      spice: core bits · 29b0040b
      由 Gerd Hoffmann 提交于 
      Add -spice command line switch.  Has support setting passwd and port for
now.  With this patch applied the spice client can successfully connect
to qemu.  You can't do anything useful yet though.

      error: Track locations in configuration files · cf5a65aa
      由 Markus Armbruster 提交于 
      New LOC_FILE.  Use it for tracking file name and line number in
qemu_config_parse().  We now report errors like

    qemu:foo.conf:42: Did not find I2C bus for smbus-eeprom

In particular, gems like this message:

    -device: no driver specified

become almost nice now:

    qemu:foo.conf:44: -device: no driver specified

(A later commit will get rid of the bogus -device:)

      Add cpu model configuration support.. · b5ec5ce0
      由 john cooper 提交于 
      This is a reimplementation of prior versions which adds
the ability to define cpu models for contemporary processors.
The added models are likewise selected via -cpu <name>,
and are intended to displace the existing convention
of "-cpu qemu64" augmented with a series of feature flags.

A primary motivation was determination of a least common
denominator within a given processor class to simplify guest
migration.  It is still possible to modify an arbitrary model
via additional feature flags however the goal here was to
make doing so unnecessary in typical usage.  The other
consideration was providing models names reflective of
current processors.  Both AMD and Intel have reviewed the
models in terms of balancing generality of migration vs.
excessive feature downgrade relative to released silicon.

This version of the patch replaces the prior hard wired
definitions with a configuration file approach for new
models.  Existing models are thus far left as-is but may
easily be transitioned to (or may be overridden by) the
configuration file representation.

Proposed new model definitions are provided here for current
AMD and Intel processors.  Each model consists of a name
used to select it on the command line (-cpu <name>), and a
model_id which corresponds to a least common denominator
commercial instance of the processor class.

A table of names/model_ids may be queried via "-cpu ?model":

        :
    x86       Opteron_G3  AMD Opteron 23xx (Gen 3 Class Opteron)
    x86       Opteron_G2  AMD Opteron 22xx (Gen 2 Class Opteron)
    x86       Opteron_G1  AMD Opteron 240 (Gen 1 Class Opteron)
    x86          Nehalem  Intel Core i7 9xx (Nehalem Class Core i7)
    x86           Penryn  Intel Core 2 Duo P9xxx (Penryn Class Core 2)
    x86           Conroe  Intel Celeron_4x0 (Conroe/Merom Class Core 2)
        :

Also added is "-cpu ?dump" which exhaustively outputs all config
data for all defined models, and "-cpu ?cpuid" which enumerates
all qemu recognized CPUID feature flags.

The pseudo cpuid flag 'check' when added to the feature flag list
will warn when feature flags (either implicit in a cpu model or
explicit on the command line) would have otherwise been quietly
unavailable to a guest:

    # qemu-system-x86_64 ... -cpu Nehalem,check
    warning: host cpuid 0000_0001 lacks requested flag 'sse4.2|sse4_2' [0x00100000]
    warning: host cpuid 0000_0001 lacks requested flag 'popcnt' [0x00800000]

A similar 'enforce' pseudo flag exists which in addition
to the above causes qemu to error exit if requested flags are
unavailable.

Configuration data for a cpu model resides in the target config
file which by default will be installed as:

    /usr/local/etc/qemu/target-<arch>.conf

The format of this file should be self explanatory given the
definitions for the above six models and essentially mimics
the structure of the static x86_def_t x86_defs.

Encoding of cpuid flags names now allows aliases for both the
configuration file and the command line which reconciles some
Intel/AMD/Linux/Qemu naming differences.

This patch was tested relative to qemu.git.

      rework -monitor handling, switch to QemuOpts · 88589343
      由 Gerd Hoffmann 提交于 
      This patch reworks the -monitor handling:

 - It adds a new "mon" QemuOpts list for the monitor(s).
 - It adds a monitor_parse() function to parse the -monitor switch.
 - It adds a mon_init function to initialize the monitor(s) from the
   "mon" QemuOpts list.
 - It winds up everything and removes the old bits.

      qdev: add command line option to set global defaults for properties. · d0fef6fb
      由 Gerd Hoffmann 提交于 
      This patch adds infrastructure and command line option for setting
global defaults for device properties, i.e. you can for example use

  -global virtio-blk-pci.vectors=0

to turn off msi by default for all virtio block devices.  The config
file syntax is:

[global]
  driver = "virtio-blk-pci"
  property = "vectors"
  value = "0"

This can also be used to set properties for devices which are not
created via -device but implicitly via machine init, i.e.

  -global isa-fdc,driveA=<name>

This patch uses the mechanism which configures properties for the
compatibility machine types (pc-0.10 & friends).  The command line
takes precedence over the machine type values.
