f1114c17ee mac_newworld: add via machine option to control mac99 VIA/ADB configuration
This option allows the VIA configuration to be controlled between 3
different possible setups: cuda, pmu-adb and pmu with USB rather than ADB
keyboard/mouse.

For the moment we don't do anything with the configuration except to pass
it to the macio device (the via-cuda parent) and also to the firmware via
the fw_cfg interface so that it can present the correct device tree.

The default is cuda which is the current default and so will have no
change in behaviour.

cb1efcf462 iommu: Add IOMMU index argument to notifier APIs
Add support for multiple IOMMU indexes to the IOMMU notifier APIs.
When initializing a notifier with iommu_notifier_init(), the caller
must pass the IOMMU index that it is interested in. When a change
happens, the IOMMU implementation must pass
memory_region_notify_iommu() the IOMMU index that has changed and
that notifiers must be called for.

IOMMUs which support only a single index don't need to change.
Callers which only really support working with IOMMUs with a single
index can use the result of passing MEMTXATTRS_UNSPECIFIED to
memory_region_iommu_attrs_to_index().

acd9575e59 aspeed_scu: Implement RNG register
The ASPEED SoCs contain a single register that returns random data when
read. This models that register so that guests can use it.

The random number data register has a corresponding control register,
however it returns data regardless of the state of the enabled bit, so
the model follows this behaviour.

When the qcrypto call fails we exit as the guest uses the random number
device to feed it's entropy pool, which is used for cryptographic
purposes.

f81804a52b hw/core/or-irq: Support more than 16 inputs to an OR gate
For the IoTKit MPC support, we need to wire together the
interrupt outputs of 17 MPCs; this exceeds the current
value of MAX_OR_LINES. Increase MAX_OR_LINES to 32 (which
should be enough for anyone).

The tricky part is retaining the migration compatibility for
existing OR gates; we add a subsection which is only used
for larger OR gates, and define it such that we can freely
increase MAX_OR_LINES in future (or even move to a dynamically
allocated levels[] array without an upper size limit) without
breaking compatibility.

95f875654a arm: Don't crash if user tries to use a Cortex-M CPU without an NVIC
The Cortex-M CPU and its NVIC are two intimately intertwined parts of
the same hardware; it is not possible to use one without the other.
Unfortunately a lot of our board models don't do any sanity checking
on the CPU type the user asks for, so a command line like
    qemu-system-arm -M versatilepb -cpu cortex-m3
will create an M3 without an NVIC, and coredump immediately.
In the other direction, trying a non-M-profile CPU in an M-profile
board won't blow up, but doesn't do anything useful either:
    qemu-system-arm -M lm3s6965evb -cpu arm926

Add some checking in the NVIC and CPU realize functions that the
user isn't trying to use an NVIC without an M-profile CPU or
an M-profile CPU without an NVIC, so we can produce a helpful
error message rather than a core dump.

38d81dafb3 hw/arm/armv7m: Remove unused armv7m_init() function
Remove the now-unused armv7m_init() function. This was a legacy from
before we properly QOMified ARMv7M, and it has some flaws:

 * it combines work that needs to be done by an SoC object (creating
   and initializing the TYPE_ARMV7M object) with work that needs to
   be done by the board model (setting the system up to load the ELF
   file specified with -kernel)
 * TYPE_ARMV7M creation failure is fatal, but an SoC object wants to
   arrange to propagate the failure outward
 * it uses allocate-and-create via qdev_create() whereas the current
   preferred style for SoC objects is to do creation in-place

Board and SoC models can instead do the two jobs this function
was doing themselves, in the right places and with whatever their
preferred style/error handling is.

only 4 GPIOs in this image.

ppc patch queue 2018-06-12

Here's another batch of ppc patches towards the 3.0 release.  There's
a fair bit here, because I've been working through my mail backlog
after a holiday.  There's not much of a central theme, amongst other
things we have:
    * ppc440 / sam460ex improvements
    * logging and error cleanups
    * 40p (PReP) bugfixes
    * Macintosh fixes and cleanups
    * Add emulation of the new POWER9 store-forwarding barrier
      instruction variant
    * Hotplug cleanups

265b578c58 object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalence
A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().

add_link() doesn't add a reference to the target object, while
set_link() does.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.

Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

30f79dc13f spapr_pci: Remove unhelpful pagesize warning
By default, the IOMMU model built into the spapr virtual PCI host bridge
supports 4kiB and 64kiB IOMMU page sizes.  However this can be overridden
which may be desirable to allow larger IOMMU page sizes when running a
guest with hugepage backing and passthrough devices.  For that reason a
warning was printed when the device wasn't configured to allow the pagesize
with which guest RAM is backed.

