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. + +For more information please refer to: + + http://lightnvm.io + +which maintains updated FAQs, manual pages, technical documentation, tools, +contacts, etc. |
