This\ninterface allows the core code to operate in PF mode (direct\nhardware access) or bifurcated mode (hardware configured via\nkernel driver). This driver currently only supports PF modei,\nbut bifurcated mode will be added in a future patch-set.\nNote that the flexible interface is not used for data path\noperations, and thus there are no performance concerns\nrelated to the use of function pointers.\n\nSigned-off-by: Timothy McDaniel <timothy.mcdaniel@intel.com>\n---\n drivers/event/dlb/dlb.c | 1 +\n drivers/event/dlb/dlb_iface.c | 27 +++++++++++++++++++++++++++\n drivers/event/dlb/dlb_iface.h | 27 +++++++++++++++++++++++++++\n drivers/event/dlb/meson.build | 1 +\n drivers/event/dlb/pf/dlb_pf.c | 1 +\n 5 files changed, 57 insertions(+)\n create mode 100644 drivers/event/dlb/dlb_iface.c\n create mode 100644 drivers/event/dlb/dlb_iface.h", "diff": "diff --git a/drivers/event/dlb/dlb.c b/drivers/event/dlb/dlb.c\nindex 1659f93..8008a50 100644\n--- a/drivers/event/dlb/dlb.c\n+++ b/drivers/event/dlb/dlb.c\n@@ -33,6 +33,7 @@\n #include <rte_eventdev_pmd.h>\n \n #include \"dlb_priv.h\"\n+#include \"dlb_iface.h\"\n #include \"dlb_inline_fns.h\"\n \n /*\ndiff --git a/drivers/event/dlb/dlb_iface.c b/drivers/event/dlb/dlb_iface.c\nnew file mode 100644\nindex 0000000..dd72120\n--- /dev/null\n+++ b/drivers/event/dlb/dlb_iface.c\n@@ -0,0 +1,27 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright(c) 2016-2020 Intel Corporation\n+ */\n+\n+#include <stdint.h>\n+\n+#include \"dlb_priv.h\"\n+\n+/* DLB PMD Internal interface function pointers.\n+ * If VDEV (bifurcated PMD), these will resolve to functions that issue ioctls\n+ * serviced by DLB kernel module.\n+ * If PCI (PF PMD), these will be implemented locally in user mode.\n+ */\n+\n+void (*dlb_iface_low_level_io_init)(struct dlb_eventdev *dlb);\n+\n+int (*dlb_iface_open)(struct dlb_hw_dev *handle, const char *name);\n+\n+int (*dlb_iface_get_device_version)(struct dlb_hw_dev *handle,\n+\t\t\t\t uint8_t *revision);\n+\n+int (*dlb_iface_get_num_resources)(struct dlb_hw_dev *handle,\n+\t\t\t\t struct dlb_get_num_resources_args *rsrcs);\n+\n+int (*dlb_iface_get_cq_poll_mode)(struct dlb_hw_dev *handle,\n+\t\t\t\t enum dlb_cq_poll_modes *mode);\n+\ndiff --git a/drivers/event/dlb/dlb_iface.h b/drivers/event/dlb/dlb_iface.h\nnew file mode 100644\nindex 0000000..416d1b3\n--- /dev/null\n+++ b/drivers/event/dlb/dlb_iface.h\n@@ -0,0 +1,27 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ * Copyright(c) 2016-2020 Intel Corporation\n+ */\n+\n+#ifndef _DLB_IFACE_H\n+#define _DLB_IFACE_H\n+\n+/* DLB PMD Internal interface function pointers.\n+ * If VDEV (bifurcated PMD), these will resolve to functions that issue ioctls\n+ * serviced by DLB kernel module.\n+ * If PCI (PF PMD), these will be implemented locally in user mode.\n+ */\n+\n+extern void (*dlb_iface_low_level_io_init)(struct dlb_eventdev *dlb);\n+\n+extern int (*dlb_iface_open)(struct dlb_hw_dev *handle, const char *name);\n+\n+extern int (*dlb_iface_get_device_version)(struct dlb_hw_dev *handle,\n+\t\t\t\t\t uint8_t *revision);\n+\n+extern int (*dlb_iface_get_num_resources)(struct dlb_hw_dev *handle,\n+\t\t\t\t struct dlb_get_num_resources_args *rsrcs);\n+\n+extern int (*dlb_iface_get_cq_poll_mode)(struct dlb_hw_dev *handle,\n+\t\t\t\t\t enum dlb_cq_poll_modes *mode);\n+\n+#endif /* _DLB_IFACE_H */\ndiff --git a/drivers/event/dlb/meson.build b/drivers/event/dlb/meson.build\nindex b4bdc8b..8707d3d 100644\n--- a/drivers/event/dlb/meson.build\n+++ b/drivers/event/dlb/meson.build\n@@ -8,6 +8,7 @@ if not is_linux or not dpdk_conf.has('RTE_ARCH_X86_64')\n endif\n \n sources = files('dlb.c',\n+\t\t'dlb_iface.c',\n \t\t'pf/dlb_main.c',\n \t\t'pf/dlb_pf.c'\n )\ndiff --git a/drivers/event/dlb/pf/dlb_pf.c b/drivers/event/dlb/pf/dlb_pf.c\nindex 3f836f3..05fd76c 100644\n--- a/drivers/event/dlb/pf/dlb_pf.c\n+++ b/drivers/event/dlb/pf/dlb_pf.c\n@@ -27,6 +27,7 @@\n #include <rte_string_fns.h>\n \n #include \"../dlb_priv.h\"\n+#include \"../dlb_iface.h\"\n #include \"../dlb_inline_fns.h\"\n #include \"dlb_main.h\"\n #include \"base/dlb_hw_types.h\"\n", "prefixes": [ "v11", "07/23" ] }
