From 6a81dd172cd5d03fce593741629cb4c78fff10cb Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 30 Sep 2015 13:42:55 +1000 Subject: spapr_iommu: Rename vfio_accel parameter The vfio_accel parameter used when creating a new TCE table (guest IOMMU context) has a confusing name. What it really means is whether we need the TCE table created to be able to support VFIO devices. VFIO is relevant, because when available we use in-kernel acceleration of the TCE table, but that may not work with VFIO devices because updates to the table are handled in kernel, bypass qemu and so don't hit qemu's infrastructure for keeping the VFIO host IOMMU state in sync with the guest IOMMU state. Rename the parameter to "need_vfio" throughout. This is a cosmetic change, with no impact on the logic.
