|
|
Direct Access (DAX) can be used on memory-backed block devices.
|
|
If the block device supports DAX and the filesystem supports DAX,
|
|
then you can avoid using the pagecache to buffer I/Os. Turning
|
|
on this option will compile in support for DAX.
|
|
|
|
For a DAX device to support file system access it needs to have
|
|
struct pages. For the nfit based NVDIMMs this can be enabled
|
|
using the ndctl utility:
|
|
|
|
# ndctl create-namespace --force --reconfig=namespace0.0 \
|
|
--mode=fsdax --map=mem
|
|
|
|
See the 'create-namespace' man page for details on the overhead of
|
|
--map=mem:
|
|
https://docs.pmem.io/ndctl-user-guide/ndctl-man-pages/ndctl-create-namespace
|
|
|
|
For ndctl to work CONFIG_DEV_DAX needs to be enabled as well. For most
|
|
file systems DAX support needs to be manually enabled globally or
|
|
per-inode using a mount option as well. See the file documentation in
|
|
Documentation/filesystems/dax.rst for details.
|
|
|
|
If you do not have a block device that is capable of using this,
|
|
or if unsure, say N. Saying Y will increase the size of the kernel
|
|
by about 5kB.

Tmpfs is a file system which keeps all files in virtual memory.
|
|
|
|
Everything in tmpfs is temporary in the sense that no files will be
|
|
created on your hard drive. The files live in memory and swap
|
|
space. If you unmount a tmpfs instance, everything stored therein is
|
|
lost.

POSIX ACL support under /dev for certain features to work properly.

help
|
|
tmpfs has historically used only inode numbers as wide as an unsigned
|
|
int. In some cases this can cause wraparound, potentially resulting
|
|
in multiple files with the same inode number on a single device. This
|
|
option makes tmpfs use the full width of ino_t by default, without
|
|
needing to specify the inode64 option when mounting.
|
|
|
|
But if a long-lived tmpfs is to be accessed by 32-bit applications so
|
|
ancient that opening a file larger than 2GiB fails with EINVAL, then
|
|
the INODE64 config option and inode64 mount option risk operations
|
|
failing with EOVERFLOW once 33-bit inode numbers are reached.
|
|
|
|
To override this configured default, use the inode32 or inode64
|
|
option when mounting.

If unsure, say N.
