+************************************************************
+* For the very latest on DRI development, please see:      *
+*     http://dri.freedesktop.org/                          *
+************************************************************
+
+The Direct Rendering Manager (drm) is a device-independent kernel-level
+device driver that provides support for the XFree86 Direct Rendering
+Infrastructure (DRI).
+
+The DRM supports the Direct Rendering Infrastructure (DRI) in four major
+ways:
+
+    1. The DRM provides synchronized access to the graphics hardware via
+       the use of an optimized two-tiered lock.
+
+    2. The DRM enforces the DRI security policy for access to the graphics
+       hardware by only allowing authenticated X11 clients access to
+       restricted regions of memory.
+
+    3. The DRM provides a generic DMA engine, complete with multiple
+       queues and the ability to detect the need for an OpenGL context
+       switch.
+
+    4. The DRM is extensible via the use of small device-specific modules
+       that rely extensively on the API exported by the DRM module.
+
+
+Documentation on the DRI is available from:
+    http://dri.freedesktop.org/wiki/Documentation
+    http://sourceforge.net/project/showfiles.php?group_id=387
+    http://dri.sourceforge.net/doc/

+    Infrastructure

+/* ALU
+ * The ALU instructions register blocks are enumerated according to the order
+ * in which fglrx. I assume there is space for 64 instructions, since
+ * each block has space for a maximum of 64 DWORDs, and this matches reported
+ * native limits.
+ *
+ * The basic functional block seems to be one MAD for each color and alpha,
+ * and an adder that adds all components after the MUL.
+ *  - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
+ *  - DP4: Use OUTC_DP4, OUTA_DP4
+ *  - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
+ *  - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
+ *  - CMPH: If ARG2 > 0.5, return ARG0, else return ARG1
+ *  - CMP: If ARG2 < 0, return ARG1, else return ARG0
+ *  - FLR: use FRC+MAD
+ *  - XPD: use MAD+MAD
+ *  - SGE, SLT: use MAD+CMP
+ *  - RSQ: use ABS modifier for argument
+ *  - Use OUTC_REPL_ALPHA to write results of an alpha-only operation
+ *    (e.g. RCP) into color register
+ *  - apparently, there's no quick DST operation
+ *  - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
+ *  - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
+ *  - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
+ *
+ * Operand selection
+ * First stage selects three sources from the available registers and
+ * constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
+ * fglrx sorts the three source fields: Registers before constants,
+ * lower indices before higher indices; I do not know whether this is
+ * necessary.
+ *
+ * fglrx fills unused sources with "read constant 0"
+ * According to specs, you cannot select more than two different constants.
+ *
+ * Second stage selects the operands from the sources. This is defined in
+ * INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
+ * zero and one.
+ * Swizzling and negation happens in this stage, as well.
+ *
+ * Important: Color and alpha seem to be mostly separate, i.e. their sources
+ * selection appears to be fully independent (the register storage is probably
+ * physically split into a color and an alpha section).
+ * However (because of the apparent physical split), there is some interaction
+ * WRT swizzling. If, for example, you want to load an R component into an
+ * Alpha operand, this R component is taken from a *color* source, not from
+ * an alpha source. The corresponding register doesn't even have to appear in
+ * the alpha sources list. (I hope this all makes sense to you)
+ *
+ * Destination selection
+ * The destination register index is in FPI1 (color) and FPI3 (alpha)
+ * together with enable bits.
+ * There are separate enable bits for writing into temporary registers
+ * (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_*
+ * /DSTA_OUTPUT). You can write to both at once, or not write at all (the
+ * same index must be used for both).
+ *
+ * Note: There is a special form for LRP
+ *  - Argument order is the same as in ARB_fragment_program.
+ *  - Operation is MAD
+ *  - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
+ *  - Set FPI0/FPI2_SPECIAL_LRP
+ * Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD

