The current Debug exception dispatch is the BookE one, so it is
different from the 405. We effectively don't support the 405 Debug
exception.
This patch removes the BookE code and moves the DEBUG into the "not
implemented" block.
Note that there is in theory a functional change here since we now
abort when a Debug exception happens. However, given how it was never
implemented, I don't believe this to have ever been dispatched for the
405.

spapr_get_fw_dev_path() is an impl of
FWPathProviderClass::get_dev_path(). This interface is used by
hw/core/qdev-fw.c via fw_path_provider_try_get_dev_path() in two
functions:
- static char *qdev_get_fw_dev_path_from_handler(), which is used only in
qdev_get_fw_dev_path_helper() and it's guarded by "if (dev &&
dev->parent_bus)";
- char *qdev_get_own_fw_dev_path_from_handler(), which is used in
softmmu/bootdevice.c in get_boot_device_path() like this:
if (dev) {
d = qdev_get_own_fw_dev_path_from_handler(dev->parent_bus, dev);
This means that, when called via softmmu/bootdevice.c, there's no check
of 'dev->parent_bus' being not NULL. The result is that the "BusState
*bus" arg of spapr_get_fw_dev_path() can potentially be NULL and if, at
the same time, "SCSIDevice *d" is not NULL, we'll hit this line:
void *spapr = CAST(void, bus->parent, "spapr-vscsi");
And we'll SIGINT because 'bus' is NULL and we're accessing bus->parent.
Adding a simple 'bus != NULL' check to guard the instances where we
access 'bus->parent' can avoid this altogether.

cpu_interrupt_exittb() was introduced by commit 044897ef4a
("target/ppc: Fix system lockups caused by interrupt_request state
corruption") as a way to wrap cpu_interrupt() helper in BQL.
After that, commit 6d38666a89 ("ppc: Ignore the CPU_INTERRUPT_EXITTB
interrupt with KVM") added a condition to skip this interrupt if we're
running with KVM.
Problem is that the change made by the above commit, testing for
!kvm_enabled() at the start of cpu_interrupt_exittb():
static inline void cpu_interrupt_exittb(CPUState *cs)
{
if (!kvm_enabled()) {
return;
}
(... do cpu_interrupt(cs, CPU_INTERRUPT_EXITTB) ...)
is doing the opposite of what it intended to do. This will return
immediately if not kvm_enabled(), i.e. it's a emulated CPU, and if
kvm_enabled() it will proceed to fire CPU_INTERRUPT_EXITTB.
Fix the 'skip KVM' condition so the function is a no-op when
kvm_enabled().

pnv_phb4_translate_tve() is quite similar to pnv_phb3_translate_tve(),
and that includes the fact that 'taddr' can be considered uninitialized
when throwing the "TCE access fault" error because, in theory, the loop
that sets 'taddr' can be skippable due to 'lev' being an signed int.
No one complained about this specific case yet, but since we took the
time to handle the same situtation in pnv_phb3_translate_tve(), let's
replicate it here as well.

The 'taddr' variable is left unintialized, being set only inside the
"while ((lev--) >= 0)" loop where we get the TCE address. The 'lev' var
is an int32_t that is being initiliazed by the GETFIELD() macro, which
returns an uint64_t.
For a human reader this means that 'lev' will always be positive or zero.
But some compilers may beg to differ. 'lev' being an int32_t can in theory
be set as negative, and the "while ((lev--) >= 0)" loop might never be
reached, and 'taddr' will be left unitialized. This can cause phb3_error()
to use 'taddr' uninitialized down below:
if ((is_write & !(tce & 2)) || ((!is_write) && !(tce & 1))) {
phb3_error(phb, "TCE access fault at 0x%"PRIx64, taddr);
A quick way of fixing it is to use a do/while() loop. This will keep the
same semanting as the existing while() loop does and the compiler will
understand that 'taddr' will be initialized at least once.

After a TLB miss exception, GPRs 0-3 must be restored on rfi.
This is managed by hreg_store_msr() which is called by do_rfi()
However, hreg_store_msr() does it if MSR[TGPR] is unset in the
passed MSR value.
The problem is that do_rfi() is given the content of SRR1 as
the value to be set in MSR, but TGPR bit is not part of SRR1
and that bit is used for something else and is sometimes set
to 1, leading to hreg_store_msr() not restoring GPRs.
So, do the same way as for POW bit, force clearing it.

early anyway. As nothing enforces LE anywhere, this drops it for VOF.

In some cases, a particular mapcache entry may be mapped 256 times
causing the lock field to wrap to 0. For example, this may happen when
using emulated NVME and the guest submits a large scatter-gather write.
At this point, the entry map be remapped causing QEMU to write the wrong
data or crash (since remap is not atomic).
Avoid this overflow by increasing the lock field to a uint32_t and also
detect it and abort rather than continuing regardless.

commit f37f29d314 "xen: slightly simplify bufioreq handling" hard
coded setting req.count = 1 during initial field setup before the main
loop. This missed a subtlety that an early exit from the loop when
there are no ioreqs to process, would have req.count == 0 for the return
value. handle_buffered_io() would then remove state->buffered_io_timer.
Instead handle_buffered_iopage() is basically always returning true and
handle_buffered_io() always re-setting the timer.
Restore the disabling of the timer by introducing a new handled_ioreq
boolean and use as the return value. The named variable will more
clearly show the intent of the code.

We don't generate trace events for tests/ and qga/ because that it is
not simple and not necessary. We have corresponding comments in both
tests/meson.build and qga/meson.build.
Still to not miss possible future qapi code generation call, and not to
forget to enable trace events generation, let's enable it by default.
So, turn option --gen-trace into opposite --no-trace-events and use new
option only in tests/ and qga/ where we already have good comments why
we don't generate trace events code.
Note that this commit enables trace-events generation for qapi-gen.py
call from tests/qapi-schema/meson.build and storage-daemon/meson.build.
Still, both are kind of noop: tests/qapi-schema/ doesn't seem to
generate any QMP command code and no .trace-events files anyway,
storage-daemon/ uses common QMP command implementations and just
generate empty .trace-events

Making trace generation work for tests/ and qga/ would involve some
Meson hackery to ensure we generate the trace-events files before
trace-tool uses them. Since we don't actually support tracing there
anyway, we bypass that problem.
Let's add corresponding comments.
