kvm: x86: Separately write feature control MSR on reset
If the guest is running in nested mode on system reset, clearing the
feature MSR signals the kernel to leave this mode. Recent kernels
processes this properly, but leave the VCPU state undefined behind. It
is the job of userspace to bring it to a proper shape. Therefore, write
this specific MSR first so that no state transfer gets lost.
This allows to cleanly reset a guest with VMX in use.

roms: Flush icache when writing roms to guest memory
We use the rom infrastructure to write firmware and/or initial kernel
blobs into guest address space. So we're basically emulating the cache
off phase on very early system bootup.
That phase is usually responsible for clearing the instruction cache for
anything it writes into cachable memory, to ensure that after reboot we
don't happen to execute stale bits from the instruction cache.
So we need to invalidate the icache every time we write a rom into guest
address space. We do not need to do this for every DMA since the guest
expects it has to flush the icache manually in that case.
This fixes random reboot issues on e5500 (booke ppc) for me.

VCPU TSC is not cleared by a warm reset (*), which leaves some types of Linux
guests (non-pvops guests and those with the kernel parameter no-kvmclock set)
vulnerable to the overflow in cyc2ns_offset fixed by upstream commit 9993bc635d01a6ee7f6b833b4ee65ce7c06350b1 ("sched/x86: Fix overflow in
cyc2ns_offset").
To put it in a nutshell, if such a Linux guest without the patch above applied
has been up more than 208 days and attempts a warm reset chances are that
the newly booted kernel will panic or hang.
(*) Intel Xeon E5 processors show the same broken behavior due to
the errata "TSC is Not Affected by Warm Reset" (Intel® Xeon®
Processor E5 Family Specification Update - August 2013): "The
TSC (Time Stamp Counter MSR 10H) should be cleared on
reset. Due to this erratum the TSC is not affected by warm
reset."

We previously allocated 32-bits per temp for the next_free_temp entry.
We now allocate 4 bits per temp across the 4 bitmaps.
Using a linked list meant that if a translator is tweeked, resulting in
temps being freed in a different order, that would have follow-on effects
throughout the TB. Always allocating the lowest free temp means that
follow-on effects are minimized, which can make it easier to diff output
when debugging the translators.

The ARM A9 MPCore has a timer that is global to all cores in the cluster.
The timer is shared but each core has a private independent comparator

net: Update netdev peer on link change
When a link change occurs on a backend (like tap), we currently do
not propage such change to the nic. As a result, when someone turns
off a link on a tap device, for instance, then a guest doesn't see
that change and continues to try to send traffic or run DHCP even
though the lower-layer is disconnected. This is OK when the network
is set up as a HUB since the the guest may be connected to other HUB
ports too, but when it's set up as a netdev, it makes thinkgs worse.
The patch addresses this by setting the peers link down only when the
peer is not a HUBPORT device. With this patch, in the following config
-netdev tap,id=net0 -device e1000,mac=XXXXX,netdev=net0
when net0 link is turned off, the guest e1000 shows lower-layer link
down. This allows guests to boot much faster in such configurations.
With windows guest, it also allows the network to recover properly
since windows will not configure the link-local IPv4 address, and
when the link is turned on, the proper address address is configured.

This patch adds support for a network backend based on netmap.
netmap is a framework for high speed packet I/O. You can use it
to build extremely fast traffic generators, monitors, software
switches or network middleboxes. Its companion software switch
VALE lets you interconnect virtual machines.
netmap and VALE are implemented as a non-intrusive kernel module,
support NICs from multiple vendors, are part of standard FreeBSD
distributions and available in source format for Linux too.
To compile QEMU with netmap support, use the following configure
options:
./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys
where "/path/to/netmap" contains the netmap source code, available at
http://info.iet.unipi.it/~luigi/netmap/
The same webpage contains more information about the netmap project
(together with papers and presentations).

g_warn_if_reached was added in glib 2.16, and g_byte_array_unref is
supported since glib 2.22. QEMU requires glib 2.12, so both names must
not be used.
Instead of showing a warning for code which should not be reached,
vscclient better stop running, so g_warn_if_reached is not useful for
vscclient.
In libcacard/vsclient.c, g_byte_array_unref can be replaced by
g_byte_array_free. This is not generally true, so adding a compatibility
layer in include/glib-compat.h is no option here.

This patch drops a special case where aio_poll(ctx, true) returns false

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

} 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.

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.
Updates seabios to git master snapshot. seabios is in freeze now,
update to final 1.7.4 will follow later this year.
Summary of major changes:
* Support for acpi table loading from qemu.
* Support for the xhci host adapter.
* Support for the pvscsi HBA.
* Various minor bug fixes.
* Lots of cleanups.

Fix cpuid leaf 0x0d which incorrectly parsed eax and ebx.

field contained the size _and_ was stored in the register that
is supposed to hold the size (eax), and likewise the .size field

supposed to hold the offset (ebx).

qemu-img: dynamically adjust iobuffer size during convert
since the convert process is basically a sync operation it might
be benificial in some case to change the hardcoded I/O buffer
size to a greater value.
This patch increases the I/O buffer size if the output
driver advertises an optimal transfer length or discard alignment
that is greater than the default buffer size of 2M.
