Got it.
And now I can see those two commands `nvme show-regs` and
`nvme show-regs -o binary` have different results for the register
range. The binary output covers just 0x50 size, but it shows all the
registers including BP-related things in normal && json format.
Anyway, I'll prepare a patch for nvme-cli to support binary output
format to cover BP things also.
Thanks, for your reply.
