It means keep origin option, create new one and add deprecate message to origin that scripts should be converted. After 3-4 releases we can remove it which should be enough time for users to do transition.I agree with you.

I mean it is fine how it is but maybe in future would make sense to have -b and -p together to be able to generate both of these fields.Definitely showing product information is key part here at least for me.Yes, that makes sense. I'll change these commands to 'gen_board' and 'gen_product' with adding back the previous command 'board_gen' to keep its compatibility. A command which can generate both board and product into a single FRU could be added later using a separate series.; #endif diff --git a/include/fru.h b/include/fru.h index b158b80b5866..2b19033a3843 100644 --- a/include/fru.h +++ b/include/fru.h @@ -31,7 +31,13 @@ struct fru_board_info_header { u8 time[3]; } __packed; -struct fru_board_info_member { +struct fru_product_info_header { + u8 ver; + u8 len; + u8 lang_code; +} __packed; + +struct fru_common_info_member { u8 type_len; u8 *name; } __packed; @@ -64,6 +70,27 @@ struct fru_board_data { struct list_head custom_fields; }; +struct fru_product_data { + u8 ver; + u8 len; + u8 lang_code; + u8 manufacturer_type_len; + u8 manufacturer_name[FRU_INFO_FIELD_LEN_MAX]; + u8 product_name_type_len; + u8 product_name[FRU_INFO_FIELD_LEN_MAX]; + u8 part_number_type_len; + u8 part_number[FRU_INFO_FIELD_LEN_MAX]; + u8 version_number_type_len; + u8 version_number[FRU_INFO_FIELD_LEN_MAX]; + u8 serial_number_type_len; + u8 serial_number[FRU_INFO_FIELD_LEN_MAX]; + u8 asset_number_type_len; + u8 asset_number[FRU_INFO_FIELD_LEN_MAX]; + u8 file_id_type_len; + u8 file_id[FRU_INFO_FIELD_LEN_MAX]; + struct list_head custom_fields; +}; + struct fru_multirec_hdr { u8 rec_type; u8 type; @@ -85,6 +112,7 @@ struct fru_multirec_node { struct fru_table { struct fru_common_hdr hdr; struct fru_board_data brd; + struct fru_product_data prd; struct list_head multi_recs; bool captured; }; @@ -102,13 +130,15 @@ struct fru_table { /* This should be minimum of fields */ #define FRU_BOARD_AREA_TOTAL_FIELDS 5 +#define FRU_PRODUCT_AREA_TOTAL_FIELDS 7 #define FRU_TYPELEN_TYPE_SHIFT 6 #define FRU_TYPELEN_TYPE_BINARY 0 #define FRU_TYPELEN_TYPE_ASCII8 3 int fru_display(int verbose); int fru_capture(const void *addr); -int fru_generate(const void *addr, int argc, char *const argv[]); +int fru_board_generate(const void *addr, int argc, char *const argv[]); +int fru_product_generate(const void *addr, int argc, char *const argv[]); u8 fru_checksum(u8 *addr, u8 len); int fru_check_type_len(u8 type_len, u8 language, u8 *type); const struct fru_table *fru_get_fru_data(void); diff --git a/lib/fru_ops.c b/lib/fru_ops.c index a25ebccd110d..978d5f8e8a19 100644 --- a/lib/fru_ops.c +++ b/lib/fru_ops.c @@ -16,9 +16,18 @@ struct fru_table fru_data __section(".data") = { .brd.custom_fields = LIST_HEAD_INIT(fru_data.brd.custom_fields), + .prd.custom_fields = LIST_HEAD_INIT(fru_data.prd.custom_fields), .multi_recs = LIST_HEAD_INIT(fru_data.multi_recs), }; +static const char * const fru_typecode_str[] = { + "Binary/Unspecified", + "BCD plus", + "6-bit ASCII", + "8-bit ASCII", + "2-byte UNICODE" +};This can be done via separate patch to make this one smaller and easier to review.It's just moved out from 'fru_display_board' function because it can be used for both 'fru_display_board' and 'fru_display_product' functions. Definately it's a part of this patch and I don't think that it should be submitted using a seperate patch.
No doubt that that it can stay here. It is more about to have just small patches which is much much easier to review. It means if one patch moves this structure to common location for using for product area generation. I need to review 20 LOC. And this patch is smaller which is again easier to review without distraction from obvious/easy going changes.
Thanks, Michal
