67736a25f8 ARM: virt: Don't generate RTC ACPI device when using UEFI
When booting the VM with UEFI, UEFI takes ownership of the RTC hardware.
While UEFI can use libfdt to disable the RTC device node in the DTB that
it passes to the OS, it cannot modify AML. Therefore, we won't generate
the RTC ACPI device at all when using UEFI.

dc3b89ef87 xlnx-zynqmp: Add support for high DDR memory regions
The Xilinx ZynqMP SoC and EP108 board supports three memory regions:
 - A 2GB region starting at 0
 - A 32GB region starting at 32GB
 - A 256GB region starting at 768GB

This patch adds support for the first two memory regions, which is
automatically created based on the size specified by the QEMU memory
command line argument.

On hardware the physical memory region is one continuous region, it is then
mapped into the three different regions by the DDRC. As we don't model the
DDRC this is done at startup by QEMU. The board creates the memory region and
then passes that memory region to the SoC. The SoC then maps the memory
regions.

dced4d2fcb xen-hvm: Clean up xen_hvm_init() error handling
xen_hvm_init() returns -1 without cleaning up on some errors (harmless
long as the caller exit()s on error), dies with hw_error() on others.
hw_error() isn't approprate here.  Clean up to exit() on all errors.

ac0487e1d2 xenfb.c: avoid expensive loops when prod <= out_cons
If the frontend sets out_cons to a value higher than out_prod, it will
cause xenfb_handle_events to loop about 2^32 times. Avoid that by using
better checks at the beginning of the function.

193227f9e5 error: Use error_report_err() instead of monitor_printf()
Both error_report_err() and monitor_printf() print to the same
destination when monitor_printf() is used correctly, i.e. within an
HMP monitor.  Elsewhere, monitor_printf() does nothing, while
error_report_err() reports to stderr.

Most changed functions are HMP command handlers.  These should only
run within an HMP monitor.  The one exception is bdrv_password_cb(),
which should also only run within an HMP monitor.

Four command handlers prefix the error message with the command name:
balloon, migrate_set_capability, migrate_set_parameter, migrate.
Pointless, drop.

Unlike monitor_printf(), error_report_err() uses the error whole
instead of just its message obtained with error_get_pretty().  This
avoids suppressing its hint (see commit 50b7b00).  Example:

    (qemu) device_add ivshmem,id=666
    Parameter 'id' expects an identifier
    Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.
    Try "help device_add" for more information

675463d9b6 isa: Clean up inappropriate hw_error()
isa_bus_irqs(), isa_create() and isa_try_create() call hw_error() when
passed a null bus.  Use of hw_error() has always been questionable,
because these are used only during machine initialization, and
printing CPU registers isn't useful there.

Since the previous commit, passing a null bus is a programming error.
Drop the hw_error() and simply let it crash.

d10e54329b isa: Clean up error handling around isa_bus_new()
We can have at most one ISA bus.  If you try to create another one,
isa_bus_new() complains to stderr and returns null.

isa_bus_new() is called in two contexts, machine's init() and device's
realize() methods.  Since complaining to stderr is not proper in the
latter context, convert isa_bus_new() to Error.

Machine's init():

* mips_jazz_init(), called from the init() methods of machines
  "magnum" and "pica"

* mips_r4k_init(), the init() method of machine "mips"

* pc_init1() called from the init() methods of non-q35 PC machines

* typhoon_init(), called from clipper_init(), the init() method of
  machine "clipper"

These callers always create the first ISA bus, hence isa_bus_new()
can't fail.  Simply pass &error_abort.