Experience has proven, however, that this message is more confusing than
useful.  Worse it sometimes makes little sense when the host-available page
sizes don't match those available on the guest, which can happen with
a POWER8 guest running on a POWER9 KVM host.

Long term we do want better handling to allow large IOMMU page sizes to be
used, but for now this parameter and warning don't really accomplish it.
So, remove the message, pending a better solution.

d638fd5c96 mos6522: move timer frequency initialisation to mos6522_reset
The 6522 VIA timer frequency cannot be set by altering registers within the
device itself and hence it is a fixed property of the machine.

Move the initialisation of the timer frequency to the mos6522 reset function
and ensure that any subclasses always call the parent reset function so that
it isn't required to store the timer frequency within vmstate_mos6522_timer
itself.

By moving the frequency initialisation to the device reset function then we
find that the realize function for both mos6522 and mos6522_cuda becomes
obsolete and can simply be removed.

2e3e5c7e92 cuda: embed mos6522_cuda device directly rather than using QOM object link
Examining the migration stream it can be seen that the mos6522 device state is
being stored separately rather than as part of the CUDA device which is
incorrect (and likely to cause issues if another mos6522 device is added to
the machine).

Resolve this by embedding the mos6522_cuda device directly within the CUDA
device rather than using a QOM object link to reference the device separately.

Note that we also bump the version in vmstate_cuda to reflect this change: this
isn't particularly important for the moment as the Mac machine migration isn't
100% reliable due to issues migrating the timebase under TCG.

VIO devices have an "irq" property that can be used by the sPAPR IRQ

new static IRQ allocator we want to introduce in sPAPR.

Unfortunately this commit didn't do the same for the 40p machine which broke

875bad3135 40p: remove pci_allow_0_address = true from 40p machine class
The Linux sandalfoot zImage has an initialisation process which resets the
VGA controller by setting all the BAR addresses to zero to access the VGA
ioports at their legacy addresses.

Unfortunately setting the framebuffer BAR to address 0 makes the framebuffer
memory overlap the internal VGA memory causing accesses to fail, and so
prevents the kernel from switching successfully to text mode.

Since OpenHackWare configures the framebuffer BAR address outside of the legacy
VGA internal memory space, remove pci_allow_0_address from the 40p machine class
which causes the BAR reprogramming to zero to fail and so the VGA internal
memory can be accessed correctly again.

introduced in 4e46dcdbd3 "PPC: Newworld: Add uninorth token register" is not
required, since the only register currently implemented is the uninorth hardware
version which is read-only.

Remove the token register implementation and instead return the uninorth
version corresponding to the hardware.

c173723f24 ide: introduce ide_transfer_start_norecurse
For the case where the end_transfer_func is also the caller of
ide_transfer_start, the mutual recursion can lead to unlimited
stack usage.  Introduce a new version that can be used to change
tail recursion into a loop, and use it in trace_ide_atapi_cmd_reply_end.

The ATAPI_INT_REASON_IO interrupt is raised when I/O starts, but in the
AHCI case ide_set_irq was actually called at the end of a mutual recursion.

There is code checking s->end_transfer_func and it was not taught about
ide_transfer_cancel.  We can just use ide_transfer_stop because
s->end_transfer_func is only ever called in the DRQ phase.

ide_transfer_cancel can then be removed, since it would just be
calling ide_transfer_halt.

956556e131 ahci: move PIO Setup FIS before transfer, fix it for ATAPI commands
The PIO Setup FIS is written in the PIO:Entry state, which comes before
the ATA and ATAPI data transfer states.  As a result, the PIO Setup FIS
interrupt is now raised before DMA ends for ATAPI commands, and tests have
to be adjusted.

This is also hinted by the description of the command header in the AHCI
specification, where the "A" bit is described as

    When ‘1’, indicates that a PIO setup FIS shall be sent by the device
    indicating a transfer for the ATAPI command.

and also by the description of the ACMD (ATAPI command region):

    The ATAPI command must be either 12 or 16 bytes in length. The length
    transmitted by the HBA is determined by the PIO setup FIS that is sent
    by the device requesting the ATAPI command.

QEMU, which conflates the "generator" and the "receiver" of the FIS into
one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

5694c7eacc ahci: fix PxCI register race
Fixes: https://bugs.launchpad.net/qemu/+bug/1769189

AHCI presently signals completion prior to the PxCI register being
cleared to indicate completion. If a guest driver attempts to issue
a new command in its IRQ handler, it might be surprised to learn there
is still a command pending.

In the case of Windows 10's boot driver, it will actually poll the IRQ
register hoping to find out when the command is done running -- which
will never happen, as there isn't a command running.

