From 4898d3f49b5b156c33f0ae0f49ede417ab86195e Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Wed, 22 Mar 2017 15:21:51 +1100 Subject: [PATCH] KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_VFIO capability number This adds a capability number for in-kernel support for VFIO on SPAPR platform. The capability will tell the user space whether in-kernel handlers of H_PUT_TCE can handle VFIO-targeted requests or not. If not, the user space must not attempt allocating a TCE table in the host kernel via the KVM_CREATE_SPAPR_TCE KVM ioctl because in that case TCE requests will not be passed to the user space which is desired action in the situation like that.
