This is the follow up of:
[PATCH-for-4.2 v1 0/9] s390x: MMU changes and extensions
Without the general MMU rework. It's based on:
[PATCH v2 0/7] s390x/mmu: DAT translation rewrite
This series adds adds EDAT2 MMU support, and implements/indicates related
facilities (ESOP-1, ESOP-2, IEP, ...) for TCG. The QEMU CPU model is
updated.
IEP under QEMU TCG seems to work just fine, when eabling it via the "max"
CPU model - via kvm unit tests:
t460s: ~/git/kvm-unit-tests master $ ./s390x-run s390x/iep.elf -cpu max
[...]
PASS: iep: iep protection: Program interrupt: expected(4) == received(4)
SUMMARY: 1 tests
EXIT: STATUS=1
