5aa8136020 pci: move REDHAT_SDHCI device ID to make room for Rocker
The rocker device uses same PCI device ID as sdhci.  Since rocker device driver
has already been accepted into Linux 3.18, and REDHAT_SDHCI device ID isn't
used by any drivers, it's safe to move REDHAT_SDHCI device ID, avoiding
conflict with rocker.

07abe45c48 hw/arm: pass pristine kernel image to guest firmware over fw_cfg
Introduce the new boolean field "arm_boot_info.firmware_loaded". When this
field is set, it means that the portion of guest DRAM that the VCPU
normally starts to execute, or the pflash chip that the VCPU normally
starts to execute, has been populated by board-specific code with
full-fledged guest firmware code, before the board calls
arm_load_kernel().

Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board
code has set up the global firmware config instance, for arm_load_kernel()
to find with fw_cfg_find().

Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been
possible to specify independently on the command line. The following cases
should be considered:

nr  -bios    -pflash  -kernel  description
             unit#0
--  -------  -------  -------  -------------------------------------------
1   present  present  absent   Board code rejects this case, -bios and
    present  present  present  -pflash unit#0 are exclusive. Left intact
                               by this patch.

2   absent   absent   present  Traditional kernel loading, with qemu's
                               minimal board firmware. Left intact by this
                               patch.

3   absent   present  absent   Preexistent case for booting guest firmware
    present  absent   absent   loaded with -bios or -pflash. Left intact
                               by this patch.

4   absent   absent   absent   Preexistent case for not loading any
                               firmware or kernel up-front. Left intact by
                               this patch.

5   present  absent   present  New case introduced by this patch: kernel
    absent   present  present  image is passed to externally loaded
                               firmware in unmodified form, using fw_cfg.

An easy way to see that this patch doesn't interfere with existing cases
is to realize that "info->firmware_loaded" is constant zero at this point.
Which makes the "outer" condition unchanged, and the "inner" condition
(with the fw_cfg-related code) dead.

7d48a0f721 hw/loader: split out load_image_gzipped_buffer()
In the next patch we'd like to reuse the image decompression facility
without installing the output as a ROM at a specific guest-phys address.

In addition, expose LOAD_IMAGE_MAX_GUNZIP_BYTES, because that's a
straightforward "max_sz" argument for the new load_image_gzipped_buffer().

6c87e3d596 fw_cfg_mem: expose the "data_width" property with fw_cfg_init_mem_wide()
We rebase fw_cfg_init_mem() to the new function for compatibility with
current callers.

The behavior of the (big endian) multi-byte data reads is best shown
with a qtest session.  Here, we are reading the first six bytes of
the UUID

    $ arm-softmmu/qemu-system-arm -M virt -machine accel=qtest \
         -qtest stdio -uuid 4600cb32-38ec-4b2f-8acb-81c6ea54f2d8
>>> writew 0x9020008 0x0200
<<< OK
>>> readl 0x9020000
<<< OK 0x000000004600cb32

Remember this is big endian.  On big endian machines, it is stored
directly as 0x46 0x00 0xcb 0x32.

On a little endian machine, we have to first swap it, so that it becomes
0x32cb0046.  When written to memory, it becomes 0x46 0x00 0xcb 0x32
again.

Reading byte-by-byte works too, of course:

>>> readb 0x9020000
<<< OK 0x0000000000000038
>>> readb 0x9020000
<<< OK 0x00000000000000ec

Here only a single byte is read at a time, so they are read in order
similar to the 1-byte data port that is already in PPC and SPARC
machines.

5712db6ae5 fw_cfg: hard separation between the MMIO and I/O port mappings
We are going to introduce a wide data register for fw_cfg, but only for
the MMIO mapped device. The wide data register will also require the
tightening of endiannesses.

However we don't want to touch the I/O port mapped fw_cfg device at all.

Currently QEMU provides a single fw_cfg device type that can handle both
I/O port and MMIO mapping. This flexibility is not actually exploited by
any board in the tree, but it renders restricting the above changes to
MMIO very hard.

Therefore, let's derive two classes from TYPE_FW_CFG: TYPE_FW_CFG_IO and
TYPE_FW_CFG_MEM.

TYPE_FW_CFG_IO incorporates the base I/O port and the related combined
MemoryRegion. (NB: all boards in the tree that use the I/O port mapped
flavor opt for the combined mapping; that is, when the data port overlays
the high address byte of the selector port. Therefore we can drop the
capability to map those I/O ports separately.)

TYPE_FW_CFG_MEM incorporates the base addresses for the MMIO selector and
data registers, and their respective MemoryRegions.

The "realize" and "props" class members are specific to each new derived
class, and become unused for the base class. The base class retains the
"reset" member and the "vmsd" member, because the reset functionality and
the set of migrated data are not specific to the mapping.

The new functions fw_cfg_init_io() and fw_cfg_init_mem() expose the
possible mappings in separation. For now fw_cfg_init() is retained as a
compatibility shim that enforces the above assumptions.

