* mtd: tests: consolidate kmalloc/memset 0 call to kzallocNicholas Mc Guire2016-01-061-2/+1
| | | | | | | | This is an API consolidation only. The use of kmalloc + memset to 0 is equivalent to kzalloc. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
* mtd: tests: Replace timeval with ktime_tShraddha Barke2015-10-262-10/+10
| | | | | | | | | | | | | 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 caseRoger Quadros2015-08-271-6/+12
| | | | | | | | | | | | | | 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 cancelableRichard Weinberger2015-04-0510-24/+120
| | | | | | | | | | | | | | | 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 3Roger Quadros2015-04-051-27/+35
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | The torture test should quit once it actually induces an error in the flash. This step was accidentally removed during refactoring.

* mtd: mtd_oobtest: generate consistent data for verificationAkinobu Mita2014-04-171-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | mtd_oobtest writes OOB, read it back and verify. The verification is not correctly done if oobsize is not multiple of 4. Although the data to be written and the data to be compared are generated by several prandom_byte_state() calls starting with the same seed, these two are generated with the different size and different number of calls. Due to the implementation of prandom_byte_state() if the size on each call is not multiple of 4, the resulting data is not always same. This fixes it by just calling prandom_byte_state() once and using correct range instead of calling it multiple times for each.

The code will actually be copied to every test module, but it is fine for our small test infrastructure.
