e6e40f80cd qemu-options: Remove deprecated option -clock
The option is only a dummy since a long time. We've finally deprecated
it in QEMU v3.0, so it's time to remove it now.

292fa230cb Remove deprecated -enable-hax option
Our command line interface is really quite overcrowded, we should avoid
duplicated options that do the same thing in just a slightly different
way. "-accel hax" is shorter and more generic that "-enable-hax", so
there is really no real usage for the latter option. "-enable-hax" has
been deprecated since two releases, and nobody complained so far, so
it's time to remove this now.

93aee84f57 9p: remove support for the "handle" backend
The "handle" fsdev backend was deprecated in QEMU 2.12.0 with:

commit db3b3c7281
Author: Greg Kurz <groug@kaod.org>
Date:   Mon Jan 8 11:18:23 2018 +0100

    9pfs: deprecate handle backend

    This backend raise some concerns:

    - doesn't support symlinks
    - fails +100 tests in the PJD POSIX file system test suite [1]
    - requires the QEMU process to run with the CAP_DAC_READ_SEARCH
      capability, which isn't recommended for security reasons

    This backend should not be used and wil be removed. The 'local'
    backend is the recommended alternative.

c0188e69d3 bt: Mark the bluetooth subsystem as deprecated
It has been unmaintained since years, and there were only trivial or
tree-wide changes to the related files since many years, so the
code is likely very bitrotten and broken. For example the following
segfaults as soon as as you press a key:

 qemu-system-x86_64 -usb -device usb-bt-dongle -bt hci -bt device:keyboard

Since we are not aware of anybody using bluetooth with the current
version of QEMU, let's mark the subsystem as deprecated, with a special
request for the users to write to the qemu-devel mailing list in case
they still use it (so we could revert the deprecation status in that
case).

80668d0fb7 qcow2: Increase the default upper limit on the L2 cache size
The upper limit on the L2 cache size is increased from 1 MB to 32 MB
on Linux platforms, and to 8 MB on other platforms (this difference is
caused by the ability to set intervals for cache cleaning on Linux
platforms only).

This is done in order to allow default full coverage with the L2 cache
for images of up to 256 GB in size (was 8 GB). Note, that only the
needed amount to cover the full image is allocated. The value which is
changed here is just the upper limit on the L2 cache size, beyond which
it will not grow, even if the size of the image will require it to.

b749562d98 qcow2: Assign the L2 cache relatively to the image size
Sufficient L2 cache can noticeably improve the performance when using
large images with frequent I/O.

Previously, unless 'cache-size' was specified and was large enough, the
L2 cache was set to a certain size without taking the virtual image size
into account.

Now, the L2 cache assignment is aware of the virtual size of the image,
and will cover the entire image, unless the cache size needed for that is
larger than a certain maximum. This maximum is set to 1 MB by default
(enough to cover an 8 GB image with the default cluster size) but can
be increased or decreased using the 'l2-cache-size' option. This option
was previously documented as the *maximum* L2 cache size, and this patch
makes it behave as such, instead of as a constant size. Also, the
existing option 'cache-size' can limit the sum of both L2 and refcount
caches, as previously.

ec86faa934 vnc: remove support for deprecated tls, x509, x509verify options
The 'tls-creds' option accepts the name of a TLS credentials
object. This replaced the usage of 'tls', 'x509' and 'x509verify'
options in 2.5.0. These deprecated options were grandfathered in
when the deprecation policy was introduded in 2.10.0, so can now
finally be removed.

a4de8552b2 hostmem-file: add the 'pmem' option
When QEMU emulates vNVDIMM labels and migrates vNVDIMM devices, it
needs to know whether the backend storage is a real persistent memory,
in order to decide whether special operations should be performed to
ensure the data persistence.

This boolean option 'pmem' allows users to specify whether the backend
storage of memory-backend-file is a real persistent memory. If
'pmem=on', QEMU will set the flag RAM_PMEM in the RAM block of the
corresponding memory region. If 'pmem' is set while lack of libpmem
support, a error is generated.

dfaa7d50b0 Document command line options with single dash
QEMU options have a single dash (but also work as double dash for
convenience and compatibility). Most options are listed with single
dash in command line help but some were listed with two dashes.
Normalize these to have the same format as the others.

Left --preconfig as that is mentioned as double dash everywhere so I
assume that is the preferred form for that.

e1a6dc91dd crypto: Implement TLS Pre-Shared Keys (PSK).
Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS
connections than using certificates.  It requires only a simple secret
key:

  $ mkdir -m 0700 /tmp/keys
  $ psktool -u rjones -p /tmp/keys/keys.psk
  $ cat /tmp/keys/keys.psk
  rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc

The key can be secretly shared between clients and servers.  Clients
must specify the directory containing the "keys.psk" file and a
username (defaults to "qemu").  Servers must specify only the
directory.

Example NBD client:

  $ qemu-img info \
    --object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \
    --image-opts \
    file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/

Example NBD server using qemu-nbd:

  $ qemu-nbd -t -x / \
    --object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \
    --tls-creds tls0 \
    image.qcow2

Example NBD server using nbdkit:

  $ nbdkit -n -e / -fv \
    --tls=on --tls-psk=/tmp/keys/keys.psk \
    file file=disk.img

6f131f13e6 kvm: support -overcommit cpu-pm=on|off
With this flag, kvm allows guest to control host CPU power state.  This
increases latency for other processes using same host CPU in an
unpredictable way, but if decreases idle entry/exit times for the
running VCPU, so to use it QEMU needs a hint about whether host CPU is
overcommitted, hence the flag name.

Follow-up patches will expose this capability to guest
(using mwait leaf).

c44df2ff9b Deprecate the -enable-hax option
We currently have got three ways of turning on the HAX accelerator:
"-machine accel=hax", "-accel hax" and "-enable-hax". That's really
confusing and overloaded. Since "-accel" is our preferred way to enable
an accelerator nowadays, and "-accel hax" is even less to type than
"-enable-hax", let's deprecate the "-enable-hax" option now.

Note: While "-enable-kvm" is available since a long time and can hardly be
removed since it is used in a lot of upper layer tools and scripts, the
"-enable-hax" option is still rather new and not very widespread yet, so
I think that it should be OK if we remove this in a couple of releases again
(we'll see whether someone complains after seeing the deprecation message -
then we could still reconsider to keep it if there a well-founded reasons).

047f7038f5 cli: add --preconfig option
This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state,
allowing the configuration of QEMU from QMP before the machine jumps
into board initialization code of machine_run_board_init()

The intent is to allow management to query machine state and additionally
configure it using previous query results within one QEMU instance
(i.e. eliminate the need to start QEMU twice, 1st to query board specific
parameters and 2nd for actual VM start using query results for
additional parameters).

The new option complements -S option and could be used with or without
it. The difference is that -S pauses QEMU when the machine is completely
initialized with all devices wired up and ready to execute guest code
(QEMU needs only to unpause VCPUs to let guest execute its code),
while the "preconfig" option pauses QEMU early before board specific init
callback (machine_run_board_init) is executed and allows the configuration
of machine parameters which will be used by board init code.

When early introspection/configuration is done, command 'exit-preconfig'
should be used to exit RUN_STATE_PRECONFIG and transition to the next
requested state (i.e. if -S is used then QEMU will pause the second
time when board/device initialization is completed or start guest
execution if -S isn't provided on CLI)

PS:
Initially 'preconfig' is planned to be used for configuring numa
topology depending on board specified possible cpus layout.
