4b10c8d701 ebus: wire up OBIO interrupts to APB pbm via qdev GPIOs
This enables us to remove the static array mapping in the ISA IRQ
handler (and the embedded reference to the APB device) by formalising
the interrupt wiring via the qdev GPIO API.

For more clarity we replace the APB OBIO interrupt numbers with constants
designating the interrupt source, and rename isa_irq_handler() to
ebus_isa_irq_handler().

cacd05805e apb: remove pci_apb_init() and instantiate APB device using qdev
By making the special_base and mem_base values qdev properties, we can move
the remaining parts of pci_apb_init() into the pbm init() and realize()
functions.

This finally allows us to instantiate the APB directly using standard qdev
create/init functions in sun4u.c.

c796eddaad sun4u: remove pci_ebus_init() function
This is initialisation that should really take place in the ebus realize
function. As part of this we also rework the ebus IRQ mapping so that
instead of having to pass in the array of pbm_irqs, we obtain a reference
to them by looking up the APB device during ebus realize.

bcf9e2c2f2 sun4u: fix assert when adding NICs which aren't the in-built model
Commit 8d93297 introduced a bug whereby non-inbuilt NICs are realized before

same except omitting the realize as originally intended.

6864fa3897 sun4u: update PCI topology to include simba PCI bridges
This patch updates the sun4u model to being much closer to a real Ultra 5
by moving devices behind the 2 simba PCI bridges (A and B) as found on real
hardware.

The most noticeable change introduced by this patchset is that in-built devices
are no longer attached to the PCI root bus, but instead behind PCI bridge A.
Along with this the interrupt routing is updated accordingly to match the
official documentation.

Since the existing code currently bypasses the PCI bridge interrupt
swizzling, the interrupt mapping functions are reorganised so that
pci_pbm_map_irq() is used by the PCI bridges and pci_apb_map_irq() is
used by the PCI host bridge.

Behind the sabre PCI host bridge, the PCI IO space now needs to be
split into two separate halves at 0x8000000. Therefore we also setup a new
PCI IO space region of increased size on the PCI host bridge and enable
32-bit PCI IO accesses to allow IO accesses to reach devices behind PCI
bridge B correctly.

As part of this change we also combine the onboard sunhme NIC and the ebus
into a single multi-function device as done on a real Ultra 5. For other
NICs the existing behaviour is preserved, i.e. we initialise them and
place them into the next free slot on PCI bus B.

Finally we mark the physically unavailable slots (plus slot 0 in busA) as
reserved to ensure that users can't plug devices into non-existent slots
which will break interrupt routing.

Note: since this commit changes PCI topology and interrupt routing, an
updated openbios-sparc64 binary is included with this commit containing the
associated changes to maintain bisectability.

fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

4482e05cbb cpu: make cpu_generic_init() abort QEMU on error

and aborts process.
Some users assume that call can't fail and don't check
for failure, though they should have checked for it.

In either cases cpu_generic_init() failure is fatal,
so instead of checking for failure and reporting
it various ways, make cpu_generic_init() report
errors in consistent way and terminate QEMU on failure.

2059839baa hw: Default -drive to if=ide explicitly where it works
Block backends defined with -drive if=ide are meant to be picked up by
machine initialization code: a suitable frontend gets created and
wired up automatically.

if=ide drives not picked up that way can still be used with -device as
if they had if=none, but that's unclean and best avoided.  Unused ones
produce an "Orphaned drive without device" warning.

-drive parameter "if" is optional, and the default depends on the
machine type.  If a machine type doesn't specify a default, the
default is "ide".

Many machine types default to if=ide, even though they don't actually
have an IDE controller.  A future patch will change these defaults to
something more sensible.  To prepare for it, this patch makes default
"ide" explicit for the machines that actually pick up if=ide drives:

* alpha: clipper
* arm/aarch64: spitz borzoi terrier tosa
* i386/x86_64: generic-pc-machine (with concrete subtypes pc-q35-*
  pc-i440fx-* pc-* isapc xenfv)
* mips64el: fulong2e
* mips/mipsel/mips64el: malta mips
* ppc/ppc64: mac99 g3beige prep
* sh4/sh4eb: r2d
* sparc64: sun4u sun4v

Note that ppc64 machine powernv already sets an "ide" default
explicitly.  Its IDE controller isn't implemented, yet.

so far.

Later we can generalize it when another affected target gets support

qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

7ef295ea5b loader: Add data swap option to load-elf
Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.

The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.

As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

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.

f8ed85ac99 Fix bad error handling after memory_region_init_ram()
Symptom:

    $ qemu-system-x86_64 -m 10000000
    Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
    upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
    Aborted (core dumped)

Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions.  Before the commit, we report the error and exit(1), in
one place, ram_block_add().  The commit lifts the error handling up
the call chain some, to three places.  Fine.  Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".

