From: Bruce Richardson Date: Fri, 5 Jul 2019 09:34:00 +0000 (+0100) Subject: drivers/raw: remove rawdev from directory names X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=473c88f9b391;p=dpdk.git drivers/raw: remove rawdev from directory names The ifpga and skeleton rawdev drivers included "rawdev" in their directory names, which was superfluous given that they were in the drivers/raw directory. Shorten the names via this patch. For meson builds, this will rename the final library .so/.a files produced, but those will be renamed again later via a patch to standardize rawdev names.

This is +enabled by default in builds for x86 platforms, and disabled in other +configurations. + +For builds using ``meson`` and ``ninja``, the driver will be built when the +target platform is x86-based. + +Device Setup +------------- + +The Intel\ |reg| QuickData Technology HW devices will need to be bound to a +user-space IO driver for use. The script ``dpdk-devbind.py`` script +included with DPDK can be used to view the state of the devices and to bind +them to a suitable DPDK-supported kernel driver. When querying the status +of the devices, they will appear under the category of "Misc (rawdev) +devices", i.e. the command ``dpdk-devbind.py --status-dev misc`` can be +used to see the state of those devices alone. + +Device Probing and Initialization +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Once bound to a suitable kernel device driver, the HW devices will be found +as part of the PCI scan done at application initialization time. No vdev +parameters need to be passed to create or initialize the device. + +Once probed successfully, the device will appear as a ``rawdev``, that is a +"raw device type" inside DPDK, and can be accessed using APIs from the +``rte_rawdev`` library. + +Using IOAT Rawdev Devices +-------------------------- + +To use the devices from an application, the rawdev API can be used, along +with definitions taken from the device-specific header file +``rte_ioat_rawdev.h``. This header is needed to get the definition of +structure parameters used by some of the rawdev APIs for IOAT rawdev +devices, as well as providing key functions for using the device for memory +copies. + +Getting Device Information +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Basic information about each rawdev device can be queried using the +``rte_rawdev_info_get()`` API. For most applications, this API will be +needed to verify that the rawdev in question is of the expected type. For +example, the following code snippet can be used to identify an IOAT +rawdev device for use by an application: + +.. code-block:: C + + for (i = 0; i < count && !found; i++) { + struct rte_rawdev_info info = { .dev_private = NULL }; + found = (rte_rawdev_info_get(i, &info) == 0 && + strcmp(info.driver_name, + IOAT_PMD_RAWDEV_NAME_STR) == 0); + } + +When calling the ``rte_rawdev_info_get()`` API for an IOAT rawdev device, +the ``dev_private`` field in the ``rte_rawdev_info`` struct should either +be NULL, or else be set to point to a structure of type +``rte_ioat_rawdev_config``, in which case the size of the configured device +input ring will be returned in that structure. + +Device Configuration +~~~~~~~~~~~~~~~~~~~~~ + +Configuring an IOAT rawdev device is done using the +``rte_rawdev_configure()`` API, which takes the same structure parameters +as the, previously referenced, ``rte_rawdev_info_get()`` API. The main +difference is that, because the parameter is used as input rather than +output, the ``dev_private`` structure element cannot be NULL, and must +point to a valid ``rte_ioat_rawdev_config`` structure, containing the ring +size to be used by the device. The ring size must be a power of two, +between 64 and 4096. + +The following code shows how the device is configured in +``test_ioat_rawdev.c``: + +.. code-block:: C + + #define IOAT_TEST_RINGSIZE 512 + struct rte_ioat_rawdev_config p = { .ring_size = -1 }; + struct rte_rawdev_info info = { .dev_private = &p }; + + /* ... */ + + p.ring_size = IOAT_TEST_RINGSIZE; + if (rte_rawdev_configure(dev_id, &info) != 0) { + printf("Error with rte_rawdev_configure()\n"); + return -1; + } + +Once configured, the device can then be made ready for use by calling the +``rte_rawdev_start()`` API. + +Performing Data Copies +~~~~~~~~~~~~~~~~~~~~~~~ + +To perform data copies using IOAT rawdev devices, the functions +``rte_ioat_enqueue_copy()`` and ``rte_ioat_do_copies()`` should be used. +Once copies have been completed, the completion will be reported back when +the application calls ``rte_ioat_completed_copies()``. + +The ``rte_ioat_enqueue_copy()`` function enqueues a single copy to the +device ring for copying at a later point. The parameters to that function +include the physical addresses of both the source and destination buffers, +as well as two "handles" to be returned to the user when the copy is +completed. These handles can be arbitrary values, but two are provided so +that the library can track handles for both source and destination on +behalf of the user, e.g. virtual addresses for the buffers, or mbuf +pointers if packet data is being copied. + +While the ``rte_ioat_enqueue_copy()`` function enqueues a copy operation on +the device ring, the copy will not actually be performed until after the +application calls the ``rte_ioat_do_copies()`` function. This function +informs the device hardware of the elements enqueued on the ring, and the +device will begin to process them. It is expected that, for efficiency +reasons, a burst of operations will be enqueued to the device via multiple +enqueue calls between calls to the ``rte_ioat_do_copies()`` function. + +The following code from ``test_ioat_rawdev.c`` demonstrates how to enqueue +a burst of copies to the device and start the hardware processing of them: + +.. code-block:: C + + struct rte_mbuf *srcs[32], *dsts[32]; + unsigned int j; + + for (i = 0; i < RTE_DIM(srcs); i++) { + char *src_data; + + srcs[i] = rte_pktmbuf_alloc(pool); + dsts[i] = rte_pktmbuf_alloc(pool); + srcs[i]->data_len = srcs[i]->pkt_len = length; + dsts[i]->data_len = dsts[i]->pkt_len = length; + src_data = rte_pktmbuf_mtod(srcs[i], char *); + + for (j = 0; j < length; j++) + src_data[j] = rand() & 0xFF; + + if (rte_ioat_enqueue_copy(dev_id, + srcs[i]->buf_iova + srcs[i]->data_off, + dsts[i]->buf_iova + dsts[i]->data_off, + length, + (uintptr_t)srcs[i], + (uintptr_t)dsts[i], + 0 /* nofence */) != 1) { + printf("Error with rte_ioat_enqueue_copy for buffer %u\n", + i); + return -1; + } + } + rte_ioat_do_copies(dev_id); + +To retrieve information about completed copies, the API +``rte_ioat_completed_copies()`` should be used. This API will return to the +application a set of completion handles passed in when the relevant copies +were enqueued. + +The following code from ``test_ioat_rawdev.c`` shows the test code +retrieving information about the completed copies and validating the data +is correct before freeing the data buffers using the returned handles: + +.. code-block:: C + + if (rte_ioat_completed_copies(dev_id, 64, (void *)completed_src, + (void *)completed_dst) != RTE_DIM(srcs)) { + printf("Error with rte_ioat_completed_copies\n"); + return -1; + } + for (i = 0; i < RTE_DIM(srcs); i++) { + char *src_data, *dst_data; + + if (completed_src[i] != srcs[i]) { + printf("Error with source pointer %u\n", i); + return -1; + } + if (completed_dst[i] != dsts[i]) { + printf("Error with dest pointer %u\n", i); + return -1; + } + + src_data = rte_pktmbuf_mtod(srcs[i], char *); + dst_data = rte_pktmbuf_mtod(dsts[i], char *); + for (j = 0; j < length; j++) + if (src_data[j] != dst_data[j]) { + printf("Error with copy of packet %u, byte %u\n", + i, j); + return -1; + } + rte_pktmbuf_free(srcs[i]); + rte_pktmbuf_free(dsts[i]); + } + + +Querying Device Statistics +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The statistics from the IOAT rawdev device can be got via the xstats +functions in the ``rte_rawdev`` library, i.e. +``rte_rawdev_xstats_names_get()``, ``rte_rawdev_xstats_get()`` and +``rte_rawdev_xstats_by_name_get``.