+/* Every instruction is four dwords long:
+ *  DWORD 0: output and opcode
+ *  DWORD 1: first argument
+ *  DWORD 2: second argument
+ *  DWORD 3: third argument
+ *
+ * Notes:
+ *  - ABS r, a is implemented as MAX r, a, -a
+ *  - MOV is implemented as ADD to zero
+ *  - XPD is implemented as MUL + MAD
+ *  - FLR is implemented as FRC + ADD
+ *  - apparently, fglrx tries to schedule instructions so that there is at
+ *    least one instruction between the write to a temporary and the first
+ *    read from said temporary; however, violations of this scheduling are
+ *    allowed
+ *  - register indices seem to be unrelated with OpenGL aliasing to
+ *    conventional state
+ *  - only one attribute and one parameter can be loaded at a time; however,
+ *    the same attribute/parameter can be used for more than one argument
+ *  - the second software argument for POW is the third hardware argument
+ *    (no idea why)
+ *  - MAD with only temporaries as input seems to use VPI_OUT_SELECT_MAD_2
+ *
+ * There is some magic surrounding LIT:
+ *   The single argument is replicated across all three inputs, but swizzled:
+ *     First argument: xyzy
+ *     Second argument: xyzx
+ *     Third argument: xyzw
+ *   Whenever the result is used later in the fragment program, fglrx forces
+ *   x and w to be 1.0 in the input selection; I don't know whether this is
+ *   strictly necessary

+/* Interface history:
+ *
+ * 1.1 - ??
+ * 1.2 - Add vertex2 ioctl (keith)
+ *     - Add stencil capability to clear ioctl (gareth, keith)
+ *     - Increase MAX_TEXTURE_LEVELS (brian)
+ * 1.3 - Add cmdbuf ioctl (keith)
+ *     - Add support for new radeon packets (keith)
+ *     - Add getparam ioctl (keith)
+ *     - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
+ * 1.4 - Add scratch registers to get_param ioctl.
+ * 1.5 - Add r200 packets to cmdbuf ioctl
+ *     - Add r200 function to init ioctl
+ *     - Add 'scalar2' instruction to cmdbuf
+ * 1.6 - Add static GART memory manager
+ *       Add irq handler (won't be turned on unless X server knows to)
+ *       Add irq ioctls and irq_active getparam.
+ *       Add wait command for cmdbuf ioctl
+ *       Add GART offset query for getparam
+ * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
+ *       and R200_PP_CUBIC_OFFSET_F1_[0..5].
+ *       Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
+ *       R200_EMIT_PP_CUBIC_OFFSETS_[0..5].  (brian)
+ * 1.8 - Remove need to call cleanup ioctls on last client exit (keith)
+ *       Add 'GET' queries for starting additional clients on different VT's.
+ * 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl.
+ *       Add texture rectangle support for r100.
+ * 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which
+ *       clients use to tell the DRM where they think the framebuffer is
+ *       located in the card's address space
+ * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color
+ *       and GL_EXT_blend_[func|equation]_separate on r200
+ * 1.12- Add R300 CP microcode support - this just loads the CP on r300
+ *       (No 3D support yet - just microcode loading).
+ * 1.13- Add packet R200_EMIT_TCL_POINT_SPRITE_CNTL for ARB_point_parameters
+ *     - Add hyperz support, add hyperz flags to clear ioctl.
+ * 1.14- Add support for color tiling
+ *     - Add R100/R200 surface allocation/free support
+ * 1.15- Add support for texture micro tiling
+ *     - Add support for r100 cube maps
+ * 1.16- Add R200_EMIT_PP_TRI_PERF_CNTL packet to support brilinear
+ *       texture filtering on r200
+ * 1.17- Add initial support for R300 (3D).
+ * 1.18- Add support for GL_ATI_fragment_shader, new packets
+ *       R200_EMIT_PP_AFS_0/1, R200_EMIT_PP_TXCTLALL_0-5 (replaces
+ *       R200_EMIT_PP_TXFILTER_0-5, 2 more regs) and R200_EMIT_ATF_TFACTOR
+ *       (replaces R200_EMIT_TFACTOR_0 (8 consts instead of 6)
+ * 1.19- Add support for gart table in FB memory and PCIE r300
+ * 1.20- Add support for r300 texrect
+ * 1.21- Add support for card type getparam
+ * 1.22- Add support for texture cache flushes (R300_TX_CNTL)
+ * 1.23- Add new radeon memory map work from benh
+ * 1.24- Add general-purpose packet for manipulating scratch registers (r300)
+ * 1.25- Add support for r200 vertex programs (R200_EMIT_VAP_PVS_CNTL,
+ *       new packet type)
+ * 1.26- Add support for variable size PCI(E) gart aperture
+ * 1.27- Add support for IGP GART
+ * 1.28- Add support for VBL on CRTC2
+ * 1.29- R500 3D cmd buffer support
