IRQ Shared Memory Demo

This README captures information that is shared between the host and remote machine configurations for the IRQ shared memory demo.

Shared Memory Layout

Both sides of the demo operate on the same shared-memory window. Offsets below reflect the AMD reference design; adjust the base address to match the target platform.
