2012-08-23ubiattach: introduce max_beb_per1024 in UBI_IOCATTRichard Genoud
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.

2012-02-02mtdinfo: fix `--all' for non-consecutive device numbersBrian Norris
When we have assigned non-consecutive device numbers to our MTD devices, then we run `mtdinfo --all', we get errors once mtdinfo tries to process the devices in the "hole". For instance, suppose that at boot time, we have one MTD (/dev/mtd0) then perform a sequence like the following: # modprobe mtdram # modprobe nandsim # rmmod mtdram Then at this point, we have should have devices 0 and 2 without 1. Then: # mtdinfo --all ... mtdinfo: error!: mtd1 does not correspond to any existing MTD device We add a check to first see if device is present, then continue to the next ID if it doesn't exist.

When we have assigned non-consecutive device numbers to our UBI devices, then we run `ubinfo --all', we get errors once ubinfo tries to process the devices in the "hole". For instance, suppose there are two UBI devices, /dev/ubi0 and /dev/ubi10; then, ubinfo will fail trying to open /dev/ubi1 with: ubinfo: error!: cannot get information about UBI device 1 error 2 (No such file or directory) This patch adds a check to first see if device is present, then continue to the next ID if it doesn't exist.

2011-11-18mtdinfo: provide info when used without argumentsBrian Norris
If the user specifies neither a MTD argument nor the `-a' flag, we print a cryptic message; i.e., # mtdinfo libmtd: error!: cannot get information about "(null)" error 14 (Bad address) mtdinfo: error!: cannot get information about MTD device "(null)" error 14 (Bad address) This is a regression; previously, mtdinfo would give some short info about number of devices, etc. when used without arguments. To fix this, we revert commit d53c03b0989f8354a7e4dbb947a150fc7fe3f6d1 and call print_general_info() when no device is specified.

2011-09-19ubiformat: handle write errors correctlyArtem Bityutskiy
This issue was reported and analyzed by Anton Olofsson <anol.martinsson@gmail.com>: when ubiformat encounters a write error while flashing the UBI image (which may come from a file of from stdout), it correctly marks the faulty eraseblock as bad and skips it. However, it also incorrectly drops the data buffer which was supposed to be written, and reads next block of data. This patch fixes this issue - in case of a write error, we preserve the current data and write it to the next eraseblock, instead of dropping it.

2011-08-16mtdinfo: don't open NULL pointer when getting region_info with `-a'Brian Norris
This "fixes" a regression found in: commit 266061ebd5d72391f0a0e831b018e8fc7fea68a1 mtdinfo: add regioninfo/eraseblock map display On certain flash (NOR flash that have eraseblock region info), `mtdinfo -a' tries to open the MTD node file, for use with the ioctl MEMGETREGIONINFO; however, we didn't supply a device node path to `mtdinfo -a', so it's using NULL, resulting in errors like: mtdinfo: error!: couldn't open MTD dev: (null) error 14 (Bad address) For now, we can just skip dumping region_info with the `-a' flag. If we find a better way to do this (e.g., export via sysfs, find device nodes via automatic routines, etc.), then we can kill the workaround and this FIXME should be removed. The regression was first reported at: http://lists.infradead.org/pipermail/linux-mtd/2011-July/037232.html The result of recent changes is that we cannot get region_info for devices via the `--all' option. We add a note in the help message warning that mtdinfo may find more info when given a device patch, e.g., /dev/mtdX.

2011-06-27rewrite build system to avoid recursionMike Frysinger
The ubi-utils/src/ subdir is tossed as it just complicates things for no real gain. The dictionary.h header is relocated to the ubi-utils/include/ since other headers in there need it. The top level clean is replaced with a `find -delete` on objects, so it might prune more than necessary, but many projects now do this sort of thing and no one complained there. A "mkdep" helper generates the actual rule, and the variables are used with "foreach" to expand these automatically. The tests subdir is updated only to reflect the ubi-utils source move. Otherwise, it is left untouched as making that non-recursive isn't really worth the effort. While we're gutting things, also through in kbuild style output while building to make things more legible.

2010-07-26libmtd: support MEMERASE64Artem Bityutskiy
This patch is base on Kevin Cernekee's patch posted to the MTD mailing list. It adds MEMERASE64 support to the 'mtd_erase()' call. Now it first tries to use MEMERASE64, and if that is not supported, falls back to the old MEMERASE ioctl. This patch also introduces an 'offs64_ioctl' flag to the libmtd descriptor. However, we cannot initialize it in 'libmtd_open()', because we need an MTD device node, which we do not have in 'libmtd_open()'. Thus, we firs mark this flag as "uninitialized", and at the first invocation of 'mtd_erase()' we initialize it. This also means that we have to pass the limbtd descriptor to 'mtd_erase()', to save the flag value. This, in turn, requires tweaking 'mtd_erase()' users. This is not very nice, but good enough so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