The ring size must be a power of two, -between 64 and 4096. - -The following code shows how the device is configured in -``test_ioat_rawdev.c``: - -.. code-block:: C - - #define IOAT_TEST_RINGSIZE 512 - struct rte_ioat_rawdev_config p = { .ring_size = -1 }; - struct rte_rawdev_info info = { .dev_private = &p }; - - /* ... */ - - p.ring_size = IOAT_TEST_RINGSIZE; - if (rte_rawdev_configure(dev_id, &info) != 0) { - printf("Error with rte_rawdev_configure()\n"); - return -1; - } - -Once configured, the device can then be made ready for use by calling the -``rte_rawdev_start()`` API. - -Performing Data Copies -~~~~~~~~~~~~~~~~~~~~~~~ - -To perform data copies using IOAT rawdev devices, the functions -``rte_ioat_enqueue_copy()`` and ``rte_ioat_do_copies()`` should be used. -Once copies have been completed, the completion will be reported back when -the application calls ``rte_ioat_completed_copies()``. - -The ``rte_ioat_enqueue_copy()`` function enqueues a single copy to the -device ring for copying at a later point. The parameters to that function -include the physical addresses of both the source and destination buffers, -as well as two "handles" to be returned to the user when the copy is -completed. These handles can be arbitrary values, but two are provided so -that the library can track handles for both source and destination on -behalf of the user, e.g. virtual addresses for the buffers, or mbuf -pointers if packet data is being copied. - -While the ``rte_ioat_enqueue_copy()`` function enqueues a copy operation on -the device ring, the copy will not actually be performed until after the -application calls the ``rte_ioat_do_copies()`` function. This function -informs the device hardware of the elements enqueued on the ring, and the -device will begin to process them. It is expected that, for efficiency -reasons, a burst of operations will be enqueued to the device via multiple -enqueue calls between calls to the ``rte_ioat_do_copies()`` function. - -The following code from ``test_ioat_rawdev.c`` demonstrates how to enqueue -a burst of copies to the device and start the hardware processing of them: - -.. code-block:: C - - struct rte_mbuf *srcs[32], *dsts[32]; - unsigned int j; - - for (i = 0; i < RTE_DIM(srcs); i++) { - char *src_data; - - srcs[i] = rte_pktmbuf_alloc(pool); - dsts[i] = rte_pktmbuf_alloc(pool); - srcs[i]->data_len = srcs[i]->pkt_len = length; - dsts[i]->data_len = dsts[i]->pkt_len = length; - src_data = rte_pktmbuf_mtod(srcs[i], char *); - - for (j = 0; j < length; j++) - src_data[j] = rand() & 0xFF; - - if (rte_ioat_enqueue_copy(dev_id, - srcs[i]->buf_iova + srcs[i]->data_off, - dsts[i]->buf_iova + dsts[i]->data_off, - length, - (uintptr_t)srcs[i], - (uintptr_t)dsts[i], - 0 /* nofence */) != 1) { - printf("Error with rte_ioat_enqueue_copy for buffer %u\n", - i); - return -1; - } - } - rte_ioat_do_copies(dev_id); - -To retrieve information about completed copies, the API -``rte_ioat_completed_copies()`` should be used. This API will return to the -application a set of completion handles passed in when the relevant copies -were enqueued. - -The following code from ``test_ioat_rawdev.c`` shows the test code -retrieving information about the completed copies and validating the data -is correct before freeing the data buffers using the returned handles: - -.. code-block:: C - - if (rte_ioat_completed_copies(dev_id, 64, (void *)completed_src, - (void *)completed_dst) != RTE_DIM(srcs)) { - printf("Error with rte_ioat_completed_copies\n"); - return -1; - } - for (i = 0; i < RTE_DIM(srcs); i++) { - char *src_data, *dst_data; - - if (completed_src[i] != srcs[i]) { - printf("Error with source pointer %u\n", i); - return -1; - } - if (completed_dst[i] != dsts[i]) { - printf("Error with dest pointer %u\n", i); - return -1; - } - - src_data = rte_pktmbuf_mtod(srcs[i], char *); - dst_data = rte_pktmbuf_mtod(dsts[i], char *); - for (j = 0; j < length; j++) - if (src_data[j] != dst_data[j]) { - printf("Error