From 1cb9cf726efeb77e05ee4f27f32700c46ecb1b8a Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Mon, 20 Jul 2015 15:04:48 +0200 Subject: [PATCH] KVM: s390: improve debug feature usage We do not use the exception logger, so the 2nd area is unused. Just have one area that is bigger (32 pages). At the same time we can limit the debug feature size to 7 longs, as the largest user has 3 parameters + string + boiler plate (vCPU, PSW mask, PSW addr) Signed-off-by: Christian Borntraeger Acked-by: Cornelia Huck --- arch/s390/kvm/kvm-s390.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/s390/kvm/kvm-s390.c b/arch/s390/kvm/kvm-s390.c index b623267d60cc..4c1b5cbea1a6 100644 --- a/arch/s390/kvm/kvm-s390.c +++ b/arch/s390/kvm/kvm-s390.c @@ -1057,7 +1057,7 @@ int kvm_arch_init_vm(struct kvm *kvm, unsigned long type) sprintf(debug_name, "kvm-%u", current->pid); - kvm->arch.dbf = debug_register(debug_name, 8, 2, 8 * sizeof(long)); + kvm->arch.dbf = debug_register(debug_name, 32, 1, 7 * sizeof(long)); if (!kvm->arch.dbf) goto out_err;
