After seeing some users have subscription management trouble, more spam than other Linux development lists, and considering some of the benefits of kernel.org hosted lists, nvdimm and persistent memory development is moving to nvdimm@lists.linux.dev. The old list will remain up until v5.14-rc1 and shutdown thereafter.

Description: Device DAX is the device-centric analogue of Filesystem
|
|
DAX (CONFIG_FS_DAX). It allows memory ranges to be
|
|
allocated and mapped without need of an intervening file
|
|
system. Device DAX is strict, precise and predictable.
|
|
Specifically this interface:
|
|
|
|
1. Guarantees fault granularity with respect to a given
|
|
page size (pte, pmd, or pud) set at configuration time.
|
|
|
|
2. Enforces deterministic behavior by being strict about
|
|
what fault scenarios are supported.
|
|
|
|
The /sys/class/dax/ interface enumerates all the
|
|
device-dax instances in the system. The ABI is
|
|
deprecated and will be removed after 2020. It is
|
|
replaced with the DAX bus interface /sys/bus/dax/ where
|
|
device-dax instances can be found under
|
|
/sys/bus/dax/devices/
