Cédric Le Goater b168a138a8 ppc/pnv: change powernv_ prefix to pnv_ for overall naming consistency
The 'pnv' prefix is now used for all and the routines populating the
device tree start with 'pnv_dt'. The handler of the PnvXScomInterface
is also renamed to 'dt_xscom' which should reflect that it is
populating the device tree under the 'xscom@' node of the chip.

Mark Cave-Ayland 0ea833c249 sun4u: split IOMMU device out from apb.c to sun4u_iommu.c
By separating the sun4u IOMMU device into new sun4u_iommu.c and sun4m_iommu.h
files we noticeably simplify apb.c whilst bringing sun4u in line with all the
other IOMMU-supporting architectures.

Mark Cave-Ayland aea5b07101 apb: QOMify IOMMU
This is in preparation to split the IOMMU device out of the APB. As part of
this commit we also enforce separation of the IOMMU and APB devices by using
a QOM object link to pass the IOMMU reference and accessing the IOMMU registers
via a separate memory region mapped into the APB config space rather than
directly.

Mark Cave-Ayland 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().

Mark Cave-Ayland 33c5eb02c4 apb: remove busA property from PBMPCIBridge state
Since the previous commit the only remaining use of the qdev busA property is
to configure the PCI bridge in front of the onboard ebus devices differently
to allow early OpenBIOS serial console access.

Instead we can now manually update the PCI configuration for bridge A in
pci_pbm_reset() and thus completely remove the busA property from the
PBMPCIBridge state.

Mark Cave-Ayland 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.

This is initialisation that should really take place in the ebus realize

instead of having to pass in the array of pbm_irqs, we obtain a reference

can be correctly applied when children are added or removed during the
drained section.

With this change, it is safe to modify the graph even inside a
bdrv_subtree_drained_begin/end() section.

Kevin Wolf b016558590 block: Add bdrv_subtree_drained_begin/end()
bdrv_drained_begin() waits for the completion of requests in the whole
subtree, but it only actually keeps its immediate bs parameter quiesced
until bdrv_drained_end().

Add a version that keeps the whole subtree drained. As of this commit,
graph changes cannot be allowed during a subtree drained section, but
this will be fixed soon.

Kevin Wolf 0152bf400f block: Don't notify parents in drain call chain
This is in preparation for subtree drains, i.e. drained sections that
affect not only a single node, but recursively all child nodes, too.

Calling the parent callbacks for drain is pointless when we just came
from that parent node recursively and leads to multiple increases of
bs->quiesce_counter in a single drain call. Don't do it.

In order for this to work correctly, the parent callback must be called
for every bdrv_drain_begin/end() call, not only for the outermost one:

If we have a node N with two parents A and B, recursive draining of A
should cause the quiesce_counter of B to increase because its child N is
drained independently of B. If now B is recursively drained, too, A must
increase its quiesce_counter because N is drained independently of A
only now, even if N is going from quiesce_counter 1 to 2.

Sergio Andres Gomez Del Real c97d6d2cdf i386: hvf: add code base from Google's QEMU repository
This file begins tracking the files that will be the code base for HVF
support in QEMU. This code base is part of Google's QEMU version of
their Android emulator, and can be found at
https://android.googlesource.com/platform/external/qemu/+/emu-master-dev

This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted
Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is
appropriately licensed under GPL v2-or-later, except for the code inside
x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel),
is licensed GPL v2-only.

This code base already implements a very great deal of functionality,
although Google's version removed from Vertuu's the support for APIC
page and hyperv-related stuff. According to the Android Emulator Release
Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now
enabled by default on macOS for 32-bit x86 images to improve performance
and macOS compatibility", although we better use with caution for, as the
same Revision warns us, "If you experience issues with it specifically,
please file a bug report...". The code hasn't seen much update in the
last 5 months, so I think that we can further develop the code with
occasional visiting Google's repository to see if there has been any
update.

On top of Google's code, the following changes were made:

- add code to the configure script to support the --enable-hvf argument.
If the OS is Darwin, it checks for presence of HVF in the system. The
patch also adds strings related to HVF in the file qemu-options.hx.
QEMU will only support the modern syntax style '-M accel=hvf' no enable
hvf; the legacy '-enable-hvf' will not be supported.

- fix styling issues

- add glue code to cpus.c

- move HVFX86EmulatorState field to CPUX86State, changing the
the emulation functions to have a parameter with signature 'CPUX86State *'
instead of 'CPUState *' so we don't have to get the 'env'.

Separate out the standard ethernet CRC32 calculation into a new net_crc32()
function, renaming the constant POLYNOMIAL to POLYNOMIAL_BE to make it clear
that this is a big-endian CRC32 calculation.

As part of the constant rename, remove the duplicate definition of POLYNOMIAL
from eepro100.c and use the new POLYNOMIAL_BE constant instead.

Once this is complete remove the existing CRC32 implementation from
compute_mcast_idx() and call the new net_crc32() function in its place.

Marc-André Lureau d09c4a4787 chardev: fix backend events regression with mux chardev
Kirill noticied that on recent versions on QEMU he was not able to
trigger SysRq to invoke debug capabilites of Linux Kernel.  He tracked
it down to qemu_chr_be_event() ignoring CHR_EVENT_BREAK due s->be
being NULL. The bug was introduced in 2.8, commit a4afa548fc ("char:
move front end handlers in CharBackend"). Since the commit, the
qemu_chr_be_event() failed to deliver CHR_EVENT_BREAK due to
qemu_chr_fe_init() does not set s->be in case of mux.

Let's fix this by teaching mux to send an event to the frontend with
the focus.

