This test was written/tested around beginning of 2019, but was
extracted from a bigger series and posted end of June 2019 [*].
Unfortunately I did not notice commit 162abf1a8 was merged by
then, which implements the AHB and APB plug and play devices.
HelenOS 0.6 is expecting the PnP registers to be not implemented
by QEMU, then forces the discovered AMBA devices (see [2]).
Before 162abf1a8, the console was displaying:

In write_elf_section() we set the 'shdr' pointer to point to local
structures shdr32 or shdr64, which we fill in to be written out to
the ELF dump. Unfortunately the address we pass to fd_write_vmcore()
has a spurious '&' operator, so instead of writing out the section
header we write out the literal pointer value followed by whatever is
on the stack after the 'shdr' local variable.
Pass the correct address into fd_write_vmcore().

Remove a direct include of assert.h -- this is already
provided by qemu/osdep.h, and it breaks our rule that the
first include must always be osdep.h.
In particular we must get the assert() macro via osdep.h
to avoid compile failures on mingw (see the comment in
osdep.h where we redefine assert() for that platform).

An old comment in get_phys_addr_lpae() claims that the code does not
support the different format TCR for VTCR_EL2. This used to be true
but it is not true now (in particular the aa64_va_parameters() and
aa32_va_parameters() functions correctly handle the different
register format by checking whether the mmu_idx is Stage2).

Our implementation of the PSTATE.PAN bit incorrectly cleared all
access permission bits for privileged access to memory which is
user-accessible. It should only affect the privileged read and write
permissions; execute permission is dealt with via XN/PXN instead.

Coverity complains that the collie_init() function leaks the memory
allocated in sa1110_init(). This is true but not significant since
the function is called only once on machine init and the memory must
remain in existence until QEMU exits anyway.
Still, we can avoid the technical memory leak by keeping the pointer
to the StrongARMState inside the machine state struct. Switch from
the simple DEFINE_MACHINE() style to defining a subclass of
TYPE_MACHINE which extends the MachineState struct, and keep the
pointer there.

When a file descriptor becomes ready we must re-arm POLL_ADD. This is
done by adding an sqe to the io_uring sq ring. The ->need_wait()
function wasn't taking pending sqes into account and therefore
io_uring_submit_and_wait() was not being called. Polling for cqes
failed to detect fd readiness since we hadn't submitted the sqe to
io_uring.
This patch fixes the following tests/test-aio -p /aio/event/wait
failure:
ok 11 /aio/event/wait

Since bd457782b3b0 ("x86/pc: use memdev for RAM") Xen
machine fails to start with:
qemu-system-i386: xen: failed to populate ram at 0
The reason is that xen_ram_alloc() which is called by
memory_region_init_ram(), compares memory region with
statically allocated 'global' ram_memory memory region
that it uses for RAM, and does nothing in case it matches.
While it's possible feed machine->ram to xen_ram_alloc()
in the same manner to keep that hack working, I'd prefer
not to keep that circular dependency and try to untangle that.
However it doesn't look trivial to fix, so as temporary
fixup opt out Xen machine from memdev based RAM allocation,
and let xen_ram_alloc() do its trick for now.

Commit 048c95163b4 ("target/i386: work around KVM_GET_MSRS bug for
secondary execution controls") added a workaround for KVM pre-dating
commit 6defc591846d ("KVM: nVMX: include conditional controls in /dev/kvm
KVM_GET_MSRS") which wasn't setting certain available controls. The
workaround uses generic CPUID feature bits to set missing VMX controls.
It was found that in some cases it is possible to observe hosts which
have certain CPUID features but lack the corresponding VMX control.
In particular, it was reported that Azure VMs have RDSEED but lack
VMX_SECONDARY_EXEC_RDSEED_EXITING; attempts to enable this feature
bit result in QEMU abort.
Resolve the issue but not applying the workaround when we don't have
to. As there is no good way to find out if KVM has the fix itself, use
95c5c7c77c ("KVM: nVMX: list VMX MSRs in KVM_GET_MSR_INDEX_LIST") instead
as these [are supposed to] come together.

After c9808d60281 we have both an object representing the serial-isa
device and a separate object representing the underlying common serial
uart. Both of these have vmsd's associated with them and thus the
migration stream ends up with two copies of the migration data - the
serial-isa includes the vmstate of the core serial. Besides
being wrong, it breaks backwards migration compatibility.
Fix this by removing the dc->vmsd from the core device, so it only
gets migrated by any parent devices including it.
Add a vmstate_serial_mm so that any device that uses serial_mm_init
rather than creating a device still gets migrated.
(That doesn't fix backwards migration for serial_mm_init users,
but does seem to work forwards for ppce500).
Fixes: c9808d60281 ('serial: realize the serial device')

The sequence of instructions exposes an issue:
sti
hlt
Interrupts cannot be delivered to hvf after hlt instruction cpu because
HF_INHIBIT_IRQ_MASK is set just before hlt is handled and never reset
after moving instruction pointer beyond hlt.
So, after hvf_vcpu_exec() returns, CPU thread gets locked up forever in
qemu_wait_io_event() (cpu_thread_is_idle() evaluates inhibition
flag and considers the CPU idle if the flag is set).

