Pavel Pisa 733210e754 hw/net/can: SJA1000 chip register level emulation for QEMU
The core SJA1000 support is independent of following
patches which map SJA1000 chip to PCI boards.

The work is based on Jin Yang GSoC 2013 work funded
by Google and mentored in frame of RTEMS project GSoC
slot donated to QEMU.

Rewritten for QEMU-2.0+ versions and architecture cleanup
by Pavel Pisa (Czech Technical University in Prague).

Pavel Pisa d18957dbcc net/can: simple messages transport implementation for QEMU
The CanBusState state structure is created for each
emulated CAN channel. Individual clients/emulated
CAN interfaces or host interface connection registers
to the bus by CanBusClientState structure.

The CAN core is prepared to support connection to the
real host CAN bus network. The commit with such support
for Linux SocketCAN follows.

Implementation is as simple as possible.  There is no state to be
migrated, and messages prioritization and queuing are not considered
for now.  But it is intended to be extended when need arises.

Changpeng Liu 00343e4b54 vhost-user-blk: introduce a new vhost-user-blk host device
This commit introduces a new vhost-user device for block, it uses a
chardev to connect with the backend, same with Qemu virito-blk device,
Guest OS still uses the virtio-blk frontend driver.

To use it, start QEMU with command line like this:

qemu-system-x86_64 \
    -chardev socket,id=char0,path=/path/vhost.socket \
    -device vhost-user-blk-pci,chardev=char0,num-queues=2, \
            bootindex=2... \

Users can use different parameters for `num-queues` and `bootindex`.

Different with exist Qemu virtio-blk host device, it makes more easy
for users to implement their own I/O processing logic, such as all
user space I/O stack against hardware block device. It uses the new
vhost messages(VHOST_USER_GET_CONFIG) to get block virtio config
information from backend process.

Thomas Huth 03bf6b5c08 default-configs: Enable CONFIG_VMXNET3_PCI only on x86
The device can not be instantiated on many non-x86 and just prints
some error messages, e.g.:

$ qemu-system-ppc64 -device vmxnet3 -M g3beige
[vmxnet3][WR][vmxnet3_init_msix]: Failed to initialize MSI-X, error -95
[vmxnet3][WR][vmxnet3_pci_realize]: Failed to initialize MSI-X, configuration is inconsistent.

Since vmxnet3 is a para-virtualized device that is only useful on x86,
it should also only be enabled on the x86 targets.

Thomas Huth d321e6d58e default-configs: Replace $(and ...) with $(call land, ...)
Using $(and ...) is dangerous here: It only works as long as the first
argument is set to 'y' or completely unset. It does not work if the
first argument is set to 'n' for example. Let's use the "land" make
function instead which has been written explicitely for this purpose.

Marc-André Lureau e6a74868d9 build-sys: add --disable-vhost-user
Learn to compile out vhost-user (net, scsi & upcoming users). Keep it
enabled by default on non-win32, that is assumed to be POSIX. Fail if
trying to enable it on win32.

When trying to make a vhost-user netdev, it gives the following error:

-netdev vhost-user,id=foo,chardev=chr-test: Parameter 'type' expects a netdev backend type

And similar error with the HMP/QMP monitors.

While at it, rename CONFIG_VHOST_NET_TEST CONFIG_VHOST_USER_NET_TEST
since it's a vhost-user specific variable.

Peter Maydell ab7a75b553 configure: Rename CONFIG_IVSHMEM to CONFIG_IVSHMEM_DEVICE
The current CONFIG_IVSHMEM is confusing, because it looks like it's a
flag for "do we have ivshmem support?", but actually it's a flag for
"is the ivshmem PCI device being compiled?" (and implicitly "do we
have ivshmem support?" is tested with CONFIG_EVENTFD).

Rename it to CONFIG_IVSHMEM_DEVICE to clear this confusion up;
shortly we will add a new CONFIG_IVSHMEM which really does indicate
whether the host can support ivshmem.

Felipe Franciosi f12c1ebddf vhost-user-scsi: Introduce vhost-user-scsi host device
This commit introduces a vhost-user device for SCSI. This is based
on the existing vhost-scsi implementation, but done over vhost-user
instead. It also uses a chardev to connect to the backend. Unlike
vhost-scsi (today), VMs using vhost-user-scsi can be live migrated.

To use it, start Qemu with a command line equivalent to:

qemu-system-x86_64 \
       -chardev socket,id=vus0,path=/tmp/vus.sock \
       -device vhost-user-scsi-pci,chardev=vus0,bus=pci.0,addr=...

A separate commit presents a sample application linked with libiscsi to
provide a backend for vhost-user-scsi.

