To track the reference and change bit, we have to invalidate TLB entries whenever the storage key is changed by the guest and make sur= e not TLB entry is writable in case the storage key does not indicate a change already. With this series, the kvm-unit-test "skey" now passes. \o/ v2 -> v3: - Reshuffled patches to avoid a temporary uninitialized return value - Minor updates to patch descriptions - "s390x/tcg: Flush the TLB of all CPUs on SSKE and RRBE" -- Updated comments - "s390x/mmu: Factor out storage key handling" -- Reduce indentation v1 -> v2: - "s390x/tcg: Rework MMU selection for instruction fetches" -- Cleanup return value handling - Added RB's Cc: Alex Benn=C3=A9e David Hildenbrand (6): s390x/mmu: Trace the right value if setting/getting the storage key fails s390x/mmu: ASC selection in s390_cpu_get_phys_page_debug() s390x/tcg: Rework MMU selection for instruction fetches s390x/tcg: Flush the TLB of all CPUs on SSKE and RRBE s390x/mmu: Better storage key reference and change bit handling s390x/mmu: Factor out storage key handling target/s390x/cpu.h | 7 ++ target/s390x/helper.c | 5 ++ target/s390x/mem_helper.c | 10 +++ target/s390x/mmu_helper.c | 135 ++++++++++++++++++++++++-------------- 4 files changed, 107 insertions(+), 50 deletions(-) --=20 2.21.0
