I still see screen 100 1.1 mrg flashes with vertical bars once in a while, and the log reports a GEReset. 101 1.1 mrg Added fbPicture (render) support, untested. XV code for GX2 is added, 102 1.1 mrg but not working yet. 103 1.1 mrg 104 1.1 mrg 10/29/00 KJB 105 1.1 mrg Much work on GX2, now SWCursor locks up but HWCursor is stable, go figure. 106 1.1 mrg Loading Netscape a couple times with the mail window was enough to lock it 107 1.1 mrg up twice in a row. Server was locked but not a box (PCI) lock. Also, 108 1.1 mrg vertical barring still occurred a couple times, so HW cursor wasn't causing 109 1.1 mrg that. Try blt_bug flag again for lock up case. And attach to debug server 110 1.1 mrg and bt... Sleep now... 111 1.1 mrg 112 1.1 mrg 10/21/00 KJB 113 1.1 mrg Ver 1.3.0 114 1.1 mrg Depth 16 Xv support added. Testing on ViRGE DX. 1280x1024x24 is noisy, so 115 1.1 mrg needs FIFO tuning. 116 1.1 mrg 117 1.1 mrg 9/27/00 KJB 118 1.1 mrg Initial Xv support in depth 24. 119 1.1 mrg 120 1.1 mrg 9/10/00 KJB 121 1.1 mrg Convert to FB. Add option "UseFB", default true. Added 122 1.1 mrg VerticalRetraceWait timeout back as default. #if0 out the line accel 123 1.1 mrg code in s3v_accel.c. The Subsequent...Bresenham line code causes a lockup 124 1.1 mrg when used with fb. We didn't have any hardware accel in there anyway... 125 1.1 mrg 126 1.1 mrg 7/25/00 KJB 127 1.1 mrg Started Xv additions. 128 1.1 mrg 129 1.1 mrg 6/26/00 KJB 130 1.1 mrg GX2 seems to have an accel bug. I see the entire screen go solid color or 131 1.1 mrg a wide stripe pattern for about 1 second. The S3VGEReset gets called twice, 132 1.1 mrg and then everything is okay. Unless SilkenMouse is enabled... That seems to 133 1.1 mrg get you a server lock instead. Short term is to disable SilkenMouse for GX2 134 1.1 mrg only. SilkenMouse isn't really the problem of course, it just happens that if 135 1.1 mrg we move the mouse during the 1 second engine lockup we appear more likely to 136 1.1 mrg never recover. 137 1.1 mrg 138 1.1 mrg 6/23/00 KJB 139 1.1 mrg Ver 1.2.0 - Fix console corruption on GX2 caused by reserved bit use in CR3A. 140 1.1 mrg Fix GX2 noise on screen in hi-res depth 24 by increasing FIFO fill threshold. 141 1.1 mrg 142 1.1 mrg 6/12/00 KJB 143 1.1 mrg Ver 1.1.0 - Add Init for SilkenMouse, add xf86SetBackingStore call, move 144 1.1 mrg int10Symbols[] to remove warnings. 145 1.1 mrg 146 1.1 mrg 3/3/00 KJB 147 1.1 mrg Ver 1.0.0 - S3VProbeDDC code for X -configure option added, add timeout to 148 1.1 mrg WAITIDLE macro in s3v_macros.h, change ImageWriteFlags adding NO_GXCOPY. 149 1.1 mrg Start of GX2 fixes, use CR regs for FIFO settings. Update copyrights. 150 1.1 mrg 151 1.1 mrg 2/11/00 KJB 152 1.1 mrg Ver 0.11.0 - Add cfb16/24BresS to module symbols to remove warnings. 153 1.1 mrg Fix viewport restore problem after EnterVT in 24 bpp. 154 1.1 mrg Clean up log output, removing register dumps from normal console log. 155 1.1 mrg 156 1.1 mrg 6/26/99 KJB 157 1.1 mrg Make the memory settings for fifo_conservative the default, 'fifo_conservative' 158 1.1 mrg does nothing additional now.

NoAccel doesn't start, accel does 190 1.1 mrg but has blocky noise. 191 1.1 mrg 192 1.1 mrg 03/01/99 KJB 193 1.1 mrg Macro change done, VGAIN/VGAOUT for register access, INREG/OUTREG for s3v_accel.c. 194 1.1 mrg Added Mark Vojkovich's re-write of the accel code. It may only be clean for ViRGE DX 195 1.1 mrg at the moment. x11perf showed a couple artifacts in 'move window via parent'. 196 1.1 mrg In progress, attempt to call cfbScreenInit() functions after MapMem/EnterVT. Not 197 1.1 mrg working yet. Version stamped 0.4.0. 198 1.1 mrg 199 1.1 mrg 02/22/99 KJB 200 1.1 mrg Macro change coming to add Mark's accel update. VGAOUT for old stuff and MEMOUT 201 1.1 mrg for new stuff? That way there's no confusion with the old INREG/OUTREG macros. 202 1.1 mrg Or maybe just stick with INREG/OUTREG for new stuff. 203 1.1 mrg 204 1.1 mrg 01/30/99 KJB 205 1.1 mrg Version stamp 0.3.0.

Presently at 3.9Nc level, if moved 248 1.1 mrg to a newer tree you will need to add the resource handling functions from 249 1.1 mrg Egbert (I haven't tackled that yet). 250 1.1 mrg 251 1.1 mrg At the moment the ScreenInit() function is coded to return FALSE. On my 252 1.1 mrg ViRGE DX card this version does not lock up, but it does destroy the 253 1.1 mrg video mode. Make sure you have an external terminal or network connection 254 1.1 mrg if you run it (or blindly do a restart from your main terminal). I make 255 1.1 mrg no guarantees that it won't hard lock other versions of ViRGE. 256 1.1 mrg 257 1.1 mrg I've left out the Alpha memory mapping, along with all option processing. 258 1.1 mrg Those will need to be done once the driver is minimally working. 259 1.1 mrg 260 1.1 mrg Note that everything in s3v_driver.c is MMIO only.
