System resourcesEdit online These device drivers and features help you to manage the resources of your real or virtual hardware. RestrictionsFor prerequisites and restrictions see the IBM Z® architecture specific information in the Red Hat® Enterprise Linux® 8.6 release notes at https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux Managing CPUsYou can control the online status, check the capability, and, for LPAR mode, examine the topology of CPUs.Memory hotplugYou can dynamically increase or decrease the memory for your running Linux instance. Huge-page supportHuge-page support entails support for the Linux hugetlbfs file system.S/390 hypervisor file systemThe S/390® hypervisor file system (hypfs) provides a mechanism to access LPAR and z/VM® hypervisor data. TOD clock synchronizationYour Linux instance might be part of an extended remote copy (XRC) setup that requires synchronization of the Linux time-of-day (TOD) clock with a Coordinated Timing Network (CTN).Identifying the IBM Z hardwareIn installations with several IBM Z mainframes, you might need to identify the particular hardware system on which a Linux instance is running. HMC media device driverYou use the HMC media device driver to access files on removable media at a system that runs the Hardware Management Console (HMC).Data compression with the Integrated Accelerator for zEDCThe Integrated Accelerator for zEDC provides on-chip hardware-acceleration for data compression and decompression.Data compression with GenWQE and zEDC ExpressGeneric Work Queue Engine (GenWQE) supports hardware-accelerated data compression and decompression through zEDC Express, a PCIe-attached Field Programmable Gate Array (FPGA) acceleration adapter.PCI Express supportThe Peripheral Component Interconnect Express (PCIe) device driver supports various PCI devices, including but not limited to devices that implement the SMC network protocol.Parent topic: Device Drivers, Features, and Commands on Red Hat Enterprise Linux 8.6
