if KVM is enabled and KVM capabilities MMU radix is available,
the partition table entry (patb_entry) for the radix mode is
initialized by default in ppc_spapr_reset().
It's a problem if we want to migrate the guest to a POWER8 host
while the kernel is not started to set the value to the one
expected for a POWER8 CPU.
The "-machine max-cpu-compat=power8" should allow to migrate
a POWER9 KVM host to a POWER8 KVM host, but because patb_entry
is set, the destination QEMU tries to enable radix mode on the
POWER8 host. This fails and cancels the migration:
Process table config unsupported by the host
error while loading state for instance 0x0 of device 'spapr'
load of migration failed: Invalid argument
This patch doesn't set the PATB entry if the user provides
a CPU compatibility mode that doesn't support radix mode.

We conditionally adjust part of the guest device tree based on the

Machine objects have two init functions - the generic QOM level
instance_init which should only do static object initialization, and
the Machine specific MachineClass::init which does the actual
construction of the machine.
In spapr the functions implementing these two have names -
ppc_machine_initfn() and ppc_spapr_init() - which don't correspond closely
to either of those. To prevent people (read, me) from confusing which is
which, rename them spapr_instance_init() and spapr_machine_init() to
make it clearer which is which.
While we're there rename ppc_spapr_reset() to spapr_machine_reset() to
match.

According to LoPAPR 1.1 B.6.12, the "/event-sources" node has an "interrupt-
ranges" property, the format of which is described in B.6.9.1.2 as follows:
“interrupt-ranges”
Standard property name that defines the interrupt number(s) and range(s)
handled by this unit.
prop-encoded-array: List of (int-number, range) specifications.
Int-number is encoded as with encode-int.
Range is encoded as with encode-int.
The first entry in this list shall contain the int-number associated with
the first “reg” property entry. The int-num-ber is the value representing
the interrupt source as would appear in the PowerPC External Interrupt
Architecture XISR. The range shall be the number of sequential interrupt
numbers which this unit can generate.
There's no such thing as a cell count at the end of the array, like the
one introduced by commit ffbb1705a33d in QEMU 2.8. It doesn't seem it had
any impact on existing guests and I couldn't find any related workaround
in linux. So, let's just drop the bogus lines.

LoPAPR 1.1 B.6.9.1.2 describes the "#interrupt-cells" property of the
PowerPC External Interrupt Source Controller node as follows:
“#interrupt-cells”
Standard property name to define the number of cells in an interrupt-
specifier within an interrupt domain.
prop-encoded-array: An integer, encoded as with encode-int, that denotes
the number of cells required to represent an interrupt specifier in its
child nodes.
The value of this property for the PowerPC External Interrupt option shall
be 2. Thus all interrupt specifiers (as used in the standard “interrupts”
property) shall consist of two cells, each containing an integer encoded
as with encode-int. The first integer represents the interrupt number the
second integer is the trigger code: 0 for edge triggered, 1 for level
triggered.
This patch fixes the interrupt specifiers in the "interrupt-map" property
of the PHB node, that were setting the second cell to 8 (confusion with
IRQ_TYPE_LEVEL_LOW ?) instead of 1.
VIO devices and RTAS event sources use the same format for interrupt
specifiers: while here, we introduce a common helper to handle the
encoding details.

'halted' is switched to 1 and, in this case, the MSR is not taken into
account anymore in the cpu_has_work() routine. Only the pending
hardware interrupts are checked with their LPCR:PECE* enablement bit.

If the DECR timer fires after 'stop-self' is called and before the CPU
'stop' state is reached, the nearly-dead CPU will have some work to do
and the guest will crash. This case happens very frequently with the
not yet upstream P9 XIVE exploitation mode. In XICS mode, the DECR is
occasionally fired but after 'stop' state, so no work is to be done
and the guest survives.
I suspect there is a race between the QEMU mainloop triggering the
timers and the TCG CPU thread but I could not quite identify the root
cause. To be safe, let's disable in the LPCR all the exceptions which
can cause an exit while the CPU is in power-saving mode and reenable

The current code assumes that only the CPU core object holds a
reference on each individual CPU object, and happily frees their
allocated memory when the core is unrealized. This is dangerous
as some other code can legitimely keep a pointer to a CPU if it
calls object_ref(), but it would end up with a dangling pointer.
Let's allocate all CPUs with object_new() and let QOM free them
when their reference count reaches zero. This greatly simplify the
code as we don't have to fiddle with the instance size anymore.

At guest reset time, we allocate a hash page table (HPT) for the guest
based on the guest's RAM size. If dynamic HPT resizing is not available we
use the maximum RAM size, if it is we use the current RAM size.
But the "current RAM size" calculation is incorrect - we just use the
"base" ram_size from the machine structure. This doesn't include any
pluggable DIMMs that are already plugged at reset time.
This means that if you try to start a 'pseries' machine with a DIMM
specified on the command line that's much larger than the "base" RAM size,
then the guest will get a woefully inadequate HPT. This can lead to a
guest freeze during boot as it runs out of HPT space during initial MMU
setup.

