Date: Tue, 11 May 1999 23:50:16 +0100 From: David Woodhouse <David.Woodhouse@mvhi.com> I've just set up a mailing list for discussion of the memory device subsystem that I've started to develop for Linux. To recap on the status: We have a basic 'mtd' layer which allows us to register low-level physical devices. The low-level devices provide simple functionality (read, write, erase block), and the mtd glue layer presents this via a character device to the user. On top of this, there can be loaded high-level drivers which attach to these devices and provide more sophisticated functionality, such as the FTL 'filesystem', which presents a block device to the user. This model (and a large amount of the code) is 'borrowed' heavily from David Hinds' code in the PCMCIA suite. Currently, we support the following physical devices...: 1. Physical memory over and above what the kernel uses. 2. M-Systems' ISA Flash disks. ... and only one high-level driver: the FTL filesystem driver. We should shortly have low-level drivers for the M-Systems DiskOnChip 2000, and I would like to resync with the PCMCIA drivers, so that PCMCIA flash devices can use the same MTD system. In discussion with David Hinds about two years ago, we decided that this system should be designed as a replacement for the PCMCIA version, with a view to removing the version in the PCMCIA code (just like the PCMCIA code doesn't have its own SCSI subsystem, etc). David - I'm not sure if that's still your intention - could you venture an opinion on the subject, please?
