302585450c tests/qtest/npcm7xx_pwm-test.c: Avoid g_assert_true() for non-test assertions
In the glib API, the distinction between g_assert() and
g_assert_true() is that the former is for "bug, terminate the
application" and the latter is for "test check, on failure either
terminate or just mark the testcase as failed".  For QEMU, g_assert()
is always fatal, so code can assume that if the assertion fails
execution does not proceed, but this is not true of g_assert_true().

In npcm7xx_pwm-test, the pwm_index() and pwm_module_index() functions
include some assertions that are just guarding against possible bugs
in the test code that might lead us to out-of-bounds array accesses.
These should use g_assert() because they aren't part of what the test
is testing and the code does not correctly handle the case where the
condition was false.

This fixes some Coverity issues where Coverity knows that
g_assert_true() can continue when the condition is false and
complains about the possible array overrun at various callsites.

Fixes: Coverity CID 1442340, 1442341, 1442343, 1442344, 1442345, 1442346

423dbce5a2 tests/qtest/ahci-test.c: Calculate iso_size with 64-bit arithmetic
Coverity notes that when calculating the 64-bit iso_size value in
ahci_test_cdrom() we actually only do it with 32-bit arithmetic.
This doesn't matter for the current test code because nsectors is
always small; but adding the cast avoids the coverity complaints.

e0c5a18efc util/compatfd.c: Replaced a malloc call with g_malloc.
Replaced a call to malloc() and its respective call to free()
with g_malloc() and g_free().

g_malloc() is preferred more than g_try_* functions, which
return NULL on error, when the size of the requested
allocation  is small. This is because allocating few
bytes should not be a problem in a healthy system.
Otherwise, the system is already in a critical state.

Subsequently, removed NULL-checking after g_malloc().

20868330a9 libqtest: refuse QTEST_QEMU_BINARY=qemu-kvm
Some downstreams rename the QEMU binary to "qemu-kvm". This breaks
qtest_get_arch(), which attempts to parse the target architecture from
the QTEST_QEMU_BINARY environment variable.

Print an error instead of returning the architecture "kvm". Things fail
in weird ways when the architecture string is bogus.

Arguably qtests should always be run in a build directory instead of
against an installed QEMU. In any case, printing a clear error when this
happens is helpful.

Since this is an error that is triggered by the user and not a test
failure, use exit(1) instead of abort(). Change the existing abort()
call in qtest_get_arch() to exit(1) too for the same reason and to be
consistent.

a67b996e78 monitor/qmp: fix race on CHR_EVENT_CLOSED without OOB
The QMP dispatcher coroutine holds the qmp_queue_lock over a yield
point, where it expects to be rescheduled from the main context. If a
CHR_EVENT_CLOSED event is received just then, it can race and block the
main thread on the mutex in monitor_qmp_cleanup_queue_and_resume.

monitor_resume does not need to be called from main context, so we can
call it immediately after popping a request from the queue, which allows
us to drop the qmp_queue_lock mutex before yielding.

e804f892b9 coverity-scan: list components, move model to scripts/coverity-scan
Place all files that can be useful to rebuild the Coverity
configuration in scripts/coverity-scan: the existing model
file, and the components setup.

The Markdown syntax was tested with Pandoc (but in any case
is meant more as a human-readable reference than as a part
of documentation).

5ecfb76ccc configure: fix detection of gdbus-codegen
"pkg-config --variable=gdbus_codegen gio-2.0" returns "gdbus-codegen",
and it does not pass test -x (which does not walk the path).

Meson 0.58.0 notices that something is iffy, as the dbus_vmstate1
assignment in tests/qtest/meson.build uses an empty string as the
command, and fails very eloquently:

../tests/qtest/meson.build:92:2: ERROR: No program name specified.

Use the "has" function instead of test -x, and fix the generation
of config-host.mak since meson.build expects that GDBUS_CODEGEN
is absent, rather than empty, if the tool is unavailable.

The ROMD mode isn't related to mapping setup.
Ideally we'd set this mode when the state machine resets,
but for now simply move it to pflash_cfi02_realize() to

This patch removes the insn16-32.decode and insn16-64.decode decode
files and consolidates the instructions into the general RISC-V
insn16.decode decode tree.

This means that all of the instructions are avaliable in both the 32-bit
and 64-bit builds. This also means that we run a check to ensure we are
running a 64-bit softmmu before we execute the 64-bit only instructions.
This allows us to include the 32-bit instructions in the 64-bit build,

3a7f7757ba fpu/softfloat: set invalid excp flag for RISC-V muladd instructions
In IEEE 754-2008 spec:
  Invalid operation exception is signaled when doing:
  fusedMultiplyAdd(0, Inf, c) or fusedMultiplyAdd(Inf, 0, c)
  unless c is a quiet NaN; if c is a quiet NaN then it is
  implementation defined whether the invalid operation exception
  is signaled.

In RISC-V Unprivileged ISA spec:
  The fused multiply-add instructions must set the invalid
  operation exception flag when the multiplicands are Inf and
  zero, even when the addend is a quiet NaN.

This commit set invalid operation execption flag for RISC-V when
multiplicands of muladd instructions are Inf and zero.

f9e580c13a target/riscv: fix exception index on instruction access fault
When no MMU is used and the guest code attempts to fetch an instruction
from an invalid memory location, the exception index defaults to a data
load access fault, rather an instruction access fault.
