Today this\n is done unconditionally (from DPDK 17.11 onwards) i.e. irrespective of IOMMU\n feature being enabled on the vhostuser device, iotlb is initialized. This\n breaks the backward compatibility for applications like OVS due to increase\n in the DPDK memory footprint and causes upgrade failures.\n\nThis patch is to do iotlb_init only if IOMMU feature is enabled on device.\n\nSigned-off-by: Nitin Katiyar <nitin.katiyar@ericsson.com>\n---\n lib/librte_vhost/iotlb.c | 7 +++++++\n lib/librte_vhost/vhost_user.c | 7 +++++++\n 2 files changed, 14 insertions(+)", "diff": "diff --git a/lib/librte_vhost/iotlb.c b/lib/librte_vhost/iotlb.c\nindex c11ebca..0d7c820 100644\n--- a/lib/librte_vhost/iotlb.c\n+++ b/lib/librte_vhost/iotlb.c\n@@ -310,6 +310,13 @@ struct vhost_iotlb_entry {\n \tstruct vhost_virtqueue *vq = dev->virtqueue[vq_index];\n \tint socket = 0;\n \n+\tif (dev->features & (1ULL << VIRTIO_F_IOMMU_PLATFORM)) {\n+\t\tRTE_LOG(ERR, VHOST_CONFIG,\n+\t\t\t\"IOMMU feature is not enabled for this dev(%s)\\n\",\n+\t\t\tdev->ifname);\n+\t\treturn -1;\n+\t}\n+\n \tif (vq->iotlb_pool) {\n \t\t/*\n \t\t * The cache has already been initialized,\ndiff --git a/lib/librte_vhost/vhost_user.c b/lib/librte_vhost/vhost_user.c\nindex 26cfebe..ca787f3 100644\n--- a/lib/librte_vhost/vhost_user.c\n+++ b/lib/librte_vhost/vhost_user.c\n@@ -1274,6 +1274,13 @@\n \tuint16_t i;\n \tuint64_t vva, len;\n \n+\tif (dev->features & (1ULL << VIRTIO_F_IOMMU_PLATFORM)) {\n+\t\tRTE_LOG(ERR, VHOST_CONFIG,\n+\t\t\t\"IOMMU feature is not enabled for this dev(%s)\\n\",\n+\t\t\tdev->ifname);\n+\t\treturn -1;\n+\t}\n+\n \tswitch (imsg->type) {\n \tcase VHOST_IOTLB_UPDATE:\n \t\tlen = imsg->size;\n", "prefixes": [] }
