s3fb: add DDC support

2011-04-19T06:50:53+00:00

Add I2C support for the DDC bus and also default mode initialization by
reading monitor EDID to the s3fb driver.

Tested on Trio64V+ (2 cards), Trio64V2/DX, Virge (3 cards),
Virge/DX (3 cards), Virge/GX2, Trio3D/2X (4 cards), Trio3D.

Will probably not work on Trio32 - my 2 cards have DDC support in BIOS that
looks different from the other cards but the DDC pins on the VGA connector
are not connected.

s3fb: fix Virge/GX2

2011-03-31T04:48:58+00:00

Fix Virge/GX2 support in s3fb:
- fix IDs: 86C357 is GX2, 86C359 is GX2+, 86C356 probably does not exist
- add memory size detection
- drive it the same way as Trio3D/2X

The original IDs most likely came from S3 website which claims that:
- 356 is Virge/GX2 with ID=8A10, driver included in Windows 2K, XP
- 357 is Virge/GX2+ with ID=8A11, driver included in Windows ME
- 359 is Virge/GX2+ with ID=8A12, driver included in Windows ME
but:
- google search for 86C356 only reveals references to Trio3D (probably
because of a typo - Trio3D is 86C365)
- my card is clearly marked as 86C357, Virge/GX2 and has ID=8A10
- there is no driver for IDs 8A11 and 8A12 in Windows ME
- there is a driver for ID 8A10 in Windows ME that says it's GX2 (357)

Tested with #9 Reality 334 (86C357 Virge/GX2, ID=0x8A10).

s3fb: use new start address register

2011-03-22T06:50:00+00:00

Use "new" start address register 0x69 (bits 16-20) instead of "old" 0x31
(bits 16-17) and 0x51 (bits 18-19). This is needed for panning to work
correctly on Trio3D/2X cards (and does no harm on other ones).

s3fb: enable DTPC

2011-03-22T06:49:56+00:00

Enable Data Transfer Position Control (DTPC). This is needed at least on
Virge/DX to correctly display at higher pixclocks.

s3fb: fix 15/16bpp modes with over 115MHz pixclocks on 86C365 Trio3D

2011-03-22T06:49:53+00:00

Enable pixel multiplexing in 15/16bpp modes when pixclock is over 115MHz
on Trio3D (86C365) cards to fix artifacts on the left side of screen.