with copy of packet %u, byte %u\n", - i, j); - return -1; - } - rte_pktmbuf_free(srcs[i]); - rte_pktmbuf_free(dsts[i]); - } - - -Querying Device Statistics -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The statistics from the IOAT rawdev device can be got via the xstats -functions in the ``rte_rawdev`` library, i.e. -``rte_rawdev_xstats_names_get()``, ``rte_rawdev_xstats_get()`` and -``rte_rawdev_xstats_by_name_get``. The statistics returned for each device -instance are: - -* ``failed_enqueues`` -* ``successful_enqueues`` -* ``copies_started`` -* ``copies_completed`` diff --git a/drivers/raw/Makefile b/drivers/raw/Makefile index 879fcca615..0b6d13d038 100644 --- a/drivers/raw/Makefile +++ b/drivers/raw/Makefile @@ -4,12 +4,12 @@ include $(RTE_SDK)/mk/rte.vars.mk # DIRS-$() += -DIRS-$(CONFIG_RTE_LIBRTE_PMD_SKELETON_RAWDEV) += skeleton_rawdev +DIRS-$(CONFIG_RTE_LIBRTE_PMD_SKELETON_RAWDEV) += skeleton ifeq ($(CONFIG_RTE_EAL_VFIO)$(CONFIG_RTE_LIBRTE_FSLMC_BUS),yy) DIRS-$(CONFIG_RTE_LIBRTE_PMD_DPAA2_CMDIF_RAWDEV) += dpaa2_cmdif DIRS-$(CONFIG_RTE_LIBRTE_PMD_DPAA2_QDMA_RAWDEV) += dpaa2_qdma endif -DIRS-$(CONFIG_RTE_LIBRTE_PMD_IFPGA_RAWDEV) += ifpga_rawdev +DIRS-$(CONFIG_RTE_LIBRTE_PMD_IFPGA_RAWDEV) += ifpga DIRS-$(CONFIG_RTE_LIBRTE_PMD_IOAT_RAWDEV) += ioat DIRS-$(CONFIG_RTE_LIBRTE_PMD_NTB_RAWDEV) += ntb DIRS-$(CONFIG_RTE_LIBRTE_PMD_OCTEONTX2_DMA_RAWDEV) += octeontx2_dma diff --git a/drivers/raw/ifpga/Makefile b/drivers/raw/ifpga/Makefile new file mode 100644 index 0000000000..5fa9303d59 --- /dev/null +++ b/drivers/raw/ifpga/Makefile @@ -0,0 +1,37 @@ +# SPDX-License-Identifier: BSD-3-Clause +# Copyright(c) 2018 Intel Corporation + +include $(RTE_SDK)/mk/rte.vars.mk + +# +# library name +# +LIB = librte_pmd_ifpga_rawdev.a + +CFLAGS += -DALLOW_EXPERIMENTAL_API +CFLAGS += -O3 +CFLAGS += $(WERROR_FLAGS) +CFLAGS += -I$(RTE_SDK)/drivers/bus/ifpga +CFLAGS += -I$(RTE_SDK)/drivers/raw/ifpga_rawdev +CFLAGS += -I$(RTE_SDK)/drivers/net/ipn3ke +LDLIBS += -lrte_eal +LDLIBS += -lrte_rawdev +LDLIBS += -lrte_bus_vdev +LDLIBS += -lrte_kvargs +LDLIBS += -lrte_bus_pci +LDLIBS += -lrte_bus_ifpga + +EXPORT_MAP := rte_pmd_ifpga_version.map + +LIBABIVER := 1 + +VPATH += $(SRCDIR)/base + +include $(RTE_SDK)/drivers/raw/ifpga/base/Makefile + +# +# all source are stored in SRCS-y +# +SRCS-$(CONFIG_RTE_LIBRTE_PMD_IFPGA_RAWDEV) += ifpga_rawdev.c + +include $(RTE_SDK)/mk/rte.lib.mk diff --git a/drivers/raw/ifpga/base/Makefile b/drivers/raw/ifpga/base/Makefile new file mode 100644 index 0000000000..c5bbcbd5f8 --- /dev/null +++ b/drivers/raw/ifpga/base/Makefile @@ -0,0 +1,32 @@ +#SPDX-License-Identifier: BSD-3-Clause +#Copyright(c) 2010-2018 Intel Corporation + +ifneq ($(CONFIG_RTE_LIBRTE_EAL),) +OSDEP := osdep_rte +else +OSDEP := osdep_raw +endif + +CFLAGS += -I$(RTE_SDK)/drivers/raw/ifpga_rawdev/base/$(OSDEP) + +SRCS-y += ifpga_api.c +SRCS-y += ifpga_enumerate.c +SRCS-y += ifpga_feature_dev.c +SRCS-y += ifpga_fme.c +SRCS-y += ifpga_fme_iperf.c +SRCS-y += ifpga_fme_dperf.c +SRCS-y += ifpga_fme_error.c +SRCS-y += ifpga_port.c +SRCS-y += ifpga_port_error.c +SRCS-y += opae_hw_api.c +SRCS-y += opae_ifpga_hw_api.c +SRCS-y += opae_debug.c +SRCS-y += ifpga_fme_pr.c +SRCS-y += opae_spi.c +SRCS-y += opae_spi_transaction.c +SRCS-y += opae_intel_max10.c +SRCS-y += opae_i2c.c +SRCS-y += opae_at24_eeprom.c +SRCS-y += opae_eth_group.c + +SRCS-y += $(wildcard $(SRCDIR)/base/$(OSDEP)/*.c) diff --git a/drivers/raw/ifpga/base/README b/drivers/raw/ifpga/base/README new file mode 100644 index 0000000000..6b2b171b01 --- /dev/null +++ b/drivers/raw/ifpga/base/README @@ -0,0 +1,46 @@ +.. + +/* SPDX-License-Identifier: BSD-3-Clause + * Copyright(c) 2010-2018 Intel Corporation + */ + +Intel iFPGA driver +================== + +This directory contains source code of Intel FPGA driver released by +the team which develops Intel FPGA Open Programmable Acceleration Engine (OPAE). +The directory of base/ contains the original source package.
