Subject: [PATCH 003/166] glsl: implement loop unrolling for simple 'for' loops

Loops such as this will be unrolled:
  for (i = 0; i < 4; ++i) {
      body;
  }
where 'body' isn't too large.

This also helps to fix the issue reported in bug #19190.  The problem there
is indexing vector types with a variable index.  For example:
  vec4 v;
  v[2] = 1.0;  // equivalent to v.z = 1.0
  v[i] = 2.0;  // variable index into vector!!

Since the for-i loop can be unrolled, we can avoid the problems associated
with variable indexing into a vector (at least in this case).

Add a "max complexity" heuristic to allow unrolling long loops with small
bodies and short loops with large bodies.

The loop unroll limits may need further tweaking...

Subject: [PATCH 019/166] mesa: Remove _Active and _UseTexEnvProgram flags from
 fragment programs.

There was a note in state.c about _Active deserving to die, and there were
potential issues with it due to i965 forgetting to set _UseTexEnvProgram.
Removing both simplifies things.

Subject: [PATCH 023/166] glsl: fix broken +=, -=, *=, /= operators

These functions need to return the final computed value.
Now expressions such as a = (b += c) work properly.
Also, no need to use __asm intrinsics in these functions.  The resulting
code is the same when using ordinary arithmetic operators and is more legible.

+<H1>Mesa 7.2 Release Notes / 20 September 2008</H1>
+
+<p>
+Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a
+new development release.
+</p>
+<p>
+Mesa 7.2 implements the OpenGL 2.1 API, but the version reported by
+glGetString(GL_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 2.1.
+</p>
+<p>
+Note that this version of Mesa does not use the GEM memory manager.
+The master branch of git uses GEM.
+The prototype DRI2 code that was in 7.1 has also been removed.
+</p>
+<p>
+DRM version 2.3.1 should be used with Mesa 7.2

+<li>Fixed some issues with glBindAttribLocation()
+<li>Fixed crash in _tnl_InvalidateState() found with Amira (bug 15834)
+<li>Assorted bug fixes for Ming build

+<h2>To Do (someday) items</h2>
+<ul>
+<li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy().
+Probably do the same for malloc, calloc, etc.
+The wrappers were useful in the past for memory debugging but now we
+have valgrind.  Not worried about SunOS 4 support anymore either...

+<li>Fix linux-glide target/driver.

-As of February 2008 the driver supports smooth/flat shaded triangle rendering
-with Z testing and simple texture mapping.
-Simple demos like gears run successfully.
-To test texture mapping, try progs/demos/texcyl (press right mouse button for
-rendering options).
+As of October 2008, the driver runs quite a few OpenGL demos.
+Features that work include:
 </p>
+<ul>
+<li>Point/line/triangle rendering, glDrawPixels
+<li>2D, NPOT and cube texture maps with nearest/linear/mipmap filtering
+<li>Dynamic SPU code generation for fragment shaders, but not complete
+<li>Dynamic SPU code generation for fragment ops (blend, Z-test, etc), but not complete
+<li>Dynamic PPU/PPC code generation for vertex shaders, but not complete
+</ul>
+<p>
+Performance has recently improved with the addition of PPC code generation
+for vertex shaders, but the code quality isn't too great yet.
+</p>

+Another bottleneck is SwapBuffers.  It may be the limiting factor for
+many simple GL tests.

+
+<H2>Debug Options</H2>
+
+<p>
+The CELL_DEBUG env var can be set to a comma-separated list of one or
+more of the following debug options:
+</p>
+<ul>
+<li><b>checker</b> - use a different background clear color for each SPU.
+   This lets you see which SPU is rendering which screen tiles.
+<li><b>sync</b> - wait/synchronize after each DMA transfer
+<li><b>asm</b> - print generated SPU assembly code to stdout
+<li><b>fragops</b> - emit fragment ops debug messages
+<li><b>fragopfallback</b> - don't use codegen for fragment ops
+<li><b>cmd</b> - print SPU commands as their received
+<li><b>cache</b> - print texture cache statistics when program exits
+</ul>
+<p>
+Note that some of these options may only work for linux-cell-debug builds.
+</p>
+
+<p>
+If the GALLIUM_NOPPC env var is set, PPC code generation will not be used
+and vertex shaders will be run with the TGSI interpreter.
+</p>
+<p>
+If the GALLIUM_NOCELL env var is set, the softpipe driver will be used
+intead of the Cell driver.
+This is useful for comparison/validation.

