The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.
So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.

PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions. Add such properties to the ICH9 chipset as well for the Q35
machine type.
S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.
The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.
These can be disabled via the cmdline:
... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1
Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

(1) Let's contemplate what device endianness means, for a memory mapped
device register (independently of QEMU -- that is, on physical hardware).
It determines the byte order that the device will put on the data bus when
the device is producing a *numerical value* for the CPU. This byte order
may differ from the CPU's own byte order, therefore when software wants to
consume the *numerical value*, it may have to swap the byte order first.
For example, suppose we have a device that exposes in a 2-byte register
the number of sheep we have to count before falling asleep. If the value
is decimal 37 (0x0025), then a big endian register will produce [0x00,
0x25], while a little endian register will produce [0x25, 0x00].
If the device register is big endian, but the CPU is little endian, the
numerical value will read as 0x2500 (decimal 9472), which software has to
byte swap before use.
However... if we ask the device about who stole our herd of sheep, and it
answers "XY", then the byte representation coming out of the register must
be [0x58, 0x59], regardless of the device register's endianness for
numeric values. And, software needs to copy these bytes into a string
field regardless of the CPU's own endianness.
(2) QEMU's device register accessor functions work with *numerical values*
exclusively, not strings:
The emulated register's read accessor function returns the numerical value
(eg. 37 decimal, 0x0025) as a *host-encoded* uint64_t. QEMU translates
this value for the guest to the endianness of the emulated device register
(which is recorded in MemoryRegionOps.endianness). Then guest code must
translate the numerical value from device register to guest CPU
endianness, before including it in any computation (see (1)).
(3) However, the data register of the fw_cfg device shall transfer strings
*only* -- that is, opaque blobs. Interpretation of any given blob is
subject to further agreement -- it can be an integer in an independently
determined byte order, or a genuine string, or an array of structs of
integers (in some byte order) and fixed size strings, and so on.
Because register emulation in QEMU is integer-preserving, not
string-preserving (see (2)), we have to jump through a few hoops.
(3a) We defined the memory mapped fw_cfg data register as
DEVICE_BIG_ENDIAN.
The particular choice is not really relevant -- we picked BE only for
consistency with the control register, which *does* transfer integers --
but our choice affects how we must host-encode values from fw_cfg strings.
(3b) Since we want the fw_cfg string "XY" to appear as the [0x58, 0x59]
array on the data register, *and* we picked DEVICE_BIG_ENDIAN, we must
compose the host (== C language) value 0x5859 in the read accessor
function.
(3c) When the guest performs the read access, the immediate uint16_t value
will be 0x5958 (in LE guests) and 0x5859 (in BE guests). However, the
uint16_t value does not matter. The only thing that matters is the byte
pattern [0x58, 0x59], which the guest code must copy into the target
string *without* any byte-swapping.
(4) Now I get to explain where I screwed up. :(
When we decided for big endian *integer* representation in the MMIO data
register -- see (3a) --, I mindlessly added an indiscriminate
byte-swizzling step to the (little endian) guest firmware.
This was a grave error -- it violates (3c) --, but I didn't realize it. I
only saw that the code I otherwise intended for fw_cfg_data_mem_read():
value = 0;
for (i = 0; i < size; ++i) {
value = (value << 8) | fw_cfg_read(s);
}
didn't produce the expected result in the guest.
In true facepalm style, instead of blaming my guest code (which violated
(3c)), I blamed my host code (which was correct). Ultimately, I coded
ldX_he_p() into fw_cfg_data_mem_read(), because that happened to work.
Obviously (...in retrospect) that was wrong. Only because my host happened
to be LE, ldX_he_p() composed the (otherwise incorrect) host value 0x5958
from the fw_cfg string "XY". And that happened to compensate for the bogus
indiscriminate byte-swizzling in my guest code.
Clearly the current code leaks the host endianness through to the guest,
which is wrong. Any device should work the same regardless of host
endianness.
The solution is to compose the host-endian representation (2) of the big
endian interpretation (3a, 3b) of the fw_cfg string, and to drop the wrong
byte-swizzling in the guest (3c).
Brown paper bag time for me.

The crypto emulation code in target-arm/crypto_helper.c never worked
correctly on big endian hosts, due to the fact that it uses a union
of array types to convert between the native VFP register size (64
bits) and the types used in the algorithms (bytes and 32 bit words)
We cannot just swab between LE and BE when reading and writing the
registers, as the SHA code performs word additions, so instead, add
array accessors for the CRYPTO_STATE type whose LE and BE specific
implementations ensure that the correct array elements are referenced.

libvirt prefers opening the TCP connection itself, for two reasons.
First, connection failed errors can be detected easier, without having
to parse qemu's error output.
Second, libvirt might be asked to secure the transfer by tunnelling the
communication through an TLS layer.
Therefore, libvirt opens the TCP connection itself and passes an FD to qemu
using QMP and a POSIX-specific mechanism.
Hence, in order to make the reverse-path work in such cases, qemu needs to
distinguish if the transmitted FD is a socket (reverse-path available)
or not (reverse-path might not be available) and use the corresponding
abstraction.

Only free qsb that qemu_bufopen allocated, and also allow
qemu_bufopen accept qsb as input for write operation. It
will make the API more logical:
1.If you create the QEMUSizedBuffer yourself, you need to
free it by using qsb_free() but not depends on other API
like qemu_fclose.
2.allow qemu_bufopen() accept QEMUSizedBuffer as input for
write operation, otherwise, it will be a little strange
for this API won't accept the second parameter.
This brings API change, since there are only 3
users of this API currently, this change only impact the
first one which will be fixed in patch 2 of this patchset,
so I think it is safe to do this change.

Some ancient Linux kernels read from registers 0x09 and 0x3c-3f during
boot. According to the spec these registers are for diag and debug
purposes only. If they are absend qemu aborts on read.

After the next patch, we will move the high parts of AVX and AVX512 registers
in the same array as the SSE registers. This will make it impossible to
memcpy an array of 128-bit values in and out of xmm_regs in one swoop.
Use a for loop instead.
Similarly, always use XMM_Q in translate.c. This avoids introducing bugs
such as the one fixed in the previous patch.

This was accessing an XMM register's low half without going through XMM_Q.

This is happening because an actual logic is performed on the memory
arguments inside the main's switch, disregarding the config file content.
Solved by extracting the logic on a separate function and calling it
after the switch.

Increase maxmem before calling xc_domain_populate_physmap_exact to
avoid the risk of running out of guest memory. This way we can also
avoid complex memory calculations in libxl at domain construction
time.
This patch fixes an abort() when assigning more than 4 NICs to a VM.
