We better stop right away. For now, errors would be partially ignored
(so the guest might get informed or the device might get unplugged),
although actual plug/unplug will be reported as failed to the user.
While at it, properly move the check to the pre_plug handler for the plug
case, as we can test the slot state before the device will be realized.

This patch adds create and destroy function for XenBlockDevice-s so that
they can be created automatically when the Xen toolstack instantiates a new
PV backend via xenstore. When the XenBlockDevice is created this way it is
also necessary to create a 'drive' which matches the configuration that the
Xen toolstack has written into xenstore. This is done by formulating the
parameters necessary for each 'blockdev' layer of the drive and then using
qmp_blockdev_add() to create the layers. Also, for compatibility with the
legacy 'xen_disk' implementation, an iothread is automatically created for
the new XenBlockDevice. This, like the driver layers, will be destroyed
after the XenBlockDevice is unrealized.
The legacy backend scan for 'qdisk' is removed by this patch, which makes
the 'xen_disk' code is redundant. The code will be removed by a subsequent
patch.

...that maintains compatibility with existing Xen toolstacks.
Xen toolstacks instantiate PV backends by simply writing information into
xenstore and expecting a backend implementation to be watching for this.
This patch adds a new 'xen-backend' module to allow individual XenDevice
implementations to register create and destroy functions. The creator
will be called when a tool-stack instantiates a new backend in this way,
and the destructor will then be called after the resulting XenDevice
object is unrealized.
To support this it is also necessary to add new watchers into the XenBus
implementation to handle enumeration of new backends and also destruction
of XenDevice-s when the toolstack sets the backend 'online' key to 0.
NOTE: This patch only adds the framework. A subsequent patch will add a
creator function for xen-block devices.

This patch adds the remaining code to make the xen-block XenDevice

Patch squashed with:
Patch "xen: add event channel interface for XenDevice-s" makes use of
the type xenevtchn_port_or_error_t, but this isn't avaiable before Xen
4.7. Also the function xen_device_bind_event_channel assign the return
value of xenevtchn_bind_interdomain to channel->local_port but check the
result for error with xendev->local_port.
Fix by:
- removing local_port from struct XenDevice as it isn't use anywere.
- adding a compatibility typedef for xenevtchn_port_or_error_t for Xen
4.6 and earlier.
As extra, replace the type of XenEventChannel->local_port by
evtchn_port_t.

A Xen PV frontend communicates its state to the PV backend by writing to
the 'state' key in the frontend area in xenstore. It is therefore
necessary for a XenDevice implementation to be notified whenever the
value of this key changes.
This patch adds code to do this as follows:
- an 'fd handler' is registered on the libxenstore handle which will be
triggered whenever a 'watch' event occurs
- primitives are added to xen-bus-helper to add or remove watch events
- a list of Notifier objects is added to XenBus to provide a mechanism
to call the appropriate 'watch handler' when its associated event
occurs
The xen-block implementation is extended with a 'frontend_changed' method,
which calls as-yet stub 'connect' and 'disconnect' functions when the
relevant frontend state transitions occur. A subsequent patch will supply
a full implementation for these functions.

This patch adds a new source module, xen-bus-helper.c, which builds on
basic libxenstore primitives to provide functions to create (setting
permissions appropriately) and destroy xenstore areas, and functions to
'printf' and 'scanf' nodes therein. The main xen-bus code then uses
these primitives [1] to initialize and destroy the frontend and backend
areas for a XenDevice during realize and unrealize respectively.
The 'xen-block' implementation is extended with a 'get_name' method that
returns the VBD number. This number is required to 'name' the xenstore
areas.
NOTE: An exit handler is also added to make sure the xenstore areas are
cleaned up if QEMU terminates without devices being unrealized.
[1] The 'scanf' functions are actually not yet needed, but they will be
needed by code delivered in subsequent patches.

This patch adds new XenDevice-s: 'xen-disk' and 'xen-cdrom', both derived
from a common 'xen-block' parent type. These will eventually replace the
'xen_disk' (note the underscore rather than hyphen) legacy PV backend but
it is illustrative to build up the implementation incrementally, along with
the XenBus/XenDevice framework. Subsequent patches will therefore add to
these devices' implementation as new features are added to the framework.
After this patch has been applied it is possible to instantiate new
'xen-disk' or 'xen-cdrom' devices with a single 'vdev' parameter, which
accepts values adhering to the Xen VBD naming scheme [1]. For example, a
command-line instantiation of a xen-disk can be done with an argument
similar to the following:
-device xen-disk,vdev=hda
The implementation of the vdev parameter formulates the appropriate VBD
number for use in the PV protocol.

...and xen_backend.h to xen-legacy-backend.h
Rather than attempting to convert the existing backend infrastructure to
be QOM compliant (which would be hard to do in an incremental fashion),
subsequent patches will introduce a completely new framework for Xen PV
backends. Hence it is necessary to re-name parts of existing code to avoid
name clashes. The re-named 'legacy' infrastructure will be removed once all
backends have been ported to the new framework.
This patch is purely cosmetic. No functional change.

