From a3ed8dae6e3db479ca275883ba7fe994170b0ae6 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Wed, 18 Mar 2015 13:54:31 +0100 Subject: [PATCH] KVM: s390: enable more features that need no hypervisor changes After some review about what these facilities do, the following facilities will work under KVM and can, therefore, be reported to the guest if the cpu model and the host cpu provide this bit. There are plans underway to make the whole bit thing more readable, but its not yet finished. So here are some last bit changes and we enhance the KVM mask with: 9 The sense-running-status facility is installed in the z/Architecture architectural mode. ---> handled by SIE or KVM 10 The conditional-SSKE facility is installed in the z/Architecture architectural mode. ---> handled by SIE. KVM will retry SIE 13 The IPTE-range facility is installed in the z/Architecture architectural mode. ---> handled by SIE. KVM will retry SIE 36 The enhanced-monitor facility is installed in the z/Architecture architectural mode. ---> handled by SIE 47 The CMPSC-enhancement facility is installed in the z/Architecture architectural mode. ---> handled by SIE 48 The decimal-floating-point zoned-conversion facility is installed in the z/Architecture architectural mode. ---> handled by SIE 49 The execution-hint, load-and-trap, miscellaneous- instruction-extensions and processor-assist ---> handled by SIE 51 The local-TLB-clearing facility is installed in the z/Architecture architectural mode. ---> handled by SIE 52 The interlocked-access facility 2 is installed. ---> handled by SIE 53 The load/store-on-condition facility 2 and load-and- zero-rightmost-byte facility are installed in the z/Architecture architectural mode. ---> handled by SIE 57 The message-security-assist-extension-5 facility is installed in the z/Architecture architectural mode. ---> handled by SIE 66 The reset-reference-bits-multiple facility is installed in the z/Architecture architectural mode. ---> handled by SIE. KVM will retry SIE 80 The decimal-floating-point packed-conversion facility is installed in the z/Architecture architectural mode. ---> handled by SIE Signed-off-by: Christian Borntraeger Tested-by: Michael Mueller Acked-by: Cornelia Huck --- arch/s390/kvm/kvm-s390.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/s390/kvm/kvm-s390.c b/arch/s390/kvm/kvm-s390.c index 9072127bd51b..a1308859887d 100644 --- a/arch/s390/kvm/kvm-s390.c +++ b/arch/s390/kvm/kvm-s390.c @@ -105,8 +105,8 @@ struct kvm_stats_debugfs_item debugfs_entries[] = { /* upper facilities limit for kvm */ unsigned long kvm_s390_fac_list_mask[] = { - 0xff82fffbf4fc2000UL, - 0x005c000000000000UL, + 0xffe6fffbfcfdfc40UL, + 0x205c800000000000UL, }; unsigned long kvm_s390_fac_list_mask_size(void) -- 2.20.1
