrough backend driver implementation
This patch is based of off version 9 of Stefan Berger's patch series
  "QEMU Trusted Platform Module (TPM) integration"
and adds a new backend driver for it.

This patch adds a passthrough backend driver for passing commands sent to the
emulated TPM device directly to a TPM device opened on the host machine.
Thus it is possible to use a hardware TPM device in a system running on QEMU,
providing the ability to access a TPM in a special state (e.g. after a Trusted
Boot).

This functionality is being used in the acTvSM Trusted Virtualization Platform
which is available on [1].

Usage example:
  qemu-system-x86_64 -tpmdev passthrough,id=tpm0,path=/dev/tpm0 \
                     -device tpm-tis,tpmdev=tpm0 \
                     -cdrom test.iso -boot d

Some notes about the host TPM:
The TPM needs to be enabled and activated. If that's not the case one
has to go through the BIOS/UEFI and enable and activate that TPM for TPM
commands to work as expected.
It may be necessary to boot the kernel using tpm_tis.force=1 in the boot
command line or 'modprobe tpm_tis force=1' in case of using it as a module.

Andreas Niederl, Stefan Berger

d1a0cf738d Support for TPM command line options
This patch adds support for TPM command line options.
The command line options supported here are

./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
           -device tpm-tis,tpmdev=<id>,id=<other id>

and

./qemu-... -tpmdev help

where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').

Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.

Monitor support for 'info tpm' has been added. It for example prints the
following:

(qemu) info tpm
TPM devices:
 tpm0: model=tpm-tis
  \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel

989b697ddd qemu-log: default to stderr for logging output
Switch the default for qemu_log logging output from "/tmp/qemu.log"
to stderr. This is an incompatible change in some sense, but logging
is mostly used for debugging purposes so it shouldn't affect production
use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log"
to the command line.

This change requires us to:
 * update all the documentation/help text (we take the opportunity
   to smooth out minor inconsistencies between the phrasing in
   linux-user/bsd-user/system help messages)
 * make linux-user and bsd-user defer to qemu-log for the default
   logging destination rather than overriding it themselves
 * ensure that all logfile closing is done via qemu_log_close()
   and that that function doesn't close stderr
as well as the obvious change to the behaviour of do_qemu_set_log()
when no logfile name has been specified.

special commands are named like "memchar-FOO".  "memory" is a
particularly unfortunate choice, because there's another character
device driver called MemoryDriver.  Moreover, the device's distinctive
property is that it's a ring buffer, not that's in memory.  Therefore:

* Rename CirMemCharDriver to RingBufCharDriver, and call the thing a
  "ringbuf" in the API.

* Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO.

* Rename device parameter from maxcapacity to size (simple words are
  good for you).

* Clearly mark the parameter as optional in documentation.

* Fix error reporting so that chardev-add reports to current monitor,
  not stderr.

* Replace cirmem in C identifiers by ringbuf.

* Rework documentation.  Document the impact of our crappy UTF-8
  handling on reading.

* QMP examples that even work.

I could split this up into multiple commits, but they'd change the
same documentation lines multiple times.  Not worth it.

7536ee4bc3 vnc: added initial websocket protocol support
This patch adds basic Websocket Protocol version 13 - RFC 6455 - support
to QEMU VNC. Binary encoding support on the client side is mandatory.

Because of the GnuTLS requirement the Websockets implementation is
optional (--enable-vnc-ws).

To activate Websocket support the VNC option "websocket"is used, for
example "-vnc :0,websocket".
The listen port for Websocket connections is (5700 + display) so if
QEMU VNC is started with :0 the Websocket port would be 5700.
As an alternative the Websocket port could be manually specified by
using ",websocket=<port>" instead.

Parts of the implementation base on Anthony Liguori's QEMU Websocket
patch from 2010 and on Joel Martin's LibVNC Websocket implementation.

587ed6be0b qemu-config: Add new -add-fd command line option
This option can be used for passing file descriptors on the
command line.  It mirrors the existing add-fd QMP command which
allows an fd to be passed to QEMU via SCM_RIGHTS and added to an
fd set.

This can be combined with commands such as -drive to link file
descriptors in an fd set to a drive:

    qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file"
             -add-fd fd=4,set=2,opaque="rdonly:/path/to/file"
             -drive file=/dev/fdset/2,index=0,media=disk

This example adds dups of fds 3 and 4, and the accompanying opaque
strings to the fd set with ID=2.  qemu_open() already knows how
to handle a filename of this format.  qemu_open() searches the
corresponding fd set for an fd and when it finds a match, QEMU
goes on to use a dup of that fd just like it would have used an
fd that it opened itself.

ac05f34924 add a boot parameter to set reboot timeout
Added an option to let qemu transfer a configuration file to bios,
"etc/boot-fail-wait", which could be specified by command
    -boot reboot-timeout=T
T have a max value of 0xffff, unit is ms.

With this option, guest will wait for a given time if not find
bootabled device, then reboot. If reboot-timeout is '-1', guest
will not reboot, qemu passes '-1' to bios by default.

This feature need the new seabios's support.

Seabios pulls the value from the fwcfg "file" interface, this
interface is used because SeaBIOS needs a reliable way of
obtaining a name, value size, and value. It in no way requires
that there be a real file on the user's host machine.

f278d4947f i8259: add -no-spurious-interrupt-hack option
This patch provides a way to optionally suppress spurious interrupts,
as a workaround for systems described below:

Some old operating systems do not handle spurious interrupts well,
and qemu tends to generate them significantly more often than
real hardware.

Examples:
  - Microport UNIX System V/386 v 2.1 (ca 1987)
    (The main problem I'm fixing: Without this patch, it panics
    sporadically when accessing the hard disk.)
  - AT&T UNIX System V/386 Release 4.0 Version 2.1a (ca 1991)
    See screenshot in "QEMU Official OS Support List":
    http://www.claunia.com/qemu/objectManager.php?sClass=application&iId=9
    (I don't have this system to test.)
