gallium: michel's patch to rework texture/sampler binding interface

Bind all the samplers/textures at once rather than piecemeal.
This is easier for drivers to understand.

-/* Glossary:
- *
- * URB - uniform resource buffer.  A mid-sized buffer which is
- * partitioned between the fixed function units and used for passing
- * values (vertices, primitives, constants) between them.
- *
- * CURBE - constant URB entry.  An urb region (entry) used to hold
- * constant values which the fixed function units can be instructed to
- * preload into the GRF when spawining a thread.
- *
- * VUE - vertex URB entry.  An urb entry holding a vertex and usually
- * a vertex header.  The header contains control information and
- * things like primitive type, Begin/end flags and clip codes.
- *
- * PUE - primitive URB entry.  An urb entry produced by the setup (SF)
- * unit holding rasterization and interpolation parameters.
- *
- * GRF - general register file.  One of several register files
- * addressable by programmed threads.  The inputs (r0, payload, curbe,
- * urb) of the thread are preloaded to this area before the thread is
- * spawned.  The registers are individually 8 dwords wide and suitable
- * for general usage.  Registers holding thread input values are not
- * special and may be overwritten.
- *
- * MRF - message register file.  Threads communicate (and terminate)
- * by sending messages.  Message parameters are placed in contigous
- * MRF registers.  All program output is via these messages.  URB
- * entries are populated by sending a message to the shared URB
- * function containing the new data, together with a control word,
- * often an unmodified copy of R0.
- *
- * R0 - GRF register 0.  Typically holds control information used when
- * sending messages to other threads.
- *
- * EU or GEN4 EU: The name of the programmable subsystem of the
- * i965 hardware.  Threads are executed by the EU, the registers
- * described above are part of the EU architecture.
- *
- * Fixed function units:
- *
- * CS - Command streamer.  Notional first unit, little software
- * interaction.  Holds the URB entries used for constant data, ie the
- * CURBEs.
- *
- * VF/VS - Vertex Fetch / Vertex Shader.  The fixed function part of
- * this unit is responsible for pulling vertices out of vertex buffers
- * in vram and injecting them into the processing pipe as VUEs.  If
- * enabled, it first passes them to a VS thread which is a good place
- * for the driver to implement any active vertex shader.
- *
- * GS - Geometry Shader.  This corresponds to a new DX10 concept.  If
- * enabled, incoming strips etc are passed to GS threads in individual
- * line/triangle/point units.  The GS thread may perform arbitary
- * computation and emit whatever primtives with whatever vertices it
- * chooses.  This makes GS an excellent place to implement GL's
- * unfilled polygon modes, though of course it is capable of much
- * more.  Additionally, GS is used to translate away primitives not
- * handled by latter units, including Quads and Lineloops.
- *
- * CS - Clipper.  Mesa's clipping algorithms are imported to run on
- * this unit.  The fixed function part performs cliptesting against
- * the 6 fixed clipplanes and makes descisions on whether or not the
- * incoming primitive needs to be passed to a thread for clipping.
- * User clip planes are handled via cooperation with the VS thread.
- *
- * SF - Strips Fans or Setup: Triangles are prepared for
- * rasterization.  Interpolation coefficients are calculated.
- * Flatshading and two-side lighting usually performed here.
- *
- * WM - Windower.  Interpolation of vertex attributes performed here.
- * Fragment shader implemented here.  SIMD aspects of EU taken full
- * advantage of, as pixels are processed in blocks of 16.
- *
- * CC - Color Calculator.  No EU threads associated with this unit.
- * Handles blending and (presumably) depth and stencil testing.

+/* Glossary:

+ *

+ * URB - uniform resource buffer.  A mid-sized buffer which is

+ * partitioned between the fixed function units and used for passing

+ * values (vertices, primitives, constants) between them.

+ *

+ * CURBE - constant URB entry.  An urb region (entry) used to hold

+ * constant values which the fixed function units can be instructed to

+ * preload into the GRF when spawining a thread.

+ *

+ * VUE - vertex URB entry.  An urb entry holding a vertex and usually

+ * a vertex header.  The header contains control information and

+ * things like primitive type, Begin/end flags and clip codes.

+ *

+ * PUE - primitive URB entry.  An urb entry produced by the setup (SF)

+ * unit holding rasterization and interpolation parameters.

+ *

+ * GRF - general register file.  One of several register files

+ * addressable by programmed threads.  The inputs (r0, payload, curbe,

+ * urb) of the thread are preloaded to this area before the thread is

+ * spawned.  The registers are individually 8 dwords wide and suitable

+ * for general usage.  Registers holding thread input values are not

+ * special and may be overwritten.

+ *

+ * MRF - message register file.  Threads communicate (and terminate)

+ * by sending messages.  Message parameters are placed in contigous

+ * MRF registers.  All program output is via these messages.  URB

+ * entries are populated by sending a message to the shared URB

+ * function containing the new data, together with a control word,

+ * often an unmodified copy of R0.

+ *

+ * R0 - GRF register 0.  Typically holds control information used when

+ * sending messages to other threads.

+ *

+ * EU or GEN4 EU: The name of the programmable subsystem of the

+ * i965 hardware.  Threads are executed by the EU, the registers

+ * described above are part of the EU architecture.

+ *

+ * Fixed function units:

+ *

+ * CS - Command streamer.  Notional first unit, little software

+ * interaction.  Holds the URB entries used for constant data, ie the

+ * CURBEs.

+ *

+ * VF/VS - Vertex Fetch / Vertex Shader.  The fixed function part of

+ * this unit is responsible for pulling vertices out of vertex buffers

+ * in vram and injecting them into the processing pipe as VUEs.  If

+ * enabled, it first passes them to a VS thread which is a good place

+ * for the driver to implement any active vertex shader.

+ *

+ * GS - Geometry Shader.  This corresponds to a new DX10 concept.  If

+ * enabled, incoming strips etc are passed to GS threads in individual

+ * line/triangle/point units.  The GS thread may perform arbitary

+ * computation and emit whatever primtives with whatever vertices it

+ * chooses.  This makes GS an excellent place to implement GL's

+ * unfilled polygon modes, though of course it is capable of much

+ * more.  Additionally, GS is used to translate away primitives not

+ * handled by latter units, including Quads and Lineloops.

+ *

+ * CS - Clipper.  Mesa's clipping algorithms are imported to run on

+ * this unit.  The fixed function part performs cliptesting against

+ * the 6 fixed clipplanes and makes descisions on whether or not the

+ * incoming primitive needs to be passed to a thread for clipping.

+ * User clip planes are handled via cooperation with the VS thread.

+ *

+ * SF - Strips Fans or Setup: Triangles are prepared for

+ * rasterization.  Interpolation coefficients are calculated.

+ * Flatshading and two-side lighting usually performed here.

+ *

+ * WM - Windower.  Interpolation of vertex attributes performed here.

+ * Fragment shader implemented here.  SIMD aspects of EU taken full

+ * advantage of, as pixels are processed in blocks of 16.

+ *

+ * CC - Color Calculator.  No EU threads associated with this unit.

+ * Handles blending and (presumably) depth and stencil testing.
