virtio-console: set frontend open permanently for console devs
The virtio-console.c file handles both serial consoles
and interactive consoles, since they're backed by the
same device model.
Since serial devices are expected to be reliable and
need to notify the guest when the backend is opened
or closed, the virtio-console.c file wires up support
for chardev events. This affects both serial consoles
and interactive consoles, using a network connection
based chardev backend such as 'socket', but not when
using a PTY based backend or plain 'file' backends.
When the host side is not connected the handle_output()
method in virtio-serial-bus.c will drop any data sent
by the guest, before it even reaches the virtio-console.c
code. This means that if the chardev has a logfile
configured, the data will never get logged.
Consider for example, configuring a x86_64 guest with a
plain UART serial port
-chardev socket,id=charserial1,host=127.0.0.1,port=9001,server,nowait,logfile=console1.log,logappend=on
-device isa-serial,chardev=charserial1,id=serial1
vs a s390 guest which has to use the virtio-console port
-chardev socket,id=charconsole1,host=127.0.0.1,port=9000,server,nowait,logfile=console2.log,logappend=on
-device virtconsole,chardev=charconsole1,id=console1
The isa-serial one gets data written to the log regardless
of whether a client is connected, while the virtioconsole
one only gets data written to the log when a client is
connected.
There is no need for virtio-serial-bus.c to aggressively
drop the data for console devices, as the chardev code is
prefectly capable of discarding the data itself.
So this patch changes virtconsole devices so that they
are always marked as having the host side open. This
ensures that the guest OS will always send any data it
has (Linux virtio-console hvc driver actually ignores
the host open state and sends data regardless, but we
should not rely on that), and also prevents the
virtio-serial-bus code prematurely discarding data.
The behaviour of virtserialport devices is *not* changed,
only virtconsole, because for the former, it is important
that the guest OSknow exactly when the host side is opened
/ closed so it can do any protocol re-negotiation that may
be required.

vhost-user: Attempt to fix a race with set_mem_table.
The set_mem_table command currently does not seek a reply. Hence, there is
no easy way for a remote application to notify to QEMU when it finished
setting up memory, or if there were errors doing so.
As an example:
(1) Qemu sends a SET_MEM_TABLE to the backend (eg, a vhost-user net
application). SET_MEM_TABLE does not require a reply according to the spec.
(2) Qemu commits the memory to the guest.
(3) Guest issues an I/O operation over a new memory region which was configured on (1).
(4) The application has not yet remapped the memory, but it sees the I/O request.
(5) The application cannot satisfy the request because it does not know about those GPAs.
While a guaranteed fix would require a protocol extension (committed separately),
a best-effort workaround for existing applications is to send a GET_FEATURES
message before completing the vhost_user_set_mem_table() call.
Since GET_FEATURES requires a reply, an application that processes vhost-user
messages synchronously would probably have completed the SET_MEM_TABLE before replying.

There is a regression with the "-cpu" parameter introduced by
the spapr CPU hotplug code: We used to allow to specify a
"CPU family" name with the "-cpu" parameter when running on KVM so
that the user does not need to know the gory details of the exact
CPU version of the host CPU. For example, it was possible to
use "-cpu POWER8" on a POWER8E host CPU. This behavior does not
work anymore with the new hot-pluggable spapr-cpu-core types.
Since libvirt already heavily depends on the old behavior, this
is quite a severe regression in the QEMU parameter interface.

Hard-coding the CPU alias names in the spapr_cores[] array has
two big disadvantages:
1) We register a real type with the CPU alias name in
spapr_cpu_core_register_types() - this prevents us from registering
a CPU family name in kvm_ppc_register_host_cpu_type() with the same
name (as we do it for the non-hotpluggable CPU types).
2) It's quite cumbersome to maintain the aliases here in sync with the
ppc_cpu_aliases list from target-ppc/cpu-models.c.
So let's simply add proper alias lookup to the spapr cpu core code,
too (by checking whether the given model can be used directly, and
if not by trying to look up the given model as an alias name instead).

ppc64: fix compressed dump with pseries kernel
If we don't provide the page size in target-ppc:cpu_get_dump_info(),
the default one (TARGET_PAGE_SIZE, 4KB) is used to create
the compressed dump. It works fine with Macintosh, but not with
pseries as the kernel default page size is 64KB.
Without this patch, if we generate a compressed dump in the QEMU monitor:
(qemu) dump-guest-memory -z qemu.dump
This dump cannot be read by crash:
# crash vmlinux qemu.dump
...
WARNING: cannot translate vmemmap kernel virtual addresses:
commands requiring page structure contents will fail
...
Page_size is used to determine the dumpfile's block size. The
block size needs to be at least the page size, but a multiple of page
size works fine too. For PPC64, linux supports either 4KB or 64KB software
page size. So we define the page_size to 64KB.

