Peter Maydell fd7f95f23d hw/rtc/sun4v-rtc: Relicense to GPLv2-or-later
The sun4v RTC device model added under commit a0e893039c in 2016
was unfortunately added with a license of GPL-v3-or-later, which is
not compatible with other QEMU code which has a GPL-v2-only license.

Relicense the code in the .c and the .h file to GPL-v2-or-later,
to make it compatible with the rest of QEMU.

Jessica Clarke 4d28d57c9f pl031: Update last RTCLR value on write in case it's read back
The PL031 allows you to read RTCLR, which is meant to give you the last
value written. PL031State has an lr field which is used when reading
from RTCLR, and is present in the VM migration state, but we never
actually update it, so it always reads as its initial 0 value.

Abhiram Tilak 9d80aa0483 misc: m48t59: replace qemu_system_reset_request() call with watchdog_perform_action()
A few watchdog devices use qemu_system_reset_request(). This is not ideal since
behaviour of watchdog-expiry can't be changed by QMP using `watchdog_action`.
As stated in BiteSizedTasks wiki page, instead of using qemu_system_reset_request()
to reset when a watchdog timer expires, let watchdog_perform_action() decide
what to do.

Peter Maydell c0a6385728 hw/rtc/aspeed_rtc: Use 64-bit offset for holding time_t difference
In the aspeed_rtc device we store a difference between two time_t
values in an 'int'. This is not really correct when time_t could
be 64 bits. Enlarge the field to 'int64_t'.

This is a migration compatibility break for the aspeed boards.
While we are changing the vmstate, remove the accidental
duplicate of the offset field.

Philippe Mathieu-Daudé 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)

Thomas Huth 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.

Peter Maydell 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.

Bernhard Beschow 215caca6bf hw/isa: Inline and remove one-line isa_init_irq()
isa_init_irq() has become a trivial one-line wrapper for isa_get_irq().
It can therefore be removed.

Bernhard Beschow e89d9fa385 hw/rtc/m48t59-isa: QOM'ify IRQ number
Exposing the IRQ number as a QOM property not only allows it to be
configurable but also to be printed by standard QOM mechanisms. This allows
isabus_dev_print() to be retired eventually.

Bernhard Beschow 3b004a1654 hw/rtc/mc146818rtc: QOM'ify IRQ number
Exposing the IRQ number as a QOM property not only allows it to be
configurable but also to be displayed in HMP:

Before:

(qemu) info qtree
       ...
          dev: mc146818rtc, id ""
            gpio-out "" 1
            base_year = 0 (0x0)
            lost_tick_policy = "discard"

After:

          dev: mc146818rtc, id ""
            gpio-out "" 1
            base_year = 0 (0x0)
            irq = 8 (0x8)
            lost_tick_policy = "discard"

The reason the IRQ number didn's show up before is that this device does not
call isa_init_irq().

Markus Armbruster 2beb1e5f9a rtc: Have event RTC_CHANGE identify the RTC by QOM path
Event RTC_CHANGE is "emitted when the guest changes the RTC time" (and

Which one changed?  New @qom-path identifies it.

Peter Maydell 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.

Peter Maydell 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).

Peter Maydell 2f93d8b04a rtc: Move RTC function prototypes to their own header
softmmu/rtc.c defines two public functions: qemu_get_timedate() and
qemu_timedate_diff().  Currently we keep the prototypes for these in
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.

Eric Auger 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

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.