Adds the secure_boot boolean field to the arm_boot_info descriptor.  This
fields is used to indicate whether Linux should boot into secure or non-secure
state if the ARM EL3 feature is enabled.  The default is to leave the CPU in an
unaltered reset state.  On EL3 enabled systems, the reset state is secure and
can be overridden by setting the added field to false.

4cae4d5aca hmp: fix regression of HMP device_del auto-completion
The commits:
 - 6a1fa9f5 (monitor: add del completion for peripheral device)
 - 66e56b13 (qdev: add qdev_build_hotpluggable_device_list helper)

cause a QEMU crash when trying to use HMP device_del auto-completion.
It can be easily reproduced by:
    <qemu-bin> -enable-kvm  ~/images/fedora.qcow2 -monitor stdio -device virtio-net-pci,id=vnet

    (qemu) device_del
    /home/mapfelba/git/upstream/qemu/hw/core/qdev.c:941:qdev_build_hotpluggable_device_list: Object 0x7f6ce04e4fe0 is not an instance of type device
    Aborted (core dumped)

The root cause is qdev_build_hotpluggable_device_list going recursively over
all peripherals and their children assuming all are devices. It doesn't work
since PCI devices have at least on child which is a memory region (bus master).

Solved by observing that all devices appear as direct children of
/machine/peripheral container. No need of going recursively
over all the children.

or

c/s b154537ad0

moved the testing of xen_enabled() from pc_init1() to
pc_machine_initfn().

xen_enabled() does not return the correct value in
pc_machine_initfn().

Changed vmport from a bool to an enum.  Added the value "auto" to do
the old way.  Move check of xen_enabled() back to pc_init1().

91aa70ab2a pc: align DIMM's address/size by backend's alignment value
Performance wise it's better to align GVA by the backend's
page size.

Also do not allow to create DIMM device with suboptimal
size (i.e. not aligned to backends page size) to aviod
memory loss.

Do above only for 2.2 and newer machine types to avoid
breaking working configs with 2.1 machine type.

92a37a04d6 pc: limit DIMM address and size to page aligned values
When running in KVM mode, kvm_set_phys_mem() will silently
fail if registered MemoryRegion address/size is not page
aligned. Causing memory hotplug failure in guest.

Mapping non aligned MemoryRegion in TCG mode 'works', but
sane guest OS still expects page aligned memory module
and fails to initialize it if it's not aligned.

So do not allow non aligned (i.e. valid) address/size
values for DIMM to avoid either KVM failure or guest
issues caused by it.

7634fe3c27 sysbus: Add new platform bus helper device
We need to support spawning of sysbus devices dynamically via the command line.
The easiest way to represent these dynamically spawned devices in the guest's
memory and IRQ layout is by preallocating some space for dynamic sysbus devices.

This is what the "platform bus" device does. It is a sysbus device that exports
a configurably sized MMIO region and a configurable number of IRQ lines. When
this device encounters sysbus devices that have been dynamically created and not
manually wired up, it dynamically connects them to its own pool of resources.

The machine model can then loop through all of these devices and create a guest
configuration (device tree) to make them visible to the guest.

471a9bc144 sysbus: Expose MMIO enumeration helper

of regions is device specific and internal information to the device model.

bus enumeration code can dynamically determine how many regions exist.

b797318666 sysbus: Expose IRQ enumeration helpers
Sysbus devices can get their IRQ lines connected to other devices. It is

This patch exposes helpers to make this information publicly accessible. We
will need it for the platform bus dynamic sysbus enumeration.

33cd52b5d7 sysbus: Make devices spawnable via -device
Now that we can properly map sysbus devices that haven't been connected to
something forcefully by C code, we can allow the -device command line option
to spawn them.

For machines that don't implement dynamic sysbus assignment in their board
files we add a new bool "has_dynamic_sysbus" to the machine class.
When that property is false (default), we bail out when we see dynamically
spawned sysbus devices, like we did before.

25bda50a0c hw/core/loader: implement address translation in uimage loader
Such address translation is needed when load address recorded in uImage
is a virtual address. When the actual load address is requested, return
untranslated address: user that needs the translated address can always
apply translation function to it and those that need it untranslated
don't need to do the inverse translation.

Add translation function pointer and its parameter to uimage_load
prototype. Update all existing users.

caad057bb6 smbios: Encode UUID according to SMBIOS specification
Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:

> Although RFC 4122 recommends network byte order for all fields, the PC
> industry (including the ACPI, UEFI, and Microsoft specifications) has
> consistently used little-endian byte encoding for the first three fields:
> time_low, time_mid, time_hi_and_version. The same encoding, also known as
> wire format, should also be used for the SMBIOS representation of the UUID.
>
> The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented
> as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.

The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b.

Change smbios_build_type_1_table() to encode the UUID as specified.

To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.

AcpiCpuHotplug_init --> acpi_cpu_hotplug_init
AcpiCpuHotplug_ops --> acpi_cpu_hotplug_ops
for better readability, just cleanup.

