      s390x/kvm: fix cmma reset for KVM · 0cf4d747
      由 Christian Borntraeger 提交于 
      We must reset the CMMA states for normal memory (when not on mem path),
but the current code does the opposite. This was unnoticed for some time
as the kernel since 4.6 also had a bug which mostly disabled the paging
optimizations.

      Makefile: Add qemu-doc.txt to distclean and dependencies · d5e85105
      由 Peter Maydell 提交于 
      When qemu-doc.txt was added as a new output format in
commit f8bab10b, it was not added to either the
list of files to remove in distclean or to the dependency
line that forces qemu-options.texi to be built before
attempting to build qemu-doc.*.

In particular, the missing dependency meant that on
some platforms (notably OSX hosts) we would try to
build qemu-doc.txt before qemu-options.texi had been
fully written out, and then makeinfo would complain
about missing cross-reference targets.

      kvm: Allow invtsc migration if tsc-khz is set explicitly · d99569d9
      由 Eduardo Habkost 提交于 
      We can safely allow a VM to be migrated with invtsc enabled if
tsc-khz is set explicitly, because:
* QEMU already refuses to start if it can't set the TSC frequency
  to the configured value.
* Management software is already required to keep device
  configuration (including CPU configuration) the same on
  migration source and destination.

      hw/core/null-machine: Add the possibility to instantiate a CPU and RAM · 3964ec6c
      由 Thomas Huth 提交于 
      Sometimes it is useful to have just a machine with CPU and RAM, without
any further hardware in it, e.g. if you just want to do some instruction
debugging for TCG with a remote GDB attached to QEMU, or run some embedded
code with the "-semihosting" QEMU parameter. qemu-system-m68k already
features a "dummy" machine, and xtensa a "sim" machine for exactly this
purpose.
All target architectures have nowadays also a "none" machine, which would
be a perfect match for this, too - but it currently does not allow to add
CPU and RAM yet. Thus let's add these possibilities in a generic way to the
"none" machine, too, so that we hopefully do not need additional "dummy"
machines in the future anymore (and maybe can also get rid of the already
existing "dummy"/"sim" machines one day).
Note that the default behaviour of the "none" machine is not changed, i.e.
no CPU and no RAM is instantiated by default. You have explicitely got to
specify the CPU model with "-cpu" and the amount of RAM with "-m" to get
these new features.

      qemu-options: Rename variables on the -numa "cpus" option · e0ee9fd0
      由 Eduardo Habkost 提交于 
      Use @var{firstcpu} and @var{lastcpu} to make the metasyntatic
variables a bit clearer. While doing this, use @var only around
the metasyntatic variables, not including the square brackets and
hyphen.

The semantics of the "cpus" option will be clarified by rewriting
the whole -numa documentation in a follow-up patch.
