How much energy can I produce per kg of hydrogen using this process?

In the far future the posthuman successors of mankind have disassembled the stars and live on ultra slow and ultra efficient solar system sized computers, Matrioshka Brains. The last enemy of intelligent life is entropy, the harbinger of the universes inevitable heat death. Once there is no energy gradiant left to exploit entropys final order will purge the universe of all life.

For obvious reasons this fate should be delayed as long as possible, so the most efficient use of resources usable for energy generation is imperative. Leaving fission and the harvesting of the hawking radiation and rotational energy of black holes of the table; I'm interested in how much energy can be generated out of one kilogram of hydrogen using the following process.

The hydrogen is fused into helium using the NCO-cycle as efficiently as plausible followed by helium, carbon, neon, oxygen and silicon fusion. The iron produced by this process can't produce netto energy in a fusion process anymore, so it is fed to a black hole to harvest the frictional energy it will produce in the accretion disk. As I understand it this should be the most efficient way to generate energy from matter if I didn't miss anything.
