From e44fc8c9dab215ac0e398622a05574cffd5f5184 Mon Sep 17 00:00:00 2001 From: Ekaterina Tumanova Date: Fri, 30 Jan 2015 16:55:56 +0100 Subject: [PATCH] KVM: s390: introduce post handlers for STSI The Store System Information (STSI) instruction currently collects all information it relays to the caller in the kernel. Some information, however, is only available in user space. An example of this is the guest name: The kernel always sets "KVMGuest", but user space knows the actual guest name. This patch introduces a new exit, KVM_EXIT_S390_STSI, guarded by a capability that can be enabled by user space if it wants to be able to insert such data. User space will be provided with the target buffer and the requested STSI function code.
