Message-Id: <20230821081438.2937934-2-junfeng.guo@intel.com> Date: Mon, 21 Aug 2023 16:14:24 +0800 From: Junfeng Guo <junfeng.guo@...el.com> To: intel-wired-lan@...ts.osuosl.org Cc: netdev@...r.kernel.org, anthony.l.nguyen@...el.com, jesse.brandeburg@...el.com, qi.z.zhang@...el.com, ivecera@...hat.com, sridhar.samudrala@...el.com, horms@...nel.org, Junfeng Guo <junfeng.guo@...el.com> Subject: [PATCH iwl-next v6 01/15] ice: 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 create and destroy APIs: ice_parser_create ice_parser_destroy Signed-off-by: Junfeng Guo <junfeng.guo@...el.com> --- drivers/net/ethernet/intel/ice/ice_common.h | 4 +++ drivers/net/ethernet/intel/ice/ice_ddp.c | 10 +++---- drivers/net/ethernet/intel/ice/ice_ddp.h | 13 ++++++++ drivers/net/ethernet/intel/ice/ice_parser.c | 33 +++++++++++++++++++++ drivers/net/ethernet/intel/ice/ice_parser.h | 13 ++++++++ 5 files changed, 68 insertions(+), 5 deletions(-) create mode 100644 drivers/net/ethernet/intel/ice/ice_parser.c create mode 100644 drivers/net/ethernet/intel/ice/ice_parser.h diff --git a/drivers/net/ethernet/intel/ice/ice_common.h b/drivers/net/ethernet/intel/ice/ice_common.h index 8ba5f935a092..528dde976373 100644 --- a/drivers/net/ethernet/intel/ice/ice_common.h +++ b/drivers/net/ethernet/intel/ice/ice_common.h @@ -9,10 +9,14 @@ #include "ice_type.h" #include "ice_nvm.h" #include "ice_flex_pipe.h" +#include "ice_parser.h" #include <linux/avf/virtchnl.h> #include "ice_switch.h" #include "ice_fdir.h" +#define BITS_PER_WORD 16 +#define BITMAP_MASK(n) GENMASK(((n) - 1), 0) + #define ICE_SQ_SEND_DELAY_TIME_MS 10 #define ICE_SQ_SEND_MAX_EXECUTE 3 diff --git a/drivers/net/ethernet/intel/ice/ice_ddp.c b/drivers/net/ethernet/intel/ice/ice_ddp.c index d71ed210f9c4..3bdf03b9ee71 100644 --- a/drivers/net/ethernet/intel/ice/ice_ddp.c +++ b/drivers/net/ethernet/intel/ice/ice_ddp.c @@ -288,11 +288,11 @@ void *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 *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)) +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)) { void *entry;
