A dirty bitmap is stored using a one-level structure for the mapping to host
|
||||
clusters - an L1 table.
|
||||
The dirty bitmap described by this feature extension is stored in a set of
|
||||
clusters inside the Parallels image file. The offsets of these clusters are
|
||||
saved in the L1 offset table specified by the feature extension. Each L1 table
|
||||
entry is a 64 bit integer as described below:
|
||||
|
||||
Given an offset in bytes into the bitmap data, the offset in bytes into the
|
||||
image file can be obtained as follows:
|
||||
Given an offset in bytes into the bitmap data, corresponding L1 entry is
|
||||

offset = l1_table[offset / cluster_size] + (offset % cluster_size)

If an L1 table entry is 0, all bits in the corresponding cluster of the bitmap

are assumed to be 0.
|

If an L1 table entry is 1, the corresponding cluster of the bitmap is assumed
|

to have all bits set.
|

If an L1 table entry is 1, all bits in the corresponding cluster of the bitmap
|
||||
are assumed to be 1.
|
||||
|
||||
If an L1 table entry is not 0 or 1, it allocates a cluster from the data area.
|
||||
If an L1 table entry is not 0 or 1, it contains the corresponding cluster
|
||||
offset (in 512b sectors). Given an offset in bytes into the bitmap data the
|
||||
offset in bytes into the image file can be obtained as follows:
