7c9140afd5 nvic: Handle ARMv6-M SCS reserved registers
Handle SCS reserved registers listed in ARMv6-M ARM D3.6.1.
All reserved registers are RAZ/WI. ARM_FEATURE_M_MAIN is used for the
checks, because these registers are reserved in ARMv8-M Baseline too.

93f874fe9d virtio-gpu: fix crashes upon warm reboot with vga mode
With vga=775 on the Linux command line a first boot of the VM running
Linux works fine. After a warm reboot it crashes during Linux boot.

Before that, valgrind points out bad memory write to console
surface. The VGA code is not aware that virtio-gpu got a message
surface scanout when the display is disabled. Let's reset VGA graphic
mode when it is the case, so that a new display surface is created
when doing further VGA operations.

341823c172 hw/intc/arm_gicv3_common: Move gicd shift bug handling to gicv3_post_load
The code currently in gicv3_gicd_no_migration_shift_bug_post_load()
that handles migration from older QEMU versions with a particular
bug is misplaced. We need to run this after migration in all cases,
not just the cases where the "arm_gicv3/gicd_no_migration_shift_bug"
subsection is present, so it must go in a post_load hook for the
top level VMSD, not for the subsection. Move it.

326049cc8e hw/intc/arm_gicv3_common: Move post_load hooks to top-level VMSD
Contrary to the the impression given in docs/devel/migration.rst,
the migration code does not run the pre_load hook for a
subsection unless the subsection appears on the wire, and so
this is not a place where you can set the default value for
state for the "subsection not present" case. Instead this needs
to be done in a pre_load hook for whatever is the parent VMSD
of the subsection.

We got this wrong in two of the subsection definitions in
the GICv3 migration structs; fix this.

adc4fda6d5 hw/intc/arm_gicv3_common: Combine duplicate .subsections in vmstate_gicv3_cpu
Commit 6692aac411 accidentally introduced a second initialization
of the .subsections field of vmstate_gicv3_cpu, instead of adding
the new subsection to the existing list. The effect of this was
probably that migration of GICv3 with virtualization enabled was
broken (or alternatively that migration of ICC_SRE_EL1 was broken,
depending on which of the two initializers the compiler used).
Combine the two into a single list.

10efd7e108 pc: acpi: fix memory hotplug regression by reducing stub SRAT entry size
Commit 848a1cc1e (hw/acpi-build: build SRAT memory affinity structures for DIMM devices)
broke the first dimm hotplug in following cases:

 1: there is no coldplugged dimm in the last numa node
    but there is a coldplugged dimm in another node

  -m 4096,slots=4,maxmem=32G               \
  -object memory-backend-ram,id=m0,size=2G \
  -device pc-dimm,memdev=m0,node=0         \
  -numa node,nodeid=0                      \
  -numa node,nodeid=1

 2: if order of dimms on CLI is:
       1st plugged dimm in node1
       2nd plugged dimm in node0

  -m 4096,slots=4,maxmem=32G               \
  -object memory-backend-ram,size=2G,id=m0 \
  -device pc-dimm,memdev=m0,node=1         \
  -object memory-backend-ram,id=m1,size=2G \
  -device pc-dimm,memdev=m1,node=0         \
  -numa node,nodeid=0                      \
  -numa node,nodeid=1

(qemu) object_add memory-backend-ram,id=m2,size=1G
(qemu) device_add pc-dimm,memdev=m2,node=0

the first DIMM hotplug to any node except the last one
fails (Windows is unable to online it).

Length reduction of stub hotplug memory SRAT entry,
fixes issue for some reason.

6484ab3dff sam460ex: Fix PCI interrupts with multiple devices
The four interrupts of the PCI bus are connected to the same UIC pin
on the real Sam460ex. Evidence for this can be found in the UBoot
source for the Sam460ex in the Sam460ex.c file where
PCI_INTERRUPT_LINE is written. Change the ppc440_pcix model to behave
more like this.

This fixes the problem that can be observed when adding further PCI
cards that got their interrupt rotated to other interrupts than PCI
INT A. In particular, the bug was observed with an additional OHCI PCI
card or an ES1370 sound device.

not do the same for maxram_size, which means for large guests
with some sizes (e.g. -m 50000) maxram_size differs from ram_size.
This can break other code (e.g. CMMA migration) which uses maxram_size
to calculate the number of pages and then throws some errors.

