[Qemu-devel] [PATCH v3 0/3] Support more than 8 MMU modes, speedup PPC by 10%

[Paolo Bonzini]

Patches 1 and 2 enable support from more than 8 MMU modes in TCG (patch
1 is in the targets, patch 2 is in cpu-defs.h).  The TLB size is reduced
proportionally on targets where that is necessary.

Patch 3 uses the new support in the PPC target.

Paolo

v2->v3: - change i386 TCG_TARGET_TLB_DISPLACEMENT_BITS to 31 [rth]
        - tweak comment in patch 2 to account for
          offsetof(CPUArchState, tlb_table[mem_index][0].addend) [rth]


Paolo Bonzini (3):
  tcg: add TCG_TARGET_TLB_DISPLACEMENT_BITS
  softmmu: support up to 12 MMU modes
  target-ppc: use separate indices for various translation modes
