## 1. Change Log

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 :-(
