cutils: add avx2 instruction optimization
buffer_find_nonzero_offset() is a hot function during live migration.
Now it use SSE2 instructions for optimization. For platform supports
AVX2 instructions, use AVX2 instructions for optimization can help
to improve the performance of buffer_find_nonzero_offset() about 30%
comparing to SSE2.
Live migration can be faster with this optimization, the test result
shows that for an 8GiB RAM idle guest just boots, this patch can help
to shorten the total live migration time about 6%.
This patch use the ifunc mechanism to select the proper function when
running, for platform supports AVX2, execute the AVX2 instructions,
else, execute the original instructions.

input: linux evdev support
This patch adds support for reading input events directly from linux
evdev devices and forward them to the guest. Unlike virtio-input-host
which simply passes on all events to the guest without looking at them
this will interpret the events and feed them into the qemu input
subsystem.
Therefore this is limited to what the qemu input subsystem and the
emulated input devices are able to handle. Also there is no support for
absolute coordinates (tablet/touchscreen). So we are talking here about
basic mouse and keyboard support.
The advantage is that it'll work without virtio-input drivers in the
guest, the events are delivered to the usual ps/2 or usb input devices
(depending on what the machine happens to have). And for keyboards
qemu is able to switch the keyboard between guest and host on hotkey.
The hotkey is hard-coded for now (both control keys), initialy the
guest owns the keyboard.
Probably most useful when assigning vga devices with vfio and using a
physical monitor instead of vnc/spice/gtk as guest display.
Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command
line. Note that udev has rules which populate /dev/input/by-{id,path}
with static names, which might be more convinient to use.

- Commit

- etc.

qapi-visit: Expose visit_type_FOO_members()
Dan Berrange reported a case where he needs to work with a
QCryptoBlockOptions union type using the OptsVisitor, but only
visit one of the branches of that type (the discriminator is not
visited directly, but learned externally). When things were
boxed, it was easy: just visit the variant directly, which took
care of both allocating the variant and visiting its members, then
store that pointer in the union type. But now that things are
unboxed, we need a way to visit the members without allocation,
done by exposing visit_type_FOO_members() to the user.
Before the patch, we had quite a bit of code associated with
object_members_seen to make sure that a declaration of the helper
was in scope before any use of the function. But now that the
helper is public and declared in the header, the .c file no
longer needs to worry about topological sorting (the helper is
always in scope), which leads to some nice cleanups.

qmp-shell: fix pretty printing of JSON responses
Pretty printing of JSON responses is important to be able to understand
large responses from query commands in particular. Unfortunately this
was broken during the addition of the verbose flag in
commit
1ceca07e48ead0dd2e41576c81d40e6a91cafefd
Author: John Snow <jsnow@redhat.com>
Date: Wed Apr 29 15:14:04 2015 -0400
scripts: qmp-shell: Add verbose flag
This is because that change turned the python data structure into a
formatted JSON string before the pretty print was given it. So we're
just pretty printing a string, which is a no-op.
The original pretty printer would output python objects.
(QEMU) query-chardev
{ u'return': [ { u'filename': u'vc',
u'frontend-open': False,
u'label': u'parallel0'},
{ u'filename': u'vc',
u'frontend-open': True,
u'label': u'serial0'},
{ u'filename': u'unix:/tmp/qemp,server',
u'frontend-open': True,
u'label': u'compat_monitor0'}]}
This fixes the problem by switching to outputting pretty formatted JSON
text instead. This has the added benefit that the pretty printed output
is now valid JSON text. Due to the way the verbose flag was handled, the
pretty printing now applies to the command sent, as well as its response:
(QEMU) query-chardev
{
"execute": "query-chardev",
"arguments": {}
}
{
"return": [
{
"frontend-open": false,

target-arm: Only trap SRS from S-EL1 if specified mode is MON
Commit
cbc0326b6fb9 caused SRS instructions executed from Secure
EL1 to trap to EL3 even if the specified mode was not monitor mode.
According to the ARMv8 Architecture reference manual [F6.1.203], ALL
of the following conditions need to be met for SRS to trap to EL3:
* It is executed at Secure PL1.
* The specified mode is monitor mode.
* EL3 is using AArch64.
Correct the condition governing the trap to EL3 to check the
specified mode.

hw/intc/arm_gic.c: Implement GICv2 GICC_DIR
The GICv2 introduces a new CPU interface register GICC_DIR, which
allows an OS to split the "priority drop" and "deactivate interrupt"
parts of interrupt completion. Implement this register.
(Note that the register is at offset 0x1000 in the CPU interface,

arm: boot: Support big-endian elfs
Support ARM big-endian ELF files in system-mode emulation. When loading
an elf, determine the endianness mode expected by the elf, and set the

With this, big-endian modes are now fully supported via system-mode LE,
so there is no need to restrict the elf loading to the TARGET

loader: Add data swap option to load-elf
Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.
The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.
As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

hw/arm/virt: Assume EL3 boot rom will handle PSCI if one is provided
If the user passes us an EL3 boot rom, then it is going to want to
implement the PSCI interface itself. In this case, disable QEMU's
internal PSCI implementation so it does not get in the way, and
instead start all CPUs in an SMP configuration at once (the boot
rom will catch them all and pen up the secondaries until needed).
The boot rom code is also responsible for editing the device tree
to include any necessary information about its own PSCI implementation
before eventually passing it to a NonSecure guest.
(This "start all CPUs at once" approach is what both ARM Trusted
Firmware and UEFI expect, since it is what the ARM Foundation Model
does; the other approach would be to provide some emulated hardware
for "start the secondaries" but this is simplest.)
This is a compatibility break, but I don't believe that anybody
was using a secure boot ROM with an SMP configuration. Such a setup
would be somewhat broken since there was nothing preventing nonsecure
guest code from calling the QEMU PSCI function to start up a secondary
core in a way that completely bypassed the secure world.

hangover from the vexpress-a15 board, and there's no inherent reason

We choose 255GB because the available space we currently have

want to paint ourselves into a corner by assigning it all to
RAM. So we make half of it available for RAM, with the 256GB..512GB
range available for future non-RAM expansion purposes.
If we need to provide more RAM to VMs in the future then we need to:
* allocate a second bank of RAM starting at 2TB and working up
* fix the DT and ACPI table generation code in QEMU to correctly
report two split lumps of RAM to the guest
* fix KVM in the host kernel to allow guests with >40 bit address spaces
The last of these is obviously the trickiest, but it seems