Device's realize():

* i82378_realize(), of PCI device "i82378"

* ich9_lpc_realize(), of PCI device "ICH9-LPC"

* pci_ebus_realize(), of PCI device "ebus"

* piix3_realize(), of PCI device "pci-piix3", abstract parent of
  "PIIX3" and "PIIX3-xen"

* piix4_realize(), of PCI device "PIIX4"

* vt82c686b_realize(), of PCI device "VT82C686B"

Propagate the error.  Note that these devices are typically created
only by machine init() methods with qdev_init_nofail() or similar.  If
we screwed up and created an ISA bus before that call, we now give up
right away.  Before, we'd hobble on, and typically die in
isa_bus_irqs().  Similar if someone finds a way to hot-plug one of
these critters.

platform_bus_map_irq() and platform_bus_map_mmio() use hw_error() to
fail.  They run in machine_init_done_notifiers, via
platform_bus_init_notify() and link_sysbus_device().  Printing CPU
registers is not helpful there.

Replace hw_error() by error_report(); exit(1).  If these are
programming errors, it should be replaced by an assertion instead.

While there, observe that both functions always return 0, and
link_sysbus_device() ignores the return value.  Change them to void.

7b55044f9d hw/arm/virt: Fix property "gic-version" error handling
virt_set_gic_version() calls exit(1) when passed an invalid property
value.  Property setters are not supposed to do that.  Screwed up in
commit b92ad39.  Harmless, because the property belongs to a machine.
Set an error object instead.

9280eb34de raven: Mark use of hw_error() in realize() FIXME
Device realize() methods aren't supposed to call hw_error(), they
should set an error and fail cleanly.  Blindly doing that would be
easy enough, but then realize() would fail without undoing its side
effects.  Just mark it FIXME for now.

84a3a53cf6 omap: Don't use hw_error() in device init() methods
Device init() methods aren't supposed to call hw_error(), they should
report the error and fail cleanly.  Do that.

The errors are all device misconfiguration.  All callers use
qdev_init_nofail(), so this patch merely converts hw_error() crashes
into &error_abort crashes.  Improvement, because now it crashes closer
to where the misconfiguration bug would be, and a few more bad
examples of hw_error() use are gone.

When processing NCQ commands, AHCI device emulation prepares a
NCQ transfer object; To which an aio control block(aiocb) object
is assigned in 'execute_ncq_command'. In case, when the NCQ
command is invalid, the 'aiocb' object is not assigned, and NCQ
transfer object is left as 'used'. This leads to a use after
free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
Reset NCQ transfer object to 'unused' to avoid it.

fc9f38c3c0 pseries: Restructure class_options functions
Currently each of the *_class_options() functions for the pseries-2.1 ..
pseries-2.5 machine types are standalone.  This will become harder to
maintain as new versions are added.

This patch restructures them similarly to x86 where each function calls
the one from the next version, then overrides anything necessary for
compatibility with the specific version and older.

The default behaviour - that for the most recent machine are set up in
the base class initializer spapr_machine_class_init().  Previously it had
some things set up to default to older behaviour with the more recent
machines overriding it.

5013c54746 pseries: DEFINE_SPAPR_MACHINE
At the moment all the class_init functions and TypeInfo structures for the
various versioned pseries machine types are open-coded.  As more versions
are created this is getting increasingly clumsy.

This patch borrows the approach used in PC, using a DEFINE_SPAPR_MACHINE()
macro to construct most of the boilerplate from simpler 'class_options' and
'instance_options' functions.

This patch makes a small semantic change - the versioned machine types are
now registered through machine_init() instead of type_init().  Since the
new way is how PC already did it, I'm assuming that's correct.

The instance_init() functions for several of the pseries-x.y versioned
machine types explicitly call spapr_machine_initfn().  But that's the
instance_init function for the common parent of all those machine types,
so will already have been called beforehand by the QOM infrastructure.

1c5f29bbc8 pseries: Rearrange versioned machine type code
hw/ppc/spapr.c has a number of definitions related to the various versioned
machine types ("pseries-2.1" .. "pseries-2.5") it defines.  These are
mostly arranged by type of function first, then machine version second, and
it's not consistent about whether it goes in increasing or decreasing
version order.

This rearranges the code to keep all the definitions for a particular
machine version together, and arrange then consistently in order most
recent to least recent.

This brings us closer to matching the way PC does things, and makes later
cleanups easier to follow.

