SPDX-License-Identifier: BSD-3-Clause\n+ Copyright(c) 2021 Marvell International Ltd.\n+\n+Marvell CNXK BPHY Driver\n+==========================================\n+\n+CN10K/CN9K Fusion product families offer an internal BPHY unit which provides\n+set of hardware accelerators for performing baseband related operations. Connectivity\n+to the outside world happens through a block called RFOE which is backed by\n+ethernet I/O block called CGX or RPM (depending on the chip version). RFOE\n+stands for Radio Frequency Over Ethernet and provides support for\n+IEEE 1904.3 (RoE) standard.\n+\n+Features\n+--------\n+\n+The BPHY CGX/RPM implements following features in the rawdev API:\n+\n+- Access to BPHY CGX/RPM via set of predefined messages.\n+\n+Device Setup\n+------------\n+\n+The BPHY CGX/RPM devices will need to be bound to a user-space IO driver for\n+use. The script ``dpdk-devbind.py`` script included with DPDK can be used to\n+view the state of the devices and to bind them to a suitable DPDK-supported\n+kernel driver. When querying the status of the devices, they will appear under\n+the category of \"Misc (rawdev) devices\", i.e. the command\n+``dpdk-devbind.py --status-dev misc`` can be used to see the state of those\n+devices alone.\n+\n+To perform data transfer use standard ``rte_rawdev_enqueue_buffers()`` and\n+``rte_rawdev_dequeue_buffers()`` APIs. Not all messages produce sensible\n+responses hence dequeueing is not always necessary.\n+\n+Self test\n+---------\n+\n+On EAL initialization, BPHY CGX/RPM devices will be probed and populated into\n+the raw devices. The rawdev ID of the device can be obtained using invocation\n+of ``rte_rawdev_get_dev_id(\"NAME:x\")`` from the test application, where:\n+\n+- NAME is the desired subsystem: use \"BPHY_CGX\" for\n+ RFOE module,\n+- x is the device's bus id specified in \"bus:device.func\" (BDF) format.\n+\n+Use this identifier for further rawdev function calls.\n+\n+The driver's selftest rawdev API can be used to verify the BPHY CGX/RPM\n+functionality.\ndiff --git a/doc/guides/rawdevs/index.rst b/doc/guides/rawdevs/index.rst\nindex f64ec4427..7fbae40ea 100644\n--- a/doc/guides/rawdevs/index.rst\n+++ b/doc/guides/rawdevs/index.rst\n@@ -11,6 +11,7 @@ application through rawdev API.\n :maxdepth: 2\n :numbered:\n \n+ cnxk_bphy\n dpaa2_cmdif\n dpaa2_qdma\n ifpga\ndiff --git a/drivers/raw/cnxk_bphy/cnxk_bphy_cgx.c b/drivers/raw/cnxk_bphy/cnxk_bphy_cgx.c\nnew file mode 100644\nindex 000000000..e537888f9\n--- /dev/null\n+++ b/drivers/raw/cnxk_bphy/cnxk_bphy_cgx.c\n@@ -0,0 +1,151 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright(C) 2021 Marvell.\n+ */\n+#include <rte_bus_pci.h>\n+#include <rte_rawdev.h>\n+#include <rte_rawdev_pmd.h>\n+\n+#include <roc_api.h>\n+\n+struct cnxk_bphy_cgx_queue {\n+\tunsigned int lmac;\n+\t/* queue holds up to one response */\n+\tvoid *rsp;\n+};\n+\n+struct cnxk_bphy_cgx {\n+\tstruct roc_bphy_cgx *rcgx;\n+\tstruct cnxk_bphy_cgx_queue queues[MAX_LMACS_PER_CGX];\n+\tunsigned int num_queues;\n+};\n+\n+static void\n+cnxk_bphy_cgx_format_name(char *name, unsigned int len,\n+\t\t\t struct rte_pci_device *pci_dev)\n+{\n+\tsnprintf(name, len, \"BPHY_CGX:%x:%02x.%x\", pci_dev->addr.bus,\n+\t\t pci_dev->addr.devid, pci_dev->addr.function);\n+}\n+\n+static const struct rte_rawdev_ops cnxk_bphy_cgx_rawdev_ops = {\n+};\n+\n+static void\n+cnxk_bphy_cgx_init_queues(struct cnxk_bphy_cgx *cgx)\n+{\n+\tstruct roc_bphy_cgx *rcgx = cgx->rcgx;\n+\tunsigned int i;\n+\n+\tfor (i = 0;
