5a67bb96b0 linux-user: convert target_mmap debug to tracepoint
It is a pain to re-compile when you need to debug and tracepoints are
a fairly low impact way to instrument QEMU.

88893f7c94 travis.yml: Remove the redundant clang-with-MAIN_SOFTMMU_TARGETS entry
We test clang with the MAIN_SOFTMMU_TARGETS twice, once without
sanitizers and once with sanitizers enabled. That's somewhat redundant
since if compilation and tests succeeded with sanitizers enabled, it
should also work fine without sanitizers. Thus remove the clang entry
without sanitizers to speed up the CI testing a little bit.

fb47fc6924 Added tests for close and change of logfile.
One test ensures that the logfile handle is still valid even if
the logfile is changed during logging.
The other test validates that the logfile handle remains valid under
the logfile lock even if the logfile is closed.

7606488c0e Add use of RCU for qemu_logfile.
This now allows changing the logfile while logging is active,
and also solves the issue of a seg fault while changing the logfile.

Any read access to the qemu_logfile handle will use
the rcu_read_lock()/unlock() around the use of the handle.
To fetch the handle we will use atomic_rcu_read().
We also in many cases do a check for validity of the
logfile handle before using it to deal with the case where the
file is closed and set to NULL.

The cases where we write to the qemu_logfile will use atomic_rcu_set().
Writers will also use call_rcu() with a newly added qemu_logfile_free
function for freeing/closing when readers have finished.

fc59d2d870 qemu_log_lock/unlock now preserves the qemu_logfile handle.
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a
handle to unlock.  This allows for changing the handle during logging
and ensures the lock() and unlock() are for the same file.

Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock()
calls (and the log("\n")), since the translator can longjmp out of the
loop if it attempts to translate an instruction in an inaccessible page.

b8121fe7c0 Add a mutex to guarantee single writer to qemu_logfile handle.
Also added qemu_logfile_init() for initializing the logfile mutex.

Note that inside qemu_set_log() we needed to add a pair of
qemu_mutex_unlock() calls in order to avoid a double lock in
qemu_log_close().  This unavoidable temporary ugliness will be
cleaned up in a later patch in this series.

9c5941a96a travis.yml: Enable builds on arm64, ppc64le and s390x
Travis recently added the possibility to test on these architectures,
too, so let's enable them in our travis.yml file to extend our test
coverage.

Unfortunately, the libssh in this Ubuntu version (bionic) is in a pretty
unusable Frankenstein state and libspice-server-dev is not available here,
so we can not use the global list of packages to install, but have to
provide individual package lists instead.

Also, some of the iotests crash when using "dist: bionic" on arm64
and ppc64le, thus these two builders have to use "dist: xenial" until
the problem is understood / fixed.

30729ae93b iotests: Provide a function for checking the creation of huge files
Some tests create huge (but sparse) files, and to be able to run those

existing checks in the iotests 005 and 220 with this function.

3edaa995e6 travis.yml: Run tcg tests with tci
So far we only have compile coverage for tci. But since commit
2f160e0f97 ("tci: Add implementation
for INDEX_op_ld16u_i64") has been included now, we can also run the
"tcg" and "qtest" tests with tci, so let's enable them in Travis now.
Since we don't gain much additional test coverage by compiling all
targets, and TCI is broken e.g. with the Sparc targets, we also limit
the target list to a reasonable subset now (which should still get us
test coverage by tests/boot-serial-test for example).

1e48931c0c tests/vm: Allow to set qemu-img path
By default VM build test use qemu-img from system's PATH to
create the image disk. Due the lack of qemu-img on the system
or the desire to simply use a version built with QEMU, it would
be nice to allow one to set its path. So this patch makes that
possible by reading the path to qemu-img from QEMU_IMG if set,
otherwise it fallback to default behavior.

1ee5e144ea pseries: disable migration-test if /dev/kvm cannot be used
On ppc64, migration-test only works with kvm_hv, and we already
have a check to verify the module is loaded.

kvm_hv module can be loaded in memory and /sys/module/kvm_hv exists,
but on some systems (like build systems) /dev/kvm can be missing
(by administrators choice).

And as kvm_hv exists test-migration is started but QEMU falls back to
TCG because it cannot be used:

    Could not access KVM kernel module: No such file or directory
    failed to initialize KVM: No such file or directory
    Back to tcg accelerator

And as the test is done with TCG, it fails.

