mtd-utils.git/ubi-utils/include, branch v2.1.1

Move ubi-utils libraries to common library location

2016-11-17T10:36:56+00:00

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

Merge rest of ubiutils-common into libmtd common

2016-11-17T10:36:56+00:00

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.

Remove unused ubiutils_print_text from ubi-utils common

2016-11-17T10:36:56+00:00

The function ubiutils_print_text was previously used by ubinize to pretty-print parts of the help text. Since the help text has been moved to a man page, the function is no longer used/needed. Signed-off-by: David Oberhollenzer

ubi-utils: Add ubiblock tool

2014-03-25T07:54:48+00:00

With the addition of block device access to UBI volumes, we now add a simple userspace tool to access the new ioctls. Usage of this tool is as simple as it gets: $ ubiblock --create /dev/ubi0_0 will create a new block device /dev/ubiblock0_0, and $ ubiblock --remove /dev/ubi0_0 will remove the device. Artem: slightly changed the header comment. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy

ubiattach: fail if kernel ignores max_beb_per1024

2012-08-23T09:48:54+00:00

If the kernel doesn't know the max_beb_per1024 parameter in the attach ioctl, but the call still succeeded ubi_attach and ubi_attach_mtd will return 1 instead of 0. In this case, the ubiattach command will detach the device and fail with an error message. Signed-off-by: Richard Genoud Signed-off-by: Artem Bityutskiy

ubiattach: introduce max_beb_per1024 in UBI_IOCATT

2012-08-23T09:16:10+00:00

The ioctl UBI_IOCATT has been extended with max_beb_per1024 parameter. This parameter is used for adjusting the "maximum expected number of bad blocks per 1024 blocks" for each mtd device. The number of physical erase blocks (PEB) that UBI will reserve for bad block handling is now: whole_flash_chipset__PEB_number * max_beb_per1024 / 1024 This means that for a 4096 PEB NAND device with 3 MTD partitions: mtd0: 512 PEB mtd1: 1536 PEB mtd2: 2048 PEB the commands: ubiattach -m 0 -d 0 -b 20 /dev/ubi_ctrl ubiattach -m 1 -d 1 -b 20 /dev/ubi_ctrl ubiattach -m 2 -d 2 -b 20 /dev/ubi_ctrl will attach mtdx to UBIx and reserve: 80 PEB for bad block handling on UBI0 80 PEB for bad block handling on UBI1 80 PEB for bad block handling on UBI2 => for the whole device, 240 PEB will be reserved for bad block handling. This may seems a waste of space, but as far as the bad blocks can appear every where on a flash device, in the worst case scenario they can all appear in one MTD partition. So the maximum number of expected erase blocks given by the NAND manufacturer should be reserve on each MTD partition. Signed-off-by: Richard Genoud Signed-off-by: Artem Bityutskiy

libubi: kill ubi_attach_mtd

2012-08-23T08:37:05+00:00

The 'ubi_attach_mtd()' is not used and it is redundant now. 'ubi_attach()' function may be used instead. Signed-off-by: Artem Bityutskiy

libubi: factorize ubi_attach and ubi_attach_mtd code

2012-08-23T08:31:36+00:00

The req->mtd_num value is now updated with the MTD device number found by mtd_node_to_num. Signed-off-by: Richard Genoud Signed-off-by: Artem Bityutskiy

UBI: sync ubi-user.h with kernel v3.6-rc1

2012-08-22T10:20:49+00:00

Also remove the eraseblock type support, because kernel commit a65a0eb6d198e058687a9214683bd1c418f20d39 set the dtype parameter as obsolete. Also adjust to some renames: * 'UBI_PROP_DIRECT_WRITE' -> 'UBI_VOL_PROP_DIRECT_WRITE' * 'struct ubi_set_prop_req' -> 'struct ubi_set_vol_prop_req'. * 'UBI_IOCSETPROP' -> 'UBI_IOCSETVOLPROP' Signed-off-by: Richard Genoud Signed-off-by: Artem Bityutskiy
