093bc2cd88 Hierarchical memory region API
The memory API separates the attributes of a memory region (its size, how
reads or writes are handled, dirty logging, and coalescing) from where it
is mapped and whether it is enabled.  This allows a device to configure
a memory region once, then hand it off to its parent bus to map it according
to the bus configuration.

Hierarchical registration also allows a device to compose a region out of
a number of sub-regions with different properties; for example some may be
RAM while others may be MMIO.

679f4f8b17 xen: implement unplug protocol in xen_platform
The unplug protocol is necessary to support PV drivers in the guest: the
drivers expect to be able to "unplug" emulated disks and nics before
initializing the Xen PV interfaces.
It is responsibility of the guest to make sure that the unplug is done
before the emulated devices or the PV interface start to be used.

We use pci_for_each_device to walk the PCI bus, identify the devices and
disks that we want to disable and dynamically unplug them.

Changes in v2:

- use PCI_CLASS constants;

- replace pci_unplug_device with qdev_unplug;

- do not import hw/ide/internal.h in xen_platform.c;

Changes in v3:

- introduce piix3-ide-xen, that support hot-unplug;

- move the unplug code to hw/ide/piix.c;

- just call qdev_unplug from xen_platform.c to unplug the IDE disks;

8a369e20e7 xen: Fix the memory registration to reflect of what is done by Xen.
A Xen guest memory is allocated by libxc. But this memory is not
allocated continuously, instead, it leaves the VGA IO memory space not
allocated, same for the MMIO space (at HVM_BELOW_4G_MMIO_START of size
HVM_BELOW_4G_MMIO_LENGTH).

So to reflect that, we do not register the physical memory for this two
holes. But we still keep only one RAMBlock for the all RAM as it is more
easier than have two separate blocks (1 above 4G). Also this prevent QEMU
from use the MMIO space for a ROM.

59d21e537b xen: make xen_enabled even more clever
When using xen_enabled() we're currently only checking if xen is enabled
at all during the build. But what if you want to build multiple targets
out of which only one can potentially run xen code?

That means that for generic code we'll still have to fall back to the
variable and potentially slow the code down, but it's not as important as
that is mostly xen device emulation which is not touched for non-xen targets.

The target specific code however can with this patch see that it's unable to
ever execute xen code. We can thus always return 0 on xen_enabled(), giving
gcc enough hints to evict the mapcache code from the target memory management
code.

d25f89c9e9 Register Linux dyntick timer as per-thread signal
Derived from kvm-tool patch
http://thread.gmane.org/gmane.comp.emulators.kvm.devel/74309

Ingo Molnar pointed out that sending the timer signal to the whole
process, just blocking it everywhere, is suboptimal with an increasing
number of threads. QEMU is also using this pattern so far.

Linux provides a (non-portable) way to restrict the signal to a single
thread: We can use SIGEV_THREAD_ID unless we are forced to emulate
signalfd via an additional thread. That case could theoretically be
optimized as well, but it doesn't look worth bothering.

691a0c9c9b qemu-timer: Introduce clock reset notifier
QEMU_CLOCK_HOST is based on the system time which may jump backward in
case the admin or NTP adjusts it. RTC emulations and other device models
can suffer in this case as timers will stall for the period the clock
was tuned back.

This adds a detection mechanism that checks on every host clock readout
if the new time is before the last result. If that is the case a
notifier list is informed. Device models interested in this event can
register a notifier with the clock.