68a27b208a virtio-pci: fix migration for pci bus master
Current support for bus master (clearing OK bit) together with the need to
support guests which do not enable PCI bus mastering, leads to extra state in
VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version
migration for the case when guests use the device before setting DRIVER_OK.

Rip out this code, and replace it:
-   Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG
    so just drop it for latest machine type.
-   For compat machine types, set PCI_COMMAND if DRIVER_OK
    is set.

As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h
to a new common header.

2709f26395 well-defined listing order for machine types
Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of

  qemu-system-XXXX -M \?

This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:

  qemu_register_machine()
    type_register()
      type_register_internal()
        type_table_add()
          g_hash_table_insert()

and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):

  machine_parse()
    object_class_get_list(TYPE_MACHINE)
      object_class_foreach()
        g_hash_table_foreach()

The current order is a "random" one, for practical purposes, which is
annoying for users.

Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.

The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
  order,
- sorts machine types inside the same family in alphabetically decreasing
  order,
- sorts standalone machine types between each other in alphabetically
  increasing order.

After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.

scsi_cdb_length() does not return the length of the cdb, but
the transfersize encoded in the cdb. So rename it to scsi_cdb_xfer()
and also rename all other related functions to end with _xfer.

We can then add a new scsi_cdb_length() which actually does return the
length of the cdb.  With that DEBUG_SCSI can now display the correct
CDB buffer.

37f9e258b6 xen-hvm.c: Add support for Xen access to vmport
This adds synchronisation of the 6 vcpu registers (only 32bits of
them) that vmport.c needs between Xen and QEMU.

This is to avoid a 2nd and 3rd exchange between QEMU and Xen to
fetch and put these 6 vcpu registers used by the code in vmport.c
and vmmouse.c

The registers are passed in the new shared page provided by
HVM_PARAM_VMPORT_REGS_PFN.

Add new array to XenIOState that allows selection of current_cpu by
vcpu id.

Now pass XenIOState to handle_ioreq().

Add new routines regs_to_cpu(), regs_from_cpu(), and
handle_vmport_ioreq().

7797a73947 hmp: Remove "info pcmcia"
This command lists PCMCIA sockets and cards.  Only a few ARM boards
have sockets (akita, borzoi, connex, mainstone, spitz, terrier, tosa,
verdex, z2), the only card is the DSCM-1xxxx Hitachi Microdrive (qdev
"microdrive"), and it is only inserted during machine init, if ever.
So this command doesn't really tell anybody anything new so far.

Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged
by Coverity.  Has never been used, because there has never been code
to eject a PCMCIA card.

Not worth fixing & converting to QMP.  Remove it.

b591721909 sysbus: Use TYPE_DEVICE GPIO functionality
Re-implement the Sysbus GPIOs to use the existing TYPE_DEVICE
GPIO named framework. A constant string name is chosen to avoid
conflicts with existing unnamed GPIOs.

This unifies GPIOs are IRQs for sysbus devices and allows removal
of all Sysbus state for GPIOs.

Any existing and future-added functionality for GPIOs is now
also available for sysbus IRQs.

17a96a146c qdev: gpio: Define qdev_pass_gpios()
Allows a container to take ownership of GPIOs in a contained
device and automatically connect them as GPIOs to the container.

This prepares for deprecation of the SYSBUS IRQ functionality, which
has this feature. We push it up to the device level instead of sysbus
level. There's nothing sysbus specific about passing GPIOs to
containers so its a legitimate device-level generic feature.

4be746345f hw: Convert from BlockDriverState to BlockBackend, mostly
Device models should access their block backends only through the
block-backend.h API.  Convert them, and drop direct includes of
inappropriate headers.

Just four uses of BlockDriverState are left:

* The Xen paravirtual block device backend (xen_disk.c) opens images
  itself when set up via xenbus, bypassing blockdev.c.  I figure it
  should go through qmp_blockdev_add() instead.

* Device model "usb-storage" prompts for keys.  No other device model
  does, and this one probably shouldn't do it, either.

* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
  blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
  which has only the BlockDriverState.

* PC87312State has an unused BlockDriverState[] member.

The next two commits take care of the latter two.

Note that this has an user-visible side-effect: instead of reporting
"Xen is not supported for this target", QEMU binaries not supporting Xen
will report "xen accelerator does not exist".

As xen_available() always return 1 when CONFIG_XEN is enabled, we don't
need to set AccelClass.available anymore. xen_enabled() is not being
removed yet, but only because vl.c is still using it.

This also allows us to make xen_init() static.

1602651833 pc/vl: Add units-per-default-bus property
This patch adds the 'units_per_default_bus' property which
allows individual boards to declare their desired
index => (bus,unit) mapping for their default HBA, so that
boards such as Q35 can specify that its default if_ide HBA,
AHCI, only accepts one unit per bus.

This property only overrides the mapping for drives matching
the block_default_type interface.

This patch also adds this property to *all* past and present
Q35 machine types. This retroactive addition is justified
because the previous erroneous index=>(bus,unit) mappings
caused by lack of such a property were not utilized due to
lack of initialization code in the Q35 init routine.

