Remove the "default y" for USB_XHCI_SYSBUS because
sysbus devices are not user creatable; boards that use them will
specify them manually with "imply" or "select" clauses.

It would be nice to keep the ability to remove PCIe and USB from microvm,
since thos can be disabled on the command line and therefore should not
be included if QEMU is configured --without-default-devices.  However
it's too late for 5.2 to figure out a place for the DSDT creation code.

  trace: use STAP_SDT_V2 to work around symbol visibility

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

QEMU binaries no longer launch successfully with recent SystemTap
releases. This is because modular QEMU builds link the sdt semaphores
into the main binary instead of into the shared objects where they are
used. The symbol visibility of semaphores is 'hidden' and the dynamic
linker prints an error during module loading:

  $ ./configure --enable-trace-backends=dtrace --enable-modules ...
  ...
  Failed to open module: /builddir/build/BUILD/qemu-4.2.0/s390x-softmmu/../block-curl.so: undefined symbol: qemu_curl_close_semaphore

The long-term solution is to generate per-module dtrace .o files and
link them into the module instead of the main binary.

In the short term we can define STAP_SDT_V2 so dtrace(1) produces a .o
file with 'default' symbol visibility instead of 'hidden'. This
workaround is small and easier to merge for QEMU 5.2 and downstream
backports.

The zPCI group and function structures are big endian. However, we do
not consistently store them as big endian locally, and are missing some
conversions.

Let's just store the structures as host endian instead and convert to
big endian when actually handling the instructions retrieving the data.

Also fix the layout of ClpReqQueryPciGrp: g is actually only 8 bit. This
also fixes accesses on little endian hosts, and makes accesses on big
endian hosts consistent.

Hot-unplugging a vfio-pci device on s390x causes a QEMU crash:

qemu-system-s390x: ../softmmu/memory.c:2772:
 do_address_space_destroy: Assertion `QTAILQ_EMPTY(&as->listeners)' failed.

In s390, the IOMMU address space is freed during device unplug but the
associated vfio-pci device may not yet be finalized and therefore may
still have a listener registered to the IOMMU address space.

Commit a2166410 ("spapr_pci: Unregister listeners before destroying
the IOMMU address space") previously resolved this issue for spapr_pci.
We are now seeing this in s390x; it would seem the possibility for this
issue was already present but based on a bisect commit 2d24a646
("device-core: use RCU for list of children of a bus") has now changed
the timing such that it is now readily reproducible.

Add logic to ensure listeners are removed before destroying the address
space.

The Control Program Name Code (CPNC) portion of the diag318
info must be set within the SIE block of each VCPU in the
configuration. The handler will iterate through each VCPU
and dirty the diag318_info reg to be synced with KVM on a
subsequent sync_regs call.

Additionally, the diag318 info resets must be handled via
userspace. As such, QEMU will reset this value for each
VCPU during a modified clear, load normal, and load clear
reset event.

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

qauthz_list_file_complete() is wrong that way: it passes @errp to
qauthz_list_file_complete() without checking for failure.  If it runs
into another failure, it trips error_setv()'s assertion.  Reproducer:

    $ qemu-system-x86_64 -nodefaults -S -display none -object authz-list-file,id=authz0,filename=
    qemu-system-x86_64: ../util/error.c:59: error_setv: Assertion `*errp == NULL' failed.

This series was largely built on the assumption that IPI numbers are
numerically equal to vCPU ids. Even if this happens to be the case
in practice with the default machine settings, this ceases to be true
if VSMT is set to a different value than the number of vCPUs per core.
This causes bogus IPI numbers to be created in KVM from a guest stand
point. This leads to unknow results in the guest, including crashes
or missing vCPUs (see BugLink) and even non-fatal oopses in current
KVM that lacks a check before accessing misconfigured HW (see [1]).

A tentative patch was sent (see [2]) but it seems too complex to be
merged in an RC. Since the original changes are essentially an
optimization, it seems safer to revert them for now. The damage is
done by commit acbdb995 ("spapr/xive: Allocate IPIs independently
from the other sources") but the previous patches in the series are
really preparatory patches. So this reverts the whole series:

eab0a2d0 ("spapr/xive: Allocate vCPU IPIs from the vCPU contexts")
acbdb995 ("spapr/xive: Allocate IPIs independently from the other sources")
fa94447a ("spapr/xive: Use kvmppc_xive_source_reset() in post_load")

free 'QObject' memory at the end of the function.

The TMP105 datasheet says that in Interrupt Mode (when TM==1) the device
signals an alert when the temperature equals or exceeds the T_high value and
then remains high until a device register is read or the device responds to
the SMBUS Alert Response address, or the device is put into Shutdown Mode.
Thereafter the Alert pin will only be re-signalled when temperature falls
below T_low; alert can then be cleared in the same set of ways, and the
device returns to its initial "alert when temperature goes above T_high"
mode. (If this textual description is confusing, see figure 3 in the
TI datasheet at https://www.ti.com/lit/gpn/tmp105

 .)

We were misimplementing this as a simple "always alert if temperature is
above T_high or below T_low" condition, which gives a spurious alert on
startup if using the "T_high = 80 degrees C, T_low = 75 degrees C" reset
limit values.

Implement the correct (hysteresis) behaviour by tracking whether we
are currently looking for the temperature to rise over T_high or
for it to fall below T_low. Our implementation of the comparator
mode (TM==0) wasn't wrong, but rephrase it to match the way that
interrupt mode is now handled for clarity.

The TMP105 datasheet (https://www.ti.com/lit/gpn/tmp105

) says that the
power-up reset values for the T_low and T_high registers are 80 degrees C
and 75 degrees C, which are 0x500 and 0x4B0 hex according to table 5.  These
values are then shifted right by four bits to give the register reset
values, since both registers store the 12 bits of temperature data in bits
[15..4] of a 16 bit register.

We were resetting these registers to zero, which is problematic for Linux
guests which enable the alert interrupt and then immediately take an
unexpected overtemperature alert because the current temperature is above
freezing...

In commit 76346b62 we tried to add a configure check that
the libgio pkg-config data was correct, which builds an executable
linked against it.  Unfortunately this doesn't catch the problem
(missing static library dependency info), because a "do nothing" test
source file doesn't have any symbol references that cause the linker
to pull in .o files from libgio.a, and so we don't see the "missing
symbols from libmount" error that a full QEMU link triggers.

(The ineffective test went unnoticed because of a typo that
effectively disabled libgio unconditionally, but after commit
3569a5df fixed that, a static link of the system emulator on
Ubuntu stopped working again.)

Improve the gio test by having the test source fragment reference a
g_dbus function (which is what is indirectly causing us to end up
wanting functions from libmount).

In the mtspr helper we attempt to check for "is the timer disabled"
with "if (env->ttmr & TIMER_NONE)".  This is wrong because TIMER_NONE
is zero and the condition is always false (Coverity complains about
the dead code.)

The correct check would be to test whether the TTMR_M field in the
register is equal to TIMER_NONE instead.  However, the
cpu_openrisc_timer_update() function checks whether the timer is
enabled (it looks at cpu->env.is_counting, which is set to 0 via
cpu_openrisc_count_stop() when the TTMR_M field is set to
TIMER_NONE), so there's no need to check for "timer disabled" in the
target/openrisc code.  Instead, simply remove the dead code.
