The PAPR specification requires a certain amount of NVRAM, accessed via
RTAS, which we don't currently implement in qemu. This patch addresses
this deficiency, implementing the NVRAM as a VIO device, with some glue to
instantiate it automatically based on a machine option.
The machine option specifies a drive id, which is used to back the NVRAM,
making it persistent. If nothing is specified, the driver instead simply
allocates space for the NVRAM, which will not be persistent

Currently the lowest "real" irq number for the XICS irq controller (as
opposed to numbers reserved for IPIs and other special purposes) is
hard coded as 16 in two places - in xics_system_init() and in spapr.c.
As well as being generally bad practice, we're going to need to change this
number soon to fit in with the in-kernel XICS implementation. This patch
adds a #define for this number to avoid future breakage.

There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.
This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)
To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.
I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.

At present, using 'system_powerdown' from the monitor or otherwise
instructing qemu to (cleanly) shut down a pseries guest will not work,
because we did not have a method of signalling the shutdown request to the
guest.
PAPR does include a usable mechanism for this, though it is rather more
involved than the equivalent on x86. This involves sending an EPOW
(Environmental and POwer Warning) event through the PAPR event and error
logging mechanism, which also has a number of other functions.
This patch implements just enough of the event/error logging functionality
to be able to send a shutdown event to the guest. At least with modern
guest kernels and a userspace that is up and running, this means that
system_powerdown from the qemu monitor should now work correctly on pseries
guests.

When -usb option is used, global varible usb_enabled is set.
And all the plaform will create one USB controller according
to this variable. In fact, global varibles make code hard
to read.
So this patch is to remove global variable usb_enabled and
add USB option in machine options. All the plaforms will get
USB option value from machine options.
USB option of machine options will be set either by:
* -usb
* -machine type=pseries,usb=on
Both these ways can work now. They both set USB option in
machine options. In the future, the first way will be removed.

This should help us to:
- More easily add or remove machine initialization arguments without
having to change every single machine init function;
- More easily make mechanical changes involving the machine init
functions in the future;
- Let machine initialization forward the init arguments to other
functions more easily.
This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

PAPR hypercalls should only be invoked from the guest kernel, not guest
user programs, that is, with MSR[PR]=0. Currently we check this in
spapr_hypercall, returning H_PRIVILEGE if MSR[PR]=1.
However, under KVM the state of MSR[PR] is already checked by the host
kernel before passing the hypercall to qemu, making this check redundant.
Worse, however, we don't generally synchronize KVM and qemu state on the
hypercall path, meaning that qemu could incorrectly reject a hypercall
because it has a stale MSR value.
This patch fixes the problem by moving the privilege test exclusively to
the TCG hypercall path.

Currently the pseries machine code always attempts to set the size of the
guests's hash page table to 16MB. However, because of the way the POWER
MMU works, a suitable hash page table size should really depend on memory
size. 16MB will be excessive for guests with <1GB and RAM, and may not be
enough for guests with >2GB of RAM (depending on guest page size and
other factors).
The usual given rule of thumb is that the hash table should be 1/64 of
the size of memory, but in fact the Linux guests we are aiming at don't
really need that much. This patch, therefore, changes the hash table
allocation code to aim for 1/128 of the size of RAM (rounding up). When
using KVM, this size may still be adjusted by the host kernel if it is
unable to allocate a suitable (contiguous) table.

A number of things need to occur during reset of the PAPR
paravirtualized platform in a specific order. For example, the hash
table needs to be cleared before the CPUs are reset, so that they
initialize their register state correctly, and the CPUs need to have
their main reset called before we set up the entry point state on the
boot cpu. We also need to have the main qdev reset happen before the
creation and installation of the device tree for the new boot, because
we need the state of the devices settled to correctly construct the
device tree.
We currently do the pseries once-per-reset initializations done from a
reset handler. However we can't adequately control when this handler
is called during the reset - in particular we can't guarantee it
happens after all the qdev resets (since qdevs might be registered
after the machine init function has executed).
This patch uses the new QEMUMachine reset method to to fix this
problem, ensuring the various order dependent reset steps happen in
the correct order.

The current pseries machine init function iterates over the CPUs at several
points, doing various bits of initialization. This is messy; these can
and should be merged into a single iteration doing all the necessary per
cpu initialization. Worse, some of these initializations were setting up
state which should be set on every reset, not just at machine init time.
A few of the initializations simply weren't necessary at all.
This patch, therefore, moves those things that need to be to the
per-cpu reset handler, and combines the remainder into two loops over
the cpus (which also creates them). The second loop is for setting up
hash table information, and will be removed in a subsequent patch also
making other fixes to the hash table setup.
This exposes a bug in our start-cpu RTAS routine (called by the guest to
start up CPUs other than CPU0) under kvm. Previously, this function did
not make a call to ensure that it's changes to the new cpu's state were
pushed into KVM in-kernel state. We sort-of got away with this because
some of the initializations had already placed the secondary CPUs into the
right starting state for the sorts of Linux guests we've been running.
Nonetheless the start-cpu RTAS call's behaviour was not correct and could
easily have been broken by guest changes. This patch also fixes it.

