DESCRIPTION
-----------
Writes and shows the defined NVMe controller register.

The <device> parameter is mandatory and must be the nvme admin character
device (ex: /dev/nvme0).

OPTIONS
-------
-O <offset>::
--offset=<offset>::
	offset of the requested register

-V <val>::
--value=<val>::
	the value of the register to be set

--mmio32::
-m::
	Access 64-bit registers as 2 32-bit

--intms=<val>::
	INTMS=0xc register offset

--intmc=<val>::
	INTMC=0x10 register offset

--cc=<val>::
	CC=0x14 register offset

--csts=<val>::
	CSTS=0x1c register offset

--nssr=<val>::
	NSSR=0x20 register offset

--aqa=<val>::
	AQA=0x24 register offset

--asq=<val>::
	ASQ=0x28 register offset

--acq=<val>::
	ACQ=0x30 register offset

--bprsel=<val>::
	BPRSEL=0x44 register offset

--bpmbl=<val>::
	BPMBL=0x48 register offset

--cmbmsc=<val>::
	CMBMSC=0x50 register offset

--nssd=<val>::
	NSSD=0x64 register offset

--pmrctl=<val>::
	PMRCTL=0xe04 register offset

--pmrmscl=<val>::
	PMRMSCL=0xe14 register offset

--pmrmscu=<val>::
	PMRMSCU=0xe18 register offset

-o <fmt>::
--output-format=<fmt>::
	Set the reporting format to 'normal', 'json' or 'binary'. Only one
	output format can be used at a time.

-v::
--verbose::
	Increase the information detail in the output.

-t <timeout>::
--timeout=<timeout>::
	Override default timeout value. In milliseconds.