Apart from adding some comments marking each section, this is a pure
mechanical rearrangement with no semantic changes.

  VMXNET3_WRITE_BAR1_REG(adapter, VMXNET3_REG_CMD, VMXNET3_CMD_GET_DID_LO);
  lo =  VMXNET3_READ_BAR1_REG(adapter, VMXNET3_REG_CMD);

  VMXNET3_WRITE_BAR1_REG(adapter, VMXNET3_REG_CMD, VMXNET3_CMD_GET_DID_HI);
  high =  VMXNET3_READ_BAR1_REG(adapter, VMXNET3_REG_CMD);
  pr_info("vmxnet3 DID lo: 0x%x, high: 0x%x\n", lo, high);

The kernel log will have something like the following message:

  [ 7005.111170] vmxnet3 DID lo: 0x7b0, high: 0x1

fde58177aa net/vmxnet3: return 1 on device activation failure
When reading device status, 0 means device is successfully
activated and 1 means error.

This behavior can be observed by the following steps:

1) run a Linux distro on esxi server (5.5+)
2) modify vmxnet3 Linux driver to give it an invalid
   address to 'adapter->shared_pa' which is the
   shared memory for guest/host communication

This will trigger device activation failure and kernel
log will have the following message:

   [ 7138.403256] vmxnet3 0000:03:00.0 eth1: Failed to activate dev: error 1

So return 1 on device activation failure instead of -1;

aa4a3dce1c net: vmxnet3: avoid memory leakage in activate_device
Vmxnet3 device emulator does not check if the device is active
before activating it, also it did not free the transmit & receive
buffers while deactivating the device, thus resulting in memory
leakage on the host. This patch fixes both these issues to avoid
host memory leakage.

71c2f5b9b3 net/vmxnet3: fix debug macro pattern for vmxnet3
Vmxnet3 uses the following debug macro style:

 #ifdef SOME_DEBUG
 #  define debug(...) do{ printf(...); } while (0)
 # else
 #  define debug(...) do{ } while (0)
 #endif

If SOME_DEBUG is undefined, then format string inside the
debug macro will never be checked by compiler. Code is
likely to break in the future when SOME_DEBUG is enabled
 because of lack of testing. This patch changes this
to the following:

 #define debug(...) \
  do { if (SOME_DEBUG_ENABLED) printf(...); } while (0)

f070efa8d9 hw/i386: fill in the CENTURY field of the FADT (FACP) ACPI table
The ACPI specification (minimally versions 1.0b through 6.0) define the
FADT.CENTURY field as:

  The RTC CMOS RAM index to the century of data value (hundred and
  thousand year decimals). If this field contains a zero, then the RTC
  centenary feature is not supported. If this field has a non-zero value,
  then this field contains an index into RTC RAM space that OSPM can use
  to program the centenary field.

The x86 targets generate ACPI payload, emulate an RTC
(CONFIG_MC146818RTC), and that RTC supports the "centenary feature" (see
occurrences of RTC_CENTURY in cmos_ioport_write() and cmos_ioport_read()
in "hw/timer/mc146818rtc.c".)

However, FADT.CENTURY is left at zero currently:

  [06Ch 0108   1]            RTC Century Index : 00

which -- according to analysis done by Ruiyu Ni at Intel -- should cause
Linux and Windows 8+ to think the RTC centenary feature is unavailable,
and cause Windows 7 to (incorrectly) assume that the offset to use is
constant 0x32. (0x32 happens to be the right value on QEMU, but Windows 7
is wrong to assume anything at all).

Exposing the right nonzero offset in FADT.CENTURY informs Linux and
Windows 8+ about the right capabilities of the hardware, plus it retrofits
our FADT to Windows 7's behavior.