This patch implements MSI and MSI-X support for the pseries PCI host
bridge. To do this it adds:
* A "config_space_address to msi_table" map, since the MSI RTAS calls
take a PCI config space address as an identifier.
* A MSIX memory region to catch msi_notify()/msix_notiry() from
virtio-pci and pass them to the guest via qemu_irq_pulse().
* RTAS call "ibm,change-msi" which sets up MSI vectors for a
device. Note that this call may configure and return lesser number of
vectors than requested.
* RTAS call "ibm,query-interrupt-source-number" which translates MSI
vector to interrupt controller (XICS) IRQ number.

Currently the RTAS functions for handling PCI are registered from the

now, but will break in the future when vfio gives us multiple types of
host bridge for pseries (emulated and pass-through, at least). The
RTAS functions will be common across all host bridge types (and will
call out to different places internally depending on the type).
So, this patch moves the RTAS registration into its own function
called direct from the machine setup code.

Currently, the interfaces in the pseries machine code for assignment
and setup of interrupts pass around qemu_irq objects. That was done
in an attempt not to be too closely linked to the specific XICS
interrupt controller. However interactions with the device tree setup
made that attempt rather futile, and XICS is part of the PAPR spec
anyway, so this really just meant we had to carry both the qemu_irq
pointers and the XICS irq numbers around.
This mess will just get worse when we add upcoming PCI MSI support,
since that will require tracking a bunch more interrupt. Therefore,
this patch reworks the spapr code to just use XICS irq numbers
(roughly equivalent to GSIs on x86) and only retrieve the qemu_irq
pointers from the XICS code when we need them (a trivial lookup).
This is a reworked and generalized version of an earlier spapr_pci
specific patch from Alexey Kardashevskiy.

This adds a qemu-specific hypervisor call to the pseries machine
which allows to do what amounts to memmove, memcpy and xor over
regions of physical memory such as the framebuffer.
This is the simplest way to get usable framebuffer speed from
SLOF since the framebuffer isn't mapped in the VRMA and so would
otherwise require an hcall per 8 bytes access.
The performance is still not great but usable, and can be improved
with a more complex implementation of the hcall itself if needed.
This also adds some documentation for the qemu-specific hypercalls
that we add to PAPR along with a new qemu,hypertas-functions property
that mirrors ibm,hypertas-functions and provides some discoverability
for the new calls.
Note: I chose note to advertise H_RTAS to the guest via that mechanism.
This is done on purpose, the guest uses the normal RTAS interfaces
provided by qemu (including SLOF) which internally calls H_RTAS.
We might in the future implement part (or even all) of RTAS inside the
guest like IBM's firmware does and replace H_RTAS with some finer grained
set of private hypercalls.

The core tcg/kvm code for ppc64 now has at least the outline
capability to support pagesizes beyond the standard 4k and 16MB. The

pagesizes and their correct encodings, and under the right KVM setup
this will be populated with page sizes beyond the standard.
Obviously guests can't use the extra page sizes unless they know
they're present. For the pseries machine, at least, there is a
defined method for conveying exactly this information, the
"ibm-segment-page-sizes" property in the guest device tree.
This patch generates this property using the supported page size

PAPR virtual IO (VIO) devices require a unique, but otherwise arbitrary,
"address" used as a token to the hypercalls which manipulate them.
Currently the pseries machine code does an ok job of allocating these
addresses when the legacy -net nic / -serial and so forth options are used
but will fail to allocate them properly when using -device.
Specifically, you can use -device if all addresses are explicitly assigned.
Without explicit assignment, only one VIO device of each type (network,
console, SCSI) will be assigned properly, any further ones will attempt
to take the same address leading to a fatal error.
This patch fixes the situation by adding a proper address allocator to the
VIO "bus" code. This is used both by -device and the legacy options and
default devices. Addresses can still be explicitly assigned with -device
options if desired.
This patch changes the (guest visible) numbering of VIO devices, but since
their addresses are discovered using the device tree and already differ
from the numbering found on existing PowerVM systems, this does not break
compatibility.

The pseries "xics" interrupt controller, like most interrupt
controllers can support both message (i.e. edge sensitive) interrupts
and level sensitive interrupts, but it needs to know which are which.
When I implemented the xics emulation for qemu, the only devices we
supported were the PAPR virtual IO devices. These devices only use
message interrupts, so they were the only ones I implemented in xics.
Since then, however, we have added support for PCI devices, which use
level sensitive interrupts. It turns out the message interrupt logic
still actually works most of the time for these, but there are
circumstances where we can lost interrupts due to the incorrect
interrupt logic.
This patch, therefore, implements the correct xics level-sensitive
interrupt logic. The type of the interrupt is set when a device
allocates a new xics interrupt.
