Since commit 1dc936aa84 (virtio-blk: Use blk_aio_ioctl) we silently lose
the request if blk_aio_ioctl returns NULL (not implemented).
Fix it by directly returning VIRTIO_BLK_S_UNSUPP as we used to do.

When do memory balloon, it takes the 'ram_size' as the VM's current ram size,
But 'ram_size' is the startup configured ram size, it does not take into
account the hotplugged memory.
As a result, the balloon result will be confused.
Steps to reproduce:
(1)Start VM: qemu -m size=1024,slots=4,maxmem=8G
(2)In VM: #free -m : 1024M
(3)qmp balloon 512M
(4)In VM: #free -m : 512M
(5)hotplug pc-dimm 1G
(6)In VM: #free -m : 1512M
(7)qmp balloon 256M
(8)In VM: #free -m :1256M
We expect the VM's available ram size to be 256M after 'qmp balloon 256M'
command, but VM's real available ram size is 1256M.
For "qmp balloon" is not performance critical code, we use function
'get_current_ram_size' to get VM's current ram size.

The global parameter 'ram_size' does not take into account
the hotplugged memory.
In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.
Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory devices and also plus ram_size.

ASSERT (TrsRing != NULL) [4]
UsbEnumerateNewDev() in the USB bus driver issues a GET_DESCRIPTOR
request, in order to determine the number of configurations that the
endpoint supports. The requests consists of three stages (three TRBs),
setup, data, and status. The length of the response is determined in [1],
namely from the transfer event that the host controller generates in
response to the request's middle stage (ie. the data stage).
If the length of the answer is correct (a full GET_DESCRIPTOR request
takes 18 bytes), then the XHCI driver that underlies the USB bus driver
"snoops" (caches) the descriptor data for later [2].
Later, the USB bus driver sends a SET_CONFIG request. The underlying XHCI
driver allocates a transfer ring for the endpoint, relying on the data
snooped and cached in step [2].
Finally, the USB keyboard driver submits an asynchronous interrupt
transfer to manage the keyboard. As part of this it asserts [4] that the
ring has been allocated in step [3].
And this ASSERT() fires. The root cause can be found in the way QEMU
handles the initial GET_DESCRIPTOR request.
Again, that request consists of three stages (TRBs, Transfer Request
Blocks), "setup", "data", and "status". The XhcCreateTransferTrb()
function sets the IOC ("Interrupt on Completion") flag in each of these
TRBs.
According to the XHCI specification, the host controller shall generate a
Transfer Event in response to *each* individual TRB of the request that
had the IOC flag set. This means that QEMU should queue three events:
setup, data, and status, for edk2's XHCI driver.
However, QEMU only generates two events:
- one for the setup (ie. 1st) stage,
- another for the status (ie. 3rd) stage.
No event is generated for the middle (ie. data) stage. The loop in QEMU's
xhci_xfer_report() function runs three times, but due to the "reported"
variable, only the first and the last TRBs elicit events, the middle (data
stage) results in no event queued.
As a consequence:
- When handling the GET_DESCRIPTOR request, XhcCheckUrbResult() in [1]
does not update the response length from zero.
- XhcControlTransfer() thinks that the response is invalid (it has zero
length payload instead of 18 bytes), hence [2] is not reached; the
device descriptor is not stashed for later, and the number of possible
configurations is left at zero.
- When handling the SET_CONFIG request, (NumConfigurations == 0) from
above prevents the allocation of the endpoint's transfer ring.
- When the keyboard driver tries to use the endpoint, the ASSERT() blows
up.
The solution is to correct the emulation in QEMU, and to generate a
transfer event whenever IOC is set in a TRB.
The patch replaces
!reported && (IOC || foo) == !reported && IOC ||
!reported && foo
with
IOC || (!reported && foo) == IOC ||
!reported && foo
which only changes how
reported && IOC
is handled. (Namely, it now generates an event.)
Tested with edk2 built for "qemu-system-aarch64 -M virt" (ie.

vga_common_init() doesn't allow more than 256 MiB vram size and silently
shrinks any larger value. qxl_dirty_surfaces() used the unshrinked size
via qxl->shadow_rom.surface0_area_size when accessing the memory, which
resulted in segfault.
Add a workaround for this case and an assert if it happens again.
We have to bump the vga memory limit too, because 256 MiB wouldn't have
allowed 8k (it requires more than 128 MiB).
1024 MiB doesn't work, but 512 MiB seems fine.

Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow
the kernel to request a device from the user. When signaled, QEMU
will by default attmempt to hot-unplug the device. This is a one-
shot attempt with the expectation that the kernel will continue to
poll for the device if it is not returned. Returning the device when
requested is the expected standard model of cooperative usage, but we
also add an option option to disable this feature. Initially this
opt-out is set as an experimental option because we really should
honor kernel requests for the device.

s->blocker is really only used in hw/scsi/virtio-scsi.c; the only places
where it is used in hw/scsi/virtio-scsi-dataplane.c is when it is
allocated and when it is freed. That does not make a whole lot of sense
(and is actually wrong because this leads to s->blocker potentially
being NULL when blk_op_block_all() is called in virtio-scsi.c), so move
the allocation and destruction of s->blocker to the device realization

Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic
creation of sysbus devices. However, at present it is used only for the
PPC E500 target, with plans for the ARM "virt" target in the immediate
future.
To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

The i82801b11, ioh3420 and xio3130 PCI Express devices are currently
included in the build unconditionally.
While they could theoretically appear on any target platform with PCI-E,
they're pretty unlikely to appear on platforms that aren't Intel derived.
Therefore, to avoid presenting unlikely-to-be-relevant devices to the user,
add config options to enable these components, and enable them by default
only on x86 and arm platforms.
(Note that this patch does include these for aarch64, via its inclusion of
arm-softmmu.mak).

It's not safe to call blk_set_aio_context from outside BQL because of
the bdrv_drain_all there. Let's put it in the hotplug callback which
will be called by qdev device realization for each scsi device attached
to the bus.

This mimics what is done in qdev_device_add, and lets the device be
freed in case something goes wrong. Otherwise, object_unparent returns
immediately without freeing the device, which is on the other hand left
in the parent bus's list of children.
scsi_bus_legacy_handle_cmdline then returns an error, and the HBA is
destroyed as well with object_unparent. But the lingering device that
was not removed in scsi_bus_legacy_add_drive cannot be removed now either,
and bus_unparent gets stuck in an infinite loop trying to empty the list
of children.
The right fix of course would be to assert in bus_add_child that the
device already has a bus, and remove the "safety net" that adds the
drive to the QOM tree in device_set_realized. I am not yet sure whether
that would entail changing all callers to qdev_create (as well as
isa_create and usb_create and the corresponding _try_create versions).

qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().
Most of its users assume the function can't fail. Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.
Just two users remain, in util/qemu-config.c. Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().
