As we register old portio regions via ioport_register, we are also

The only user of ISADevice.ioports is isabus_get_fw_dev_path, and it
only looks at the first entry of the array. Which suggests that this
entire array+sort operation can be replaced by a simple minimum.

Clean up versatile_pci to expose the various PCI mmio regions
properly as separate mmio regions rather than as a single mmio
which uses callbacks to map and unmap everything.

The alarm is a fully general one-shot time comparator, which will be
usable under Linux as a hrtimer source. It's much more flexible than
the RTC source available on real hardware.
The wall clock allows the guest access to the host timekeeping. Much
like the KVM wall clock source for other guests.
Both are accessed via the PALcode Cserve entry point.

This is a DP264 variant, SMP capable, no unusual hardware present.
The emulation does not currently include any PCI IOMMU code.
Hopefully the generic support for that can be merged to HEAD soon.

Currently there is no implementation for set-time-of-day rtas function,
which causes the following warning "setting the clock failed (-1)" on
the guest.
This patch just creates this function, get the timedate diff and store in
the papr environment, so that the correct value will be returned by
get-time-of-day.
In order to try it, just adjust the hardware time, run hwclock --systohc,
so that, on when the system runs hwclock --hctosys, the value is correctly
adjusted, i.e. the host time plus the timediff.

Paulo Bonzini changed the original spapr code, which manually assigned irq
numbers for each virtual device, to allocate them automatically from the
device initialization. That allowed spapr virtual devices to be constructed
with -device, which is a good start. However, the way that patch worked
doesn't extend nicely for the future when we want to support devices other
than sPAPR VIO devices (e.g. virtio and PCI).
This patch rearranges the irq allocation to be global across the sPAPR
environment, so it can be used by other bus types as well.

While working on the emulation of the freescale p2010 (e500v2) I realized that
there's no implementation of booke's timers features. Currently mpc8544 uses
ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for
example booke uses different SPR).

When running with PR KVM, we need to set HIOR directly. Thankfully there
is now a new interface to set registers individually so we can just use that
and poke HIOR into the guest vcpu's HIOR register.
While at it, this also sets SDR1 because -M pseries requires it to run.
With this patch, -M pseries works properly with PR KVM.

Commit 23c5e4ca (convert to memory API) broke the VIA Cuda emulation layer
by not registering the IO structs.
This patch registers them properly and thus makes -M g3beige and -M mac99
work again.

The helper function write_IRQreg was always called with a specific argument on
the type of register to access. Inside the function we were simply doing a
switch on that constant argument again. It's a lot easier to just unfold this
into two separate functions and call each individually.

The RAM_ADDR_FMT macro hides the type of ram_addr_t so that format
strings can be safely used. Make sure to use RAM_ADDR_FMT so that the
build works on 32-bit hosts with Xen enabled. Whether Xen should affect
ppc TCG targets is questionable but a separate issue.
