kvm: Query KVM for available memory slots
KVM reports the number of available memory slots (KVM_CAP_NR_MEMSLOTS)
using the extension interface. Both x86 and s390 implement this, ARM
and powerpc do not yet enable it. Convert the static slots array to
be dynamically allocated, supporting more slots when available.
Default to 32 when KVM_CAP_NR_MEMSLOTS is not implemented. The
motivation for this change is to support more assigned devices, where
memory mapped PCI MMIO BARs typically take one slot each.

add firmware to machine options
This patch adds firmware to the machine options. -bios <file> becomes a
shortcut for -machine firmware=<file>. Advantage is that the firmware
can be specified via config file as -machine is parsed using QemuOpts
and it is also possible to use different defaults for different
machine types (via QEMUMachine->default_machine_opts).

block: make bdrv_co_do_write_zeroes stricter in producing aligned requests
Right now, bdrv_co_do_write_zeroes will only try to align the
beginning of the request. However, it is simpler for many
formats to expect the block layer to separate both the head *and*
the tail. This makes sure that the format's bdrv_co_write_zeroes
function will be called with aligned sector_num and nb_sectors for
the bulk of the request.

qemu-io> read -v 0 512
00000000: cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc ................
...
# ./qemu-io --cache=none /dev/sdXX

qemu-io> write -z 0 1M
qemu-io> read -P 0x00 0 512

And similarly with discard instead of "write -z".

scsi-disk: correctly implement WRITE SAME
Fetch the data to be written from the input buffer. If it is all zeroes,
we can use the write_zeroes call (possibly with the new MAY_UNMAP flag).
Otherwise, do as many write cycles as needed, writing 512k at a time.
Strictly speaking, this is still incorrect because a zero cluster should
only be written if the MAY_UNMAP flag is set. But this is a bug in qcow2
and the other formats, not in the SCSI code.

block: Close backing file early in bdrv_img_create
Leaving the backing file open although it is not needed anymore can
cause problems if it is opened through a block driver which allows
exclusive access only and if the create function of the block driver
used for the top image (the one being created) tries to close and reopen
the image file (which will include opening the backing file a second
time).
In particular, this will happen with a backing file opened through
qemu-nbd and using qcow2 as the top image file format (which reopens the
image to flush it to disk).
In addition, the BlockDriverState in bdrv_img_create() is used for the
backing file only; it should therefore be made local to the respective
block.

qcow2: Zero-initialise first cluster for new images
Strictly speaking, this is only required for has_zero_init() == false,
but it's easy enough to just do a cluster-aligned write that is padded
with zeros after the header.
This fixes that after 'qemu-img create' header extensions are attempted
to be parsed that are really just random leftover data.

qemu-iotests: Add "-c <cache-mode>" option
The option sets cache mode used in the tests. "-nocache" is changed to
an alias to "-c none", and internally passes "-t none" to qemu-io.
Python scripts will make use of option this in the next commit.

qemu-img: add support for skipping zeroes in input during convert
we currently do not check if a sector is allocated during convert.
This means if a sector is unallocated that we allocate a bounce
buffer of zeroes, find out its zero later and do not write it
in the best case. In the worst case this can lead to reading
blocks from a raw device (like iSCSI) altough we could easily
know via get_block_status that they are zero and simply skip them.
This patch also fixes the progress output not being at 100% after
a successful conversion.

roms: build two seabios binaries
Adding xhci support to seabios made it jump over the 128k line.
Changing the bios size breaks migration, so we have to keep a
128k seabios binary for old machine types. New machine types can
use a large 256k bios which should be big enougth for a while.
This patch updates the seabios build process to build seabios twice,
once full featured and once with xen and xhci turned off so the
resulting binary is small enougth to fit into 128k.

block: clean up bdrv_drain_all() throttling comments
Since cc0681c45430a1f1a4c2d06e9499b7775afc9a18 ("block: Enable the new
throttling code in the block layer.") bdrv_drain_all() no longer spins.
The code used to look as follows:
do {
busy = qemu_aio_wait();
/* FIXME: We do not have timer support here, so this is effectively
* a busy wait.
*/
QTAILQ_FOREACH(bs, &bdrv_states, list) {
while (qemu_co_enter_next(&bs->throttled_reqs)) {
busy = true;
}
}
} while (busy);
Note that throttle requests are kicked but I/O throttling limits are
still in effect. The loop spins until the vm_clock time allows the
request to make progress and complete.
The new throttling code introduced bdrv_start_throttled_reqs(). This
function not only kicks throttled requests but also temporarily disables
throttling so requests can run.
The outdated FIXME comment can be removed. Also drop the busy = true
assignment since we overwrite it immediately afterwards.

aio: make aio_poll(ctx, true) block with no fds
This patch drops a special case where aio_poll(ctx, true) returns false
instead of blocking if no file descriptors are waiting on I/O. Now it
is possible to block in aio_poll() to wait for aio_notify().
This change eliminates busy waiting. bdrv_drain_all() used to rely on
busy waiting to completed throttled I/O requests but this is no longer
required so we can simplify aio_poll().
Note that aio_poll() still returns false when aio_notify() was used. In
other words, stopping a blocking aio_poll() wait is not considered
making progress.
Adjust test-aio /aio/bh/callback-delete/one which assumed aio_poll(ctx,
true) would immediately return false instead of blocking.

qemu-iotests: filter QEMU monitor \r\n
SMTP does not preserve newlines. This is normally not a problem if the
email body uses DOS or UNIX newlines consistently. In 051.out we mix
UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n).
This patch filters the QEMU monitor output so the golden master file
uses UNIX newlines exclusively.
The result is that patches touching 051.out will apply cleanly without
mangling newlines after this commit.

vfio-pci: Fix Nvidia MSI ACK through 0x88000 quirk
When MSI is enabled on Nvidia GeForce cards the driver seems to
acknowledge the interrupt by writing a 0xff byte to the MSI capability
ID register using the PCI config space mirror at offset 0x88000 from
BAR0. Without this, the device will only fire a single interrupt.
VFIO handles the PCI capability ID/next registers as virtual w/o write
support, so any write through config space is currently dropped. Add
a check for this and allow the write through the BAR window. The
registers are read-only anyway.

We were relying on msix_unset_vector_notifiers() to release all the
vectors when we disable MSI-X, but this only happens when MSI-X is
still enabled on the device. Perform further cleanup by releasing
any remaining vectors listed as in-use after this call. This caused
a leak of IRQ routes on hotplug depending on how the guest OS prepared
the device for removal.

- Additional Nvidia x-vga quirk to ACK MSI interrupts
- Debug options to disable MSI/X KVM acceleration
- Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks
The KVM-VFIO device support enables KVM to manage how it handles
coherency instructions in the presence of non-coherent I/O. Dave
Airlie had noted that the Nvidia MSI ACK support here may just be
scratching the surface, but it's better than what we have now and
it's only enabled via the x-vga option, so I'm willing to add since
it does enable some users.
