CONFIG_DEV_DAX_CXL: CXL DAX: direct access to CXL RAM regions

General informations

The Linux kernel configuration item CONFIG_DEV_DAX_CXL:

Help text

CXL RAM regions are either mapped by platform-firmware and published in the initial system-memory map as "System RAM", mapped by platform-firmware as "Soft Reserved", or dynamically provisioned after boot by the CXL driver. In the latter two cases a device-dax instance is created to access that unmapped-by-default address range. Per usual it can remain as dedicated access via a device interface, or converted to "System RAM" via the dax_kmem facility.
