Hi,

I get the following error when running ndctl's make check:

check_smart: HAVE_NDCTL_SMART disabled, skipping
check_smart_threshold: HAVE_NDCTL_SMART disabled, skipping

Looking at nfit_test there are indeed some holders left:
linux-te3r:~/ndctl/test # lsmod | grep nfit_test
nfit_test              24576  9
nfit                   45056  9 nfit_test

nfit_test_iomap        16384  6 dax,nfit,libnvdimm,dax_pmem,nd_pmem,nfit_test
linux-te3r:~/ndctl/test #

This is with 4.7-rc4

The other tests of the suite are all PASS.

Has anyone else seen this problems?

Thanks,
	Johannes

Do you have CONFIG_DEV_DAX_PMEM=m?

This is intentional so that we can do some forensics after a failure.
All "bus provider" modules (i.e. nfit_test, nfit, and nd_e820) are
pinned while any of their regions are active.  Disable all regions to
remove a module:

# ndctl disable-region all
# modprobe -r nfit_test

I also met this error with CONFIG_DEV_DAX_PMEM=m

Can you re-run the test with kernel debugging enabled and piping the
test messages to the kernel buffer.

Add the following to the kernel command line:

    libnvdimm.dyndbg nfit.dyndbg nd_pmem.dyndbg nd_btt.dyndbg
dax_pmem.dyndbg dax.dyndbg

Specify add --enable-test when configuring ndctl and then run:

    ndctl test 2>/dev/kmsg

...and send the log?

Sure, will retest it and send the log later this week.

Here's the log. I did a dmesg -C to clear off all old stuff beforehand.

Thanks for looking into it.

I think there is variability in the alignment of the DMA_CMA start
address from system-to-system which is why the test is passing for me.

The recent changes to the dax unit tests [1] [2] prevent this failure
by moving higher order dax / pfn testing to a memmap=ss!nn
configuration instead of nfit_test.

Specifically I think we are failing because the configuration needs
the allocation to be "2097152" (2MB) aligned, but it randomly ends up
on a 1MB alignment.
