Managing PCI functions on Linux on IBM Z

Make PCI functions of RoCE Express available to your Linux® instance and manage them from Linux.

Hardware environment and settings

Hardware defaults and settings govern the following conditions for RoCE Express PCI functions in your LPAR or DPM partition:
  • Which PCI functions are eligible for your partition.
  • Which of these PCI functions are also eligible for other partitions.
  • Whether unique UIDs for each PCI function are enforced in your partition.
  • The initial configuration state of PCI functions in your partition.

Partitioning hardware resources is beyond the scope of this publication. For more information, see, for example, z/OS® HCD User's Guide, SC34-2669.
