Not Bresenham. * DashedLine with non-power-of-two pattern length: Apparently, there is * no way to set the length of the pattern -- it is always * assumed to be 8 or 32 (or 1024?). * ScreenToScreenColorExpandFill: See p. 4-17 of the Technical Reference * Manual where it states that monochrome expansion of frame * buffer data is not supported. * CPUToScreenColorExpandFill, direct: The implementation here uses a hybrid * direct/indirect method. If we had more data registers, * then we could do better. If XAA supported a trigger write * address, the code would be simpler. * Color8x8PatternFill: Apparently, an 8x8 color brush cannot take an 8x8 * pattern from frame buffer memory. * ImageWrites: Same as CPUToScreenColorExpandFill * */ /* Driver data structures */ #include "radeon.h" #include "radeon_macros.h" #include "radeon_probe.h" #include "radeon_reg.h" #include "radeon_version.h" #ifdef XF86DRI #define _XF86DRI_SERVER_ #include "radeon_dri.h" #include "radeon_common.h" #include "radeon_sarea.h" #endif /* Line support */ #include "miline.h" /* X and server generic header files */ #include "xf86.h" static struct { int rop; int pattern; } RADEON_ROP[] = { { RADEON_ROP3_ZERO, RADEON_ROP3_ZERO }, /* GXclear */ { RADEON_ROP3_DSa, RADEON_ROP3_DPa }, /* Gxand */ { RADEON_ROP3_SDna, RADEON_ROP3_PDna }, /* GXandReverse */ { RADEON_ROP3_S, RADEON_ROP3_P }, /* GXcopy */ { RADEON_ROP3_DSna, RADEON_ROP3_DPna }, /* GXandInverted */ { RADEON_ROP3_D, RADEON_ROP3_D }, /* GXnoop */ { RADEON_ROP3_DSx, RADEON_ROP3_DPx }, /* GXxor */ { RADEON_ROP3_DSo, RADEON_ROP3_DPo }, /* GXor */ { RADEON_ROP3_DSon, RADEON_ROP3_DPon }, /* GXnor */ { RADEON_ROP3_DSxn, RADEON_ROP3_PDxn }, /* GXequiv */ { RADEON_ROP3_Dn, RADEON_ROP3_Dn }, /* GXinvert */ { RADEON_ROP3_SDno, RADEON_ROP3_PDno }, /* GXorReverse */ { RADEON_ROP3_Sn, RADEON_ROP3_Pn }, /* GXcopyInverted */ { RADEON_ROP3_DSno, RADEON_ROP3_DPno }, /* GXorInverted */ { RADEON_ROP3_DSan, RADEON_ROP3_DPan }, /* GXnand */ { RADEON_ROP3_ONE, RADEON_ROP3_ONE } /* GXset */ }; /* The FIFO has 64 slots.
