+Real-time clock (RTC) and alarm virtualization
+**********************************************
+
+The Celadon in Virtual Machine (CiV) project may require operations on the
+RTC device, such as changes to current time and setups of alarm, to be
+synced to host and persistent across reboots. RTC device is purely emulated
+by QEMU and its state will be lost after exit of QEMU process, furthermore,
+guest RTC alarm is unable to wake up the guest after host suspends, which is
+the case in when using --host-pm-control option in CiV.
+
+The solution is to modify the emulated RTC device so that it emits QMP
+events upon certain operations and uses a QMP client running on host to
+receive the QMP events and sync the operations to host accordingly.

+
+        Figure 1 : Architecture Diagram of RTC Time Virtualization
+
+Whenever the guest RTC alarm time is set, QEMU emits an RTC_CHANGE
+event to QMP client. The QMP client can then set up a host RTC alarm
+accordingly.

+
+        Figure 2 : Architecture Diagram of RTC Alarm Virtualization
+
+Whenever the expire time of the guest RTC alarm changes, QEMU emits an
+RTC_ALARM event to the QMP client, and the QMP client can then set up a host
+RTC alarm accordingly. In the case of host suspension, the host alarm wakes
+up the host and notifies the QMP client. Then, the QMP client sends an
+rtc-refresh-timer command to QEMU, to ensure that QEMU wakes up the guest.
+
+Secure data erase
+*****************
+
+In |C|, all partitions are inside a single guest virtual disk image file on
+the host with the disk controller emulated by QEMU. The underlying actual
+storage hardware technology be it magnetic or solid state is transparent to
+the Android\* VM.
+
+As such, due to emulation, secure partition erase would be to fall back to
+“byte-by-byte overwrite” to the virtual partition. This “byte-by-byte
+overwrite” operation is not solid state storage friendly.
+
+To provide secure data erase of data partition, following enhancement is
+needed in CiV:
+
+Addition of secure data erase to make use of storage controller hardware
+secure erase feature, when it is supported in hardware to erase data
+partition and only finally fall back to byte-by-byte override 0 when not
+supported during Android recovery/wipe data process.
+
+1. Guest virtual disk image file enhancement
+
+   In CiV, all Android required partitions are resided in the same
+   guest virtual disk image file in host.
+
+   To support the enhancements to add secure data partition erase via
+   hardware controller secure erase where supported, the data partition
+   needs to be separated from the main Celadon CiV guest disk image
+   file. This allows to pass a true host partition to QEMU CiV launch
+   parameters as a separate emulated disk for secure data erase.

+        :align: center
+
+        Figure 3 : Host/Guest VM disk/file view after SDE enhancements
+        illustrates the changes in CiV guest image file in the host
+
+2. Secure data erase enhancement
+
+   In AOSP for data partition erase, this is performed by recovery tool
+   when “--wipe-data” is written to ``/cache/recovery/command``. In generic
+   AOSP data partition will have a secure partition wipe if it has
+   encryption keys for the volume before any reformatting of the
+   partition.
+
+   For SDE enhancement, to add secure erase of the data partition via
+   hardware controller feature, vsock communication between AOSP
+   recovery tool and host side daemon application is added to add data
+   partition secure erase prior to Android reformat of data partition.
+
+   The host side daemon application is added to perform secure data
+   partition wipe using hardware controller supported erase mechanism
+   such as via ``BLKSECDISCARD/BLKDISCARD`` command if supported before
+   falling back to ``BLKZEROOUT`` commands if none of the former are
+   supported.
