Unify handling of configure switches

2024-02-19T08:04:00+00:00

Remove the strict check of the with or enable value and use the generated variable instead of our own. Also, don't use WITH_GETRANDOM as an implicit WITH_UBIHEALTHD, split the two autoconf/automake variables and handle them separately. Signed-off-by: David Oberhollenzer

ubiattach: introduce need_resv_pool in UBI_IOCATT

2023-11-20T06:43:34+00:00

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].

ubiattach: introduce disable_fm in UBI_IOCATT

2023-11-20T06:43:30+00:00

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].

Fix printf format specifiers for 64 bit integer types

2023-08-24T08:30:28+00:00

In nandflipbits, nandtest and ubiscan, uint64_t integers are printed to stdout using "%llu" as a format specifier, but on platforms like x86_64, uint64_t is actually typedef'd as `unsigned long` only. For compatibillity across platforms, simply use the C99 printfs macros instead. Signed-off-by: David Oberhollenzer

Make sure ubi-media structures are visible for libubigen

2023-08-24T08:02:59+00:00

The libubigen.h header relies on external declarations in ubi-media.h. While not technically needed, it generates warnings in mtdinfo.c if those are not visible. All other places where libubigen is used include the header first. This is primarily to silence compiler warnings related to the missing declrations. Signed-off-by: David Oberhollenzer

mtd-utils: Add new syntax to get devices by name

2023-05-30T09:12:12+00:00

This introduces a new feature to the MTD command line utilities that allows MTD devices to be referenced by name instead of device node. For example this looks like: > # Display info for the MTD device with name "data" > mtdinfo mtd:data > # Copy file to MTD device with name "data" > flashcp /my/file mtd:data This follows the syntax supported by the kernel which allows MTD device's to be mounted by name[1]. Add the function mtd_find_dev_node() that accepts an MTD "identifier" and returns the MTD's device node. The function accepts a string starting with "mtd:" which it treats as the MTD's name. It then attempts to search for the MTD, and if found maps it back to the /dev/mtdX device node. If the string does not start with "mtd:", then assume it's the old style and refers directly to a MTD device node. The function is then hooked into existing tools like flashcp, mtdinfo, flash_unlock, etc. To load in the new MTD parsing code in a consistent way across programs.

ubinfo: Fix --vol_id return code for absent volume id

When using --vol_id and that volume is missing, it should return non-zero like the --name option does. Signed-off-by: Andrew Mellor Signed-off-by: David Oberhollenzer

Add ubiscan utility

2021-09-06T06:21:00+00:00

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 ...

Cleanup: Automake: remove single use variables

2021-01-20T10:53:58+00:00

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. Signed-off-by: David Oberhollenzer
