[Qemu-devel] [PATCH v1 0/3] target/s390x: implement idte and improve ipte

[David Hildenbrand]

One step into the direction of adding the DAT-enhancement facility.

To improve the TLB flushing, we will have to remember each used table (or
at least a hash!) for each tlb entry, just like real HW does.

idte is pretty much untested, before I can test it with linux (by enabling
DAT-enhancement) we will have to implement cspg. Will look into this next.

David Hildenbrand (3):
  target/s390x: Indicate and check for local tlb clearing
  target/s390x: Improve heuristic for ipte
  target/s390x: Implement idte instruction
