By default, we have ioeventfd enabled, so the IO request processing is
in IO thread; in the vcpu thread, guest mode is returned to as quickly

When the AHCI HBA device is migrated, all of the information that
led to the request being created is stored in the AHCIDevice
structures, except for pointers into guest data where return
information needs to be stored.
The "cur_cmd" field is usually responsible for this.
To rebuild the cur_cmd pointer post-migration, we can utilize
the busy_slot index to figure out where the command header
we are still processing is.
This allows a machine in a halted state from rerror=stop or
werror=stop to be migrated and resume operations without issue.

This is easy, since start_dma already restarts processing from the
beginning of the PRDT.
Migration is also easy to cover; the comment about busy_slot is
wrong, busy_slot will only be set if there is an error. In this
case we have nothing to do really. The core IDE code will restart
the operation and command list processing will proceed after the
erroring command has been completed.

Amazingly, we weren't doing this before.
Make sure we migrate the IDEState structure that belongs to
the AHCIDevice.IDEBus structure during migrations.
No version numbering changes because AHCI is not officially
migratable (and we can all see with good reason why) so we
do not impact any official builds by altering the stream and
leaving it at version 1.
This fixes the rerror=stop/werror=stop test case where we wish
to migrate a halted job. Previously, the error code would not
migrate, so even if the job completed successfully, AHCI would
report an error because it would still have the placeholder
error code from initialization time.

This only breaks backwards migration compatibility if the bus is in
an error state. It is in principle possible to avoid this by making
two subsections (one for version 1, and one for version 2, but with
the same name) with different "_needed" callbacks. The v1 callback would
return true if error_status != 0 and the bus is PATA; the v2 callback
would return true if error_status != 0 and the bus is AHCI.
Forward migration keeps working.

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.

When setting "realized" fails, scsi_bus_legacy_add_drive() passes the

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

Commit a818a4b changed scsi_bus_legacy_handle_cmdline() to report
errors from scsi_bus_legacy_add_drive() with error_report() in
addition to returning them. That's inappropriate.
Two kinds of callers:
1. realize methods (devices "esp", "virtio-scsi-device" and
"spapr-vscsi")
The error object gets passed up the call chain until it gets
reported again and freed.
Example:
$ qemu-system-arm -M virt -S -display none \
> -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \
> -device nec-usb-xhci -device usb-storage,drive=foo \
> -device virtio-scsi-pci
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Device initialization failed
qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized
The second message in this error cascade comes from
scsi_bus_legacy_handle_cmdline(). The error object then gets
passed up to the qdev_init() called from
virtio_scsi_pci_init_pci(), which reports it again.
2. init methods (devices "am53c974", "dc390", "lsi53c895a",
"lsi53c810", "megasas", "megasas-gen2")
init methods need to report their errors with qerror_report().
These don't. The inappropriate error_report() papers over the bug.
error_report() isn't the same as qerror_report() in QMP context,
but this can't actually happen: QMP can still only hot-plug, and
callers call scsi_bus_legacy_handle_cmdline() only on cold-plug.
Except for sysbus_esp_realize(), but that can't be hot-plugged at
all, as far as I can tell.
Fix the init methods and drop the inappropriate error_report() in
scsi_bus_legacy_handle_cmdline().

The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.
This patch moves it into the RTC device's own state structure, were it
belongs. This requires a small change to the migration stream format. In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.
Since we're changing the migration format, this also takes the opportunity
to:
* Change the rtc offset from a value in seconds to a value in
nanoseconds, allowing nanosecond offsets between host and guest
rtc time, if desired.
* Remove both the already unused "next_irq" field and now unused
"rtc_offset" field from the new version of the spapr migration
stream

At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code. This
becomes inconvenient as we extend it in various ways.
This patch makes the PAPR RTC a separate device in the qemu device model.
For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure. That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).

In the 'pseries' machine the real time clock is provided by a
paravirtualized firmware interface rather than a device per se; the RTAS
get-time-of-day and set-time-of-day calls.
Out current implementations of those work directly off host time (with
an offset), not respecting options such as clock=vm which can be
specified in the -rtc command line option.
This patch reworks the RTAS RTC code to respect those options, primarily
by basing them on the qemu_clock_get_ns(rtc_clock) function instead of
directly on qemu_get_timedate() (which essentially handles host time, not
virtual rtc time).
As a bonus, this means our get-time-of-day function now also returns
nanoseconds.

At the moment sPAPR only supports 512MB window for MMIO BARs. However
modern devices might want bigger 64bit BARs.
This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.
The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.
The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.
SLOF change is required to utilize this extension.

pseries guests can have large numbers of PCI host bridges. To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.
There are some problems with the details at present:
* The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
* No limit is imposed on the "index" property and large values can
translate to extremely large window addresses. With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.
This patch addresses this, by making "index" unsigned, and imposing a
limit. Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being. It's fairly easy to extend if
we discover we need more.

let's add an alias to RAM and IOMMU memory region, and enable/disable

This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.
This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.

When do memory balloon, it takes the 'ram_size' as the VM's current ram size,
But 'ram_size' is the startup configured ram size, it does not take into
account the hotplugged memory.
As a result, the balloon result will be confused.
Steps to reproduce:
(1)Start VM: qemu -m size=1024,slots=4,maxmem=8G
(2)In VM: #free -m : 1024M
(3)qmp balloon 512M
(4)In VM: #free -m : 512M
(5)hotplug pc-dimm 1G
(6)In VM: #free -m : 1512M
(7)qmp balloon 256M
(8)In VM: #free -m :1256M
We expect the VM's available ram size to be 256M after 'qmp balloon 256M'
command, but VM's real available ram size is 1256M.
For "qmp balloon" is not performance critical code, we use function
'get_current_ram_size' to get VM's current ram size.

