If this parameter is not specified, device\n+will be probed by net/nfp driver and will used as a VF net device.\n+\n+This PMD uses (common/nfp) code to access the device firmware.\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+- ``class`` [net|vdpa] (default **net**)\n+\n+ Choose the mode of operation of nfp device.\n+ **net** device will work as network device and will be probed by net/nfp driver.\n+ **vdpa** device will work as vdpa device and will be probed by vdpa/nfp driver.\n+ If this parameter is not specified then nfp device will operate as network device.\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+NFP vDPA PMD provides the following log types available for control:\n+\n+- ``pmd.vdpa.nfp.vdpa`` (default level is **notice**)\n+\n+ Affects driver-wide messages unrelated to any particular devices.\n+\n+- ``pmd.vdpa.nfp.core`` (default level is **notice**)\n+\n+ Affects the core logic of this PMD.\ndiff --git a/drivers/vdpa/meson.build b/drivers/vdpa/meson.build\nindex 77412c7d09..896e8e0304 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+ 'nfp',\n 'sfc',\n ]\n std_deps = ['bus_pci', 'kvargs']\ndiff --git a/drivers/vdpa/nfp/meson.build b/drivers/vdpa/nfp/meson.build\nnew file mode 100644\nindex 0000000000..5eff240055\n--- /dev/null\n+++ b/drivers/vdpa/nfp/meson.build\n@@ -0,0 +1,13 @@\n+# SPDX-License-Identifier: BSD-3-Clause\n+# Copyright (c) 2023 Corigine, Inc.\n+\n+if not is_linux or not dpdk_conf.get('RTE_ARCH_64')\n+ build = false\n+ reason = 'only supported on 64-bit Linux'\n+endif\n+\n+sources = files(\n+ 'nfp_vdpa_log.c',\n+)\n+\n+deps += ['vhost']\ndiff --git a/drivers/vdpa/nfp/nfp_vdpa_log.c b/drivers/vdpa/nfp/nfp_vdpa_log.c\nnew file mode 100644\nindex 0000000000..f5ada20713\n--- /dev/null\n+++ b/drivers/vdpa/nfp/nfp_vdpa_log.c\n@@ -0,0 +1,9 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright (c) 2023 Corigine, Inc.\n+ * All rights reserved.\n+ */\n+\n+#include \"nfp_vdpa_log.h\"\n+\n+RTE_LOG_REGISTER_SUFFIX(nfp_logtype_core, core, NOTICE);\n+RTE_LOG_REGISTER_SUFFIX(nfp_logtype_vdpa, vdpa, NOTICE);\ndiff --git a/drivers/vdpa/nfp/nfp_vdpa_log.h b/drivers/vdpa/nfp/nfp_vdpa_log.h\nnew file mode 100644\nindex 0000000000..cf342329b1\n--- /dev/null\n+++ b/drivers/vdpa/nfp/nfp_vdpa_log.h\n@@ -0,0 +1,21 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright (c) 2023 Corigine, Inc.\n+ * All rights reserved.\n+ */\n+\n+#ifndef __NFP_VDPA_LOG_H__\n+#define __NFP_VDPA_LOG_H__\n+\n+#include <rte_log.h>\n+\n+extern int nfp_logtype_vdpa;\n+#define DRV_VDPA_LOG(level, fmt, args...) \\\n+\trte_log(RTE_LOG_ ## level, nfp_logtype_vdpa, \\\n+\t\t\"NFP_VDPA: %s(): \" fmt \"\\n\", __func__, ## args)\n+\n+extern int nfp_logtype_core;\n+#define DRV_CORE_LOG(level, fmt, args...) \\\n+\trte_log(RTE_LOG_ ## level, nfp_logtype_core, \\\n+\t\t\"NFP_CORE: %s(): \" fmt \"\\n\", __func__, ## args)\n+\n+#endif /* __NFP_VDPA_LOG_H__ */\n", "prefixes": [ "v4", "18/24" ] }
