[Qemu-devel] [PULL 04/15] mc146818rtc: add "rtc-time" link to "/machine/rtc" |
Date: |

From: Marcelo Tosatti <address@hidden>
Add a link to rtc under /machine providing a stable
location for management apps to query the value of the
time. The link should be added by any object that sends
RTC_TIME_CHANGE events.
{"execute":"qom-get","arguments":{"path":"/machine","property":"rtc-time"} }
Suggested by Paolo Bonzini and Andreas Faerber.