Further, semantically, the Q35 board type has always had the
property that its default HBA, AHCI, only accepts one unit per
bus. The new code added to add devices to drives relies upon
the accuracy of this mapping. Thus, the property is applied
retroactively to reduce complexity of allowing IDE HBAs with
different units per bus.

Examples:

Prior to this patch, all IDE HBAs were assumed to use 2 units
per bus (Master, Slave). When using Q35 and AHCI, however, we
only allow one unit per bus.

-hdb foo.qcow2 would become index=1, or bus=0,unit=1.
-hdd foo.qcow2 would become index=3, or bus=1,unit=1.
-drive file=foo.qcow2,index=5 becomes bus=2,unit=1.

These are invalid for AHCI. They now become, under Q35 only:

-hdb foo.qcow2 --> index=1, bus=1, unit=0.
-hdd foo.qcow2 --> index=3, bus=3, unit=0.
-drive file=foo.qcow2,index=5 --> bus=5,unit=0.

The mapping is adjusted based on the fact that the default IF
for the Q35 machine type is IF_IDE, and units-per-default-bus
overrides the IDE mapping from its default of 2 units per bus
to just 1 unit per bus.

8e0a9320e9 scsi: Introduce scsi_req_cancel_async
Devices will call this function to start an asynchronous cancellation. The
bus->info->cancel will be called after the request is canceled.

Devices will probably need to track a separate TMF request that triggers this
cancellation, and wait until the cancellation is done before completing it. So
we store a notifier list in SCSIRequest and in scsi_req_cancel_complete we
notify them.

91cb1c9b56 virtio-scsi-dataplane: Code to run virtio-scsi on iothread
This implements the core part of dataplane feature of virtio-scsi.

A few fields are added in VirtIOSCSICommon to maintain the dataplane
status. These fields are managed by a new source file:
virtio-scsi-dataplane.c.

Most code in this file will run on an iothread, unless otherwise
commented as in a global mutex context, such as those functions to
start, stop and setting the iothread property.

Upon start, we set up guest/host event notifiers, in a same way as
virtio-blk does. The handlers then pop request from vring and call into
virtio-scsi.c functions to process it. So we need to make sure make all
those called functions work with iothread, too.

61e68b3fbd scsi: Optimize scsi_req_alloc
Zeroing sense buffer for each scsi request is not efficient, we can just
leave it uninitialized because sense_len is set to 0.

Move the implicitly zeroed fields to the end of the structure and use a
partial memset.

The explicitly initialized fields (by scsi_req_alloc or scsi_req_new)
are moved to the beginning of the structure, before sense buffer, to
skip the memset.

Also change g_malloc0 to g_slice_alloc.

b3ce84fea4 qdev: Move global validation to a single function
Currently GlobalProperty.not_used=false has multiple meanings:

* It may be a property for a hotpluggable device, which may or may not
  have been used by a device;
* It may be a machine-type-provided property, which may or may not have
  been used by a device.
* It may be a user-provided property that was actually not used by
  any device.

Simplify the logic by having two separate fields: 'user_provided' and
'used'. This allows the entire global property validation logic to be
contained in a single function, and allows more specific error messages.

5e5a94b605 block: Extract the block accounting code
The plan is to add new accounting metrics (latency, invalid requests, failed
requests, queue depth) and block.c is overpopulated so it will be better to work
in a separate module.

Moreover the long term plan is to have statistics in each of the BDS of the graph
for metrology purpose; this means that the device model statistics must move from
the topmost BDS to the device model.

So we need to decouple the statistic code from BlockDriverState.

This is another argument for the extraction of the code in a separate module.

e6043e92c2 xhci PCIe endpoint migration compatibility fix
Add back the PCIe config capabilities on XHCI cards in non-PCIe slots,
but only for machine types before 2.1.

This fixes a migration incompatibility in the XHCI PCI devices
caused by:
   058fdcf52c - xhci: add endpoint cap on express bus only

Note that in fixing it for compatibility with older QEMUs, it breaks
compatibility with existing QEMU 2.1's on older machine types.

The status before this patch was (if it used an XHCI adapter):
   machine type | source qemu
     any           pre-2.1     - FAIL
     any           2.1...      - PASS

With this patch:
   machine type | source qemu
     any           pre-2.1    - PASS
     pre-2.1       2.1...     - FAIL
     2.1           2.1...     - PASS

A test to trigger it is to add '-device nec-usb-xhci,id=xhci,addr=0x12'
to the command line.

8c46f7ec85 spapr_pci: map the MSI window in each PHB
On sPAPR, virtio devices are connected to the PCI bus and use MSI-X.
Commit cc943c36fa has modified MSI-X
so that writes are made using the bus master address space and follow
the IOMMU path.

