This is -* achieved by checking the "bottom" or "role" fields of these structures. Since these fields are restricted -* to a limited range, comparing the contents to a value with a known endian-ess gives a clue to their actual -* endianness. -* -*.DIAGRAM -*1a: The role-field of the actor structure has a known non-zero, not "byte symmetric" value (namely -* COMP_ROLE_ACT or 0x0001), so if and only the contents of this field matches COMP_ROLE_ACT (in Native -* Endian format), the actor structure is Native Endian. -*2a: Since the role-field of the supplier structure is 0x0000, the test as used for the actor does not work -* for a supplier. A supplier has always exactly 1 variant,top,bottom record with (officially, but see the -* note below) each of these 3 values in the range 1 through 99, so one byte of the word value of variant, -* top and bottom words is 0x00 and the other byte is non-zero. Whether the lowest address byte or the -* highest address byte is non-zero depends on the Endianness of the LTV. If and only if the word value of -* bottom is less than 0x0100, the supplier is Native Endian. -* NOTE: the variant field of the supplier structure can not be used for the Endian Detection Algorithm, -* because a a zero-valued variant has been used as Controlled Deployment indication in the past. -* Note: An actor may have multiple sets of variant,top,bottom records, including dummy sets with variant, -* top and bottom fields with a zero-value. As a consequence the endianness of the actor can not be determined -* based on its variant,top,bottom values. -* -* Note: the L and T field of the structures are always in Native Endian format, so you can not draw -* conclusions concerning the Endianness of the structure based on these two fields. -* -*1b/2b -* The only purpose of the CFG_RANGE_SPEC_BYTE_STRCT is to give easy access to the non-zero byte of the word -* value of variant, top and bottom. The variables sup_endian and act_endian are used for the supplier and -* actor structure respectively. These variables must be 0 when the structure has LE format and 1 if the -* structure has BE format. This can be phrased as: -* the variable is false (i.e 0x0000) if either -* (the platform is LE and the LTV is the same as the platform) -* or -* (the platform is BE and the LTV differs from the platform). -* the variable is true (i.e 0x0001) if either -* (the platform is BE and the LTV is the same as the platform) -* or -* (the platform is LE and the LTV differs from the platform). -* -* Alternatively this can be phrased as: -* if the platform is LE -* if the LTV is LE (i.e the same as the platform), then the variable = 0 -* else (the LTV is BE (i.e. different from the platform) ), then the variable = 1 -* if the platform is BE -* if the LTV is BE (i.e the same as the platform), then the variable = 1 -* else (the LTV is LE (i.e. different from the platform) ), then the variable = 0 -* -* This is implemented as: -* #if HCF_BIG_ENDIAN == 0 //platform is LE -* sup/act_endian becomes reverse of structure-endianness as determined in 1a/1b -* #endif -*6: Each of the actor variant-bottom-top records is checked against the (single) supplier variant-bottom-top -* range till either an acceptable match is found or all actor records are tried. As explained above, due to -* the limited ranges of these values, checking a byte is acceptable and suitable. -*8: depending on whether a match was found or not (as reflected by the value of the control variable of the -* for loop), the NULL pointer or a pointer to the matching Number/Bottom/Top record of the Actor structure -* is returned. -* As an additional safety, checking the supplier length protects against invalid Supplier structures, which -* may be caused by failing hcf_get_info (in which case the len-field is zero). Note that the contraption -* "supp->len != sizeof(CFG_SUP_RANGE_STRCT)/sizeof(hcf_16) - 1" -* did turn out not to work for a compiler which padded the structure definition. -* -* Note: when consulting references like DesignNotes and Architecture specifications there is a confusing use -* of the notions number and variant. This resulted in an inconsistent use in the HCF nomenclature as well. -* This