As for s390x, we must check for the existence and the access rights
of /dev/kvm.

1d4ffe8dc7 Remove the core bluetooth code
It's been deprecated since QEMU v3.1. We've explicitly asked in the
deprecation message that people should speak up on qemu-devel in case
they are still actively using the bluetooth part of QEMU, but nobody
ever replied that they are really still using it.

I've tried it on my own to use this bluetooth subsystem for one of my
guests, but I was also not able to get it running anymore: When I was
trying to pass-through a real bluetooth device, either the guest did
not see the device at all, or the guest crashed.

Even worse for the emulated device: When running

 qemu-system-x86_64 -bt device:keyboard

QEMU crashes once you hit a key.

So it seems like the bluetooth stack is not only neglected, it is
completely bitrotten, as far as I can tell. The only attention that
this code got during the past years were some CVEs that have been
spotted there. So this code is a burden for the developers, without
any real benefit anymore. Time to remove it.

Note: hw/bt/Kconfig only gets cleared but not removed here yet.
Otherwise there is a problem with the *-softmmu/config-devices.mak.d
dependency files - they still contain a reference to this file which
gets evaluated first on some build hosts, before the file gets
properly recreated. To avoid breaking these builders, we still need
the file around for some time. It will get removed in a couple of
weeks instead.

70c059e926 ppc/pnv: Introduce PnvChipClass::xscom_pcba() method
The XSCOM bus is implemented with a QOM interface, which is mostly
generic from a CPU type standpoint, except for the computation of
addresses on the Pervasive Connect Bus (PCB) network. This is handled
by the pnv_xscom_pcba() function with a switch statement based on
the chip_type class level attribute of the CPU chip.

This can be achieved using QOM. Also the address argument is masked with
PNV_XSCOM_SIZE - 1, which is for POWER8 only. Addresses may have different
sizes with other CPU types. Have each CPU chip type handle the appropriate
computation with a QOM xscom_pcba() method.

3a1b70b66b ppc/pnv: Fix OCC common area region mapping
The OCC common area is mapped at a unique address on the system and
each OCC is assigned a segment to expose its sensor data :

  -------------------------------------------------------------------------
  | Start (Offset from | End           | Size     |Description            |
  | BAR2 base address) |               |          |                       |
  -------------------------------------------------------------------------
  |    0x00580000      |  0x005A57FF   |150kB     |OCC 0 Sensor Data Block|
  |    0x005A5800      |  0x005CAFFF   |150kB     |OCC 1 Sensor Data Block|
  |        :           |       :       |  :       |            :          |
  |    0x00686800      |  0x006ABFFF   |150kB     |OCC 7 Sensor Data Block|
  |    0x006AC000      |  0x006FFFFF   |336kB     |Reserved               |
  -------------------------------------------------------------------------

Maximum size is 1.5MB.

We could define a "OCC common area" memory region at the machine level
and sub regions for each OCC. But it adds some extra complexity to the
models. Fix the current layout with a simpler model.

8f09231631 ppc/pnv: Introduce PBA registers
The PBA bridge unit (Power Bus Access) connects the OCC (On Chip
Controller) to the Power bus and System Memory. The PBA is used to
gather sensor data, for power management, for sleep states, for
initial boot, among other things.

The PBA logic provides a set of four registers PowerBus Access Base
Address Registers (PBABAR0..3) which map the OCC address space to the
PowerBus space. These registers are setup by the initial FW and define
the PowerBus Range of system memory that can be accessed by PBA.

The current modeling of the PBABAR registers is done under the common
XSCOM handlers. We introduce a specific XSCOM regions for these
registers and fix :

 - BAR sizes and BAR masks
 - The mapping of the OCC common area. It is common to all chips and
   should be mapped once.  We will address per-OCC area in the next
   change.
 - OCC common area is in BAR 3 on P8

90cce00c7b ppc/pnv: Make PnvXScomInterface an incomplete type
PnvXScomInterface is an interface instance. It should never be
dereferenced. Drop the dummy type definition for extra safety,
which is the common practice with QOM interfaces.

While here also convert the bogus OBJECT_CHECK() to INTERFACE_CHECK().