Unfortunately, the IOMMU address space address space does not have an
MSI window: the notification is silently dropped in unassigned_mem_write
instead of reaching the guest... The most visible effect is that all
virtio devices are non-functional on sPAPR since then. :(

This patch does the following:
1) map the MSI window into the IOMMU address space for each PHB
   - since each PHB instantiates its own IOMMU address space, we
     can safely map the window at a fixed address (SPAPR_PCI_MSI_WINDOW)
   - no real need to keep the MSI window setup in a separate function,
     the spapr_pci_msi_init() code moves to spapr_phb_realize().

2) kill the global MSI window as it is not needed in the end

b7d1f77ada spapr: Locate RTAS and device-tree based on real RMA
We currently calculate the final RTAS and FDT location based on
the early estimate of the RMA size, cropped to 256M on KVM since
we only know the real RMA size at reset time which happens much
later in the boot process.

This means the FDT and RTAS end up right below 256M while they
could be much higher, using precious RMA space and limiting
what the OS bootloader can put there which has proved to be
a problem with some OSes (such as when using very large initrd's)

Fortunately, we do the actual copy of the device-tree into guest
memory much later, during reset, late enough to be able to do it
using the final RMA value, we just need to move the calculation
to the right place.

However, RTAS is still loaded too early, so we change the code to
load the tiny blob into qemu memory early on, and then copy it into
guest memory at reset time. It's small enough that the memory usage
doesn't matter.

ea87616d6c loader: Add load_image_size() to replace load_image()
A subsequent patch to ppc/spapr needs to load the RTAS blob into
qemu memory rather than target memory (so it can later be copied
into the right spot at machine reset time).

I would use load_image() but it is marked deprecated because it
doesn't take a buffer size as argument, so let's add load_image_size()
that does.

261265cc91 PPC: mac99: Move NVRAM to page boundary when necessary
When running KVM we have to adhere to host page boundaries for memory slots.
Unfortunately the NVRAM on mac99 is a 4k RAM hole inside of an MMIO flash
area.

So if our host is configured with 64k page size, we can't use the mac99 target
with KVM. This is a real shame, as this limitation is not really an issue - we
can easily map NVRAM somewhere else and at least Linux and Mac OS X use it
at their new location.

So in that emergency case when it's about failing to run at all and moving NVRAM
to a place it shouldn't be at, choose the latter.

This patch enables -M mac99 with KVM on 64k page size hosts.

2e14072f9e ppc: spapr-rtas - implement os-term rtas call
PAPR compliant guest calls this in absence of kdump. This finally
reaches the guest and can be handled according to the policies set by
higher level tools(like taking dump) for further analysis by tools like
crash.

Linux kernel calls ibm,os-term when extended property of os-term is set.
This makes sure that a return to the linux kernel is gauranteed.

a818a4b69d scsi-bus: Convert DeviceClass init to realize
Replace "init/destroy" with "realize/unrealize" in SCSIDeviceClass,
which has errp as a parameter. So all the implementations now use
error_setg instead of error_report for reporting error.

Also in scsi_bus_legacy_handle_cmdline, report the error when
initializing the if=scsi devices, before returning it, because in the
callee, error_report is changed to error_setg. And the callers don't
have the right locations (e.g. "-drive if=scsi").

9cb805fd26 cpus: Define callback for QEMU "nmi" command
This introduces an NMI (Non Maskable Interrupt) interface with
a single nmi_monitor_handler() method. A machine or a device can
implement it. This searches for an QOM object with this interface
and if it is implemented, calls it. The callback implements an action
required to cause debug crash dump on in-kernel debugger invocation.
The callback returns Error**.

This adds a nmi_monitor_handle() helper which walks through
all objects to find the interface. The interface method is called
for all found instances.

This adds support for it in qmp_inject_nmi(). Since no architecture
supports it at the moment, there is no change in behaviour.

This changes inject-nmi command description for HMP and QMP.

07fb61760c pc: hack for migration compatibility from QEMU 2.0
Changing the ACPI table size causes migration to break, and the memory
hotplug work opened our eyes on how horribly we were breaking things in
2.0 already.

The ACPI table size is rounded to the next 4k, which one would think
gives some headroom.  In practice this is not the case, because the user
can control the ACPI table size (each CPU adds 97 bytes to the SSDT and
8 to the MADT) and so some "-smp" values will break the 4k boundary and
fail to migrate.  Similarly, PCI bridges add ~1870 bytes to the SSDT.

This patch concerns itself with fixing migration from QEMU 2.0.  It
computes the payload size of QEMU 2.0 and always uses that one.
The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size
should always be enough; non-AML tables can change depending on the
configuration (especially MADT, SRAT, HPET) but they remain the same
between QEMU 2.0 and 2.1, so we only compute our padding based on the
sizes of the SSDT and DSDT.

Migration from QEMU 1.7 should work for guests that have a number of CPUs
other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140.  It was already
broken from QEMU 1.7 to QEMU 2.0 in the same way, though.

Even with this patch, QEMU 1.7 and 2.0 have two different ideas of
"-M pc-i440fx-2.0" when there are PCI bridges.  Igor sent a patch to
adopt the QEMU 1.7 definition.  I think distributions should apply
it if they move directly from QEMU 1.7 to 2.1+ without ever packaging
version 2.0.

