e890966d60 ppc patch queue 2018-01-11
This pull request supersedes ppc-for-2.12-20180108 and several before
 it.  The earlier pull request included a patch which exposed a bug in
 the ARM TCG backend.  I've pulled that out and will repost once the
 ARM bug is fixed (a patch has been posted by Richard Henderson).
 
 Higlights from this series:
   * SLOF update
   * Several new devices for embedded platforms
   * Fix to correctly set compatiblity mode for hotplugged CPUs
   * dtc compile fix for older MacOS versions

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

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.

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().

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.

This finally allows us to instantiate the APB directly using standard qdev

d736f119da block: Allow graph changes in subtree drained section
We need to remember how many of the drain sections in which a node is
were recursive (i.e. subtree drain rather than node drain), so that they
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.

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.

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.

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'.

eaba8f34f0 net: move CRC32 calculation from compute_mcast_idx() into its own net_crc32() function
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.

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.

kvm-i8259 can also use it in the future.

f68d98b21f scsi: provide general-purpose functions to manage sense data
Extract the common parts of scsi_sense_buf_to_errno, scsi_convert_sense
and scsi_target_send_command's REQUEST SENSE handling into two new
functions scsi_parse_sense_buf and scsi_build_sense_buf.

Fix a bug in scsi_target_send_command along the way; the length was
written in buf[10] rather than buf[7].

80ceb07a83 cpu: refactor cpu_address_space_init()
Normally we create an address space for that CPU and pass that address
space into the function.  Let's just do it inside to unify address space
creations.  It'll simplify my next patch to rename those address spaces.

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.
