2021-09-06Add ubiscan utilityDiego Ismirlian
ubiscan will scan the PEBs in a specific MTD device and print a summary of the PEB erase counters and (optionally) details about each PEB's status. Example output: # ./ubiscan /dev/mtd6 Summary ========================================================= mtd : 6 type : nand size : 110362624 bytes (105.2 MiB) PEBs : 842 min I/O: 2048 bytes PEB erase counters ========================================================= valid : 834 empty : 0 corrupted: 0 alien : 0 bad : 8 Histogram ========================================================= from to count min avg max --------------------------------------------------------- 0 .. 9: 55 1 4 9 10 .. 99: 174 10 48 99 100 .. 999: 514 103 287 987 1000 .. 9999: 91 1004 1880 2251 10000 .. 99999: 0 0 0 0 100000 .. inf: 0 0 0 0 --------------------------------------------------------- Total : 834 1 392 2251 If the --verbose switch is given, ubiscan will print PEB details: # ./ubiscan --verbose /dev/mtd6 [... same output as before ...] Details ========================================================= PEB 0: 253 PEB 1: 1489 PEB 2: 1 PEB 3: 1 PEB 4: 1 PEB 5: 1 PEB 6: 1 PEB 7: 1 PEB 8: 1 PEB 9: 1 PEB 10: 1 ...

2021-01-20Cleanup: Automake: remove single use variablesDavid Oberhollenzer
Throughout the Automake files, there is a consistent pattern somewhat like this: FOO_BINS = .... sbin_PROGRAMS += $(FOO_BINS) This commit all such patterns whenever the variable is not used anywhere else and appends to the target directly.

2021-01-20Remove headers from EXTRA_DISTDavid Oberhollenzer
This commit removes the C header files from the EXTRA_DIST variables and instead assigns them to the SOURCE variable of the respective components they belong to. This takes care of having them distributed in the release tar ball and helps with dependency tracking a little. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-12-08ubihealthd: Build only if sys/random.h is presentMarek Vasut
The ubihealthd depends on sys/random.h , which is not present on some older systems. Build ubihealthd only if sys/random.h is present. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-25ubi-utils: Implement a ubihealthdRichard Weinberger
ubihealthd is a simple daemon which scans every PEB of an UBI device in random order. It helps to deal with read disturb on systems which either reboot seldom, use fastmap or read few data. To use this daemon you need Linux >= v5.1. Signed-off-by: Richard Weinberger <richard@nod.at>
2016-11-17Move ubi-utils libraries to common library locationDavid Oberhollenzer
Historically, the mtd-utils and ubi-utils were seperate packages. The ubi-utils were at some point merged into the mtd-utils. They first appeared in the release tar-ball in version 1.1.0 in their own sub-hirarchy with their own buildsystem, readme, documentation, etc. A lot of the duplicated stuff got centralized/removed over time. This patch further cleans up the directory hirarchy duplication by moving common libraries from the ubi-utils/ into the central lib/ and include/ directories in the top directory of the mtd-utils package. This includes: - libuib.a & libubigen.a used by the ubi utilities - libscan.a currently only used by ubiformat - libiniparser.a used by ubinize Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2016-11-17Merge rest of ubiutils-common into libmtd commonDavid Oberhollenzer
This patch moves the remaining 3 functions from ubiutils-common.{c,h} into libmtd common.{c,h}. The functions are only generic utility functions that other mtd-utils programs may also find usefull and every program that uses libubi links against libmtd anyway so there is no real reason for keeping around a seperate ubiutils-common with only generic helper functions.

2016-11-17Add ubinize manpageDavid Oberhollenzer
This patch removes the lengthy help text from the ubinize utility that attempted to describte the file format and every minor detail, and reformats it into a more readable man page. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2016-11-17Change build system to autotoolsRichard Weinberger
This patch is largely based on Richards original RFC. The major differences to the RFC patch are: - Add missing sumtools & mtdpart targets - Fix name of mkfs.jffs2 target - Add missing subdir-objects option for non-recursive make - Move all automake options to configure.ac - Add manpages to install target - Make XATTR & LZO support configurable - Install binaries to sbin directory like in the old build system - Install flash_erase wrapper script - Add files missing from distribution target Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at> Signed-off-by: Richard Weinberger <richard@nod.at>