1f4e6a069b virtio-scsi: fix with -M pc-i440fx-2.0
Right now starting a machine with virtio-scsi and a <= 2.0 machine type
fails with:

    qemu-system-x86_64: -device virtio-scsi-pci: Property .any_layout not found

This is because the any_layout bit was actually never set after
virtio-scsi was changed to support arbitrary layout for virtio buffers.

(This was just a cleanup and a preparation for virtio 1.0; no guest
actually checks the bit, but the new request parsing algorithms are
tested even with old guest).

f897bf751f virtio-blk: embed VirtQueueElement in VirtIOBlockReq
The memory allocation between hw/block/virtio-blk.c,
hw/block/dataplane/virtio-blk.c, and hw/virtio/dataplane/vring.c is
messy.  Structs are allocated in different files than they are freed in.
This is risky and makes memory leaks easier.

Embed VirtQueueElement in VirtIOBlockReq to reduce the amount of memory
allocation we need to juggle.  This also makes vring.c and virtio.c
slightly more similar.

abd764250f dataplane: do not free VirtQueueElement in vring_push()
VirtQueueElement is allocated in vring_pop() so it seems to make sense
that vring_push() should free it.  Alas, virtio-blk frees
VirtQueueElement itself in virtio_blk_free_request().

This patch solves a double-free assertion in glib's g_slice_free().

Rename vring_free_element() to vring_unmap_element() since it no longer
frees the VirtQueueElement.

352e8da743 qdev: correctly send DEVICE_DELETED for recursively-deleted devices
When a device is unparented (i.e. made completely hidden from management)
we want to send a DEVICE_DELETED event only if the device actually was
realized.  This avoids raising DEVICE_DELETED events when device_add
fails.

However, this does not work right for recursively-deleted
devices: the whole tree is _first_ unrealized, _then_ unparented.
Then device_unparent sees realized==false and fails to trigger
the event.  The solution is simply to move have_realized into
the DeviceState struct.  If device_add fails, we never set the
new field to true and DEVICE_DELETED is not sent.

Fixes qemu-iotests testcase 067 (broken by commit 5942a19, though that
commit in turn fixed a possible segfault in the same test).

dc80ca6cd6 virtio-blk: avoid qdev property definition duplication
It becomes unwiedly to duplicate all virtio-blk qdev property
definitions due to an #ifdef.  The C preprocessor syntax makes it a
little hard to resolve this cleanly but we can extract the #ifdef and
call a macro it defines later.

Avoiding duplication is important since it will only get worse when we
move the x-data-plane qdev property here too.  We'd have a combinatorial
explosion since x-data-plane has its own #ifdef.

We now have to pass the IRQ count to qemu_free_irqs(). We have so few

0f5d1d2a49 virtio: memory accessors for endian-ambivalent targets
This is the virtio-access.h header file taken from Rusty's "endian-ambivalent
targets using legacy virtio" patch. It introduces helpers that should be used
when accessing vring data or by drivers for data that contains headers.
The virtio config space is also target endian, but the current code already
handles that with the virtio_is_big_endian() helper. There is no obvious
benefit at using the virtio accessors in this case.

Now we have two distinct paths: a fast inline one for fixed endian targets,
and a slow out-of-line one for targets that define the new TARGET_IS_BIENDIAN
macro.

616a655219 virtio: add endian-ambivalent support to VirtIODevice
Some CPU families can dynamically change their endianness. This means we
can have little endian ppc or big endian arm guests for example. This has
an impact on legacy virtio data structures since they are target endian.
We hence introduce a new property to track the endianness of each virtio
device. It is reasonnably assumed that endianness won't change while the
device is in use : we hence capture the device endianness when it gets
reset.

We migrate this property in a subsection, after the device descriptor. This
means the load code must not rely on it until it is restored. As a consequence,
the vring sanity checks had to be moved after the call to vmstate_load_state().
We enforce paranoia by poisoning the property at the begining of virtio_load().

We currently have a virtio_is_big_endian() helper that provides the target
endianness to the virtio code. As of today, the helper returns a fixed
compile-time value. Of course, this will have to change if we want to

Let's move the TARGET_WORDS_BIGENDIAN bits out to a new helper and have
virtio_is_big_endian() implemented on top of it.

b8f5cfd682 pc: Move q35 compat props to PC_COMPAT_*
For each compat property on PC_Q35_COMPAT_*, there are only two
possibilities:

 * If the device is never instantiated when using a machine other than
   pc-q35, then the compat property can be safely added to
   PC_COMPAT_*;
 * If the device can be instantiated when using a machine other than
   pc-q35, that means the other machines also need the compat property
   to be set.

That means we don't need separate PC_Q35_COMPAT_* macros at all, today.

The hpet.hpet-intcap case is interesting: piix and q35 do have something
that emulates different defaults, but the machine-specific default is
applied _after_ compat_props are applied, by simply checking if the
property is zero (which is the real default on the hpet code).

