[PATCH] acpi/nfit: Fix command-supported detection

[PATCH] acpi/nfit: Fix command-supported detection

[Dan Williams]

The _DSM function number validation only happens to succeed when the
generic Linux command number translation corresponds with a
DSM-family-specific function number. This breaks NVDIMM-N
implementations that correctly implement _LSR, _LSW, and _LSI, but do
not happen to publish support for DSM function numbers 4, 5, and 6.

Recall that the support for _LS{I,R,W} family of methods results in the
DIMM being marked as supporting those command numbers at
acpi_nfit_register_dimms() time. The DSM function mask is only used for
ND_CMD_CALL support of non-NVDIMM_FAMILY_INTEL devices.

Fixes: 31eca76ba2fc ("nfit, libnvdimm: limited/whitelisted dimm command...")

Sujith, this is a larger change than what you originally tested, but it
should behave the same. I wanted to consolidate all the code that
handles Linux command number to DIMM _DSM function number translation.

If you have a chance to re-test with this it would be much appreciated.

Thanks for the report!

Re-verified by applying this patch over LTS kernel-4.20.2 with ndctl v62.
namespace creation and modification works fine on Dell NVDIMM-Ns.
Thanks for helping me on this!

Minor nit: Seems like the function could take an nfit_mem parameter instead of an nvdimm.

Function zero?  Is that really the right thing to return here?

I was making it symmetric with payload_dumpable()... but not for any
good reason, will change.

...whoops fumble fingered "send"

Function zero should never be set in nfit_mem->dsm_mask, although the
NVDIMM_FAMILY_MSFT mask violates this assumption. I'll fix that up.

OK, I think I see how it all fits together now, thanks.  It would be
nice if you documented this magical 0 return somehow.
