38e2a77c9d target/arm: Define init-svtor property for the reset secure VTOR value
The Cortex-M33 allows the system to specify the reset value of the
secure Vector Table Offset Register (VTOR) by asserting config
signals. In particular, guest images for the MPS2 AN505 board rely
on the MPS2's initial VTOR being correct for that board.
Implement a QEMU property so board and SoC code can set the reset
value to the correct value.

181962fd69 target/arm: Define an IDAU interface
In v8M, the Implementation Defined Attribution Unit (IDAU) is
a small piece of hardware typically implemented in the SoC
which provides board or SoC specific security attribution
information for each address that the CPU performs MPU/SAU
checks on. For QEMU, we model this with a QOM interface which
is implemented by the board or SoC object and connected to
the CPU using a link property.

This commit defines the new interface class, adds the link
property to the CPU object, and makes the SAU checking
code call the IDAU interface if one is present.

be8b49de24 s390x/tcg: fix loading 31bit PSWs with the highest bit set
Let's also put the 31-bit hack in front of the REAL MMU, otherwise right
now we get errors when loading a PSW where the highest bit is set (e.g.
via s390-netboot.img). The highest bit is not masked away, therefore we
inject addressing exceptions into the guest.

The proper fix will later be to do all address wrapping before accessing
the MMU - so we won't get any "wrong" entries in there (which makes
flushing also easier). But that will require more work (wrapping in
load_psw, wrapping when incrementing the PC, wrapping every memory
access).

This fixes the tests/pxe-test test.

d719cbc764 arm/helper.c: re-factor rsqrte and add rsqrte_f16
Much like recpe the ARM ARM has simplified the pseudo code for the
calculation which is done on a fixed point 9 bit integer maths. So
while adding f16 we can also clean this up to be a little less heavy
on the floating point and just return the fractional part and leave
the calle's to do the final packing of the result.

82fab5c5b9 s390x/sclp: remove memory hotplug support
From an architecture point of view, nothing can be mapped into the address
space on s390x. All there is is memory. Therefore there is also not really
an interface to communicate such information to the guest. All we can do is
specify the maximum ram address and guests can probe in that range if
memory is available and usable (TPROT).

Also memory hotplug is strange. The guest can decide at some point in
time to add / remove memory in some range. While the hypervisor can deny
to online an increment, all increments have to be predefined and there is
no way of telling the guest about a newly "hotplugged" increment. So if we
specify right now e.g.
    -m 2G,slots=2,maxmem=20G
An ordinary fedora guest will happily online (hotplug) all memory,
resulting in a guest consuming 20G. So it really behaves rather like
    -m 22G
There is no way to hotplug memory from the outside like on other
architectures. This is of course bad for upper management layers.

As the guest can create/delete memory regions while it is running, of
course migration support is not available and tricky to implement.

With virtualization, it is different. We might want to map something
into guest address space (e.g. fake DAX devices) and not detect it
automatically as memory. So we really want to use the maxmem and slots
parameter just like on all other architectures. Such devices will have
to expose the applicable memory range themselves. To finally be able to
provide memory hotplug to guests, we will need a new paravirtualized
interface to do that (e.g. something into the direction of virtio-mem).

This implies, that maxmem cannot be used for s390x memory hotplug
anymore and has to go. This simplifies the code quite a bit.

As migration support is not working, this change cannot really break
migration as guests without slots and maxmem don't see the SCLP
features. Also, the ram size calculation does not change.

a5a2b80d95 s390x/cpumodel: document S390FeatDef.bit not applicable
The 'bit' field of the 'S390FeatDef' structure is not applicable to all
its instances. Currently this field is not applicable, and remains
unused, iff the feature is of type S390_FEAT_TYPE_MISC. Having the value 0
specified for multiple such feature definitions was a little confusing,
as it's a perfectly legit bit value, and as the value of the bit
field is usually ought to be unique for each feature of a given
feature type.

Let us introduce a specialized macro for defining features of type
S390_FEAT_TYPE_MISC so, that one does not have to specify neither bit nor
type (as the latter is implied).

9d0306dfdf qmp: expose s390-specific CPU info
Presently s390x is the only architecture not exposing specific
CPU information via QMP query-cpus. Upstream discussion has shown
that it could make sense to report the architecture specific CPU
state, e.g. to detect that a CPU has been stopped.

