appropriate hardware driver for each screen on the local X display.
The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/
directory. Drivers are named with the convention <name>_dri.so where
-<name> is a driver such as "tdfx", "i810", "gamma", etc.
+<name> is a driver such as "radeon", "i965", "nouveau", etc.
The LIBGL_DRIVERS_DIR environment variable may be used to specify a
different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/.

- * union {
- * struct {
- * float x, y, z, w;
- * struct { char r, g, b, a; } color;
- * struct { char r, g, b, fog; } spec;

- * struct { char r, g, b, a; } color;
- * struct { char r, g, b, fog; } spec;
- * float u0, v0, q0;
- * float u1, v1, q1;
- * float u2, v2, q2;
- * float u3, v3, q3;
- * } pv;
- * struct {
- * float x, y, z;
- * struct { char r, g, b, a; } color;
- * } tv;
- * float f[16];
- * unsigned int ui[16];
- * unsigned char ub4[4][16];
- * }
- *
-
- * DO_XYZW: Emit xyz and maybe w coordinates.
- * DO_RGBA: Emit color.
- * DO_SPEC: Emit specular color.
- * DO_FOG: Emit fog coordinate in specular alpha.
- * DO_TEX0: Emit tex0 u,v coordinates.
- * DO_TEX1: Emit tex1 u,v coordinates.
- * DO_TEX2: Emit tex2 u,v coordinates.
- * DO_TEX3: Emit tex3 u,v coordinates.
- * DO_PTEX: Emit tex0,1,2,3 q coordinates where possible.
- *
- * HAVE_RGBA_COLOR: Hardware takes color in rgba order (else bgra).
- *
- * HAVE_HW_VIEWPORT: Hardware performs viewport transform.
- * HAVE_HW_DIVIDE: Hardware performs perspective divide.
- *
- * HAVE_TINY_VERTICES: Hardware understands v.tv format.
- * HAVE_PTEX_VERTICES: Hardware understands v.pv format.
- * HAVE_NOTEX_VERTICES: Hardware understands v.v format with texcount 0.
- *
- * Additionally, this template assumes it is emitting *transformed*
- * vertices; the modifications to emit untransformed vertices (ie. to
- * t&l hardware) are probably too great to cooexist with the code
- * already in this file.
- *
- * NOTE: The PTEX vertex format always includes TEX0 and TEX1, even if
- * only TEX0 is enabled, in order to maintain a vertex size which is
- * an exact number of quadwords.

-MGA DRI driver ported from XF86DRI to FBDRI
-by Denis Oliver Kropp <dok@directfb.org>
-
-
-INFO
-
-This driver has been ported from the head branch of XFree86 to
-the embedded-1-branch of Mesa.
-
-
-STATUS
-
-Already working very well as far as I've tested it (16/32 bit).
-glxgears runs at 935 fps (G550 32MB AGP 4x, Athlon 1.33) vs 744 fps with XFree.
-Other demos (terrain, fire, etc.) have been successfully tested as well.
-
-
-TODO
-
-- mgaEngineShutdown
-- mgaEngineRestore
-- SGRAM detection
-- remove some unused bits from server/*
-- subset driver support
-- mgaWaitForVBlank
-- deinitialization (from MGADRICloseScreen) a la radeonDestroyScreen

- /* The G200 only has the ability to use 5 mipmap levels (including the
- * base level). The G400 does not have this restriction, but it still
- * only has 5 offset pointers in the hardware. The trick on the G400 is
- * upto the first 4 offset pointers point to mipmap levels. The last
- * offset pointer tells how large the preceeding mipmap is. This value is
- * then used to determine where the remaining mipmaps are.
- *
- * For example, if the first offsets[0] through offsets[2] are used as
- * pointers, then offset[3] will be the size of the mipmap pointed to by
- * offsets[2]. So mipmap level 3 will be at (offsets[2]+offsets[3]). For
- * each successive mipmap level, offsets[3] is divided by 4 and added to
- * the previous address. So mipmap level 4 will be at
- * (offsets[2]+offsets[3]+(offsets[3] / 4)).
- *
- * The last pointer is selected by setting TO_texorgoffsetsel in its
- * pointer. In the previous example, offset[2] would have
- * TO_texorgoffsetsel or'ed in before writing it to the hardware.
- *
- * In the current driver all of the mipmaps are packed together linearly
- * with mipmap level 0. Therefore offsets[0] points to the base of the
- * texture (and has TO_texorgoffsetsel or'ed in), and offsets[1] is the
- * size of the base texture.
- *
- * There is a possible optimization available here. At times the driver
- * may not be able to allocate a single block of memory for the complete
- * texture without ejecting some other textures from memory. It may be
- * possible to put some of the lower mipmap levels (i.e., the larger
- * mipmaps) in memory separate from the higher levels.
- *
- * The implementation should be fairly obvious, but getting "right" would
- * likely be non-trivial. A first allocation for the entire texture would
- * be attempted with a flag that says "don't eject other textures." If
- * that failed, an additional allocation would be attmpted for just the
- * base map. The process would repeat with the block of lower maps. The
- * tricky parts would be in detecting when some of the levels had been
- * ejected from texture memory by other textures and preventing the
- * 4th allocation (for all the smallest mipmap levels) from kicking out
- * any of the first three.
- *
- * This array holds G400_TEX_MAXLEVELS pointers to remove an if-statement
- * in a loop in mgaSetTexImages. Values past G200_TEX_MAXLEVELS are not

