0f2707e4e7 acpi: introduce AML composer aml_append()
Adds for dynamic AML creation, which will be used
for piecing ASL/AML primitives together and hiding
from user/caller details about how nested context
should be closed/packed leaving less space for
mistakes and necessity to know how AML should be
encoded, allowing user to concentrate on ASL
representation instead.

For example it will allow to create AML like this:

init_aml_allocator();
...
Aml *scope = aml_scope("PCI0")
Aml *dev = aml_device("PM")
    aml_append(dev, aml_name_decl("_ADR", aml_int(addr)))
aml_append(scope, dev);
...
free_aml_allocator();

ef546f1275 virtio: add feature checking helpers
Add a helper function for checking whether a bit is set in the guest
features for a vdev as well as one that works on a feature bit set.

Convert code that open-coded this: It cleans up the code and makes it
easier to extend the guest feature bits.

0cd09c3a6c virtio: feature bit manipulation helpers
Add virtio_{add,clear}_feature helper functions for manipulating a
feature bits variable. This has some benefits over open coding:
- add check that the bit is in a sane range
- make it obvious at a glance what is going on
- have a central point to change when we want to extend feature bits

Convert existing code manipulating features to use the new helpers.

virtio_set_features() like everybody else: We need to make sure
that bad features are masked out properly, which this function did
not do.

Fix applies only to new machine types starting

91a734a6fa acpi, ich9: Add unplug cb for ich9.
Memory and CPU hot unplug are both asynchronous procedures.
When the unplug operation happens, unplug request cb is called first.
And when guest OS finished handling unplug, unplug cb will be called
to do the real removal of device.

This patch adds hotunplug cb to ich9, which memory and CPU
hot unplug will use it.

25f8dd9659 qdev: Don't exit when running into bad -global
-global lets you set a nice booby-trap for yourself:

    $ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
    QEMU 2.1.94 monitor - type 'help' for more information
    (qemu) device_add usb-mouse
    Parameter 'usb_version' expects an int64 value or range
    $ echo $?
    1

Not nice.  Until commit 3196270 we even abort()ed.

The same error triggers if you manage to screw up a machine type's
compat_props.  To demonstrate, change HW_COMPAT_2_1's entry to

            .driver   = "usb-mouse",\
            .property = "usb_version",\
            .value    = "1", \

Then run

    $ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
    upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
    $ echo $?
    1

One of our creatively cruel error messages.

Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.

But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user.  Looks like this:

    $ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
    QEMU 2.1.94 monitor - type 'help' for more information
    (qemu) device_add usb-mouse
    Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
    (qemu)

This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().

You could argue that the error should make device_add fail.  Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.

grlib_apbuart_create() are helpers to create and realize GRLIB
devices.  Their only caller leon3_generic_hw_init() doesn't check for
failure.  Only the first can actually fail, and only when the caller
fails to set up a pointer property, which is a programming error.

Replace qdev_init() by qdev_init_nofail().

b0e5d90ebc dataplane: endianness-aware accesses
The vring.c code currently assumes that guest and host endianness match,
which is not true for a number of cases:

- emulating targets with a different endianness than the host
- bi-endian targets, where the correct endianness depends on the virtio
  device
- upcoming support for the virtio-1 standard mandates little-endian
  accesses even for big-endian targets and hosts

Make sure to use accessors that depend on the virtio device.

Note that dataplane now needs to be built per-target.

With simple exposure of MMFG, ioport window, mmio window and an IRQ line we
can successfully create a workable PCIe host bridge that can be mapped anywhere
and only needs to get described to the OS using whatever means it likes.

This patch implements such a "generic" host bridge. It handles 4 legacy IRQ
lines. MSIs need to be handled external to the host bridge.

This device is particularly useful for the "pci-host-ecam-generic" driver in

Now that vfio_put_base_device is called unconditionally at instance_finalize
time, it can be called twice if vfio_populate_device fails.  This works
but it is slightly harder to follow.

Change vfio_get_device to not touch the vbasedev struct until it will
definitely succeed, moving the vfio_populate_device call back to vfio-pci.
This way, vfio_put_base_device will only be called once.

95f7142abc virtio-blk: introduce multiread
this patch finally introduces multiread support to virtio-blk. While
multiwrite support was there for a long time, read support was missing.

The complete merge logic is moved into virtio-blk.c which has
been the only user of request merging ever since. This is required
to be able to merge chunks of requests and immediately invoke callbacks
for those requests. Secondly, this is required to switch to
direct invocation of coroutines which is planned at a later stage.

The following benchmarks show the performance of running fio with
4 worker threads on a local ram disk. The numbers show the average
of 10 test runs after 1 run as warmup phase.

27fb9688f9 pci: Split pcie_host_mmcfg_map()
The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.

So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.

6ac0d8d44c ich9: add disable_s3, disable_s4, s4_val properties
PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions.  Add such properties to the ICH9 chipset as well for the Q35
machine type.

S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.

The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.

These can be disabled via the cmdline:

  ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1

Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

3996e85c18 Xen: Use the ioreq-server API when available
The ioreq-server API added to Xen 4.5 offers better security than
the existing Xen/QEMU interface because the shared pages that are
used to pass emulation request/results back and forth are removed
from the guest's memory space before any requests are serviced.
This prevents the guest from mapping these pages (they are in a
well known location) and attempting to attack QEMU by synthesizing
its own request structures. Hence, this patch modifies configure
to detect whether the API is available, and adds the necessary
code to use the API if it is.

08f432aa3e virtio-serial: Don't keep a persistent copy of config space
The 'config' field in the VirtIOSerial structure keeps a copy of the virtio
console's config space as visible to the guest, that is to say, in guest
endianness.  This is fiddly to maintain, because on some targets, such as
powerpc, the "guest endianness" can change when a new guest OS boots.

In fact, there's no need to maintain such a guest view of config space -
instead we can reconstruct it from host-format data when it is accessed
with get_config.

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

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.

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.

When running in KVM mode, kvm_set_phys_mem() will silently
fail if registered MemoryRegion address/size is not page

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

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.

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.

eb5722801c sysbus: Add dynamic sysbus device search
Sysbus devices can be spawned by C code or dynamically via the command line.
In the latter case, we need to be able to find the dynamically created devices
to do things with them.

This patch adds a search helper that makes it easy to look for dynamically
spawned sysbus devices.

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.

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.

Effects on the x86_64 output:

1894df0281 scsi: Rename scsi_*_length() to scsi_*_xfer(), add scsi_cdb_length()
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.

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.

block driver thing.

Add a qemu extented register range to the standard vga mmio bar.
Right nowe there are two registers:  One readonly register returning the
size of the region (so we can easily add more registers there if needed)
and one endian control register, so guests (especially ppc) can flip
the framebuffer endianness as they need it.