Fix this: clear PxCI in ahci_cmd_done and not in the asynchronous BH.
Because it now runs synchronously, we don't need to check if the command
is actually done by spying on the ATA registers. We know it's done.

    Specification Version 1.10. Therefore, cards that are
    compatible with earlier versions of the spec do not support
    it. The host shall check the "SD_SPEC" field in the SCR
    register to recognize what version of the spec the card
    complies with before using CMD6. It is mandatory for SD
    memory card of Ver1.10 to support CMD6.

    4.3.11 High-Speed mode (25MB/sec interface speed)

    Though the Rev 1.01 SD memory card supports up to 12.5MB/sec
    interface speed, the speed of 25MB/sec is necessary to support
    increasing performance needs of the host and because of memory
    size which continues to grow.
    To achieve 25MB/sec interface speed, clock rate is increased to
    50MHz and CLK/CMD/DAT signal timing and circuit conditions are
    reconsidered and changed from Physical Layer Specification
    Version 1.01.

    4.3.12 Command system (This chapter is newly added in version 1.10)

    SD commands CMD34-37, CMD50, CMD57 are reserved for SD command
    system expansion via the switch command.
    [These commands] will be considered as illegal commands (as
    defined in revision 1.01 of the SD physical layer specification).

The SWITCH_FUNCTION is implemented since the first commit, a1bb27b1e9.

The 25MB/sec High-Speed mode was already updated in d7ecb86752.

The current implementation does not implements CMD34-37, CMD50 and
CMD57, thus these commands already return ILLEGAL.

With this patch, the SCR register now matches the description of the header:

 * SD Memory Card emulation as defined in the "SD Memory Card Physical
 * layer specification, Version 1.10."

Fix this by skipping the registers banked by GICR.

Also for migration compatibility if the migration source (old version

we shift the data of PPI to get the right data for SPI.

2b1dbd0d72 vfio/quirks: Enable ioeventfd quirks to be handled by vfio directly
With vfio ioeventfd support, we can program vfio-pci to perform a
specified BAR write when an eventfd is triggered.  This allows the
KVM ioeventfd to be wired directly to vfio-pci, entirely avoiding
userspace handling for these events.  On the same micro-benchmark
where the ioeventfd got us to almost 90% of performance versus
disabling the GeForce quirks, this gets us to within 95%.

c958c51d2e vfio/quirks: ioeventfd quirk acceleration
The NVIDIA BAR0 quirks virtualize the PCI config space mirrors found
in device MMIO space.  Normally PCI config space is considered a slow
path and further optimization is unnecessary, however NVIDIA uses a
register here to enable the MSI interrupt to re-trigger.  Exiting to
QEMU for this MSI-ACK handling can therefore rate limit our interrupt
handling.  Fortunately the MSI-ACK write is easily detected since the
quirk MemoryRegion otherwise has very few accesses, so simply looking
for consecutive writes with the same data is sufficient, in this case
10 consecutive writes with the same data and size is arbitrarily
chosen.  We configure the KVM ioeventfd with data match, so there's
no risk of triggering for the wrong data or size, but we do risk that
pathological driver behavior might consume all of QEMU's file
descriptors, so we cap ourselves to 10 ioeventfds for this purpose.

In support of the above, generic ioeventfd infrastructure is added
for vfio quirks.  This automatically initializes an ioeventfd list
per quirk, disables and frees ioeventfds on exit, and allows
ioeventfds marked as dynamic to be dropped on device reset.  The
rationale for this latter feature is that useful ioeventfds may
depend on specific driver behavior and since we necessarily place a
cap on our use of ioeventfds, a machine reset is a reasonable point
at which to assume a new driver and re-profile.

f548222c24 migration: introduce decompress-error-check
QEMU 3.0 enables strict check for compression & decompression to
make the migration more robust, that depends on the source to fix
the internal design which triggers the unexpected error conditions

To make it work for migrating old version QEMU to 2.13 QEMU, we
introduce this parameter to disable the error check on the
destination which is the default behavior of the machine type
which is older than 2.13, alternately, the strict check can be
enabled explicitly as followings:
      -M pc-q35-2.11 -global migration.decompress-error-check=true

7e57b82ec3 ipmi: Use proper struct reference for KCS vmstate
The vmstate for isa_ipmi_kcs was referencing into the kcs structure,
instead create a kcs structure separate and use that.

There were also some issues in the state transfer.  The inlen field
was not being transferred, so if a transaction was in process during
the transfer it would be messed up.  And the use_irq field was
transferred, but that should come from the configuration.

