Linux MTD subsystem improvements / News: Recent posts

The new family of MTD devices is now available at GIT repository http://git.infradead.org/users/akorolev/mtd-lpddr.git

LPDDR NV-RAM - is a new generation of memory chips - non CFI, low-power, double-data-rate (LPDDR) non-volatile memory.

This snapshot contains set of patches intended to increase stability of MTD/JFFS2 subsystems and contains new features to improve JFFS2 performance, NAND perfromance, reduce JFFS2 RAM usage, provide support of special features for phase change memory. The snapshot is available here: http://downloads.sourceforge.net/mtd-mods/mtd-mods-linux-Q1-2.6.24.zip

Patch is available in next Q1 release for Linux 2.6.24.

We expect to finish development and validation by April 2008. (see updates)

Now features:
- JFFS2 large granularity: RAM usage reduction and stat time improvement
- JFFS2 mount option parsing: management of compression and granularity options
- NAND Cached read: improvement of NAND performance for large reads
- NAND partial page read: improvement of NAND performance for small reads, essentially improves JFFS2 file open/stat time.
are available for downloading and they passed whole verification cycles on M18 NOR, LP NAND, P30/P33 CFI1.5.
Also this release contains set of bug fixes for Linux 2.6.23 MTD/JFFS2
