901// - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
902// - DP4: Use OUTC_DP4, OUTA_DP4
903// - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
904// - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands

906// - FLR: use FRC+MAD
907// - XPD: use MAD+MAD
908// - SGE, SLT: use MAD+CMP
909// - RSQ: use ABS modifier for argument
910// - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP)
911// into color register
912// - apparently, there's no quick DST operation
913// - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
914// - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
915// - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
916//
917// Operand selection
918// First stage selects three sources from the available registers and
919// constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
920// fglrx sorts the three source fields: Registers before constants,
921// lower indices before higher indices; I do not know whether this is necessary.
922// fglrx fills unused sources with "read constant 0"
923// According to specs, you cannot select more than two different constants.
924//
925// Second stage selects the operands from the sources. This is defined in
926// INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
927// zero and one.
928// Swizzling and negation happens in this stage, as well.
929//
930// Important: Color and alpha seem to be mostly separate, i.e. their sources
931// selection appears to be fully independent (the register storage is probably
932// physically split into a color and an alpha section).
933// However (because of the apparent physical split), there is some interaction
934// WRT swizzling. If, for example, you want to load an R component into an
935// Alpha operand, this R component is taken from a *color* source, not from
936// an alpha source. The corresponding register doesn't even have to appear in
937// the alpha sources list. (I hope this alll makes sense to you)
938//
939// Destination selection
940// The destination register index is in FPI1 (color) and FPI3 (alpha) together
941// with enable bits.
942// There are separate enable bits for writing into temporary registers
943// (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_* /DSTA_OUTPUT).
944// You can write to both at once, or not write at all (the same index
945// must be used for both).
946//
947// Note: There is a special form for LRP
948// - Argument order is the same as in ARB_fragment_program.
949// - Operation is MAD
950// - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
951// - Set FPI0/FPI2_SPECIAL_LRP
952// Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */

42 * 2.1 Scissors registers managed by the DRM, 3D operations clipped by
43 * cliprects of the cmdbuf ioctl
44 * 2.2 Implemented SAVAGE_CMD_DMA_IDX and SAVAGE_CMD_VB_IDX
45 * 2.3 Event counters used by BCI_EVENT_EMIT/WAIT ioctls are now 32 bits
46 * wide and thus very long lived (unlikely to ever wrap). The size
47 * in the struct was 32 bits before, but only 16 bits were used
48 * 2.4 Implemented command DMA. Now drm_savage_init_t.cmd_dma_offset is
49 * actually used