The patb_entry is used to store the location of the process table in
guest memory. The msb is also used to indicate the mmu mode of the
guest, that is patb_entry & 1 << 63 ? radix_mode : hash_mode.
Currently we set this to zero in spapr_setup_hpt_and_vrma() since if
this function gets called then we know we're hash. However some code
paths, such as setting up the hpt on incoming migration of a hash guest,
call spapr_reallocate_hpt() directly bypassing this higher level
function. Since we assume radix if the host is capable this results in
the msb in patb_entry being left set so in spapr_post_load() we call
kvmppc_configure_v3_mmu() and tell the host we're radix which as
expected means addresses cannot be translated once we actually run the cpu.
To fix this move the zeroing of patb_entry into spapr_reallocate_hpt().

LUNs >= 256 have to be encoded with the so-called "flat space
addressing method" for virtio-scsi, where an additional bit has to
be set. SLOF already took care of this with the following commit:
https://git.qemu.org/?p=SLOF.git;a=commitdiff;h=f72a37713fea47da
(see https://bugzilla.redhat.com/show_bug.cgi?id=1431584 for details)
But QEMU does not use this encoding yet for device tree paths
that have to be handed over to SLOF to deal with the "bootindex"
property, so SLOF currently fails to boot from virtio-scsi devices
with LUNs >= 256 in the right boot order. Fix it by using the bit
to indicate the "flat space addressing method" for LUNs >= 256.

A DRC with a pending unplug request releases its associated device at
machine reset time.
In the case of LMB, when all DRCs for a DIMM device have been reset,
the DIMM gets unplugged, causing guest memory to disappear. This may
be very confusing for anything still using this memory.
This is exactly what happens with vhost backends, and QEMU aborts
with:
qemu-system-ppc64: used ring relocated for ring 2
qemu-system-ppc64: qemu/hw/virtio/vhost.c:649: vhost_commit: Assertion
`r >= 0' failed.
The issue is that each DRC registers a QEMU reset handler, and we
don't control the order in which these handlers are called (ie,
a LMB DRC will unplug a DIMM before the virtio device using the
memory on this DIMM could stop its vhost backend).
To avoid such situations, let's reset DRCs after all devices
have been reset.

The device tree nodes ibm,arch-vec-5-platform-support and ibm,pa-features
are used to communicate features of the cpu to the guest operating
system. The properties of each of these are determined based on the
selected cpu model and the availability of hypervisor features.
Currently the compatibility mode of the cpu is not taken into account.
The ibm,arch-vec-5-platform-support node is used to communicate the
level of support for various ISAv3 processor features to the guest
before CAS to inform the guests' request. The available mmu mode should
only be hash unless the cpu is a POWER9 which is not in a prePOWER9
compat mode, in which case the available modes depend on the
accelerator and the hypervisor capabilities.
The ibm,pa-featues node is used to communicate the level of cpu support
for various features to the guest os. This should only contain features
relevant to the operating mode of the processor, that is the selected
cpu model taking into account any compat mode. This means that the
compat mode should be taken into account when choosing the properties of
ibm,pa-features and they should match the compat mode selected, or the
cpu model selected if no compat mode.
Update the setting of these cpu features in the device tree as described
above to properly take into account any compat mode. We use the
ppc_check_compat function which takes into account the current processor
model and the cpu compat mode.

KVM HV will soon support running a guest in hash mode on a POWER9 host
running in radix mode (see [1]), however the guest currently fails to
boot.
This is because the "htab_shift" value (the size of the MMU's hash
table) is added to the device tree before KVM has had a chance to
change it. If the host is in hash mode, KVM does not need to change it
and so the problem is not seen, but when the host is in radix mode a
change is required and we see a problem.
To fix this, move the call spapr_setup_hpt_and_vrma() (where
htab_shift could be changed) up a little so that it's called before
spapr_h_cas_compose_response() (where htab_shift is added to the
device tree).

In order to prevent the guest from forcing the allocation of large amounts
of qemu memory (or host kernel memory, in the case of KVM HV), we limit
the size of Hashed Page Table (HPT) it is allowed to allocated, based on
its RAM size.
However, the current calculation is not correct: it only adds up the size
of plugged memory, ignoring the base memory size. This patch corrects it.
While we're there, use get_plugged_memory_size() instead of directly
calling pc_existing_dimms_capacity(). The only difference is that it
will abort on failure, which is right: a failure here indicates something
wrong within qemu.

replace sPAPRCPUCoreClass::cpu_class with cpu type name
since it were needed just to get that at points it were
accessed.

spapr core type definition doesn't have any fields that
require it to be defined at runtime. So replace code
that fills in TypeInfo at runtime with static TypeInfo
array that does the same at complie time.

there is a dedicated callback CPUClass::parse_features
which purpose is to convert -cpu features into a set of
global properties AND deal with compat/legacy features
that couldn't be directly translated into CPU's properties.
Create ppc variant of it (ppc_cpu_parse_featurestr) and
move 'compat=val' handling from spapr_cpu_core.c into it.
That removes a dependency of board/core code on cpu_model
parsing and would let to reuse common -cpu parsing
introduced by 6063d4c0
Set "max-cpu-compat" property only if it exists, in practice
it should limit 'compat' hack to spapr machine and allow
to avoid including machine/spapr headers in target/ppc/cpu.c

ppc_cpu_parse_features() is doing practically the same thing as
generic cpu_parse_cpu_model(). So remove duplicated impl. and
reuse generic one.
