Paolo Bonzini abff1abfe8 meson: target
Similar to hw_arch, each architecture defines two sourceset which are placed in
dictionaries target_arch and target_softmmu_arch.  These are then picked up
from there when building the per-emulator static_library.

Paolo Bonzini 139c1837db meson: rename included C source files to .c.inc
With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.

Alternatively you can use a fine-grained dependency, e.g.

        target/arm/translate.o: target/arm/decode-neon-shared.inc.c

With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.

The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.

Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files.  The editorconfig
file is adjusted.

Paolo Bonzini 243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

Alex Richardson dda97e385b target/mips: Fix ADD.S FPU instruction
After merging latest QEMU upstream into our CHERI fork,
I noticed that some of the FPU tests in our MIPS baremetal
testsuite [*] started failing.
It turns out commit 1ace099f2a accidentally changed add.s
into a subtract.

Huacai Chen 719d109b7f hw/mips: Implement the kvm_type() hook in MachineClass
MIPS has two types of KVM: TE & VZ, and TE is the default type. Now we
can't create a VZ guest in QEMU because it lacks the kvm_type() hook in
MachineClass. This patch add the the kvm_type() hook to support both of
the two types.

[AM: Added "if defined" guards.]

To match the actual status of Loongson insn, we split flags
for LMMI and LEXT from INSN_LOONGSON2F.

As Loongson-2F only implemented interger part of LEXT, we'll
not enable LEXT for the processor, but instead we're still using
INSN_LOONGSON2F as switch flag of these instructions.

All multimedia instructions have been moved to LMMI flag. Loongson-2F
and Loongson-3A are sharing these instructions.

Huacai Chen af868995e1 target/mips: Add Loongson-3 CPU definition
Loongson-3 CPU family include Loongson-3A R1/R2/R3/R4 and Loongson-3B
R1/R2. Loongson-3A R1 is the oldest and its ISA is the smallest, while
Loongson-3A R4 is the newest and its ISA is almost the superset of all
others. To reduce complexity, we just define two CPU types:

1) "Loongson-3A1000" CPU which is corresponding to Loongson-3A R1. It is
   suitable for TCG because Loongson-3A R1 has fewest ASE.
2) "Loongson-3A4000" CPU which is corresponding to Loongson-3A R4. It is
   suitable for KVM because Loongson-3A R4 has the VZ ASE.

Loongson-3A has CONFIG6 and CONFIG7, so add their bit-fields as well.

Peter Maydell 781c67ca55 cpu: Use DeviceClass reset instead of a special CPUClass reset
The CPUClass has a 'reset' method.  This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE.  We don't need it any
more, as we can simply use the TYPE_DEVICE reset.  The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.

This change should not cause CPU objects to be reset more often
than they are at the moment, because:
 * nobody is directly calling device_cold_reset() or
   qdev_reset_all() on CPU objects
 * no CPU object is on a qbus, so they will not be reset either
   by somebody calling qbus_reset_all()/bus_cold_reset(), or
   by the main "reset sysbus and everything in the qbus tree"
   reset that most devices are reset by

Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.

All the changes to the files under target/ were made using the
included Coccinelle script, except:

(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
  perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c

(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:

| @@ -96,8 +96,9 @@ static void s390_cpu_reset(CPUState *s, cpu_reset_type type)
|     S390CPU *cpu = S390_CPU(s);
|     S390CPUClass *scc = S390_CPU_GET_CLASS(cpu);
|     CPUS390XState *env = &cpu->env;

Alex Bennée a010bdbe71 gdbstub: extend GByteArray to read register helpers
Instead of passing a pointer to memory now just extend the GByteArray
to all the read register helpers. They can then safely append their
data through the normal way. We don't bother with this abstraction for
write registers as we have already ensured the buffer being copied
from is the correct size.

Alex Richardson ec860426df target/mips: Fix handling of LL/SC instructions after 7dd547e5ab
After 7dd547e5ab the env->llval value
is loaded as an unsigned value (instead of sign-extended as before).
Therefore, the CMPXCHG in gen_st_cond() in translate.c fails if the
sign bit is set in the loaded value.

Fix this by sign-extending the llval value for the 32-bit case.

I discovered this issue because FreeBSD MIPS64 was looping forever
in an atomic helper function when trying to start /sbin/init.
