x86/hvm: fix restart of RTC periodic timer with vpt_align=1
|
|
|
|
The commit 58afa7ef "x86/hvm: Run the RTC periodic timer on a
|
|
consistent time series" aligns the RTC periodic timer to the VM's boot time.
|
|
However, it's aligned later again to the system time in create_periodic_time()
|
|
with vpt_align=1. The next tick might be skipped.
