If this parameter is not specified, device\n+will be probed by net/sfc driver and will used as a net device.\n+\n+This PMD uses libefx (common/sfc_efx) code to access the device firmware.\n+\n+\n+Supported NICs\n+--------------\n+\n+- Xilinx SN1022 SmartNICs\n+\n+\n+Features\n+--------\n+\n+Features of the Xilinx vDPA driver are:\n+\n+- Compatibility with virtio 0.95 and 1.0\n+\n+\n+Non-supported Features\n+----------------------\n+\n+- Control Queue\n+- Multi queue\n+- Live Migration\n+\n+\n+Prerequisites\n+-------------\n+\n+Requires firmware version: v1.0.7.0 or higher\n+\n+Visit `Xilinx Support Downloads <https://www.xilinx.com/support.html>`_\n+to get Xilinx Utilities with the latest firmware.\n+Follow instructions from Alveo SN1000 SmartNICs User Guide to\n+update firmware and configure the adapter.\n+\n+\n+Per-Device Parameters\n+~~~~~~~~~~~~~~~~~~~~~\n+\n+The following per-device parameters can be passed via EAL PCI device\n+allowlist option like \"-a 02:00.0,arg1=value1,...\".\n+\n+Case-insensitive 1/y/yes/on or 0/n/no/off may be used to specify\n+boolean parameters value.\n+\n+- ``class`` [net|vdpa] (default **net**)\n+\n+ Choose the mode of operation of ef100 device.\n+ **net** device will work as network device and will be probed by net/sfc driver.\n+ **vdpa** device will work as vdpa device and will be probed by vdpa/sfc driver.\n+ If this parameter is not specified then ef100 device will operate as network device.\n+\n+\n+Dynamic Logging Parameters\n+~~~~~~~~~~~~~~~~~~~~~~~~~~\n+\n+One may leverage EAL option \"--log-level\" to change default levels\n+for the log types supported by the driver. The option is used with\n+an argument typically consisting of two parts separated by a colon.\n+\n+Level value is the last part which takes a symbolic name (or integer).\n+Log type is the former part which may shell match syntax.\n+Depending on the choice of the expression, the given log level may\n+be used either for some specific log type or for a subset of types.\n+\n+SFC vDPA PMD provides the following log types available for control:\n+\n+- ``pmd.vdpa.sfc.driver`` (default level is **notice**)\n+\n+ Affects driver-wide messages unrelated to any particular devices.\n+\n+- ``pmd.vdpa.sfc.main`` (default level is **notice**)\n+\n+ Matches a subset of per-port log types registered during runtime.\n+ A full name for a particular type may be obtained by appending a\n+ dot and a PCI device identifier (``XXXX:XX:XX.X``) to the prefix.\ndiff --git a/drivers/vdpa/meson.build b/drivers/vdpa/meson.build\nindex f765fe3..77412c7 100644\n--- a/drivers/vdpa/meson.build\n+++ b/drivers/vdpa/meson.build\n@@ -8,6 +8,7 @@ endif\n drivers = [\n 'ifc',\n 'mlx5',\n+ 'sfc',\n ]\n std_deps = ['bus_pci', 'kvargs']\n std_deps += ['vhost']\ndiff --git a/drivers/vdpa/sfc/meson.build b/drivers/vdpa/sfc/meson.build\nnew file mode 100644\nindex 0000000..4255d65\n--- /dev/null\n+++ b/drivers/vdpa/sfc/meson.build\n@@ -0,0 +1,22 @@\n+# SPDX-License-Identifier: BSD-3-Clause\n+#\n+# Copyright(c) 2020-2021 Xilinx, Inc.\n+\n+if (arch_subdir != 'x86' or not dpdk_conf.get('RTE_ARCH_64')) and (arch_subdir != 'arm' or not host_machine.cpu_family().startswith('aarch64'))\n+\tbuild = false\n+\treason = 'only supported on x86_64 and aarch64'\n+endif\n+\n+fmt_name = 'sfc_vdpa'\n+extra_flags = []\n+\n+foreach flag: extra_flags\n+\tif cc.has_argument(flag)\n+\t\tcflags += flag\n+\tendif\n+endforeach\n+\n+deps += ['common_sfc_efx', 'bus_pci']\n+sources = files(\n+\t'sfc_vdpa.c',\n+)\ndiff --git a/drivers/vdpa/sfc/sfc_vdpa.c b/drivers/vdpa/sfc/sfc_vdpa.c\nnew file mode 100644\nindex 0000000..f087944\n--- /dev/null\n+++ b/drivers/vdpa/sfc/sfc_vdpa.c\n@@ -0,0 +1,282 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ *\n+ * Copyright(c) 2020-2021 Xilinx, Inc.\n+ */\n+\n+#include <stdbool.h>\n+#include <stdint.h>\n+#include <sys/queue.h>\n+\n+#include <rte_common.h>\n+#include <rte_errno.h>\n+#include <rte_string_fns.h>\n+#include <rte_vfio.h>\n+#include <rte_vhost.h>\n+\n+#include \"efx.h\"\n+#include \"sfc_efx.h\"\n+#include \"sfc_vdpa.h\"\n+\n+TAILQ_HEAD(sfc_vdpa_adapter_list_head, sfc_vdpa_adapter);\n+static struct sfc_vdpa_adapter_list_head sfc_vdpa_adapter_list =\n+\tTAILQ_HEAD_INITIALIZER(sfc_vdpa_adapter_list);\n+\n+static pthread_mutex_t sfc_vdpa_adapter_list_lock = PTHREAD_MUTEX_INITIALIZER;\n+\n+struct sfc_vdpa_adapter *\n+sfc_vdpa_get_adapter_by_dev(struct rte_pci_device *pdev)\n+{\n+\tbool found = false;\n+\tstruct sfc_vdpa_adapter *sva;\n+\n+\tpthread_mutex_lock(&sfc_vdpa_adapter_list_lock);\n+\n+\tTAILQ_FOREACH(sva, &sfc_vdpa_adapter_list, next) {\n+\t\tif (pdev == sva->pdev) {\n+\t\t\tfound = true;\n+\t\t\tbreak;\n+\t\t}\n+\t}\n+\n+\tpthread_mutex_unlock(&sfc_vdpa_adapter_list_lock);\n+\n+\treturn found ?
