2: * UAE - The U*nix Amiga Emulator
3: *
4: * Picasso96 Support Module
5: *
6: * Copyright 1997 Brian King <[email protected], [email protected]>
7: *
8: * Theory of operation:
9: * On the Amiga side, a Picasso card consists mainly of a memory area that
10: * contains the frame buffer. On the UAE side, we allocate a block of memory
11: * that will hold the frame buffer. This block is in normal memory, it is
12: * never directly on the graphics card. All graphics operations, which are
13: * mainly reads and writes into this block and a few basic operations like
14: * filling a rectangle, operate on this block of memory.
15: * Since the memory is not on the graphics card, some work must be done to
16: * synchronize the display with the data in the Picasso frame buffer. There
17: * are various ways to do this. One possibility is to allocate a second
18: * buffer of the same size, and perform all write operations twice. Since
19: * we never read from the second buffer, it can actually be placed in video
20: * memory. The X11 driver could be made to use the Picasso frame buffer as
21: * the data buffer of an XImage, which could then be XPutImage()d from time
22: * to time. Another possibility is to translate all Picasso accesses into
23: * Xlib (or GDI, or whatever your graphics system is) calls. This possibility
24: * is a bit tricky, since there is a risk of generating very many single pixel
25: * accesses which may be rather slow.
26: *
27: * TODO:
28: * - add panning capability
1.1.1.3 root 29: * - we want to add a manual switch to override SetSwitch for hardware banging
30: * programs started from a Picasso workbench.
