1. Change Log

1998.10.13:

• Fixed a bug that would cause the server to crash when it tried to enable or disable the screen saver while at a VT (Erik Nygren)

1997.01.30:

• Added probing for MemBase and IOBase on Diamond Viper PCI cards (Karl Anders Øygard)
• Added support for DPMI screen saving (Karl Anders Øygard)

1996.03.31:

• Added support for the XFree86-DGA extension (Erik Nygren)

1995.05.24:

• Added p9000frect.c: Accelerated solid rectangle fills at 8/16bpp (Henrik Harmsen)
• Added stipple fills to p9000frect.c, and a stub for tile fills when p9000ImageFill is fixed (Chris Mason)
• Added p9000pntwin.c: Accelerated paint window at 8/16/32bpp (Henrik Harmsen)
• Added p9000gc16.c and p9000gc32.c for the higher bpp drawing functions (Henrik Harmsen)
• Additions to p9000im.c: p9000Image[Op]Stipple. And p9000ImageFill. Currently, there are small problems with ImageFill, and it is not being used. (Chris Mason)
• Added p9000PixAlu and p9000PixOpAlu. miniterm->alu translation for pixel1 opaque and transparent operations. (Chris Mason)
• Added p9000text.c: Non-cached poly text and image text functions. Image text functions are not used because they are too slow :( (Chris Mason)

1995.05.21:

• Fixed p9000init.c to properly deal with the vram_128 option. This should allow the driver to work properly with all Viper's with 1 MB of memory. (Erik Nygren)

1995.01.29:

• Updated P9000.sgml to mention using Robin's scanpci rather than PCIDUMP.EXE.

1995.01.15:

• Fixed problem with line capping in accelerated line drawing. (Chris Mason)
• Fixed p9000QuadAlu[GXset] to be ~0 rather than 1. (Erik Nygren)

1995.01.14:

• Clocks line is no longer used in XF86Config file. Operation should now be consistent with the operation of the other servers which use programmable clocks. (Erik Nygren)
• Users with 1MB cards can now explicitly specify videoRam in the XF86Config file when autoprobing fails. The new vram_128 option may also be used to force the detection of 128Kx8 SIMM's. (Erik Nygren)
• Added p9000line.c and p9000seg.c for accelerated line drawing code using the p9000 quad/clipping engine. Blazingly fast for 1 clipping rectangle, could be made faster for multiple clipping regions by using software clipping. There is still a bug which causes xtest to report Cap style incorrect for thin line and CapNotLast for the XDrawLines tests but not for the XDrawLine or XDrawSegments tests [fixed in 1995.01.15 patch]. (Chris Mason)
• Changed p9000blt.c, and p9000win.c to wait for the quad/blit engine to be free. Before a quad/blit, check SR_ISSUE_QBN, then blit, then when all blits are done, do a p9000QBNotBusy. (Chris Mason)
• Changed p9000init.c to clear the screen using the quad meta coord drawing mode. Appears the rect mode does not update the CINDEX register correctly. Changed the color to 1 (black) from 0. (Chris)
• Added p9000QuadAlu. When drawing a quad, the p9000 equivalent to X's source is the foreground mask. When bliting/pixel8ing/pixel1ing, it is the p9000 source mask and the p9000alu lookup table should be used. (Chris Mason)
• Added some more registers to p9000reg.h. (Chris Mason)

1994.09.20:

• Fixed problem which prevented 16 bpp modes from working (Erik Nygren)

1994.09.16:

• Added screen blanking support for 16 bpp and 32 bpp modes. Screen blanking now powers down the RAMDAC rather than just changing the planemask. (Chris Mason, Erik Nygren)
• Fixed more problems caused by switch to XF86Config (Erik Nygren)
• Possible fix to maxclock for Orchid P9000 (Harry Langenbacher, Erik Nygren)

1994.09.15:

• Now almost always works with XF86Config changes (Erik Nygren)
• Cursor code looks at VTSema before writing to RAMDAC. This had been causing the x11perf server crash (Erik Nygren)

1994.09.08:

• Fixed problem with xdm and restarting the server (Erik Nygren)
• Fixed and enabled ImageRead in CopyArea (Chris Mason)
• Made informational comments conform to standard :-) (Erik Nygren)

1994.09.05:

• Fixed BIOS probe for Viper PCI (Bob Hollinger)
• Fixes to Orchid P9000 support (Harry Langenbacher)
• Changing of datatypes in clock code (Harry Langenbacher)
• Fixed clock and misc reg restoration so now works fine with svgalib (Chris Mason, Harry, Erik)

1994.08.29:

• Increased number of memory regions in xf86_OSlib.h from 2 to 3 as needed by the Viper PCI (Erik Nygren)
• Changed method of short pauses in p9000vga.c to outb(0x80,0) (Erik)
• Rewrote routines to determine sysconfig from horizontal resolution. Also added check for valid hres to probe. (Erik Nygren)
• Added MoveWindow acceleration for all depths. Opaque move even looks nice at 32bpp now! (Chris Mason)
• Minor fixes to acceleration. Acceleration is now enabled by default (Chris Mason)
• Added "noaccel" option (Erik Nygren)
• Added some fixes for Viper PCI (Matt Thomas)

1994.07.21:

• Preliminary Viper PCI support - totally untested so disabled (Erik Nygren)
• Preliminary Orchid P9000 support - incomplete and totally untested so disabled (Erik Nygren)
• Preliminary accelerated support - incomplete and not fully tested so disabled (Erik Nygren and Chris Mason)

1994.07.08:

• 16 and 32 bpp TrueColor support (Erik Nygren)
• Color restoration hopefully fixed (Erik Nygren)
• Changes to how "Modes" line in Xconfig is processed
• Removed banking support :-(
