57065a70d0 s390x/css: introduce css data stream
This is a preparation for introducing handling for indirect data
addressing and modified indirect data addressing (CCW). Here we introduce
an interface which should make the addressing scheme transparent for the
client code. Here we implement only the basic scheme (no IDA or MIDA).

947a38bd6f s390x/kvm: fix and cleanup storing CPU status
env->psa is a 64bit value, while we copy 4 bytes into the save area,
resulting always in 0 getting stored.

Let's try to reduce such errors by using a proper structure. While at
it, use correct cpu->be conversion (and get_psw_mask()), as we will be
reusing this code for TCG soon.

7705c75048 s390x/tcg: add basic MSA features
The STFLE bits for the MSA (extension) facilities simply indicate that
the respective instructions can be executed. The QUERY subfunction can then
be used to identify which features exactly are available.

Availability of subfunctions can also vary on real hardware. For now, we
simply implement a CPU model without any available subfunctions except
QUERY (which is always around).

As all MSA functions behave quite similarly, we can use one translation
handler for now. Prepare the code for implementation of actual subfunctions.

At least MSA is helpful for now, as older Linux kernels require this
facility when compiled for a z9 model. Allow to enable the facilities
for the qemu cpu model.

f69a8bde29 io: send proper HTTP response for websocket errors
When any error occurs while processing the websockets handshake,
QEMU just terminates the connection abruptly. This is in violation
of the HTTP specs and does not help the client understand what they
did wrong. This is particularly bad when the client gives the wrong
path, as a "404 Not Found" would be very helpful.

Refactor the handshake code so that it always sends a response to
the client unless there was an I/O error.

dfbee78db8 vfio/pci: Add NVIDIA GPUDirect Cliques support
NVIDIA has defined a specification for creating GPUDirect "cliques",
where devices with the same clique ID support direct peer-to-peer DMA.
When running on bare-metal, tools like NVIDIA's p2pBandwidthLatencyTest
(part of cuda-samples) determine which GPUs can support peer-to-peer
based on chipset and topology.  When running in a VM, these tools have
no visibility to the physical hardware support or topology.  This
option allows the user to specify hints via a vendor defined
capability.  For instance:

  <qemu:commandline>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.hostdev0.x-nv-gpudirect-clique=0'/>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.hostdev1.x-nv-gpudirect-clique=1'/>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.hostdev2.x-nv-gpudirect-clique=1'/>
  </qemu:commandline>

This enables two cliques.  The first is a singleton clique with ID 0,
for the first hostdev defined in the XML (note that since cliques
define peer-to-peer sets, singleton clique offer no benefit).  The
subsequent two hostdevs are both added to clique ID 1, indicating
peer-to-peer is possible between these devices.

QEMU only provides validation that the clique ID is valid and applied
to an NVIDIA graphics device, any validation that the resulting
cliques are functional and valid is the user's responsibility.  The
NVIDIA specification allows a 4-bit clique ID, thus valid values are
0-15.

f708a5e71c aio: fix assert when remove poll during destroy
After iothread is enabled internally inside QEMU with GMainContext, we
may encounter this warning when destroying the iothread:

(qemu-system-x86_64:19925): GLib-CRITICAL **: g_source_remove_poll:
 assertion '!SOURCE_DESTROYED (source)' failed

The problem is that g_source_remove_poll() does not allow to remove one
source from array if the source is detached from its owner
context. (peterx: which IMHO does not make much sense)

Fix it on QEMU side by avoid calling g_source_remove_poll() if we know
the object is during destruction, and we won't leak anything after all
since the array will be gone soon cleanly even with that fd.

5b3ac23fee iothread: delay the context release to finalize
When gcontext is used with iothread, the context will be destroyed
during iothread_stop().  That's not good since sometimes we would like
to keep the resources until iothread is destroyed, but we may want to
stop the thread before that point.

Delay the destruction of gcontext to iothread finalize.  Then we can do:

  iothread_stop(thread);
  some_cleanup_on_resources();
  iothread_destroy(thread);

We may need this patch if we want to run chardev IOs in iothreads and
hopefully clean them up correctly.  For more specific information,
please see 2b316774f6 ("qemu-char: do not operate on sources from
finalize callbacks").

11748ba72e kvm: check KVM_CAP_NR_VCPUS with kvm_vm_check_extension()
On a modern server-class ppc host with the following CPU topology:

Architecture:          ppc64le
Byte Order:            Little Endian
CPU(s):                32
On-line CPU(s) list:   0,8,16,24
Off-line CPU(s) list:  1-7,9-15,17-23,25-31
Thread(s) per core:    1

If both KVM PR and KVM HV loaded and we pass:

        -machine pseries,accel=kvm,kvm-type=PR -smp 8

We expect QEMU to warn that this exceeds the number of online CPUs:

Warning: Number of SMP cpus requested (8) exceeds the recommended
 cpus supported by KVM (4)
Warning: Number of hotpluggable cpus requested (8) exceeds the
 recommended cpus supported by KVM (4)

but nothing is printed...

This happens because on ppc the KVM_CAP_NR_VCPUS capability is VM
specific  ndreally depends on the KVM type, but we currently use it
as a global capability. And KVM returns a fallback value based on
KVM HV being present. Maybe KVM on POWER shouldn't presume anything
as long as it doesn't have a VM, but in all cases, we should call
KVM_CREATE_VM first and use KVM_CAP_NR_VCPUS as a VM capability.

This patch hence changes kvm_recommended_vcpus() accordingly and
moves the sanity checking of smp_cpus after the VM creation.

It is okay for the other archs that also implement KVM_CAP_NR_VCPUS,
ie, mips, s390, x86 and arm, because they don't depend on the VM
being created or not.

62dd4edaaf kvm: check KVM_CAP_SYNC_MMU with kvm_vm_check_extension()
On a server-class ppc host, this capability depends on the KVM type,
ie, HV or PR. If both KVM are present in the kernel, we will always
get the HV specific value, even if we explicitely requested PR on
the command line.

This can have an impact if we're using hugepages or a balloon device.

Since we've already created the VM at the time any user calls
kvm_has_sync_mmu(), switching to kvm_vm_check_extension() is
enough to fix any potential issue.

It is okay for the other archs that also implement KVM_CAP_SYNC_MMU,
ie, mips, s390, x86 and arm, because they don't depend on the VM being
created or not.

While here, let's cache the state of this extension in a bool variable,
since it has several users in the code, as suggested by Thomas Huth.

f0df84c6c4 watchdog: Allow setting action on the fly
Currently, the only time that users can set watchdog action is at
the start as all we expose is this -watchdog-action command line
argument. This is suboptimal when users want to plug the device
later via monitor. Alternatively, they might want to change the
action for already existing device on the fly.

4c7f4426c4 watchdog.h: Drop local redefinition of actions enum
We already have enum that enumerates all the actions that a
watchdog can take when hitting its timeout: WatchdogAction.
Use that instead of inventing our own.

13787d59cf usb: Use angle brackets for cacard include directive
This is a library header, so angle brackets are more appropriate; also
move the line to before QEMU headers, as is recommended in HACKING.
