[Qemu-devel] [PATCHv3 0/9] pseries: Fix and extend PAPR RTC implementation

[David Gibson]

At the moment, the PAPR RTC implementation (actually a paravirt
firmware interface, rather than a normal device) works directly off
host time, and so doesn't respect the options such as clock=vm which
can be specified in the -rtc command line option.  This series
addresses those defects.

The above makes it clearer that the spapr RTC should probably be its
own separate qdev, so this series also implements that.

Finally it moves the code from mc146818rtc for publishing the RTC time
via QOM into generic QOM helpers, and extends the PAPR RTC driver to
export in a similar way.

Changes since v2:
  * We still need the rtc_offset field in sPAPREnvironment to handle
    incoming migrations from older versions, but we no longer send it
    for outgoing migrations.
Changes since v1:
  * Actually create a qdev device for the PAPR RTC
    * Instead of duplicating the QOM publishing code from mc146818, move
        it into a generic helper
        

*** BLURB HERE ***

David Gibson (9):
  Generalize QOM publishing of date and time from mc146818rtc.c

  pseries: Add spapr_rtc_read() helper function
  pseries: Make RTAS time of day functions respect -rtc options
  pseries: Make the PAPR RTC a qdev device
  pseries: Move rtc_offset into RTC device's state structure
  pseries: Export RTC time via QOM
