xen: add implementations of xen-block connect and disconnect functions...
...and wire in the dataplane.
This patch adds the remaining code to make the xen-block XenDevice
functional. The parameters that a block frontend expects to find are
populated in the backend xenstore area, and the 'ring-ref' and
'event-channel' values specified in the frontend xenstore area are
mapped/bound and used to set up the dataplane.

4.7. Also the function xen_device_bind_event_channel assign the return

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

xen: add xenstore watcher infrastructure
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

'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.

xen: introduce 'xen-block', 'xen-disk' and 'xen-cdrom'
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.

qemu/queue.h: reimplement QTAILQ without pointer-to-pointers
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.

We do not support Automake, but we can use Automake's code to beautify

scsi: esp: Defer command completion until previous interrupts have been handled
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.

esp-pci: Fix status register write erase control
Per AM53C974 datasheet, definition of "SCSI Bus and Control (SBAC)"
register:
Bit 24 'STATUS' Write Erase Control
This bit controls the Write Erase feature on bits 3:1 and bit 6 of the DMA
Status Register ((B)+54h). When this bit is programmed to '1', the state
of bits 3:1 are preserved when read. Bits 3:1 are only cleared when a '1'
is written to the corresponding bit location. For example, to clear bit 1,
the value of '0000_0010b' should be written to the register. When the DMA
Status Preserve bit is '0', bits 3:1 are cleared when read.
The status register is currently defined to bit 12, not bit 24.
Also, its implementation is reversed: The status is auto-cleared if
the bit is set to 1, and must be cleared explicitly when the bit is
set to 0. This results in spurious interrupts reported by the Linux
kernel, and in some cases even results in stalled SCSI operations.
Set SBAC_STATUS to bit 24 and reverse the logic to fix the problem.

accel: Improve selection of the default accelerator
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

tests/display-vga: Enable virtio-vga test
There are some "#ifdef CONFIG_VIRTIO_VGA" in the code here which
do not work as expected: CONFIG_VIRTIO_VGA is a Makefile switch,
but not a CPP macro, so the "guarded" code currently simply never
gets enabled.
So enable this code now unconditionally, with some runtime switches
for the architectures that have the VIRTIO_VGA device enabled by
default. Looking at the other if-statement in the main function here,
it also seems like this test was originally supposed to be running
on "mips" and "alpha", too, so enable it now for these architectures
in the Makefile, too.

configure: bump spice-server required version to 0.12.5
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.

memory-device: rewrite address assignment using ranges
Let's rewrite it properly using ranges. This fixes certain overflows that
are right now possible. E.g.
qemu-system-x86_64 -m 4G,slots=20,maxmem=40G -M pc \
-object memory-backend-file,id=mem1,share,mem-path=/dev/zero,size=2G
-device pc-dimm,memdev=mem1,id=dimm1,addr=-0x40000000
Now properly errors out instead of succeeding. (Note that qapi
parsing of huge uint64_t values is broken and fixes are on the way)

CSR predicate functions are added to the CSR table.
mstatus.FS and counter enable checks are moved
to predicate functions and two new predicates are
added to check misa.S for s* CSRs and a new PMP
CPU feature for pmp* CSRs.
Processors that don't implement S-mode will trap
on access to s* CSRs and processors that don't
implement PMP will trap on accesses to pmp* CSRs.
PMP checks are disabled in riscv_cpu_handle_mmu_fault

* Final parts of XIVE support for pseries (without KVM)
* Preliminary work for PHB hotplug
* Starting to use TCG vector operations
This includes some changes in the PCI core, which Michael Tsirkin
requested come through this tree, since they're primarily of interest
for ppc.
