David Gibson fd56e0612b pci: Eliminate redundant PCIDevice::bus pointer
The bus pointer in PCIDevice is basically redundant with QOM information.
It's always initialized to the qdev_get_parent_bus(), the only difference
is the type.

Therefore this patch eliminates the field, instead creating a pci_get_bus()
helper to do the type mangling to derive it conveniently from the QOM
Device object underneath.

Eduardo Habkost a5fa336f11 pci: Add interface names to hybrid PCI devices
The following devices support both PCI Express and Conventional
PCI, by including special code to handle the QEMU_PCI_CAP_EXPRESS
flag and/or conditional pcie_endpoint_cap_init() calls:

* vfio-pci (is_express=1, but legacy PCI handled by
  vfio_populate_device())
* vmxnet3 (is_express=0, but PCIe handled by vmxnet3_realize())
* pvscsi (is_express=0, but PCIe handled by pvscsi_realize())
* virtio-pci (is_express=0, but PCIe handled by
  virtio_pci_dc_realize(), and additional legacy PCI code at
  virtio_pci_realize())
* base-xhci (is_express=1, but pcie_endpoint_cap_init() call
  is conditional on pci_bus_is_express(dev->bus)
  * Note that xhci does not clear QEMU_PCI_CAP_EXPRESS like the
    other hybrid devices

Dr. David Alan Gilbert 44b1ff319c migration: pre_save return int
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.

Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.

Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

Dr. David Alan Gilbert 20daa90a20 PCI/migration merge vmstate_pci_device and vmstate_pcie_device
The vmstate_pci_device and vmstate_pcie_devices differ
just in the size of one buffer; combine the two using a _TEST
macro.

I think this is safe as long as everywhere which currently
uses either of these two uses the right type.

One thing that concerns me is that some places use pci_device_load/save
which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE
macro - how are they getting the same irq mangling?

This passes a smoke test migrate of:
./x86_64-softmmu/qemu-system-x86_64 -M pc,accel=kvm -m 1024
./littlefed20.img -device e1000e -device virtio-net -device
e1000 -device virtio-rng -device megasas -device megasas-gen2 -device
ioh3420 -device nec-usb-xhci

Prasad J Pandit 49adc5d3f8 scsi: pvscsi: limit loop to fetch SG list
In PVSCSI paravirtual SCSI bus, pvscsi_convert_sglist can take a very
long time or go into an infinite loop due to two different bugs:

1) the request descriptor data length is defined to be 64 bit. While
building SG list from a request descriptor, it gets truncated to 32bit
in routine 'pvscsi_convert_sglist'. This could lead to an infinite loop
situation large 'dataLen' values when data_length is cast to uint32_t and
chunk_size becomes always zero.  Fix this by removing the incorrect cast.

2) pvscsi_get_next_sg_elem can be called arbitrarily many times if the
element has a zero length.  Get out of the loop early when this happens,
by introducing an upper limit on the number of SG list elements.

Fix by converting it to Error.

For those callers who don't handle the failure, it might happen:
when user want msi on, but he doesn't get what he want because of
msi_init fails silently.

Markus Armbruster da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.

This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.

Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

INTx pin to assert/deassert.

An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices.

Removed irq related fields from state if not used anymore.

Peter Maydell 6783ecf144 hw: Avoid use of QOM type name macros in VMStateDescriptions
The name field in a VMStateDescription is part of the migration state
versioning, so changing it will break migration.  It's therefore a
bad idea to use a QOM typename macro to initialize it, because in
general we're free to rename QOM types as part of code refactoring
and cleanup.  For the handful of devices that were doing this by
mistake, replace the QOM typenames with the corresponding literal
strings.

Paolo Bonzini df32fd1c9f dma: eliminate DMAContext
The DMAContext is a simple pointer to an AddressSpace that is now always
already available.  Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.