Subject: [PATCH 033/166] glsl: make minimum struct size = 2, not 1

1-component structs such as "struct foo { float x; }" could get placed at
any position within a register.  This caused some trouble computing the
field offset which assumed all struct objects were placed at R.x.
It would be unusual to hit this case in normal shaders.

Subject: [PATCH 036/166] glsl: force creation of new scope for for-loop body

Fixes regression in progs/demos/convolution.c due to loop unrolling.
This also allows the following to be compiled correctly:
for (int i = 0; i < n; i++) {
   int i;
   ...
}
This fix is a bit of a hack, however.  The better fix would be to change
the slang_shader.syn grammar.  Will revisit that...

Subject: [PATCH 084/166] i965: fix broken ARB fp fog options

Just call _mesa_append_fog_code() if the fragment program's FogOption is
not GL_NONE.
This allows us to remove some unnecessary i965 fog code.
Note, the arbfplight.c demo can be used to test this (see DO_FRAGMENT_FOG).

Subject: [PATCH 085/166] i965: fix broken glBitmap + depth test

When we use the do_blit_bitmap() function, it seems the fragment Z is always
1.0.  If depth testing is on, that means that bitmap fragments are often
occluded by other rendering.  So, the bitmap doesn't appear even if
rasterpos.Z==0.
The fix is to use the intel_texture_bitmap() path when depth testing is on.
Also, fix the incorrect Z coordinate.  It needs to be an NDC value in [-1,1].

 intel_texture_drawpixels().

As for glBitmap, it needs to be an NDC coord in [-1,1].

Subject: [PATCH 087/166] cell: allocate batch buffers w/ 16-byte alignment

Replace cell_batch{align,alloc)*() with cell_batch_alloc16(), allocating
multiples of 16 bytes that are 16 byte aligned.

Opcodes are stored in preferred slot of SPU machine word.

Various structures are explicitly padded to 16 byte multiples.

Added STATIC_ASSERT().

No real idea what this does.. but a lot of things that misrendered and
made the GPU throw a DATA_ERROR now work..  I'm wondering what side-effects
we'll see from this :)

Copied language from the glXSwapBuffers manual page about the implicit

Subject: [PATCH 111/166] gallium: Disable memory debugging for Windows OGL.

Unfortunately both Mesa and Gallium use the same defines for memory
allocation (MALLOC, FREE, etc), and worse, some times memory is allocated
with one set and freed with the other set, causing the homegrown memory
debugger to trip on itself.

In the future mesa and gallium should use different names, but for now,
memory debugging on Windows will have to be carried with different tools..

Subject: [PATCH 123/166] Treat image units and coordinate units differently.

Previously MaxTextureUnits was used to validate both texture image
units and texture coordinate units in fragment programs.  Instead, use
MaxTextureCoordUnits for texture coordinate units and
MaxTextureImageUnits for texture image units.

Fixes bugzilla #19468.

Subject: [PATCH 131/166] i965: asst. fixes, work-arounds for FBOs and render
 to texture

OpenGL allows mixing and matching depth and stencil renderbuffers in
framebuffer objects while the hardware really only supports interleaved
depth/stencil buffers.  This makes for some tricky buffer management.

An extra wrinkle is the situation where the user allocates a 16bpp depth
texture or renderbuffer then tries to render to it along with a stencil
buffer.  We'd have to promote the 16bpp Z values to 24-bit Z values and
mix in the stencil values to setup the depth/stencil renderbuffer.

There's no support for that now, so always allocate 32bpp depth textures/
renderbuffers for now.

Subject: [PATCH 154/166] egl: Add a egl state_tracker that use Gallium

	This works on top Gallium and KMS. The only thing that
	does not work currently is swap buffers for shown mesa
	screens. So the only fun thing this will produce is a
	white screen.

	The driver wishing to us the state_tracker needs to
	implement the intrace as define in drm_api.h located
	in gallium/include/state_tracker. And also have a
	working KMS implementation.