With this change the output of query-cpus will look like this on
s390:

   [
     {"arch": "s390", "current": true,
      "props": {"core-id": 0}, "cpu-state": "operating", "CPU": 0,
      "qom_path": "/machine/unattached/device[0]",
      "halted": false, "thread_id": 63115},
     {"arch": "s390", "current": false,
      "props": {"core-id": 1}, "cpu-state": "stopped", "CPU": 1,
      "qom_path": "/machine/unattached/device[1]",
      "halted": true, "thread_id": 63116}
   ]

This change doesn't add the s390-specific data to HMP 'info cpus'.
A follow-on patch will remove all architecture specific information
from there.

4ada99ade2 s390x/cpu: expose the guest crash information
This patch is the s390 implementation of guest crash information,
similar to commit d187e08dc4 ("i386/cpu: add crash-information QOM
property") and the related commits. We will detect several crash
reasons, with the "disabled wait" being the most important one, since
this is used by all s390 guests as a "panic like" notification.

Demonstrate these ways with examples as follows.

  1. crash-information QOM property;

  Run qemu with -qmp unix:qmp-sock,server, then use utility "qmp-shell"
  to execute "qom-get" command, and might get the result like,

  (QEMU) (QEMU) qom-get path=/machine/unattached/device[0] \
      property=crash-information
  {"return": {"core": 0, "reason": "disabled-wait", "psw-mask": 562956395872256, \
      "type": "s390", "psw-addr": 1102832}}

  2. GUEST_PANICKED event reporting;

  Run qemu with a socket option, and telnet or nc to that,
  -chardev socket,id=qmp,port=4444,host=localhost,server \
  -mon chardev=qmp,mode=control,pretty=on \
  Negotiating the mode by { "execute": "qmp_capabilities" }, and the crash
  information will be reported on a guest crash event like,

  {
    "timestamp": {
        "seconds": 1518004739,
        "microseconds": 552563
    },
    "event": "GUEST_PANICKED",
    "data": {
        "action": "pause",
        "info": {
            "core": 0,
            "psw-addr": 1102832,
            "reason": "disabled-wait",
            "psw-mask": 562956395872256,
            "type": "s390"
        }
    }

36476562d5 target/arm: Fix register definitions for VMIDR and VMPIDR
The register definitions for VMIDR and VMPIDR have separate
reginfo structs for the AArch32 and AArch64 registers. However
the 32-bit versions are wrong:
 * they use offsetof instead of offsetoflow32 to mark where
   the 32-bit value lives in the uint64_t CPU state field
 * they don't mark themselves as ARM_CP_ALIAS

In particular this means that if you try to use an Arm guest CPU
which enables EL2 on a big-endian host it will assert at reset:
 target/arm/cpu.c:114: cp_reg_check_reset: Assertion `oldvalue == newvalue' failed.

because the reset of the 32-bit register writes to the top
half of the uint64_t.

Correct the errors in the structures.

This is necessary for 'make check' to pass on big endian
systems with the 'raspi3' board enabled, which is the
first board which has an EL2-enabled-by-default CPU.

24f91e81b6 target/*/cpu.h: remove softfloat.h
As cpu.h is another typically widely included file which doesn't need
full access to the softfloat API we can remove the includes from here
as well. Where they do need types it's typically for float_status and
the rounding modes so we move that to softfloat-types.h as well.

As a result of not having softfloat in every cpu.h call we now need to
add it to various helpers that do need the full softfloat.h
definitions.

06329ccecf mem: add share parameter to memory-backend-ram
Currently only file backed memory backend can
be created with a "share" flag in order to allow
sharing guest RAM with other processes in the host.

Add the "share" flag also to RAM Memory Backend
in order to allow remapping parts of the guest RAM
to different host virtual addresses. This is needed
by the RDMA devices in order to remap non-contiguous
QEMU virtual addresses to a contiguous virtual address range.

Moved the "share" flag to the Host Memory base class,
modified phys_mem_alloc to include the new parameter
and a new interface memory_region_init_ram_shared_nomigrate.