The three places are:

* memory_region_init_ram()

  Commit 4994653 (right after commit ef701d7) lifted the error
  handling further, through memory_region_init_ram(), multiplying the
  incorrect use of &error_abort.  Later on, imitation of existing
  (bad) code may have created more.

* memory_region_init_ram_ptr()

  The &error_abort is still there.

* memory_region_init_rom_device()

  Doesn't need fixing, because commit 33e0eb5 (soon after commit
  ef701d7) lifted the error handling further, and in the process
  changed it from &error_abort to passing it up the call chain.
  Correct, because the callers are realize() methods.

Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:

    @r@
    expression mr, owner, name, size, err;
    position p;
    @@
            memory_region_init_ram(mr, owner, name, size,
    (
    -                              &error_abort
    +                              &error_fatal
    |
                                   err@p
    )
                                  );
    @script:python@
        p << r.p;
    @@
    print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)

When the last argument is &error_abort, it gets replaced by
&error_fatal.  This is the fix.

If the last argument is anything else, its position is reported.  This
lets us check the fix is complete.  Four positions get reported:

* ram_backend_memory_alloc()

  Error is passed up the call chain, ultimately through
  user_creatable_complete().  As far as I can tell, it's callers all
  handle the error sanely.

* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()

  DeviceClass.realize() methods, errors handled sanely further up the
  call chain.

We're good.  Test case again behaves:

    $ qemu-system-x86_64 -m 10000000
    qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
    [Exit 1 ]

The next commits will repair the rest of commit ef701d7's damage.

19d2b5e6ff i8257: rewrite DMA_schedule to avoid hooking into the CPU loop
The i8257 DMA controller uses an idle bottom half, which by default
does not cause the main loop to exit.  Therefore, the DMA_schedule
function is there to ensure that the CPU relinquishes the iothread
mutex to the iothread.

However, this is not enough since the iothread will call
aio_compute_timeout() and go to sleep again.  In the iothread
world, forcing execution of the idle bottom half is much simpler,
and only requires a call to qemu_notify_event().  Do it, removing
the need for the "cpu_request_exit" pseudo-irq.  The next patch
will remove it.

arm/virt doesn't.  It could be argued that that's an error in
"hw/arm/virt.c"; on the other hand, all of the other fw_cfg providing
boards set the interface version to 1 manually, despite the device
coming from the same, shared implementation. Therefore, instead of
adding

    fw_cfg_add_i32(fw_cfg, FW_CFG_ID, 1);

to arm/virt, consolidate all such existing calls in the fw_cfg
initialization code.

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.

d8f94e1bb2 ide: Update ide_drive_get to be HBA agnostic
Instead of duplicating the logic for the if_ide
(bus,unit) mappings, rely on the blockdev layer
for managing those mappings for us, and use the
drive_get_by_index call instead.

This allows ide_drive_get to work for AHCI HBAs
as well, and can be used in the Q35 initialization.

Lastly, change the nature of the argument to
ide_drive_get so that represents the number of
total drives we can support, and not the total
number of buses. This will prevent array overflows
if the units-per-default-bus property ever needs
to be adjusted for compatibility reasons.

a1cf8be550 sun4u: switch second PCI-ebus bridge BAR over to PCI IO space
The ebus is the sun4u equivalent of the old ISA bus which is already mapped at
the beginning of PCI IO space within QEMU. NetBSD attempts to find the physical
addresses of devices connected to the ebus by parsing the BARs of the PCI-ebus
bridge and using the base address found by matching both the address space
type and range for a particular ebus address.

Since the second PCI-ebus bridge BAR is already aliased onto IO space, switch
the BAR over to match and reduce the size to 0x1000 which is enough to cover
all the legacy ioport devices whilst leaving the remaining IO space for other
PCI devices. This allows NetBSD SPARC64 to correctly detect and access devices
on the ebus.

c165473269 hw: Clean up bogus default boot order
We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.

Machines that care:

* pc and its variants

  Accept up to three letters 'a', 'b' (undocumented alias for 'a'),
  'c', 'd' and 'n'.  Reject all others (fatal with -boot).

* nseries (n800, n810)

  Check whether order starts with 'n'.  Silently ignored otherwise.

* prep, g3beige, mac99

  Extract the first character the machine understands (subset of
  'a'..'f').  Silently ignored otherwise.

* spapr

  Accept an arbitrary string (vl.c restricts it to contain only
  'a'..'p', no duplicates).

* sun4[mdc]

  Use the first character.  Silently ignored otherwise.

Strip characters these machines ignore from their default boot order.

For all other machines, remove the unused default boot order
alltogether.

Note that my rename of QEMUMachine member boot_order to
default_boot_order and QEMUMachineInitArgs member boot_device to
boot_order has a welcome side effect: it makes every use of boot
orders visible in this patch, for easy review.

multiple PCI roots, that may no longer be the case.  This patch adds a root
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters.  NICs created new-style, with
-device can of course be put anywhere.
