The patchset aims at mapping guest TLB1 to host TLB0. And it includes: [PATCH 1/2] kvm/e500v2: Remove shadow tlb [PATCH 2/2] kvm/e500v2: mapping guest TLB1 to host TLB0 The reason we need patch 1 is because patch 1 make things simple and flexible. Only applying patch 1 aslo make kvm work.
I've always thought the best long-term "optimization" on these cores is to share in the host PID allocation (i.e. __init_new_context()). This way, the TID in guest mappings would not overlap the TID in host mappings, and guest mappings could be demand-faulted rather than swapped wholesale. To do that, you would need to track the host PID in KVM data structures, I guess in the tlbe_ref structure.
