Alexander Graf	483ba97c0f	KVM: PPC: E500: Make clear_tlb_refs and clear_tlb1_bitmap static ... Host shadow TLB flushing is logic that the guest TLB code should have no insight about. Declare the internal clear_tlb_refs and clear_tlb1_bitmap functions static to the host TLB handling file. Instead of these, we can use the already exported kvmppc_core_flush_tlb(). This gives us a common API across the board to say "please flush any pending host shadow translation". Signed-off-by: Alexander Graf <agraf@suse.de>	2013-01-24 19:23:33 +01:00
Alexander Graf	c015c62b13	KVM: PPC: e500: Implement TLB1-in-TLB0 mapping ... When a host mapping fault happens in a guest TLB1 entry today, we map the translated guest entry into the host's TLB1. This isn't particularly clever when the guest is mapped by normal 4k pages, since these would be a lot better to put into TLB0 instead. This patch adds the required logic to map 4k TLB1 shadow maps into the host's TLB0. Signed-off-by: Alexander Graf <agraf@suse.de>	2013-01-24 19:23:32 +01:00
Alexander Graf	b71c9e2fb7	KVM: PPC: E500: Split host and guest MMU parts ... This patch splits the file e500_tlb.c into e500_mmu.c (guest TLB handling) and e500_mmu_host.c (host TLB handling). The main benefit of this split is readability and maintainability. It's just a lot harder to write dirty code :). Signed-off-by: Alexander Graf <agraf@suse.de>	2013-01-24 19:23:31 +01:00
