2018-07-09ptimer: Add TRIGGER_ONLY_ON_DECREMENT policy optionPeter Maydell1-6/+19
The CMSDK timer behaviour is that an interrupt is triggered when the counter counts down from 1 to 0; however one is not triggered if the counter is manually set to 0 by a guest write to the counter register. Currently ptimer can't handle this; add a policy option to allow a ptimer user to request this behaviour.

2018-02-09Clean up includesMarkus Armbruster1-1/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes, with the change to target/s390x/gen-features.c manually reverted, and blank lines around deletions collapsed.

2016-10-24tests: ptimer: Replace 10000 with 1Dmitry Osipenko1-28/+28
The 10000 is an arbitrarily chosen value used for advancing the QEMU time, so that ptimer's now != last. Change it to 1 to make code a bit more readable.
