8de702cb67 semihosting: add qemu_semihosting_console_inc for SYS_READC
Provides a blocking call to read a character from the console using
semihosting.chardev, if specified. This takes some careful command
line options to use stdio successfully as the serial ports, monitor
and semihost all want to use stdio. Here's a sample set of command
line options which share stdio between semihost, monitor and serial
ports:

	qemu \
	-chardev stdio,mux=on,id=stdio0 \
	-serial chardev:stdio0 \
	-semihosting-config enable=on,chardev=stdio0 \
	-mon chardev=stdio0,mode=readline

This creates a chardev hooked to stdio and then connects all of the
subsystems to it. A shorter mechanism would be good to hear about.

4ff5ef9e91 target/arm: only update pc after semihosting completes
Before we introduce blocking semihosting calls we need to ensure we
can restart the system on semi hosting exception. To be able to do
this the EXCP_SEMIHOST operation should be idempotent until it finally
completes. Practically this means ensureing we only update the pc
after the semihosting call has completed.

905db91697 ppc/spapr: Support reboot of secure pseries guest
A pseries guest can be run as a secure guest on Ultravisor-enabled
POWER platforms. When such a secure guest is reset, we need to
release/reset a few resources both on ultravisor and hypervisor side.
This is achieved by invoking this new ioctl KVM_PPC_SVM_OFF from the
machine reset path.

As part of this ioctl, the secure guest is essentially transitioned
back to normal mode so that it can reboot like a regular guest and
become secure again.

This ioctl has no effect when invoked for a normal guest. If this ioctl
fails for a secure guest, the guest is terminated.

bc5fdfc0a1 target/ppc: Handle AIL=0 in ppc_excp_vector_offset
The exception vector offset calculation was moved into a function but
the case when AIL=0 was not checked.

The reason we got away with this is that the sole caller of
ppc_excp_vector_offset checks the AIL before calling the function:

    /* Handle AIL */
    if (ail) {
        ...
        vector |= ppc_excp_vector_offset(cs, ail);

1bbd1511b6 Clean-ups: qom-ify serial and remove QDEV_PROP_PTR
Hi,
 
 QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
 me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
 the pointer points to an Object.
 
 There are a few places where such substitution isn't possible. For
 those places, it seems reasonable to use a specific setter method
 instead, and keep the user_creatable = false. In other places,
 proper usage of qdev or other facilies is the solution.
 
 The serial code wasn't converted to qdev, which makes it a bit more
 archaic to deal with. Let's convert it first, so we can more easily
 embed it from other devices, and re-export some properties and drop
 QDEV_PROP_PTR usage.

ab4c072d2f leon3: use qemu_irq framework instead of callback as property
"set_pin_in" property is used to define a callback mechanism where the
device says "call the callback function, passing it an opaque cookie
and a 32-bit value". We already have a generic mechanism for doing
that, which is the qemu_irq. So we should just use that.

c8fa6079eb arm/arm-powerctl: rebuild hflags after setting CP15 bits in arm_set_cpu_on()
After setting CP15 bits in arm_set_cpu_on() the cached hflags must
be rebuild to reflect the changed processor state. Without rebuilding,
the cached hflags would be inconsistent until the next call to
arm_rebuild_hflags(). When QEMU is compiled with debugging enabled
(--enable-debug), this problem is captured shortly after the first
call to arm_set_cpu_on() for CPUs running in ARM 32-bit non-secure mode:

  qemu-system-arm: target/arm/helper.c:11359: cpu_get_tb_cpu_state:
  Assertion `flags == rebuild_hflags_internal(env)' failed.
  Aborted (core dumped)

96eec6b2b3 target/arm: Prepare generic timer for per-platform CNTFRQ
The ASPEED AST2600 clocks the generic timer at the rate of HPLL. On
recent firmwares this is at 1125MHz, which is considerably quicker than
the assumed 62.5MHz of the current generic timer implementation. The
delta between the value as read from CNTFRQ and the true rate of the
underlying QEMUTimer leads to sticky behaviour in AST2600 guests.

Add a feature-gated property exposing CNTFRQ for ARM CPUs providing the
generic timer. This allows platforms to configure CNTFRQ (and the
associated QEMUTimer) to the appropriate frequency prior to starting the
guest.

As the platform can now determine the rate of CNTFRQ we're exposed to
limitations of QEMUTimer that didn't previously materialise: In the
course of emulation we need to arbitrarily and accurately convert
between guest ticks and time, but we're constrained by QEMUTimer's use
of an integer scaling factor. The effect is QEMUTimer cannot exactly
capture the period of frequencies that do not cleanly divide
NANOSECONDS_PER_SECOND for scaling ticks to time. As such, provide an
equally inaccurate scaling factor for scaling time to ticks so at least
a self-consistent inverse relationship holds.

7def875482 target/arm: Abstract the generic timer frequency
Prepare for SoCs such as the ASPEED AST2600 whose firmware configures
CNTFRQ to values significantly larger than the static 62.5MHz value
currently derived from GTIMER_SCALE. As the OS potentially derives its
timer periods from the CNTFRQ value the lack of support for running
QEMUTimers at the appropriate rate leads to sticky behaviour in the
guest.

Substitute the GTIMER_SCALE constant with use of a helper to derive the
period from gt_cntfrq_hz stored in struct ARMCPU. Initially set
gt_cntfrq_hz to the frequency associated with GTIMER_SCALE so current
behaviour is maintained.

ad18392892 i386: Resolve CPU models to v1 by default
When using `query-cpu-definitions` using `-machine none`,
QEMU is resolving all CPU models to their latest versions.  The
actual CPU model version being used by another machine type (e.g.
`pc-q35-4.0`) might be different.

In theory, this was OK because the correct CPU model
version is returned when using the correct `-machine` argument.

Except that in practice, this breaks libvirt expectations:
libvirt always use `-machine none` when checking if a CPU model
is runnable, because runnability is not expected to be affected
when the machine type is changed.

For example, when running on a Haswell host without TSX,
Haswell-v4 is runnable, but Haswell-v1 is not.  On those hosts,
`query-cpu-definitions` says Haswell is runnable if using
`-machine none`, but Haswell is actually not runnable using any
of the `pc-*` machine types (because they resolve Haswell to
Haswell-v1).  In other words, we're breaking the "runnability
guarantee" we promised to not break for a few releases (see
qemu-deprecated.texi).

To address this issue, change the default CPU model version to v1
on all machine types, so we make `query-cpu-definitions` output
when using `-machine none` match the results when using `pc-*`.
This will change in the future (the plan is to always return the
latest CPU model version if using `-machine none`), but only
after giving libvirt the opportunity to adapt.

fc59d2d870 qemu_log_lock/unlock now preserves the qemu_logfile handle.
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a
handle to unlock.  This allows for changing the handle during logging
and ensures the lock() and unlock() are for the same file.

Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock()
calls (and the log("\n")), since the translator can longjmp out of the
loop if it attempts to translate an instruction in an inaccessible page.

0c115681a5 ppc: make Error **errp const where it is appropriate
Mostly, Error ** is for returning error from the function, so the
callee sets it. However kvmppc_hint_smt_possible gets already filled
errp parameter. It doesn't change the pointer itself, only change the
internal state of referenced Error object. So we can make it Error
*const * errp, to stress the behavior. It will also help coccinelle
script (in future) to distinguish such cases from common errp usage.

While there, rename the function to
kvmppc_error_append_smt_possible_hint().
