target-ppc: IBM PowerPC 440EP Bamboo reference board emulation

Since most IO devices are integrated into the 440EP chip, "Bamboo support"
mostly entails implementing the -kernel, -initrd, and -append options.

These options are implemented by loading the guest as if u-boot had done it,
i.e. loading a flat device tree, updating it to hold initrd addresses, ram
size, and command line, and passing the FDT address in r3.

Since we use it with KVM, we enable the virtio block driver and include hooks
necessary for KVM support.

emulation is supported, the kvm_enabled() hack can be removed.

Implement device tree support needed for Bamboo emulation

To implement the -kernel, -initrd, and -append options, 4xx board emulation
must load the guest kernel as if firmware had loaded it. Where u-boot would be
the firmware, we must load the flat device tree into memory and set key fields
such as /chosen/bootargs.

This patch introduces a dependency on libfdt for flat device tree support.

target-ppc: create a helper function to allow more flexible RAM allocation for PPC 4xx

The 4xx SDRAM controller supports a small number of banks, and each bank must
be one of a small set of sizes. The number of banks and the supported sizes
varies by SoC.

This function uses the user-specified RAM size to fill in the "ram_bases" and
"ram_sizes" arrays required by ppc4xx_sdram_init().

target-i386: SVM: acknowledge interrupt only after it is taken

SVM specifies that the V_IRQ mask is only to be removed, if the
interrupt that is to be delivered actually is delivered.

As of the SVM rewrite, this mask is always unmasked when the main cpu
loop is processed, leaving a corner case where calling the interrupt
handler causes a #PF. In that case (booting Linux / starting gfxboot)
the current implementation tells the VMM the interrupt is taken, even
though it is not.

This patch modifies the VIRQ unmasking to occur after do_interrupt,
making gfxboot work again.

Replace posix-aio with custom thread pool

glibc implements posix-aio as a thread pool and imposes a number of limitations.

1) it limits one request per-file descriptor. we hack around this by dup()'ing
file descriptors which is hideously ugly

2) it's impossible to add new interfaces and we need a vectored read/write
operation to properly support a zero-copy API.

What has been suggested to me by glibc folks, is to implement whatever new
interfaces we want and then it can eventually be proposed for standardization.
This requires that we implement our own posix-aio implementation though.

This patch implements posix-aio using pthreads. It immediately eliminates the
need for fd pooling.

It performs at least as well as the current posix-aio code (in some
circumstances, even better).

pci: add default pci subsystem id for all devices (Gerd Hoffman)

This sets a default PCI subsystem ID for all emulated PCI devices.  PCI
specs require this, so do it.

In many cases it is enougth to know the PCI ID to handle a device
correctly.  Sometimes a device driver must identify the exact piece of
hardware (via PCI Subsystem ID) though.

What does this patch to qemu devices:

Right now the emulated PCI devices have no PCI subsystem ID, only the
PCI ID.  The discussed patch sets a default PCI subsystem ID for all
emulated devices.  Which will make the qemu devices look pretty much
like in the laptop case: all PCI subsystem IDs will point to qemu by
default.

If a driver emulates a very specific piece of hardware where it has to
emulate more than just the PCI chip, it can overwrite the PCI subsystem
ID without problems.  The es1370 driver does that for example.

Fix handling of disk-only snapshots (Kevin Wolf)

When creating a snapshot with multiple qcow2 disks attached, the current
behaviour is that qemu creates a disk snapshot on all of them and
chooses one to write the VM state to.

Despite having the state only in one image, loadvm tries to restore the
VM state from the middle of nowhere if you run qemu a second time with
only one of the other images attached. In the lucky case it will fail
because there simply is no state, but it also can happen that it loads
the state of a different snapshot (the one this new one is based upon).

The fix is to write a zero VM state size to the images which don't
contain the state, and check this in loadvm.

I agree that you probably have to provoke such things intentionally to
get in a state like this with qemu itself. However, with my second patch
that adds snapshot support to qemu-img it could become a reasonable use
case to have snapshots with and without VM states on the same image.

Remove redundant #ifdef _BSD

since _BSD if already handled in osdep.c:qemu_memalign(), we don't need to
check it in the calling function again. getpagesize() is available in BSD.

Don't require linux/auxvec.h, which isn't always installed with libc.

I'm cross-compiling, and linux/auxvec.h was not installed with my glibc
headers. How about this:

Allow to register a callback with fw_cfg_add_callback()
fw_cfg_add_callback() checks if key has FW_CFG_WRITE_CHANNEL bit set
after masking the key with FW_CFG_ENTRY_MASK.

But as FW_CFG_ENTRY_MASK is ~(FW_CFG_WRITE_CHANNEL | FW_CFG_ARCH_LOCAL),
the bit is never set and function exits.

This patch corrects this by checking the bit before masking the value.
