207 -------------------------------------------
213 - ddfstrt and ddfstop are best aligned to 64 pixels.
214 - the chipset needs 64 + 4 horizontal pixels after the DMA start before
218 - the display DMA always fetches 64 pixels at a time (fmode = 3).
219 - ddfstop is ddfstrt+#pixels - 64.
220 - diwstop_h = diwstrt_h + xres + 1. Because of the additional 1 this can
222 - hscroll simply adds a delay to the display output. Smooth horizontal
225 - if ddfstrt < 192, the sprite DMA cycles are all stolen by the bitplane
226 DMA, so it's best to make the DMA start as late as possible.
227 - you really don't want to make ddfstrt < 128, since this will steal DMA
228 cycles from the other DMA channels (audio, floppy and Chip RAM refresh).
229 - I make diwstop_h and diwstop_v as large as possible.
232 --------------------
234 - all values are SHRES pixel (35ns)
237 ------------------ ---------------- -----------------
239 -------------#------+-----+------#------+-----+------#------+-----+------
244 - chipset needs 4 pixels before the first pixel is output
245 - ddfstrt must be aligned to fetchstart (table 1)
246 - chipset needs also prefetch (table 2) to get first pixel data, so
247 ddfstrt = ((diwstrt_h - 4) & -fetchstart) - prefetch
248 - for horizontal panning decrease diwstrt_h
249 - the length of a fetchline must be aligned to fetchsize (table 3)
250 - if fetchstart is smaller than fetchsize, then ddfstrt can a little bit
251 moved to optimize use of dma (useful for OCS/ECS overscan displays)
252 - ddfstop is ddfstrt + ddfsize - fetchsize
253 - If C= didn't change anything for AGA, then at following positions the
254 dma bus is already used:
255 ddfstrt < 48 -> memory refresh
256 < 96 -> disk dma
257 < 160 -> audio dma
258 < 192 -> sprite 0 dma
259 < 416 -> sprite dma (32 per sprite)
260 - in accordance with the hardware reference manual a hardware stop is at
263 DMA priorities
264 --------------
266 Since there are limits on the earliest start value for display DMA and the
270 - if you want to start display DMA too early, you lose the ability to
271 do smooth horizontal panning (xpanstep 1 -> 64).
272 - if you want to go even further, you lose the hardware cursor too.
