915 | /* ALU | |
916 | // The ALU instructions register blocks are enumerated according to the order | |
917 | // in which fglrx. I assume there is space for 64 instructions, since | |
918 | // each block has space for a maximum of 64 DWORDs, and this matches reported | |
919 | // native limits. | |
920 | // | |
921 | // The basic functional block seems to be one MAD for each color and alpha, | |
922 | // and an adder that adds all components after the MUL. | |
923 | // - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands | |
924 | // - DP4: Use OUTC_DP4, OUTA_DP4 | |
925 | // - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands | |
926 | // - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands | |
927 | // - CMP: If ARG2 < 0, return ARG1, else return ARG0 | |
928 | // - FLR: use FRC+MAD | |
929 | // - XPD: use MAD+MAD | |
930 | // - SGE, SLT: use MAD+CMP | |
931 | // - RSQ: use ABS modifier for argument | |
932 | // - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP) | |
933 | // into color register | |
934 | // - apparently, there's no quick DST operation | |
935 | // - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2" | |
936 | // - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0" | |
937 | // - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1" | |
938 | // | |
939 | // Operand selection | |
940 | // First stage selects three sources from the available registers and | |
941 | // constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha). | |
942 | // fglrx sorts the three source fields: Registers before constants, | |
943 | // lower indices before higher indices; I do not know whether this is necessary. | |
944 | // fglrx fills unused sources with "read constant 0" | |
945 | // According to specs, you cannot select more than two different constants. | |
946 | // | |
947 | // Second stage selects the operands from the sources. This is defined in | |
948 | // INSTR0 (color) and INSTR2 (alpha). You can also select the special constants | |
949 | // zero and one. | |
950 | // Swizzling and negation happens in this stage, as well. | |
951 | // | |
952 | // Important: Color and alpha seem to be mostly separate, i.e. their sources | |
953 | // selection appears to be fully independent (the register storage is probably | |
954 | // physically split into a color and an alpha section). | |
955 | // However (because of the apparent physical split), there is some interaction | |
956 | // WRT swizzling. If, for example, you want to load an R component into an | |
957 | // Alpha operand, this R component is taken from a *color* source, not from | |
958 | // an alpha source. The corresponding register doesn't even have to appear in | |
959 | // the alpha sources list. (I hope this alll makes sense to you) | |
960 | // | |
961 | // Destination selection | |
962 | // The destination register index is in FPI1 (color) and FPI3 (alpha) together | |
963 | // with enable bits. | |
964 | // There are separate enable bits for writing into temporary registers | |
965 | // (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_* /DSTA_OUTPUT). | |
966 | // You can write to both at once, or not write at all (the same index | |
967 | // must be used for both). | |
968 | // | |
969 | // Note: There is a special form for LRP | |
970 | // - Argument order is the same as in ARB_fragment_program. | |
971 | // - Operation is MAD | |
972 | // - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP | |
973 | // - Set FPI0/FPI2_SPECIAL_LRP | |
974 | // Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */ | |
