Hi, in my set-up (Amiga2000, PicassoII graphics adapter), there is an issue with the display. In low resolution modes (640x460), there are some flickering pixels. Many more of them occur, if I switch to higher resolution modes (1024x768). Scrolling really results in a mess on the display in these modes.
When looking at the code of clgenfb, I found that the value for the display memory clock MCLK is calculated depending on the value of the video pixel clock VCLK. According to the video adapter chip (Cirrus Logic GD5426) manual, MCLK should be set depending on video memory speed, i. e. regardless of VCLK. If MCLK is calculated depending on VCLK, the memory interface can be overclocked for higher resolution modes. Is someone who used to work on clgenfb code still around? I would like to discuss this issue with him and try to come up with code that avoids the display problems with my Picasso board.
