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. + + + +TODO items +---------- +1/30/03 General option "videoram" is ignored by the virge driver. + (Meelis Roos) +3/24/02 Xv reported to not work as secondary in Xinerama multihead. + (xav on irc) +3/24/02 DPMS doesn't fully disable the screen.
