f350982f5e target/ppc: removed VSCR from SPR registration
Since vscr is not an spr, its initialization was removed from the
spr registration functions, and moved to the relevant init_procs.

We may look into adding vscr to the reset path instead of the init
path (as suggested by David Gibson), but this looked like a good
enough solution for now.

Introduce a new POWERPC_FLAG_HID0_LE bit to indicate when
LE should be taken from HID0.  This appears to be set if
and only if POWERPC_FLAG_RTC_CLK is set, but we're not
short of bits and having both names will avoid confusion.

Note that this was the only user of hflags_nmsr, so we can
perform a straight assignment rather than mask and set.

34510e327e target/ppc: Drop use of gdb_get_float64() and ldfq_p()
We used to make a distinction between 'float64'/'float32' types and
the 'uint64_t'/'uint32_t' types, requiring special conversion
operations to go between them.  We've now dropped this distinction as
unnecessary, and the 'float*' types remain primarily for
documentation purposes when used in places like the function
prototypes of TCG helper functions.

This means that there's no need for a special gdb_get_float64()
function to write a float64 value to the GDB protocol buffer; we can
just use gdb_get_reg64().

Similarly, for reading a value out of the GDB buffer into a float64
we can use ldq_p() and need not use ldfq_p().

298091f831 target/ppc: Add E500 L2CSR0 write helper
Per EREF 2.0 [1] chapter 3.11.2:

The following bits in L2CSR0 (exists in the e500mc/e5500/e6500 core):

- L2FI  (L2 cache flash invalidate)
- L2FL  (L2 cache flush)
- L2LFC (L2 cache lock flash clear)

when set, a cache operation is initiated by hardware, and these bits
will be cleared when the operation is complete.

Since we don't model cache in QEMU, let's add a write helper to emulate
the cache operations completing instantly.

7827168471 cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClass
we cannot in principle make the TCG Operations field definitions
conditional on CONFIG_TCG in code that is included by both common_ss
and specific_ss modules.

Therefore, what we can do safely to restrict the TCG fields to TCG-only
builds, is to move all tcg cpu operations into a separate header file,
which is only included by TCG, target-specific code.

This leaves just a NULL pointer in the cpu.h for the non-TCG builds.

This also tidies up the code in all targets a bit, having all TCG cpu
operations neatly contained by a dedicated data struct.

54aa3de72e qapi: Use QAPI_LIST_PREPEND() where possible
Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND().  But places where we must keep the list in order
by appending remain open-coded until later patches.

Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
 new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

f518be3aa3 target/ppc: Remove "compat" property of server class POWER CPUs
This property has been deprecated since QEMU 5.0 by commit 22062e54bb.
We only kept a legacy hack that internally converts "compat" into the
official "max-cpu-compat" property of the pseries machine type.

According to our deprecation policy, we could have removed it for QEMU 5.2
already. Do it now ; since ppc_cpu_parse_featurestr() now just calls the
generic parent_parse_features handler, drop it as well.

Users are supposed to use the "max-cpu-compat" property of the pseries
machine type instead.

f1023d21e8 spapr: Unrealize vCPUs with qdev_unrealize()
Since we introduced CPU hot-unplug in sPAPR, we don't unrealize the
vCPU objects explicitly. Instead, we let QOM handle that for us under
object_property_del_all() when the CPU core object is finalized. The
only thing we do is calling cpu_remove_sync() to tear the vCPU thread
down.

This happens to work but it is ugly because:
- we call qdev_realize() but the corresponding qdev_unrealize() is
  buried deep in the QOM code
- we call cpu_remove_sync() to undo qemu_init_vcpu() called by
  ppc_cpu_realize() in target/ppc/translate_init.c.inc
- the CPU init and teardown paths aren't really symmetrical

The latter didn't bite us so far but a future patch that greatly
simplifies the CPU core realize path needs it to avoid a crash
in QOM.

For all these reasons, have ppc_cpu_unrealize() to undo the changes
of ppc_cpu_realize() by calling cpu_remove_sync() at the right place,
and have the sPAPR CPU core code to call qdev_unrealize().

This requires to add a missing stub because translate_init.c.inc is
also compiled for user mode.

efba15959c qom: simplify object_find_property / object_class_find_property
When debugging QEMU it is often useful to put a breakpoint on the
error_setg_internal method impl.

Unfortunately the object_property_add / object_class_property_add
methods call object_property_find / object_class_property_find methods
to check if a property exists already before adding the new property.

As a result there are a huge number of calls to error_setg_internal
on startup of most QEMU commands, making it very painful to set a
breakpoint on this method.

Most callers of object_find_property and object_class_find_property,
however, pass in a NULL for the Error parameter. This simplifies the
methods to remove the Error parameter entirely, and then adds some
new wrapper methods that are able to raise an Error when needed.

Here's my first pull request for qemu-5.2, which has quite a few
 accumulated things.  Highlights are:
 
  * Preliminary support for POWER10 (Power ISA 3.1) instruction emulation
  * Add documentation on the (very confusing) pseries NUMA configuration
  * Fix some bugs handling edge cases with XICS, XIVE and kernel_irqchip
  * Fix icount for a number of POWER registers
  * Many cleanups to error handling in XIVE code
  * Validate size of -prom-env data

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.
