- * Machine dependent values:
- * GLYPHPADBYTES should be chosen with consideration for the space-time
- * trade-off. 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. This unrolls some
- * solid fill loops which are otherwise best left rolled up.
- * Currently defined for SPARC.