Daniel P. Berrange 62473511ec sockets: remove obsolete code that updated listen address
When listening on unix/tcp sockets there was optional code that would update
the original SocketAddress struct with the info about the actual address that
was listened on. Since the conversion of everything to QIOChannelSocket, no
remaining caller made use of this feature. It has been replaced with the ability
to query the listen address after the fact using the function
qio_channel_socket_get_local_address. This is a better model when the input
address can result in listening on multiple distinct sockets.

Their last user went away in commit f51074cdc6, "pci-hotplug-old: Has
been dead for five major releases, bury", v2.3.0.  Remove them, as new
code should use QemuOpts or maybe keyval_parse() instead.

The relevant code from iothread_run() is:

  while (!atomic_read(&iothread->stopping)) {
      aio_poll(iothread->ctx, true);

and iothread_stop():

  iothread->stopping = true;
  aio_notify(iothread->ctx);
  ...
  qemu_thread_join(&iothread->thread);

The following scenario can occur:

1. IOThread:
  while (!atomic_read(&iothread->stopping)) -> stopping=false

2. Main loop:
  iothread->stopping = true;
  aio_notify(iothread->ctx);

3. IOThread:
  aio_poll(iothread->ctx, true); -> hang

The bug is explained by the AioContext->notify_me doc comments:

  "If this field is 0, everything (file descriptors, bottom halves,
  timers) will be re-evaluated before the next blocking poll(), thus the
  event_notifier_set call can be skipped."

The problem is that "everything" does not include checking
iothread->stopping.  This means iothread_run() will block in aio_poll()
if aio_notify() was called just before aio_poll().

This patch fixes the hang by replacing aio_notify() with
aio_bh_schedule_oneshot().  This makes aio_poll() or g_main_loop_run()
to return.

Implementing this properly required a new bool running flag.  The new
flag prevents races that are tricky if we try to use iothread->stopping.
Now iothread->stopping is purely for iothread_stop() and
iothread->running is purely for the iothread_run() thread.

Mao Zhongyi 9d3b155186 hw/block: Fix the return type
When the function no success value to transmit, it usually make the
function return void. It has turned out not to be a success, because
it means that the extra local_err variable and error_propagate() will
be needed. It leads to cumbersome code, therefore, transmit success/
failure in the return value is worth.

So fix the return type of blkconf_apply_backend_options(),
blkconf_geometry() and virtio_blk_data_plane_create() to avoid it.

Stefan Hajnoczi 78f1d3d6a6 coroutine: simplify co_aio_sleep_ns() prototype
The AioContext pointer argument to co_aio_sleep_ns() is only used for
the sleep timer.  It does not affect where the caller coroutine is
resumed.

Due to changes to coroutine and AIO APIs it is now possible to drop the
AioContext pointer argument.  This is safe to do since no caller has
specific requirements for which AioContext the timer must run in.

This patch drops the AioContext pointer argument and renames the
function to simplify the API.

  io: introduce a network socket listener API

Peter Maydell 57d1f6d7ce sparc: Make sure we mmap at SHMLBA alignment
SPARC Linux has an oddity that it insists that mmap()
of MAP_FIXED memory must be at an alignment defined by
SHMLBA, which is more aligned than the page size
(typically, SHMLBA alignment is to 16K, and pages are 8K).
This is a relic of ancient hardware that had cache
aliasing constraints, but even on modern hardware the
kernel still insists on the alignment.

To ensure that we get mmap() alignment sufficient to
make the kernel happy, change QEMU_VMALLOC_ALIGN,
qemu_fd_getpagesize() and qemu_mempath_getpagesize()
to use the maximum of getpagesize() and SHMLBA.

In particular, this allows 'make check' to pass on Sparc:
we were previously failing the ivshmem tests.

Daniel P. Berrange 530473924d io: introduce a network socket listener API
The existing QIOChannelSocket class provides the ability to
listen on a single socket at a time. This patch introduces
a QIONetListener class that provides a higher level API
concept around listening for network services, allowing
for listening on multiple sockets.

Greg Kurz bb2d8ab636 spapr: fix LSI interrupt specifiers in the device tree
LoPAPR 1.1 B.6.9.1.2 describes the "#interrupt-cells" property of the
PowerPC External Interrupt Source Controller node as follows:

“#interrupt-cells”

  Standard property name to define the number of cells in an interrupt-
  specifier within an interrupt domain.

  prop-encoded-array: An integer, encoded as with encode-int, that denotes
  the number of cells required to represent an interrupt specifier in its
  child nodes.

  The value of this property for the PowerPC External Interrupt option shall
  be 2. Thus all interrupt specifiers (as used in the standard “interrupts”
  property) shall consist of two cells, each containing an integer encoded
  as with encode-int. The first integer represents the interrupt number the
  second integer is the trigger code: 0 for edge triggered, 1 for level
  triggered.

This patch fixes the interrupt specifiers in the "interrupt-map" property
of the PHB node, that were setting the second cell to 8 (confusion with
IRQ_TYPE_LEVEL_LOW ?) instead of 1.

VIO devices and RTAS event sources use the same format for interrupt
specifiers: while here, we introduce a common helper to handle the
encoding details.

Igor Mammedov f47bd1c839 spapr: replace numa_get_node() with lookup in pc-dimm list
SPAPR is the last user of numa_get_node() and a bunch of
supporting code to maintain numa_info[x].addr list.

Get LMB node id from pc-dimm list, which allows to
remove ~80LOC maintaining dynamic address range
lookup list.

It also removes pc-dimm dependency on numa_[un]set_mem_node_id()
and makes pc-dimms a sole source of information about which
node it belongs to and removes duplicate data from global
numa_info.

Cédric Le Goater 7718375584 spapr: introduce a spapr_qirq() helper
xics_get_qirq() is only used by the sPAPR machine. Let's move it there
and change its name to reflect its scope. It will be useful for XIVE
support which will use its own set of qirqs.
