LinuxDevices.com's Rick Lehrbaum catches up with David Woodhouse, leader of the open source Memory Device Technology project, to learn more about the “bigger picture” of 2.4.0's built-in support for memory-based storage media such as the M-Systems DiskOnChip . . .

RL: I'd like to get the “bigger picture” of 2.4.0's MTD support. I was aware that there is “some” sort of MTD support in the new kernel, but I don't know how extensive it is.

Woodhouse: DiskOnChip support is now essentially fully implemented. That includes read/write, wear leveling (primitive but serviceable), and all. We support the DiskOnChip 2000 and Millennium, as well as the new DIMM because it's the same electrically as the 2000. Note, however, that the DiskOnChip support contained in 2.4.0 hasn't been widely tested yet, so it should still be considered “beta” and used with caution — especially for read/write purposes. Read-only, on the other hand, is quite useable for loading the system . . .
