|
Experimental - Scanline color expand - GX2
|
|
|
|
9/21/01 KJB
|
|
Ver 1.6.14
|
|
ModeInit - cr3a for MX/GX2, don't clear reserved bit 0x40 (revert change).
|

Back out previous cr3a patch for testing.
|
|
|
|
9/18/01 KJB
|
|
Ver 1.6.13
|
|
Option "xvideo" added. Add patch provided by Sven Menke
|

|
|
|
|
1/03/01 KJB
|
|
Ver 1.6.0
|
|
Revert ViRGE to pre-Xv changes. ViRGE DX still supports Xv, but changes
|
|
added for Xv and ViRGE caused problems with normal display.
|
|
|
|
11/27/00 KJB
|
|
Ver 1.5.0
|
|
Clean up, bump version for 4.0.2 submission.
|
|
CR3A, bit 0x40 (reserved) cleared for MX/GX2. Update man page.
|
|
|
|
11/24/00 KJB
|
|
Disable CPU to screen color expansion on GX2, causes lockups on GX2 with
|
|
'locate html' in an xterm. Add WaitCmd code to prevent accelerator and
|
|
reg command path activity at the same time on GX2.
|
|
XVideo fixes, left side clipping fixed for video windows extending off left
|
|
side of screen. Add horizontal filtering modes for 1-2x and >3x scaling.
|
|
|
|
11/7/00 KJB
|
|
Ver 1.4.0
|
|
Enable MX fixes, testing with accel BLT_BUG set is worse on GX2, so left
|
|
it out. BLT_BUG wasn't being enabled on ViRGE & VX because of case usage,
|
|
enabled now. Re-enable silken mouse for GX2. Add Render/fbPicture support.
|
|
Fix a few compiler warnings.
|
|
|
|
11/5/00 KJB
|
|
Continued work on GX2, much stabler now, but I think there is a lockup case
|
|
left if you enable pci_burst and pci_retry with accel. I still see screen
|
|
flashes with vertical bars once in a while, and the log reports a GEReset.
|
|
Added fbPicture (render) support, untested. XV code for GX2 is added,
|
|
but not working yet.
|
|
|
|
10/29/00 KJB
|
|
Much work on GX2, now SWCursor locks up but HWCursor is stable, go figure.
|
|
Loading Netscape a couple times with the mail window was enough to lock it
|
|
up twice in a row. Server was locked but not a box (PCI) lock. Also,
|
|
vertical barring still occurred a couple times, so HW cursor wasn't causing
|
|
that. Try blt_bug flag again for lock up case. And attach to debug server
|
|
and bt... Sleep now...
|
|
|
|
10/21/00 KJB
|
|
Ver 1.3.0
|
|
Depth 16 Xv support added. Testing on ViRGE DX. 1280x1024x24 is noisy, so
|
|
needs FIFO tuning.
|
|
|
|
9/27/00 KJB
|
|
Initial Xv support in depth 24.
|
|
|
|
9/10/00 KJB
|
|
Convert to FB. Add option "UseFB", default true. Added
|
|
VerticalRetraceWait timeout back as default. #if0 out the line accel
|
|
code in s3v_accel.c. The Subsequent...Bresenham line code causes a lockup
|
|
when used with fb. We didn't have any hardware accel in there anyway...
|
|
|
|
7/25/00 KJB
|
|
Started Xv additions.
|
|
|
|
6/26/00 KJB
|
|
GX2 seems to have an accel bug. I see the entire screen go solid color or
|
|
a wide stripe pattern for about 1 second. The S3VGEReset gets called twice,
|
|
and then everything is okay. Unless SilkenMouse is enabled... That seems to
|
|
get you a server lock instead. Short term is to disable SilkenMouse for GX2
|
|
only. SilkenMouse isn't really the problem of course, it just happens that if
|
|
we move the mouse during the 1 second engine lockup we appear more likely to
|
|
never recover.
|
|
|
|
6/23/00 KJB
|
|
Ver 1.2.0 - Fix console corruption on GX2 caused by reserved bit use in CR3A.
|
|
Fix GX2 noise on screen in hi-res depth 24 by increasing FIFO fill threshold.
