This is defined in INSTR1 (color) and INSTR3 (alpha). 1916 * fglrx sorts the three source fields: Registers before constants, 1917 * lower indices before higher indices; I do not know whether this is 1918 * necessary. 1919 * 1920 * fglrx fills unused sources with "read constant 0" 1921 * According to specs, you cannot select more than two different constants. 1922 * 1923 * Second stage selects the operands from the sources. This is defined in 1924 * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants 1925 * zero and one. 1926 * Swizzling and negation happens in this stage, as well. 1927 * 1928 * Important: Color and alpha seem to be mostly separate, i.e. their sources 1929 * selection appears to be fully independent (the register storage is probably 1930 * physically split into a color and an alpha section). 1931 * However (because of the apparent physical split), there is some interaction 1932 * WRT swizzling. If, for example, you want to load an R component into an 1933 * Alpha operand, this R component is taken from a *color* source, not from 1934 * an alpha source. The corresponding register doesn't even have to appear in 1935 * the alpha sources list. (I hope this all makes sense to you) 1936 * 1937 * Destination selection 1938 * The destination register index is in FPI1 (color) and FPI3 (alpha) 1939 * together with enable bits. 1940 * There are separate enable bits for writing into temporary registers 1941 * (DSTC_REG_* /DSTA_REG) and program output registers (DSTC_OUTPUT_* 1942 * /DSTA_OUTPUT). You can write to both at once, or not write at all (the 1943 * same index must be used for both). 1944 * 1945 * Note: There is a special form for LRP 1946 * - Argument order is the same as in ARB_fragment_program. 1947 * - Operation is MAD 1948 * - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP 1949 * - Set FPI0/FPI2_SPECIAL_LRP 1950 * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD 1951 */ 1952 #define R300_US_ALU_RGB_ADDR_0 0x46C0 1953 #
