/* * by Daniel Mantione * <daniel.mantione@freepascal.org> * * * ATI Mach64 CT clock synthesis description. * * All clocks on the Mach64 can be calculated using the same principle: * * XTALIN * x * FB_DIV * CLK = ---------------------- * PLL_REF_DIV * POST_DIV * * XTALIN is a fixed speed clock. Common speeds are 14.31 MHz and 29.50 MHz. * PLL_REF_DIV can be set by the user, but is the same for all clocks. * FB_DIV can be set by the user for each clock individually, it should be set * between 128 and 255, the chip will generate a bad clock signal for too low * values. * x depends on the type of clock; usually it is 2, but for the MCLK it can also * be set to 4. * POST_DIV can be set by the user for each clock individually, Possible values * are 1,2,4,8 and for some clocks other values are available too. * CLK is of course the clock speed that is generated. * * The Mach64 has these clocks: * * MCLK The clock rate of the chip * XCLK The clock rate of the on-chip memory * VCLK0 First pixel clock of first CRT controller * VCLK1 Second pixel clock of first CRT controller * VCLK2 Third pixel clock of first CRT controller * VCLK3 Fourth pixel clock of first CRT controller * VCLK Selected pixel clock, one of VCLK0, VCLK1, VCLK2, VCLK3 * V2CLK Pixel clock of the second CRT controller. * SCLK Multi-purpose clock * * - MCLK and XCLK use the same FB_DIV * - VCLK0 .. VCLK3 use the same FB_DIV * - V2CLK is needed when the second CRTC is used (can be used for dualhead); * i.e. CRT monitor connected to laptop has different resolution than built * in LCD monitor. * - SCLK is not available on all cards; it is know to exist on the Rage LT-PRO, * Rage XL and Rage Mobility. It is know not to exist on the Mach64 VT. * - V2CLK is not available on all cards, most likely only the Rage LT-PRO, * the Rage XL and the Rage Mobility * * SCLK can be used to: * - Clock the chip instead of MCLK * - Replace XTALIN with a user defined frequency * - Generate the pixel clock for the LCD monitor (instead of VCLK)
*/
/* * It can be quite hard to calculate XCLK and MCLK if they don't run at the * same frequency. Luckily, until now all cards that need asynchrone clock * speeds seem to have SCLK. * So this driver uses SCLK to clock the chip and XCLK to clock the memory.
*/
/* * PLL programming (Mach64 CT family) * * * This procedure sets the display fifo. The display fifo is a buffer that * contains data read from the video memory that waits to be processed by * the CRT controller. * * On the more modern Mach64 variants, the chip doesn't calculate the * interval after which the display fifo has to be reloaded from memory * automatically, the driver has to do it instead.
