From 7fe2d98070e05f3f11a57b972f7377b14da513c9 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Fri, 17 Sep 2021 22:43:03 +0800 Subject: [PATCH] net/ice/base: add parser create and destroy skeleton Add new parser module which can parse a packet in binary and generate information like ptype, protocol/offset pairs and flags which can be used to feed the FXP profile creation directly. The patch added skeleton of the parser instance create and destroy APIs: ice_parser_create ice_parser_destroy Signed-off-by: Qi Zhang Acked-by: Junfeng Guo --- drivers/net/ice/base/ice_common.h | 1 + drivers/net/ice/base/ice_flex_pipe.c | 2 +- drivers/net/ice/base/ice_flex_pipe.h | 5 ++++ drivers/net/ice/base/ice_parser.c | 34 ++++++++++++++++++++++++++++ drivers/net/ice/base/ice_parser.h | 14 ++++++++++++ drivers/net/ice/base/meson.build | 1 + 6 files changed, 56 insertions(+), 1 deletion(-) create mode 100644 drivers/net/ice/base/ice_parser.c create mode 100644 drivers/net/ice/base/ice_parser.h diff --git a/drivers/net/ice/base/ice_common.h b/drivers/net/ice/base/ice_common.h index 1d8882c279..a3cbf4fb05 100644 --- a/drivers/net/ice/base/ice_common.h +++ b/drivers/net/ice/base/ice_common.h @@ -8,6 +8,7 @@ #include "ice_type.h" #include "ice_nvm.h" #include "ice_flex_pipe.h" +#include "ice_parser.h" #include "ice_switch.h" #include "ice_fdir.h" diff --git a/drivers/net/ice/base/ice_flex_pipe.c b/drivers/net/ice/base/ice_flex_pipe.c index 3631ddba2c..703c3e0416 100644 --- a/drivers/net/ice/base/ice_flex_pipe.c +++ b/drivers/net/ice/base/ice_flex_pipe.c @@ -284,7 +284,7 @@ ice_pkg_enum_section(struct ice_seg *ice_seg, struct ice_pkg_enum *state, * indicates a base offset of 10, and the index for the entry is 2, then * section handler function should set the offset to 10 + 2 = 12. */ -static void * +void * ice_pkg_enum_entry(struct ice_seg *ice_seg, struct ice_pkg_enum *state, u32 sect_type, u32 *offset, void *(*handler)(u32 sect_type, void *section, diff --git a/drivers/net/ice/base/ice_flex_pipe.h b/drivers/net/ice/base/ice_flex_pipe.h index b690be75fc..045a77c607 100644 --- a/drivers/net/ice/base/ice_flex_pipe.h +++ b/drivers/net/ice/base/ice_flex_pipe.h @@ -94,4 +94,9 @@ void ice_pkg_buf_free(struct ice_hw *hw, struct ice_buf_build *bld); enum ice_status ice_set_key(u8 *key, u16 size, u8 *val, u8 *upd, u8 *dc, u8 *nm, u16 off, u16 len); +void * +ice_pkg_enum_entry(struct ice_seg *ice_seg, struct ice_pkg_enum *state, + u32 sect_type, u32 *offset, + void *(*handler)(u32 sect_type, void *section, + u32 index, u32 *offset)); #endif /* _ICE_FLEX_PIPE_H_ */ diff --git a/drivers/net/ice/base/ice_parser.c b/drivers/net/ice/base/ice_parser.c new file mode 100644 index 0000000000..c08decaf0d --- /dev/null +++ b/drivers/net/ice/base/ice_parser.c @@ -0,0 +1,34 @@ +/* SPDX-License-Identifier: BSD-3-Clause + * Copyright(c) 2001-2021 Intel Corporation + */ + +#include "ice_common.h" + +/** + * ice_parser_create - create a parser instance + * @hw: pointer to the hardware structure + * @psr: output parameter for a new parser instance be created + */ +enum ice_status ice_parser_create(struct ice_hw *hw, struct ice_parser **psr) +{ + struct ice_parser *p; + + p = (struct ice_parser *)ice_malloc(hw, sizeof(struct ice_parser)); + + if (!p) + return ICE_ERR_NO_MEMORY; + + p->hw = hw; + + *psr = p; + return ICE_SUCCESS; +} + +/** + * ice_parser_destroy - destroy a parser instance + * @psr: pointer to a parser instance + */ +void ice_parser_destroy(struct ice_parser *psr) +{ + ice_free(psr->hw, psr); +} diff --git a/drivers/net/ice/base/ice_parser.h b/drivers/net/ice/base/ice_parser.h new file mode 100644 index 0000000000..5964bf4e49 --- /dev/null +++ b/drivers/net/ice/base/ice_parser.h @@ -0,0 +1,14 @@ +/* SPDX-License-Identifier: BSD-3-Clause + * Copyright(c) 2001-2021 Intel Corporation + */ + +#ifndef _ICE_PARSER_H_ +#define _ICE_PARSER_H_ + +struct ice_parser { + struct ice_hw *hw; /* pointer to the hardware structure */ +}; + +enum ice_status ice_parser_create(struct ice_hw *hw, struct ice_parser **psr); +void ice_parser_destroy(struct ice_parser *psr); +#endif /* _ICE_PARSER_H_ */ diff --git a/drivers/net/ice/base/meson.build b/drivers/net/ice/base/meson.build index be9713dfa1..3051b474ad 100644 --- a/drivers/net/ice/base/meson.build +++ b/drivers/net/ice/base/meson.build @@ -15,6 +15,7 @@ sources = [ 'ice_acl_ctrl.c', 'ice_vlan_mode.c', 'ice_ptp_hw.c', + 'ice_parser.c', ] error_cflags = [ -- 2.20.1
