This series adds support for a PPC64 platform, SPAPR, on top of the previous more general PPC64 CPU support. This platform is paravirtualised, with most of the MMU hypercalls being dealt with in the kernel. Userland needs to describe the environment to the machine with a device tree, cope with some hypercalls (and RTAS calls) for hvconsole, PCI config and IRQs, and emulate the interrupt controller (XICS) and PCI Host Bridge of the SPAPR-esque machine. With this series, normal pSeries kernels boot fine (including RH kernels that include virtio support out of the box). There is no support for PPC32 or 'bare metal' PPC64 guests as yet. Processor state is set up as a guest kernel would expect (both primary and secondaries), and SMP is fully supported. The kernels are loaded as flat binaries and booted directly. The intention is to later support loading firmware such as SLOF. Some of the code within is borrowed/based upon code in QEMU, particularly the XICS emulation, device tree construction and PCI setup. -- Changes since V3: - Gained another patch to provide PPC KVM-PR support (widens userbase :p ) This allocates a page table, sets up a few more regs etc. Also, removes restriction that mandates use of hugepages. Requires KVM-PR to implement H_BULK_REMOVE (separate patch) - Cleaned up FDT generation to detect host CPU & generate based on its properties; now supports PPC970 as well as POWER7 - Removed redefinition of hypercall #defines, using <asm/hvcall.h> instead - More sensible MMIO layering; CPU passes MMIO to PHB, PHB then decides which PCI window is accessed. - Die if kernel-handled hypercalls ever get to userland - Build in libfdt as sugggested -- it's small and present in our sourcetree, and removes external dependency on 64bit libfdt (which isn't in some distros). - Spit & polish Thanks to David & Alex for the PPC-related reviews!
