57a46d0579 Convert linux bootrom to external rom and fw_cfg
We already have a working multiboot implementation that uses fw_cfg to get
its kernel module etc. data in int19 runtime now.

So what's missing is a working linux boot option rom. While at it I figured it
would be a good idea to take the opcode generator out of pc.c and instead use
a proper option rom, like we do with multiboot.

So here it is - an fw_cfg using option rom for -kernel with linux!

77873196f3 Convert multiboot to fw_cfg backed data storage
Right now we load the guest kernel to RAM, fire off the BIOS, hope it
doesn't clobber memory and run an option rom that jumps into the kernel.

That breaks with SeaBIOS, as that clears memory. So let's read all
kernel, module etc. data using the fw_cfg interface when in the int19
handler.

This patch implements said mechanism for multiboot.

c163b5cae9 Block live migration
This patch introduces block migration called during live migration. Block
are being copied to the destination in an async way. First the code will
transfer the whole disk and then transfer all dirty blocks accumulted during
the migration.
Still need to improve transition from the iterative phase of migration to the
end phase. For now transition will take place when all blocks transfered once,
all the dirty blocks will be transfered during the end phase (guest is
suspended).

Changes from v4:
- Global variabels moved to a global state structure allocated dynamically.
- Minor coding style issues.
- Poll block.c for tracking of dirty blocks instead of manage it here.

bridge were using the same devfn, 11 << 3. The net effect was that only
AGP bridge was visible. This was changed in the commit to 13 << 3 for AGP.

Some of the later crashes happened due to NULL pointer dereferences generated
by 07b7d05377 and insufficient return value
checks.

So a fixed baudbase which is only set once can be wrong.

  because header type 01 doesn't have subsystem id, and uses the register
  for other purpose. So setting default subsystem id doesn't make sense.

- initialize wmask more for header type 01.(bridge header type)
  Without those wmasks, linux was confused not boot,
  and lspci was confused not to print out expected IO/memory range.

pci_update_mapping() path isn't performance critical,

e822a52a81 pci: make pci configuration transaction more accurate.
This patch sorts out/enhances pci code to track pci bus topology
more accurately.
- Track host bus bridge with pci domain number. Although the
  current qemu implementation supports only pci domian 0 yet.
- Track pci bridge parent-child relationship.
When looking down from pci host bus for pci sub bus, be aware of
secondary bus/subordinate bus.
Thus pci configuration transaction is more accurately emulated.

This patch adds new member to PCIBus to track pci bus topology.
Since qdev already tracks down bus relationship, those new member
wouldn't be necessary.
However it would be addressed later because not all the pci device
isn't converted to qdev yet.

Later a structures declared in pci_host.h, PCIHostState, will be used.
However pci_host.h doesn't allow to include itself easily. This patches
addresses it.

pci_host.h includes functions which are instantiated in .c by including
pci_host.h with typedefing pci_addr_t.
pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio
or target_phys_addr_t for mmio in .c file.
That prevents from including pci_host.h to use PCIHostState because of
requiring type, pci_addr_t.

Its purpose to include is to instantiate io function for mmio or ioio
depending on which pci host bridge requires ioio or mmio.
To avoid including code, we always instantiate both version.

184bd04845 whitelist host virtio networking features
This patch is a followup to 8eca6b1bc7,
fixing crashes when guests with 2.6.25 virtio drivers have saturated
virtio network connections.

https://bugs.edge.launchpad.net/ubuntu/+source/qemu-kvm/+bug/458521

That patch should have been whitelisting *_HOST_* rather than the the
*_GUEST_* features.

I tested this by running an Ubuntu 8.04 Hardy guest (2.6.24 kernel +
2.6.25-virtio driver).  I saturated both the incoming, and outgoing
network connection with nc, seeing sustained 6MB/s up and 6MB/s down
bitrates for ~20 minutes.  Previously, this crashed immediately.  Now,
the guest does not crash and maintains network connectivity throughout
the test.

eb852011ab Configurable block format whitelist
We have code for a quite a few block formats.  While I trust that all
of these formats are useful at least for some people in some
circumstances, some of them are of a kind that friends don't let
friends use in production.

This patch provides an optional block format whitelist, default off.
If a whitelist is configured with --block-drv-whitelist, QEMU proper
can use only whitelisted formats.  Other programs, like qemu-img, are
not affected.

Drivers for formats off the whitelist still participate in format
probing, to ensure all programs probe exactly the same.  Without that,
QEMU proper would be prone to treat images with a format off the
whitelist as raw when the image's format is probed.

c169998802 v3: don't call reset functions on cpu initialization
There is absolutely no need to call reset functions when initializing
devices. Since we are already registering them, calling qemu_system_reset()
should suffice. Actually, it is what happens when we reboot the machine,
and using the same process instead of a special case semantics will even
allow us to find bugs easier.