Regression tested with the following guests (all UEFI installs):
- i386 Q35: Fedora 21 ("Fedlet" edition)
- x86_64:
  - i440fx:
    - Fedora 21
    - RHEL 6 and 7
    - Windows 7 and 10
    - Windows Server 2008 R2 and 2012 R2
  - Q35:
    - Fedora 22
    - Windows 8.1

c8e6c93857 nvdimm: fix header pointer in nvdimm_build_nfit()
In the current nvdimm_build_nfit(), the pointer 'header' initially equals
to table_data->data + table_data->len. However, the following
g_array_append_vals(table_data, structures->data, structures->len)
may resize and relocate table_data->data[]. Therefore, the usage of 'header'
afterwards may be illegal.

This patch fixes this issue by storing an offset within table_data->data[]
(rather than an address) in 'header'.

4083733db5 ui/curses: Fix color attribute of monitor for curses
Current text_console_update() writes totally broken color attributes
to console_write_ch(). The format now is writing,

[WRONG]
	bold << 21 | fg << 12 | bg << 8 | char
	fg == 3bits curses color number
	bg == 3bits curses color number

I can't see this format is where come from. Anyway, this doesn't work
at all.

What curses expects is actually (and vga.c is using),

[RIGHT]
	bold << 21 | bg << 11 | fg << 8 | char
	fg == 3bits vga color number
	bg == 3bits vga color number

And curses set COLOR_PAIR() up to match this format, and curses's
chtype. I.e,

	bold | color_pair | char
	color_pair == (bg << 3 | fg)

To fix, this simply uses VGA color number everywhere except curses.c
internal. Then, convert it to above [RIGHT] format to write by
console_write_ch(). And as bonus, this reduces to expose curses define
to other parts (removes COLOR_* from console.c).

[Tested the first line is displayed as white on blue back for monitor
in curses console]

087462c773 ohci: clear pending SOF on suspend
On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.

On suspend, if a SOF interrupt is raised between the stop of the
device processing and the change of the device internal state to
OHCI_USB_SUSPEND (QEMU stops SOF timer on this state change), this
interrupt is never acknowledged.

This patch clears pending SOF interrupt on OHCI_USB_SUSPEND setting.

Some details:

- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
  only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
  So if this interrupt happens and the driver is not in this state,
  the function is called again and again, moving the system to a
  CPU starvation.

- ohci_rh_suspend(): the function stop the operation and acknowledge
  pending interrupts (but doesn't disable it). Later in the function,
  the device is moved to OHCI_SUSPEND_STATE, and the driver to
  OHCI_RH_SUSPENDED. If between the moment when the interrupt is
  acknowledged and the moment when the device is suspended a new
  interrupt is raised, it will be never acknowledged because the
  driver is now not in OHCI_RH_RUNNING state.

fd0a10cd20 ohci: delay first SOF interrupt
On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.

This does not happen on real hardware because real hardware never send
interrupt immediately after the controller has been moved to OPERATION state.

This patch tries to delay the first SOF interrupt to let driver exits from
the critical section (which is not protected against interrupts...)

Some details:

- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
  only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
  So if this interrupt happens and the driver is not in this state,
  the function is called again and again, moving the system to a
  CPU starvation.

- ohci_rh_resume(): the driver re-enables operation with OHCI_USB_OPER.
  In QEMU this start the SOF timer and QEMU starts to send IRQs. As
  the driver is not in OHCI_STATE_RUNNING and not protected against IRQ,
  the ohci_irq() can be called and the driver never moved to
  OHCI_STATE_RUNNING.

71042cffc0 9pfs: remove dead code
Some structures in virtio-9p.h have been unused since 2011 when relevant
functions switched to use coroutines.

The declaration of pdu_packunpack and function do_pdu_unpack are

4b3a4f2d45 virtio-9p: use accessor to get thread_pool
The aio_context_new() function does not allocate a thread pool. This is
deferred to the first call to the aio_get_thread_pool() accessor. It is
hence forbidden to access the thread_pool field directly, as it may be
NULL. The accessor *must* be used always.

439e2a6e10 acpi: aml: add helper for Opcode Arg2 Arg2 [Dst] AML pattern
Currently AML API doesn't compose terms in form of
following pattern:

   Opcode Arg2 Arg2 [Dst]

but ASL used in piix4/q35 DSDT ACPI tables uses that
form, so for clean conversion of it, AML API should
be able to handle an optional 'Dst' argumet used there.

