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