The hpet.hpet-intcap=0x4 compat property can (should?) be applied to
piix too, because 0x4 was the default on both piix and q35 before the
hpet-intcap property was introduced.

Now, if one day we change the default HPET intcap on one of the PC
machine-types again, we may want to introduce PC_{Q35,I440FX}_COMPAT
macros. But while we don't need that, we can keep the code simple.

9a321e9234 spapr_pci: Use XICS interrupt allocator and do not cache interrupts in PHB
Currently SPAPR PHB keeps track of all allocated MSI (here and below
MSI stands for both MSI and MSIX) interrupt because
XICS used to be unable to reuse interrupts. This is a problem for
dynamic MSI reconfiguration which happens when guest reloads a driver
or performs PCI hotplug. Another problem is that the existing
implementation can enable MSI on 32 devices maximum
(SPAPR_MSIX_MAX_DEVS=32) and there is no good reason for that.

This makes use of new XICS ability to reuse interrupts.

This reorganizes MSI information storage in sPAPRPHBState. Instead of
static array of 32 descriptors (one per a PCI function), this patch adds
a GHashTable when @config_addr is a key and (first_irq, num) pair is
a value. GHashTable can dynamically grow and shrink so the initial limit
of 32 devices is gone.

This changes migration stream as @msi_table was a static array while new
@msi_devs is a dynamic hash table. This adds temporary array which is
used for migration, it is populated in "spapr_pci"::pre_save() callback
and expanded into the hash table in post_load() callback. Since
the destination side does not know the number of MSI-enabled devices
in advance and cannot pre-allocate the temporary array to receive
migration state, this makes use of new VMSTATE_STRUCT_VARRAY_ALLOC macro
which allocates the array automatically.

This resets the MSI configuration space when interrupts are released by
the ibm,change-msi RTAS call.

This fixed traces to be more informative.

This changes vmstate_spapr_pci_msi name from "...lsi" to "...msi" which
was incorrect by accident. As the internal representation changed,
thus bumps migration version number.

The current allocator returns IRQ numbers from a pool and does not
support IRQs reuse in any form as it did not keep track of what it
previously returned, it only keeps the last returned IRQ. Some use
cases such as PCI hot(un)plug may require IRQ release and reallocation.

This moves an allocator from SPAPR to XICS.

This switches IRQ users to use new API.

This uses LSI/MSI flags to know if interrupt is allocated.

4af88944d0 xics: Add flags for interrupts
The existing interrupt allocation scheme in SPAPR assumes that
interrupts are allocated at the start time, continously and the config
will not change. However, there are cases when this is not going to work
such as:

1. migration - we will have to have an ability to choose interrupt
numbers for devices in the command line and this will create gaps in
interrupt space.

2. PCI hotplug - interrupts from unplugged device need to be returned
back to interrupt pool, otherwise we will quickly run out of interrupts.

This replaces a separate lslsi[] array with a byte in the ICSIRQState
struct and defines "LSI" and "MSI" flags. Neither of these flags set
signals that the descriptor is not allocated and not in use.

9fc34ada7e spapr_pci_vfio: Add spapr-pci-vfio-host-bridge to support vfio
The patch adds a spapr-pci-vfio-host-bridge device type
which is a PCI Host Bridge with VFIO support. The new device
inherits from the spapr-pci-host-bridge device and adds an "iommu"
property which is an IOMMU id. This ID represents a minimal entity
for which IOMMU isolation can be guaranteed. In SPAPR architecture IOMMU
group is called a Partitionable Endpoint (PE).

Current implementation supports one IOMMU id per QEMU VFIO PHB. Since
SPAPR allows multiple PHB for no extra cost, this does not seem to
be a problem. This limitation may change in the future though.

Example of use:
Configure and Add 3 functions of a multifunctional device to QEMU:
(the NEC PCI USB card is used as an example here):
-device spapr-pci-vfio-host-bridge,id=USB,iommu=4,index=7 \
-device vfio-pci,host=4:0:1.0,addr=1.0,bus=USB,multifunction=true
-device vfio-pci,host=4:0:1.1,addr=1.1,bus=USB
-device vfio-pci,host=4:0:1.2,addr=1.2,bus=USB

where:
* index=7 is a QEMU PHB index (used as source for MMIO/MSI/IO windows
offset);
* iommu=4 is an IOMMU id which can be found in sysfs:
[aik@vpl2 ~]$ cd /sys/bus/pci/devices/0004:00:00.0/
[aik@vpl2 0004:00:00.0]$ ls -l iommu_group

9bb62a0702 spapr_iommu: Make in-kernel TCE table optional
POWER KVM supports an KVM_CAP_SPAPR_TCE capability which allows allocating
TCE tables in the host kernel memory and handle H_PUT_TCE requests
targeted to specific LIOBN (logical bus number) right in the host without
switching to QEMU. At the moment this is used for emulated devices only
and the handler only puts TCE to the table. If the in-kernel H_PUT_TCE
handler finds a LIOBN and corresponding table, it will put a TCE to
the table and complete hypercall execution. The user space will not be
notified.

