New channel measurements With the chpstat command, you can view channel-path statistics such as utilization and throughput, and query and control the status of the channel-path statistics function chpstat - Display channel-path statistics.
IBM® z17 ™ hardware base kernel support IBM z17 support

IBM z17 has been added throughout.

CPU-MF counters for IBM z17 CPU-Measurement Facility counters for IBM z17 . Using the CPU-measurement facilities
LPAR-level power consumption A command showx LPAR-level power consumption zpwr - Retrieve power readings
Promiscuous Mode Exploitation for new VFs Read a sysfs attribute to check the FID parameter setting. Configuring FIDPARM to support promiscuous mode on a VF
cpacfinfo: tool to provide CPACF information The cpacfinfo command now displays firmware authentication information in form of a hash. cpacfinfo - Obtain CPACF cryptographic information
NETD PCI function support Includes support for direct use of PCI physical functions for NETD type network devices (for example, Network Express).
