For TYPE_DEVICE, the dc->reset() function is not called on system resets
yet. Until that is changed, we have to manually register a reset handler.
Let's provide qdev_reset_all_fn(), that can directly be used - just like
the reset handler that is already available for qbus.

This patch adds deterministic replay for hardware periodic countdown timers.
ptimer uses bottom halves layer to execute such an asynchronous callback.
We put this callback into the replay queue instead of bottom halves one.
When checkpoint is met by main loop thread, the replay queue is processed
and callback is executed. Binding callback moment to one of the checkpoints
makes it deterministic.

Expansion of [*] suffix is very slow because index expansion is done using
trial and error strategy, starting every time from zero and retrying with
the next index until insertion succeeds. With large number of already added
properties this process takes huge amount of time (O(n^2) complexity).
Some architectures (like ARM) use very large amount of IRQ pins in interrupt
controller models. This flaw makes machine startup extremely slow
(~20 seconds for ARM64 with 32 CPUs). This patch decreases this time down to
~10 seconds.

Commit ef701d7 screwed up handling of out-of-memory conditions.
Before the commit, we report the error and exit(1), in one place. 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 previous commit fixed up uses of memory_region_init_ram(). One of
them was replaced by memory_region_init_resizeable_ram() [sic!] in
commit a166614, so Coccinelle missed it. Fix it up.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
On ARM, commit ac9d32e396 postponed the
memory preparation for boot until the machine init done notifier. This
has for consequence to insert ROM at machine init done time.
However the rom_load_all function stayed called before the ROM are
inserted. As a consequence the rom_load_all function does not do
everything it is expected to do, on ARM.
It currently registers the ROM reset notifier but does not iterate through
the registered ROM list. the isrom field is not set properly. This latter
is used to report info in the monitor and also to decide whether the
rom->data can be freed on ROM reset notifier.
To fix that regression the patch moves the rom_load_all call after
machine init done. We also take the opportunity to rename the rom_load_all
function into rom_check_and_resgister_reset() and integrate the
rom_load_done in it.

If the user forgot if=none on their drive specification they're likely
to get an error message because the drive is assigned once automatically
by QEMU and once by the manual id=/drive= user command line specification.
Improve the error message produced in this case to explicitly guide the
user towards if=none.
We rephrase the "drive conflict but not for an if=something" error as
well to keep the wording in line.
The two cases that change are:
(1) Drive specified as to be auto-connected and also manually connected
(and the board does handle this if= type):
qemu-system-x86_64 -nodefaults -display none \
-drive if=scsi,file=tmp.qcow2,id=foo -device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use because it has been automatically connected to another device (did
you need 'if=none' in the drive options?)
(2) Drive specified to be manually connected in two different ways:
qemu-system-x86_64 -nodefaults -display none \
-drive if=none,file=tmp.qcow2,id=foo -device ide-hd,drive=foo \
-device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use by another device

The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

qdev_init() is a wrapper around setting property "realized" to true,
plus error handling that passes errors to qerror_report_err().
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
All code has been modernized to avoid qdev_init() and its
inappropriate error handling. We can finally drop it.

index of the monitor, but uses cpu index 0 as default (except for x86).
This function can then later be used from a non-monitor context.

When the argument is non-zero, qemu_opts_foreach() stops on callback
returning non-zero, and returns that value.
When the argument is zero, it doesn't stop, and returns the bit-wise
inclusive or of all the return values. Funky :)
The callers that pass zero could just as well pass one, because their
callbacks can't return anything but zero:
* qemu_add_globals()'s callback qdev_add_one_global()
* qemu_config_write()'s callback config_write_opts()
* main()'s callbacks default_driver_check(), drive_enable_snapshot(),
vnc_init_func()
Drop the parameter, and always stop.

For QEMUMachine types override the value during the registration of

geometry: hd_geometry_guess function autodetects the drive geometry.
This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.
blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise
it will set default 512 value.
The blkconf_blocksizes call was added to all users of BlkConf.

