<div class="textblock"><p>Header preceding a version 2 hierarchical deduplication table. </p>
|
||
|
|
<p>Version 2 introduces multi-level tables to efficiently address very large images by subdividing the logical address space. Tables at higher levels partition regions; leaves contain direct (block, sector) entry mappings. Navigation uses <a class="el" href="#ac8ec7921a5651b5107eda4e99b488798">tableLevel</a> (0 = root) and <a class="el" href="#a68f4825db4e22906af0e55a359360656">levels</a> (total depth).</p>
|
||
|
|
<p>Logical sector (LBA) mapping (actual implementation in decode_ddt_{single,multi}_level_v2):</p><ol type="1">
|
||
|
|
<li>Let L be the requested logical sector (can be negative externally). Internal index I = L + negative. Valid range: 0 <= I < blocks. (Total user-data sectors often = blocks - negative - overflow.)</li>
|
||
|
|
<li>If tableShift == 0 (single-level): entryIndex = I. Else (multi-level): itemsPerPrimaryEntry = 1 << tableShift primaryIndex = I / itemsPerPrimaryEntry secondaryIndex = I % itemsPerPrimaryEntry The primary table entry at primaryIndex yields a secondary DDT file offset (scaled by 2^blockAlignmentShift), whose table entries are then indexed by secondaryIndex.</li>
|
||
|
|
<li>Read raw DDT entry value E (64-bit).</li>
|
||
|
|
<li>If E == 0: sector_status = SectorStatusNotDumped; offset=block_offset=0. Otherwise extract: statusBits = E >> 60 baseBits = E & 0xFFFFFFFFFFFFFFF sectorOffsetWithinBlock = baseBits & ((1 << dataShift) - 1) blockIndex = baseBits >> dataShift block_offset (bytes) = blockIndex << blockAlignmentShift offset (sector units inside block) = sectorOffsetWithinBlock</li>
|
||
|
|
<li>The consumer combines block_offset, offset, and the (external) logical sector size to locate data.</li>
|
||
|
|
</ol>
|
||
|
|
<p>Field roles:</p><ul>
|
||
|
|
<li>negative: Count of leading negative LBAs supported; added to L to form internal index.</li>
|
||
|
|
<li>overflow: Count of trailing LBAs beyond the user area upper bound that are still dumped and have normal DDT entries (e.g. optical disc lead-out). Symmetrical to 'negative' on the high end.</li>
|
||
|
|
<li>start: For secondary tables, base internal index covered (written when creating new tables). Current decoding logic does not consult this field (future-proof placeholder).</li>
|
||
|
|
<li>blockAlignmentShift: log2 alignment of stored data blocks (byte granularity of block_offset).</li>
|
||
|
|
<li>dataShift: log2 of the number of addressable sectors per increment of blockIndex bitfield unit.</li>
|
||
|
|
<li>tableShift: log2 of number of logical sectors covered by a single primary-table pointer (multi-level only).</li>
|
||
|

</ul>

|
<p>Notes & current limitations:</p><ul>
|
||
|
|
<li>User area sector count = blocks - negative - overflow.</li>
|
||
|
|
<li>Valid external LBA range exposed by the image = [-negative, (blocks - negative - 1)].<ul>
|
||
|
|
<li>Negative range: [-negative, -1]</li>
|
||
|
|
<li>User area range: [0, (blocks - negative - overflow - 1)]</li>
|
||
|
|
<li>Overflow range: [(blocks - negative - overflow), (blocks - negative - 1)]</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>Both negative and overflow ranges are stored with normal DDT entries (if present), enabling complete reproduction of lead-in / lead-out or similar padding regions.</li>
|
||
|
|
<li>start is presently ignored during decoding; integrity checks against it may be added in future revisions.</li>
|
||
|
|
<li>No masking is applied to I besides array bounds; callers must ensure L is within representable range.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Example (Compact Disc): Disc has 360000 user sectors. Lead-in captured as 15000 negative sectors and lead-out as 15000 overflow sectors. negative = 15000 overflow = 15000 user sectors = 360000 blocks (internal span) = negative + user + overflow = 390000 External LBA spans: -15000 .. 374999</p><ul>
|
||
|
|
<li>Negative: -15000 .. -1 (15000 sectors)</li>
|
||
|
|
<li>User: 0 .. 359999 (360000 sectors)</li>
|
||
|
|
<li>Overflow: 360000 .. 374999 (15000 sectors) Internal index I for any external L is I = L + negative. User area sector count reported to callers (ctx->imageInfo.Sectors) = blocks - negative - overflow = 360000. </li>
