hw/ide/microdrive: Mark the dscm1xxxx device with user_creatable = false
QEMU currently aborts with an assertion message when the user is trying
to remove a dscm1xxxx again:

QEMU 2.9.93 monitor - type 'help' for more information

Looks like this device has to be wired up in code and is not meant

ide: ahci: unparent children buses before freeing their memory
Fixes read after freeing error reported

ich9-ahci device creates ide buses and attaches them as QOM children
at realize time, however it forgets to properly clean them up
at unrealize time and frees memory containing these children,
with following call-chain:
qdev_device_add()
object_property_set_bool('realized', true)
device_set_realized()
...
pci_qdev_realize() -> pci_ich9_ahci_realize() -> ahci_realize()
...
s->dev = g_new0(AHCIDevice, ports);
...
AHCIDevice *ad = &s->dev[i];
ide_bus_new(&ad->port, sizeof(ad->port), qdev, i, 1);
^^^ creates bus in memory allocated by above gnew()
and adds it as child propety to ahci device
...
hotplug_handler_plug(); -> goto post_realize_fail;
pci_qdev_unrealize() -> pci_ich9_uninit() -> ahci_uninit()
...
g_free(s->dev);
^^^ free memory that holds children busses
return with error from device_set_realized()
As result later when qdev_device_add() tries to unparent ich9-ahci
after failed device_set_realized(),
object_unparent() -> object_property_del_child()
iterates over existing QOM children including buses added by
ide_bus_new() and tries to unparent them, which causes access to
freed memory where they where located.

qemu.py: avoid writing to stdout/stderr
This module should not write directly to stdout/stderr. Instead, it
should either raise exceptions or just log the messages and let the
callers handle them and decide what to do. For example, scripts could
choose to send the log messages stderr or/and write them to a file if
verbose or debugging mode is enabled.
This patch replaces the writes to stderr by an exception in the
send_fd_scm() when _socket_scm_helper is not set or not present. In the
same method, the subprocess Popen will now redirect the stdout/stderr to
logging.debug instead of writing to system stderr. As consequence, since
the Popen.communicate() is now used (in order to get the stdout), the
further call to wait() became redundant and was replaced by
Popen.returncode.
The shutdown() message on negative exit code will now be logged
to logging.warn instead of written to system stderr.

test-qga: Kill broken and dead QGA_TEST_SIDE_EFFECTING code
Back when the test was introduced, in commit
62c39b307, the
test was set up to run qemu-ga directly on the host performing
the test, and defaults to limiting itself to safe commands. At
the time, it was envisioned that setting QGA_TEST_SIDE_EFFECTING
in the environment could cover a few more commands, while noting
the potential danger of those side effects running in the host.
But this has NEVER been tested: if you enable the environment
variable, the test WILL fail. One obvious reason: if you are not
running as root, you'll probably get a permission failure when
trying to freeze the file systems, or when changing system time.
Less obvious: if you run the test as root (wow, you're brave), you
could end up hanging if the test tries to log things to a
temporarily frozen filesystem. But the cutest reason of all: if
you get past the above hurdles, the test uses invalid JSON in
test_qga_fstrim() (missing '' around the dictionary key 'minimum'),
and will thus fail an assertion in qmp_fd().
Rather than leave this untested time-bomb in place, rip it out.
Hopefully, as originally envisioned, we can find an opportunity
to test an actual sandboxed guest where the guest-agent has
full permissions and will not unduly affect the host running
the test - if so, 'git revert' can be used if desired, for
salvaging any useful parts of this attempt.

ppc/kvm: use kvm_vm_check_extension() in kvmppc_is_pr()
If the host has both KVM PR and KVM HV loaded and we pass:
-machine pseries,accel=kvm,kvm-type=PR
the kvmppc_is_pr() returns false instead of true. Since the helper
is mostly used as fallback, it doesn't have any real impact with
recent kernels. A notable exception is the workaround to allow
migration between compatible hosts with different PVRs (eg, POWER8
and POWER8E), since KVM still doesn't provide a way to check if a
specific PVR is supported (see commit
c363a37a450f for details).
According to the official KVM API documentation [1], KVM_PPC_GET_PVINFO
is "vm ioctl", but we check it as a global ioctl. The following function
in KVM is hence called with kvm == NULL and considers we're in HV mode.
int kvm_vm_ioctl_check_extension(struct kvm *kvm, long ext)
{
int r;
/* Assume we're using HV mode when the HV module is loaded */
int hv_enabled = kvmppc_hv_ops ? 1 : 0;
if (kvm) {
/*
* Hooray - we know which VM type we're running on. Depend on
* that rather than the guess above.
*/
hv_enabled = is_kvmppc_hv_enabled(kvm);
}

