| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||
| Description: | ||
| The ubi/ class sub-directory belongs to the UBI subsystem and | ||
| provides general UBI information, per-UBI device information | ||
| and per-UBI volume information. | ||

| What: /sys/class/ubi/version | ||
| Date: July 2006 | ||
| KernelVersion: 2.6.22 | ||
| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||
| Description: | ||
| This file contains version of the latest supported UBI on-media | ||
| format. Currently it is 1, and there is no plan to change this. | ||
| However, if in the future UBI needs on-flash format changes | ||
| which cannot be done in a compatible manner, a new format | ||
| version will be added. So this is a mechanism for possible | ||
| future backward-compatible (but forward-incompatible) | ||
| improvements. | ||

| Description: | ||
| The /sys/class/ubi/ubiX/ubiX_0/, /sys/class/ubi/ubiX/ubiX_1/, | ||

| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||
| Description: | ||
| Volume alignment - the value the logical eraseblock size of | ||
| this volume has to be aligned on. For example, 2048 means that | ||
| logical eraseblock size is multiple of 2048. In other words, | ||
| volume logical eraseblock size is UBI device logical eraseblock | ||
| size aligned to the alignment value. | ||

| if it is corrupted (e.g., due to an interrupted volume update). | ||
|
|
||
| What: /sys/class/ubi/ubiX/ubiX_Y/data_bytes | ||
| Date: July 2006 | ||
| KernelVersion: 2.6.22 | ||
| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||
| Description: | ||
| The amount of data this volume contains. This value makes sense | ||
| only for static volumes, and for dynamic volume it equivalent | ||
| to the total volume size in bytes. | ||
|
|
||
| What: /sys/class/ubi/ubiX/ubiX_Y/dev | ||
| Date: July 2006 | ||
| KernelVersion: 2.6.22 | ||
| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||
| Description: | ||
| Major and minor numbers of the character device corresponding | ||
| to this UBI volume (in <major>:<minor> format). | ||

| Date: July 2006 | ||
| KernelVersion: 2.6.22 | ||
| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||

| Count of physical eraseblock reserved for this volume. | ||
| Equivalent to the volume size in logical eraseblocks. | ||

| Date: July 2006 | ||
| KernelVersion: 2.6.22 | ||
| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||

||
| What: /sys/class/ubi/ubiX/ubiX_Y/upd_marker | ||
| Date: July 2006 | ||
| KernelVersion: 2.6.22 | ||
| Contact: Artem Bityutskiy <dedekind@infradead.org> | ||
| Description: | ||
| Contains ASCII "0\n" if the update marker is not set for this | ||
| volume, and "1\n" if it is set. The update marker is set when | ||
| volume update starts, and cleaned when it ends. So the presence | ||
| of the update marker indicates that the volume is being updated | ||
| at the moment of the update was interrupted. The later may be | ||
| checked using the "corrupted" sysfs file. | ||
|
|
||
| What: /sys/class/ubi/ubiX/ubiX_Y/usable_eb_size | ||

| Description: | ||
| Logical eraseblock size of this volume. Equivalent to logical | ||
| eraseblock size of the device aligned on the volume alignment | ||
| value. |

| What: /sys/bus/pci/devices/.../vpd | ||
| Date: February 2008 | ||
| Contact: Ben Hutchings <bhutchings@solarflare.com> | ||
| Description: | ||
| A file named vpd in a device directory will be a | ||
| binary file containing the Vital Product Data for the | ||
| device. It should follow the VPD format defined in | ||
| PCI Specification 2.1 or 2.2, but users should consider | ||
| that some devices may have malformatted data. If the | ||
| underlying VPD has a writable section then the | ||
| corresponding section of this file will be writable. |
