Allows to react on hardware changes and to configure the path for the LPAR

from within a running Linux system

•

I/O configuration support (> kernel 2.6.26)

Adds the infrastructure to allow Linux system to change the I/O configuration of

a System z system.

•

Operations are addition, removal and reconfiguration/reassignment of I/O

channels, control units and subchannels.

This support is available only when running Linux on System z in an LPAR.

•

Modularization of qdio and thin interrupts (> kernel 2.6.26)

initialization of the subchannels into seperate, independent units.
