ext2load: increase read speed 2012-06-21T20:49:33+00:00 u-boot@lakedaemon.net u-boot@lakedaemon.net 2012-03-28T04:37:11+00:00 436da3cd233e7166b5ce9293dbd28092cf37bcc9 This patch dramatically drops the amount of time u-boot needs to read a file from an ext2 partition. On a typical 2 to 5 MB file (kernels and initrds) it goes from tens of seconds to a couple seconds. All we are doing here is grouping contiguous blocks into one read. Boot tested on Globalscale Technologies Dreamplug (Kirkwood ARM SoC) with three different files. sha1sums were calculated in Linux userspace, and then confirmed after ext2load.

ext2fs: Fix optimization bug for doubly-indirect block pointers 2010-08-07T20:44:08+00:00 Aaron Pace Aaron.Pace@alcatel-lucent.com 2010-07-26T20:24:44+00:00 a2740dd00da52874d71269eaa06cf4bde549d2fe Doubly-indirect block numbers are compared against the first-level indirect block when checking for a cached copy. This is causing the doubly-indirect block to be re-read each time it is accessed. Repairing this reduces load time for a 70M file from 72 seconds to 38 seconds.

EXT2FS: fix inode size for ext2fs rev#0 2009-12-04T23:46:10+00:00 Michael Brandt Michael.Brandt@emsyso.de 2009-11-22T13:13:27+00:00 270737acca21f3939f814de5dcf350a1c3d80d83 extfs.c assumes that there is always a valid inode_size field in the superblock. But this is not true for ext2fs rev 0. Such ext2fs images are for instance generated by genext2fs. Symptoms on ARM machines are messages like: "raise: Signal # 8 caught"; on PowerPC "ext2ls" will print nothing. This fix checks for rev 0 and uses then 128 bytes as inode size.
