Padding to 0 bytes means that there is no wasted space - * in the font bitmaps (both on disk and in memory), but that access of - * the bitmaps will cause odd-address memory references. Padding to - * 2 bytes would ensure even address memory references and would - * be suitable for a 68010-class machine, but at the expense of wasted - * space in the font bitmaps. Padding to 4 bytes would be good - * for real 32 bit machines, etc. Be sure that you tell the font - * compiler what kind of padding you want because its defines are - * kept separate from this. See server/include/font.h for how - * GLYPHPADBYTES is used. - * - * Along with this, you should choose an appropriate value for - * GETLEFTBITS_ALIGNMENT, which is used in ddx/mfb/maskbits.h. This - * constant choses what kind of memory references are guarenteed during - * font access; either 1, 2 or 4, for byte, word or longword access, - * respectively. For instance, if you have decided to to have - * GLYPHPADBYTES == 4, then it is pointless for you to have a - * GETLEFTBITS_ALIGNMENT > 1, because the padding of the fonts has already - * guarenteed you that your fonts are longword aligned. On the other - * hand, even if you have chosen GLYPHPADBYTES == 1 to save space, you may - * also decide that the computing involved in aligning the pointer is more - * costly than an odd-address access; you choose GETLEFTBITS_ALIGNMENT == 1. - * - * Next, choose the tuning parameters which are appropriate for your - * hardware; these modify the behaviour of the raw frame buffer code - * in ddx/mfb and ddx/cfb. Defining these incorrectly will not cause - * the server to run incorrectly, but defining these correctly will - * cause some noticeable speed improvements: - * - * AVOID_MEMORY_READ - (8-bit cfb only) - * When stippling pixels on the screen (polytext and pushpixels), - * don't read long words from the display and mask in the - * appropriate values. Rather, perform multiple byte/short/long - * writes as appropriate. This option uses many more instructions - * but runs much faster when the destination is much slower than - * the CPU and at least 1 level of write buffer is availible (2 - * is much better). Defined currently for SPARC and MIPS. - * - * FAST_CONSTANT_OFFSET_MODE - (cfb and mfb) - * This define is used on machines which have no auto-increment - * addressing mode, but do have an effectively free constant-offset - * addressing mode. Currently defined for MIPS and SPARC, even though - * I remember the cg6 as performing better without it (cg3 definitely - * performs better with it). - * - * LARGE_INSTRUCTION_CACHE - - * This define increases the number of times some loops are - * unrolled. On 68020 machines (with 256 bytes of i-cache), - * this define will slow execution down as instructions miss - * the cache frequently. On machines with real i-caches, this - * reduces loop overhead, causing a slight performance improvement. - * Currently defined for MIPS and SPARC - * - * FAST_UNALIGNED_READS - - * For machines with more memory bandwidth than CPU, this - * define uses unaligned reads for 8-bit BitBLT instead of doing - * aligned reads and combining the results with shifts and - * logical-ors. Currently defined for 68020 and vax. - * PLENTIFUL_REGISTERS - - * For machines with > 20 registers. Currently used for - * unrolling the text painting code a bit more. Currently - * defined for MIPS. - * SHARED_IDCACHE - - * For non-Harvard RISC machines, those which share the same - * CPU memory bus for instructions and data.
