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.Signed-off-by: Artem Bityutskiy
-
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.Signed-off-by: Artem Bityutskiy

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.Signed-off-by: Artem Bityutskiy

This additional little macro is used to print a bit more messages
while scanning the media. However, we have the 'dbg_bld()' macro
for this, so we better us 'dbg_bld()' and kill UBI_IO_DEBUG. This
simplifies the code a tiny bit.Signed-off-by: Artem Bityutskiy
-
This patch kills the 'ubi->dbg_peb_buf' debugging buffer and the
associated mutex, because all users of this buffer are now gone.
We are killing this buffer because we are going to switch to
dynamic debugging control, just like in UBIFS, which means that
CONFIG_MTD_UBI_DEBUG_PARANOID will be removed. In this case we'd
end up always allocating 'ubi->dbg_peb_buf', which is rather large
(128KiB or more), and this would be wasteful. Thus, we are just
killing it.Signed-off-by: Artem Bityutskiy
-
Instead of using pre-allocated 'ubi->dbg_peb_buf' buffer in
'ubi_dbg_check_all_ff()', dynamically allocate it when needed. The
intend is to get rid of the pre-allocated 'ubi->dbg_peb_buf' buffer
completely. And the need for this arises because we want to change
to dynamic debugging control instead of compile-time control, i.e.,
we are going to kill the CONFIG_MTD_UBI_DEBUG_PARANOID Kconfig
option, which would mean that 'ubi->dbg_peb_buf' is always allocated,
which would be wasteful.Thus, we are getting rid of 'ubi->dbg_peb_buf', and this is a
preparation for that.signed-off-by: Artem Bityutskiy

This one liner patch fixes double free that will occur if add_mtd_blktrans_dev
fails. On failure it frees the input argument, but all its users also free it
on error which is natural thing to do. Thus don't free it.All credit for finding that bug belongs to reporters of the bug in the android bugzilla

For some unknown reasons resources needed by amd76xrom driver can be
unavailable. And instead of returning an error, the driver keeps going
and crash the kernel. This patch fixes the problem by making the driver
return -EBUSY if the resources are not available.Commit messages tweaked by Artem.

In the commit 08968041bef437ec363623cd3218c2b083537ada
(mtd: cfi_cmdset_0002: make sector erase command variable)
introdused a field sector_erase_cmd. In the same commit initialisation
of cfi->sector_erase_cmd made in cfi_chip_setup()
(file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem:...
cfi->cfi_mode = CFI_MODE_CFI;
cfi->sector_erase_cmd = CMD(0x30);
...But for the JEDEC chips this initialisation is not carried out,
so the JEDEC chips have sector_erase_cmd == 0.This patch adds the missing initialisation.

In the following commit, we'll need to use the CMD() macro in order to
fix the initialisation of the sector_erase_cmd field. That requires the

Provide the LEB offset information in the UBI device information data
structure. This piece of information is required by UBIFS to find out
what are the LEB offsets which are aligned to the max. write size.If LEB offset not aligned to max. write size, then UBIFS has to take
this into account to write more optimally.Signed-off-by: Artem Bityutskiy

The current multiblock erase verify read timeout 100us is the maximum
for none-error case. If errors happen during multibock erase then
the specification recommends to run multiblock erase verify command
with maximum timeout 10ms (see specs. for KFM4G16Q2A and KFN8G16Q2A).For the most common non-error case we wait 100us in udelay polling
loop. In case of timeout the interrupt mode is used to wait for the
command end.Signed-off-by: Roman Tereshonkov

When the read operation fails, UBI tries to re-read several times in
a hope that one of the subsequent reads may succeed. However, currently
UBI re-reads only if MTD failed to read all data, but does not re-reads
if all the data were read, but with an integrity error (-EBADMSB). This
patch makes UBI to always re-try reading.This should be useful for reading NAND pages with unstable bits -
re-reading may help to get correct data.Signed-off-by: Artem Bityutskiy