Furthermore, the fact that we initialize things like the cpu quite early,
leads to the need to introduce synchronization stuff like qemu_system_cond.
This patch removes it entirely. All we need to do is call qemu_system_reset()
only when we're already sure the system is up and running

I tested it with qemu (with and without io-thread) and qemu-kvm, and it
seems to be doing okay - although qemu-kvm uses a slightly different patch.

[ v2: user mode still needs cpu_reset, so put it in ifdef. ]
[ v3: leave qemu_system_cond for now. ]

Fixes a couple of issues with msix table access:
- With misbehaving guests, misaligned 4 byte access could overflow
  msix table and cause qemu to segfault. Since PCI spec requires
  host to only issue dword-aligned accesses, as a fix,
  it's enough to mask the address low bits.
- Tables use pci format, not native format, and so
  we must use pci_[sg]et_long on read/write.

Add a auto_attach field to USBDevice, which is enabled by default.
USB drivers can clear this field in case they do *not* want the device
being attached (i.e. plugged into a usb port) automatically after
successfull init().

Use cases (see next patches):
 * attaching encrypted mass storage devices.
 * -usbdevice host:...

0958b4cc8f usb core: use qdev for -usbdevice
This patchs adds infrastructure to handle -usbdevice via qdev callbacks.
USBDeviceInfo gets a name field (for the -usbdevice driver name) and a
callback for -usbdevice parameter parsing.

The new usbdevice_create() function walks the qdev driver list and looks
for a usb driver with a matching name.  When a parameter parsing
callback is present it is called, otherwise the device is created via
usb_create_simple().

de2aff17a3 rom loader: make vga+rom loading configurable.
The rom_add_vga() and rom_add_option() macros are transformed into
functions.  They look at the new rom_enable_driver_roms variable
and only do something if it is set to non-zero, making vga+option rom
loading runtime option.  pc_init() sets rom_enable_driver_roms to 1.

With this in place we can move the rom loading calls from pc.c to the
individual drivers.

Prevent this scenario by adding a flag to virtio-net's savevm format
which indicates whether the device requires host UFO support.

1d41b0c1ec Work around dhclient brokenness
With the latest GSO/csum offload patches, any guest using an unpatched version
of dhclient (any Ubuntu guest, for instance), will no longer be able to get
a DHCP address.

dhclient is actually at fault here.  It uses AF_PACKET to receive DHCP responses
but does not check auxdata to see if the packet has a valid csum.  This causes
it to throw out the DHCP responses it gets from the virtio interface as there
is not a valid checksum.

Fedora has carried a patch to fix their dhclient (it's needed for Xen too) but
this patch has not made it into a release of dhclient.  AFAIK, the patch is in
the dhclient CVS but I cannot confirm since their CVS is not public.

This patch, suggested by Rusty, looks for UDP packets (of a normal MTU) and
explicitly adds a checksum to them if they are missing one.

This allows unpatched dhclients to continue to work without needing to update
the guest kernels.

3a330134b3 virtio-net: add vnet_hdr support
With '-netdev tap,id=foo -nic model=virtio,netdev=foo' virtio-net can
detect that its peer (i.e. the tap backend) supports vnet headers
and advertise to the guest that it can send packets with partial
checksums and/or TSO packets.

One complication is that if we're migrating and the source host
supports IFF_VNET_HDR but the destination host doesn't, we can't then
stop the guest from using those features. In this scenario, we just
fail the migration.

30d335d68d hotplug: more fixes for scsi disk hotplug.
Changes:
 - create common scsi_hot_add function for adding a scsi disk to
   a adapter.
 - Add sanity checks.  You can't drive_add disks to the VGA any more.
 - Ignore the unit value calculated by drive_init, add a comment
   explaining why.  Review the patch to find the details ;)

5b684b5a56 hotplug: fix "pci_add storage if=scsi"
Explicitly add the drive to the bus of the newly created scsi adapter
instead of hoping that scsi_bus_legacy_handle_cmdline() picks it up
correctly.

e8ee28fb3e isa: configure serial+parallel by index.
This patch adds a 'index' property to the isa-parallel and isa-serial
devices.  This can be used to create devices with the default isa irqs
and ioports by simply specifying the index, i.e.

   -device isa-serial,index=1

instead of

   -device isa-serial,iobase=0x2f8,irq=3

for ttyS1 aka com2.  Likewise for parallel ports.