|
|
|
|
6/12/00 KJB
|
|
Ver 1.1.0 - Add Init for SilkenMouse, add xf86SetBackingStore call, move
|
|
int10Symbols[] to remove warnings.
|
|
|
|
3/3/00 KJB
|
|
Ver 1.0.0 - S3VProbeDDC code for X -configure option added, add timeout to
|
|
WAITIDLE macro in s3v_macros.h, change ImageWriteFlags adding NO_GXCOPY.
|
|
Start of GX2 fixes, use CR regs for FIFO settings. Update copyrights.
|
|
|
|
2/11/00 KJB
|
|
Ver 0.11.0 - Add cfb16/24BresS to module symbols to remove warnings.
|
|
Fix viewport restore problem after EnterVT in 24 bpp.
|
|
Clean up log output, removing register dumps from normal console log.
|
|
|
|
6/26/99 KJB
|
|
Make the memory settings for fifo_conservative the default, 'fifo_conservative'
|
|
does nothing additional now. Patch includes DGA2 additions below, non-working.
|
|
Expected to be included in 3.9Pu.
|
|
|
|
Changes in 3.9Pt by others include additions for newer RAC support. Some reports
|
|
say multi-head works now with ViRGE.
|
|
|
|
6/17/99 KJB
|
|
Ver 0.9.0 - Prelim DGA2 support modeled after MGA.
|
|
|
|
5/28/99 KJB
|
|
Ver 0.8.0 - Changes to 3.9Po - Cleaned up debug register printing function, minor
|
|
changes to man page, remove S3V.sgml and add new s3virge.sgml in doc/sgml, also
|
|
remove README.S3V from doc directory.
|
|
|
|
|
|
4/5/99 KJB
|
|
3.9Ph - Ver 0.7.0 - Virge man page added, HW Cursor fixed, rename chipsets removing
|
|
slashes in the names.
|
|
|
|
03/27/99 KJB
|
|
Ver 0.6.0 - hwcursor additions, added s3v_hwcurs.c and Option "swcursor".
|
|
Default is hwcursor, Option "swcursor" will disable it.
|
|
|
|
Ver 0.5.0 - patch against 3.9Pf (seq 2615), fix depth 24 and Accel flags, sync pci_burst option to previous changes, remove s3v_comp.h and s3v_pio.c and merge as needed.
|
|
|
|
03/21/99 KJB
|
|
3.9Pf has Matt Grossman's Alpha changes.
|
|
For next patch - remove s3v_pio.c and s3v_comp.h. Include the EnableMMIO and
|
|
DisableMMIO functions from s3v_pio.c in s3v_driver.c.
|
|
|
|
03/02/99 KJB
|
|
3.9Pc - depth 24 doesn't work on my ViRGE DX. NoAccel doesn't start, accel does
|
|
but has blocky noise.
|
|
|
|
03/01/99 KJB
|
|
Macro change done, VGAIN/VGAOUT for register access, INREG/OUTREG for s3v_accel.c.
|
|
Added Mark Vojkovich's re-write of the accel code. It may only be clean for ViRGE DX
|
|
at the moment. x11perf showed a couple artifacts in 'move window via parent'.
|
|
In progress, attempt to call cfbScreenInit() functions after MapMem/EnterVT. Not
|
|
working yet. Version stamped 0.4.0.
|
|
|
|
02/22/99 KJB
|
|
Macro change coming to add Mark's accel update. VGAOUT for old stuff and MEMOUT
|
|
for new stuff? That way there's no confusion with the old INREG/OUTREG macros.
|
|
Or maybe just stick with INREG/OUTREG for new stuff.
|
|
|
|
01/30/99 KJB
|
|
Version stamp 0.3.0. Changed Chipset flags to use PCI IDs exclusively, also use
|
|
common/xf86PciInfo.h for PCI IDs rather than coding them in regs3v.h.
|
|
|
|
11/28/98 KJB
|
|
Bumped version stamp to 0.2, expect code in 3.9No. Cleaned up s3v.h and
|
|
s3v_driver.c by removing unused definition & code sections. Added
|
|
options set_mclk (from 3.3.2) and set_lcdclk (3.3.3 MX). Code support
|
|
from 3.3.3 for ViRGE GX2 and MX+ is included.
