Microport UNIX System V/386 v 2.1 (ca 1987) tries to program

with proper handling of EGA/VGA-only registers. Note that it didn't
work on real VGA hardware, either (although in that case, the most

pci_host: Turn into SysBus-derived QOM type
The preceding commits fixed misuses of FROM_SYSBUS() that led people to
add a bogus busdev field. For qdev the field order was less relevant but
for QOM the PCIHostState field (including the SysBusDevice actually
initialized with a value) must be placed first within the state struct.
To facilitate accessing the PCIHostState fields, derive all PCI host
bridges from TYPE_PCI_HOST_BRIDGE rather than TYPE_SYS_BUS_DEVICE.
We can now access PCIHostState QOM-style, with PCI_HOST_BRIDGE() macro.

The cached mapped entry is saved in last_address_vaddr with the memory

eventfd: making it thread safe
QEMU uses IO handlers to run select() in the main loop.
The handlers list is managed by qemu_set_fd_handler() helper
which works fine when called from the main thread as it is
called when select() is not waiting.
However IO handlers list can be changed in the thread other than
the main one doing os_host_main_loop_wait(), for example, as a result
of a hypercall which changes PCI config space (VFIO on POWER is the case)
and enables/disabled MSI/MSIX which closes/creates eventfd handles.
As the main loop should be waiting on the newly created eventfds,
it has to be restarted.
The patch adds the qemu_notify_event() call to interrupt select()
to make main_loop() restart select() with the updated IO handlers
list.

virtio-blk: support VIRTIO_BLK_F_CONFIG_WCE
Also rename VIRTIO_BLK_F_WCACHE to VIRTIO_BLK_F_WCE for consistency with
the spec.

Documentation: Warn against qemu-img on active image
People have repeatedly expected that you can do things like snapshotting
an image with qemu-img while a qemu instance is running. Maybe we need
to consider locking the files while they are in use, but having a
warning in the qemu-img manpage is doable for 1.2 and can't hurt anyway.

vmdk: Read footer for streamOptimized images
The footer takes precedence over the header when it exists. It contains

qemu-char: (Re-)connect for tcp_chr_write() unconnected writing
tcp_chr_write() did not deal with writing to an unconnected
connection and return the original length of the data, it's
not right and would cause false writing. So (re-)connect it
and return 0 for this situation.

Allow QEMUMachine to override reset sequencing
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.

pseries: Instantiate USB interface when required
The pseries machine already supports the -vga std option, creating a
graphics adapter. However, this is not very useful without being able to
add a keyboard and mouse as well. This patch addresses this by adding
a USB interface when requested, and automatically adding a USB keyboard
and mouse when VGA is enabled.
This is a stop gap measure to get usable graphics mode on pseries while
waiting for Li Zhang's rework of USB options to go in after 1.2.