Since above pattern is used by arithmetic/bit ops,
introduce helper that they could reuse.
It reduces code duplication in existing 5 aml_foo()
functions and also will prevent more duplication
when exiting functions are extended to support
optional 'Dst' argument.

772863954c nvdimm acpi: build ACPI nvdimm devices
NVDIMM devices is defined in ACPI 6.0 9.20 NVDIMM Devices

There is a root device under \_SB and specified NVDIMM devices are under the
root device. Each NVDIMM device has _ADR which returns its handle used to
associate MEMDEV structure in NFIT

Currently, we do not support any function on _DSM, that means, NVDIMM
label data has not been supported yet

87252e1b61 nvdimm acpi: build ACPI NFIT table
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)

Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info

- MEM DEV structure, it has the @handle which is used to associate specified
  ACPI NVDIMM  device we will introduce in later patch.
  Also we can happily ignored the memory device's interleave, the real
  nvdimm hardware access is hidden behind host

- DCR structure, it defines vendor ID used to associate specified vendor
  nvdimm driver. Since we only implement PMEM mode this time, Command
  window and Data window are not needed

The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100  -object \
memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \
nvdimm,memdev=mem1,id=nv1

It is disabled on default

cannot find any documentation that suggests the controller should
behave in this way, the error code doesn't make sense (command index
error is defined for the case where the index in a response does not
match that of the issued command), and in at least one case (CMD23
issued by UEFI on Raspberry Pi 2), actual hardware does not do this.

6890a695d9 sd: sdhci: Delete over-zealous power check
This check was conditionalising SD card operation on the card being
powered by the SDHCI host controller. It is however possible
(particularly in embedded systems) for the power control of the SD card
to be managed outside of SDHCI. This can be as trivial as hard-wiring
the SD slot VCC to a constant power-rail.

This means the guest SDHCI can validly opt-out of the SDHCI power
control feature while still using the card. So delete this check to
allow operation of the card with SDHCI power control.

This is needed for at least Xilinx Zynq and Raspberry Pi, and
also makes Freescale i.MX25 work for me. The digilent Zybo board
has a public schematic which shows SD VCC hardwiring:

15eafc2e60 kvm: x86: add support for KVM_CAP_SPLIT_IRQCHIP
This patch adds support for split IRQ chip mode. When
KVM_CAP_SPLIT_IRQCHIP is enabled:

    1.) The PIC, PIT, and IOAPIC are implemented in userspace while
    the LAPIC is implemented by KVM.

    2.) The software IOAPIC delivers interrupts to the KVM LAPIC via
    kvm_set_irq. Interrupt delivery is configured via the MSI routing
    table, for which routes are reserved in target-i386/kvm.c then
    configured in hw/intc/ioapic.c

    3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI,
    which is handled in target-i386/kvm.c and relayed to the software
    IOAPIC via ioapic_eoi_broadcast.

952970ba56 vmw_pvscsi: Introduce 'x-old-pci-configuration' backword compatability property
Following the previous patches, which introduced various changes in
pvscsi's pci configuration space (device subsystem id and revision, msi
offset), this patch introduces a boolean property
'x-old-pci-configuration' to pvscsi.

Its default value is false, exposing the above changes in the pci config
space.

Setting 'x-old-pci-configuration' to 'on' preserves the old behavior,
which allows migration to older versions.

The IMX_CCM class is now the base abstract class that is used by EPIT

IMX31_CCM class is the concrete class implementing CCM for i.MX31 SOC.

For now the i.MX25 continues to use the i.MX31 CCM implementation.

9de46a0aa3 i.MX: Fix i.MX31 default/reset configuration

instead of the CKIL plus the FPM multiplier.

We change the CCMR reg reset value to match linux expected config.

Behaviour of emulated devices should not depend on the endianness
of the CPU, so avoid using the endian-dependent load and store
functions in the PXA2xx and OMAP display devices. These devices
are little endian when they do DMA access.

