Hi,
The following patches introduce the support of the dirty bitmap logging and
dumping to a specified file. This patch addresses the previous issues raised
by David and Juan. Since, I have not received any comments on the runstates,
I'll keep them in the patch series.
v3 --> v4
* Added new qmp interface for information extraction from the bitmap process
v2 --> v3
* Reformatted the code and removed some unnecessary parts.
* Printing block info along with length and offset.
* Changed the functions that were directly using RUN_STATE_RUNNING as state.
v1 --> v2:
* Added two new run states to avoid simultaneous execution of both migration and
bitmap dump process.
* Removed FILE pointer usage.
* Dumping the data only in machine-readable format.
* Tried to rectify mistakes of the previous version.
Sanidhya Kashyap (8):
enable sharing of the function between migration and bitmap dump
RunState: added two new flags for bitmap dump and migration process
BitmapLog: bitmap dump code via QAPI framework with runstates
BitmapLog: hmp interface for dirty bitmap dump
BitmapLog: cancel mechanism for an already running dump bitmap process
BitmapLog: set the frequency of the dump bitmap process
BitmapLog: get the information about the parameters
BitmapLog: python script for extracting bitmap from a binary file
