Date: Thu, 26 Sep 2019 12:16:22 +0200	[thread overview]
Message-ID: <20190926101627.23376-1-david@redhat.com> (raw)

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

Changes since "[PATCH-for-4.2 v1 0/9] s390x: MMU changes and extensions":

- "s390x/mmu: Implement Instruction-Execution-Protection Facility"
-- Make sure s390_cpu_get_phys_page_debug() doesn't choke on IEP
- "s390x/cpumodel: Add new TCG features to QEMU cpu model"
-- Add comment "features introduced after the z13"
