-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

- * 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.
- *
