f2ccc41493 hw/timer/hpet: Fix comment about capabilities register
HPETState.capability stores the emulated value for "general capabilities
and id register" instead of "main counter register".

Fix the comment to accurately reflect this.

5fcabe628b include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST
Now that all of the Property arrays are counted, we can remove
the terminator object from each array.  Update the assertions
in device_class_set_props to match.

With struct Property being 88 bytes, this was a rather large
form of terminator.  Saves 30k from qemu-system-aarch64.

ba88935b0f hpet: place read-only bits directly in "new_val"
The variable "val" is used for two different purposes.  As an intermediate
value when writing configuration registers, and to store the cleared bits
when writing ISR.

Use "new_val" for the former, and rename the variable so that it is clearer
for the latter case.

f0ccf77078 hpet: fix and cleanup persistence of interrupt status
There are several bugs in the handling of the ISR register:

- switching level->edge was not lowering the interrupt and
  clearing ISR

- switching on the enable bit was not raising a level-triggered
  interrupt if the timer had fired

- the timer must be kept running even if not enabled, in
  order to set the ISR flag, so writes to HPET_TN_CFG must
  not call hpet_del_timer()

Commit 3787324101 ("hpet: Fix emulation of HPET_TN_SETVAL (Jan Kiszka)",
2009-04-17) applied the fix only to the low 32-bits of the comparator, but
it should be done for the high bits as well.  Otherwise, the high 32-bits
of the comparator cannot be written and they remain fixed to 0xffffffff.

ff8aff01fa hw/timer/a9gtimer: Handle QTest mode in a9_gtimer_get_current_cpu
This commit updates the a9_gtimer_get_current_cpu() function to handle
cases where QTest is enabled. When QTest is used, it returns 0 instead
of dereferencing the current_cpu, which can be NULL. This prevents the
program from crashing during QTest runs.

ad80e36744 hw, target: Add ResetType argument to hold and exit phase methods
We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

efabbc07e9 misc: pxa2xx_timer: 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.

d2f9a79a8c hw/timer/nrf51_timer: Don't lose time when timer is queried in tight loop
The nrf51_timer has a free-running counter which we implement using
the pattern of using two fields (update_counter_ns, counter) to track
the last point at which we calculated the counter value, and the
counter value at that time.  Then we can find the current counter
value by converting the difference in wall-clock time between then
and now to a tick count that we need to add to the counter value.

Unfortunately the nrf51_timer's implementation of this has a bug
which means it loses time every time update_counter() is called.
After updating s->counter it always sets s->update_counter_ns to
'now', even though the actual point when s->counter hit the new value
will be some point in the past (half a tick, say).  In the worst case
(guest code in a tight loop reading the counter, icount mode) the
counter is continually queried less than a tick after it was last
read, so s->counter never advances but s->update_counter_ns does, and
the guest never makes forward progress.

The fix for this is to only advance update_counter_ns to the
timestamp of the last tick, not all the way to 'now'.  (This is the
pattern used in hw/misc/mps2-fpgaio.c's counter.)

37d2bcbc2a hw/timer/hpet: Fix expiration time overflow
The expiration time provided for timer_mod() can overflow if a
ridiculously large value is set to the comparator register. The
resulting value can represent a past time after rounded, forcing the
timer to fire immediately. If the timer is configured as periodic, it
will rearm the timer again, and form an endless loop.

Check if the expiration value will overflow, and if it will, stop the
timer instead of rearming the timer with the overflowed time.

This bug was found by Alexander Bulekov when fuzzing igb, a new

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)