David Gibson 1fc125f567 Allow ISA bus to be configured out
Currently, the code to handle the legacy ISA bus is always included in
qemu.  However there are lots of platforms that don't include ISA legacy
devies, and quite a few that have never used ISA legacy devices at all.

This patch allows the ISA bus code to be disabled in the configuration for
platforms where it doesn't make sense.

For now, the default configs are adjusted to include ISA on all platforms
including PCI: anything with PCI can at least in principle add an i82378
PCI->ISA bridge.  Also, CONFIG_IDE_CORE which is already in pci.mak
requires ISA support.

We also explicitly enable ISA on some other non-PCI platforms which include
ISA devices: moxie, sparc and unicore32.  We may want to pare this down in
future.

The platforms that will lose ISA by default are: cris, lm32, microblazeel,
microblaze, openrisc, s390x, tricore, xtensaeb, xtensa.  As far as I can
tell none of these ever used ISA.

David Gibson 1401c322c8 Split serial-isa into its own config option
At present, the core device model code for 8250-like serial ports
(serial.c) and the code for serial ports attached to ISA-style legacy IO
(serial-isa.c) are both controlled by the CONFIG_SERIAL variable.

There are lots and lots of embedded platforms that have 8250-like serial
ports but have never had anything resembling ISA legacy IO.  Therefore,
split serial-isa into its own CONFIG_SERIAL_ISA option so it can be
disabled for platforms where it's not appropriate.

For now, I enabled CONFIG_SERIAL_ISA in every default-config where
CONFIG_SERIAL is enabled, excepting microblaze, or32, and xtensa.  As best
as I can tell, those platforms never used legacy ISA, and also don't
include PCI support (which would allow connection of a PCI->ISA bridge
and/or a southbridge including legacy ISA serial ports).

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:

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.

Scott Feldman dc488f8880 rocker: add new rocker switch device
Rocker is a simulated ethernet switch device.  The device supports up to 62
front-panel ports and supports L2 switching and L3 routing functions, as well
as L2/L3/L4 ACLs.  The device presents a single PCI device for each switch,
with a memory-mapped register space for device driver access.

Rocker device is invoked with -device, for example a 4-port switch:

  -device rocker,name=sw1,len-ports=4,ports[0]=dev0,ports[1]=dev1, \
         ports[2]=dev2,ports[3]=dev3

Each port is a netdev and can be paired with using -netdev id=<port name>.

rocker: add support for flow modification

We had support for flow add/del.  This adds support for flow mod.  I needed
this for L3 support where an existing route is modified using NLM_F_REPLACE.
For example:

  ip route add 12.0.0.0/30 nexthop via 11.0.0.1 dev swp1
  ip route change 12.0.0.0/30 nexthop via 11.0.0.9 dev swp2

The first cmd adds the route.  The second cmd changes the existing route by
changing its nexthop info.

In the device, a mod operation results in the matching flow enty being modified
with the new settings.  This is atomic to the device.

building qemu.

Full details are available at:
 http://buildbot.b1-systems.de/qemu/builders/default_i386_rhel61/builds/304

The proper fix is non-trivial so let's disable the build by default until it's
fixed properly.

Hannes Reinecke e8f943c3bc megasas: LSI Megaraid SAS HBA emulation
This patch adds an emulation for the LSI Megaraid SAS 8708EM2 HBA.
I've tested it to work with Linux, Windows Vista, and Windows7.

Hector Martin 62c6ae04cf xhci: Initial xHCI implementation
Based on the implementation from Hector Martin <hector@marcansoft.com>

Hectors's implementation completely sidestepped the qemu usb system and
used libusb directly for usb device pass through.  So I've ripped out
the libusb bits (or left them in disabled, as reference for further
coding) and hooked up the qemu subsystem instead.  That work is not
complete yet though, partly due to limitations of the qemu usb
subsystem.  Nevertheless I think it is better to continue development
in-tree, especially as the qemu usb bits need a bunch of improvements
too for decent usb 3.0 support.

Current state:
  - usb-storage emulation should work ok.
  - Devices which need constant polling (HID emulation like usb-tablet)
    are known to not work.
  - ISO xfers are not implemented yet.
  - superspeed ports are not implemented yet.
  - usb pass-through is completely untested so far.

Gerd Hoffmann 94527ead7e usb: add ehci adapter
This patch finally merges the EHCI host adapter aka USB 2.0 support.

Based on the ehci bits collected @ git://git.kiszka.org/qemu.git ehci

EHCI has a long out-of-tree history.  Project was started by Mark
Burkley, with contributions by Niels de Vos.  David S. Ahern continued
working on it.  Kevin Wolf, Jan Kiszka and Vincent Palatin contributed
bugfixes.

/me (Gerd Hoffmann) picked it up where it left off, prepared the code
for merge, fixed a few bugs and added basic user docs.