spapr_pci: don't create 64-bit MMIO window if we don't need to

The same thing occurs when running a pseries-2.7 with
-global spapr-pci-host-bridge.mem_win_size=
2147483648
This happens because we always create a 64-bit MMIO window, even if
we didn't explicitely requested it (ie, mem64_win_size == 0) and the
32-bit window is below 2GiB. It doesn't seem to have an impact on the
guest though because spapr_populate_pci_dt() doesn't advertise the
bogus windows when mem64_win_size == 0.
Since these memory regions don't induce any state, we can safely
choose to not create them when their address is equal to -1,
without breaking migration from existing setups.

spapr: fix CAS-generated reset
The OV5_MMU_RADIX_300 requires special handling in the CAS negotiation
process. It is cleared from the option vector of the guest before
evaluating the changes and re-added later. But, when testing for a
possible CAS reset :
spapr->cas_reboot = spapr_ovec_diff(ov5_updates,
ov5_cas_old, spapr->ov5_cas);
the bit OV5_MMU_RADIX_300 will each time be seen as removed from the
previous OV5 set, hence generating a reset loop.
Fix this problem by also clearing the same bit in the ov5_cas_old set.

ppc/xive: fix OV5_XIVE_EXPLOIT bits
On POWER9, the Client Architecture Support (CAS) negotiation process
determines whether the guest operates in XIVE Legacy compatibility or
in XIVE exploitation mode. Now that we have initial guest support for
the XIVE interrupt controller, let's fix the bits definition which have
evolved in the latest specs.
The platform advertises the XIVE Exploitation Mode support using the
property "ibm,arch-vec-5-platform-support-vec-5", byte 23 bits 0-1 :
- 0b00 XIVE legacy mode Only
- 0b01 XIVE exploitation mode Only
- 0b10 XIVE legacy or exploitation mode

spapr: only update SDR1 once per-cpu during CAS
Commit
b55d295e3ec9 added the possibility to support HPT resizing with KVM.
In the case of PR, we need to pass the userspace address of the HPT to KVM
using the SDR1 slot.
This is handled by kvmppc_update_sdr1() which uses CPU_FOREACH() to update
all CPUs. It is hence not needed to call kvmppc_update_sdr1() for each CPU.

hw/ppc/spapr.c: cleaning up qdev_get_machine() calls
This patch removes the qdev_get_machine() calls that are made in
spapr.c in situations where we can get an existing pointer for
the MachineState by either passing it as an argument to the function
or by using other already available pointers.
The following changes were made:
- spapr_node0_size: static function that is called two times:
at spapr_setup_hpt_and_vrma and ppc_spapr_init. In both cases we can
pass an existing MachineState pointer to it.
- spapr_build_fdt: MachineState pointer can be retrieved from
the existing sPAPRMachineState pointer.
- spapr_boot_set: the opaque in the first arg is a sPAPRMachineState
pointer as we can see inside ppc_spapr_init:
qemu_register_boot_set(spapr_boot_set, spapr);
We can get a MachineState pointer from it.
- spapr_machine_device_plug and spapr_machine_device_unplug_request: the
MachineState, sPAPRMachineState, MachineClass and sPAPRMachineClass pointers
can all be retrieved from the HotplugHandler pointer.

net: Add SunGEM device emulation as found on Apple UniNorth
This adds a simplistic emulation of the Sun GEM ethernet controller
found in Apple ASICs.
Currently we only support the Apple UniNorth 1.x variant, but the
other Apple or Sun variants should mostly be a matter of adding
PCI IDs options.
We have a very primitive emulation of a single Broadcom 5201 PHY
which is supported by the MacOS driver.
This model brings out-of-the-box networking to MacOS 9, and all
versions of OS X I tried with the mac99 platform.
Further improvements from Mark:
- Remove sungem.h file, moving constants into sungem.c as required
- Switch to using tracepoints for debugging
- Split register blocks into separate memory regions
- Use arrays in SunGEMState to hold register values
- Add state-saving support
