Krzysztof Heltfeff3882009-04-06 19:01:03 -070013 * I2C part copied from the i2c-voodoo3.c driver by:

15 * Philip Edelbrock <phil@netroedge.com>,

Krzysztof Helt8af1d502007-10-16 01:28:43 -070019 * Lots of the information here comes from the Daryll Strauss' Banshee
Linus Torvalds1da177e2005-04-16 15:20:36 -070020 * patches to the XF86 server, and the rest comes from the 3dfx
21 * Banshee specification. I'm very much indebted to Daryll for his
22 * work on the X server.
23 *
24 * Voodoo3 support was contributed Harold Oga. Lots of additions
25 * (proper acceleration, 24 bpp, hardware cursor) and bug fixes by Attila
26 * Kesmarki. Thanks guys!
27 *
28 * Voodoo1 and Voodoo2 support aren't relevant to this driver as they
29 * behave very differently from the Voodoo3/4/5. For anyone wanting to
30 * use frame buffer on the Voodoo1/2, see the sstfb driver (which is
31 * located at http://www.sourceforge.net/projects/sstfb).

Linus Torvalds1da177e2005-04-16 15:20:36 -070033 * While I _am_ grateful to 3Dfx for releasing the specs for Banshee,
34 * I do wish the next version is a bit more complete. Without the XF86
35 * patches I couldn't have gotten even this far... for instance, the
36 * extensions to the VGA register set go completely unmentioned in the
37 * spec! Also, lots of references are made to the 'SST core', but no
38 * spec is publicly available, AFAIK.
39 *
40 * The structure of this driver comes pretty much from the Permedia
41 * driver by Ilario Nardinocchi, which in turn is based on skeletonfb.

Linus Torvalds1da177e2005-04-16 15:20:36 -070043 * TODO:
Linus Torvalds1da177e2005-04-16 15:20:36 -070044 * - multihead support (basically need to support an array of fb_infos)
45 * - support other architectures (PPC, Alpha); does the fact that the VGA
46 * core can be accessed only thru I/O (not memory mapped) complicate
47 * things?
48 *
49 * Version history:
50 *
Krzysztof Helt3cbe9cf2007-10-16 01:29:28 -070051 * 0.1.4 (released 2002-05-28) ported over to new fbdev api by James Simmons
Linus Torvalds1da177e2005-04-16 15:20:36 -070052 *
Krzysztof Helt3cbe9cf2007-10-16 01:29:28 -070053 * 0.1.3 (released 1999-11-02) added Attila's panning support, code
54 * reorg, hwcursor address page size alignment
André Goddard Rosaaf901ca2009-11-14 13:09:05 -020055 * (for mmapping both frame buffer and regs),
Krzysztof Helt3cbe9cf2007-10-16 01:29:28 -070056 * and my changes to get rid of hardcoded
57 * VGA i/o register locations (uses PCI
58 * configuration info now)
59 * 0.1.2 (released 1999-10-19) added Attila Kesmarki's bug fixes and
60 * improvements
61 * 0.1.1 (released 1999-10-07) added Voodoo3 support by Harold Oga.
62 * 0.1.0 (released 1999-10-06) initial version