To fix this, the new VMS_VSTRUCT macros are used so the exact
version of the structure can be specified, depending on what
version was being received.  So an upgrade should work for KCS.

dfb6578d69 xen-hvm: stop faking I/O to access PCI config space
This patch removes the current hackery where IOREQ_TYPE_PCI_CONFIG
requests are handled by faking PIO to 0xcf8 and 0xcfc and replaces it
with direct calls to pci_host_config_read/write_common().
Doing so necessitates mapping BDFs to PCIDevices but maintaining a simple
QLIST in xen_device_realize/unrealize() will suffice.

NOTE: whilst config space accesses are currently limited to
      PCI_CONFIG_SPACE_SIZE, this patch paves the way to increasing the
      limit to PCIE_CONFIG_SPACE_SIZE when Xen gains the ability to
      emulate MCFG table accesses.

04a8f72e87 xen/hvm: correct reporting of modified memory under physmap during migration
When global_log_dirty is enabled VRAM modification tracking never
worked correctly. The address that is passed to xen_hvm_modified_memory()
is not the effective PFN but RAM block address which is not the same
for VRAM.

We need to make a translation for this address into PFN using
physmap. Since there is no way to access physmap properly inside
xen_hvm_modified_memory() let's make it a global structure.

acpi_data_push uses g_array_set_size to resize the memory size. If there
is no enough contiguous memory, the address will be changed. So previous
pointer could not be used any more. It must update the pointer and use
the new one.

Also, previous codes wrongly use le32 conversion of iort->node_offset
for subsequent computations that will result incorrect value if host is
not litlle endian. So use the non-converted one instead.

Coverity found that the string return by 'object_get_canonical_path' was not
being freed at two locations in the model (CID 1391294 and CID 1391293) and
also that a memset was being called with a value greater than the max of a byte
on the second argument (CID 1391286). This patch corrects this by adding the
freeing of the strings and also changing to memset to zero instead on
descriptor unaligned errors.

60b8fe49cc arm: fix qemu crash on startup with -bios option
When QEMU is started with following CLI
 -machine virt,gic-version=3,accel=kvm -cpu host -bios AAVMF_CODE.fd
it crashes with abort at
 accel/kvm/kvm-all.c:2164:
 KVM_SET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c665: Invalid argument

Which is caused by implicit dependency of kvm_arm_gicv3_reset() on
arm_gicv3_icc_reset() where the later is called by CPU reset
reset callback.

However commit:
 3b77f6c arm/boot: split load_dtb() from arm_load_kernel()
broke CPU reset callback registration in case

  arm_load_kernel()
      ...
      if (!info->kernel_filename || info->firmware_loaded)

branch is taken, i.e. it's sufficient to provide a firmware
or do not provide kernel on CLI to skip cpu reset callback
registration, where before offending commit the callback
has been registered unconditionally.

Fix it by registering the callback right at the beginning of
arm_load_kernel() unconditionally instead of doing it at the end.

NOTE:
 we probably should eliminate that dependency anyways as well as
 separate arch CPU reset parts from arm_load_kernel() into CPU
 itself, but that refactoring that I probably would have to do
 anyways later for CPU hotplug to work.

38ab74e7ca tpm: extend TPM emulator with state migration support
Extend the TPM emulator backend device with state migration support.

The external TPM emulator 'swtpm' provides a protocol over
its control channel to retrieve its state blobs. We implement
functions for getting and setting the different state blobs.
In case the setting of the state blobs fails, we return a
negative errno code to fail the start of the VM.

Since we have an external TPM emulator, we need to make sure
that we do not migrate the state for as long as it is busy
processing a request. We need to wait for notification that
the request has completed processing.

765c942908 hw/display: add new bochs-display device
After writing up the virtual mdev device emulating a display supporting
the bochs vbe dispi interface (mbochs.ko) and seeing how simple it
actually is I've figured that would be useful for qemu too.

So, here it is, -device bochs-display.  It is basically -device VGA
without legacy vga emulation.  PCI bar 0 is the framebuffer, PCI bar 2
is mmio with the registers.  The vga registers are simply not there
though, neither in the legacy ioport location nor in the mmio bar.
Consequently it is PCI class DISPLAY_OTHER not DISPLAY_VGA.

So there is no text mode emulation, no weird video modes (planar,
256color palette), no memory window at 0xa0000.  Just a linear
framebuffer in the pci memory bar.  And the amount of code to emulate
this (and therefore the attack surface) is an order of magnitude smaller
when compared to vga emulation.

Compatibility wise it works with OVMF (latest git master).
The bochs-drm.ko linux kernel module can handle it just fine too.
So UEFI guests should not see any functional difference to VGA.