There are no functional changes if the new flag is not used.

e1e7cbc904 target/arm: Migrate v7m.other_sp

no-longer-used v7m.current_sp flag from the VMState but also
deleted the still very much in use v7m.other_sp SP value field.)

Add a subsection to migrate it again. (We don't need to care

43bbce7fbe hw/intc/armv7m_nvic: Implement cache ID registers
M profile cores have a similar setup for cache ID registers
to A profile:
 * Cache Level ID Register (CLIDR) is a fixed value
 * Cache Type Register (CTR) is a fixed value
 * Cache Size ID Registers (CCSIDR) are a bank of registers;
   which one you see is selected by the Cache Size Selection
   Register (CSSELR)

The only difference is that they're in the NVIC memory mapped
register space rather than being coprocessor registers.
Implement the M profile view of them.

Since neither Cortex-M3 nor Cortex-M4 implement caches,
we don't need to update their init functions and can leave
the ctr/clidr/ccsidr[] fields in their ARMCPU structs at zero.
Newer cores (like the Cortex-M33) will want to be able to
set these ID registers to non-zero values, though.

7a5235c9e6 hax: Support guest RAM sizes of 4GB or more
Since HAX_VM_IOCTL_ALLOC_RAM takes a 32-bit size, it cannot handle
RAM blocks of 4GB or larger, which is why HAXM can only run guests
with less than 4GB of RAM. Solve this problem by utilizing the new
HAXM API, HAX_VM_IOCTL_ADD_RAMBLOCK, which takes a 64-bit size, to
register RAM blocks with the HAXM kernel module. The new API is
first added in HAXM 7.0.0, and its availablility and be confirmed
by the presence of the HAX_CAP_64BIT_RAMBLOCK capability flag.

When the guest RAM size reaches 7GB, QEMU will ask HAXM to set up a
memory mapping that covers a 4GB region, which will fail, because
HAX_VM_IOCTL_SET_RAM also takes a 32-bit size. Work around this
limitation by splitting the large mapping into small ones and
calling HAX_VM_IOCTL_SET_RAM multiple times.

<malloc.h> is a non-standard header; it is not obsolete (we must
use it for malloc_trim, for example), but generally should not
be used in files that just need malloc() and friends, where
<stdlib.h> is the standard header.

And since osdep.h already guarantees string.h and stdlib.h, we
can drop these unusual system header includes as redundant
rather than replacing them.

452fcdbc49 Include qapi/qmp/qdict.h exactly where needed
This cleanup makes the number of objects depending on qapi/qmp/qdict.h
drop from 4550 (out of 4743) to 368 in my "build everything" tree.
For qapi/qmp/qobject.h, the number drops from 4552 to 390.

While there, separate #include from file comment with a blank line.

15280c360e qdict qlist: Make most helper macros functions
The macro expansions of qdict_put_TYPE() and qlist_append_TYPE() need
qbool.h, qnull.h, qnum.h and qstring.h to compile.  We include qnull.h
and qnum.h in the headers, but not qbool.h and qstring.h.  Works,
because we include those wherever the macros get used.

Open-coding these helpers is of dubious value.  Turn them into
functions and drop the includes from the headers.

This cleanup makes the number of objects depending on qapi/qmp/qnum.h
from 4551 (out of 4743) to 46 in my "build everything" tree.  For
qapi/qmp/qnull.h, the number drops from 4552 to 21.

6b67395762 Eliminate qapi/qmp/types.h
qapi/qmp/types.h is a convenience header to include a number of
qapi/qmp/ headers.  Since we rarely need all of the headers
qapi/qmp/types.h includes, we bypass it most of the time.  Most of the
places that use it don't need all the headers, either.

Include the necessary headers directly, and drop qapi/qmp/types.h.

384c6c03fb target/arm/translate.c: Fix missing 'break' for TT insns
The code where we added the TT instruction was accidentally
missing a 'break', which meant that after generating the code
to execute the TT we would fall through to 'goto illegal_op'
and generate code to take an UNDEF insn.

bd55947884 target/arm/kvm: gic: Prevent creating userspace GICv3 with KVM
KVM doesn't support emulating a GICv3 in userspace, only GICv2.  We
currently attempt this anyway, and as a result a KVM guest doesn't
receive interrupts and the user is left wondering why.  Report an error
to the user if this particular combination is requested.