The new definition of QTAILQ does not require passing the headname,
remove it.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
|

QTAILQ is a doubly linked list, with a pointer-to-pointer to the last
element from the head, and the previous element from each node.
But if you squint enough, QTAILQ becomes a combination of a singly-linked
forwards list, and another singly-linked list which goes backwards and
is circular. This is the idea that lets QTAILQ implement reverse
iteration: only, because the backwards list points inside the node,
accessing the previous element needs to go two steps back and one
forwards.
What this patch does is implement it in these terms, without actually
changing the in-memory layout at all. The coexistence of the two lists
is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards
pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in
both directions; the union is needed so that the forwards pointer can
have the correct type, as a sort of poor man's template. While there
are other ways to get the same layout without a union, this one has
the advantage of simpler operation in the debugger, because the fields
tqh_first and tqe_next still exist as before the patch. Those fields are
also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them.
The advantage of the new representation is that the two-back-one-forward
dance done by backwards accesses can be done all while operating on
QTailQLinks. No casting to the head struct is needed anymore because,
even though the QTailQLink's forward pointer is a void *, we can use
typeof to recover the correct type. This patch only changes the
implementation, not the interface. The next patch will remove the head
struct name from the backwards visit macros.

This will be needed when we change the QTAILQ head and elem structs
to unions. However, it is also consistent with the usage elsewhere
in QEMU for other list head structs (see for example FsMountList).
Note that most QTAILQs only need their name in order to do backwards
walks. Those do not break with the struct->union change, and anyway
the change will also remove the need to name heads when doing backwards
walks, so those are not touched here.

Most list head structs need not be given a name. In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed. In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct. So clean up everything, not giving a
name except in the rare case where it is necessary.

The guest OS reads RSTAT, RSEQ, and RINTR, and expects those registers
to reflect a consistent state. However, it is possible that the registers
can change after RSTAT was read, but before RINTR is read, when
esp_command_complete() is called.
Guest OS qemu
-------- ----
[handle interrupt]
Read RSTAT
esp_command_complete()
RSTAT = STAT_ST
esp_dma_done()
RSTAT |= STAT_TC
RSEQ = 0
RINTR = INTR_BS
Read RSEQ
Read RINTR RINTR = 0
RSTAT &= ~STAT_TC
RSEQ = SEQ_CD
The guest OS would then try to handle INTR_BS combined with an old
value of RSTAT. This sometimes resulted in lost events, spurious
interrupts, guest OS confusion, and stalled SCSI operations.
A typical guest error log (observed with various versions of Linux)
looks as follows.
scsi host1: Spurious irq, sreg=13.

scsi host1: Aborting command [84531f10:2a]

When compiling with "--disable-tcg", we currently still use "tcg"
as default accelerator. "kvm" should be used in this case instead.
Also, some downstream distros provide QEMU binaries which have "kvm"
in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use
KVM by default - and some users might want to do something similar
with upstream binaries, too. Accomodate them by using "kvm:tcg" as
default when we detect such a binary name.

The qemu_create_display_surface_guestmem() function was added in
commit a77549b3ffcc24c32ee4e but apparently never used. Remove it.
(The API of this function is in any case awkward as a generic
function: it assumes that a physical address uniquely identifies
a piece of memory in the system, which is mostly but not
always true.)

Looking at chardev/spice.c code, I realize compilation was broken for
a while with spice-server < 0.12.3. Let's bump required version
to 0.12.5, released May 19 2014, instead of adding more #ifdef.
(this patch combines changes from an early version and some of
Frediano "[PATCH 2/2] spice: Bump required spice-server version to
0.12.6")
According to repology, all the distros that are build target platforms
for QEMU include it:
RHEL-7: 0.14.0
Debian (Stretch): 0.12.8
Debian (Jessie): 0.12.5
FreeBSD (ports): 0.14.0
OpenSUSE Leap 15: 0.14.0
Ubuntu (Xenial): 0.12.6
Note that a previous version of this patch was bumping version to
0.12.6. Unfortunately, Debian Jessie (oldstable) is stuck with spice
server 0.12.5, and QEMU should keep building until after 2y of current
stable (Stretch), which will be around June 17th 2019. Qemu 4.1
should thus be free of bumping to spice-server 0.12.6 during 4.1
development cycle.

The 'dual' sPAPR IRQ backend supports both interrupt mode, XIVE
exploitation mode and the legacy compatibility mode (XICS). both modes
are not supported at the same time.
The machine starts with the legacy mode and a new interrupt mode can
then be negotiated by the CAS process. In this case, the new mode is
activated after a reset to take into account the required changes in
the machine. These impact the device tree layout, the interrupt
presenter object and the exposed MMIO regions in the case of XIVE.

Today, the interrupt presenter is linked to a CPU using the
cpu_intc_create() method of the sPAPR IRQ backend. The resulting
object is assigned to the PowerPCCPU 'intc' pointer whatever the
interrupt mode, XICS or XIVE.
To support the 'dual' interrupt mode, we will need to distinguish
between the two presenter objects and for that, we plan to introduce a
second interrupt presenter object pointer under the PowerPCCPU. The
modifications below move the assignment of the presenter object under
the cpu_intc_create() method to prepare ground for the future changes.
Both sPAPR and PowerNV machines are impacted.

This adds cleanup counterparts to pci_register_root_bus(),
pci_root_bus_new(), and pci_bus_irqs().
These cleanup routines are needed in the case of hotpluggable
PCIHostBridge implementations. Currently we can rely on the
object_unparent()'ing of the PCIHostState recursively unparenting
and cleaning up it's child buses, but we need explicit calls
to also:
1) remove the PCIHostState from pci_host_bridges global list.
otherwise, we risk accessing freed memory when we access
the list later
2) clean up memory allocated in pci_bus_irqs()
Both are handled outside the context of any particular bus or
host bridge's init/realize functions, making it difficult to
avoid the need for explicit cleanup functions without remodeling
how PCIHostBridges are created. So keep it simple and just add
them for now.
