417adc2d50 hw/ide/pci.c: Coding style update to fix checkpatch errors
Spaces are required around a + operator and if statements should have
braces even for single line. Also make it simpler by reversing the
condition instead of breaking the loop.

1a519323d3 via-ide: always use legacy IRQ 14/15 routing
The existing code uses fixed PCI IRQ routing on IRQ 14 rather than legacy IRQ
14/15 routing as documented in the datasheet.

With the changes in this patchset guest OSs now correctly detect and configure
the VIA controller in legacy IRQ routing mode, allowing the incorrect fixed
PCI IRQ routing to be removed.

Note that this fixed legacy IRQ 14/15 routing is identical to similar behaviour
in the early PIIX IDE controllers.

fa8ac1b769 via-ide: initialise IDE controller in legacy mode

f703a04ce5 add device_legacy_reset function to prepare for reset api change
Provide a temporary device_legacy_reset function doing what
device_reset does to prepare for the transition with Resettable
API.

All occurrence of device_reset in the code tree are also replaced
by device_legacy_reset.

The new resettable API has different prototype and semantics
(resetting child buses as well as the specified device). Subsequent
commits will make the changeover for each call site individually; once
that is complete device_legacy_reset() will be removed.

ed78352a59 ide: Fix incorrect handling of some PRDTs in ide_dma_cb()
The commit a718978ed5 from July 2015 introduced the assertion which
implies that the size of successful DMA transfers handled in ide_dma_cb()
should be multiple of 512 (the size of a sector). But guest systems can
initiate DMA transfers that don't fit this requirement.

For fixing that let's check the number of bytes prepared for the transfer
by the prepare_buf() handler. The code in ide_dma_cb() must behave
according to the Programming Interface for Bus Master IDE Controller
(Revision 1.0 5/16/94):
1. If PRDs specified a smaller size than the IDE transfer
   size, then the Interrupt and Active bits in the Controller
   status register are not set (Error Condition).
2. If the size of the physical memory regions was equal to
   the IDE device transfer size, the Interrupt bit in the
   Controller status register is set to 1, Active bit is set to 0.
3. If PRDs specified a larger size than the IDE transfer size,
   the Interrupt and Active bits in the Controller status register
   are both set to 1.

This ought to help cases reported by Nutanix where iSCSI returns a

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

qemu/processor.h, qemu/qsp.h, qemu/queue.h, qemu/thread-posix.h,
qemu/thread.h, qemu/timer.h, and a few more.

Include qemu/main-loop.h only where it's needed.  Touching it now
recompiles only some 1700 objects.  For block/aio.h and
qemu/event_notifier.h, these numbers drop from 5600 to 2800.  For the
others, they shrink only slightly.

650d103d3e Include hw/hw.h exactly where needed
In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

The previous commits have left only the declaration of hw_error() in
hw/hw.h.  This permits dropping most of its inclusions.  Touching it
now recompiles less than 200 objects.

According to hw/ide/internal's file comment, only files in hw/ide/ are
supposed to include it.  Drag reality slightly closer to supposition.

Three includes outside hw/ide remain: hw/arm/sbsa-ref.c,
include/hw/ide/pci.h, and include/hw/misc/macio/macio.h.  Turns out
board code needs ide-internal.h to wire up IDE stuff.  More cleanup is

2ae16a6aa4 Include generated QAPI headers less
Some of the generated qapi-types-MODULE.h are included all over the
place.  Changing a QAPI type can trigger massive recompiling.  Top
scorers recompile more than 1000 out of some 6600 objects (not
counting tests and objects that don't depend on qemu/osdep.h):

    6300 qapi/qapi-builtin-types.h
    5700 qapi/qapi-types-run-state.h
    3900 qapi/qapi-types-common.h
    3300 qapi/qapi-types-sockets.h
    3000 qapi/qapi-types-misc.h
    3000 qapi/qapi-types-crypto.h
    3000 qapi/qapi-types-job.h
    3000 qapi/qapi-types-block-core.h
    2800 qapi/qapi-types-block.h
    1300 qapi/qapi-types-net.h

Clean up headers to include generated QAPI headers only where needed.
Impact is negligible except for hw/qdev-properties.h.

This header includes qapi/qapi-types-block.h and
qapi/qapi-types-misc.h.  They are used only in expansions of property
definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and
DEFINE_PROP_OFF_AUTO().  Moving their inclusion from
hw/qdev-properties.h to the users of these macros avoids pointless
recompiles.  This is how other property definition macros, such as
DEFINE_PROP_NETDEV(), already work.

Improves things for some of the top scorers:

    3600 qapi/qapi-types-common.h
    2800 qapi/qapi-types-sockets.h
     900 qapi/qapi-types-misc.h
    2200 qapi/qapi-types-crypto.h
    2100 qapi/qapi-types-job.h

The given context is only stored and kept up to date when changing
AioContexts. Actually applying the stored AioContext to the root node

9a585f3ea6 hw/ide/ahci: Add a Kconfig switch for the AHCI-ICH9 device
Some of our machines (like the ARM cubieboard) use CONFIG_AHCI for an AHCI
sysbus device, but do not use CONFIG_PCI since they do not feature a PCI
bus. With CONFIG_AHCI but without CONFIG_PCI, currently linking fails:

    ../hw/ide/ich.o: In function `pci_ich9_ahci_realize':
    hw/ide/ich.c:124: undefined reference to `pci_allocate_irq'
    hw/ide/ich.c:126: undefined reference to `pci_register_bar'

    hw/ide/ich.c:158: undefined reference to `msi_uninit'
    ../hw/ide/ich.o:(.data.rel+0x50): undefined reference to `vmstate_pci_device'

We must only compile ich.c if CONFIG_PCI is available, too, so introduce a
new config switch for this device.

7c28b925b7 build: convert pci.mak to Kconfig
Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available.  However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.

Done mostly with the following script:

  while read i; do
     i=${i%=y}; i=${i#CONFIG_}
     sed -i -e'/^config '$i'$/!b' -en \
            -e'a\' -e'    default y if PCI_DEVICES\' -e'    depends on PCI' \
          `grep -lw $i hw/*/Kconfig`
  done < default-configs/pci.mak

followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

82f5181777 kconfig: introduce kconfig files
The Kconfig files were generated mostly with this script:

  for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do
    set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
    shift
    if test $# = 1; then
      cat >> $(dirname $1)/Kconfig << EOF
config ${i#CONFIG_}
    bool

EOF
      git add $(dirname $1)/Kconfig
    else
      echo $i $*
    fi
  done
  sed -i '$d' hw/*/Kconfig
  for i in hw/*; do
    if test -d $i && ! test -f $i/Kconfig; then
      touch $i/Kconfig
      git add $i/Kconfig
    fi
  done

Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.
