1 | pblk: Physical Block Device Target |
2 | ================================== | |
3 | ||
4 | pblk implements a fully associative, host-based FTL that exposes a traditional | |
5 | block I/O interface. Its primary responsibilities are: | |
6 | ||
7 | - Map logical addresses onto physical addresses (4KB granularity) in a | |
8 | logical-to-physical (L2P) table. | |
9 | - Maintain the integrity and consistency of the L2P table as well as its | |
10 | recovery from normal tear down and power outage. | |
11 | - Deal with controller- and media-specific constrains. | |
12 | - Handle I/O errors. | |
13 | - Implement garbage collection. | |
14 | - Maintain consistency across the I/O stack during synchronization points. | |
