CPUs that are not the boot CPU need to run in spinning code to check if they
should run off to execute and if so where to jump to. This usually happens
by leaving secondary CPUs looping and checking if some variable in memory
changed.
In an environment like Qemu however we can be more clever. We can just export
the spin table the primary CPU modifies as MMIO region that would event based
wake up the respective secondary CPUs. That saves us quite some cycles while
the secondary CPUs are not up yet.
So this patch adds a PV device that simply exports the spinning table into the
guest and thus allows the primary CPU to wake up secondary ones.

v1 -> v2:
- change into MMIO scheme
- map the secondary NIP instead of 0 1:1
- only map 64MB for TLB, same as u-boot
- prepare code for 64-bit spinnings
v2 -> v3:
- remove r6
- set MAS2_M
- map EA 0
- use second TLB1 entry
v3 -> v4:
- change to memoryops
v4 -> v5:
- fix endianness bugs
v5 -> v6:
- add header
The MPIC has some funny feature where it maps different registers to an MMIO
region depending which CPU accesses them.
To be able to reflect that, we need to make OpenPIC be compiled in the target
code, so it can access cpu_single_env.

The memory API separates the attributes of a memory region (its size, how
reads or writes are handled, dirty logging, and coalescing) from where it
is mapped and whether it is enabled. This allows a device to configure
a memory region once, then hand it off to its parent bus to map it according
to the bus configuration.
Hierarchical registration also allows a device to compose a region out of
a number of sub-regions with different properties; for example some may be
RAM while others may be MMIO.

On IA32 host or IA32 PAE host, at present, generally, we can't create
an HVM guest with more than 2G memory, because generally it's almost
impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.
Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the
lock option, so mapcache will not unmap these ram_ptr.
Blocks that do not belong to the RAM, but usually to a device ROM or to
a framebuffer, are handled in a separate function. So the whole RAMBlock
can be map.

PAPR defines an interrupt control architecture which is logically divided
into ICS (Interrupt Control Presentation, each unit is responsible for
presenting interrupts to a particular "interrupt server", i.e. CPU) and
ICS (Interrupt Control Source, each unit responsible for one or more
hardware interrupts as numbered globally across the system). All PAPR
virtual IO devices expect to deliver interrupts via this mechanism. In
Linux, this interrupt controller system is handled by the "xics" driver.
On pSeries systems, access to the interrupt controller is virtualized via
hypercalls and RTAS methods. However, the virtualized interface is very
similar to the underlying interrupt controller hardware, and similar PICs
exist un-virtualized in some other systems.
This patch implements both the ICP and ICS sides of the PAPR interrupt
controller. For now, only the hypercall virtualized interface is provided,
however it would be relatively straightforward to graft an emulated
register interface onto the underlying interrupt logic if we want to add
a machine with a hardware ICS/ICP system in the future.
There are some limitations in this implementation: it is assumed for now
that only one instance of the ICS exists, although a full xics system can
have several, each responsible for a different group of hardware irqs.
ICP/ICS can handle both level-sensitve (LSI) and message signalled (MSI)
interrupt inputs. For now, this implementation supports only MSI
interrupts, since that is used by PAPR virtual IO devices.

On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations. On logical partitions
under a hypervisor, many of the RTAS functions require hypervisor
privilege. For simplicity, therefore, hypervisor systems typically
implement the in-partition RTAS as just a tiny wrapper around a hypercall
which actually implements the various RTAS functions.
This patch implements such a hypercall based RTAS for our emulated pSeries
machine. A tiny in-partition "firmware" calls a new hypercall, which
looks up available RTAS services in a table.

This patch adds a "pseries" machine to qemu. This aims to emulate a
logical partition on an IBM pSeries machine, compliant to the
"PowerPC Architecture Platform Requirements" (PAPR) document.
This initial version is quite limited, it implements a basic machine
and PAPR hypercall emulation. So far only one hypercall is present -
H_PUT_TERM_CHAR - so that a (write-only) console is available.
Multiple CPUs are permitted, with SMP entry handled kexec() style.
The machine so far more resembles an old POWER4 style "full system
partition" rather than a modern LPAR, in that the guest manages the
page tables directly, rather than via hypercalls.
The machine requires qemu to be configured with --enable-fdt. The
machine can (so far) only be booted with -kernel - i.e. no partition
firmware is provided.

This patch add support for a system control block. It is supposed to
act as helper for the emulated program. E.g. shutting down the VM or
printing test results. This model is intended for testing purposes only and
doesn't fit to any real hardware. Therefore, it is not added to any board
by default. Instead a user has to add it explicitly with the '-device'
commandline parameter.

This patch adds the JTAG UART model. It is accessed through special control
registers and opcodes. Therefore the translation uses callbacks to this
model.

This patch adds the interrupt controller of the lm32. Because the PIC is
accessed through special control registers and opcodes, there are callbacks
from the lm32 translation code to this model.

If kvmclock is used, which implies the kernel supports it, register a
kvmclock device with the sysbus. Its main purpose is to save and restore
the kernel state on migration, but this will also allow to visualize it
one day.

which allows targets to handle various FLAT aspects in their own way.
For the common behavior, the new functions get stubbed out.

Leon3 is an open-source VHDL System-On-Chip, well known in space industry (more
information on http://www.gaisler.com).
Leon3 is made of multiple components available in the GrLib VHDL library.
Three devices are implemented: uart, timers and IRQ manager.
You can find code for these peripherals in the grlib_* files.

This patch replaces explicit bswaps with endianness hints to the

Because we don't depend on the target endianness anymore, we can also
move the driver over to Makefile.objs.

The e1000 has compatibility code to handle big endianness which makes it
mandatory to be recompiled on different targets.
With the generic mmio endianness solution, there's no need for that anymore.
We just declare all mmio to be little endian and call it a day.
Because we don't depend on the target endianness anymore, we can also
move the driver over to Makefile.objs.

qxl is a paravirtual graphics card. The qxl device is the bridge
between the guest and the spice server (aka libspice-server). The
spice server will send the rendering commands to the spice client, which
will actually render them.
The spice server is also able to render locally, which is done in case
the guest wants read something from video memory. Local rendering is
also used to support display over vnc and sdl.
qxl is activated using "-vga qxl". qxl supports multihead, additional
cards can be added via '-device qxl".
[ v2: add copyright to files ]
[ v2: use qemu-common.h for standard includes ]
[ v2: create separate qxl-vga device for primary ]