The global parameter 'ram_size' does not take into account
the hotplugged memory.
In some codes, we use 'ram_size' as current VM's real RAM size,
which is not correct.
Add function 'get_current_ram_size' to calculate VM's current RAM size,
it will enumerate present memory devices and also plus ram_size.

ASSERT (TrsRing != NULL) [4]
UsbEnumerateNewDev() in the USB bus driver issues a GET_DESCRIPTOR
request, in order to determine the number of configurations that the
endpoint supports. The requests consists of three stages (three TRBs),
setup, data, and status. The length of the response is determined in [1],
namely from the transfer event that the host controller generates in
response to the request's middle stage (ie. the data stage).
If the length of the answer is correct (a full GET_DESCRIPTOR request
takes 18 bytes), then the XHCI driver that underlies the USB bus driver
"snoops" (caches) the descriptor data for later [2].
Later, the USB bus driver sends a SET_CONFIG request. The underlying XHCI
driver allocates a transfer ring for the endpoint, relying on the data
snooped and cached in step [2].
Finally, the USB keyboard driver submits an asynchronous interrupt
transfer to manage the keyboard. As part of this it asserts [4] that the
ring has been allocated in step [3].
And this ASSERT() fires. The root cause can be found in the way QEMU
handles the initial GET_DESCRIPTOR request.
Again, that request consists of three stages (TRBs, Transfer Request
Blocks), "setup", "data", and "status". The XhcCreateTransferTrb()
function sets the IOC ("Interrupt on Completion") flag in each of these
TRBs.
According to the XHCI specification, the host controller shall generate a
Transfer Event in response to *each* individual TRB of the request that
had the IOC flag set. This means that QEMU should queue three events:
setup, data, and status, for edk2's XHCI driver.
However, QEMU only generates two events:
- one for the setup (ie. 1st) stage,
- another for the status (ie. 3rd) stage.
No event is generated for the middle (ie. data) stage. The loop in QEMU's
xhci_xfer_report() function runs three times, but due to the "reported"
variable, only the first and the last TRBs elicit events, the middle (data
stage) results in no event queued.
As a consequence:
- When handling the GET_DESCRIPTOR request, XhcCheckUrbResult() in [1]
does not update the response length from zero.
- XhcControlTransfer() thinks that the response is invalid (it has zero
length payload instead of 18 bytes), hence [2] is not reached; the
device descriptor is not stashed for later, and the number of possible
configurations is left at zero.
- When handling the SET_CONFIG request, (NumConfigurations == 0) from
above prevents the allocation of the endpoint's transfer ring.
- When the keyboard driver tries to use the endpoint, the ASSERT() blows
up.
The solution is to correct the emulation in QEMU, and to generate a
transfer event whenever IOC is set in a TRB.
The patch replaces
!reported && (IOC || foo) == !reported && IOC ||
!reported && foo
with
IOC || (!reported && foo) == IOC ||
!reported && foo
which only changes how
reported && IOC
is handled. (Namely, it now generates an event.)

vga_common_init() doesn't allow more than 256 MiB vram size and silently
shrinks any larger value. qxl_dirty_surfaces() used the unshrinked size
via qxl->shadow_rom.surface0_area_size when accessing the memory, which
resulted in segfault.
Add a workaround for this case and an assert if it happens again.
We have to bump the vga memory limit too, because 256 MiB wouldn't have
allowed 8k (it requires more than 128 MiB).
1024 MiB doesn't work, but 512 MiB seems fine.

Linux v4.0-rc1 vfio-pci introduced a new virtual interrupt to allow
the kernel to request a device from the user. When signaled, QEMU
will by default attmempt to hot-unplug the device. This is a one-
shot attempt with the expectation that the kernel will continue to
poll for the device if it is not returned. Returning the device when
requested is the expected standard model of cooperative usage, but we
also add an option option to disable this feature. Initially this
opt-out is set as an experimental option because we really should
honor kernel requests for the device.

where it is used in hw/scsi/virtio-scsi-dataplane.c is when it is

(and is actually wrong because this leads to s->blocker potentially
being NULL when blk_op_block_all() is called in virtio-scsi.c), so move

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

This mimics what is done in qdev_device_add, and lets the device be
freed in case something goes wrong. Otherwise, object_unparent returns
immediately without freeing the device, which is on the other hand left
in the parent bus's list of children.
scsi_bus_legacy_handle_cmdline then returns an error, and the HBA is
destroyed as well with object_unparent. But the lingering device that
was not removed in scsi_bus_legacy_add_drive cannot be removed now either,
and bus_unparent gets stuck in an infinite loop trying to empty the list
of children.
The right fix of course would be to assert in bus_add_child that the
device already has a bus, and remove the "safety net" that adds the
drive to the QOM tree in device_set_realized. I am not yet sure whether
that would entail changing all callers to qdev_create (as well as
isa_create and usb_create and the corresponding _try_create versions).

$ 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.

Implement DeviceClass methods realize() and unrealize() instead of
init() and exit(). The core's initialization errors now get
propagated properly, and QMP sends them instead of an unspecific
"Device initialization failed" error. Unrealize can't fail, so no
change there.
PCIDeviceClass is unchanged: it still provides init() and exit().
Therefore, device models' errors are still not propagated.
