2d4ba6cc74 virtio: Add queue interface to restore avail index from vring used index
In case of backend crash, it is not possible to restore internal
avail index from the backend value as vhost_get_vring_base
callback fails.

This patch provides a new interface to restore internal avail index
from the vring used index, as done by some vhost-user backend on
reconnection.

fc24908e7d blockjob: reimplement block_job_sleep_ns to allow cancellation
This reverts the effects of commit 4afeffc857 ("blockjob: do not allow
coroutine double entry or entry-after-completion", 2017-11-21)

This fixed the symptom of a bug rather than the root cause. Canceling the
wait on a sleeping blockjob coroutine is generally fine, we just need to
make it work correctly across AioContexts.  To do so, use a QEMUTimer
that calls block_job_enter.  Use a mutex to ensure that block_job_enter
synchronizes correctly with block_job_sleep_ns.

e7b47c22e2 osdep.h: Make TIME_MAX handle different time_t types
In our various supported host OSes, the time_t type may be either 32
or 64 bit, and could in theory also be either signed or unsigned.
Notably, in OpenBSD time_t is a 64 bit type even if 'long' is 32
bits, so using LONG_MAX for TIME_MAX is incorrect.

Use an approach suggested by Paolo Bonzini which calculates
the maximum value of the type rather than hardcoding it;
to do this we use the TYPE_MAXIMUM macro from Gnulib.

6133b39f3c coroutine: abort if we try to schedule or enter a pending coroutine
The previous patch fixed a race condition, in which there were
coroutines being executing doubly, or after coroutine deletion.

We can detect common scenarios when this happens, and print an error
message and abort before we corrupt memory / data, or segfault.

This patch will abort if an attempt to enter a coroutine is made while
it is currently pending execution, either in a specific AioContext bh,
or pending execution via a timer.  It will also abort if a coroutine
is scheduled, before a prior scheduled run has occurred.

We cannot rely on the existing co->caller check for recursive re-entry
to catch this, as the coroutine may run and exit with
COROUTINE_TERMINATE before the scheduled coroutine executes.

(This is the scenario that was occurring and fixed in the previous
patch).

This patch also re-orders the Coroutine struct elements in an attempt to
optimize caching.

4afeffc857 blockjob: do not allow coroutine double entry or entry-after-completion
When block_job_sleep_ns() is called, the co-routine is scheduled for
future execution.  If we allow the job to be re-entered prior to the
scheduled time, we present a race condition in which a coroutine can be
entered recursively, or even entered after the coroutine is deleted.

The job->busy flag is used by blockjobs when a coroutine is busy
executing. The function 'block_job_enter()' obeys the busy flag,
and will not enter a coroutine if set.  If we sleep a job, we need to
leave the busy flag set, so that subsequent calls to block_job_enter()
are prevented.

This changes the prior behavior of block_job_cancel() being able to
immediately wake up and cancel a job; in practice, this should not be an
issue, as the coroutine sleep times are generally very small, and the
cancel will occur the next time the coroutine wakes up.

2726627197 exec.c: Factor out before/after actions for notdirty memory writes
The function notdirty_mem_write() has a sequence of actions
it has to do before and after the actual business of writing
data to host RAM to ensure that dirty flags are correctly
updated and we flush any TCG translations for the region.
We need to do this also in other places that write directly
to host RAM, most notably the TCG atomic helper functions.
Pull out the before and after pieces into their own functions.

We use an API where the prepare function stashes the various
bits of information about the write into a struct for the
complete function to use, because in the calls for the atomic
helpers the place where the complete function will be called
doesn't have the information to hand.

b6e70d1d7f hw/arm/aspeed: Unlock SCU when running kernel
The ASPEED hardware contains a lock register for the SCU that disables
any writes to the SCU when it is locked. The machine comes up with the
lock enabled, but on all known hardware u-boot will unlock it and leave
it unlocked when loading the kernel.

This means the kernel expects the SCU to be unlocked. When booting from
an emulated ROM the normal u-boot unlock path is executed. Things don't
go well when booting using the -kernel command line, as u-boot does not
run first.

Change behaviour so that when a kernel is passed to the machine, set the
reset value of the SCU to be unlocked.

0dacea92d2 net: Transmit zero UDP checksum as 0xFFFF
The checksum algorithm used by IPv4, TCP and UDP allows a zero value
to be represented by either 0x0000 and 0xFFFF. But per RFC 768, a zero
UDP checksum must be transmitted as 0xFFFF because 0x0000 is a special
value meaning no checksum.

