0eb9054c60 pseries: Remove versions from mc->desc
Currently, the versioned spapr machine types put the machine type version
into the description string.  PC does not do this, using just the name
itself to distinguish.  Doing the same lets us move setting the description
into the common base class, simplifying the code slightly.

64f0f70a00 pseries: Remove redundant calls to spapr_machine_initfn()
The instance_init() functions for several of the pseries-x.y versioned
machine types explicitly call spapr_machine_initfn().  But that's the
instance_init function for the common parent of all those machine types,
so will already have been called beforehand by the QOM infrastructure.

Remove the redundant calls.

1c5f29bbc8 pseries: Rearrange versioned machine type code
hw/ppc/spapr.c has a number of definitions related to the various versioned
machine types ("pseries-2.1" .. "pseries-2.5") it defines.  These are
mostly arranged by type of function first, then machine version second, and
it's not consistent about whether it goes in increasing or decreasing
version order.

This rearranges the code to keep all the definitions for a particular
machine version together, and arrange then consistently in order most
recent to least recent.

This brings us closer to matching the way PC does things, and makes later
cleanups easier to follow.

Apart from adding some comments marking each section, this is a pure
mechanical rearrangement with no semantic changes.

aec39c5349 pseries: Remove redundant setting of mc->name for pseries-2.5 machine
98cec76 "machine: Set MachineClass::name automatically" removed the setting
of mc->name for the pseries machine types, since it can be derived
automatically from the type names constructed with MACHINE_TYPE_NAME().

Unfortunately fb0fc8f "spapr: Create pseries-2.5 machine" went in later and
brought one of them back.

This removes it again.

3dc0a66d26 spapr: Add /system-id
Section B.6.2.1 Root Node Properties of PAPR specification defines
a set of properties which shall be present in the device tree root,
one of these properties is "system-id" which "should be unique across
all systems and all manufacturers". Since UUID is meant to be unique,
it makes sense to use it as "system-id".

This adds "system-id" property to the device tree root when not empty.

4083733db5 ui/curses: Fix color attribute of monitor for curses
Current text_console_update() writes totally broken color attributes
to console_write_ch(). The format now is writing,

[WRONG]
	bold << 21 | fg << 12 | bg << 8 | char
	fg == 3bits curses color number
	bg == 3bits curses color number

I can't see this format is where come from. Anyway, this doesn't work
at all.

What curses expects is actually (and vga.c is using),

[RIGHT]
	bold << 21 | bg << 11 | fg << 8 | char
	fg == 3bits vga color number
	bg == 3bits vga color number

And curses set COLOR_PAIR() up to match this format, and curses's
chtype. I.e,

	bold | color_pair | char
	color_pair == (bg << 3 | fg)

To fix, this simply uses VGA color number everywhere except curses.c
internal. Then, convert it to above [RIGHT] format to write by
console_write_ch(). And as bonus, this reduces to expose curses define
to other parts (removes COLOR_* from console.c).

[Tested the first line is displayed as white on blue back for monitor
in curses console]

087462c773 ohci: clear pending SOF on suspend
On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.

On suspend, if a SOF interrupt is raised between the stop of the
device processing and the change of the device internal state to
OHCI_USB_SUSPEND (QEMU stops SOF timer on this state change), this
interrupt is never acknowledged.

This patch clears pending SOF interrupt on OHCI_USB_SUSPEND setting.

Some details:

- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
  only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
  So if this interrupt happens and the driver is not in this state,
  the function is called again and again, moving the system to a
  CPU starvation.

- ohci_rh_suspend(): the function stop the operation and acknowledge
  pending interrupts (but doesn't disable it). Later in the function,
  the device is moved to OHCI_SUSPEND_STATE, and the driver to
  OHCI_RH_SUSPENDED. If between the moment when the interrupt is
  acknowledged and the moment when the device is suspended a new
  interrupt is raised, it will be never acknowledged because the
  driver is now not in OHCI_RH_RUNNING state.

fd0a10cd20 ohci: delay first SOF interrupt
On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.

This does not happen on real hardware because real hardware never send
interrupt immediately after the controller has been moved to OPERATION state.

This patch tries to delay the first SOF interrupt to let driver exits from
the critical section (which is not protected against interrupts...)

Some details:

- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
  only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
  So if this interrupt happens and the driver is not in this state,
  the function is called again and again, moving the system to a
  CPU starvation.

- ohci_rh_resume(): the driver re-enables operation with OHCI_USB_OPER.
  In QEMU this start the SOF timer and QEMU starts to send IRQs. As
  the driver is not in OHCI_STATE_RUNNING and not protected against IRQ,
  the ohci_irq() can be called and the driver never moved to
  OHCI_STATE_RUNNING.

4b3a4f2d45 virtio-9p: use accessor to get thread_pool
The aio_context_new() function does not allocate a thread pool. This is
deferred to the first call to the aio_get_thread_pool() accessor. It is
hence forbidden to access the thread_pool field directly, as it may be
NULL. The accessor *must* be used always.

439e2a6e10 acpi: aml: add helper for Opcode Arg2 Arg2 [Dst] AML pattern
Currently AML API doesn't compose terms in form of
following pattern:

   Opcode Arg2 Arg2 [Dst]

but ASL used in piix4/q35 DSDT ACPI tables uses that
form, so for clean conversion of it, AML API should
be able to handle an optional 'Dst' argumet used there.

Since above pattern is used by arithmetic/bit ops,
introduce helper that they could reuse.
It reduces code duplication in existing 5 aml_foo()
functions and also will prevent more duplication
when exiting functions are extended to support
optional 'Dst' argument.

772863954c nvdimm acpi: build ACPI nvdimm devices
NVDIMM devices is defined in ACPI 6.0 9.20 NVDIMM Devices

There is a root device under \_SB and specified NVDIMM devices are under the
root device. Each NVDIMM device has _ADR which returns its handle used to
associate MEMDEV structure in NFIT

Currently, we do not support any function on _DSM, that means, NVDIMM
label data has not been supported yet

87252e1b61 nvdimm acpi: build ACPI NFIT table
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)

Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info

- MEM DEV structure, it has the @handle which is used to associate specified
  ACPI NVDIMM  device we will introduce in later patch.
  Also we can happily ignored the memory device's interleave, the real
  nvdimm hardware access is hidden behind host

- DCR structure, it defines vendor ID used to associate specified vendor
  nvdimm driver. Since we only implement PMEM mode this time, Command
  window and Data window are not needed

The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100  -object \
memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \
nvdimm,memdev=mem1,id=nv1

It is disabled on default
