mtd: nandbiterrs: Support for NAND biterrors test on platforms without raw write

2016-07-11T06:40:13+00:00

Support for NAND biterrors test on platforms without raw write

While the default test mode relies on raw write (mtd_write_oob) to introduce
bit errors into a page, the rewrite test mode doesn't need it.

Changed the overwrite test to use normal writes. The default test mode
is unaffected and still requires raw write as before.

mtd: kill the ecclayout->oobavail field

2016-03-08T00:23:09+00:00

ecclayout->oobavail is just redundant with the mtd->oobavail field.
Moreover, it prevents static const definition of ecc layouts since the
NAND framework is calculating this value based on the ecclayout->oobfree
field.

mtd: tests: consolidate kmalloc/memset 0 call to kzalloc

2016-01-06T23:17:42+00:00

This is an API consolidation only. The use of kmalloc + memset to 0
is equivalent to kzalloc.

mtd: tests: Replace timeval with ktime_t

2015-10-26T20:23:47+00:00

Changes the 32-bit time type timeval to the 64-bit time type
ktime_t, since 32-bit systems using struct timeval will break in the
year 2038. Correspondingly change do_gettimeofday() to ktime_get()
since ktime_get returns a ktime_t, but do_gettimeofday returns a
struct timeval.Here, ktime_get() is used instead of ktime_get_real()
since ktime_get() uses monotonic clock.

mtd: mtd_oobtest: Fix the address offset with vary_offset case

2015-08-27T23:30:01+00:00

When vary_offset is set (e.g. test case 3), the offset is not always
zero so memcmpshow() will show the wrong offset in the print message.
To fix this we introduce a new function memcmpshowoffset() which takes
offset as a parameter and displays the right offset and use it in
the case where offset is non zero.

The old memcmpshow() functionality is preserved by converting it into
a macro with offset preset to 0.

mtd: Make MTD tests cancelable

2015-04-06T01:12:53+00:00

I always go nuts when I start an MTD test on a slow device and have to
wait forever until it finishes. From the debug output I already know
what the issue is but I have to wait or reset the board hard. Resetting
is often not an option (remote access, you don't want lose the current
state, etc...).

The solution is easy, check for pending signals at key positions in the
code. Using that one can even stop a test by pressing CTRL-C as
insmod/modprobe have SIGINT pending.

mtd: mtd_oobtest: Fix bitflip_limit usage in test case 3

2015-04-06T01:10:23+00:00

In test case 3, we set vary_offset to write at different
offsets and lengths in the OOB available area. We need to
do the bitflip_limit check while checking for 0xff outside the
OOB offset + length area that we didn't modify during write.
