+ * depth
+ * - fixed a problem related to color/depth/alpha buffer clears
+ * - fixed a problem when clearing buffer for a context with the
+ * alpha buffer
+ * - fixed a problem in the fxTMReloadSubMipMapLevel() function,
+ * I have forget a "break;" (thanks to Joe Waters for the bug report)
+ * - fixed a problem in the color format for the in window
+ * rendering hack
+ * - written the fxDDReadRGBAPixels function

+ * (thanks to Ben "Ctrl-Alt-Delete" and the Raul Alonso's ssystem)
+ * - fixed a small bug in the Rune's pixel-span optimization
+ * - fixed a problem with GL_CCW (thanks to Curt Olson for and example
+ * of the problem)
+ * - grVertex setup code is now ready for the internal thread support
+ * - fixed a no used optimization with clipped vertices in
+ * grVertex setup code
+ * - fixed a problem in the GL_LIGHT_MODEL_TWO_SIDE support (thanks
+ * to Patrick H. Madden for a complete example of the bug)
+ *
+ * Rune Hasvold (runeh@ifi.uio.no)
+ * - highly optimized the driver functions for writing pixel
+ * span (2-3 times faster !)
+ *
+ * Axel W. Volley (volley@acm.org) Krauss-Maffei Wehrtechnik
+ * - written the fxDDReadDepthSpanFloat() and fxDDReadDepthSpanInt()

+ * to save same driver call and state change for not very
+ * well written applications

+ * - vertex snap is not longer used for the Voodoo2 (FX_V2
+ * must be defined)
+ * - done a lot of cleanup in the fxsetup.c file
+ * - now the partial support for the Multitexture extension
+ * works with GLQuake for windows

+ * Multitexture extension
+ * - written a workaround in fxBestResolution() in order to solve a
+ * problem with bzflag (it asks for 1x1 window !)
+ * - changed the fxBestResolution() behavior. It now returns the larger
+ * screen resolution supported by the hardware (instead of 640x480)
+ * when it is unable to find an appropriate resolution that is large
+ * enough for the requested size
+ * - the driver is now able to use also the texture memory attached to
+ * second TMU
+ * - the texture memory manager is now able to work with two TMUs and
+ * store texture maps in the memory attached to TMU0, TMU1 or to split
+ * the mimpmap levels across TMUs in order to support trilinear filtering
+ * - I have bought a Voodoo2 board !
+ * - the amount of frambuffer ram is now doubled when an SLI configuration
+ * is detected
+ * - solved a problem related to the fxDDTexParam() and fxTexInvalidate()
+ * functions (thanks to Rune Hasvold for highlighting the problem)
+ * - done some cleanup in the fxvsetup.c file, written
+ * the FXVSETUP_FUNC macro
+ * - done a lot of cleanup in data types and field names
+ *
+ * Rune Hasvold (runeh@ifi.uio.no)
+ * - written the support for a right management of the auxiliary buffer.
+ * You can now use an 800x600 screen without the depth and alpha
+ * buffer
+ * - written the support for a new pixel format (without the depth
+ * and alpha buffer) in the WGL emulator
+ * - fixed a bug in the window version of the GLUT (it was ever asking
+ * for depth buffer)
+ *
+ * V0.23 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
+ * - included in the Mesa-3.0beta2 release
+ * - written the support for the OpenGL 1.2 GL_TEXTURE_BASE_LEVEL
+ * and GL_TEXTURE_MAX_LEVEL
+ * - rewritten several functions for a more clean support of texture
+ * mapping and in order to solve some bug
+ * - the accumulation buffer works (it is bit slow beacuase it requires
+ * to read/write from/to the Voodoo frame buffer but it works)
+ * - fixed a bug in the fxDDReadRGBASpan driver function (the R and
+ * B channels were read in the wrong order). Thanks to Jason Heym
+ * for highlighting the problem
+ * - written the support for multiple contexts on multiple boards.
+ * you can now use the Mesa/Voodoo with multiple Voodoo Graphics
+ * boards (for example with multiple screens or an HMD)
+ * - the fxBestResolution() now check all available resolutions
+ * and it is able to check the amount of framebuffer memory
+ * before return a resolution
+ * - modified the GLX/X11 driver in order to support all the
+ * resolution available
+ * - changed all function names. They should be now a bit more
+ * readable
+ * - written the Glide grVertex setup code for two TMU or
+ * for Multitexture support with emulationa dn one TMU
+ * - written the support for the new Mesa driver
+ * function GetParametri
+ * - small optimization/clean up in the texbind() function
+ * - fixed a FPU precision problem for glOrtho and texture
+ * mapping (thanks to Antti Juhani Huovilainen for an example
+ * of the problem)
+ * - written some small SGI OpenGL emulation code for the wgl,
+ * the OpenGL Optimizer and Cosmo3D work fine under windows !
+ * - moved the point/line/triangle/quad support in the fxmesa7.c
+ * - fixed a bug in the clear_color_depth() (thanks to Henk Kok
+ * for an example of the problem)
+ * - written a small workaround for Linux GLQuake, it asks
+ * for the alpha buffer and the depth buffer at the some time
+ * (but it never uses the alpha buffer)
+ * - checked the antialiasing points, lines and polygons support.
+ * It works fine
+ * - written the support for standard OpenGL antialiasing using
+ * blending. Lines support works fine (tested with BZflag)
+ * while I have still to check the polygons and points support
+ * - written the support for the alpha buffer. The driver is now
+ * able to use the Voodoo auxiliary buffer as an alpha buffer
+ * instead of a depth buffer. Also all the OpenGL blending
+ * modes are now supported. But you can't request a context
+ * with an alpha buffer AND a depth buffer at the some time
+ * (this is an hardware limitation)
+ * - written the support for switching between the fullscreen
+ * rendering and the in-window-rendering hack on the fly
+ *
+ * Rune Hasvold (runeh@ifi.uio.no)
+ * - fixed a bug in the texparam() function
+ *
+ * Brian Paul (brianp@elastic.avid.com) Avid Technology
+ * - sources accomodated for the new Mesa 3.0beta1
+ *

