      kvm: Add a new machine option kvm-type · 135a129a
      由 Aneesh Kumar K.V 提交于 
      Targets like ppc64 support different types of KVM, one which use
hypervisor mode and the other which doesn't. Add a new machine
option kvm-type that helps in selecting the respective ones
We also add a new QEMUMachine callback get_vm_type that helps
in mapping the string representation of kvm type specified.

      KVM: Split QEMUMachine typedef into separate header · 9c06a1f7
      由 Alexander Graf 提交于 
      Older gcc versions (such as the one in SLES11) get confused when you declare
a typedef on the same struct twice.

To work around that limitation, let's extract the QEMUMachine typedef into a
separate header file that is guarded by preprocessor duplicate include checks.

This fixes the following type of compile errors for me:

  In file included from vl.c:125:
  include/hw/xen/xen.h:39: error: redefinition of typedef "QEMUMachine"
  include/sysemu/kvm.h:155: error: previous declaration of "QEMUMachine" was here

      hw: Clean up bogus default boot order · c1654732
      由 Markus Armbruster 提交于 
      We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.

Machines that care:

* pc and its variants

  Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
  'c', 'd' and 'n'.  Reject all others (fatal with -boot).

* nseries (n800, n810)

  Check whether order starts with 'n'.  Silently ignored otherwise.

* prep, g3beige, mac99

  Extract the first character the machine understands (subset of
  'a'..'f').  Silently ignored otherwise.

* spapr

  Accept an arbitrary string (vl.c restricts it to contain only
  'a'..'p', no duplicates).

* sun4[mdc]

  Use the first character.  Silently ignored otherwise.

Strip characters these machines ignore from their default boot order.

For all other machines, remove the unused default boot order
alltogether.

Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.

      hw: move headers to include/ · 0d09e41a
      由 Paolo Bonzini 提交于 
      Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

      hw: include hw header files with full paths · 83c9f4ca
      由 Paolo Bonzini 提交于 
      Done with this script:

cd hw
for i in `find . -name '*.h' | sed 's/^..//'`; do
  echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`

This is so that paths remain valid as files are moved.

Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

      Support default block interfaces per QEMUMachine · 2d0d2837
      由 Christian Borntraeger 提交于 
      There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.

This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)

To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.

I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.

      create struct for machine initialization arguments · 5f072e1f
      由 Eduardo Habkost 提交于 
      This should help us to:
- More easily add or remove machine initialization arguments without
  having to change every single machine init function;
- More easily make mechanical changes involving the machine init
  functions in the future;
- Let machine initialization forward the init arguments to other
  functions more easily.

This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

      Allow QEMUMachine to override reset sequencing · be522029
      由 David Gibson 提交于 
      qemu_system_reset() function always performs the same basic actions on
all machines.  This includes running all the reset handler hooks,
however the order in which these will run is not always easily predictable.

This patch splits the core of qemu_system_reset() - the invocation of
the reset handlers - out into a new qemu_devices_reset() function.
qemu_system_reset() will usually call qemu_devices_reset(), but that
can be now overriden by a new reset method in the QEMUMachine
structure.

Individual machines can use this reset method, if necessary, to
perform any extra, machine specific initializations which have to
occur before or after the bulk of the reset handlers.  It's expected
that the method will call qemu_devices_reset() at some point, but if
the machine has really strange ordering requirements between devices
resets it could even override that with it's own reset sequence (with
great care, obviously).

For a specific example of when this might be needed: a number of
machines (but not PC) load images specified with -kernel or -initrd
directly into the machine RAM before booting the guest.  This mostly
works at the moment, but to make this actually safe requires that this
load occurs after peripheral devices are reset - otherwise they could
have active DMAs in progress which would clobber the in memory images.
Some machines (notably pseries) also have other entry conditions which
need to be set up as the last thing before executing in guest space -
some of this could be considered "emulated firmware" in the sense that
the actions of the firmware are emulated directly by qemu rather than
by executing a firmware image within the guest.  When the platform's
firmware to OS interface is sufficiently well specified, this saves
time both in implementing the "firmware" and executing it.

      Add machine type aliases · 3f6599e6
      由 Mark McLoughlin 提交于 
      Add an 'alias' field to QEMUMachine and display it in the output of
'qemu -M ?' with an '(aliased to foo)' suffix.

Aliases can change targets in newer versions of qemu, so management tools
may choose canonicalize machine types to ensure that if a user chooses an
alias, that the actual machine type used will remain compatible in
future.

This is intended to mimic a symlink to a machine description file.
