on MMU 61 depends on ZONE_DEVICE 62 select FS_IOMAP 63 select DAX 64 help 65 Direct Access (DAX) can be used on memory-backed block devices. 66 If the block device supports DAX and the filesystem supports DAX, 67 then you can avoid using the pagecache to buffer I/Os. Turning 68 on this option will compile in support for DAX. 69 70 For a DAX device to support file system access it needs to have 71 struct pages. For the nfit based NVDIMMs this can be enabled 72 using the ndctl utility: 73 74 # ndctl create-namespace --force --reconfig=namespace0.0 --mode=fsdax --map=mem 75 > 76 See the 'create-namespace' man page for details on the overhead of --map=mem: 77 78 https://docs.pmem.io/ndctl-user-guide/ndctl-man-pages/ndctl-create-namespace 79 80 For ndctl to work CONFIG_DEV_DAX needs to be enabled as well. For most 81 file systems DAX support needs to be manually enabled globally or 82 per-inode using a mount option as well. See the file documentation in 83 Documentation/filesystems/dax.rst for details. 84 85 If you do not have a block device that is capable of using this, 86 or if unsure, say N. Saying Y will increase the size of the kernel 87 by about 5kB. 88 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