+ * - included with some v0.23 bug fix in the final release
+ * of the Mesa-2.6
+ * - written the support for the MESA_WGL_FX env. var. but
+ * not tested because I have only Voodoo Graphics boards
+ * - fixed a bug in the backface culling code
+ * (thanks to David Farrell for an example of the problem)
+ * - fixed the "Quake2 elevator" bug
+ * - GL_POLYGONS with 3/4 vertices are now drawn as
+ * GL_TRIANLGES/GL_QUADS (a small optimization for GLQuake)
+ * - fixed a bug in fxmesa6.h for GL_LINE_LOOP
+ * - fixed a NearFarStack bug in the Mesa when applications
+ * directly call glLoadMatrix to load a projection matrix
+ * - done some cleanup in the fxmesa2.c file
+ * - the driver no longer translates the texture maps
+ * when the Mesa internal format and the Voodoo
+ * format are the some (usefull for 1 byte texture maps
+ * where the driver can directly use the Mesa texture
+ * map). Also the amount of used memory is halfed
+ * - fixed a bug for GL_DECAL and GL_RGBA
+ * - fixed a bug in the clear_color_depth()
+ * - tested the v0.22 with the Mesa-2.6beta2. Impressive
+ * performances improvement thanks to the new Josh's
+ * asm code (+10fps in the isosurf demo, +5fps in GLQuake
+ * TIMEREFRESH)
+ * - written a optimized version of the RenderVB Mesa driver
+ * function. The Voodoo driver is now able to upload polygons
+ * in the most common cases at a very good speed. Good
+ * performance improvement for large set of small polygons
+ * - optimized the asm code for setting up the color information
+ * in the Glide grVertex structure
+ * - fixed a bug in the fxmesa2.c asm code (the ClipMask[]
+ * wasn't working)
+ *
+ * Josh Vanderhoof (joshv@planet.net)
+ * - removed the flush() function because it isn't required
+ * - limited the maximum number of swapbuffers in the Voodoo
+ * commands FIFO (controlled by the env. var. MESA_FX_SWAP_PENDING)
+ *
+ * Holger Kleemiss (holger.kleemiss@metronet.de) STN Atlas Elektronik GmbH
+ * - applied some patch for the Voodoo Rush
+ *
+ * V0.21 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
+ * - the driver is now able to take advantage of the ClipMask[],
+ * ClipOrMask and ClipAndMask information also under Windows
+ * - introduced a new function in the Mesa driver interface
+ * ClearColorAndDepth(). Now the glClear() function is
+ * 2 times faster (!) when you have to clear the color buffer
+ * and the depth buffer at some time
+ * - written the first version of the fxRenderVB() driver
+ * function
+ * - optimized the glTexImage() path
+ * - removed the fxMesaTextureUsePalette() support
+ * - fixed a bug in the points support (thanks to David Farrell
+ * for an example of the problem)
+ * - written the optimized path for glSubTexImage(),
+ * introduced a new function in the Mesa driver interface
+ * TexSubImage(...)
+ * - fixed a bug for glColorMask and glDepthMask
+ * - the wbuffer is not more used. The Voodoo driver uses
+ * a standard 16bit zbuffer in all cases. It is more consistent
+ * and now GLQuake and GLQuake2test work also with a GL_ZTRICK 0
+ * - the driver is now able to take advantage of the ClipMask[],
+ * ClipOrMask and ClipAndMask information (under Linux);
+ * - rewritten the setup_fx_units() function, now the texture
+ * mapping support is compliant to the OpenGL specs (GL_BLEND
+ * support is still missing). The LinuxGLQuake console correctly
+ * fade in/out and transparent water of GLQuake2test works fine
+ * - written the support for the env. var. FX_GLIDE_SWAPINTERVAL