Three kinds of callers:
1. On failure, report the error and abort
Passing &error_abort does the job. No functional change.
2. On failure, report the error and exit()
This is qdev_prop_set_drive_nofail(). Error reporting moves from
qdev_prop_set_drive() to its caller. Because hiding away the error
in the monitor right before exit() isn't helpful, replace
qerror_report_err() by error_report_err(). Shouldn't make a
difference, because qdev_prop_set_drive_nofail() should never be
used in QMP context.
3. On failure, report the error and recover
This is usb_msd_init() and scsi_bus_legacy_add_drive(). Error
reporting and freeing the error object moves from
qdev_prop_set_drive() to its callers.
Because usb_msd_init() can't run in QMP context, replace
qerror_report_err() by error_report_err() there.
No functional change.
scsi_bus_legacy_add_drive() calling qerror_report_err() is of
course inappropriate, but this commit merely makes it more obvious.
The next one will clean it up.

Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic
creation of sysbus devices. However, at present it is used only for the
PPC E500 target, with plans for the ARM "virt" target in the immediate
future.
To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

-global lets you set a nice booby-trap for yourself:

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.

This patch solves this issue by not using set/get_pinter() and set and

- 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:

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.

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.
Signed-off-by: Alexander Graf <agraf@suse.de>
Sysbus devices have a range of MMIO regions they expose. The exact number
of regions is device specific and internal information to the device model.
Expose whether a region exists via a public interface. That way our platform
bus enumeration code can dynamically determine how many regions exist.
Signed-off-by: Alexander Graf <agraf@suse.de>
Sysbus devices can get their IRQ lines connected to other devices. It is
possible to figure out which IRQ line a connection is on and whether a sysbus
device even provides an IRQ connector at a specific offset.
This patch exposes helpers to make this information publicly accessible. We
will need it for the platform bus dynamic sysbus enumeration.
Signed-off-by: Alexander Graf <agraf@suse.de>
Now that we can properly map sysbus devices that haven't been connected to
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.
Signed-off-by: Alexander Graf <agraf@suse.de>
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.

Re-implement the Sysbus GPIOs to use the existing TYPE_DEVICE
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.

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.

Change the qtest intercept handler to accept just the individual IRQ
being intercepted as opaque. n is still expected to be correctly set
as for the original intercepted irq. qemu_intercept_irq_in is updated
accordingly.
Then covert the qemu_irq_intercept_out call to use qdev intercept
version. This stops qtest from having to mess with the raw IRQ pointers
(still has to mess with names and counts but a step in the right
direction).

Re-implement as a link setter. This should allow the QOM framework to

We need to add a default parent for the connecting input incase it's

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.

Only allow a GPIO name to be one or the other. Inputs and outputs are
functionally different and should be in different namespaces. Prepares
support for the QOMification of IRQs as Links or Child objects.
The alternative is to munge names .e.g. with "-in" or "-out" suffixes
when giving QOM names. But that reduces clarity and if there are cases
out there where users want I and O with same name they can manually add
their own suffixes.

Currently GlobalProperty.not_used=false has multiple meanings:
* It may be a property for a hotpluggable device, which may or may not
have been used by a device;
* It may be a machine-type-provided property, which may or may not have
been used by a device.
* It may be a user-provided property that was actually not used by
any device.
Simplify the logic by having two separate fields: 'user_provided' and
'used'. This allows the entire global property validation logic to be
contained in a single function, and allows more specific error messages.

A subsequent patch to ppc/spapr needs to load the RTAS blob into
qemu memory rather than target memory (so it can later be copied
into the right spot at machine reset time).
I would use load_image() but it is marked deprecated because it
doesn't take a buffer size as argument, so let's add load_image_size()
that does.

At present, this function doesn't have partial cleanup implemented,
which will cause resource leaks in some scenarios.
Example:
1. Assume that "dc->realize(dev, &local_err)" executes successful
and local_err == NULL;
2. device hotplug in hotplug_handler_plug() executes but fails
(it is prone to occur). Then local_err != NULL;
3. error_propagate(errp, local_err) and return. But the resources
which have been allocated in dc->realize() will be leaked.
Simple backtrace:
dc->realize()
|->device_realize
|->pci_qdev_init()
|->do_pci_register_device()
|->etc.
Add fuller cleanup logic which assures that function can
goto appropriate error label as local_err population is
detected at each relevant point.

