intel: Replace intel_renderbuffer::region with a miptree [v3]

Essentially, this patch just globally substitutes `irb->region` with
`irb->mt->region` and then does some minor cleanups to avoid segfaults
and other problems.

This is in preparation for
  1. Fixing scatter/gather for mipmapped separate stencil textures.
  2. Supporting HiZ for mipmapped depth textures.

As a nice benefit, this lays down some preliminary groundwork for easily
texturing from any renderbuffer, even those of the window system.

A future commit will replace intel_mipmap_tree::hiz_region with a miptree.

v2:
   - Return early in intel_process_dri2_buffer_*() if region allocation
     fails.
   - Fix double semicolon.
   - Fix miptree reference leaks in the following functions:
       intel_process_dri2_buffer_with_separate_stencil()
       intel_image_target_renderbuffer_storage()

v3:
   - [anholt] Fix check for hiz allocation failure. Replace
     ``if (!irb->mt)` with ``if(!irb->mt->hiz_region)``.

12 years agointel: Fix swrast_render_start() for depthstencil buffers with separate stencil

intel: Fix swrast_render_start() for depthstencil buffers with separate stencil

1. Don't map the depthstencil buffer twice

   Place a guard in intel_renderbuffer_map() to prevent a renderbuffer
   from being mapped twice. This happened if a single buffer was attached to
   the framebuffer's depth and stencil attachment points.  (Interestingly,
   because intel_map_renderbuffer_gtt() is idempotent, the double mapping did
   not cause bugs for depthstencil buffers *without* separate stencil).

2. Stop overriding gl_framebuffer::_DepthBuffer,_StencilBuffer

   Normally, if a depthstencil buffer is attached to the framebuffer's
   depth attachment point, then _mesa_update_framebuffer() installs
   a wrapper depth renderbuffer at gl_framebuffer::_DepthBuffer. Ditto for
   the stencil attachment point and gl_framebuffer::_StencilBuffer

   A depthstencil intel_renderbuffer with separate stencil contains hidden
   depth and stencil renderbuffers, which are the *real* renderbuffers. In
   order to force swrast to work, we were installing, in
   brw_update_draw_buffer(), the hidden renderbuffers at
   gl_framebuffer::_DepthBuffer and _StencilBuffer, thus overriding the
   behavior of _mesa_update_framebuffer().  However, now that
   intel_renderbuffer_map() is implemented with MapRenderbuffer(),
   overriding _mesa_update_framebuffer's introduces bugs.  This patch
   removes the override code.

Fixes several Piglit tests on gen7.

fragment shader was updated.  This was discovered while investigating
some spurious code generation for shaders in Cogs.  The behavior in
Cogs is especially pessimal because it ping-pongs sampler uniform

Cogs will still defeat the shader cache.  A lighter-weight mechanism
that can work with the shader cache is needed.  However, this patch at

intel: Fix intel_map_renderbuffer() for depthstencil buffers with separate stencil

For a depthstencil buffer with separate stencil,
intel_renderbuffer::region is null. (The regions are kept in hidden depth
and stencil buffers). Since the region is null, intel_map_renderbuffer()
assumed there was no data and returned a null map pointer, which in turn
was dereferenced (!) by MapRenderbuffer's caller.

This patch fixes intel_map_renderbuffer() to map the hidden depth buffer
through the GTT and return that as the mapped pointer. Also, the stencil
bits are scattered and gathered when needed.

2. Generate the actual ir_call (assuming we found the callee).

Both of these are complicated.  The first has to handle exact/inexact

The second has to deal with void/non-void functions, pre-call implicit

Trying to do both in one function is just too unwieldy.  Time to split.

whether or not it was exact.  (If not, we may want to keep looking.)

This could be done via the existing mechanisms:

However, this requires walking the list of function signatures twice,
which also means walking each signature's formal parameter lists twice.
This could be rather expensive.

This is a band-aid for these two problems:
- The R600 and EG control-flow instructions appear in switch statements
  next to each other, causing conflicts when adding new instructions.
- The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29
  to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST
  is 22:29.

To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23,
or 26 (directly in the definitions), such that it can be just or'd when making
bytecode without any shifting. All switch statements have been divided into
two, one for R600 and the other for EG.

Of course, there is a better way to do this, but that is left for future
work.

mesa: Fix glFramebufferTexture*() for depth and stencil attachments

This patch solves three bugs.

1. When a texture was attached to the GL_DEPTH_STENCIL_ATTACHMENT point,
Mesa attached the texture only to the depth attachment point
    gl_framebuffer::Attachment[BUFFER_DEPTH]
and failed to attach it to the stencil attachment point
    gl_framebuffer::Attachment[BUFFER_STENCIL]

2. When a texture was attached to the GL_DEPTH_ATTACHMENT point and then
later attached to the GL_STENCIL_ATTACHMENT point, Mesa created two
separate renderbuffer wrappers. This caused a GL error in
glGetFramebufferAttachmentParameteriv().

3. Same as 2, but with depth and stencil juxtaposed.

Fixes Piglit test ARB_framebuffer_object/same-attachment-glFramebufferTexture2D-GL_DEPTH_STENCIL

Note: This is a candidate for the stable branches.

i965: Add support for gl_VertexID and gl_InstanceID.

The compiler setup for these VF-uploaded attributes looks a little
cheesy with mixing system values and real VBO-sourced attributes.  It
would be nice if we could just compute the ATTR[] map to GRF index up
front and use it at visit time instead of using ir->location in the
ATTR file.  However, we don't know the reg_offset at
visit(ir_variable *) time, so we can't do the mapping that early.

Fixes piglit vertexid test.

We only allow 16 vec4s of attributes in our GLSL/ARB_vp programs, and
1 more element will get used for gl_VertexID/gl_InstanceID.  So it
should never have been possible to hit this fallback, unless there was
another bug.  If you do hit this, you're probably using gl_VertexID
and falling back to swrast won't work for you anyway.

This also updates the limits for gen6+.
