2010-09-01rename crc32 to mtd_crc32Artem Bityutskiy
Because of namespace collisions mkfs.ubifs uses crc32() implementation from /lib/libz.so.1, which generates incompatible CRC and later on the kernel reports many CRC errors. Fix this by re-naming mtd-utils' crc32 function to mtd_crc32. Reported-by: Jon Povey <Jon.Povey@racelogic.co.uk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-13mtd-utils: move libmtd source files to lib/ subdirectoryKevin Cernekee
Source files for libmtd, crc32, and fec are scattered throughout the tree. Move them to a central location so they can be built into a common "libmtd.a" library used by all mtd-utils programs. This patch only renames/deletes files and does not change the content. Also modify the build system and source code so that libmtd.a can be built from a "common" location (lib/). Statically link all utilities at the top level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common crc32 implementation.

2007-08-14Switch multicast distribution system to round-robin modeDavid Woodhouse
Send one packet from each eraseblock in turn, rather than all packets for one eraseblock together. This means that bursts of loss are evenly spread between blocks. It also makes the client side a bit more complex if you can't assume that there's anywhere except the flash to store its intermediate data. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2007-08-10Fine-tine the TX timing for serve_image.David Woodhouse
It just busy-waits until it's time to send the next packet now. Which sucks, but gives us good timing for debugging. Needs work (and actually if we have hrtimers we probably _can_ sleep and still have proper timing). Signed-off-by: David Woodhouse <dwmw2@infradead.org>
