What's new for SUSE Linux Enterprise Server 15 SP5
This update contains the following changes as compared to SUSE Linux® Enterprise Server 15 SP4.
- New information
-
- The chzdev and lszdev commands now support site-specific definition of devices, see Site-specific Linux instantiation.
- NVMe disks are now supported as a stand-alone dump devices, see Managing NVMe devices.
- The DASD device driver can now handle devices with copy-pair relations, see Working with DASDs in a copy-pair relation.
- For SCSI boot devices, new sections describe how use the HMC Web Services API to boot Linux in LPAR mode and in a DPM partition, and how to boot Linux in a DPM partition using the HMC GUI, see Using the HMC Web Services API to boot in LPAR mode and Booting Linux in a DPM partition.
- Automatic recovery and an enhanced zpcictl command help you to manage malfunctioning PCI devices, see Recovering a PCIe device.
- Enhancements for KVM on IBM Z® include persistent configurations for VFIO mediated devices and sharing of host file system branches with KVM guests, see KVM virtual server integration.
- A z/Architecture® implementation of the ChaCha20 stream cipher that uses the IBM Z vector extensions is now available, see Hardware-accelerated in-kernel cryptography.
- Hotplug support is now available for AP queues in KVM guests, see Setting up cryptographic adapter resources for VFIO pass-through.
- You can now use the CPU Processor Activity Instrumentation Facility that was introduced with IBM z16® and IBM LinuxONE 4 to obtain counter data for specific cryptographic and analytic instructions, see Using the CPU Processor Activity Instrumentation Facility.
- The information for cryptographic adapters in sysfs and the lszcrypt command have been extended to fully support CEX8S adapters, see Displaying information about cryptographic devices and lszcrypt - Display cryptographic devices.
- As of IBM z16 and IBM LinuxONE 4, secure guests can now provide evidence that they are running on trusted hardware in IBM Secure Execution mode, see Linux as an IBM Secure Execution host or guest.
- As of IBM z16, the cpacfstats command can handle counters for Processor Activity Instrumentation (PAI), see cpacfstats - Monitor CPACF cryptographic activity.
- Changed Information
-
- Control domains for customized cryptographic device nodes must now be explicitly configured, see Creating customized device nodes.
- With version 2.20.0, the s390-tools package depends on version 3 of the FUSE library. As a consequence, you can no longer use the nonempty option for the cmsfs-fuse, hmcdrvfs and zdsfs commands.
- Deprecated Information
-
- The snipl command and the sncap command have become obsolete. Information about these commands has been removed.