Commit a1b18df9a4848, broke virt_kvm_type() logic, which depends on
maxram_size, ram_size, ram_slots being parsed/set on machine instance
at the time accelerator (KVM) is initialized.
set_memory_options() part was already reverted by commit 2a7b18a3205b,
so revert remaining initialization of above machine fields to make
virt_kvm_type() work as it used to.

Older QEMU versions did fixup the ram size to match what can be reported
via sclp. We need to mimic this behaviour for machine types 4.2 and
older to not fail on inbound migration for memory sizes that do not fit.
Old machines with proper aligned memory sizes are not affected.
Alignment table:
VM size (<=) | Alignment
--------------------------
1020M | 1M
2040M | 2M
4080M | 4M
8160M | 8M
16320M | 16M
32640M | 32M
65280M | 64M
130560M | 128M
261120M | 256M
522240M | 512M
1044480M | 1G
2088960M | 2G
4177920M | 4G
8355840M | 8G
Suggested action is to replace unaligned -m value with a suitable
aligned one or if a change to a newer machine type is possible, use a
machine version >= 5.0.
A future version might remove the compatibility handling.
For machine types >= 5.0 we can simply use an increment size of 1M and
use the full range of increment number which allows for all possible
memory sizes. The old limitation of having a maximum of 1020 increments
was added for standby memory, which we no longer support. With that we
can now support even weird memory sizes like 10001234 MB.
As we no longer fixup maxram_size as well, make other users use ram_size
instead. Keep using maxram_size when setting the maximum ram size in KVM,
as that will come in handy in the future when supporting memory hotplug
(in contrast, storage keys and storage attributes for hotplugged memory
will have to be migrated per RAM block in the future).

The cpu number reporting is handled by KVM and QEMU only fills in the
VM name, uuid and other values.
Unfortunately KVM doesn't report reserved cpus and doesn't even know
they exist until the are created via the ioctl.
So let's fix up the cpu values after KVM has written its values to the
3.2.2 sysib. To be consistent, we use the same code to retrieve the cpu
numbers as the STSI TCG code in target/s390x/misc_helper.c:HELPER(stsi).

When running Ubuntu 3.13.0-65-generic guest, QEMU sometimes crashes
during guest ACPI reset. It crashes on assert(s->rings_info_valid)
in pvscsi_process_io().
Analyzing the crash revealed that it happens when userspace issues
a sync during a reboot syscall.
Below are backtraces we gathered from the guests.
Guest backtrace when issuing PVSCSI_CMD_ADAPTER_RESET:
pci_device_shutdown
device_shutdown
init_pid_ns
init_pid_ns
kernel_power_off
SYSC_reboot
Guest backtrace when issuing PVSCSI_REG_OFFSET_KICK_RW_IO:
scsi_done

Since QEMU pvscsi should imitate VMware pvscsi device emulation,
we decided to imitate VMware's behavior in this case.
To check VMware behavior, we wrote a kernel module that issues
a reset to the pvscsi device and then issues a kick. We ran it on
VMware ESXi 6.5 and it seems that it simply ignores the kick.
Hence, we decided to ignore the kick as well.

The APIC ID is decoded based on the sequence sockets->dies->cores->threads.
This works fine for most standard AMD and other vendors' configurations,
but this decoding sequence does not follow that of AMD's APIC ID enumeration
strictly. In some cases this can cause CPU topology inconsistency.
When booting a guest VM, the kernel tries to validate the topology, and finds
it inconsistent with the enumeration of EPYC cpu models. The more details are
in the bug https://bugzilla.redhat.com/show_bug.cgi?id=1728166.
To fix the problem we need to build the topology as per the Processor
Programming Reference (PPR) for AMD Family 17h Model 01h, Revision B1
Processors. The documentation is available from the bugzilla Link below.
Link: https://bugzilla.kernel.org/show_bug.cgi?id=206537
It is also available at
https://www.amd.com/system/files/TechDocs/55570-B1_PUB.zip
Here is the text from the PPR.
Operating systems are expected to use Core::X86::Cpuid::SizeId[ApicIdSize], the
number of least significant bits in the Initial APIC ID that indicate core ID
within a processor, in constructing per-core CPUID masks.
Core::X86::Cpuid::SizeId[ApicIdSize] determines the maximum number of cores
(MNC) that the processor could theoretically support, not the actual number of
cores that are actually implemented or enabled on the processor, as indicated
by Core::X86::Cpuid::SizeId[NC].
Each Core::X86::Apic::ApicId[ApicId] register is preset as follows:
• ApicId[6] = Socket ID.
• ApicId[5:4] = Node ID.
• ApicId[3] = Logical CCX L3 complex ID
• ApicId[2:0]= (SMT) ? {LogicalCoreID[1:0],ThreadId} : {1'b0,LogicalCoreID[1:0]}
The new apic id encoding is enabled for EPYC and EPYC-Rome models.

Apicid calculation depends on knowing the total number of numa nodes
for EPYC cpu models. Right now, we are calculating the arch_id while
parsing the numa(parse_numa). At this time, it is not known how many
total numa nodes are configured in the system.
Move the arch_id calculation inside x86_cpus_init. At this time, smp
parse is already completed and numa node information is available.

Also replace the calling convention to use handlers from
