7cc9aa66 - mtd: Add sysfs attribute for mtd OOB available size

Mon, 02 Apr 2018 08:20:10 +0000

mtd: Add sysfs attribute for mtd OOB available sizeExpose mtd OOB available size by sysfs file.

7d84120b - Documentation: ABI: mtd: describe "offset" more precisely

Sun, 25 Jun 2017 11:11:54 +0000

Documentation: ABI: mtd: describe "offset" more preciselySo far Linux supported only two levels of MTD devices so we didn't needa very precise description for this sysfs file. With commit97519dc52b44a ("mtd: partitions: add support for subpartitions") thereis support for a tree structure so we should have more precisedescription. Using "parent" and "flash device" makes it more accurate.Signed-off-by: Rafał Miłecki Signed-off-by: Brian Norris List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-mtd

a62c24d7 - mtd: part: Add sysfs variable for offset of partition

Thu, 02 Apr 2015 22:15:11 +0000

mtd: part: Add sysfs variable for offset of partitionThis patch makes a sysfs variable called 'offset' on each partitionwhich contains the offset in bytes from the beginning of the masterdevice that the partition starts.Signed-off-by: Dan Ehrenberg Signed-off-by: Brian Norris List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-mtd

990a3af0 - mtd: Add sysfs attributes to expose the ECC stats fields

Tue, 24 Jun 2014 13:55:50 +0000

mtd: Add sysfs attributes to expose the ECC stats fieldsThese new sysfs device attributes allow us to retrieve the ECC and badblock stats by poking a sysfs file, which is often more convenient thanusing the ioctl.Signed-off-by: Ezequiel Garcia Tested-by: Pekon Gupta Signed-off-by: Brian Norris List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-mtd

edbc4540 - mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEAN

Wed, 25 Apr 2012 19:06:11 +0000

mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEANThe drivers' _read() method, absent an error, returns a non-negative integerindicating the maximum number of bit errors that were corrected in any oneregion comprising an ecc step. MTD returns -EUCLEAN if this is >=bitflip_threshold, 0 otherwise. If bitflip_threshold is zero, the comparison isnot made since these devices lack ECC and always return zero in the non-errorcase (thanks Brian)¹. Note that this is a subtle change to the driverinterface.This and the preceding patches in this set were tested with ubi on top of thenandsim and docg4 devices, running the ubi test io_basic from mtd-utils.¹ http://lists.infradead.org/pipermail/linux-mtd/2012-March/040468.htmlSigned-off-by: Mike Dunn Acked-by: Robert Jarzmik Acked-by: Brian Norris Ivan Djelic Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-mtd

d062d4ed - mtd: bitflip_threshold added to mtd_info and sysfs

Wed, 25 Apr 2012 19:06:08 +0000

mtd: bitflip_threshold added to mtd_info and sysfsAn element 'bitflip_threshold' is added to struct mtd_info, and also exposed asa read/write variable in sysfs. This will be used to determine whether or notmtd_read() returns -EUCLEAN or 0 (absent a hard error). If the driver leaves itas zero, mtd will set it to a default value of ecc_strength.This v2 adds the line that propagates bitflip_threshold from the master to thepartitions - thanks Ivan¹.¹ http://lists.infradead.org/pipermail/linux-mtd/2012-April/040900.htmlSigned-off-by: Mike Dunn Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-mtd