Forcefully unrealize all children regardless of errors in earlier

rather than report an error immediately. Therefore store the first
child unrealization failure and propagate it at the end. We also
forcefully unregister vmsd and unrealize actual object, too.

This introduces an NMI (Non Maskable Interrupt) interface with
a single nmi_monitor_handler() method. A machine or a device can
implement it. This searches for an QOM object with this interface
and if it is implemented, calls it. The callback implements an action
required to cause debug crash dump on in-kernel debugger invocation.
The callback returns Error**.
This adds a nmi_monitor_handle() helper which walks through
all objects to find the interface. The interface method is called
for all found instances.
This adds support for it in qmp_inject_nmi(). Since no architecture
supports it at the moment, there is no change in behaviour.
This changes inject-nmi command description for HMP and QMP.

When a device is unparented (i.e. made completely hidden from management)
we want to send a DEVICE_DELETED event only if the device actually was
realized. This avoids raising DEVICE_DELETED events when device_add
fails.
However, this does not work right for recursively-deleted
devices: the whole tree is _first_ unrealized, _then_ unparented.
Then device_unparent sees realized==false and fails to trigger
the event. The solution is simply to move have_realized into
the DeviceState struct. If device_add fails, we never set the
new field to true and DEVICE_DELETED is not sent.
Fixes qemu-iotests testcase 067 (broken by commit 5942a19, though that
commit in turn fixed a possible segfault in the same test).

Allocate each IRQ individually on array allocations. This prepares for
QOMification of IRQs, where pointers to individual IRQs may be taken
and handed around for usage as QOM Links. The g_renew() scheme used here
is too fragile and would break all existing links should an IRQ list
be extended.
We now have to pass the IRQ count to qemu_free_irqs(). We have so few
call sites however, so this change is reasonably trivial.

When the patch was posted that became 5c21ce7 (qdev: Realize buses
on device realization, 2014-03-12), it included recursive realization
and unrealization of devices when the bus's "realized" property
was toggled.
However, due to the same old worries about recursive realization
and prerequisites not being realized yet, those hunks were dropped when
committing the patch. Unfortunately, this causes a use-after-free bug
(easily reproduced by a PCI hot-unplug action).
Before the patch, device_unparent behaved as follows:
for each child bus
unparent bus ----------------------------.
| for each child device |
| unparent device ---------------. |
| | unrealize device | |
| | call dc->unparent | |
| '------------------------------- |
'----------------------------------------'
unrealize device
After the patch, it behaves as follows instead:
unrealize device --------------------.
| for each child bus |
| unrealize bus (A) |
'------------------------------------'
for each child bus
unparent bus ----------------------.
| for each child device |
| unrealize device (B) |
| call dc->unparent |
'----------------------------------'
At the step marked (B) the device might use data from the bus that is
not available anymore due to step (A).
To fix this, we need to unrealize devices before step (A). To sidestep
concerns about recursive realization, only do recursive unrealization
and leave the "value && !bus->realized" case as it is.
The resulting flow is:
for each child bus
unrealize bus ---------------------.
| for each child device |
| unrealize device (B) |
| call bc->unrealize (A) |
'----------------------------------'
unrealize device
for each child bus
unparent bus ----------------------.
| for each child device |
| unparent device |
'----------------------------------'
where everything is "powered down" before it is unassembled.

This can help a user understand why -global was ignored.
For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.
This is currently clear when the wrong property is provided:
out/x86_64-softmmu/qemu-system-x86_64 -global cirrus-vga.vram_size_mb=16 -monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)
qemu-system-x86_64: Property '.vram_size_mb' not found
Aborted (core dumped)
vs
out/x86_64-softmmu/qemu-system-x86_64 -global vga.vram_size_mb=16 -monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)
