s3fb: fix Virge/VX

2011-12-21T02:25:21+00:00

Add memory size detection for Virge/VX and small delay in mode setting (same
as in X.org driver) to fix blank screen problem.

Also adjust DTPC position to fix garbled screen in some modes (tested that
this adjustment does not break other cards - at least Trio32, Trio64V+,
Trio64V2/DX, Virge, Virge/DX).

Tested on ELSA Winner 2000AVI/3D.

s3fb: use display information in info not in var for panning

2011-06-15T06:03:03+00:00

We must not use any information in the passed var besides xoffset,
yoffset and vmode as otherwise applications might abuse it.

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.
