+ *
+ * DESCRIPTION
+ *
+ * This file contains a straightforward implementation of a fixed-sized
+ * hash table using self-organizing linked lists [Knuth73, pp. 398-399] for
+ * collision resolution. There are two potentially interesting things
+ * about this implementation:
+ *
+ * 1) The table is power-of-two sized. Prime sized tables are more
+ * traditional, but do not have a significant advantage over power-of-two
+ * sized table, especially when double hashing is not used for collision
+ * resolution.
+ *
+ * 2) The hash computation uses a table of random integers [Hanson97,
+ * pp. 39-41].
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * With a table size of 512, the current implementation is sufficient for a
+ * few hundred keys. Since this is well above the expected size of the
+ * tables for which this implementation was designed, the implementation of
+ * dynamic hash tables was postponed until the need arises. A common (and
+ * naive) approach to dynamic hash table implementation simply creates a
+ * new hash table when necessary, rehashes all the data into the new table,
+ * and destroys the old table. The approach in [Larson88] is superior in
+ * two ways: 1) only a portion of the table is expanded when needed,
+ * distributing the expansion cost over several insertions, and 2) portions
+ * of the table can be locked, enabling a scalable thread-safe
+ * implementation.

+ *
+ * DESCRIPTION
+ *
+ * This file contains a simple, straightforward implementation of the Park
+ * & Miller "Minimal Standard" PRNG [PM88, PMS93], which is a Lehmer
+ * multiplicative linear congruential generator (MLCG) with a period of
+ * 2^31-1.
+ *
+ * This implementation is intended to provide a reliable, portable PRNG
+ * that is suitable for testing a hash table implementation and for
+ * implementing skip lists.
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * If initial seeds are not selected randomly, two instances of the PRNG
+ * can be correlated. [Knuth81, pp. 32-33] describes a shuffling technique
+ * that can eliminate this problem.
+ *
+ * If PRNGs are used for simulation, the period of the current
+ * implementation may be too short. [LE88] discusses methods of combining
+ * MLCGs to produce much longer periods, and suggests some alternative
+ * values for A and M. [LE90 and Sch92] also provide information on
+ * long-period PRNGs.

+************************************************************

+************************************************************
+
+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://precisioninsight.com/piinsights.html
+
+For specific information about kernel-level support, see:
+
+ The Direct Rendering Manager, Kernel Support for the Direct Rendering
+ Infrastructure

+
+ Hardware Locking for the Direct Rendering Infrastructure

+************************************************************

+************************************************************
+
+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://precisioninsight.com/piinsights.html
+
+For specific information about kernel-level support, see:
+
+ The Direct Rendering Manager, Kernel Support for the Direct Rendering
+ Infrastructure

+/**
+ * \mainpage
+ *
+ * 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:
+ * -# The DRM provides synchronized access to the graphics hardware via
+ * the use of an optimized two-tiered lock.
+ * -# 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.
+ * -# The DRM provides a generic DMA engine, complete with multiple
+ * queues and the ability to detect the need for an OpenGL context
+ * switch.
+ * -# The DRM is extensible via the use of small device-specific modules
+ * that rely extensively on the API exported by the DRM module.

+// 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
+// - 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 alll 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 */

+/* 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

+ *
+ * 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:
+ * -# The DRM provides synchronized access to the graphics hardware via
+ * the use of an optimized two-tiered lock.
+ * -# 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.
+ * -# The DRM provides a generic DMA engine, complete with multiple
+ * queues and the ability to detect the need for an OpenGL context
+ * switch.
+ * -# The DRM is extensible via the use of small device-specific modules
+ * that rely extensively on the API exported by the DRM module.

+ * - 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