+ * - found a bug in the Mesa core. There is a roundup problem for
+ * color values out of the [0.0,1.0] range
+ *
+ * Wonko <matt@khm.de>
+ * - fixed a Voodoo Rush related problem in the fxwgl.c
+ *
+ * Daryll Strauss <daryll@harlot.rb.ca.us>
+ * - written the scissor test support
+ *
+ * V0.20 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
+ * - written the closetmmanger() function in order to free all the memory
+ * allocated by the Texture Memory Manager (it will be useful
+ * when the support for multiple contexts/boards will be ready)
+ * - now the Voodoo driver runs without printing any information,
+ * define the env. var. MESA_FX_INFO if you want to read some
+ * information about the hardware and some statistic
+ * - written a small workaround for the "GLQuake multiplayer white box bug"
+ * in the setup_fx_units() funxtions. I'm already rewriting
+ * this function because it is the source of nearly all the current
+ * Voodoo driver problems
+ * - fixed the GLQuake texture misalignment problem (the texture
+ * coordinates must be scaled between 0.0 and 256.0 and not
+ * between 0.0 and 255.0)
+ * - written the support for the GL_EXT_shared_texture_palette
+ * - some small change for supporting the automatic building of the
+ * OpenGL32.dll under the Windows platform
+ * - the redefinition of a mipmap level is now a LOT faster. This path
+ * is used by GLQuake for dynamic lighting with some call to glTexSubImage2D()
+ * - the texture memory is now managed a set of 2MB blocks so
+ * texture maps can't be allocated on a 2MB boundary. The new Pure3D
+ * needs this kind of support (and probably any other Voodoo Graphics
+ * board with more than 2MB of texture memory)
+ *
+ * Brian Paul (brianp@elastic.avid.com) Avid Technology
+ * - added write_monocolor_span(), fixed bug in write_color_span()
+ * - added test for stenciling in choosepoint/line/triangle functions
+ *
+ * Joe Waters (falc@attila.aegistech.com) Aegis
+ * - written the support for the env. var. SST_SCREENREFRESH
+ *
+ * V0.19 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
+ * - written the 3Dfx Global Palette extension for GLQuake
+ * - written the support for the GL_EXT_paletted_texture (it works only with GL_RGBA
+ * palettes and the alpha value is ignored ... this is a limitation of the
+ * the current Glide version and Voodoo hardware)
+ * - fixed the amount of memory allocated for 8bit textures
+ * - merged the under construction v0.19 driver with the Mesa 2.5
+ * - finally written the support for deleting textures
+ * - introduced a new powerful texture memory manager: the texture memory
+ * is used as a cache of the set of all defined texture maps. You can
+ * now define several MB of texture maps also with a 2MB of texture memory
+ * (the texture memory manager will do automatically all the swap out/swap in
+ * work). The new texture memory manager has also
+ * solved a lot of other bugs/no specs compliance/problems
+ * related to the texture memory usage. The texture
+ * manager code is inside the new fxmesa3.c file
+ * - broken the fxmesa.c file in two files (fxmesa1.c and fxmesa2.c)
+ * and done some code cleanup
+ * - now is possible to redefine texture mipmap levels already defined
+ * - fixed a problem with the amount of texture memory allocated for textures
+ * with not all mipmap levels defined
+ * - fixed a small problem with single buffer rendering
+ *
+ * Brian Paul (brianp@elastic.avid.com) Avid Technology
+ * - read/write_color_span() now use front/back buffer correctly

