Semihalf is happy to announce that &os; is running on an IBM + Power8 processor. This project is a continuation of work done + by Nathan Whitehorn, who provided a basic support for a + PowerNV emulator.

+ +

The IBM Power8 family of CPUs offers superior performance + compared to previous CPUs in the Power series. It provides + complete NUMA support with up to 128 execution threads in + two-socket system (2 sockets, 8 cores per socket, 8 threads + per core). All I/O communication is handled by an integrated + PCIe interface equipped with multiple IOMMU engines.

+ +

The support for Power8 system running &os; in a non-virtualized + environment contains:

+ +
    +
  • A generic driver for the OPAL hypervisor
  • + +
  • kboot loader modifications to allow for a + little-endian to load a big-endian kernel ELF image
  • + +
  • An update to the ELF parser in skiboot, allowing + it to understand the &os; kernel file format
  • + +
  • Basic support for the PowerNV architecture, including + modes of operation, memory-management unit (MMU), and + interrupt controller
  • + +
  • SMP operation with up to 128 CPUs
  • + +
  • PCI host bridge subsystem driver, including IOMMU mapping + for external busses
  • + +
  • PCIe host controller driver
  • + +
  • USB-3.0 XHCI driver
  • + +
  • Reworked several drivers to be big-endian compatible
  • + +
  • Chelsio cxgbe(4) 10/25G network adapter
  • + +
  • NVMe SSD driver
  • +
+ +

All work is available in the linked GitHub repository. The + process of getting this work into the official repository has + already started and eventually, all commits will be integrated + into &os;-12 CURRENT.
