Neither. The bit that you quoted simply means that the alignment restrictions could be PCIe only, i.e., you might be able to get away with bad alignment with old PCI/AGP graphics cards. There is unlikely to be any way to switch it on/off.xenic wrote:@HansDoes that mean that kickstart/PCIGraphics.card needs to be fixed or would alignment issues be in the CFE firmware??EDIT: These alignment requirements could be more of a PCIe thing. In any case, correctly aligning transfers improves transfer speeds.
What needs to be done, is all code that reads-from/writes-to bitmaps in VRAM directly without being careful about alignment needs to be fixed. Such code could be in the graphics libraries, BOOPSI gadgets, or even in apps/games.
