Benjamin Herrenschmidt 9e933f4a62 ppc/pnv: add skeleton PowerNV platform
The goal is to emulate a PowerNV system at the level of the skiboot
firmware, which loads the OS and provides some runtime services. Power
Systems have a lower firmware (HostBoot) that does low level system
initialization, like DRAM training. This is beyond the scope of what
qemu will address in a PowerNV guest.

No devices yet, not even an interrupt controller. Just to get started,
some RAM to load the skiboot firmware, the kernel and initrd. The
device tree is fully created in the machine reset op.

Riku Voipio 5e2b40f727 linux-user: disable unicore32 linux-user build
In order to cleanup linux-user, we need support for most relatively
modern syscalls. unicore32 lacks support for syscalls like
epoll_pwait, preventing cleaning up the CONFIG_EPOLL mess.

This patch can be reverted when unicore32 starts either supporting
the syscalls as defined in mainline kernel, or the oldabi interface
gains support for syscalls supported since at kernel 2.6.19 / glibc 2.6

Dmitry Fleytman 6f3fbe4ed0 net: Introduce e1000e device emulation
This patch introduces emulation for the Intel 82574 adapter, AKA e1000e.

This implementation is derived from the e1000 emulation code, and
utilizes the TX/RX packet abstractions that were initially developed for
the vmxnet3 device. Although some parts of the introduced code may be
shared with e1000, the differences are substantial enough so that the
only shared resources for the two devices are the definitions in
hw/net/e1000_regs.h.

Similarly to vmxnet3, the new device uses virtio headers for task
offloads (for backends that support virtio extensions). Usage of
virtio headers may be forcibly disabled via a boolean device property
"vnet" (which is enabled by default). In such case task offloads
will be performed in software, in the same way it is done on
backends that do not support virtio headers.

The device code is split into two parts:

  1. hw/net/e1000e.c: QEMU-specific code for a network device;
  2. hw/net/e1000e_core.[hc]: Device emulation according to the spec.

The new device name is e1000e.

Intel specifications for the 82574 controller are available at:
http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf

Leon Alrae 34fa7e83e1 hw/mips: implement ITC Configuration Tags and Storage Cells
Implement ITC as a single object consisting of two memory regions:

1) tag_io: ITC Configuration Tags (i.e. ITCAddressMap{0,1} registers) which
are accessible by the CPU via CACHE instruction. Also adding
MemoryRegion *itc_tag to the CPUMIPSState so that CACHE instruction will
dispatch reads/writes directly.

2) storage_io: memory-mapped ITC Storage whose address space is configurable
(i.e. enabled/remapped/resized) by writing to ITCAddressMap{0,1} registers.

ITC Storage contains FIFO and Semaphore cells. Read-only FIFO bit in the
ITC cell tag indicates the type of the cell. If the ITC Storage contains
both types of cells then FIFOs are located before Semaphores.

Since issuing thread can get blocked on the access to a cell (in E/F
Synchronized and P/V Synchronized Views) each cell has a bitmap to track
which threads are currently blocked.

Event notifiers are designed for eventfd(2).  They can fall back to
pipes, but according to Paolo, event_notifier_init_fd() really
requires the real thing, and should therefore be under #ifdef
CONFIG_EVENTFD.  Do that.

Its only user is ivshmem, which is currently CONFIG_POSIX.  Narrow it
to CONFIG_EVENTFD.

Paolo Bonzini e351b82611 hw: Add support for LSI SAS1068 (mptsas) device
This adds the SAS1068 device, a SAS disk controller used in VMware that
is oldish but widely supported and has decent performance.  Unlike
megasas, it presents itself as a SAS controller and not as a RAID
controller.  The device corresponds to the mptsas kernel driver in
Linux.

A few small things in the device setup are based on Don Slutz's old
patch, but the device emulation was written from scratch based on Don's
SeaBIOS patch and on the FreeBSD and Linux drivers.  It is 2400 lines
shorter than Don's patch (and roughly the same size as MegaSAS---also
because it doesn't support the similar SPI controller), implements SCSI
task management functions (with asynchronous cancellation), supports
big-endian hosts, has complete support for migration and follows the
QEMU coding standards much more closely.

To write the driver, I first split Don's patch in two parts, with
the configuration bits in one file and the rest in a separate file.
I first left mptconfig.c in place and rewrote the rest, then deleted
mptconfig.c as well.  The configuration pages are still based mostly on
VirtualBox's, though not exactly the same.  However, the implementation
is completely different.  The contents of the pages themselves should
not be copyrightable.

Xiao Guangrong 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

Peter Maydell f72c0a79f7 default-configs/aarch64-linux-user.mak: Remove unused define
The uses of the CONFIG_GDBSTUB_XML define were removed in commit
b77abd95a9, but the define in aarch64-linux-user.mak somehow
escaped the cull (the patchset probably crossed in the mail with
the patches adding aarch64 support). Remove the stray define.
