8af1d50f | 13 | * Lots of the information here comes from the Daryll Strauss' Banshee |
1da177e4 LT |
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. | |
17 | * | |
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! | |
21 | * | |
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. | |
33 | * | |
34 | * The structure of this driver comes pretty much from the Permedia | |
35 | * driver by Ilario Nardinocchi, which in turn is based on skeletonfb. | |

1da177e4 | 37 | * TODO: |
1da177e4 LT |
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 | |
41 | * things? | |
42 | * | |
43 | * Version history: | |
44 | * | |
3cbe9cff | 45 | * 0.1.4 (released 2002-05-28) ported over to new fbdev api by James Simmons |
1da177e4 | 46 | * |
3cbe9cff KH |
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 | |
54 | * improvements | |
55 | * 0.1.1 (released 1999-10-07) added Voodoo3 support by Harold Oga. | |
56 | * 0.1.0 (released 1999-10-06) initial version | |

1111 | * and are stored on chip for use for the next 8 scanlines. | |
1112 | * This reduces the number of times for access to draw the | |
1113 | * cursor for each screen refresh. | |
1114 | * Each pattern is a bitmap of 64 bit wide and 64 bit high | |
90b0f085 | 1115 | * (total of 8192 bits or 1024 bytes). The two patterns are |
1da177e4 LT |
1116 | * stored in such a way that pattern 0 always resides in the |
1117 | * lower half (least significant 64 bits) of a 128 bit word | |
1118 | * and pattern 1 the upper half. If you examine the data of | |
1119 | * the cursor image the graphics card uses then from the | |
1120 | * begining you see line one of pattern 0, line one of | |
1121 | * pattern 1, line two of pattern 0, line two of pattern 1, | |
1122 | * etc etc. The linear stride for the cursor is always 16 bytes | |
1123 | * (128 bits) which is the maximum cursor width times two for | |
1124 | * the two monochrome patterns. | |
