# IBM pSeries (sPAPR)
spapr: Capabilities infrastructure Because PAPR is a paravirtual environment access to certain CPU (or other) facilities can be blocked by the hypervisor. PAPR provides ways to advertise in the device tree whether or not those features are available to the guest. In some places we automatically determine whether to make a feature available based on whether our host can support it, in most cases this is based on limitations in the available KVM implementation. Although we correctly advertise this to the guest, it means that host factors might make changes to the guest visible environment which is bad: as well as generaly reducing reproducibility, it means that a migration between different host environments can easily go bad. We've mostly gotten away with it because the environments considered mature enough to be well supported (basically, KVM on POWER8) have had consistent feature availability. But, it's still not right and some limitations on POWER9 is going to make it more of an issue in future. This introduces an infrastructure for defining "sPAPR capabilities". These are set by default based on the machine version, masked by the capabilities of the chosen cpu, but can be overriden with machine properties. The intention is at reset time we verify that the requested capabilities can be supported on the host (considering TCG, KVM and/or host cpu limitations). If not we simply fail, rather than silently modifying the advertised featureset to the guest. This does mean that certain configurations that "worked" may now fail, but such configurations were already more subtly broken.

spapr_ovec: initial implementation of option vector helpers PAPR guests advertise their capabilities to the platform by passing an ibm,architecture-vec structure via an ibm,client-architecture-support hcall as described by LoPAPR v11, B.6.2.3. during early boot. Using this information, the platform enables the capabilities it supports, then encodes a subset of those enabled capabilities (the 5th option vector of the ibm,architecture-vec structure passed to ibm,client-architecture-support) into the guest device tree via "/chosen/ibm,architecture-vec-5". The logical format of these these option vectors is a bit-vector, where individual bits are addressed/documented based on the byte-wise offset from the beginning of the bit-vector, followed by the bit-wise index starting from the byte-wise offset. Thus the bits of each of these bytes are stored in reverse order. Additionally, the first byte of each option vector is encodes the length of the option vector, so byte offsets begin at 1, and bit offset at 0. This is not very intuitive for the purposes of mapping these bits to a particular documented capability, so this patch introduces a set of abstractions that encapsulate the work of parsing/encoding these options vectors and testing for individual capabilities.

ppc/pnv: add skeleton PowerNV platform The goal is to emulate a PowerNV system at the level of the skiboot firmware, which loads the OS and provides some runtime services. Power Systems have a lower firmware (HostBoot) that does low level system initialization, like DRAM training. This is beyond the scope of what qemu will address in a PowerNV guest. No devices yet, not even an interrupt controller. Just to get started, some RAM to load the skiboot firmware, the kernel and initrd. The device tree is fully created in the machine reset op. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> [clg: - updated for qemu-2.7 - replaced fprintf by error_report - used a common definition of _FDT macro - removed VMStateDescription as migration is not yet supported - added IBM Copyright statements - reworked kernel_filename handling - merged PnvSystem and sPowerNVMachineState - removed PHANDLE_XICP - added ppc_create_page_sizes_prop helper - removed nmi support - removed kvm support - updated powernv machine to version 2.8 - removed chips and cpus, They will be provided in another patches - added a machine reset routine to initialize the device tree (also) - french has a squelette and english a skeleton. - improved commit log. - reworked prototypes parameters - added a check on the ram size (thanks to Michael Ellerman) - fixed chip-id cell - changed MAX_CPUS to 2048 - simplified memory node creation to one node only - removed machine version - rewrote the device tree creation with the fdt "rw" routines - s/sPowerNVMachineState/PnvMachineState/ - etc.] Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

spapr_pci/spapr_pci_vfio: Support Dynamic DMA Windows (DDW) This adds support for Dynamic DMA Windows (DDW) option defined by the SPAPR specification which allows to have additional DMA window(s) The "ddw" property is enabled by default on a PHB but for compatibility the pseries-2.6 machine and older disable it. This also creates a single DMA window for the older machines to maintain backward migration. This implements DDW for PHB with emulated and VFIO devices. The host kernel support is required. The advertised IOMMU page sizes are 4K and 64K; 16M pages are supported but not advertised by default, in order to enable them, the user has to specify "pgsz" property for PHB and enable huge pages for RAM. The existing linux guests try creating one additional huge DMA window with 64K or 16MB pages and map the entire guest RAM to. If succeeded, the guest switches to dma_direct_ops and never calls TCE hypercalls (H_PUT_TCE,...) again. This enables VFIO devices to use the entire RAM and not waste time on map/unmap later. This adds a "dma64_win_addr" property which is a bus address for the 64bit window and by default set to 0x800.0000.0000.0000 as this is what the modern POWER8 hardware uses and this allows having emulated and VFIO devices on the same bus. This adds 4 RTAS handlers: * ibm,query-pe-dma-window * ibm,create-pe-dma-window * ibm,remove-pe-dma-window * ibm,reset-pe-dma-window These are registered from type_init() callback. These RTAS handlers are implemented in a separate file to avoid polluting spapr_iommu.c with PCI. This changes sPAPRPHBState::dma_liobn to an array to allow 2 LIOBNs and updates all references to dma_liobn. However this does not add 64bit LIOBN to the migration stream as in fact even 32bit LIOBN is rather pointless there (as it is a PHB property and the management software can/should pass LIOBNs via CLI) but we keep it for the backward migration support.
