This allows you to specify:

  $ qemu -device virtio-rng-pci

And things will Just Work with a reasonable default.
Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This adds parameters to virtio-rng-pci to allow rate limiting the entropy a
guest receives.  An example command line:

$ qemu -device virtio-rng-pci,max-bytes=1024,period=1000

Would limit entropy collection to 1Kb/s.
Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

The Linux kernel already has a virtio-rng driver, this is the device
implementation.

When the guest asks for entropy from the virtio hwrng, it puts a buffer
in the vq.  We then put entropy into that buffer, and push it back to
the guest.

aliguori: converted to new RngBackend interface
aliguori: remove entropy needed event
aliguori: fix migration

This backend talks EGD to a CharDriverState.  A typical way to invoke this would
be:

qemu -chardev socket,host=localhost,port=1024,id=chr0 \
     -object rng-egd,chardev=chr0,id=egd0 \
     -device virtio-rng-pci,rng=egd0
Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

The filename can be overridden but it expects a non-blocking source of entropy.
A typical invocation would be:

qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0

This can also be used with /dev/urandom by using the command line:

qemu -object rng-random,filename=/dev/urandom,id=rng0 \
     -device virtio-rng-pci,rng=rng0

This will create a new QOM object in the '/objects' path.  Note that properties
are set in order which allows for simple objects to be initialized entirely
with this option and then realized.

This option is roughly equivalent to -device but for things that are not

According to the MIPS Malta Developement Platform User's Manual, the
i8259 interrupt controller is supposed to be connected to the hardware
IRQ0, and the CBUS UART to the hardware interrupt 2.

In QEMU they are both connected to hardware interrupt 0, the CBUS UART
interrupt being wrong. This patch fixes that. It should be noted that
the irq array in QEMU includes the software interrupts, hence
env->irq[2] is the first hardware interrupt.

This makes use of the new level irqfd support enabling bypass of qemu
userspace both on INTx injection and unmask.  This significantly
boosts the performance of devices making use of legacy interrupts (ex.
~60% better netperf TCP_RR scores for an e1000e assigned to a Linux
guest and booted with pci=nomsi).  This also avoids flipping mmaps on
and off to simulate EOIs, so greatly improves performance of device
access in addition to interrupt latency.

Commit ed2aec4867f0d5f5de496bb765347b5d0cfe113d changed the return
value of aio_ctx_prepare from false to true when only idle bottom
halves are available.  This broke PC old-style DMA, which uses them.
Fix this by making aio_ctx_prepare return true only when non-idle
bottom halves are scheduled to run.

Define a new global dma_context_memory which is a DMAContext corresponding
to the global address_space_memory AddressSpace. This can be used by
sysbus peripherals like sysbus-ohci which need to do DMA.

In particular, use it in the sysbus-ohci device, which fixes a
segfault when attempting to use that device.