Substitute 0xFFFF whenever a checksum is computed as zero when
modifying a UDP datagram header. Doing this on IPv4 and TCP checksums
is unnecessary but legal. Add a wrapper for net_checksum_finish() that
makes the substitution.

(We can't just change net_checksum_finish(), as that function is also
used by receivers to verify checksums, and in that case the expected
value is always 0x0000.)

5e003f17ec block: Make bdrv_next() keep strong references
On one hand, it is a good idea for bdrv_next() to return a strong
reference because ideally nearly every pointer should be refcounted.
This fixes intermittent failure of iotest 194.

On the other, it is absolutely necessary for bdrv_next() itself to keep
a strong reference to both the BB (in its first phase) and the BDS (at
least in the second phase) because when called the next time, it will
dereference those objects to get a link to the next one.  Therefore, it
needs these objects to stay around until then.  Just storing the pointer
to the next in the iterator is not really viable because that pointer
might become invalid as well.

Both arguments taken together means we should probably just invoke
bdrv_ref() and blk_ref() in bdrv_next().  This means we have to assert
that bdrv_next() is always called from the main loop, but that was
probably necessary already before this patch and judging from the
callers, it also looks to actually be the case.

Keeping these strong references means however that callers need to give
them up if they decide to abort the iteration early.  They can do so
through the new bdrv_next_cleanup() function.

7b8be49d36 NUMA: Enable adding NUMA node implicitly
Linux and Windows need ACPI SRAT table to make memory hotplug work properly,
however currently QEMU doesn't create SRAT table if numa options aren't present
on CLI.

Which breaks both linux and windows guests in certain conditions:
 * Windows: won't enable memory hotplug without SRAT table at all
 * Linux: if QEMU is started with initial memory all below 4Gb and no SRAT table
   present, guest kernel will use nommu DMA ops, which breaks 32bit hw drivers
   when memory is hotplugged and guest tries to use it with that drivers.

Fix above issues by automatically creating a numa node when QEMU is started with
memory hotplug enabled but without '-numa' options on CLI.
(PS: auto-create numa node only for new machine types so not to break migration).

Which would provide SRAT table to guests without explicit -numa options on CLI
and would allow:
 * Windows: to enable memory hotplug
 * Linux: switch to SWIOTLB DMA ops, to bounce DMA transfers to 32bit allocated
   buffers that legacy drivers/hw can handle.

9fa99d2519 hw/pci-host: Fix x86 Host Bridges 64bit PCI hole
Currently there is no MMIO range over 4G
reserved for PCI hotplug. Since the 32bit PCI hole
depends on the number of cold-plugged PCI devices
and other factors, it is very possible is too small
to hotplug PCI devices with large BARs.

Fix it by reserving 2G for I4400FX chipset
in order to comply with older Win32 Guest OSes
and 32G for Q35 chipset.

Even if the new defaults of pci-hole64-size will appear in
"info qtree" also for older machines, the property was
not implemented so no changes will be visible to guests.

Note this is a regression since prev QEMU versions had
some range reserved for 64bit PCI hotplug.

dcb556fc6a xics/kvm: synchonize state before 'info pic'
When using the emulated XICS, the 'info pic' monitor command shows:

CPU 0 XIRR=ff000000 ((nil)) PP=ff MFRR=ff
ICS 1000..13ff 0x10040060340
  1000 MSI 05 00
  1001 MSI 05 00
  1002 MSI 05 00
  1003 MSI ff 00
  1004 LSI ff 00
  1005 LSI ff 00
  1006 LSI ff 00
  1007 LSI ff 00
  1008 MSI 05 00
  1009 MSI 05 00
  100a MSI 05 00
  100b MSI 05 00
  100c MSI 05 00

but when using the in-kernel XICS with the very same guest, we get:

CPU 0 XIRR=00000000 ((nil)) PP=ff MFRR=ff
ICS 1000..13ff 0x10032e00340
  1000 MSI ff 00
  1001 MSI ff 00
  1002 MSI ff 00
  1003 MSI ff 00
  1004 LSI ff 00
  1005 LSI ff 00
  1006 LSI ff 00
  1007 LSI ff 00
  1008 MSI ff 00
  1009 MSI ff 00
  100a MSI ff 00
  100b MSI ff 00
  100c MSI ff 00

ie, all irqs are masked and XIRR is null, while we should get the
same output as with the emulated XICS.

If the guest is then migrated, 'info pic' shows the expected values
on both source and destination.

The problem is that QEMU doesn't synchronize with KVM before printing
the XICS state. Migration happens to fix the output because it enforces
synchronization with KVM.

