It also introduces Bus registration and\nderegistration functions.\n\nAn example implementation would be like:\n\n .--------------->+-------------------+\n | |rte_pci_bus |\n | | +----------------+|\n | | |rte_bus <------.\n | | | name || |\n | | | scan || |\n | | | match || |\n | | | probe || |\n | | | remove || |\n | | | ... || |\n | | +----------------+| |\n | | pci_driver_list | |\n | .-------------->pci_device_list | |\n | | | ... | |\n | | +-------------------+ |\n | | |\n | +-------------------+ |\n | |rte_pci_device | |\n '----bus | |\n | +----------------+| |\n | |rte_device || |\n | | bus --------------------------------'\n | | ... ||\n | +----------------+|\n | ... |\n +-------------------+\n\nSigned-off-by: Shreyansh Jain <shreyansh.jain@nxp.com>\n---\n lib/librte_eal/bsdapp/eal/Makefile | 1 +\n lib/librte_eal/bsdapp/eal/rte_eal_version.map | 10 +++\n lib/librte_eal/common/Makefile | 2 +-\n lib/librte_eal/common/eal_common_bus.c | 97 +++++++++++++++++++++\n lib/librte_eal/common/include/rte_bus.h | 111 ++++++++++++++++++++++++\n lib/librte_eal/common/include/rte_dev.h | 1 +\n lib/librte_eal/linuxapp/eal/Makefile | 1 +\n lib/librte_eal/linuxapp/eal/rte_eal_version.map | 10 +++\n 8 files changed, 232 insertions(+), 1 deletion(-)\n create mode 100644 lib/librte_eal/common/eal_common_bus.c\n create mode 100644 lib/librte_eal/common/include/rte_bus.h", "diff": "diff --git a/lib/librte_eal/bsdapp/eal/Makefile b/lib/librte_eal/bsdapp/eal/Makefile\nindex a15b762..cce99f7 100644\n--- a/lib/librte_eal/bsdapp/eal/Makefile\n+++ b/lib/librte_eal/bsdapp/eal/Makefile\n@@ -78,6 +78,7 @@ SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_cpuflags.c\n SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_string_fns.c\n SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_hexdump.c\n SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_devargs.c\n+SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_bus.c\n SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_dev.c\n SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_options.c\n SRCS-$(CONFIG_RTE_EXEC_ENV_BSDAPP) += eal_common_thread.c\ndiff --git a/lib/librte_eal/bsdapp/eal/rte_eal_version.map b/lib/librte_eal/bsdapp/eal/rte_eal_version.map\nindex 2f81f7c..4dcf653 100644\n--- a/lib/librte_eal/bsdapp/eal/rte_eal_version.map\n+++ b/lib/librte_eal/bsdapp/eal/rte_eal_version.map\n@@ -174,3 +174,13 @@ DPDK_16.11 {\n \trte_eal_vdrv_unregister;\n \n } DPDK_16.07;\n+\n+DPDK_17.02 {\n+\tglobal:\n+\n+\trte_bus_list;\n+\trte_bus_dump;\n+\trte_bus_register;\n+\trte_bus_unregister;\n+\n+} DPDK_16.11;\ndiff --git a/lib/librte_eal/common/Makefile b/lib/librte_eal/common/Makefile\nindex 09a3d3a..240995c 100644\n--- a/lib/librte_eal/common/Makefile\n+++ b/lib/librte_eal/common/Makefile\n@@ -38,7 +38,7 @@ INC += rte_per_lcore.h rte_random.h\n INC += rte_tailq.h rte_interrupts.h rte_alarm.h\n INC += rte_string_fns.h rte_version.h\n INC += rte_eal_memconfig.h rte_malloc_heap.h\n-INC += rte_hexdump.h rte_devargs.h rte_dev.h rte_vdev.h\n+INC += rte_hexdump.h rte_devargs.h rte_bus.h rte_dev.h rte_vdev.h\n INC += rte_pci_dev_feature_defs.h rte_pci_dev_features.h\n INC += rte_malloc.h rte_keepalive.h rte_time.h\n \ndiff --git a/lib/librte_eal/common/eal_common_bus.c b/lib/librte_eal/common/eal_common_bus.c\nnew file mode 100644\nindex 0000000..c891392\n--- /dev/null\n+++ b/lib/librte_eal/common/eal_common_bus.c\n@@ -0,0 +1,97 @@\n+/*-\n+ * BSD LICENSE\n+ *\n+ * Copyright(c) 2016 NXP\n+ * All rights reserved.\n+ *\n+ * Redistribution and use in source and binary forms, with or without\n+ * modification, are permitted provided that the following conditions\n+ * are met:\n+ *\n+ * * Redistributions of source code must retain the above copyright\n+ * notice, this list of conditions and the following disclaimer.\n+ * * Redistributions in binary form must reproduce the above copyright\n+ * notice, this list of conditions and the following disclaimer in\n+ * the documentation and/or other materials provided with the\n+ * distribution.\n+ * * Neither the name of NXP nor the names of its\n+ * contributors may be used to endorse or promote products derived\n+ * from this software without specific prior written permission.\n+ *\n+ * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS\n+ * \"AS IS\" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT\n+ * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR\n+ * A PARTICULAR PURPOSE ARE DISCLAIMED.
