2012-06-24pseries: Correctly create ibm,segment-page-sizes propertyBenjamin Herrenschmidt1-0/+43
The core tcg/kvm code for ppc64 now has at least the outline capability to support pagesizes beyond the standard 4k and 16MB. The CPUState is initialized with information advertising the available pagesizes and their correct encodings, and under the right KVM setup this will be populated with page sizes beyond the standard. Obviously guests can't use the extra page sizes unless they know they're present. For the pseries machine, at least, there is a defined method for conveying exactly this information, the "ibm-segment-page-sizes" property in the guest device tree. This patch generates this property using the supported page size information that's already in the CPUState.

2012-06-24ppc64: Rudimentary Support for extra page sizes on server CPUsBenjamin Herrenschmidt5-0/+272
More recent Power server chips (i.e. based on the 64 bit hash MMU) support more than just the traditional 4k and 16M page sizes. This can get quite complicated, because which page sizes are supported, which combinations are supported within an MMU segment and how these page sizes are encoded both in the SLB entry and the hash PTE can vary depending on the CPU model (they are not specified by the architecture). In addition the firmware or hypervisor may not permit use of certain page sizes, for various reasons. Whether various page sizes are supported on KVM, for example, depends on whether the PR or HV variant of KVM is in use, and on the page size of the memory backing the guest's RAM. This patch adds information to the CPUState and cpu defs to describe the supported page sizes and encodings. Since TCG does not yet support any extended page sizes, we just set this to NULL in the static CPU definitions, expanding this to the default 4k and 16M page sizes when we initialize the cpu state. When using KVM, however, we instead determine available page sizes using the new KVM_PPC_GET_SMMU_INFO call. For old kernels without that call, we use some defaults, with some guesswork which should do the right thing for existing HV and PR implementations. The fallback might not be correct for future versions, but that's ok, because they'll have KVM_PPC_GET_SMMU_INFO.

2012-06-24booke_206_tlbwe: Discard invalid bits in MAS2Fabien Chouteau1-2/+15
The size of EPN field in MAS2 depends on page size. This patch adds a mask to discard invalid bits in EPN field. Definition of EPN field from e500v2 RM: EPN Effective page number: Depending on page size, only the bits associated with a page boundary are valid. Bits that represent offsets within a page are ignored and should be cleared. There is a similar (but more complicated) definition in PowerISA V2.06.

2012-06-24PPC: mpc8544ds: Span initial TLB entry over as much RAM as we needAlexander Graf1-14/+27
The initial TLB entry is supposed to help us run the guest -kernel payload. This means the guest needs to be able to access its own memory, the initrd memory and the device tree. So far we only statically reserved a TLB entry from [0;256M[. This patch fixes it to span from [0;dt_end[, allowing the guest payload to access everything initially.

2012-06-22vga: make vram size configurableGerd Hoffmann8-14/+50
Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable for standard vga and vmware vga. cirrus and qxl are left with a fixed size (and private VGA_RAM_SIZE #define) for now. qxl needs some non-trivial adjustments in the mode list handling deal with a runtime-configurable size, which calls for a separate qxl patch. cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess it would make sense to use these sizes. That change would break migration though, so I left it fixed at 8 MB size. Making it configurabls is pretty pointless for cirrus as we have to match real hardware.
