/*
 * Graphics Commands, 'xxx' parts may be generated from ucode
 *
 * The command format is
 *
 *  |00xxxxxx| = DMA        0,..,127
 *  |10xxxxxx| = Immediate Mode -65,..,-128
 *  |11xxxxxx| = RDP cmds       -1,..,-64
 *
 * Note: in order for the RSP microcode to process RDP commands opaquely,
 * we need to further identify those RDP commands that need DRAM address
 * "fixup". To do this, we have the dummy command G_RDP_ADDR_FIXUP, and
 * all |RDP commands| less than this are commands with embedded DRAM
 * addresses. Further, the format of these commands should be similar so
 * only one fixup routine is needed.
 *
 * Further explanation:
 * The names of the commands are somewhat misleading. Here is clarification:
 *
 *  - a 'DMA' type command has a pointer to additional data and
 *    causes a DMA transfer to bring that into DMEM.
 *
 *  - an 'Immediate' type command isn't really 'immediate', in the
 *    traditional sense. This just means that the entire command fits
 *    in the 64-bit word, and the ucode can execute it 'immediately'
 *    without additional memory transfers.
 *
 *  - an 'RDP' command is identified as such because the RDP
 *    commands can be passed-thru the RSP and sent to the RDP
 *    directly. One further confusing thing, is that some 'DP'
 *    macros below actually generate immediate commands, not
 *    not direct DP commands.
 *
 * IMPLEMENTATION NOTE:
 * There is another group of RDP commands that includes the triangle commands
 * generated by the RSP code. These are the raw commands the rasterizer 
 * hardware chews on, with slope info, etc. They will follow the RDP 
 * ordering...
 *
 * IMPLEMENTATION NOTE:
 * The RDP hardware has some of these bit patterns wired up. If the hardware 
 * changes, we must adjust this table, likewise we can't change/add things 
 * once the hardware is frozen. (actually, the RDP hardware only looks at
 * the lower 6 bits of the command byte)

/*
 * Data Structures
 *
 * NOTE:
 * The DMA transfer hardware requires 64-bit aligned, 64-bit multiple-
 * sized transfers. This important hardware optimization is unfortunately
 * reflected in the programming interface, with some structures
 * padded and alignment enforced.
 *
 * Since structures are aligned to the boundary of the "worst-case"
 * element, we can't depend on the C compiler to align things
 * properly.
 *
 * 64-bit structure alignment is enforced by wrapping structures with 
 * unions that contain a dummy "long long int".  Why this works is
 * explained in the ANSI C Spec, or on page 186 of the second edition
 * of K&R, "The C Programming Language".
 *
 * The price we pay for this is a little awkwardness referencing the
 * structures through the union. There is no memory penalty, since
 * all the structures are at least 64-bits the dummy alignment field
 * does not increase the size of the union.
 *
 * Static initialization of these union structures works because
 * the ANSI C spec states that static initialization for unions
 * works by using the first union element. We put the dummy alignment
 * field last for this reason.
 *
 * (it's possible a newer 64-bit compiler from MIPS might make this
 * easier with a flag, but we can't wait for it...)
