Hello,
Currently, QEMU ARM MPTimer device model provides only a certain subset of
the emulation behavior. This patch series is supposed to add missing parts by
converting the MPTimer to use generic ptimer helper. It fixes some important
ptimer bugs and provides new features that are required for the ARM MPTimer.
Changelog:
V15: As per Peter's Maydell request: split ptimer policy patches,
so that first "policy" patch only sets default policy to all
of the timers without introducing new behaviour policies.
The "deferred trigger" ptimer policy from V14 is converted to
"continuous trigger" as it is more intuitive.
New ptimer policies added.
New ptimer patch "Actually stop timer in case of error".
Fixed ARM MPTimer periodic/oneshot "on the fly" mode switch
for the case when load = 0 and new mode has prescaler = 0.
Added QTests for each of the ptimer policies.
Added QTests for the ARM MPTimer.
V14: Set the ptimer policy in the ptimer_init() instead of adding
ptimer_set_policy(), keeping ptimer VMState unchanged and dropped
hw_error() hardening asserts as per Peter's Maydell V13 review
comments, addressed the rest of the review comments.