218fe5ce40 hw/misc/tz-mpc: Zero the LUT on initialization, not just reset

which we then clear to zero in the device's reset method.
This is conceptually fine, but unfortunately results in a

==30906==    by 0x7B1775: qemu_devices_reset (reset.c:69)

This is because of a reset ordering problem -- the TZ MPC
resets after the CPU, but an M-profile CPU's reset function
includes memory loads to get the initial PC and SP, which
then go through an MPC that hasn't yet been reset.

The simplest fix for this is to zero the LUT when we
initialize the data, which will result in the MPC's
translate function giving the right answers for these
early memory accesses.

Hence if two or more optional properties are missing, an assertion is
triggered:

    util/error.c:57: error_setv: Assertion `*errp == NULL' failed.

Fis this by resetting err to NULL after ignoring the error.

1a5182c0d2 target/arm: Escalate to correct HardFault when AIRCR.BFHFNMINS is set
When we escalate a v8M exception to HardFault, if AIRCR.BFHFNMINNS is
set then we need to decide whether it should become a secure HardFault
or a nonsecure HardFault. We should always escalate to the same
target security state as the original exception. The current code
tries to test this using the 'secure' bool, which is not right because
that flag indicates whether the target security state only for
banked exceptions; the effect was that we were incorrectly escalating
always-secure exceptions like SecureFault to a nonsecure HardFault.

Fix this by defining, logging and using a new 'targets_secure' bool
which tracks the condition we actually want.

1ddc9b98c3 hw/intc/exynos4210_gic: Turn instance_init into realize function
The instance_init function of the "exynos4210.gic" device creates a
new "arm_gic" device and immediately realizes it with qdev_init_nofail().
This will leave a lot of object in the QOM tree during introspection of
the "exynos4210.gic" device, e.g. reproducible by starting QEMU like this:

qemu-system-aarch64 -M none -nodefaults -nographic -monitor stdio

And then by running "info qom-tree" at the HMP monitor, followed by
"device_add exynos4210.gic,help" and finally checking "info qom-tree"
again.

Also note that qdev_init_nofail() can exit QEMU in case of errors - and
this must never happen during an instance_init function, otherwise QEMU
could terminate unexpectedly during introspection of a device.

Since most of the code that follows the qdev_init_nofail() depends on
the realized "gicbusdev", the easiest solution to the problem is to
turn the whole instance_init function into a realize function instead.

07bc425ea3 hw/arm/spitz: Move problematic nand_init() code to realize function
nand_init() does not only create the NAND device, it also realizes
the device with qdev_init_nofail() already. So we must not call
nand_init() from an instance_init function like sl_nand_init(),
otherwise we get superfluous NAND devices in the QOM tree after
introspecting the 'sl-nand' device. So move the nand_init() to the
realize function of 'sl-nand' instead.

- A block interrupt must be generated after each block to indicate

Rearrange the code to make this happen. Tested on raspi3 (in PIO mode)

f8da93a0ff i386: only parse the initrd_filename once for multiboot modules
The multiboot code parses the initrd_filename twice, first to count how
many entries there are, and second to process each entry. This changes
the first loop to store the parse module names in a list, and the second
loop can now use these names. This avoids having to pass NULL to the
get_opt_value() method which means it can safely assume a non-NULL param.

fe04f0b4a1 hw/display/xlnx_dp: Move problematic code from instance_init to realize
aux_create_slave() calls qdev_init_nofail() which in turn "realizes"
the corresponding object. This is unlike qdev_create(), and it is wrong
because qdev_init_nofail() must not be called from an instance_init
function.  Move qdev_init_nofail() and the subsequent aux_map_slave into
the caller's realize function.

There are two more bugs that needs to be fixed here, too, where the
objects are created but not added as children.  Therefore when
you call object_unparent on them, nothing happens.

In particular dpcd and edid give you an infinite loop in bus_unparent,
because device_unparent is not called and does not remove them from
the list of devices on the bus.

955cbc6b17 hw/arm/armv7: Fix crash when introspecting the "iotkit" device
QEMU currently crashes when introspecting the "iotkit" device and
runnint "info qtree" afterwards, e.g. when running QEMU like this:

echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \

 "'arguments': {'command-line': 'info qtree'}}" | \

Use the new functions object_initialize_child() and sysbus_init_child_obj()
to make sure that all objects get cleaned up correctly when the instances
are destroyed.
