I added a test to the gist to cover that issue. V3: Fixed starting the timer with load = 0 and counter != 0, added tests to the gist for this issue. Changed vmstate version for all VMSD's, since loadvm doesn't check version of nested VMSD. V4: Fixed spurious IT bit set for the timer starting in the periodic mode with counter = 0. Test added. V5: Code cleanup, now depends on ptimer_set_limit() fix. V6: No code change, added test to check ptimer_get_count() with corrected .limit value. V7: No change. V8: No change. ARM MPTimer tests: https://gist.github.com/digetx/dbd46109503b1a91941a Patch for ptimer is introduced since V5 of "ARM MPTimer conversion". Changelog for the "ptimer fixes" patch: V5: Only fixed ptimer_set_limit() for the disabled timer. V6: As was pointed by Peter Maydell, there are other issues beyond ptimer_set_limit(), so V6 supposed to cover all those issues. V7: Added accidentally removed !use_icount check. Added missed "else" statement. V8: Adjust period instead of the limit and do it for periodic timer only (.limit adjusting bug). Added patch/fix for freq/period change and ptimer_get_count() improvement. Dmitry Osipenko (4): hw/ptimer: Fix issues caused by the adjusted timer limit value hw/ptimer: Perform tick and counter wrap around if timer already expired hw/ptimer: Update .delta on period/freq change arm_mptimer: Convert to use ptimer hw/core/ptimer.c | 94 ++++++++++++++++++++++++----------- hw/timer/arm_mptimer.c | 110 ++++++++++++++++++----------------------- include/hw/timer/arm_mptimer.h | 4 +- 3 files changed, 115 insertions(+), 93 deletions(-) -- 2.6.4
