UBI: switch debugging tests knobs to debugfs

2011-06-01T08:23:12+00:00

Kill the UBI 'debug_tsts' module parameter and switch to debugfs. Create
per-test mode files there. E.g., to enable bit-flips emulation you may just do:

echo 1 > /sys/kernel/debug/ubi/ubi0/tst_emulate_bitflips

UBI: use debugfs for the extra checks knobs

2011-06-01T08:21:47+00:00

This patch introduces debugfs support to UBI. All the UBI stuff is kept in the
"ubi" debugfs directory, which contains per-UBI device "ubi/ubiX"
sub-directories, containing debugging files. This file also creates
"ubi/ubiX/chk_gen" and "ubi/ubiX/chk_io" knobs for switching general and I/O
extra checks on and off. And it removes the 'debug_chks' UBI module parameters.

UBI: switch to dynamic printks

2011-05-20T05:30:34+00:00

Remove custom dynamic prints and the module parameter to toggle them and use
the generic kernel dynamic printk infrastructure.

UBI: fix minor stylistic issues

2011-04-14T08:34:41+00:00

Fix checkpatch.pl errors and warnings:

* space before tab
* line over 80 characters
* include linux/ioctl.h instead of asm/ioctl.h

UBI: make tests modes dynamic

2011-03-16T11:50:17+00:00

Similarly to the debugging checks and message, make the test modes
be dynamically selected via the "debug_tsts" module parameter or
via the "/sys/module/ubi/parameters/debug_tsts" sysfs file. This
is consistent with UBIFS as well.

And now, since all the Kconfig knobs became dynamic, we can remove
the Kconfig.debug file completely.

UBI: make self-checks dynamic

2011-03-16T11:50:16+00:00

This patch adds a possibility to dynamically switch UBI self-checks
on and off, instead of toggling them compile-time from the configuration
menu. This is much more flexible, and consistent with UBIFS, and this
also simplifies UBI Kconfig menu and the code.

This patch introduces two levels of self-checks - general, which
includes all self-checks which are relatively fast, and I/O, which
includes write-verify checks and erase-verify checks, which are
relatively slow and involve flash I/O.

UBI: make debugging messages dynamic

2011-03-16T11:50:16+00:00

This patch adds a possibility to dynamically select UBI debugging
messages, instead of selecting them compile-time from the configuration
menu. This is much more flexible, and consistent with UBIFS, and this
also simplifies UBI Kconfig menu and the code.

UBI: introduce flash dump helper

2009-08-14T17:02:20+00:00

Useful for debugging problems, compiled in only if UBI debugging
is enabled. This patch also makes the UBI writing function dump
the flash if it fails to write.

UBI: add image sequence number to EC header

2009-07-05T15:47:07+00:00

An image sequence number is added to the UBI erase-counter header
to be able determine if the root file system contains a mixture
of old and new images (because the flashing failed to complete).

A change to nolo is also needed for this to take effect.
