pseries: Rewrite CAS PVR compatibility logic During boot, PAPR guests negotiate CPU model support with the ibm,client-architecture-support mechanism. The logic to implement this in qemu is very convoluted. This cleans it up to be cleaner, using the new ppc_check_compat() call. The new logic for choosing a compatibility mode is: 1. Usually, use the most recent compatibility mode that is a) supported by the guest b) supported by the CPU and c) no later than the maximum allowed (if specified) 2. If no suitable compatibility mode was found, the guest *does* support this CPU explicitly, and no maximum compatibility mode is specified, then use "raw" mode for the current CPU 3. Otherwise, fail the boot. This differs from the results of the old code: the old code preferred using "raw" mode to a compatibility mode, whereas the new code prefers a compatibility mode if available. Using compatibility mode preferentially means that we're more likely to be able to migrate the guest to a similar but not identical host. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

pseries: Stubs for HPT resizing This introduces stub implementations of the H_RESIZE_HPT_PREPARE and H_RESIZE_HPT_COMMIT hypercalls which we hope to add in a PAPR extension to allow run time resizing of a guest's hash page table. It also adds a new machine property for controlling whether this new facility is available. For now we only allow resizing with TCG, allowing it with KVM will require kernel changes as well. Finally, it adds a new string to the hypertas property in the device tree, advertising to the guest the availability of the HPT resizing hypercalls. This is a tentative suggested value, and would need to be standardized by PAPR before being merged.

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.

spapr: Clean up handling of DR-indicator There are 3 types of "indicator" associated with hotplug in the PAPR spec the "allocation state", "isolation state" and "DR-indicator". The first two are intimately tied to the various state transitions associated with hotplug. The DR-indicator, however, is different and simpler. It's basically just a guest controlled variable which can be used by the guest to flag state or problems associated with a device. The idea is that the hypervisor can use it to present information back on management consoles (on some machines with PowerVM it may even control physical LEDs on the machine case associated with the relevant device). For that reason, there's only ever likely to be a single update implementation so the set_indicator_state method isn't useful. Replace it with a direct function call. While we're there, make some small associated cleanups: * PAPR doesn't use the term "indicator state", just "DR-indicator" and the allocation state and isolation state are also considered "indicators". Rename things to be less confusing * Fold set_indicator_state() and rtas_set_indicator_state() into a single rtas_set_dr_indicator() function.

spapr: Consolidate DRC state variables Each DRC has three fields describing its state: isolation_state, allocation_state and configured. At first this seems like a reasonable representation, since its based directly on the PAPR defined isolation-state and allocation-state indicators. However: * Only a few combinations of the two fields' values are permitted * allocation_state isn't used at all for physical DRCs * The indicators are write only so they don't really have a well defined current value independent of each other This replaces these variables with a single state variable, whose names and numbers are based on the diagram in LoPAPR section 13.4. Along with this we add code to check the current state on various operations and make sure the requested transition is permitted. Strictly speaking, this makes guest visible changes to behaviour (since we probably allowed some transitions we shouldn't have before). However, a hypothetical guest broken by that wasn't PAPR compliant, and probably wouldn't have worked under PowerVM.