To fix the invalid output of 'info pic', this patch introduces a new
synchronize_state operation for both ICPStateClass and ICSStateClass.
The ICP operation relies on run_on_cpu() in order to kick the vCPU
and avoid sleeping on KVM_GET_ONE_REG.

d25f2a7227 accel/tcg/translate-all: expand cpu_restore_state addr check
We are still seeing signals during translation time when we walk over
a page protection boundary. This expands the check to ensure the host
PC is inside the code generation buffer. The original suggestion was
to check versus tcg_ctx.code_gen_ptr but as we now segment the
translation buffer we have to settle for just a general check for
being inside.

I've also fixed up the declaration to make it clear it can deal with
invalid addresses. A later patch will fix up the call sites.

7264961934 hw: add .min_cpus and .default_cpus fields to machine_class
max_cpus needs to be an upper bound on the number of vCPUs
initialized; otherwise TCG region initialization breaks.

Some boards initialize a hard-coded number of vCPUs, which is not
captured by the global max_cpus and therefore breaks TCG initialization.
Fix it by adding the .min_cpus field to machine_class.

This commit also changes some user-facing behaviour: we now die if
-smp is below this hard-coded vCPU minimum instead of silently
ignoring the passed -smp value (sometimes announcing this by printing
a warning). However, the introduction of .default_cpus lessens the
likelihood that users will notice this: if -smp isn't set, we now
assign the value in .default_cpus to both smp_cpus and max_cpus. IOW,
if a user does not set -smp, they always get a correct number of vCPUs.

This change fixes 3468b59 ("tcg: enable multiple TCG contexts in
softmmu", 2017-10-24), which broke TCG initialization for some
ARM boards.

2dda635410 qom: move CPUClass.tcg_initialize to a global
55c3cee ("qom: Introduce CPUClass.tcg_initialize", 2017-10-24)
introduces a per-CPUClass bool that we check so that the target CPU
is initialized for TCG only once. This works well except when
we end up creating more than one CPUClass, in which case we end
up incorrectly initializing TCG more than once, i.e. once for
each CPUClass.

This can be replicated with:
  $ aarch64-softmmu/qemu-system-aarch64 -machine xlnx-zcu102 -smp 6 \
      -global driver=xlnx,,zynqmp,property=has_rpu,value=on
In this case the class name of the "RPUs" is prefixed by "cortex-r5-",
whereas the "regular" CPUs are prefixed by "cortex-a53-". This
results in two CPUClass instances being created.

Fix it by introducing a static variable, so that only the first
target CPU being initialized will initialize the target-dependent
part of TCG, regardless of CPUClass instances.

efdc0c103d nbd: Fix struct name for structured reads
A closer read of the NBD spec shows that a structured reply chunk
for a hole is not quite identical to the prefix of a data chunk,
because the hole has to also send a 32-bit size field.  Although
we do not yet send holes, we should fix the misleading information

ab37bfc7d6 pci-assign: Remove
Legacy PCI device assignment has been removed from Linux in 4.12,
and had been deprecated 2 years ago there.  We can remove it from
QEMU as well.

The ROM loading code was shared with Xen PCI passthrough, so move
it to hw/xen.

badd3d62c6 sun4m: change TYPE_SUN4M_IOMMU macro from "iommu" to "sun4m-iommu"
This is a legacy artifact from when the sun4m IOMMU implementation was
the only IOMMU available within QEMU.

4ca3d368d2 sparc32_dma: remove is_ledma hack and replace with memory region alias
This hack originated from before the memory region API was introduced, and
increased the size of the ledma DMA device to capture incorrect accesses
beyond the end of the ledma device. A full analysis can be found on Artyom's
blog at http://tyom.blogspot.co.uk/2010/10/bug-in-all-solaris-versions-after-57.html.

With the memory API we can now simply alias the incorrect access onto its
intended destination allowing us to remove the hack.

6aa62ed6b8 sparc32_dma: introduce new SPARC32_DMA type container object
Create a new SPARC32_DMA container object (including an appropriate container
memory region) and add instances of the SPARC32_ESPDMA_DEVICE and
SPARC32_LEDMA_DEVICE as child objects. The benefit is that most of the gpio
wiring complexity between esp/espdma and lance/ledma is now hidden within the
SPARC32_DMA realize function.

Since the sun4m IOMMU is already QOMified we can find a reference to
it using object_resolve_path_type() allowing us to completely remove all external
references to the iommu pointer.

Finally we rework sun4m's sparc32_dma_init() to invoke the new SPARC32_DMA object
and wire up the remaining board memory regions/IRQs.