021a131860 virtio-serial: Clean up virtser_bus_dev_print() output
Old version looks like this in info qtree (last four lines):

          dev: virtconsole, id ""
            dev-prop: is_console = 1
            dev-prop: nr = 0
            dev-prop: chardev = <null>
            dev-prop: name = <null>
             dev-prop-int: id: 0
             dev-prop-int: guest_connected: 1
             dev-prop-int: host_connected: 0
             dev-prop-int: throttled: 0

Indentation is off, and "dev-prop-int" suggests these are properties
you can configure with -device, which isn't the case.  The other
buses' print_dev() callbacks don't do that.  For instance, PCI's
output looks like this:

        class Ethernet controller, addr 00:03.0, pci id 1af4:1000 (sub 1af4:0001)
        bar 0: i/o at 0xffffffffffffffff [0x1e]
        bar 1: mem at 0xffffffffffffffff [0xffe]
        bar 6: mem at 0xffffffffffffffff [0xfffe]

Change virtser_bus_dev_print() to that style.  Result:

          dev: virtconsole, id ""
            dev-prop: is_console = 1
            dev-prop: nr = 0
            dev-prop: chardev = <null>

1366108981 Introduce a 'client_add' monitor command accepting an open FD
Allow client connections for VNC and socket based character
devices to be passed in over the monitor using SCM_RIGHTS.

One intended usage scenario is to start QEMU with VNC on a
UNIX domain socket. An unprivileged user which cannot access
the UNIX domain socket, can then connect to QEMU's VNC server
by passing an open FD to libvirt, which passes it onto QEMU.

 { "execute": "get_fd", "arguments": { "fdname": "myclient" } }
 { "return": {} }
 { "execute": "add_client", "arguments": { "protocol": "vnc",
                                           "fdname": "myclient",
                                           "skipauth": true } }
 { "return": {} }

In this case 'protocol' can be 'vnc' or 'spice', or the name
of a character device (eg from -chardev id=XXXX)

The 'skipauth' parameter can be used to skip any configured
VNC authentication scheme, which is useful if the mgmt layer
talking to the monitor has already authenticated the client
in another way.

* console.h: Define 'vnc_display_add_client' method
* monitor.c: Implement 'client_add' command

3. wait for shutdown event
4. reset the vm by monitor command system_reset

no_shutdown will be reset to 0 if the vm is powered down.
We only can reboot the vm once.

6141dbfe0a report serial devices created with -device in the PIIX4 config space
Serial and parallel devices created with -device are not reported in
the PIIX4 configuration space, and are hence not picked up by the DSDT.
This upsets Windows, which hides them altogether from the guest.

To avoid this, check at the end of machine initialization whether the
corresponding I/O ports have been registered.  The new function in
ioport.c does this; this also requires a tweak to isa_unassign_ioport.

I left the comment in piix4_pm_initfn since the registers I moved do
seem to match the 82371AB datasheet.  There are some quirks though.
We are setting this bit:

    "Device 8 EIO Enable (EIO_EN_DEV8)—R/W. 1=Enable PCI access to the
    device 8 enabled I/O ranges to be claimed by PIIX4 and forwarded
    to the ISA/EIO bus. 0=Disable. The LPT_MON_EN must be set to enable
    the decode."

but not LPT_MON_EN (bit 18 at 50h):

    LPT Port Enable (LPT_MON_EN)—R/W. 1=Enable accesses to parallel
    port address range (LPT_DEC_SEL) to generate a device 8 (parallel
    port) decode event. 0=Disable.

We're also setting the LPT_DEC_SEL field (that's the 0x60 written to
63h) to 11, which means reserved, rather than to 01 (378h-37Fh).

Likewise we're not setting SA_MON_EN, SB_MON_EN (respectively bit 14
and bit 16 at address 50h) for the serial ports.  However, we're setting
COMA_DEC_SEL and COMB_DEC_SEL correctly, unlike the corresponding register
for the parallel port.

All these fields are left as they are, since they are probably only
meant to be used in the DSDT.

6eed18568d net: Consistently use qemu_macaddr_default_if_unset
Drop the open-coded MAC assignment from net_init_nic and replace it with
standard qemu_macaddr_default_if_unset which is also used by qdev. That
avoid creating colliding MACs when instantiating NICs via different
mechanisms.

This change requires to store the MAC as MACAddr in NICInfo, and the
remaining nd_table users need to be updated.

Based on suggestion by Peter Maydell.
