2023-11-20ubiattach: introduce need_resv_pool in UBI_IOCATTZhihao Cheng
The ioctl UBI_IOCATT has been extended with need_resv_pool parameter in [1]. This parameter is used for deciding whether to reserve PEBs for filling pool/wl_pool for target ubi device. This parameter will be effective when fastmap is enabled, which will slow down the frequency of updating fastmap by filling more free PEBs in pool/wl_pool. See details in [2].

2023-11-20ubiattach: introduce disable_fm in UBI_IOCATTZhihao Cheng
The ioctl UBI_IOCATT has been extended with disable_fm parameter after [1]. This parameter is used for disabling fastmap for target ubi device. If 'disable_fm' is set, ubi doesn't create new fastmap even the module param 'fm_autoconvert' is set, and existed old fastmap will be destroyed after attaching process. A simple test case in [2].

2020-01-30libubi: remove private kernel header from includesBastian Germann
libubi.h includes ubi-media.h which was made private in the kernel a long time ago. There are users of libubi.h, e.g. swupdate, which have to have ubi-media.h available at build time with this inclusion. However, libubi.h uses only one symbol from ubi-media.h. Define that symbol in the header to enable using libubi.h without installing ubi-media.h. Make up for the transitive symbol use in ubiformat.c by including ubi-media.h.

2018-06-28libubi: add volume flags to ubi_mkvol_requestQuentin Schulz
Now that we have per-UBI volume flags (for instance for skipping CRC check when opening it) from the Linux header, let's add it to the ubi_mkvol_request in libubi and assign the flags to ubi_mkvol_req from the Linux header from ubi_mkvol.

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>