(Since ARM softmmu is always compiled as little endian, this means
that the endian-dependent load and store functions are always little
endian, so this commit makes no functionally visible change.)

d20a580bc0 qapi: Change munging of CamelCase enum values
When munging enum values, the fact that we were passing the entire
prefix + value through camel_to_upper() meant that enum values
spelled with CamelCase could be turned into CAMEL_CASE.  However,
this provides a potential collision (both OneTwo and One-Two would
munge into ONE_TWO) for enum types, when the same two names are
valid side-by-side as QAPI member names.  By changing the generation
of enum constants to always be prefix + '_' + c_name(value,
False).upper(), and ensuring that there are no case collisions (in
the next patches), we no longer have to worry about names that
would be distinct as QAPI members but collide as variant tag names,
without having to think about what munging the heuristics in
camel_to_upper() will actually perform on an enum value.

Making the change will affect enums that did not follow coding
conventions, using 'CamelCase' rather than desired 'lower-case'.

Thankfully, there are only two culprits: InputButton and ErrorClass.
We already tweaked ErrorClass to make it an alias of QapiErrorClass,
where only the alias needs changing rather than the whole tree.  So
the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the
new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN).  That part
of this commit may later need reverting if we rename the enum
constants from 'WheelUp' to 'wheel-up' as part of moving
x-input-send-event to a stable interface; but at least we have
documentation bread crumbs in place to remind us (commit 513e7cd),
and it matches the fact that SDL constants are also spelled
SDL_BUTTON_WHEELUP.

7fb1cf1606 qapi: Don't let implicit enum MAX member collide
Now that we guarantee the user doesn't have any enum values
beginning with a single underscore, we can use that for our
own purposes.  Renaming ENUM_MAX to ENUM__MAX makes it obvious
that the sentinel is generated.

This patch was mostly generated by applying a temporary patch:

|diff --git a/scripts/qapi.py b/scripts/qapi.py
|index e6d014b..b862ec9 100644
|--- a/scripts/qapi.py
|+++ b/scripts/qapi.py
|@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = {
|     max_index = c_enum_const(name, 'MAX', prefix)
|     ret += mcgen('''
|     [%(max_index)s] = NULL,
|+// %(max_index)s
| };
| ''',
|                max_index=max_index)

then running:

$ cat qapi-{types,event}.c tests/test-qapi-types.c |
    sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list
$ git grep -l _MAX | xargs sed -i -f list

The only things not generated are the changes in scripts/qapi.py.

Rejecting enum members named 'MAX' is now useless, and will be dropped
in the next patch.

6c8d56a2e9 fw_cfg: replace ioport data read with generic method
IOPort read access is limited to one byte at a time by
fw_cfg_comb_valid(). As such, fw_cfg_comb_read() may safely
ignore its size argument (which will always be 1), and simply
call its fw_cfg_read() helper function once, returning 8 bits
via the least significant byte of a 64-bit return value.

This patch replaces fw_cfg_comb_read() with the generic method
fw_cfg_data_read(), and removes the unused fw_cfg_read() helper.

When called with size = 1, fw_cfg_data_read() acts exactly like
fw_cfg_read(), performing the same set of sanity checks, and
executing the while loop at most once (subject to the current
read offset being within range).

38bf20931a fw_cfg: add generic non-DMA read method
Introduce fw_cfg_data_read(), a generic read method which works
on all access widths (1 through 8 bytes, inclusive), and can be
used during both IOPort and MMIO read accesses.

To maintain legibility, only fw_cfg_data_mem_read() (the MMIO
data read method) is replaced by this patch. The new method
essentially unwinds the fw_cfg_data_mem_read() + fw_cfg_read()
combo, but without unnecessarily repeating all the validity
checks performed by the latter on each byte being read.

This patch also modifies the trace_fw_cfg_read prototype to
accept a 64-bit value argument, allowing it to work properly
with the new read method, but also remain backward compatible
with existing call sites.

