13 * Lots of the information here comes from the Daryll Strauss' Banshee
14 * patches to the XF86 server, and the rest comes from the 3dfx
15 * Banshee specification. I'm very much indebted to Daryll for his
16 * work on the X server.
18 * Voodoo3 support was contributed Harold Oga. Lots of additions
19 * (proper acceleration, 24 bpp, hardware cursor) and bug fixes by Attila
20 * Kesmarki. Thanks guys!
22 * Voodoo1 and Voodoo2 support aren't relevant to this driver as they
23 * behave very differently from the Voodoo3/4/5. For anyone wanting to
24 * use frame buffer on the Voodoo1/2, see the sstfb driver (which is
25 * located at http://www.sourceforge.net/projects/sstfb).
27 * While I _am_ grateful to 3Dfx for releasing the specs for Banshee,
28 * I do wish the next version is a bit more complete. Without the XF86
29 * patches I couldn't have gotten even this far... for instance, the
30 * extensions to the VGA register set go completely unmentioned in the
31 * spec! Also, lots of references are made to the 'SST core', but no
32 * spec is publicly available, AFAIK.
34 * The structure of this driver comes pretty much from the Permedia
35 * driver by Ilario Nardinocchi, which in turn is based on skeletonfb.
38 * - multihead support (basically need to support an array of fb_infos)
39 * - support other architectures (PPC, Alpha); does the fact that the VGA
40 * core can be accessed only thru I/O (not memory mapped) complicate
45 * 0.1.4 (released 2002-05-28) ported over to new fbdev api by James Simmons
47 * 0.1.3 (released 1999-11-02) added Attila's panning support, code
48 * reorg, hwcursor address page size alignment
49 * (for mmaping both frame buffer and regs),
50 * and my changes to get rid of hardcoded
51 * VGA i/o register locations (uses PCI
52 * configuration info now)
53 * 0.1.2 (released 1999-10-19) added Attila Kesmarki's bug fixes and
55 * 0.1.1 (released 1999-10-07) added Voodoo3 support by Harold Oga.
56 * 0.1.0 (released 1999-10-06) initial version

1093 * Voodoo 3 and above cards use 2 monochrome cursor patterns.
1094 * The reason is so the card can fetch 8 words at a time
1095 * and are stored on chip for use for the next 8 scanlines.
1096 * This reduces the number of times for access to draw the
1097 * cursor for each screen refresh.
1098 * Each pattern is a bitmap of 64 bit wide and 64 bit high
1099 * (total of 8192 bits or 1024 Kbytes). The two patterns are
1100 * stored in such a way that pattern 0 always resides in the
1101 * lower half (least significant 64 bits) of a 128 bit word
1102 * and pattern 1 the upper half. If you examine the data of
1103 * the cursor image the graphics card uses then from the
1104 * begining you see line one of pattern 0, line one of
1105 * pattern 1, line two of pattern 0, line two of pattern 1,
1106 * etc etc. The linear stride for the cursor is always 16 bytes
1107 * (128 bits) which is the maximum cursor width times two for
1108 * the two monochrome patterns.
