2d4bd81e39 hw/rtc: Rename rtc_[get|set]_memory -> mc146818rtc_[get|set]_cmos_data
rtc_get_memory() and rtc_set_memory() helpers only work with
TYPE_MC146818_RTC devices. 'memory' in their name refer to
the CMOS region. Rename them as mc146818rtc_get_cmos_data()
and mc146818rtc_set_cmos_data() to be explicit about what
they are doing.

Mechanical change doing:

  $ sed -i -e 's/rtc_set_memory/mc146818rtc_set_cmos_data/g' \
        $(git grep -wl rtc_set_memory)
  $ sed -i -e 's/rtc_get_memory/mc146818rtc_get_cmos_data/g' \
        $(git grep -wl rtc_get_memory)

rtc_get_memory() and rtc_set_memory() methods can not take any

883f2c591f bulk: Rename TARGET_FMT_plx -> HWADDR_FMT_plx
The 'hwaddr' type is defined in "exec/hwaddr.h" as:

    hwaddr is the type of a physical address
   (its size can be different from 'target_ulong').

All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:

 $ fgrep define include/exec/hwaddr.h
 #define HWADDR_H
 #define HWADDR_BITS 64
 #define HWADDR_MAX UINT64_MAX
 #define TARGET_FMT_plx "%016" PRIx64
         ^^^^^^
 #define HWADDR_PRId PRId64
 #define HWADDR_PRIi PRIi64
 #define HWADDR_PRIo PRIo64
 #define HWADDR_PRIu PRIu64
 #define HWADDR_PRIx PRIx64
 #define HWADDR_PRIX PRIX64

Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:

$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
 #define TARGET_FMT_lx "%08x"
 #define TARGET_FMT_ld "%d"
 #define TARGET_FMT_lu "%u"
 #define TARGET_FMT_lx "%016" PRIx64
 #define TARGET_FMT_ld "%" PRId64
 #define TARGET_FMT_lu "%" PRIu64

Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:

 $ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

e896d84933 hw/rtc/mc146818rtc: Make the mc146818 RTC device target independent
The only reason for this code being target dependent was the IRQ-counting
related code in rtc_policy_slew_deliver_irq(). Since these functions have
been moved into a new, separate file (kvm_irqcount.c) which is now always
compiled and linked if necessary, we can get rid of the #ifdef TARGET_I386
switches in mc146818rtc.c and declare it in the softmmu_ss instead of
specific_ss, so that the code only gets compiled once for all targets.

These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.

While we're at it, change the apic_* prefix into kvm_* since the
functions are used from the i8259 PIC (i.e. not the APIC), too.

9598c1bb39 ptimer: Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACY
The traditional ptimer behaviour includes a collection of weird edge
case behaviours.  In 2016 we improved the ptimer implementation to
fix these and generally make the behaviour more flexible, with
ptimers opting in to the new behaviour by passing an appropriate set
of policy flags to ptimer_init().  For backwards-compatibility, we
defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old
weird behaviour.

This turns out to be a poor choice of name, because people writing
new devices which use ptimers are misled into thinking that the
default is probably a sensible choice of flags, when in fact it is
almost always not what you want.  Rename PTIMER_POLICY_DEFAULT to
PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that
new devices should not be using it.

The code-change part of this commit was produced by
  sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT)
with the exception of a test name string change in
tests/unit/ptimer-test.c which was added manually.

1f216b8ca9 qapi: Move RTC_CHANGE back out of target schema
This commit effectively reverts commit 183e4281a3, which moved
the RTC_CHANGE event to the target schema.  That change was an
attempt to make the event target-specific to improve introspection,
but the event isn't really target-specific: it's machine or device
specific.  Putting RTC_CHANGE in the target schema with an ifdef list
reduces maintainability (by adding an if: list with a long list of
targets that needs to be manually updated as architectures are added
or removed or as new devices gain the RTC_CHANGE functionality) and
increases compile time (by preventing RTC devices which emit the
event from being "compile once" rather than "compile once per
target", because qapi-events-misc-target.h uses TARGET_* ifdefs,
which are poisoned in "compile once" files.)

Move RTC_CHANGE back to misc.json.

b5bf5a53d1 Kconfig: Add I2C_DEVICES device group
Currently there is no way for a board model's Kconfig stanza to
say "I have an i2c bus which the user can plug an i2c device into,
build all the free-standing i2c devices". The Kconfig mechanism
for this is the "device group". Add an I2C_DEVICES group along
the same lines as the existing PCI_DEVICES. Simple free-standing
i2c devices which a user might plausibly want to be able to
plug in on the QEMU commandline should have
   default y if I2C_DEVICES
and board models which have an i2c bus that is user-accessible
should use
   imply I2C_DEVICES
to cause those pluggable devices to be built.

In this commit we mark only a fairly conservative set of i2c devices
as belonging to the I2C_DEVICES group: the simple sensors and RTCs
(not including PMBus devices or devices which need GPIO lines to be
connected).

qemu-common.h, but most files don't need them.  Move them to their
own header, a new include/sysemu/rtc.h.

Since the C files using these two functions did not need to include
qemu-common.h for any other reason, we can remove those include lines
when we add the include of the new rtc.h.

The license for the .h file follows that of the softmmu/rtc.c
where both the functions are defined.

1adf528ec3 hw/rtc/pl031: Send RTC_CHANGE QMP event
The PL031 currently is not able to report guest RTC change to the QMP
monitor as opposed to mc146818 or spapr RTCs. This patch adds the call
to qapi_event_send_rtc_change() when the Load Register is written. The
value which is reported corresponds to the difference between the guest
reference time and the reference time kept in softmmu/rtc.c.

For instance adding 20s to the guest RTC value will report 20. Adding
an extra 20s to the guest RTC value will report 20 + 20 = 40.

The inclusion of qapi/qapi-types-misc-target.h in hw/rtl/pl031.c
require to compile the PL031 with specific_ss.add() to avoid
./qapi/qapi-types-misc-target.h:18:13: error: attempt to use poisoned
"TARGET_<ARCH>".

fae5a04207 hw/rtc/mc146818rtc: Convert to 3-phase reset (Resettable interface)
TYPE_MC146818_RTC is an ISA device, so its DeviceClass::reset()
handler is called automatically when its qbus parent is reset
(we don't need to register it manually).

We have 2 reset() methods: a generic one and the qdev one.
Merge them into a reset_enter handler (keeping the IRQ lowering
to a reset_hold one), and remove the qemu_register_reset() call.

3ddba9a9e9 migration: Replace migration's JSON writer by the general one
Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer.  The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert.  Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer".  It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().

The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

the fallthrough is indeed wanted here, but instead of adding the

16b66c5626 goldfish_rtc: change MemoryRegionOps endianness to DEVICE_NATIVE_ENDIAN
The doc [1] doesn't define the endianness, but the kernel driver
uses readl() to access the registers, so we can guess it depends
on the architecture endianness.

As riscv architecture endianness is little it might not change anything
for it.

Moreover, android implementation uses DEVICE_NATIVE_ENDIAN [2]

b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.