timer: set vm_clock disabled default
(commit
80dcfb8532ae76343109a48f12ba8ca1c505c179)
Upon migration, the code use a timer based on vm_clock for 1ns
in the future from post_load to do the event send in case host_connected
differs between migration source and target.
However, it's not guaranteed that the apic is ready to inject irqs into
the guest, and the irq line remained high, resulting in any future interrupts
going unnoticed by the guest as well.
That's because 1) the migration coroutine is not blocked when it get EAGAIN
while reading QEMUFile. 2) The vm_clock is enabled default currently, it doesn't
rely on the calling of vm_start(), that means vm_clock timers can run before
VCPUs are running.
So, let's set the vm_clock disabled default, keep the initial intention of
design for vm_clock timers.
Meanwhile, change the test-aio usecase, using QEMU_CLOCK_REALTIME instead of
QEMU_CLOCK_VIRTUAL as the block code does.

optionrom: fix compilation with mingw docker target
Two fixes are needed. First, mingw does not have -D_FORTIFY_SOURCE,
hence --enable-debug disables optimization. This is not acceptable
for ROMs, which should override CFLAGS to force inclusion of -O2.
Second, PE stores global constructors and destructors using the
following linker script snippet:
___CTOR_LIST__ = .; __CTOR_LIST__ = . ;
LONG (-1);*(.ctors); *(.ctor); *(SORT(.ctors.*)); LONG (0);
___DTOR_LIST__ = .; __DTOR_LIST__ = . ;
LONG (-1); *(.dtors); *(.dtor); *(SORT(.dtors.*)); LONG (0);
The LONG directives cause the .img files to be 16 bytes too large;
the recently added check to signrom.py catches this. To fix this,
replace -T and -e options with a linker script.

linuxboot_dma: avoid guest ABI breakage on gcc vs. clang compilation
Recent GCC compiles linuxboot_dma.c to 921 bytes, while CentOS 6 needs
1029 and clang needs 1527. Because the size of the ROM, rounded to the
next 512 bytes, must match, this causes the API to break between a <1K
ROM and one that is bigger.
We want to make the ROM 1.5 KB in size, but it's better to make clang
produce leaner ROMs, because currently it is worryingly close to the limit.
To fix this prevent clang's happy inlining (which -Os cannot prevent).
This only requires adding a noinline attribute.
Second, the patch makes sure that the ROM has enough padding to prevent
ABI breakage on different compilers. The size is now hardcoded in the file
that is passed to signrom.py, as was the case before commit
6f71b77
("scripts/signrom.py: Allow option ROM checksum script to write the size
header.", 2016-05-23); signrom.py however will still pad the input to
the requested size. This ensures that the padding goes beyond the
next multiple of 512 if necessary, and also avoids the need for
-fno-toplevel-reorder which clang doesn't support. signrom.py can then
error out if the requested size is too small for the actual size of the
compiled ROM.

Prior to
c8721d3 "spapr: Error out when CPU hotplug is attempted on older
pseries machines", attempting to use query-hotpluggable-cpus on pseries-2.6
and earlier machine types would SEGV.
That change fixed that, but due to some unexpected interactions in init
order and a brown-paper-bag worthy failure to test, it accidentally
disabled query-hotpluggable-cpus for all pseries machine types, including
the current one which should allow it.
In fact, query_hotpluggable_cpus needs to be non-NULL when and only when
the dr_cpu_enabled flag in sPAPRMachineClass is set, which makes
dr_cpu_enabled itself redundant.
This patch removes dr_cpu_enabled, instead directly setting
query_hotpluggable_cpus from the machine class_init functions, and using
that to determine the availability of CPU hotplug when necessary.

Follow John Snow recommendation:
Everywhere else ncq_err is used, it is accompanied by a list cleanup
except for ncq_cb, which is the case you are fixing here.
Move the sglist destruction inside of ncq_err and then delete it from
the other two locations to keep it tidy.
Call dma_buf_commit in ide_dma_cb after the early return. Though, this
is also a little wonky because this routine does more than clear the
list, but it is at the moment the centralized "we're done with the
sglist" function and none of the other side effects that occur in
dma_buf_commit will interfere with the reset that occurs from
ide_restart_bh, I think

lower indirect registers to loads and stores off the indirect base into
plain temps.
For an x86_64 host, with sufficient registers, this results in identical

For an i686 host, with insufficient registers, this means that temps can

throttle: Test burst limits lower than the normal limits
This checks that making FOO_max lower than FOO is not allowed.
We could also forbid having FOO_max == FOO, but that doesn't have
any odd side effects and it would require us to update several other
tests, so let's keep it simple.

throttle: Don't allow burst limits to be lower than the normal limits
Setting FOO_max to a value that is lower than FOO does not make
sense, and it produces odd results depending on the value of
FOO_max_length. Although the user should not set that configuration
in the first place it's better to reject it explicitly.

nvme: bump PCI revision
The broken Identify implementation in earlier Qemu versions means we
need to blacklist it from issueing the NVMe 1.1 Identify Namespace List
command. As we want to be able to use it in newer Qemu versions we need
a way to identify those. Bump the PCI revision as a guest visible
indicator of this bug fix.

NVMe 1.1 requires devices to implement a Namespace List subcommand of

also misinterprets it as an Identify Controller request. Due to this
any OS trying to use the Namespace List will fail the probe.

0d978913 changed blockdev-backup to accept arbitrary node names

However, it forgot to make the same change in transactions and to update