Upcoming VFIO support is going to use the same sPAPRTCETable device class
so KVM_CAP_SPAPR_TCE is going to be used as well. That means that TCE
tables for VFIO are going to be allocated in the host as well.
However VFIO operates with real IOMMU tables and simple copying of
a TCE to the real hardware TCE table will not work as guest physical
to host physical address translation is requited.

So until the host kernel gets VFIO support for H_PUT_TCE, we better not
to register VFIO's TCE in the host.

This adds a place holder for KVM_CAP_SPAPR_TCE_VFIO capability. It is not
in upstream yet and being discussed so now it is always false which means
that in-kernel VFIO acceleration is not supported.

This adds a bool @vfio_accel flag to the sPAPRTCETable device telling
that sPAPRTCETable should not try allocating TCE table in the host kernel
for VFIO. The flag is false now as at the moment there is no VFIO.

This adds an vfio_accel parameter to spapr_tce_new_table(), the semantic
is the same. Since there is only emulated PCI and VIO now, the flag is set
to false. Upcoming VFIO support will set it to true.

This is a preparation patch so no change in behaviour is expected

3a3b8502e6 spapr: Fix RTAS token numbers
At the moment spapr_rtas_register() allocates a new token number for every
new RTAS callback so numbers are not fixed and depend on the number of
supported RTAS handlers and the exact order of spapr_rtas_register() calls.
These tokens are copied into the device tree and remain the same during
the guest lifetime.

When we start another guest to receive a migration, it calls
spapr_rtas_register() as well. If the number of RTAS handlers or their
order is different in QEMU on source and destination sides, the "/rtas"
node in the device tree will differ. Since migration overwrites the device
tree (as it overwrites the entire RAM), the actual RTAS config on
the destination side gets broken.

This defines global contant values for every RTAS token which QEMU
is using today.

This changes spapr_rtas_register() to accept a token number instead of
allocating one. This changes all users of spapr_rtas_register().

This changes XICS-KVM not to cache tokens registered with KVM as they
constant now.

This makes TOKEN_BASE global as RTAS_XXX use TOKEN_BASE as
a base. TOKEN_MAX is moved and renamed too and its value is changed
to the last token + 1. Boundary checks for token values are adjusted.

This reserves token numbers for "os-term" handlers and PCI hotplug
which we are working on.

c87b152072 pc & q35: Add new machine opt max-ram-below-4g
This is a pc & q35 only machine opt.

If you add enough PCI devices then all mmio for them will not fit
below 4G which may not be the layout the user wanted. This allows
you to increase the below 4G address space that PCI devices can use
(aka decrease ram below 4G) and therefore in more cases not have any
mmio that is above 4G.

For example using "-machine pc,max-ram-below-4g=2G" on the command
line will limit the amount of ram that is below 4G to 2G.

Note: this machine option cannot be used to increase the amount
of ram below 4G.

24d1eb33eb Add vhost_ops to vhost_dev struct and replace all relevant ioctls
Decouple vhost from the Linux kernel by introducing vhost_ops. The
intention is to provide different backends - a 'kernel' backend based on
the ioctl interface, and an 'user' backend based on a UNIX domain socket
and shared memory interface.

f57fcf7063 virtio-net: announce self by guest
It's hard to track all mac addresses and their configurations (e.g
vlan or ipv6) in qemu. Without this information, it's impossible to
build proper garp packet after migration. The only possible solution
to this is let guest (who knows all configurations) to do this.

So, this patch introduces a new readonly config status bit of virtio-net,
VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce
presence of its link through config update interrupt.When guest has
done the announcement, it should ack the notification through
VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new
feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by
Linux guest).

During load, a counter of announcing rounds is set so that after the vm is
running it can trigger rounds of config interrupts to notify the guest to build
and send the correct garps.

Note:
GCompareFunc(a, b) used by g_slist_insert_sorted() returns 'gint',
however it might be too small to fit difference between
2 addresses. So use 128bit to calculate the difference and normalize
result to -1/0/1 return values.

10b7e74bf2 pc: implement pc-dimm device abstraction
Each hotplug-able memory slot is a PCDIMMDevice.
A hot-add operation for a memory device:
- creates a new PCDIMMDevice and makes hotplug controller to map it into
  guest address space

Hotplug operations are done through normal device_add commands.
For migration case, all hotplugged memory devices on source should be
specified on target's command line using '-device' option with
properties set to the same values as on source.

To simplify review, patch introduces only PCDIMMDevice QOM skeleton that
will be extended by following patches to implement actual memory hotplug
and related functions.

vhost userspace needn't to handle vq's notification from guest,
so define dummy handle_output callback for all vqs of vhost-scsi.

In some corner cases(such as when handling vq's reset from VM), virtio-pci
still trys to handle pending virtio-scsi events, then object check failure
inside virtio_scsi_handle_event() for vhost-scsi can be triggered.

The issue can be reproduced by 'rmmod virtio-scsi', 'system sleep' or reboot
inside VM.
