Eduardo Habkost 72d164aa73 piix: Add kvmclock_enabled, pci_enabled globals
This looks like a step backwards, but it will allow pc-0.1[0123] and
isapc to follow the same compat+init pattern used by the other
machine-types, allowing us to generate all init function using the same
macro later.

Eduardo Habkost 865906f7fd pc: Don't use QEMUMachine anymore
Now that we have a DEFINE_PC_MACHINE helper macro that just requires an
initialization function, it is trivial to convert them to register a QOM
machine class directly, instead of using QEMUMachine.

This will simplify the DEFINE_PC_MACHINE macro, and will help us to

Eduardo Habkost b6b5c8e492 pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.

This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.

Comments about specific cases:

pc-*-2.1:

  Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin"

  PC_*_2_2_MACHINE_OPTIONS is:
      PC_*_2_3_MACHINE_OPTIONS
  which is expanded to:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin",
      .default_display = "std"

  The only difference between 2_1 and 2_2 is .default_display, that's why
  we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
  multiple initializers for a field is allowed by C99, and the last
  initializer overrides the previous ones.

  So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
  as:
      PC_*_2_2_MACHINE_OPTIONS,
      .default_display = NULL

pc-*-1.7:

  PC_*_1_7_MACHINE_OPTIONS was defined as:
      PC_*_MACHINE_OPTIONS

  PC_*_2_0_MACHINE_OPTIONS is defined as:
      PC_*_2_1_MACHINE_OPTIONS
  which is expanded to:
      PC_*_2_2_MACHINE_OPTIONS,
      .default_display = NULL
  which is expanded to:
      PC_*_2_3_MACHINE_OPTIONS,
      .default_display = NULL
  which is expanded to:
      PC_*_MACHINE_OPTIONS,
      .default_machine_opts = "firmware=bios-256k.bin",
      .default_display = "std",
      .default_display = NULL  /* overrides the previous line */

  So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
  PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
  is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).

  So we can keep the macro reuse pattern and define
  PC_*_2_0_MACHINE_OPTIONS as:
      PC_*_2_0_MACHINE_OPTIONS,
      .default_machine_opts = NULL

pc-*-2.4 (alias and is_default fields):

  Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
  and clear it in the 2.3 macro (that reuses the 2.4 macro).

hw_machine:

  As all the machines older than v1.0 set hw_version explicitly, we can
  safely move the field to the MACHINE_OPTIONS macros without affecting
  the other versions that reuse them.

init function:

  Some machines had the init function set inside the MACHINE_OPTIONS
  macro. Move it to the QEMUMachine declaration, to keep it consistent
  with the other machines.

Eduardo Habkost faf7e4254f piix: Move pc-0.1[23] rombar compat props to PC_COMPAT_0_13
The VGA and vmware-svga rombar compat properties were added by commit
281a26b15b, but only to pc-0.13 and
pc-0.12. This breaks the PC_COMPAT_* nesting pattern we currently
follow.

The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they
shouldn't be affected at all.

Eduardo Habkost d765519bef piix: Move pc-0.13 virtio-9p-pci compat to PC_COMPAT_0_13
The compat property was added by commit
9dbcca5aa1, and the pc-0.12 and older
machine-types were not changed because virtio-9p-pci was introduced on QEMU
0.13 (commit 9f10751365). The only problem is
that this breaks the PC_COMPAT_* nesting pattern we currently use.

So, move the property to PC_COMPAT_0_13. This make pc-0.12 and older inherit
it, but that shouldn't be an issue as QEMU 0.12 didn't have virtio-9p-pci.

As those variables are overwritten in pc-0.10 too, they can be inherited

Those properties were introduced by commit
3827cdb1c3. They were not duplicated into
pc-0.13 and older because 0.14 was the first QEMU version supporting
qxl. The only problem is that this breaks the PC_COMPAT_* nesting
pattern we currently use.

So, move the properties to PC_COMPAT_0_14. This makes pc-0.13 and older
inherit them, but that shouldn't be an issue as QEMU 0.13 didn't support
qxl.

This patch adds the virtio-input-hid base class and
virtio-{keyboard,mouse,tablet} subclasses building on the base class.
They are hooked up to the qemu input core and deliver input events
to the guest like all other hid devices (ps/2 kbd, usb tablet, ...).

Using them is as simple as adding "-device virtio-tablet-device" to
your command line, for use all transports except pci.  virtio-pci
support comes as separate patch, once virtio-pci got virtio 1.0
support.

This continues the IOMMU fix from 2.3, where we should not attempt
to remap the CLB or FIS RX buffers if the AHCI device is currently
running.

The same applies to migration: keep our mitts off these registers
unless the device is supposed to be on.

Does not impact backwards compatibility for the AHCI device.

Gerd Hoffmann a48da7b5bc serial: fix multi-pci card error cleanup.
Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.

Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

Fabian Aggeler c27a5ba948 hw/intc/arm_gic: Add Interrupt Group Registers
The Interrupt Group Registers allow the guest to configure interrupts
into one of two groups, where Group0 are higher priority and may
be routed to IRQ or FIQ, and Group1 are lower priority and always
routed to IRQ. (In a GIC with the security extensions Group0 is
Secure interrupts and Group 1 is NonSecure.)
The GICv2 always supports interrupt grouping; the GICv1 does only
if it implements the security extensions.

This patch implements the ability to read and write the registers;
the actual functionality the bits control will be added in a
subsequent patch.

Fabian Aggeler 5543d1abb6 hw/intc/arm_gic: Add Security Extensions property
Add a QOM property which allows the GIC Security Extensions to be
enabled. These are an optional part of the GICv1 and GICv2 architecture.
This commit just adds the property and some sanity checks that it
is only enabled on GIC revisions that support it.

The only valid BlockBackend to pass to sd_reset() is the one for
the SD card, which is sd->blk. Drop the second argument from this
function in favour of having it just use sd->blk.

Adrian Huang 165cdaf857 armv7m_nvic: systick: Reload the RELOAD value and count down only if ENABLE bit is set
Consider the following pseudo code to configure SYSTICK (The
recommended programming sequence from "the definitive guide to the
arm cortex-m3"):
    SYSTICK Reload Value Register = 0xffff
    SYSTICK Current Value Register = 0
    SYSTICK Control and Status Register = 0x7

The pseudo code "SYSTICK Current Value Register = 0" leads to invoking
systick_reload(). As a consequence, the systick.tick member is updated
and the systick timer starts to count down when the ENABLE bit of
SYSTICK Control and Status Register is cleared.

The worst case is that: during the system initialization, the reset
value of the SYSTICK Control and Status Register is 0x00000000.
When the code "SYSTICK Current Value Register = 0" is executed, the
systick.tick member is accumulated with "(s->systick.reload + 1) *
systick_scale(s)". The systick_scale() gets the external_ref_clock
scale because the CLKSOURCE bit of the SYSTICK Control and Status
Register is cleared. This is the incorrect behavior because of the
code "SYSTICK Control and Status Register = 0x7". Actually, we want
the processor clock instead of the external reference clock.

This incorrect behavior defers the generation of the first interrupt.

The patch fixes the above-mentioned issue by setting the systick.tick
member and modifying the systick timer only if the ENABLE bit of
the SYSTICK Control and Status Register is set.

In addition, the Cortex-M3 Devices Generic User Guide mentioned that
"When ENABLE is set to 1, the counter loads the RELOAD value from the
SYST RVR register and then counts down". This patch adheres to the
statement of the user guide.

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.