makes the logic hard to follow and one has to be very much aware of the context when walking through -* the code. -* NOTE: The Endian Detection Algorithm places limitations on future extensions of the fields, i.e. they should -* stay within the currently defined boundaries of 1 through 99 (although 1 through 255) would work as well -* and there should never be used a zero value for the bottom of a valid supplier. -* Note: relative to Asserts, the following can be observed: -* 1: Supplier variant 0x0000 has been used for Controlled Deployment -* 2: An actor may have one or more variant record specifications with a top of zero and a non-zero bottom -* to override the HCF default support of a particular variant by the MSF programmer via hcfcfg.h -* 3: An actor range can be specified as all zeros, e.g. as padding in the automatically generated firmware -* image files. -*.ENDDOC END DOCUMENTATION -*************************************************************************************************************/ -CFG_RANGE_SPEC_STRCT* -mmd_check_comp( CFG_RANGES_STRCT *actp, CFG_SUP_RANGE_STRCT *supp ) -{ - -CFG_RANGE_SPEC_BYTE_STRCT *actq = (CFG_RANGE_SPEC_BYTE_STRCT*)actp->var_rec; -CFG_RANGE_SPEC_BYTE_STRCT *supq = (CFG_RANGE_SPEC_BYTE_STRCT*)&(supp->variant); -hcf_16 i; -int act_endian; //actor endian flag -int sup_endian; //supplier endian flag - - act_endian = actp->role == COMP_ROLE_ACT; //true if native endian /* 1a */ - sup_endian = supp->bottom < 0x0100; //true if native endian /* 2a */ - -#if HCF_ASSERT - MMDASSERT( supp->len == 6, supp->len ) - MMDASSERT( actp->len >= 6 && actp->len%3 == 0, actp->len ) - - if ( act_endian ) { //native endian - MMDASSERT( actp->role == COMP_ROLE_ACT, actp->role ) - MMDASSERT( 1 <= actp->id && actp->id <= 99, actp->id ) - } else { //non-native endian - MMDASSERT( actp->role == CNV_END_SHORT(COMP_ROLE_ACT), actp->role ) - MMDASSERT( 1 <= CNV_END_SHORT(actp->id) && CNV_END_SHORT(actp->id) <= 99, actp->id ) - } - if ( sup_endian ) { //native endian - MMDASSERT( supp->role == COMP_ROLE_SUPL, supp->role ) - MMDASSERT( 1 <= supp->id && supp->id <= 99, supp->id ) - MMDASSERT( 1 <= supp->variant && supp->variant <= 99, supp->variant ) - MMDASSERT( 1 <= supp->bottom && supp->bottom <= 99, supp->bottom ) - MMDASSERT( 1 <= supp->top && supp->top <= 99, supp->top ) - MMDASSERT( supp->bottom <= supp->top, supp->bottom << 8 | supp->top ) - } else { //non-native endian - MMDASSERT( supp->role == CNV_END_SHORT(COMP_ROLE_SUPL), supp->role ) - MMDASSERT( 1 <= CNV_END_SHORT(supp->id) && CNV_END_SHORT(supp->id) <= 99, supp->id ) - MMDASSERT( 1 <= CNV_END_SHORT(supp->variant) && CNV_END_SHORT(supp->variant) <= 99, supp->variant ) - MMDASSERT( 1 <= CNV_END_SHORT(supp->bottom) && CNV_END_SHORT(supp->bottom) <=99, supp->bottom ) - MMDASSERT( 1 <= CNV_END_SHORT(supp->top) && CNV_END_SHORT(supp->top) <=99, supp->top ) - MMDASSERT( CNV_END_SHORT(supp->bottom) <= CNV_END_SHORT(supp->top), supp->bottom << 8 | supp->top ) - } -#endif // HCF_ASSERT - -#if HCF_BIG_ENDIAN == 0 - act_endian = !act_endian; /* 1b*/ - sup_endian = !sup_endian; /* 2b*/ -#endif // HCF_BIG_ENDIAN - - for ( i = actp->len ; i > 3; actq++, i -= 3 ) { /* 6 */ - MMDASSERT( actq->variant[act_endian] <= 99, i<<8 | actq->variant[act_endian] ) - MMDASSERT( actq->bottom[act_endian] <= 99 , i<<8 | actq->bottom[act_endian] ) - MMDASSERT( actq->top[act_endian] <= 99 , i<<8 | actq->top[act_endian] ) - MMDASSERT( actq->bottom[act_endian] <= actq->top[act_endian], i<<8 | actq->bottom[act_endian] ) - if ( actq->variant[act_endian] == supq->variant[sup_endian] && - actq->bottom[act_endian] <= supq->top[sup_endian] && - actq->top[act_endian] >= supq->bottom[sup_endian] - ) break; - } - if ( i <= 3 || supp->len != 6 /*sizeof(CFG_SUP_RANGE_STRCT)/sizeof(hcf_16) - 1 */ ) { - actq = NULL; /* 8 */ - } -#if HCF_ASSERT - if ( actq == NULL ) { - for ( i = 0; i <= supp->len; i += 2 ) { - MMDASSERT( DO_ASSERT, MERGE_2( ((hcf_16*)supp)[i], ((hcf_16*)supp)[i+1] ) ); - } - for ( i = 0; i <= actp->len; i += 2 ) { - MMDASSERT( DO_ASSERT, MERGE_2( ((hcf_16*)actp)[i], ((hcf_16*)actp)[i+1] ) ); - } - } -#endif // HCF_ASSERT - return (CFG_RANGE_SPEC_STRCT*)actq; -} // mmd_check_comp - |
