The only thing blocking UMA_MD_SMALL_ALLOC from working on 64-bit booke powerpc was a missing check in pmap_kextract(). Adding DMAP handling into pmap_kextract(), we can now use UMA_MD_SMALL_ALLOC. This should improve performance and stability a bit, since DMAP is always mapped in TLB1, so this relieves pressure on TLB0. MFC after: 3 weeks |