+ * - removed a few ^M characters from fxmesa2.c file
+ *
+ * V0.18 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
+ * - the Mesa-2.4beta3 is finally using the driver quads support (the
+ * previous Mesa versions have never taken any advantage from the quads support !)
+ * - tested with the Glide 2.4 for Win
+ * - ported all asm code to Linux
+ * - ported the v0.18 to Linux (without asm code)
+ * - back to Linux !!!
+ * - optimized the SETUP macro (no more vertex snap for points and lines)

+ * - the Mesa/Voodoo is now 20/30% for points, lines and small triangles !
+ * - performance improvement setting VBSIZE to 72
+ * - the GrVertex texture code is now written in asm
+ * - the GrVertex zbuffer code is now written in asm
+ * - the GrVertex wbuffer code is now written in asm
+ * - the GrVertex gouraud code is now written in asm
+ * - the GrVertex snap code is now written in asm
+ * - changed the 8bit compressed texture maps in 8bit palette texture maps
+ * support (it has the some advantage of compressed texture maps without the
+ * problem of a fixed NCC table for all mipmap levels)
+ * - written the support for 8bit compressed texture maps (but texture maps with
+ * more than one mipmap level aren't working fine)
+ * - finnaly everthing is working fine in MesaQuake !
+ * - fixed a bug in the computation of texture mapping coordinates (I have found
+ * the bug thanks to MesaQuake !)

+ * Diego Picciani (d.picciani@novacomp.it) Nova Computer s.r.l.
+ * - written the fxCloseHardware() and the fxQuaryHardware() (mainly
+ * for the VoodooWGL emulator)
+ *
+ * Brian Paul (brianp@elastic.avid.com) Avid Technology
+ * - implemented read/write_color_span() so glRead/DrawPixels() works
+ * - now needs Glide 2.3 or later. Removed GLIDE_FULL_SCREEN and call to grSstOpen()

+ The Architectures currently supported by the DRI have grown

-<p>
- 3D acceleration is currently only available for systems with
- Intel-compatible CPUs.
- Support for Alpha, and perhaps other CPUs, should be available in the
- future.

+ The build environment for both of these new architectures
+ have a pre-build environment that will correctly build the
+ DRI drivers and Mesa meaning no extra configuration is necessary
+ to build the DRI for these architectures.
+
+ <sect2>Alpha Features
+ <p>
+ On newer Alpha processors, it should be noted that a
+ significant performance increase can be seen with the
+ addition of the -mcpu= command that should be passed to
+ GCC upon compilation. Dependent of the architecture of the
+ processor, for example -mcpu=ev6 will build specifically
+ for the EV6 based AXP's, giving both byte and word alignment
+ access to the DRI/Mesa drivers.
+
+ Use this as an example of compiling with this extra speed.
+ In your host.def file that should reside in the xc/config
+ directory, add the line.
+
+ #define DefaultCCOptions -ansi GccWarningOptions -pipe -mcpu=ev6
+
+ Additional speed improvements to 3D rendering can be achieved
+ by installing Compaq's Math Libraries (CPML) which can be
+ obtained from the following URL.
+
+ http://www.support.compaq.com/alpha-tools/software/index.html

the vga graphics index & port (GraphicsIndexReg : 0x63ce, GraphicsPort :

pm3 drm kernel driver as well as a pm3 OpenGL driver. Could be useful for
boards without gamma chips though.
+ * Claiming the Gamma (in the one head only approach) :
+ - The first possibility is the use of the UseGamma Option in the driver
+ section. The UseGamma option then tries to claim a gamma chip, if
+ available, on the same device. This enable the use of the gamma on
+ either head, in a two head setup.
+ - The second possibility is the automatic claiming of a gamma chip if
+ available. This works ok in single headed mode, but in dual head setup,
+ only the first head will be accelerated.
+ * Using the Gamma :
+ - A first try of using the Gamma (for 2D only) gave me a system freeze.
+ This is probably due to bad initialization since i only set the IOBase
+ to the Gamma registers, and did nothing more to initialize the Gamma.
+ I need more info on initialization of the Gamma chip, especially on how
+ to tell it which Permedia3 to use.
+ - A Second try, after initializing MultiGLINTAperture and MultiGLINT1 did
+ end in the same way.
+ - Once that is done, i need to write a pm3_dri.c file, inspired on the
+ glint_dri.c file, which does the dri setup, and the 2d/3d state saving.
+ * Changes to the 2D driver when using the Gamma :
+ - Well, there could be some changes, but in particular, the Gamma has only
+ a 32 entries deep Input FIFO, and not a 120 entries deep one like
+ permedia3.
