Help text

Enable CXL RAW command interface.

The CXL driver ioctl interface may assign a kernel ioctl command number for each specification defined opcode. At any given point in time the number of opcodes that the specification defines and a device may implement may exceed the kernel's set of associated ioctl function numbers. The mismatch is either by omission, specification is too new, or by design. When prototyping new hardware, or developing / debugging the driver it is useful to be able to submit any possible command to the hardware, even commands that may crash the kernel due to their potential impact to memory currently in use by the kernel.

If developing CXL hardware or the driver say Y, otherwise say N.