|
|
Disabled call to 32 bpp AccelInit to get -depth 24 -bpp 32 working again.
|
|
|
|
11/27/98 KJB
|
|
More 3.3.3 import.
|
|
New registers saved, CR40,CR45,SR8,(for MX) SR29,SR45,SR55,SR56,SR57.
|
|
Reviewed s3vdriver.h, rehs3v.h, newmmio.h, s3v_accel.c, s3v_driver.c.
|
|
Added ViRGE MX, MX+ & GX2 support. Re-synced parts of mode save and init
|
|
with 3.3.3 versions. Added timeout ability for WaitIdle() and friends.
|
|
Added chipnames and numbers to Chipsets struct.
|
|
|
|
11/26/98 KJB
|
|
Import additions from 3.3.3, newmmio.h, regs3v.h,
|
|
|
|
Trap fills disabled because they don't match cfb, pixmap cache & ImageWrite
|
|
working, fixed depth 8 color loss on VT switches, INREG & OUTREG modified to
|
|
use a single offset value instead of adding the base and offset together.
|
|
|
|
11/18/98 KJB
|
|
3.9Nn
|
|
Acceleration working for Bitblt, ScreenToScreenCopy, Color 8x8 Rect fills,
|
|
and Rect/Trap fills.
|
|
Trap fills do not support transparency, so that needs to be exported to XAA.
|
|
|
|
|
|
10/31/98 KJB
|
|
Working depth 8, discolored dep 16 but runs, dep 24 screen goes black,
|
|
C-A-Bkspc restores text console. At 3.9Nk tree level, module would not
|
|
load in Loader server. why? Static server tested.
|
|
|
|
10/29/98 KJB
|
|
ModeInit() needs work, options are heavily #if'd to try and get 8bpp
|
|
working.
|
|
|
|
10/16/98 KJB
|
|
General 4.0 architecture is setup. Presently at 3.9Nc level, if moved
|
|
to a newer tree you will need to add the resource handling functions from
|
|
Egbert (I haven't tackled that yet).
|
|
|
|
At the moment the ScreenInit() function is coded to return FALSE. On my
|
|
ViRGE DX card this version does not lock up, but it does destroy the
|
|
video mode. Make sure you have an external terminal or network connection
|
|
if you run it (or blindly do a restart from your main terminal). I make
|
|
no guarantees that it won't hard lock other versions of ViRGE.
|
|
|
|
I've left out the Alpha memory mapping, along with all option processing.
|
|
Those will need to be done once the driver is minimally working.
|
|
|
|
Note that everything in s3v_driver.c is MMIO only. There are a pair of
|
|
PIO functions in s3v_pio.c, but that is the only place. See notes below
|
|
about my ViRGE DX BIOS and why I needed to do this on my hardware.
|
|
|
|
Other stuff...
|
|
Some test stuff is assuming 8bpp, so 16 & 24 are broken.
|
|
On my hardware, I am presently trying to get the Save/Restore sequence to
|
|
recover the video mode. At the moment, when I run this driver, I get:
|
|
ScreenInit() runs to completion.
|
|
It returns FALSE, so the Server aborts.
|
|
LeaveVT() is called, and runs to completion.
|
|
The Server exits gracefully, but my monitor goes powersaver and the video
|
|
mode is not recovered.
|
|

Notes:
|
|
----------
|
|
|
|
/config/cf/xfree86.cf
|
|
|
|
have to add s3v to XF86CardDrivers for imake to make the
|
|
drivers/s3v Makefile.
|
|
|
|
To remake makefiles, after editing Imakefile, go to dir above drivers/s3v
|
|
and do a 'make Makefiles'.
|
|
|
|
For debug, make CDEBUGFLAGS='-g -DDEBUG', adding -DMetroLink enables
|
|
timeout for VerticalRetraceWait().
|
|
|
|
|
|
|
|
S3 ViRGE DX stuff:
|
|
|
|
Card seems to power up (or BIOS forces) with MMIO disabled. All flavors are
|
|
disabled, because CR53 comes up as 0. This may preclude using this card
|
|
as the second device in a multi-head situation although David D. says that
|
|
the new config. management stuff may help here.
