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.

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.)

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.

Either 'once' option or 'order' option can take effect for -boot at
the same time, that is say initial startup processing can check only
one. And pc.c's set_boot_dev() fails when its boot order argument
is invalid. This patch provide a solution fix this problem:
1. If "once" is given, register reset handler to restore boot order.
2. Pass the normal boot order to machine creation. Should fail when
the normal boot order is invalid.
3. If "once" is given, set it with qemu_boot_set(). Fails when the
once boot order is invalid.
4. Start the machine.
5. On reset, the reset handler calls qemu_boot_set() to restore boot
order. Should never fail.

Add helpers helper_addsur_h/_ssov which adds one halfword and subtracts one
halfword, rounds / and saturates each half word independently.
Add microcode helper functions:
* gen_maddsu_h/sus_h: multiply two halfwords left justified and add to the
first one word and subtract from the second one word
/ and saturate each resulting word independetly.
* gen_maddsum_h/sums_h: multiply two halfwords in q-format left justified
and add to the first one word and subtract from
the second one word / and saturate each resulting
word independetly.
* gen_maddsur32_h/32s_h: multiply two halfwords in q-format left justified
and add to the first one word and subtract from
the second one word, round both results / and
saturate each resulting word independetly.

Add helpers:
* madd64_q_ssov: multiply two 32 bit q-format number, add them with a
64 bit q-format number and saturate.
* madd32_q_add_ssov: add two 64 bit q-format numbers and return a 32 bit
result.
* maddr_q_ssov: multiplay two 32 bit q-format numbers, add a 32 bit
q-format number and saturate.
* maddr_q: multiplay two 32 bit q-format numbers and add a 32 bit
q-format number.
Note: madd instructions in the q format can behave strange, e.g.
0x1 + (0x80000000 * 0x80000000) << 1 for 32 bit signed values does not cause an
overflow on the guest, because all intermediate results should be handled as if
they are indefinitely precise. We handle this by inverting the overflow bit for
all cases: a + (0x80000000 * 0x80000000) << 1.

If the signed result of the multiplication overflows, we would get a negative
value, which would result in a addition instead of a subtraction.
Now we do the overflow calculation and saturation by hand instead of using
suov32_neg.

It looks like the dtrace trace code gets upset if you have trace names
with __ in, which the migration/rdma.c code does.
Rename the functions and the associated traces.

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.

Disabling MMAP support uses the slower read/write accesses but allows to
trace all MMIO accesses, which is not good for performance, but very
useful for reverse engineering PCI drivers. This option allows to
disable MMAP per device without a compile-time change.