66f8fd9dda fw_cfg: avoid calculating invalid current entry pointer
When calculating a pointer to the currently selected fw_cfg item, the
following is used:

  FWCfgEntry *e = &s->entries[arch][s->cur_entry & FW_CFG_ENTRY_MASK];

When s->cur_entry is FW_CFG_INVALID, we are calculating the address of
a non-existent element in s->entries[arch][...], which is undefined.

This patch ensures the resulting entry pointer is set to NULL whenever
s->cur_entry is FW_CFG_INVALID.

3f8752b4e5 fw_cfg: remove offset argument from callback prototype
Read callbacks are now only invoked at item selection, before any
data is read. As such, the value of the offset argument passed to
the callback will always be 0. Also, the two callback instances
currently in use both leave their offset argument unused.

This patch removes the offset argument from the fw_cfg read callback
prototype, and from the currently available instances. The unused
(write) callback prototype is also removed (write support was removed
earlier, in commit 023e3148).

3bef7e8aab fw_cfg: amend callback behavior spec to once per select
Currently, the fw_cfg internal API specifies that if an item was set up
with a read callback, the callback must be run each time a byte is read
from the item. This behavior is both wasteful (most items do not have a
read callback set), and impractical for bulk transfers (e.g., DMA read).

At the time of this writing, the only items configured with a callback
are "/etc/table-loader", "/etc/acpi/tables", and "/etc/acpi/rsdp". They
all share the same callback functions: virt_acpi_build_update() on ARM
(in hw/arm/virt-acpi-build.c), and acpi_build_update() on i386 (in
hw/i386/acpi.c). Both of these callbacks are one-shot (i.e. they return
without doing anything at all after the first time they are invoked with
a given build_state; since build_state is also shared across all three
items mentioned above, the callback only ever runs *once*, the first
time either of the listed items is read).

This patch amends the specification for fw_cfg_add_file_callback() to
state that any available read callback will only be invoked once each
time the item is selected. This change has no practical effect on the
current behavior of QEMU, and it enables us to significantly optimize
the behavior of fw_cfg reads during guest firmware setup, eliminating
a large amount of redundant callback checks and invocations.

6cecf09373 virtio-9p-device: add minimal unrealize handler
Since commit 4652f1640e "virtio-9p: add savevm
handlers", if the user hot-unplugs a quiescent 9p device and live
migrates, the source QEMU crashes before migration completetion...
This happens because virtio-9p devices have a realize handler which
calls virtio_init() and register_savevm().  Both calls store pointers
to the device internals, that get dereferenced during migration even
if the device got unplugged.

This patch simply adds an unrealize handler to perform minimal
cleanup and avoid the crash.  Hot unplug of non-quiescent 9p devices
is still not supported in QEMU, and not supported by linux guests
either.

f0ada3608a xen/MSI-X: latch MSI-X table writes
The remaining log message in pci_msix_write() is wrong, as there guest
behavior may only appear to be wrong: For one, the old logic didn't
take the mask-all bit into account. And then this shouldn't depend on
host device state (i.e. the host may have masked the entry without the
guest having done so). Plus these writes shouldn't be dropped even when
an entry gets unmasked. Instead, if they can't be made take effect
right away, they should take effect on the next unmasking or enabling
operation - the specification explicitly describes such caching
behavior.

want to attach a second time.  If we ever create another failure mode,
we're setting up ourselves to using the same backend from multiple

79f2170789 sdhci: Sanitize "sdhci-pci" properties for future qomification
We currently fuse controller and card into a single device model, but
we intend qomify things properly and separate the two.  The properties
that really belong to the card would then have to somehow pass-through
to the card's properties.  To avoid that complication, either mark
them experimental or drop them.

Properties "capareg", "maxcurr" and the usual PCI device properties
belong to the controller.  Property "drive" belongs to the card;
rename it to "x-drive".  Properties "logical_block_size",
"physical_block_size", "min_io_size", "opt_io_size",
"discard_granularity" belong to the card, but have no effect; drop
them.
