Maybe it will be fixed * in a subsequent hardware revision. * The problem is that the alpha plane will only work (that is, become * visible) if alpha_plane_tl is set to top:=0 and left:=0. * Also, if alpha_plane_br does not match panel dimensions, the alpha * plane will be displayed tilled in the "first" row, with corruption on * on all odd columns. * Since setting the alpha fb_address works, to implement an argb cursor * using the alpha plane, with the current hardware bugs, it would be * required to: * o allocate an offscreen area of pSmi->lcdWidth * pSmi->lcdHeight * 2 * o set statically tl/tr to 0,0,pSmi->lcdWidth-1,pSmi->lcdHeight-1 * o use alpha format 3 (argb 4:4:4:4), or alternatively format 1 * (rgb 5:6:5), and in the last case, a global 50% alpha is the * best bet, and for the argb cursors being used at the time of this * writing, they look correct, while 100% opaque looks wrong. * o when positioning the pointer, first erase it from the offscreen * area, then repaint it at the proper offset in the alpha offscreen * area. * .... argb software cursor works way better * (There are some other alternatives, like using 8 bits indexed mode, * but when using a global alpha value, instead of per pixel, most argb * cursors will not look correctly, regardless of the alpha value, that * should be from 50 to 100% transparency). * But still there would be the problem of memory requiring a 128 bit * alignment, what would require either moving the image in the memory, * and/or some trick with the vsync pixel panning. * * Until the alpha layer is corrected in some newer revision (or removed?), * it could be used as something like an alternate crt, that happens to be * on top of the panel (and has 16 transparency levels). */ #define SMI_CURSOR_ALPHA_PLANE 0 /******************************************************************************/ /* S T R U C T U R E S */ /******************************************************************************/ /* Driver data structure; this should contain all needed info for a mode */ typedef struct { CARD16 mode; CARD8 SR17, SR18; CARD8 SR20, SR21, SR22, SR23, SR24; CARD8 SR30, SR31, SR32, SR34; CARD8 SR40, SR41, SR42, SR43, SR44, SR45, SR48, SR49, SR4A, SR4B, SR4C; CARD8 SR50, SR51, SR52, SR53, SR54, SR55, SR56, SR57, SR5A; CARD8 SR66, SR68, SR69, SR6A, SR6B, SR6C, SR6D, SR6E, SR6F; CARD8 SR81, SRA0; CARD8 CR30, CR33, CR33_2, CR3A; CARD8 CR40[14], CR40_2[14]; CARD8 CR90[15], CR9F, CR9F_2; CARD8 CRA0[14]; CARD8 smiDACMask, smiDacRegs[256][3]; CARD8 smiFont[8192]; CARD32 DPR10, DPR1C, DPR20, DPR24, DPR28, DPR2C, DPR30, DPR3C, DPR40, DPR44; CARD32 VPR00, VPR0C, VPR10; CARD32 CPR00; CARD32 FPR00_, FPR0C_, FPR10_; } SMIRegRec, *SMIRegPtr; /* Global PDEV structure. */ typedef struct { int Bpp; /* Bytes per pixel */ int MCLK; /* Memory Clock */ int MXCLK; /* MSOC Clock for local sdram */ ClockRange clockRange; /* Allowed pixel clock range */ CloseScreenProcPtr CloseScreen; /* Pointer used to save wrapped CloseScreen function */ I2CBusPtr I2C; /* Pointer into I2C module */ xf86Int10InfoPtr pInt10; /* Pointer to INT10 module */ vbeInfoPtr pVbe; /* Pointer to VBE module */ pciVideoPtr PciInfo; /* PCI info vars */ #ifndef XSERVER_LIBPCIACCESS PCITAG PciTag; #endif int Chipset; /* Chip info, set using PCI above */ int ChipRev; OptionInfoPtr Options; Bool Dualhead; /* Don't attempt to program a video mode.