-OUTSTANDING BUGS
-
-demos/reflect - reading back Z on Voodoo3, image offset to right
- Fixed in latest Glide.
-
-Q3 - some polygons drawn as vertical strips, similar to bug that was
- seen in demos/fire. Voodoo3 only. May be related to glDepthMask
- or glColorMask.
-
-book/fog - not fogging
- Fog in orthograph mode still not implemented. Checking with
- 3dfx engineers for ideas.
-
-Q3 demo crashes after changing display settings
- but the full Q3 game version seems OK.
-
-
-
-MORE OUTSTANDING BUGS
-
-private context was NULL! causing immediate failure of any glx prog. cant
-reproduce after restarting the X server. putting it down as halluc.
-
-texture object image was NULL, causing segmentation failure. happens with
-prboom. ive put a check in tdfx_texstate.c but this isn't a fix.
-
-prboom, wall textures near first chainsaw aren't bound properly. sideways
-movements causes the wall textures to move with you. prboom busted?
-
-16bpp mode, quake3, windowed, q3dm1, floor under rocketlauncher bands. it
-looks like multitexturing gone wrong. i'll disable a tmu and test.
-
-sof, polygons appear at wrong x,y,z positions, intermittent, have not yet
-found reliable way of reproducing. culling? sometimes polys disappear.
-
-descent3 is all black in 16bpp mode - FIXED (palette problems)
-
-smeared pixels in quake3 - FIXED (texture memory overlapped FB)
-
-

- * Because the Linear Frame Buffer is not necessarily aligned
- * with the depth buffer, we have to do some fiddling
- * around to get the right addresses.
- *
- * Perhaps a picture is in order. The Linear Frame Buffer
- * looks like this:
- *
- * |<----------------------info.strideInBytes------------->|
- * |<-----physicalStrideInBytes------->|
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- * | | |
- * | Legal Memory | Forbidden Zone |
- * | | |
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- *
- * You can only reliably read and write legal locations. Reads
- * and writes from the Forbidden Zone will return undefined values,
- * and may cause segmentation faults.
- *
- * Now, the depth buffer may not end up in a location such each
- * scan line is an LFB line. For example, the depth buffer may
- * look like this:
- *
- * wrapped ordinary.
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- * |0000000000000000000000 | | back
- * |1111111111111111111111 | | buffer
- * |2222222222222222222222 | |
- * |4096b align. padxx00000000000000000| Forbidden Zone | depth
- * |0000 11111111111111111| | buffer
- * |1111 22222222222222222| |
- * |2222 | |
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- * where each number is the scan line number. We know it will
- * be aligned on 128 byte boundaries, at least. Aligning this
- * on a scanline boundary causes the back and depth buffers to
- * thrash in the SST1 cache. (Note that the back buffer is always
- * allocated at the beginning of LFB memory, and so it is always
- * properly aligned with the LFB stride.)
- *
- * We call the beginning of the line (which is the rightmost
- * part of the depth line in the picture above) the *ordinary* part
- * of the scanline, and the end of the line (which is the
- * leftmost part, one line below) the *wrapped* part of the scanline.
- * a.) We need to know what x value to subtract from the screen
- * x coordinate to index into the wrapped part.
- * b.) We also need to figure out if we need to read from the ordinary
- * part scan line, or from the wrapped part of the scan line.
- *
- * [ad a]
- * The first wrapped x coordinate is that coordinate such that
- * depthBufferOffset&(info.strideInBytes) + x*elmentSize {*}
- * > physicalStrideInBytes
- * where depthBufferOffset is the LFB distance in bytes
- * from the back buffer to the depth buffer. The expression
- * depthBufferOffset&(info.strideInBytes)
- * is then the offset (in bytes) from the beginining of (any)
- * depth buffer line to first element in the line.
- * Simplifying inequation {*} above we see that x is the smallest
- * value such that
- * x*elementSize > physicalStrideInBytes {**}
- * - depthBufferOffset&(info.strideInBytes)
- * Now, we know that both the summands on the right are multiples of
- * 128, and elementSize <= 4, so if equality holds in {**}, x would
- * be a multiple of 32. Thus we can set x to
- * xwrapped = (physicalStrideInBytes
- * - depthBufferOffset&(info.strideInBytes))/elementSize
- * + 1
- *
- * [ad b]
- * Question b is now simple. We read from the wrapped scan line if
- * x is greater than xwrapped.

The default pipeline is specified in t_pipeline.c, and is usually a
starting point for driver pipelines. Some drivers will remove a stage
where hardware provides support for the implemented operation (for
-instance fog where per-pixel hardware fog is available, as in the dri
-tdfx driver), or add stages to shortcircuit latter operations (for
+instance fog where per-pixel hardware fog is available),
+or add stages to shortcircuit latter operations (for
example taking advantage of hardware support for strips and other
higher-level primitives (for example the radeon driver).
